【 Weak current College 】 how to strengthen urban community fire safety-Power By 【 China power house network 】
In recent years, China's urban community development faster, initially set up a system of community service. At the same time, some from the Government and enterprises, the social function of separating out, by relying on the urban community, but Community fire protection infrastructure and the level of fire management have not been self in a timely manner. To this end, to reinforce Community fire organizations, fire equipment, fire protection, education, fire management, establishing a new Community fire network management, fire protection and service system, becomes a requirement.
The so-called community, that is, in the last century 90 's, the general statutory of grass-roots communities, i.e. Rural Township and village committees, city of neighborhood offices and residents Committee, that is, urban and rural grassroots and grassroots people autonomous organization hierarchy. Community building refers to the leadership of the party and Government, rely on the community, the use of community resources, strengthening community functions, solve community problems, and promote community economic, political, cultural, and environmental coordination and health development, and constantly improve community members of living and quality of life.
In rural areas, to actively develop the strength of local, private fire, encourage and promote the establishment of a mass and part-time coexist obligation and voluntary fire brigades, broad promote socialization of fire system. So, our active-duty fire brigade is dominant and multiple forms of fire brigades of complementary fire system will further toward improving and perfecting the tentacles of the fire safety will also be extended to China's urban and rural areas of the overwhelming majority of the region.
The community is to households as the main body, life, production and management as well as small community area, and the organs, organizations, enterprises and institutions are markedly different. According to preliminary statistics, the total Community fire fires occurred in about 40%. Although the loss or injury is not big, but its great harm, to a certain extent affect the social stability of the current Community fire management status, issues mainly has following several points:
1. how old slum Jane housing, wood frame housing, a serious fire hazard, oversight is difficult.
2. some enterprises and "four small units", fire management was not implemented.
3. Audit without fire and put into use without authorization of acceptance, buried under threat.
4. illegal storage and sale of dangerous articles highlighted the phenomenon.
5, some small workshop "three in one" universal phenomenon.
6, small public entertainment, markets without pre-opening examination qualified unauthorized opening.
Community fire status determines the rate of Community fire, fire, community fire is mainly concentrated in households and some "four small units", fire causes mainly concentrated in the electrical, careless with fire and chemical dangerous goods mismanagement. The fire loss and although it is not possible with other enterprises and institutions in the same breath, but have a direct impact on the family members or owners of work, learning and living, and the community in a dying fire ravaged, often triggered widespread civil disputes, brings a series of social problems, which affect the stability of society. In addition, community members all over the community, extends to all corners of society, so doing community fire work to improve community fire safety and the environment, not only can guarantee the community prevention capabilities, but also to establish a community fire safety prevention system, has an irreplaceable role.
A clear, sound network of the respective responsibilities
Community fire work in community building as well as urban construction, has a decisive role. Fire and community police station proactive and coordinated for home and other relevant departments, according to the "Government unified leadership, fire departments, community management, fire safety and autonomy" of ideas, based on a high starting point, high standard, high quality and good community fire building. First, it is necessary to improve organization. Establishment of appropriate Community fire (fire prevention) fire safety Committee or the establishment of joint meetings, community fire safety meetings. City Neighborhood, neighborhood to clear a leader who is Deputy Director, police station, and communal authorities responsible member. Second, it is necessary to further clarify responsibilities. Street office building community fire into Community law and the main content, develop community fire work plan regular community fire work Conference, guiding neighborhood community fire management, and in the area of the unit certified fire safety responsibilities like, etc. The Commission shall establish the community residents fire security patrol, relying on the Convention to set up Community fire inspection team, within the community on a regular basis, and residential units, and fire exits, fire protection checks carried out on the area of old, weak, invalidity and thought of providing fire safety services, etc. Home, urban construction, culture, education, and public health departments, community fire building content and requirements, to have the construction, guidance, coordination and service responsibilities. Police station to implement community police Pack tablets responsibility, to supervise the area unit, property management, residents Committee to fulfil its responsibilities, fire fighting, fire and police stations to play a supervisory role. Public security agencies should strengthen community fire business guidance, ideas, and to supervise and inspect the community public fire facilities, within the community checks imposed flats, eliminate fire hazards, the resident fire squadron on the area of the flats, residential clearing should endeavor, situation, development of appropriate fire evacuation plans.
Second, to carry out fire safety awareness campaigns enhanced
Fire service is the common responsibility of society as a whole, should strengthen the advocacy work, let the fire department fire safety knowledge into the community so that community residents to acquire basic knowledge about fire prevention, fire fighting skills and basic methods of escaping. Fire in the form of propaganda cannot rely solely on past hanging up posters, banners, etc., should keep abreast of the times, take people receptive manner widely disseminated. One is the right place in the community, such as the Community body-field, farms, community doormen Department set a fixed colorful fire Billboard, image vivid pictures, fire case, humorous stories, such as forms for centralized publicity to remind residents ' daily life in fire-extinguishing, transfer and evacuation ofA variety of skills, enhancing fire safety awareness. Second, the combination of fresh selection of civilization, civilized unit, posting fire safety tips card, on the units within the community and disseminate knowledge, to launch find fire and eliminate risk. The third is the use of the community's existing electronic advertising screen spots fire publicity warning to alert the public about fire. Fourth, you can post fire awareness public service advertising signage. The fifth is for different seasons, the characteristics of the different groups in various forms of promotion and education activities, particularly for children, sick people to increase fire safety knowledge of propaganda, relying on the masses to self-promotion, self powered, enhancing fire safety awareness residents. VI is to strengthen the efforts of the open-fire station, often organized students and community workers to the fire station visit. To actively create the "no-fire community activities", in a timely manner to promote community fire work of new things, new experiences, so that the whole community formed a good fire safety atmosphere, so that the masses of self awareness and social monitoring capacity.
III. reinforce Community fire facilities improve community fire environment
Public fire protection infrastructure is an important community fire protection material base. New community or transformation of the old city, in accordance with the national fire technical specifications require planning and construction, fire station, fire exits, fire-fighting water supply, fire communications public fire facilities must be synchronized with the community design, the construction of the synchronization. Conditional community, the establishment of TV monitoring and alarm system, surveillance Center Watch full screen TV surveillance within the community the appearance of the streets and buildings.
