建筑(zhu)網(wang)片(pian)廠家(jia)介紹電力拖(tuo)動系統。

      電(dian)(dian)(dian)(dian)力(li)推動(dong)(dong)(dong)系統(tong)是為電(dian)(dian)(dian)(dian)梯運行(xing)提供動(dong)(dong)(dong)力(li)、進行(xing)電(dian)(dian)(dian)(dian)梯控制(zhi)的系統(tong)，由以下兒(er)部(bu)分組成:1曳引電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji) 是電(dian)(dian)(dian)(dian)梯的動(dong)(dong)(dong)力(li)源，有(you)交流電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)和直流電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)兩種。

      供電(dian)(dian)(dian)(dian)(dian)系統是為電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)提供電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)裝置。 電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)一般應(ying)(ying)有專用(yong)回路供電(dian)(dian)(dian)(dian)(dian)，每臺電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)應(ying)(ying)裝設單獨(du)的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)開關(guan)和保護裝置，開關(guan)應(ying)(ying)安裝在機(ji)(ji)(ji)房(fang)內便于操作(zuo)和維修(xiu)的(de)地方(fang)。各種電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓都是380V三相(xiang)交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)是由交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)向(xiang)直(zhi)流(liu)(liu)發電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)組供電(dian)(dian)(dian)(dian)(dian)，再由直(zhi)流(liu)(liu)發電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)組向(xiang)直(zhi)流(liu)(liu)牽引(yin)(yin)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)供電(dian)(dian)(dian)(dian)(dian);或由交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)經可控硅整流(liu)(liu)成直(zhi)流(liu)(liu)，再向(xiang)直(zhi)流(liu)(liu)牽引(yin)(yin)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)供電(dian)(dian)(dian)(dian)(dian)。除了作(zuo)為動(dong)力的(de)三相(xiang)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)以(yi)外，還應(ying)(ying)有單相(xiang)照(zhao)明(ming)用(yong)電(dian)(dian)(dian)(dian)(dian)，故(gu)要求電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)線(xian)(xian)中應(ying)(ying)有工(gong)作(zuo)零線(xian)(xian)，即采用(yong)三線(xian)(xian)四線(xian)(xian)制供電(dian)(dian)(dian)(dian)(dian)或三相(xiang)五線(xian)(xian)制供電(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，建筑網片廠家(jia)介紹電(dian)力拖動系統。

      電(dian)(dian)(dian)梯(ti)(ti)的電(dian)(dian)(dian)氣控(kong)制(zhi)(zhi)系(xi)統的種(zhong)類很多，可以按(an)其(qi)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)氣控(kong)制(zhi)(zhi)系(xi)統是電(dian)(dian)(dian)梯(ti)(ti)各系(xi)統中較重要系(xi)統之一，方(fang)式分為手(shou)柄操作控(kong)制(zhi)(zhi)系(xi)統、 按(an)鈕控(kong)制(zhi)(zhi)系(xi)它決定著電(dian)(dian)(dian)梯(ti)(ti)的性能(neng)和自動化程度，建筑網片廠家介紹(shao)電(dian)(dian)(dian)力拖動系(xi)統。
