特點

永(yong)磁(ci)交流接觸器(qi)的(de)(de)革(ge)新技術特點(dian)是用(yong)永(yong)磁(ci)式驅動機(ji)構(gou)取代了(le)傳統(tong)的(de)(de)電(dian)(dian)(dian)(dian)磁(ci)鐵驅動機(ji)構(gou),即利用(yong)磁(ci)鐵與微電(dian)(dian)(dian)(dian)子模(mo)塊組成的(de)(de)控(kong)制(zhi)裝置(zhi)(zhi),置(zhi)(zhi)換(huan)了(le)傳統(tong)產品中的(de)(de)電(dian)(dian)(dian)(dian)磁(ci)裝置(zhi)(zhi),運行(xing)中無工作(zuo)電(dian)(dian)(dian)(dian)流,僅由微弱(ruo)信號電(dian)(dian)(dian)(dian)流(0.8-1.5mA)。微電(dian)(dian)(dian)(dian)子模(mo)塊中包含六個(ge)基本的(de)(de)部(bu)(bu)分(fen)：1.電(dian)(dian)(dian)(dian)源(yuan)整(zheng)流; 2.控(kong)制(zhi)電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)壓實時檢測(ce); 3.釋(shi)放儲(chu)能(有的(de)(de)也有吸合(he)儲(chu)能,但不是必(bi)須有); 4.儲(chu)能電(dian)(dian)(dian)(dian)容(rong)電(dian)(dian)(dian)(dian)壓檢測(ce); 5.抗干擾(rao)門檻電(dian)(dian)(dian)(dian)壓檢測(ce);6.釋(shi)放邏輯(ji)電(dian)(dian)(dian)(dian)路。這(zhe)6部(bu)(bu)分(fen)是永(yong)磁(ci)操(cao)作(zuo)機(ji)構(gou)電(dian)(dian)(dian)(dian)子控(kong)制(zhi)部(bu)(bu)分(fen)的(de)(de)必(bi)要組成,如果缺少任何一個(ge)部(bu)(bu)分(fen),操(cao)作(zuo)機(ji)構(gou)在(zai)特定的(de)(de)情(qing)況下就沒法正常工作(zuo)。這(zhe)6個(ge)部(bu)(bu)分(fen),也就決定了(le)操(cao)作(zuo)機(ji)構(gou)可以具備抗晃(huang)電(dian)(dian)(dian)(dian)功能。