To rely on community police station installed alarm calls, configure fire equipment tank with small trolleys of firefighting and rescue equipment, placing hose cart, water gun, fire extinguishers, combat clothing, etc., in the residential building configuration of fire extinguishers, at any time accept residents ' for help.
IV. sharing human resources building mass prevention treatment management network
Community fire work is community-building an important aspect of the work, must be under the leadership of the local government, rely on the community's overall strength, humanist, doing community fire building. First, we must firmly grasp with quick-fire of ideas. Community's agencies, organizations, enterprises and institutions, and residential property management unit into mass prevention system overall consideration, establish a standard of reasonable community fire works. Second, it is necessary to strengthen the human with the community, the obligation of the construction. Strengthening institutions, enterprises, institutions, fire defense forces and establishing the obligation of professional or fire brigades, fire prevention, fire fighting and early defense. Third, it is necessary to create a "safe and civilized communities". Safe and civilized community is in the new work situations, fire safety, an effective carrier is the symptoms, lies at the root of proven important measures, should become Community fire plays for construction. Party committees under the leadership of the Government, carry out safe and civilized community activities, and to create activities to suburban and rural residents in the community. The fire into the "Star" civilized family and civilized unit selection. Fourth, we need to implement dynamic fire management, self-inspection, inspection, and eliminate fire hazards. Residential property management unit to conduct regular fire safety inspections, fire protection within the community, the protection of the community channel flow inside of a public fire facilities, equipment, and fire safety signs are good. Neighborhood to establish fire safety inspections group, regularly on community building facilities and fire protection of public fire protection facilities inspection and maintenance, went from door to door on residents of the household appliances, the use of fire gas equipment for fire protection, fire suppression vehicle occupied and damaged fire channel, community police must supervise the responsibility area units, tenants, property management unit or fire duties, organize regular fire safety inspections and timely eliminate fire hazards. Fifth, to ensure communities have a certain fire funding, the Government has made community construction into the budget, the Fire Department to communicate actively with the relevant departments, community fire requirements into the Community budget, taking into account the Community fire work has a certain amount of money and material basis.
Economic development, social progress, the quality of life and improve the living environment of increasing demand. Fire safety and masses of production and life are closely related, extensive evidence to create a good fire safety environment is a work based on the basic guarantees of social stability. Through the construction of urban community fire, both settled because of the Fire Department, police, and would like to grab a task without energy dilemma of catching and let the community staff actively participate in the work to the fire, not only ensuring communities have a good fire safety, environment, and improves national fire safety awareness. Truly everyone involved in the fire safety, prevention and mass treatment, that Community fire safety in the maintenance of city plays the role of the first line of Defense.
【 Weak current College 】 Beijing Subway fire rescue system status---Power By 【 China power house network 】
MTR is an important part of the urban traffic because of its high speed fast becoming an important means of transportation in Beijing. Beijing Subway transport, personnel density, in the event of fire, it is easy to result group dead injury hazards, the consequences would be unthinkable.
1 Beijing Subway status
Beijing Subway project was opened in 1969, an existing line, link two operational lines, full-length 54km, including 39 operating station, original design, passenger volume 30 million now, maximum passenger capacity has reached more than 200 million peak hourly maximum cross section 2.4 million passengers transported persons 15.45 million people/hour, subway electric buses each car as much as people are often 245 where 300 people, bus transport and facilities design exceeded the carrying capacity of serious.
The main characteristics of the subway fire 2
2.1 smoke and high temperature of the disastrous great
Metro fire, cable, decoration materials, combustion will produce a lot of smoke and heat, due to the relatively closed, toxic smoke will soon filled with tunnels and buildings. Based in Metro platform level simulation result of fire, 2.8MW ignition after platform layer 6min filled smoke, visibility was almost nil, smoke diffusion speed is average 1m/s. In this condition, the staff level, the average walking speed 0.33m/s, stair-walking speed average 0.29m/s. Personnel from the underground station to the ground evacuation, hot smoke rising from the ground up, and the evacuation of passengers in the same direction, but also increased the smog's influence on evacuation personnel. High temperature smoke also on human physiological and psychological cause strong stimulation, people tend to lose your rush to escape, confusion and congestion. Smoke also causes people of asphyxia, as smoke reach people in the head, the carbon monoxide content of 0.5% smoke hot temperatures exceed 43.3 ° c, air oxygen content of less than 14%-18%, it will make people's life in danger.
2.2 evacuation difficult
Beijing Subway within very narrow self-sealing, each tunnel width, except for passenger cars accounted for 4m to 2.56m, there is only a side 67.5cm. If a passenger train accident stopped at two points in the interval of the tunnel, passengers even if they can beat the car door and window jump, because people more crowded, almost no station feet. In particular, on the left side of the road direction, there is a live three-rail, if not cut off the power, jump back also occur a shock hazard. Where pyrotechnics, the platform column, ticket, step, and so have become the obstacle of evacuation.
2.3 fire suppression difficult
Metro fire, smoke, not long accumulation of poor visibility, it can cause difficulties for firefighters reconnaissance, unable to quickly find trapped passengers, locate fire points, it is difficult to quickly organize effective fire fighting. Metro fire, accident area must wear oxygen cut off-gas and air (oxygen) to put the fire breathing apparatus, protective equipment affect the fire fighters of liaison and tactical action and increase the strength of consumption, to the great fire-fighting operations. Subway all kinds of wireless communications equipment power of decay and even fire command cannot be used to contact difficulties. These are increased Metro fire extinguishing and rescue work.
3 Beijing Subway fire rescue work problems
In response to Beijing Metro possible incidents, in recent years, Beijing fire station did a lot of preparatory work, the purchase of a large number of fire fighting, rescue and protective equipment issued units, increased Metro fire-fighting and rescue capacity, but there are some problems.
3.1 for fire-fighting for help Metro Police shortage
To Beijing Metro current traffic, during peak times, stations passengers can even reach thousands of people. Beijing Xidan station on the subway fire drills found that two firemen wearing breathing apparatus in a small amount of air in the smoke conditions stretcher to the platform in a "injured" to the ground, to time consuming about 15min, reach the ground after the firemen had lost because of fatigue. When you need a large number of subway fire firefighter arduous search and rescue, fire fighting, visible police presence is enough to become a fire-fighting and rescue the success of a critical factor. To successfully complete the firefighting and rescue tasks, you will need in the early stage of fire dispatch enough rescue personnel and equipment to the site.
