摘要
结合同一升压站内6台断路器的检修情况,通过对比触头的烧损度、保护故障记录等信息对其中两台烧损较为严重的断路器进行原因分析。最后,对同类型GIS开盖检修的周期和规模提出了一些建议。
Based on maintenance information of six circuit breakers in a voltage booster station,the cause of two seriously spark worn breakers were analyzed by comparing their burning loss of contacts and protection fault records.Finally,suggestions were put forward on the cycle and scale of cover-opening maintenance of this e type of GIS.
