交流施耐德接触器是广泛用作电力的开断和控制电路。它利用主接点来开闭电路,用辅助接点来执行控制指令。主接点一般只有常开接点,而辅助接点常有两对具有常开和常闭功能的接点,小型的施耐德接触器也经常作为中间继电器配合主电路使用。 交流施耐德接触器的接点,由银钨合金制成,具有良好的导电性和耐高温烧蚀性。
一、基本组成
交流施耐德接触器主要有四部分组成:(1) 电磁系统,包括吸引线圈、动铁芯和静铁芯;(2)触头系统,包括三组主触头和一至两组常开、常闭辅助触头,它和动铁芯是连在一起互相联动的;(3)灭弧装置,一般容量较大的交流施耐德接触器都设有灭弧装置,以便迅速切断电弧,免于烧坏主触头;(4)绝缘外壳及附件,各种弹簧、传动机构、短路环、接线柱等。
二、工作原理
当线圈通电时,静铁芯产生电磁吸力,将动铁芯吸合,由于触头系统是与动铁芯联动的,因此动铁芯带动三条动触片同时运行,触点闭合,从而接通电源。当线圈断电时,吸力消失, 动铁芯联动部分依靠弹簧的反作用力而分离,使主触头断开,切断电源。
