建筑網(wang)片廠家介(jie)紹電(dian)力拖動系統。

      電(dian)力(li)推動(dong)系(xi)統是為電(dian)梯(ti)運行(xing)提供動(dong)力(li)、進行(xing)電(dian)梯(ti)控制的系(xi)統，由以下兒部分組成:1曳引(yin)電(dian)動(dong)機 是電(dian)梯(ti)的動(dong)力(li)源，有交流電(dian)動(dong)機和直流電(dian)動(dong)機兩(liang)種。

      供電(dian)(dian)(dian)(dian)系統是為電(dian)(dian)(dian)(dian)梯(ti)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)機提供電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)(de)裝(zhuang)(zhuang)置。 電(dian)(dian)(dian)(dian)梯(ti)一般應有(you)專用回路供電(dian)(dian)(dian)(dian)，每臺電(dian)(dian)(dian)(dian)梯(ti)應裝(zhuang)(zhuang)設單(dan)獨的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)開(kai)關(guan)和保護裝(zhuang)(zhuang)置，開(kai)關(guan)應安裝(zhuang)(zhuang)在機房內便于操作和維修的(de)(de)(de)(de)地方。各種電(dian)(dian)(dian)(dian)梯(ti)的(de)(de)(de)(de)供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓都(dou)是380V三相(xiang)交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)梯(ti)是由(you)交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)向直(zhi)流(liu)(liu)(liu)發(fa)電(dian)(dian)(dian)(dian)機組(zu)供電(dian)(dian)(dian)(dian)，再由(you)直(zhi)流(liu)(liu)(liu)發(fa)電(dian)(dian)(dian)(dian)機組(zu)向直(zhi)流(liu)(liu)(liu)牽(qian)引電(dian)(dian)(dian)(dian)動機供電(dian)(dian)(dian)(dian);或由(you)交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)經可(ke)控(kong)硅整流(liu)(liu)(liu)成直(zhi)流(liu)(liu)(liu)，再向直(zhi)流(liu)(liu)(liu)牽(qian)引電(dian)(dian)(dian)(dian)動機供電(dian)(dian)(dian)(dian)。除了作為動力的(de)(de)(de)(de)三相(xiang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)以外，還應有(you)單(dan)相(xiang)照明用電(dian)(dian)(dian)(dian)，故要求電(dian)(dian)(dian)(dian)梯(ti)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)線(xian)中應有(you)工(gong)作零線(xian)，即采(cai)用三線(xian)四線(xian)制(zhi)供電(dian)(dian)(dian)(dian)或三相(xiang)五(wu)線(xian)制(zhi)供電(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，建筑網片廠家介紹電力拖(tuo)動系(xi)統。

      電(dian)梯(ti)的電(dian)氣(qi)控(kong)(kong)制系(xi)(xi)統(tong)的種(zhong)類很多，可以按(an)其控(kong)(kong)制電(dian)氣(qi)控(kong)(kong)制系(xi)(xi)統(tong)是電(dian)梯(ti)各系(xi)(xi)統(tong)中較(jiao)重要系(xi)(xi)統(tong)之(zhi)一，方式(shi)分為手柄操作控(kong)(kong)制系(xi)(xi)統(tong)、 按(an)鈕控(kong)(kong)制系(xi)(xi)它決定著電(dian)梯(ti)的性能和自動(dong)化程度，建(jian)筑網片(pian)廠家(jia)介紹(shao)電(dian)力拖動(dong)系(xi)(xi)統(tong)。