Beijing fire brigade existing 57 fire Squadron, 2800 employees participate in fire-fighting and rescue officers and men of the first line of fire, of which 13 Squadron is located along the subway. From team building and team station stations distributed, Beijing fire still far meet national standards on team building, if the relevant requirements of the urban areas a subway station fire accidents for rapid mobilization of fire officers and only 300 ~ 500, you can dispose of smaller-scale disasters, if you have hundreds or even thousands of people trapped in the mega-disasters, will not be able to meet the firefighting and rescue needs.
3.2 response training, subway fire drill is insufficient
Increase of fire-fighting and rescue from training and drills from time to time. Beijing fire station you can take the underground fire hot training venues and only one, small, simple design to meet the city's fire officers and training needs. Because Metro long, every day in the subway uninterruptible, internal organizations combat exercises very difficult operation time walkthrough may boot up mass panic, adverse effects, so the initial walkthrough must later in the night outage. And exercise if you use large tunnel fire extinguishing equipment (such as Land Rover 60 snow vehicles) into MTR internal site walkthrough, it is easy to result stage, platform, and other facilities damaged, Walkthrough or ground water or manufacturing large amounts of smoke and fire points, for fear of impact on the second day of operation, the practical effect cannot impersonate, resulting in a considerable number of officers and men did not dispose of subway fire experience, objective difficulty caused fighting。
Considerations 4
Metro is the relationship between people living in major public facilities, is the focus of fire protection, if you want to do a subway fire protection work requires multiple parties with various departments. Beijing has developed a subway fire rescue plans issued by departments, as well as the Fire Department to configure, update, a lot of new equipment and special equipment, subway fire enhances Beijing Shi Metro fire. To put fewer cases further mitigate these problems, have a few ideas.
(1) on the stations staff professional fire-fighting and rescue training for its equipped with high performance fire-fighting and rescue equipment and protective equipment. Because the fire had spread, early, heady, off, several stages, in the initial stages of the fire, fire control and easier to reach the fire spread and violent phase of the fight can be difficult. Subway station workers found fire early, when the fire in the beginning stages of General, professional fire brigade could not get at this time, if the organization staff alerts while leveraging efficient extinguishing equipment for the initial fighting, it is easy to put the fire under control, significantly reducing development as the probability of a major fire, then to the professional firefighters reduce great pressure, indirectly made up for the lack of fire-fighting forces.
(2) asked by the relevant departments will organize practical exercises in Metro simulation as a system, such as the provisions of the Beijing subway system and the Fire Department must organize a joint fire rescue exercises, strengthening the Fire Department and the staff of subway fire rescue disposition.
(3) relevant sector investment construction facilities of fire simulation exercise Center, one can fire personnel system of training, the second is to fire hall open to the public in the form of public inspection fire feelings, learning to fire escape knowledge, enhance awareness of fire prevention.

【 Weak current College 】 civil buildings fire analysis and intelligent leakage application of fire-alarm system
Civil building contains two most, public gathering areas and housing. Public gathering area means shopping malls, markets, hotels, theaters, stadiums, dance halls and other places, to provide a comfortable shopping, accommodation, entertainment environment also because you want to use a large number of electrical equipment, facilities, increasing the risk of electrical fires; and people's standard of living is increasing rapidly, will also use more updates of electrical home appliances, and these appliances direct contact of the vast majority are the only use common sense and do not have electrical expertise of ordinary people, not regulated power customary and mobile extension socket abuse also enable domestic electrical fire incidence has been increasing.
First, there is a fire of some statistics
Based on reliable data and statistics, only the first half of 2007 the total national town, death fire 95336, injured 488 898, direct property losses of nearly $ 5 b, visible fire resulting in bodily injuries and economic loss is very high. The State Department has developed the production safety accident reports and studies dealing with regulations, such as a series of prevention and assistance measures, the competent authorities of all levels on fire prevention has also been given great importance given by the national fire trend steadily down. However noteworthy that, due to electrical failure was caused by the fire on a yearly basis, according to preliminary statistics, about 10 years ago by 4-5 times the number of fires which occurred more than a quarter. In electrical accidents in the fire, the electrical equipment accounted for 10 per cent, line 52.0 percent, electrical equipment and apparatus 36.4 percent (including lighting apparatus 10.6%), other 1.6 per cent; heavy, oversized electrical fires, their causes short-circuits accounted for 52%, overload or 4.6 percent, bad 12.6 percent, overheating 18.5 percent, leakage 1.8 percent, 0.5 percent, lightning strike, electrical fault accounted for 10 per cent.
Second, the results from the fire statistics to see China's electrical safety standards
From electrical accidents and fires caused by the statistics known. China's electrical safety system has not been thoroughly penetrated into the base, some on electrical safety, work in dereliction of duty, and does not strictly follow the rules for using electricity for the operation of phenomena also occur from time to time, these are causing the root cause of electrical fires. As China's economy continues to grow, electricity consumption is also growing rapidly, therefore by electrical accidents caused by the fire, there is also a rising trend.
Most of the electric fire accidents are due to electrical equipment running artificially raised in violation of the rules of operation, for example forgot to disconnect the electrical power supply, the electric heaters on drying clothes, etc., these are not normative power lead to the typical cases of fire; the use of, the provisions do not conform to the manufacturing of electrical equipment and installations is another electric fire dangers, for example, incandescent (or other heat large light source) and electric heaters, etc. due to overheat and ignite combustibles; there are around a large part of the reason is because the wire overload, over current protection device characteristics of poor or shorted wire protection switch, fuse, caused a power circuit and grounding, are supposed to pay attention to the electric fire hazard.
In sum, the electric fire causes and prevention has several noteworthy:
1. a public gathering areas most serious electrical fire hazards are electrical devices, circuit temperature is too high, on the one hand, in engineering design because there is no good off the wire selected is too small or too low temperatures cause lines, electrical lines of deficiency, spark or transformer grounding wire? contacts, power distribution, bus and cable tray, fuses, etc. are present because of poor people as the construction of the local temperature increases are fire hazards, the supervision and inspection in fire or electrical device detection process can be used by help of thermal infrared imager and other testing equipment for thermal and heat, you can use ultrasonic detector to find electrical wiring, equipment received and brand impact of virtual phenomenon, and so on, you can use infrared devices such as a nod to measure specific parts of the body temperature.
