断路器合闸线圈静铁芯松动故障的分析处理

Analysis and Solution of the Looseness Fault in Breaker’s Closing Coil Static Iron Core

根据１１０ｋＶＳＦ６断路器的合闸线圈静铁芯松动引起动作时间增加的事故，分析了ＳＦ６断路器合闸线圈静铁芯松动与合闸时间的关系，并提出处理对策和决定依据。

For the reason that the looseness fault in closing coil static iron core of 110kV SF 6 circuit breaker will cause the increasing in starting time,the article describes the relation between the looseness in closing coil static iron core of 110kV SF 6 circuit breaker and closing time,and advances some measures and the basis for solution as well.
