建筑(zhu)網片廠(chang)家介紹電力拖(tuo)動系統。

      電(dian)(dian)力(li)(li)推動系(xi)統是為電(dian)(dian)梯運行提供動力(li)(li)、進行電(dian)(dian)梯控制(zhi)的(de)系(xi)統，由以(yi)下兒部分組成:1曳引電(dian)(dian)動機 是電(dian)(dian)梯的(de)動力(li)(li)源，有(you)交流電(dian)(dian)動機和(he)直流電(dian)(dian)動機兩種。

      供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系統是為電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)(de)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)提供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)裝置。 電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)一般應(ying)(ying)有(you)(you)專用回(hui)路(lu)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)，每(mei)臺電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)應(ying)(ying)裝設單獨的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)開(kai)關和保護裝置，開(kai)關應(ying)(ying)安(an)裝在機(ji)(ji)(ji)房內便于操作(zuo)和維修的(de)(de)地方。各種電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)(de)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)都是380V三(san)相(xiang)交流電(dian)(dian)(dian)(dian)(dian)，直流電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)是由交流電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)向(xiang)直流發電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)組供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)，再由直流發電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)組向(xiang)直流牽引電(dian)(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian);或(huo)由交流電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)經可控硅整流成直流，再向(xiang)直流牽引電(dian)(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。除(chu)了作(zuo)為動力的(de)(de)三(san)相(xiang)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)以(yi)外，還應(ying)(ying)有(you)(you)單相(xiang)照明用電(dian)(dian)(dian)(dian)(dian)，故要求電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)線(xian)(xian)(xian)中應(ying)(ying)有(you)(you)工作(zuo)零線(xian)(xian)(xian)，即采用三(san)線(xian)(xian)(xian)四線(xian)(xian)(xian)制(zhi)(zhi)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)或(huo)三(san)相(xiang)五(wu)線(xian)(xian)(xian)制(zhi)(zhi)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。民，消技水出

      電氣控制系統速度反饋裝置和電動機調速裝置 起對曳引電動機進行調速的作用，建筑網片廠(chang)家(jia)介(jie)紹電力拖(tuo)動(dong)系統。

      電(dian)梯(ti)的(de)電(dian)氣(qi)控制(zhi)系(xi)(xi)統(tong)的(de)種類很多，可以按其控制(zhi)電(dian)氣(qi)控制(zhi)系(xi)(xi)統(tong)是(shi)電(dian)梯(ti)各(ge)系(xi)(xi)統(tong)中(zhong)較重要系(xi)(xi)統(tong)之一，方(fang)式(shi)分(fen)為手柄(bing)操作(zuo)控制(zhi)系(xi)(xi)統(tong)、 按鈕控制(zhi)系(xi)(xi)它(ta)決定著電(dian)梯(ti)的(de)性能和自(zi)動(dong)化程度，建(jian)筑網片(pian)廠家介紹電(dian)力拖動(dong)系(xi)(xi)統(tong)。
