摘要
通过对一起GIS的隔离开关合闸操作机构由于合闸不到位引起的拉弧故障的处理和原因分析,建议GIS中隔离开关操作机构选用气动或弹簧机构,并在断路器合闸控制回路增加隔离开关合闸到位检测联锁信号。
By treatment and analysis of arc fault caused by the closing operation mechanism of a GIS isolator under position,it is suggested that the isolator operation mechanism in GIS uses pneumatic or spring mechanism and adds isolator closing position detection linterlocking signal in the closing control loop of the circuit breaker.