2. Construction and installation are not standardized, cause electrical equipment failure. The exposed wires, cables, connectors, the phenomenon is most common with lights, common mobile socket, power distribution unit Cabinet air conditioner, advertising lights, power cable connector exposed. Suspended ceiling, decorative wall cable shaft, counters, cabinets, concealed inside the outlet the power supply cable connector exposed also prevalent;
3. Electrical equipment and fuel companies did not take effective measures, increased risk of electrical fires, for example, some electrical device installed directly on the combustible components, or electrical equipment using flammable objects such as boxes, in everyday life, the most common is the air switch, leakage breaker, ballasts, lighting control switch, outlet directly installed on wooden boards, etc.;
4, electric line laying protective measures are not in place:
(1) ceiling-mounted parts electrical lines laid in the most serious problems. For example, a wooden ceiling luminaire wiring not wearing protective tube; downlead suspended ceiling or in the cable harness into ceiling-mounted luminaire does not take protective measures; ceiling luminaire wiring through pipe protection are not in place of phenomena occurred from time to time, and some have even wear hose wire but still have the exposed part or distribution extension protection tube are not introducing a junction box or apparatus;
(2) wire, cable in the wall, metal components, combustible components do not take protection measures, and some wires, cables, do not wear metal protection pipe laying in flammable decoration dissection or wear within. wooden curtain walls, stairs, walls between the cable access distribution box wear steel pipe mouth did not do proper protection measures:
(3) indoor electrical line laying position. Electrical line laying position and heat source too close distance, such as: a flashlight (especially heat high lights) power cable attached to the heating pipe laying. or power covered wire near the radiator, metal pipe laying, winding in metal tubes, etc.;
5, the mobile extension socket problems, especially, whether it is a public place or a family, mobile extension socket problems are more and more, many bad socket does not use qualified insulated and sheathed, mobile extension socket threaded wire using, electricity, water-proof measures need to be takenPlaces (such as restaurants, shops selling flower beds, washing machine, fish tanks, etc.) do not use waterproof mobile extension socket, etc.;
6, Terminal wire crimp is not normative. Air switches and breakers of terminals and neutral line bus terminals, the Terminal crimping multiple wire or stranded conductors without Terminal crimping, crimp terminals crimping weakly happens from time to time;
7, management measures are not in place. Warehouse stacked vertically below the luminaire combustibles; generator and fire boilers and other combustibles in a room with reset; distribution Cabinet stacked debris around; lighting and too close to combustibles distance around; cable ditch legacy are combustible debris, etc.;
8, a lot of fire power equipment, facilities and other reasons due to the construction itself exists to varying degrees of fire hazards. Design and calculation errors in the selection of fire power equipment or wires overheating or fire sporadically in fire inspection also often find fire distribution box Terminal temperature thermal or electrical equipment have been destroyed to no effect, as well as air switch shell burnt, wire connector outside insulation ageing, breaker crimp is corrosion causing bad, etc., such fire-fighting, fire protection circuit, not only in fire, does not have the effect, become the cause of the fire should be attention to;
9, shaft, 7 ㈠ with not take fire blocking measures, tall buildings cable well in each floor office fire sealing has been made, the transformer naked bus and other electrical equipment through the fire wall cavity is not implemented, such as fire sealing makes the flame through shafts or other pathway yanran, resulting in greater loss.
You can say, our country's security of electricity will also need to do a lot of work. According to the fire department fire statistics, it is not difficult to see from electrical faults caused by the fire is on the rise: this required in the manufacture of electrical equipment, appliance or electrical installation, maintenance, you should strictly follow the rules for the construction operation, doing every procedure, every detail perfect. Fire hazard mostly because of violation of fire regulations and fire protection technology standards, and therefore to determine whether a safety factor not only pose a fire hazard in the fire chief on the laws and regulations, but also in fire protection technology standards have also been based on.
In everyday life, and high-pressure distribution transformer system contacts are professionally trained and experienced professionals, due to the high-voltage thrown in, electrical accident frequency much lower than with the general population exposure to a wide range of low-voltage systems (AC220/380V). Therefore, low-voltage electrical installations for fire prevention measures in the electrical engineering design, construction and daily use and maintenance has become particularly important. People in a century of electricity, and gradually perfected on different voltage level of protection for low-voltage equipment of protected content are over current protection, ground fault protection, overvoltage and less voltage protection, earthing and equipotential bonding, insulated or quarantine measures and special places and special equipment for protection. These measures not only effectively protect the personal safety can also fire prevention electrical failure.
3. used for fire prevention measures leakage protection
Residual current protection related knowledge: in the low-voltage distribution system, any of the electrical equipment is a node, the device current is a vector, at any time into the outflow of vector and should be zero, that's familiar to Kiel-g's first law, as long as the device's current does not "leak", then the device insulation is reliable. If the device or the power supply line insulation fault occurs. then current will return to the Earth, the current transformer is an exciting role, the current mutual inductance coil and switch tripping mechanism connections. the transformer excitation of the differential current exceeds a limit, switch will action, as protection switch trip depends on fault current has nothing to do with the voltage.. This switch is called a residual current protection switch. Thus the residual current protection and earthing protection. in order to make the current in the insulation failure to complete the circuit, requires protection of electrical equipment must be grounded,
For normal work of used appliances and the laying of lines, residual current protection switch should not, if there are residual current circuit, regardless of the existence of this current is flowing through protection line (PL) of the PCT or protection switch and no electrical devices but there fault current line (e.g. for wires insulation damage through the metal protection pipe flow to the Earth's residual current), residual current protection switch should be timely action, cut off the circuit. Therefore, the fault-current protection switch to prevent grounding current fire of electrical installation system can also play a large role.
Residual current under what conditions can cause a fire? in General, when the fault free release of energy to be ignited flammable objects when the open flame and thereby cause a fire. The majority of electrical fires are caused by ARC, after extensive tests and practical experience shows that several hundred Ma small current can create arc, applied residual current protection switch for fault current protection can effectively prevent electrical line of fire.
