Discussion on Fault Finding Method of Control Circuit of High Voltage Switchgear

Wang Meng

[Abstract]As a bridge connecting the primary system and secondary system of the power grid, the control circuit of the high-voltage switchgear plays an important role. When it fails, the operation and maintenance personnel must correctly and timely judge the nature of the fault, analyze and deal with the accident quickly and orderly, improve the accident handling speed and work efficiency, and effectively prevent the occurrence and expansion of electrical accidents, so as to avoid the power failure of the substation, Bring disastrous consequences to people’s lives or industrial and mining enterprises.
