摘　　要：小接点关联大保护,刀闸辅助接点经常出现接触不良、粘连、转换不良、抖动等现象。变电站投入运行6a以来,220k V室外刀闸倒闸操作中,辅助接点频繁出现问题,这给设备的倒闸操作及系统的稳定运行带来影响。现根据两个案例分析刀闸辅助接点转换不良问题对系统的影响。Small junction correlates large protection, disconnecting auxiliary contact appears loose contorted, sticky, poor transform and shaking frequently. In outdoor disconnecting switching operation of 220kV, auxiliary contact appears problem repeatedly since the transformer substation was put into operation six years ago, which takes great influence on switching operation of equipment and stable operation of system. Now, analyz- ing the influence on system that caused by poor transform problems of disconnecting auxiliary contact according to two cases.
