断路器“控制回路断线”异常分析

Analysis on Anomalous Breakage in Breaker-controlled Loop

主要对一起10kV线路事故跳闸，重合不成，同时监控系统发出该断路器”控制回路断线”信号的异常现象进行分析处理，并结合叫空制回路断线”发出的原理，分析了日常运行中出现断路器”控制回路断线”告警的各种因素及处理方法，为电网的安全运行提供工作参考，有利于整个电网的安全稳定运行。

This paper, forcusing on an anomaly that the line is failed to reclose after a 10 kV-line trip accident and that the monitoring system sends a signal indicating there is a breakage occurred in this breaker-controlled loop, analyzes the reasons for and the treatment of breakage warnings occuring in switch-controlled loops, in hope of providing references for the sound operation of the whole grid.
