| 摘 要： | 断路器偷跳可能造成严重后果，应予以重视。介绍一起500kV断路器偷跳引起的重合闸反复动作案例，提出了某些情况下偷跳会引起重合闸反复动作、造成断路器周期性跳合类似“跳跃”的现象，详细分析了该现象产生原因及过程，最后提出了能避免重合闸反复动作，加快断路器三相跳闸的解决方案。

| Abstract: | The non-fault trip of circuit breaker may cause serious consequences,so it should be much accounted.A case of repeating reclosing caused by non-fault trip of a 500 kV circuit breaker is introduced.The phenomenon,such as repeating reclosing and periodically tripping and closing of circuit breaker like jumping,are put forward in some cases,which are caused by non-fault trip.The occurring reasons and process of this phenomenon are analyzed in detail.Finally,the solutions are proposed to avoid repeating reclosi... |
