摘　　要：针对真空接触器与微机保护装置配合中存在的问题,对故障原因进行了分析,提出了相应的处理对策。结合实际情况,综合考虑后采用取消经济电阻、辅助继电器线圈并联电阻的方案,解决微机保护装置与真空接触器控制回路配合的问题。In view of the problems existing in the coordination between vacuum contactor and microcomputer protective device,this paper analyzes the fault cause,and puts forward the corresponding countermeasures.Based on the actual situation,after comprehensive consideration,a scheme of eliminating the economy resistance and connecting the auxiliary relay coil in parallel with resistance is used to solve the coordinating problem between microcomputer protective device and vacuum contactor control circuit.
