建筑(zhu)網片廠家介紹電力拖動系統(tong)。

      電(dian)力(li)推動系(xi)統是為電(dian)梯(ti)運行提供動力(li)、進行電(dian)梯(ti)控制的系(xi)統，由(you)以下兒部分組成(cheng):1曳(ye)引電(dian)動機 是電(dian)梯(ti)的動力(li)源，有交流電(dian)動機和直流電(dian)動機兩種。

      供(gong)(gong)電(dian)(dian)(dian)(dian)系(xi)統是(shi)為(wei)電(dian)(dian)(dian)(dian)梯(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)機(ji)(ji)提供(gong)(gong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)裝置。 電(dian)(dian)(dian)(dian)梯(ti)一般應(ying)有專用(yong)回(hui)路供(gong)(gong)電(dian)(dian)(dian)(dian)，每臺電(dian)(dian)(dian)(dian)梯(ti)應(ying)裝設單獨的(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)開關(guan)和保護(hu)裝置，開關(guan)應(ying)安裝在機(ji)(ji)房內便于操作(zuo)和維(wei)修的(de)(de)(de)地方(fang)。各種電(dian)(dian)(dian)(dian)梯(ti)的(de)(de)(de)供(gong)(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓都(dou)是(shi)380V三(san)(san)相(xiang)交(jiao)流(liu)電(dian)(dian)(dian)(dian)，直(zhi)流(liu)電(dian)(dian)(dian)(dian)梯(ti)是(shi)由交(jiao)流(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)向(xiang)直(zhi)流(liu)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)組供(gong)(gong)電(dian)(dian)(dian)(dian)，再由直(zhi)流(liu)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)組向(xiang)直(zhi)流(liu)牽(qian)引電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian);或(huo)由交(jiao)流(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)經可控硅整流(liu)成直(zhi)流(liu)，再向(xiang)直(zhi)流(liu)牽(qian)引電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)。除了作(zuo)為(wei)動(dong)(dong)力的(de)(de)(de)三(san)(san)相(xiang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)以外，還應(ying)有單相(xiang)照明用(yong)電(dian)(dian)(dian)(dian)，故要求(qiu)電(dian)(dian)(dian)(dian)梯(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)線(xian)中應(ying)有工作(zuo)零(ling)線(xian)，即(ji)采用(yong)三(san)(san)線(xian)四線(xian)制供(gong)(gong)電(dian)(dian)(dian)(dian)或(huo)三(san)(san)相(xiang)五線(xian)制供(gong)(gong)電(dian)(dian)(dian)(dian)。民，消技(ji)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)家介紹電力拖動(dong)系統。

      電(dian)梯(ti)(ti)的電(dian)氣控制系(xi)統(tong)的種類很多，可以按(an)(an)其控制電(dian)氣控制系(xi)統(tong)是電(dian)梯(ti)(ti)各系(xi)統(tong)中較重(zhong)要(yao)系(xi)統(tong)之一，方(fang)式分為(wei)手柄(bing)操作控制系(xi)統(tong)、 按(an)(an)鈕控制系(xi)它決定著電(dian)梯(ti)(ti)的性能和自動(dong)化程(cheng)度，建筑(zhu)網(wang)片廠(chang)家介(jie)紹電(dian)力拖(tuo)動(dong)系(xi)統(tong)。
