摘要
针对某变电站220 kV GIS断路器合闸时间及不同期时间严重超标、合闸速度偏低问题,通过对设备异常现象进行剖析,结合现场验证,准确找到GIS断路器合闸机械特性异常原因;同时,根据现场实践经验,提出了运维检修预防性措施,为类似结构GIS断路器的运行维护提供参考。
Aiming at the problems that the closing time and asynchronization time are seriously exceeded the standard and the low closing speed of a 220 kV GIS circuit-breaker in a substation,through the analysis of the failure phenomenon and the field verification,the abnormal reasons of mechanical characteristics of GIS circuit-breaker are found out accurately.Meanwhile,based on the field experiences,the preventive measures for operation and maintenance are put forward,which provides a reference for the operation and maintenance of similar GIS circuit-breakers.
