同期装置选线器受干扰造成断路器误合原因分析

Cause Analysis on the Falsely Closing Circuit Breaker Disturbed Synchronization Device's Line - selector

介绍了由于同期装置选线器受到反电势干扰造成在合某一断路器时,误合其他断路器的事故,分析了断路器误合原因,详述了试验验证过程,提出了改进意见。

This paper introduces an accident that other circuit breaker falsely close when closing a certain circuit breaker because sychronization device＇s line - selector is disturbed by reverse voltage. It also analyses the reason of falsely closing circuit breaker and introduces the process of proving the reason through experiment in detail and advances some improved advice.
