低压配电盘(箱)是线路的重要组成部分,由盘板、开关、熔断器、电气仪表等组成.由于人们对它的火灾危险性不甚了解、疏于防范,常发生火灾.引起低压配电盘着火的常见原因有:一是布线零乱、接触不良、绝缘导线受潮,开关、电气仪表等选择不当,便会产生短路、接触电阻过大、过负荷引起火灾;二是没有根据用电量的多少,选用合适的熔断器,甚至用铁丝、铜丝代替,一旦过负荷便会引起火灾;三是长期不检修、不清扫,甚至在配电盘下面堆放可燃 Low-voltage switchboard (box) is an important part of the circuit composed of a plate, switches, fuses, electrical instruments, etc. Because of its fire risk is not well understood, negligent prevention, often a fire. Caused by low voltage switchboard fire Common causes are: First, the wiring disorder, poor contact, damp insulated wire, switches, electrical instruments and other improper choice, it will produce short circuit, contact resistance is too large, overload caused by fire; second is not based on the amount of electricity consumption, Use the appropriate fuse, or even wire, copper wire instead, once the overload will cause a fire; Third, long-term maintenance, cleaning, or even stacked below the switchgear combustible