4 short circuit arc of fire prevention
Short circuit arc of fire in the majority of the grounding caused, AC220V, 300-500mA of current is enough to produce the arc, residual current protection switch (RCD) timely and effectively cut off the power switch, or you can send a signal. as soon as possible in identifying, avoiding the occurrence of fire. At the same time, using the residual current protection switch can also be hidden on ground fault played a preventive role, for example due to improper construction results in neutral and Earth wire received wrong, or the construction of the cable insulation damage inadvertently make RCD alert or action, this is because the leak current line by PE by Earth return to power, the total incoming Department current vector and is not zero, the RCD action occurs or signals, only exclude ground fault, eliminating the risks, protect switch to reset.
In order to effectively avoid personal electric shock accident and ground fault arc fire, in accordance with the standards, IEG in building sets two-or three-level RCD.
(1) configuration levels of the programme: RCD at the end of the loop on setting 30mA or 10Instantaneous RCD 0mA, and set when the rated current for 5 times the maximum operation time for the front end to power 0.04s; gas line Office, should be set to delay action 300 ~ 500mA smart choice-RCD, its action is not the smallest 0.15s action time as 0.05s.
(2) configure the third-level programmes: RCD and configuration levels comparison of RCD, its extra III RCD General fixed delay type (such as in 1s delay, 1 △ n take 1A), the level of the RCD is scoped to the zero sequence transformers, generally used for fire signal system, the only alarm not actions (such as needs can also be scoped to the breakers actions), to large buildings often require the installation of three-level RCD.
5. set the leakage of the causes of fire alarm system
Building power Office installation with residual leakage protection function of the circuit breaker or into line circuit breaker and residual current protection independent of the remaining switches use is effective in preventing electrical short fire. In the sustainable development of China's economy today, because people on safety specifications in-depth knowledge of electricity, making the electrical failure caused personal injury accident gradually, but each year by the electrical accidents caused by the increase in the number of fire, and fire-on-year decline in the number is in sharp contrast to the trend. In the 1980s, the RCD as preventing electrical fires a measures to promote, my many provinces, including some in developed economies are not enough attention, some construction units and designers even believe that installation is optional or RCD protection is not necessary to use some favour! RCD's designers also due to various reasons only has designed a two-level, allowing the building to memory is not being blank line fire protection district, so there is a certain line of fire danger, and our current promotion "people-oriented" humanity is alien to a harmonious society.
RCD applications standardize in countries in fact, such as the low-voltage distribution design code GB50054-95 no. 4.4.21 bar: "in order to reduce the ground fault caused by electrical fire danger and installation of leakage current protector, the rated current shall not exceed 0.5A"; and if the senior civil building design fire protection standard "GB50045-95 (2005 Edition) new section 9.5.1:" fire hazard in high-rise buildings, personnel are crowded, and other places to set current fire alarm system "; the building design fire protection standard of section 11.2.7 GB50016-2006 provides a desirable set leakage fire alarm system.
It must therefore be fully aware of the power set at RCD protection feature is important for preventing electrical fires, as one of the initiatives for low-voltage electrical equipment unceasing development, residual current protection for some technical problem has been overcome, the leakage current fire alarm system in the civil architecture of lay the Foundation. The doctrine of "complementary" buildings》 intelligent leakage fire alarm system, "a chapter as the new system be replicated on the ground that the system will monitor, analysis, alarm and control integrated and unified management, due to the central computer involvement instantaneous analysis and manipulation of data. The system consists of multiple monitoring subsystem, proprietary software, computer network, the full realization of a teleoperation, telemetry and remote control, to timely implement electrical fault alarm and cut off the power to effectively prevent the occurrence of electric fire, thereby protecting the whole low-voltage electrical system. At present, the "intelligent leakage fire alarm system" as a new advanced protection measures have been Fire Department, construction drawing examination centers and fire engineering workers, as a pre-alarm system, its better than the automatic fire alarm systems and fire protection system that can advance warning and to take emergency measures, to minimize the loss of the user to a minimum, result in engineering design should strictly follow the specifications set "leakage" of fire alarm system.
China electrical fires in all types of fire in a considerable proportion of electrical fires high characteristics, is also a need to formulate an electrical fire in the special laws, at the prevention of the occurrence of electrical fires. United States and Japan and other developed countries have laws and regulations relating to the electrical specialist, such as the United States national electrical safety code (NFPA70), Japan's electric utilities Act, etc.
The advantage of foreign management system in the following areas, for reference: (1) electrical safety regulations drawn up a detailed, comprehensive, easy-to-Manager of operations; (2) the specification of legally binding, in accordance with the law on electrical design, installation sector qualification certification, particularly in the electrical safety of staff and regular examination of qualification license thousands raised the level of the professional skills and competence; (3) the management bodies, regardless of where they are established inspection, electrical installation and construction does not leave gaps; (4) use the units (including industrial building, civil construction and residential) electrical safety awareness and a stronger insurance awareness, promote electrical safety management; (5) the product quality is preventing electrical fires determinants, Japan electrical supplies ban Act implementation and continuous improvement to ensure electrical safety, fire prevention success stories. Therefore, to formulate the relevant national electrical safety standard, and this specification should have a higher legal force, it is mandatory that all industries should accordingly draw up specifications for various types of the child and the rules and regulations, such as electrical wiring, electrical equipment, such as design specifications for fire prevention, fire safety design specifications for electrical equipment, as designers, builders, and audit, inspection and electrical units of power of norms and standards of conduct.
【 Weak current College 】 fire pump main standby switch method comparison
Fire pump main standby switch is to ensure that fire standby pump operation. Its switching method lies in the choice of control signals. This article by two fire pump main standby switch method comparison, analysis, presented in fire water supply system uses a pressure signal control methods better than current signals, and suggested that the fire pump main standby switch uses the pressure signal control method.
Keywords: fire; fire standby pump; switch; compare
Fire is fire water supply system of the heart. In fire water supply system, set fire standby pump can increase overall system security, and help to improve the overall reliability of the fire water system. Based on national standards for the building design fire protection standard (GBJ16-87), in addition to the outdoor fire water consumption not exceeding 25L/s in factories, warehouses, and seven to nine layers of unit residential, fixed fire-fighting pump should be equipped with standby pump, its working capacity should not be less than one main pump. The tall buildings design fire protection standard (GB50045-95) article also stipulates in 7.5.3, fire water system should be set the alternate fire pump. Fire pump main standby switch is fire standby pump into an important means of human work, and also the fire water system reliable and safe operation of important aspects.
