建筑網片廠家(jia)介紹電力拖動系統。

      電(dian)力推動(dong)(dong)系統是(shi)為電(dian)梯運行(xing)提供(gong)動(dong)(dong)力、進行(xing)電(dian)梯控制的系統，由以(yi)下兒部分組成:1曳(ye)引電(dian)動(dong)(dong)機 是(shi)電(dian)梯的動(dong)(dong)力源，有交流(liu)電(dian)動(dong)(dong)機和直流(liu)電(dian)動(dong)(dong)機兩種。

      供(gong)電(dian)(dian)(dian)(dian)系(xi)統是為電(dian)(dian)(dian)(dian)梯的(de)(de)(de)電(dian)(dian)(dian)(dian)機提供(gong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)裝置。 電(dian)(dian)(dian)(dian)梯一般應(ying)有專用回路供(gong)電(dian)(dian)(dian)(dian)，每臺電(dian)(dian)(dian)(dian)梯應(ying)裝設單獨(du)的(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)開(kai)關和保(bao)護裝置，開(kai)關應(ying)安裝在機房內便于操作(zuo)和維(wei)修(xiu)的(de)(de)(de)地方(fang)。各(ge)種電(dian)(dian)(dian)(dian)梯的(de)(de)(de)供(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓都是380V三相(xiang)交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)，直流(liu)(liu)電(dian)(dian)(dian)(dian)梯是由(you)(you)交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)向直流(liu)(liu)發(fa)電(dian)(dian)(dian)(dian)機組供(gong)電(dian)(dian)(dian)(dian)，再(zai)由(you)(you)直流(liu)(liu)發(fa)電(dian)(dian)(dian)(dian)機組向直流(liu)(liu)牽引電(dian)(dian)(dian)(dian)動(dong)機供(gong)電(dian)(dian)(dian)(dian);或由(you)(you)交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)經可控硅整(zheng)流(liu)(liu)成直流(liu)(liu)，再(zai)向直流(liu)(liu)牽引電(dian)(dian)(dian)(dian)動(dong)機供(gong)電(dian)(dian)(dian)(dian)。除了(le)作(zuo)為動(dong)力的(de)(de)(de)三相(xiang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)以外，還應(ying)有單相(xiang)照明用電(dian)(dian)(dian)(dian)，故要求電(dian)(dian)(dian)(dian)梯的(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)線(xian)(xian)(xian)中(zhong)應(ying)有工(gong)作(zuo)零線(xian)(xian)(xian)，即采(cai)用三線(xian)(xian)(xian)四線(xian)(xian)(xian)制供(gong)電(dian)(dian)(dian)(dian)或三相(xiang)五線(xian)(xian)(xian)制供(gong)電(dian)(dian)(dian)(dian)。民(min)，消技(ji)水出
