中国狼群在线资源WWW官网电器说说断路器和接触器的区别

2021/1/27 14:31:38点击:
区别非常大
断路器是起保护作用的,能熄灭电弧,有分段能力。接触器是利用线圈来控制电路的通断,接触器通电后,常开的就闭上了,长闭的打开,这样来控制。
  1、断路器主要做保护,它的保护目前比较常用的是三段保护,既过载保护、短路短延时、短路长延时。还有一些欠压、过压等保护功能。具体视品牌、型号而定。它的分合闸可以手动也可电动。安装方式有固定式、抽屉式等。根据电流的大小和工作电压的等级可以分多种
  2、接触器主要做工业控制用,一般负载电机居多,当然会有一些加热器、做双电源切换等场合使用。在接触器的通断是通过控制线圈电压来实现的。根据灭弧的不同结构可以分为真空接触器和普通接触器。根据不同的控制电压可以分为直流接触器交流接触器,它的主要附件辅助触点
好像是这样的
