电气设备“放炮”,是指电气设备因故障等原因所引起的瞬间短路现象。由此造成的设备或配电设施损坏及操作人员烧伤等事故屡见不鲜。那么,如何预防和避免电气设备这种“放炮”现象,保证设备和人身的安全呢? (1)定期巡查和检修电气设施,消除电气设备内部故障及隐患。 (2)岗位人员或电工合电气开关时,对起动大容量负载不能直接合闸运行,应用按钮操作,停运大容量负载时不能直接拽隔离开关,应先停按钮。 (3)在日常检修维护工作时,对电气线路的接头、封口要有足够的绝缘强度,要防潮湿、耐磨损,对新安装线路和检修的线路要用
Electrical equipment “blasting”, refers to the electrical equipment due to failure and other causes of short-circuit phenomenon. The resulting equipment or power distribution facilities and operator burns accidents are common. So, how to prevent and avoid the phenomenon of “blasting” of electrical equipment to ensure the safety of equipment and people? (1) Regular inspection and overhaul of electrical facilities to eliminate internal faults and hidden dangers of electrical equipment. (2) When the position staff or the electricians switch on the electric switch, it can not directly close the starting large capacity load and apply the button operation. When disconnecting the large capacity load, the isolating switch should not be dragged directly. Stop the button first. (3) In the routine maintenance and repair work, the electrical connections, seals have sufficient dielectric strength, to prevent moisture, wear-resistant, the new installation of lines and maintenance lines to use
