【 Weak current College 】 public fire---electronic computer centres and facilities for fire-Power By 【 China power house network 】

Electronic computer is able to automatically, efficiently and accurately carry out various functions operate modern equipment. With the electronic application of computer technology, the more common set up their own "management information system", an information system is an electronic computer center. Electronic computer centre mainly consists of computer systems, power systems, HVAC systems and equipment room building four parts. Has been widely used in military, industrial, agricultural production, scientific research. Commercial, cultural and artistic. Electronic computer systems is expensive, once the fire, the enormous economic losses, and as a result of information, data, and other damage to the management, monitoring and control system. 1. fire risk 1. indoor decoration to a lot of wood, plywood and plastic plates, combustibles, ventilation ducts using polystyrene foam insulation, such as combustible material may cause fire resistance performance of the building. 2. the engine electrical equipment, electric circuit complexity, if improper selection or does not meet the requirements, the installation may short circuit, overload and cause a fire accident. 3. electronic computer long continuous work, if a failure occurs, causing insulation breakdown, regulated power supply circuit or high impedance component is bad, fever and caught fire. 4. staff wearing polyester, eye LUN, chlorine or PVC clothing, such as William slippers, generate static spark. 5. used combustible items not timely processing or use of combustible detergent machines and floors, yuhuoyuan can fire. 2. fire precautions (1) electronic computer centres should be set away from the dissemination of harmful gases and production, storage, corrosive substances and inflammable, or built in their perennial poop. Also should not be located in the fall of mined areas, mining, and reclamation of miscellaneous soil, mud, sand layer, ground fault, seismic activity and lowlying areas, but also to avoid a strong electromagnetic field and strong vibration source and the source of the noise. At the same time, must ensure that the natural environment clean, convenient transportation, electricity, water. 2. fire-resistance rating of a building should not be lower than level 2, the crucial point of the site should achieve level. Five-layer above room, basement and the upper, lower or nearby are flammable and explosive danger room must not be installed on the computer. Room and other rooms are separated by a firewall, decoration with non-combustible or fire retardant materials. Information storage devices to be installed in a separate room, the data frame and information counters should be non-combustible material. Host room should have two or more security export, door opening to the outside. 3. air conditioning system with alarm control system with dynamic control. Wind pipes and insulation, noise control materials and adhesive noncombustible should adopt or nonflammable materials. Electric heater switch and fan switch to chain control. Duct through room partition wall and floor Office should be located fire dampers, working temperature is not more than 25 degrees. You can take with separate hangers and other methods to prevent wind pipe deformation. 4. cable shaft and shaft in the pipeline through the floor, you must use the fire resistance rating of not less than 1 hour not burning body divisions separately, cable conduit in the wall through the engine room, and also to set the fire resistance is not lower than 0.75 hour not burning body baffle wall cable should be a metal tube, gap plugging and noncombustible materials applied. Trenches to take moisture and prevention measures, and tiered bite laying signal cable, power cable and the ground. Cable and connection to a solid Cabinet. To set up a UPS power supply system, and or close to the engine room emergency power equipment parts. The power cable from the computer system shall not have received on the load change of air conditioning systems, motors, electrical equipment, and do a shielded grounded. Fire electricity equipment distribution line downlead should wear metal pipe, concealed should be laying in the combustible structure. Strong, weak line cable shaft should be set, but also the addition of glass or other combustible material of the protective shield, high-power lamps of the inlet should wear porcelain, glass and other combustible materials asbestos as insulation and protection. Electrical equipment installation and maintenance, rebuilding and temporary cables should be consistent with the requirements of electrical fire. Battery room should be set by external walls. Step up airflow, explosion-proof electrical equipment should be. 5. engine room outside should have good lightning protection installations. Facilities, equipment, grounding resistance shall be in accordance with national provisions of the relevant standards. DC system earthing and lightning distance should be greater than 5 meters, AC and DC circuit shall not close parallel, cross-laying, cannot be shortened or mixed. The engine should use a fireproof performance of antistatic floor. 6. Visual set fire auto-alarm, automatic fire extinguishing system, and to avoid electromagnetic interference may be incurred by the regional or equipment while supporting set fire control rooms. It should also be provided with an uninterruptible power supply of private fire and DC standby power, and should have both automatic and manual trigger. Set the automatic fire-extinguishing facilities area, its wall and fire resistance of the door should not be less than 1 hour fire resistance of the ceiling may not be lower than O.25 hours. 7. computer center should strictly forbid storing corrosive substance and inflammable. When must first turn off the device, and then make the job, and avoid using flammable solvents. Use of various power tools should cut off the power immediately and replace it. All workplaces should be non-smoking and fire at will. Staff should have the necessary knowledge and skills for fire-fighting, the person on duty daily to scheduled to fire safety circuit check. Should be equipped with portable gas fire extinguishers.
