摘　　要：某220 kV变电站的某220kV线路合后继电器(HHJ)和跳位继电器(TWJ)位置不一致,导致2条220 kV线路先后发生信号误发和重合闸误动作。从事故现象、动作原理等方面探讨发生误动作的原因,并提出合理的应对措施和改进方法。For a 220 kV line in a 220 kV substation,the positions of the post closing relay(HHJ)and the tripping relay(TWJ)are inconsistent,resulting in two 220 kV Lines'signal missending and reclosing misoperation successively.The causes of malfunction are discussed from the aspects of accident phenomena and action principle,and reasonable countermeasures and improvement methods are put forward.
