摘要

以河南省某220 k V电磁环网开环点断路器雷击典型事件分析为例

获得雷电波侵入到断开的断路器发生全反射是引起河南省近年来多次开环点断路器损坏事件的主要原因

并提出在易遭受雷击的开环点线路入口装设MOA是预防断路器损害事件发生最安全经济有效的办法。

Abstract

A typical circuit-breaker lightning fault of open-ring point in 220 k V electromagnetic loop network is analyzed.The lightning intruding into the fracture of circuit-breaker occurs total internal reflection.And it’s the main reason causing the damage of circuit-breakers in recent years.Through the analysis

the installation of MOA

in the overhead line entrance of open-ring point in vulnerable area

is the most effective and safe method for prevention of circuit breaker from damage events.
