在矿山采制设备上用真空接触器取代少油断路器，体积小、重量轻及三相触点免维修、整体更换方便，从而减少维修工作量、提高生产率被广泛地应用在矿山电动挖掘机原动机的启动回路中。我矿的WK-4型、EK-4型、WK-10A型、WK-10B型原动机的启动接触器都是采用的ZN-6型真空接触器，总结其长期使用的经验，对其易出故障的几个部位提出几点看法，以供维修人员借鉴参考。
In mine mining equipment with vacuum contactor to replace less oil circuit breakers, small size, light weight and three-phase contact-free maintenance, the overall replacement of convenience, thereby reducing maintenance workload and increase productivity is widely used in mining electric excavator Motivation of the starting circuit. I mine mine WK-4 type, EK-4 type, WK-10A type, WK-10B type of prime mover starter contactors are used ZN-6 type vacuum contactor, summing up its long-term experience, its easy Several parts of the fault put forward a few comments for maintenance personnel for reference.
