Electrical fire detection conditions, methods and content

First, the basic electrical fire detection conditions
1, should be in the electrical installation and wiring by 1h above-load operation, on entering the heat-stable State for detection and measurement.
2. should the client side for technicians on site support.

Second, the main electrical fire detection tools
The use of modern high-tech equipment, such as infrared thermometer temperature measurement, infrared TV scan, infrared camera shoot hot spectrogram and the use of ultrasound detectors measuring abnormal temperature, spark discharge and other phenomena and use conventional electric instruments, instruments such as voltmeters, ammeters, electroscope, grounding resistance tester, TRMS ampere meter, etc, on the operation of the electrical facilities of various operating parameters for measurement and use of Visual methods, control the relevant technical specifications, to run in high-voltage electrical equipment installation, use, maintenance, and maintenance of electric fire detection.

3. check (logging)
1, the transformer room
① Visual inspection of the set transformer room location, fireproof grade and hole sealing; transformer set, Visual quality, components, integrity and fire prevention measures; high-voltage cable (wire) installation, etc.
② with infrared thermography transformer windings and high-low cable (wire) contact temperature and beat the heat map.
2, high (low) voltage distribution equipment
① Visual inspection, high (low) pressure distribution equipment settings, installation quality, inside wiring, high (low) voltage cable (wire) connector, complete grounding, accessories and fire prevention measures, etc.
② with conventional instruments to measure each phase line voltage (flow) value, N lines of unbalanced current value, PEThere are no abnormal current line and the grounding resistance values, etc.
Û infrared series instruments measuring wire and connection points, switch contact temperature and beat the heat map.
3. low-voltage power distribution box (spare)
① Visual inspection distribution box (spare) settings, material quality, installation quality, inside wiring, wiring terminal connection, Earth and fire prevention measures, etc.
② with conventional instruments measuring load current value, N line current value and there are no exceptional PE line.
Û infrared series instruments measuring box (spare) in the Terminal, the circuit breaker contact temperature and beat the heat map; the use of ultrasonic detector measurement has no spark discharge phenomena.
4. laying low-voltage distribution lines
