摘要

近年来电网中高压断路器遭雷击引起的故障时有发生且成上升趋势。笔者分析了雷击引起的高压断路器故障:故障与断路器本身有一定的关系

但还受到变电站绝缘配合技术原则的影响。探讨了断路器的性能、现行有关标准和规程的适用性

得出解决故障可采取的措施:在断路器的进（出）线侧安装避雷器

如变电站内无安装位置的话

可在线路终端塔上安装带间隙的线路避雷器。

Abstract

Some faults caused by lightning strike on the HV circuit breakers in East China Grid are analyzed

and the results show that the faults depend on not only the structure of circuit breakers

but also the insulation coordination of substation

which exerts more influence on the faults than the former.A method is hence proposed to prevent the fault by setting a surge arrester at inlet（or outlet） side of circuit breaker

or setting a surge arrester with gap at line terminal tower if there isn’t a position for setting the arrester within substation.
