合后继在重合闸中的作用分析

Analysis on the role of subsequent Reclosing

合后继（简称KKJ或HHJ）在重合闸的逻辑中占有非常重要的的地位，对于控制回路中没有合后继的装置，在综自改造时若不妥善解决将会使重合闸的动作逻辑出现错误，造成错误的重合闸出现非预期重合闸。

In the subsequent （KKJ or HHJ） in subsequent device without closing the control loop, reclosing logic occupies a very important position, for the the alteration if not properly resolved will make the action logic of reclosing errors, errors caused by reclosing of unexpected reclosure.
