建筑網片(pian)廠家介(jie)紹電(dian)力拖動系統。

      電力推動(dong)系統是為電梯(ti)運行提供動(dong)力、進行電梯(ti)控制的系統，由(you)以下兒(er)部分(fen)組成:1曳引電動(dong)機(ji) 是電梯(ti)的動(dong)力源，有交流(liu)電動(dong)機(ji)和直流(liu)電動(dong)機(ji)兩種。

      供電(dian)(dian)(dian)(dian)系(xi)統是為電(dian)(dian)(dian)(dian)梯的(de)電(dian)(dian)(dian)(dian)機(ji)提供電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)裝(zhuang)置(zhi)(zhi)。 電(dian)(dian)(dian)(dian)梯一般應有專用回(hui)路供電(dian)(dian)(dian)(dian)，每(mei)臺電(dian)(dian)(dian)(dian)梯應裝(zhuang)設單獨的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開(kai)關和(he)保護裝(zhuang)置(zhi)(zhi)，開(kai)關應安裝(zhuang)在(zai)機(ji)房(fang)內便于(yu)操作(zuo)和(he)維修的(de)地方。各種電(dian)(dian)(dian)(dian)梯的(de)供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)都是380V三相交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)梯是由交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)向直(zhi)流(liu)(liu)(liu)發電(dian)(dian)(dian)(dian)機(ji)組供電(dian)(dian)(dian)(dian)，再(zai)由直(zhi)流(liu)(liu)(liu)發電(dian)(dian)(dian)(dian)機(ji)組向直(zhi)流(liu)(liu)(liu)牽引電(dian)(dian)(dian)(dian)動機(ji)供電(dian)(dian)(dian)(dian);或(huo)由交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)經(jing)可控硅整流(liu)(liu)(liu)成直(zhi)流(liu)(liu)(liu)，再(zai)向直(zhi)流(liu)(liu)(liu)牽引電(dian)(dian)(dian)(dian)動機(ji)供電(dian)(dian)(dian)(dian)。除了(le)作(zuo)為動力的(de)三相電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)以外，還應有單相照明用電(dian)(dian)(dian)(dian)，故要(yao)求電(dian)(dian)(dian)(dian)梯的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)線(xian)中應有工作(zuo)零線(xian)，即采用三線(xian)四線(xian)制(zhi)(zhi)供電(dian)(dian)(dian)(dian)或(huo)三相五線(xian)制(zhi)(zhi)供電(dian)(dian)(dian)(dian)。民(min)，消技水出
