摘要

通过对一起处于热备用中的500 kV SF6断路器

因加上工频与拍频电压的矢量差而爆炸的原因分析

提出在500 kV电网的规划设计中

应增加拍频过电压的计算内容。对现有同类500 kV线路

采用先将断路器转为冷备用后

再操作线路对侧断路器的方法

以防止该类事故的发生。

Abstract

Researching on a explosion occurred in a warm stand-by 500 kV SF6 Circuit Breaker

which was caused by the vector differences between the beat frequency voltage and the power frequency voltage

this essay proposed some methods to prevent accidents like that.Firstly

it should be added the calculation of the beat frequency over-voltage

in the planning a designing of 500 kV power grid.Secondly

it was suggested that

the warm standby line circuit breakers should be turn into cold standby before operating the circuit breakers on the other side.