1, fire pump main standby switch method
From the fire pump start signal acquisition and control perspective, the design of main standby switch has two methods. The key is to control the signal source selection, it can be divided into current signal control and pressure signal control method. Usually the main fire pump is required press the standby pumps each alternate approach to design.
Current signal control method is now in the fire protection design fire pump main standby switch of commonly used methods. It through the pump motor current signal feedback, to determine whether a fire pump. When the motor circuit (power off), excessive current, the power automatically switches to another pump motors, stopped the first fire pump work, start another pump is working.
Pressure signal control method is in the fire pump water mains pressure gauge with electric node on the set, as in Figure 1, the fire pump main spare switch is determined by the pressure gauge signals to judge. When the fire pump control box received the action directive, immediately start any fire pumps, fire pumps working electrical pressure gauge indicate that the node does not achieve the set pressure value, the control box will automatically switch to another fire pump to start work.
Of course, the electric fire pump control principle that can be optionally specified a fire pump-pump or the alternate pump. Current signal control method in the current domestic uses the earliest, most, while the pressure signal control method in the sprinkler system to start the application, the pressure signal control methods on the fire water system of automatic control provides a reliable way.
2. main standby switch methods
2.1, fire pump failure cause analysis
Fire pump failures the end result is a fire pump can not be normal water. Result in fire pump failure of main reasons can be divided into two categories, one category is motor failure, another kind is the pump failure.
In motor failure, power issues, such as the power supply is not functioning properly due to power failure, the voltage is too high or too low, and so on; the motor itself, such as damage due to the motor to run; motor overload problems, motor-driven pump shaft power is too large or pipe plug, form the current is too large to stop working, and so on.
In pump failure may be due to the water pump bearings, impeller and other issues. According to the experience of engineering practice, motor failure probability to a pump failure probability is high.
2.2, fire pump main standby switch methods of analysis
Using current signal control method, its advantages are promptly reflected motor failure. But motor failure is also the main pump units. But this method does not indicate whether the water pump is real.
Using pressure signal control methods that can truly reflect the actual fire pump work its switching signal credibility is high. Regardless of fault or the fault of pump motor, so long as the fire pump outlet pressure did not reach a certain pressure value, you need timely switch master alternate fire pump. However, the pressure signal control method has its drawbacks. When the fire water system of the actual yield is large, fire pump outlet pressure drop, causing fire pump pressure switch signal malfunction, stop a fire pump switch to another fire started. Water pump in the switch, restart the need for a certain period of time. So, inevitably causing fire water supply interruptions, delays in the fire. In addition, the pressure signal control methods may also be considered in the circuit design of the motor circuit, overload, overvoltage, phase, undervoltage, overtemperature protection function.
From system view, the fire pump and motor pump unit as a whole, judging the final effect of the water supply is whether water pump units, should use pressure signal control of main standby switch method is more reasonable. In the fire water system water exceed the design value, you can control circuit to expand on the fire pump electrical capacity of design, ensure all fire pump power consumption and electricity consumed in the fire control pump of fire during all fire power consumption is only one part of the overall fire power supply system would not result in a greater impact. This outlet pressure decrease, the timely start another fire pumps, regardless of the original fire pumps shut down problems.
From the perspective of reliability, fire pump water supply system of reliability is concerned with the reliability of structure. Setting the main fire pump spare block diagram of reliability can be represented as a series of pump and motor unit and unit, and the relationship between the parallel relationship between the distance 1.
The entire line of reliability can be simply expressed as R. R = 1 a (1 a R1) X (1 a R2) = 1 a (1 a R1aXRlb) X (1 a R2aXR2b). From Figure 2 that can also be directly seen, enhancing the fire pump and motor reliability of equal importance. If only 1 Motors (1B or 2B) to determine a reliable water supply system is not perfect. Using the reliability of the entire system is in the firePump outlet manifold set signal, this is a reliable and meaningful.
Note that in the fire pump outlet pressure value is set, you should consider the early fire extinguishing with high pressure water tank of water. Therefore, for temporary high-voltage indoor fire water supply system, the set pressure value should be greater than the usual network of water pressure. The other main pumps starting fire, the need to set a certain delay before Judge electric pressure values the pressure gauge nodes, determine whether you need to switch to another fire standby pump. And that will power the node set in fire pump pressure outlet valve after (according to the direction of flow) of fire water supply mains, to spray system to set the fire pump outlet check valve and hydraulic alarm valve group so as to ensure reliable pressure signal.
2.3, two control methods
Current signal control and pressure signal control methods are fire pump main standby switch. Fire pump control requirement is consistent with, and two methods for signal acquisition, the ultimate control of the effect is different.
Reasonable choice fire pump main standby switch manner is of great significance. It is the reliability of the fire water system play an important role in the guarantee. Pressure signal control method to BA real control, especially suitable for automatic sprinkler system.
2.4, pressure signal control problems
In pressure signal control method of design, the need to pay attention to the following questions to ensure that the fire pump master alternate switching reliability.
(1) electric node gauges yishe in fire pump water mains, it should not be set before the fire pump valve (according to the direction of flow). Pressure set value should be greater than the fire water tank of water and high pressure value.
This is because the pressure signal location should be capable of faithfully reflect fire pumps and systems of water supply and operating conditions. If the gauge is located in the fire pump outlet valve and valve before, you accidentally close the fire pump while running, you can display the normal water pressure, the water cycle and the system is not working properly. Hence, uses the pressure signal control switch can also be adjusted pipeline fire pump is not working properly in the water cycle, the timely start another pump water supply pipe.
(2) in the signal control judgment of circuit design, the switches need to set a time delay. This is mainly due to the fire pump startup needs a start time and the current elapsed time, time delay judgment needs to be greater than the above two factors, the General can take 1 ~ 2min. In this way, electric pressure signal control node value is true.
(3) pressure signal control method of switching can be optionally specified fire pump or the alternate pump, you can also switch on a regular basis.
(4) fire control in addition to automatic control, you should have in place (manually) control functions. Fire control pump of the signal necessary to fire control centers to monitor, control and building automation.
In fire power of design to consider adequate fire pump power capacity. The fire control pump of the switch, it is recommended that you do not stop the first fire pump power supply, i.e. the most disadvantageous when two sets of fire control pump power supply design, so that the situation is conducive to meet fire protection water supply system in the overload condition of operating conditions, and to reduce fire pump in the interval of time when you switch, as soon as possible, let the fire pump running, improving fire protection water supply.
