摘　　要：变电所电磁锁是一种防止高压设备误操作的电控机构联锁装置,但在近些年地铁实际运行维护中,负极柜刀闸电磁锁多次发生了线圈烧毁现象。文章结合南京地铁3号线、宁天线的实际运行维护情况,分析了负极刀闸电磁锁故障的原因,并提出了解决方案,以期为相关人员提供参考。The electromagnetic lock of the substation is an interlocking device of the electrical control mechanism to prevent the misoperation of high-voltage equipment.However,in recent years,the negative cabinet knife switch electromagnetic lock has repeatedly experienced coil burnout in the actual operation and maintenance of the subway.The article combines the actual operation and maintenance situation of Nanjing Metro Line 3 and Ning Antenna to analyze the causes of the fault of the negative pole knife switch electromagnetic lock,and proposes a solution to provide reference for relevant personnel.
