摘　　要：介绍远方跳闸保护功能和动作逻辑,分析了220 kV线路合环时向对侧500 kV变电站误发"远方跳闸"动作信号,造成对侧开关跳闸事件的原因,查找出错误的接线,并对验收过程提出了整改措施及对策,防止同类事件再次发生。This paper introduces the functions and action logic of remote tripping,analyzes the causes of incident that a false"remote trip"action signal is received by 500 kV substation in the opposite side when the 220 kV line is closed,which causes the tripping of opposite switch,it finds out the error wiring and finally puts forward the corrective actions and countermeasures to avoid the recurrence of similar accidents.

关 键 词：远方跳闸 合环 闭锁合闸 误接线
