电气火灾是指由电气原因引发燃烧而造成的灾害。短路、过载、漏电等电气事故都有可能导致火灾。设备自身缺陷、施工安装不当、电气接触不良、雷击静电引起的高温、电弧和电火花是导致电气火灾的直接原因,周围存放易燃易爆物是电气火灾的环境条件。电气火灾产生的主要原因有:(1)设备或线路发生短路故障。电气设备由于绝缘损坏、电路年久失修、疏忽大意、操作失误及设备安装不合格等将造成短路故障,其短路电流可达正常电流的几十倍甚
Electrical fire refers to the disaster caused by the electrical cause of combustion. Electrical short-circuits, overloads, earth leakage and other electrical accidents may result in fire. Equipment itself defects, improper construction and installation, poor electrical contact, lightning caused by high temperature, arc and sparks are the direct cause of electrical fire, surrounded by flammable and explosive material is an electrical fire environmental conditions. The main causes of electrical fire are: (1) equipment or line short circuit fault. Electrical equipment as a result of insulation damage, the circuit disrepair, carelessness, operating errors and equipment installation will result in short circuit failure, the short circuit current up to several times the normal current
