施耐德交流接觸器湖南總代理，施耐德湖南一級(jí)代理商-長(zhǎng)沙江業(yè)電氣設(shè)備有限公司！ 24小時(shí)熱線(xiàn)18229710492(南湖機(jī)電大市場(chǎng)旁）

? ? ? 施耐德接觸器是用來(lái)控制一次電路的，施耐德接觸器一般是工業(yè)用品，家里生活中一般用不到施耐德接觸器，施耐德接觸器是指工業(yè)電中利用線(xiàn)圈流過(guò)電流產(chǎn)生磁場(chǎng)，使觸頭閉合，以達(dá)到控制負(fù)載的電器。施耐德接觸器由電磁系統(tǒng)、觸頭系統(tǒng)和滅弧裝置組成。其原理是當(dāng)接觸器的電磁線(xiàn)圈通電后，會(huì)產(chǎn)生很強(qiáng)的磁場(chǎng)，使靜鐵心產(chǎn)生電磁吸力吸引銜鐵，并帶動(dòng)觸頭動(dòng)作：常閉觸頭斷開(kāi)；常開(kāi)觸頭閉合，兩者是聯(lián)動(dòng)的。當(dāng)線(xiàn)圈斷電時(shí)，電磁吸力消失，銜鐵在釋放彈簧的作用下釋放，使觸頭復(fù)原：常閉觸頭閉合；常開(kāi)觸頭斷開(kāi)。
