摘　　要：在现场工作中存在着某些原因使得断路器位置反映不正确,并进而经常造成重合闸的误动作。结合一次由于断路器连锁回路的问题而引起的重合闸误动的事件,对这一问题进行了深入彻底的分析,并提出了相应的解决方案。Some kinds of reasons which result in wrong display of swtichgear state may exist in secondary circuit,and it will usually cause maloperation of switchgear reclosure. Such a case of maloperation on reclosure of switchgear due to breaker control ci（cuit fault is found out in this experience of field works, this paper thoroughly researches the fault,and its inherent key cause is worked out. effective solution to solve the existing problem to secondary circuit is provided as well.
