摘要
通过对一起LW13A-550型GIS断路器防慢分装置损坏变形事件进行分析,发现故障可能为开关控制回路及电机回路失电时强行分合闸或防慢分装置卡涩后分闸导致。针对此次损坏情况,对该类型机构提出了防范措施和建议。
The damage and deformation event of anti-slow switching device for LW13A-550 GIS circuit breaker was analyzed.The reason might be that the switch control circuit and the motor circuit were forcibly closed when the power was lost or the anti-slow switching device was blocked.Several preventive measures and suggestions were proposed for this type of organization.