3. conclusions
(1) fire pump main standby switch is the key to the selection of the control signal. Toggle the main fire pump is an alternate method of the current signal control and pressure signal control.
(2) in fire water supply system, the pump works uses a pressure signal control methods better than current signal control method. Pressure signal control method cannot truly reflect the condition of the fire-fighting water supply, and reliability of the switching signal is higher. Recommendations in the relevant fire normative explicitly fire pump master alternate switching pressure signal control method.
(3) in the pressure signal control methods used, the switch signal electric pressure gauges should be set in the node fire pump outlet manifold valve or the valve after hydraulic alarm. At the same time, the circuit design of the need to set a time delay to determine pressure gauge electro node value.

【 Weak current College 】 old fire hazards exist and countermeasures---Power By 【 China power house network 】
With the continuous development of the urban construction, the city's overall ability to guard against fire is constantly improving, the weak link in the old fire more highlighted. According to incomplete statistics, the probability of fire in the old account for nearly 50% of the total number of fire. Therefore, I think the old fire safety work should not be overlooked. The following author's old town district of fire hazards and control measures on myself.
First, the main current old fire danger
(A) housing structure, fire resistance rating is low. In the old town, in particular, the intersection of suburbs, most of the residents of the House is brick advice pin stone structure, in the case of three-level fire resistance rating, the old houses, small part 47.2% of four-level fire rating, 3.6%. This leads the overall capacity of fire in the old, prone to burning even camp and group dead fire accident injuries.
(Ii) most of the old town of narrow roads, fire engine cannot directly into the community, the impact of fire extinguishing and rescue work. Most of the more developed in the old main road, smooth, but entered the community lanes, alleys of roads due to historical reasons, the Poles, a violation of housing squeeze more fire channel phenomenon, there is no due early complete planning, congenital form fire channel is not wide enough.
(Iii) lack of water, water pressure, away from the Centre districts more remote old fire hydrant layout unreasonable and partially destroyed, was also exposed occupy, a minority.
(Iv) the dwellers fire safety awareness is not high, the lack of knowledge of fire, and some residents don't even understand the use of fire extinguishers and fire escape skills.
(5) units hallway piled in staircases, combustible debris, plug the evacuation channels.
(Vi) the dwellers safety knowledge with fire power is insufficient, in particular wire aging phenomenon, then chaos phenomenon, with copper wire, replace the fuse phenomenon issues outstanding.
(VII) thought no one care, mobility, easily lead to fire, causing loss of life.
(8) community fire organization staff fire professional business knowledge improvement, inspection found the early fire hazards and disposal capacity to be strengthened.
(9) fire prevention funding without protection.
2. control measures and strategies
(A) establish the mass organization, strengthening the obligation fire-brigade training obligations. In urban communities to establish obligations for the fire brigade, community Director, responsible for the organizations responsible for implementing Community fire safety work carried out within the community, improve the fire-publicity residents fire safety awareness; timely detection and fire suppression, escalation; organization of the duty to act in violation of the Fire Department of learning, training. Fire officers and soldiers and police officers on a regular basis on the community's obligation to instruct the fire brigade, and continuously improve its evacuation, escape and rescue the knowledge, the initial fire. Ensure that Community fire work some pipe, the obligation of extinguishing fire.
(Ii) fire awareness into the community. The Fire Department's police station segment on a regular basis and community leaders to concentrate or partitioning for training to improve their ability to work and fire business level, and their communities to establish publicity spots, door-to-door distribution of information, organize fire Billboard, play, broadcast, and other forms of fire-advocacy. Through awareness raising people's awareness of fire safety, so that residents know basic fire prevention, evacuation, knowledge, mastery and early fire fighting to escape the basic essentials.
(3) the establishment of accountability, responsibility and down enquiries. All stations on the community police of signing responsibility respectively, require all sections of the civilian police regularly on residential fire safety inspections, issued a legal instrument, on the violation of the fire Statute, regulations and in accordance with law and prosecution. On community where major and serious fire segment civilian police implement reverse enquiries, investigate responsibility personnel, ensure community fire work there.
(Iv) strengthening community fire safety of vulnerable groups. Vulnerable groups mainly refers to women, children, the elderly. This part of the human gas small children, the elderly and less fire safety knowledge, mobility. In response to these characteristics and status, it is recommended that the public security departments in the school to establish a school police system, regular student counseling, and school children with the knowledge of the fire. Organize the students around the fire station, kids like fire comics brochures. Thought for the elderly in particular, the establishment of the police station, periodic on-site account information do fire publicity, inspection, guidance, to ensure that vulnerable groups of fire safety, reduce fire caused by the loss of life.
(V) strengthen the execution, according to strict monitoring and investigation. Fire brigade and police stations on a regular basis, for people working on Community fire inspections to check the discovery of fire hazards are issued a notice of correction of the ordered, not on the expiration of the units and individuals are given a warning, a fine, cease and forcibly removed according to the law.
(6) increase the threat of fire safety of illegal construction and road management stalls, a large fire hazard market regulation. By Government-led organization District Public Security Bureau, etc functions: one is to plug the fire channel road building for demolition. Second, organizations and commercial sectors together to have hidden a larger market, requires timely rectification, on expiration cannot be rectified and units ordered line or relocation. The third is to focus on three areas of "fixed" (that is, the timing, location, location).
(7) proposals to speed up the transformation of the old city. To completely change the old housing structure, fire resistance rating of low, fire channel narrow fire safety situation, only to be transformed to the old town.
With economic development, inner fire situation still not optimistic, residents of awareness remains to be further enhanced, community fire funding should further increase investment, and to establish appropriate security mechanisms. The old cityDistrict fire hazard cannot be thorough rectification (such as the recent renovation without development, no old fireproofing, fire prevention Division formation), fire remains the old inhabitants of potential perils. Is to create harmonious community coordination of notes, should lead to government departments and the community.

Design with two large-space intellectualized active sprinkler system, describes as follows:
1. big space water gun (ZSS-25) large-space intellectualized active sprinkler system
Working principle:
ZSS-25 water cannon to detector, water gun integration settings. When the water cannon fire detected by issuing instructions linked open the appropriate solenoid valve, a fire started the fire pump, driven site with alarm sound and light alarm. And the fire signals sent to the fire alarm controller. Fight the fire source, device and then issue a directive to turn off solenoid valve, stop the pump. If a new source of fire, then the system back to the above action.
