摘要
详细介绍了一起变电站内一台110kV断路器电动拒绝分闸的分析与处理过程,从故障断路器的事故象征入手,通过介绍详细的检查过程,找出了故障断路器电动拒绝分闸的原因,简要说明了维修方法,提出了防止发生类似故障的防范措施,积累了断路器现场运行维护工作的经验,可为其他变电站内不再发生类似的故障提供一定的借鉴作用。
Analysis and processing of an electricity-driven switch-off failure of 110 k V circuit breaker is introduced in detail.Start from the failure symbol,the cause of the switch-off failure is found out through detailed examine.The maintenance method is described briefly,and the measures to prevent the occurrence of similar failure is proposed.The operation and maintenance experience gathered from this failure can provide reference for other substations to prevent similar failures.
