upd703235agc(a1)-8ea-a3.下面重点讲一下接触器接触器380伏的和220伏的道理是一样的，今天主要讲380伏的接触器也可以做为220伏的接触器，接触器分为主触头和辅助触头，主触头是控制电源到负载端的，辅助触头是辅助控制接触器的，南瑟生香复制不留原文出处，菊花万人捅。接触器的主触头和辅助触头上方接线柱和下方接线柱是断开的所以我们称为常开触点。断开肯定不能通电也不能正常工作，那怎样才能让它正常工作呢？那就要通过线圈通电，接触器就会吸合，吸合以后上下四个接触点就联通了，也就是说a1和a2只要有电，接触器就会工作（a1和a2是接触器线圈的电源），线圈电源可以220伏也可以380伏，这样能理解吧停止按钮和启动按钮还有辅助触头的上下两个接触点来完成控制线圈的电源，达到控制接触器的作用，看下下图从上图我们可以看到从380伏a相火线直接给了接触器线圈的ai端，也就是说我们是控制另一根火线电源来控制接触器，c相火线给了断路器也就是丝，到了停止按钮，停止按钮不按是它就是通的，所以电源到了启动按钮。