ZSS-25 series large space intelligent fire suppression equipment spraying parameters:
Type arguments VCC (v) the standard working pressure (MPa) standard launched water flow (L/S) protection RADIUS (m) height range (m)-inlet diameter (mm) ZSS-20220V0.2MPa5202-625ZSS-25220 V0.6MPa5206-2550
ZSS-25 water cannon range of advantages: more distances, traffic more (protection RADIUS 20m, the working pressure is 0.6MPa, shot water flow to 5L/S, installation height range 6 ~ 25m). It's these characteristics, suitable for installation in the car park, gym, wharves, airports, theatres etc. larger venues.
2. Configuring the intelligent fire suppression equipment in large space (ZSD detector and ZSD-40A nozzle) large-space intellectualized active sprinkler system
Working principle: ZSD detectors available 24/7 detection protection all fire within. In the event of fire, the detector immediately launch detection of fire, after determining fire detector open solenoid valve and output signal to the Ark, and start the linkage between the pump to the nozzle spray for fire suppression. Fight the fire source, detectors and then to signal to close valve, water spray nozzle stops. If there is a new ignition system repeat these actions.
ZSD series large space intelligent fire suppression equipment spraying parameters:
Model parameter start time (S) operating voltage (v) the standard working pressure (MPa) standard launched water flow (L/S) protection RADIUS (m) height range (m)-inlet diameter (mm) ZSD-40 ≤ 30DC12-240.12546-2040ZSD-40A ≤ 30DC12-240.25566-2540
ZSD series large space intelligent fire suppression equipment, is directed at the Convention Center, Stadium, etc. larger space, the entire device consists of two parts: the controller and the nozzle. The controller completed on the protection of the scene of the fire of monitoring and some communication and coordinated control. Fire open valve, pipe full of water, spray nozzle automatically rotate evenly.
Basis of protection place, controller and nozzle design can be one-to-one, namely a controller with a sprinkler head, in this way, a one-to-one correspondence with the nozzle ZSD controller, the controller found fire open valve, only their corresponding nozzle spray. This method is suitable for the protection of the space required is relatively high, and are divided into different zones, each interval smaller (usually 10 square meters).
You can also design, in the one-to-many way, a ZSD controller with multiple jets match (matching number based on the installation site of the actual circumstances of the decision). When the controller found fire, open the valve, and the controller of all the sprayer will spray water at the same time, the entire protection space following waterfall rain. The effectiveness of the fight fire is very high. The way for walk-in tall space buildings against fire. As various Convention Center, Stadium, waiting room, waiting Hall, a large warehouse, etc.

5. design experience:
1. light Hall fire hydrant system settings
Jiangsu Province science and historical and cultural center of the core architecture is called light Hall of the Central light Pavilion building, symbol of historical and cultural center of Jiangsu Province in the sciences is open to the public at large; this is the ideal space for innovative large transparent light House almost did not provide an installable fire facilities, such as the wall of the carrier, then truthfully how fire hydrant system design? common practice have dropped on installation, and buried installation, etc., but it is not meet for fire protection designMargin requirements to 1.10 m, after careful deliberation chosen in airports and other large space has been widely used in construction of "Island-style device station" to install a fire hydrant, design in the center of steel pillar four symmetrical layout on both sides of the device, by around 2 meters, and its sides arrangement combined fire cabinet (following extinguishers), the middle and the rest of the space for ventilation, this equipment after set decorated with beautiful and practical, become embellished light Hall of important factors.
2. big space programme identifying the fire fighting system
Light Hall total height reached 23 meters, three-layer pass high Church "Melody," theatre and Auditorium reached 10 to 14 meters, known as normal spray system sets the height of not more than 8 meters, and the automatic sprinkler system design specifications "on the large space of the spray system settings do not make clear that the project is experiencing large space, there are several disposal methods:
A £ ® no nozzle, the action is not taken into account only the fire hydrant system, but this increased risk of fire, nor can it prevent fire from spreading and reduce fire losses.
B £ ® adopt the deluge system. The current specification is not to set the deluge system places indoor clearance height limit values and making provision for the protection area. When the clearance height exceeds a certain limit, or protection area is greater than a certain value, the deluge system is valid, is reasonable, whether there are concerns about the economy.
D adopt a "large-space intellectualized active sprinkler system", this system has the test data, a practice that has been built or under construction Convention and Exhibition Center, airports, shopping malls and many other great space design and use of fire has been successful experience in the areas of Guangdong has launched today, and a nationwide promotion, has proven to be great space proven extinguishing facilities.
Therefore this design choice for large-space intellectualized active sprinkler system, greatly improving the fire safety, is a reasonable choice. Jiangsu Province science and historical and cultural center is a province in adopting a large space intelligent active sprinkler system engineering, has a special meaning.
3. a garage fire systems programme
The garage is located on the first floor, two wings of the garage and outdoor empathy, above the normal nozzle even if nozzle plate collector is installed, the system sets the heat effect is very poor, in addition to winter outdoor pipelines also have Frost crack danger, fire safety, garage spray system use preaction sprinkler system.
4. spray pipe and the characteristics of nozzles
Design largely adopted extended type nozzle, where there are installed, a garage, and the width is greater than 3.6 m less than 4.4 m small compartment, which greatly saves cost saving nozzle, and to leave room for late decorative installation, particular attention in the design of the strength check of water spray, water does not meet the design strength, making the appropriate encryption.
5. rainwater cistern as outdoor fire water tank
This architectural design by Australia Office design, Australia on rainwater reuse attention to reflect, in the Centre of the North and South sides of the engineering design, four rainwater cistern, each pool 200 m, the total volume of 800 m3, design the outdoor fire water, storage, and calls for these four pool cannot repair vent, which reduces indoor fire water tank capacity, increased use of area, and cost savings building. This Rainwater cisterns can provide green water, and fire water, increasing attention to water resources, the programme is precious, demonstrate the concept of ecological building, architectural taste.
VI. conclusion:
Jiangsu Province science and historical and cultural center as the top ten public works projects in Jiangsu Province, fire-fighting facilities, basically covers, many fire protection system, where the large space intelligent active sprinkler system in the province earlier adopted, on large-area, big space building design of automatic fire-fighting water supply had useful attempt. Has a special meaning.
