交流接觸器參數(shù)主要由四部分組成:(1) 電磁系統(tǒng),包括吸引線圈、動鐵芯和靜鐵芯；(2)觸頭系統(tǒng),包括三組主觸頭和一至兩組常開、常閉輔助觸頭,它和動鐵芯是連在一起互相聯(lián)動的；(3)滅弧裝置,一般容量較大的交流接觸器都設(shè)有滅弧裝置,以便迅速切斷電弧,免于燒壞主觸頭；(4)絕緣外殼及附件,各種彈簧、傳動機(jī)構(gòu)、短路環(huán)、接線柱等。 工作原理 當(dāng)線圈通電時(shí),靜鐵芯產(chǎn)生電磁吸力,將動鐵芯吸合,由于觸頭系統(tǒng)是與動鐵芯聯(lián)動的,因此動鐵芯帶動三條動觸片同時(shí)動作,主觸點(diǎn)閉合,和主觸點(diǎn)機(jī)械相連的輔助常閉觸點(diǎn)斷開，輔助常開觸點(diǎn)閉合，從而接通電源。當(dāng)線圈斷電時(shí),吸力消失, 動鐵芯聯(lián)動部分依靠彈簧的反作用力而分離,使主觸頭斷開,和主觸點(diǎn)機(jī)械相連的輔助常閉觸點(diǎn)閉合，輔助常開觸點(diǎn)斷開，從而切斷電源。
