摘要
分析研究一起起重机触电原因。采用低压(不大于50 V)控制来解决触电,主要有SELV、PELV、FEL系统。通过采用低压(不大于50 V)控制方法,切实解决了起重机触电的问题。采用特低电压(ELV)为手电门供电,安全有效,是解决该问题的好办法。
To analyze the causes of crane electric mainly SELV, PELV, FEL system, through the use shock.Using low of low pressure （less than 50 V）control to solve the electric shock, （no more than 50 V）control, and effectively solve the problem of electric shock of the crane, the use of extra low voltage （ELV）for the flashlight door power supply, safe and effective to solve the problem, is a good way to.
