建筑網片廠家介(jie)紹電力拖動系統。

     ; 電(dian)(dian)力推動系統是(shi)為(wei)電(dian)(dian)梯運行提供動力、進行電(dian)(dian)梯控制(zhi)的系統，由以下兒部分(fen)組成:1曳引電(dian)(dian)動機 是(shi)電(dian)(dian)梯的動力源，有交(jiao)流電(dian)(dian)動機和直(zhi)流電(dian)(dian)動機兩種。

      供(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)是為電(dian)(dian)(dian)(dian)(dian)梯(ti)的電(dian)(dian)(dian)(dian)(dian)機(ji)提供(gong)電(dian)(dian)(dian)(dian)(dian)源的裝置。 電(dian)(dian)(dian)(dian)(dian)梯(ti)一般(ban)應(ying)(ying)有專用回路供(gong)電(dian)(dian)(dian)(dian)(dian)，每(mei)臺電(dian)(dian)(dian)(dian)(dian)梯(ti)應(ying)(ying)裝設單獨的電(dian)(dian)(dian)(dian)(dian)源開(kai)關和保護(hu)裝置，開(kai)關應(ying)(ying)安裝在機(ji)房內便于(yu)操作(zuo)(zuo)和維修的地方。各(ge)種(zhong)電(dian)(dian)(dian)(dian)(dian)梯(ti)的供(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓都是380V三(san)(san)相(xiang)交流(liu)電(dian)(dian)(dian)(dian)(dian)，直流(liu)電(dian)(dian)(dian)(dian)(dian)梯(ti)是由(you)(you)交流(liu)電(dian)(dian)(dian)(dian)(dian)源向直流(liu)發電(dian)(dian)(dian)(dian)(dian)機(ji)組供(gong)電(dian)(dian)(dian)(dian)(dian)，再由(you)(you)直流(liu)發電(dian)(dian)(dian)(dian)(dian)機(ji)組向直流(liu)牽引(yin)電(dian)(dian)(dian)(dian)(dian)動機(ji)供(gong)電(dian)(dian)(dian)(dian)(dian);或由(you)(you)交流(liu)電(dian)(dian)(dian)(dian)(dian)源經可(ke)控硅整流(liu)成直流(liu)，再向直流(liu)牽引(yin)電(dian)(dian)(dian)(dian)(dian)動機(ji)供(gong)電(dian)(dian)(dian)(dian)(dian)。除了作(zuo)(zuo)為動力的三(san)(san)相(xiang)電(dian)(dian)(dian)(dian)(dian)源以外(wai)，還應(ying)(ying)有單相(xiang)照明(ming)用電(dian)(dian)(dian)(dian)(dian)，故要求電(dian)(dian)(dian)(dian)(dian)梯(ti)的電(dian)(dian)(dian)(dian)(dian)源線中應(ying)(ying)有工作(zuo)(zuo)零線，即采用三(san)(san)線四線制(zhi)供(gong)電(dian)(dian)(dian)(dian)(dian)或三(san)(san)相(xiang)五線制(zhi)供(gong)電(dian)(dian)(dian)(dian)(dian)。民，消技水出(chu)
