摘　　要：针对一起220kV线路试运行前保护传动,模拟开关偷跳重合闸动作这一功能时发现重合闸不动作的情况,分析开关操作机构和重合闸回路,查找出具体原因并成功制定出改进方案,并在现场运行中成功实施。There is a case that the switch ofa 220kV transmission line refused to reclose when switch secret trip has been found while checking the new line protect circuit. This paper analyzes the switch operation mechanism and the recloser circuit, finds the reason and improves the recloser circuit based on the actual production.
