继电保护装置电源插件失效应对措施

Countermeasures for Failure of Power Supply Plug in Relay Protection Equipment

继电保护装置对电网的稳定运行起到了关键作用,而电压插件失效是继电保护装置运行不稳定的主要原因。本文通过对电源插件失效情况、工作原理及电解电容关键元件失效成因进行研究,提出电源插件失效的应对措施。

Relay Protection Equipment plays a key role in the stable operation of power grid,and the failure of voltage plug-in is the main reason for the unstable operation of relay protection equipment.This paper studies the failure situation,working principle and failure causes of key components of electrolytic capacitor,and put forward the countermeasures for the failure of power plug-in.
