断路器开关合闸线圈烧毁事故产生的原因与解决技巧

On the Causes and Solving Skills of the Accident of Switching the Switching Coil of the Circuit Breaker

在新的时代背景下,随着智能化变电站得到广泛的应用,变电站中绝大部分的二次电缆回路中使用的电缆都由光缆来替代,这样不仅大大节约了成本,还促使二次设备的智能化程度逐渐提高。但是一些一次设备还没有完全智能化,例如:在断路器开关合闸的时候,经常发生不能分合的故障,严重一点甚至造成分合闸线圈出现烧毁现象,此现象会给变电站的运行和检修带来相应的麻烦。基于此,本文主要对解决断路器开关合闸线圈烧毁的技巧进行分析,希望对相关人士有所帮助。

under the background of new era, with the widely application of intelligent substation, substation cable used in the vast majority of the two cable loop in by cable to be replaced, which not only greatly saves the cost, intelligence also prompted the two equipment gradually improve. But some of the primary equipment is not completely intelligent, for example: when the circuit breaker switching, fault can be divided into the frequent, serious and even cause a closing coil burning phenomenon occurred, this phenomenon will lead to the operation and maintenance of substation bring trouble. Based on this, this paper mainly analyzes the technique of breaking the switching coils of the circuit breaker, and hopes to help the related people.
