建筑網(wang)片廠家介(jie)紹(shao)電力拖動(dong)系統。

      電(dian)力推動(dong)系(xi)統(tong)是(shi)為電(dian)梯(ti)運行提(ti)供動(dong)力、進行電(dian)梯(ti)控制的(de)系(xi)統(tong)，由(you)以(yi)下兒部分組成(cheng):1曳引電(dian)動(dong)機 是(shi)電(dian)梯(ti)的(de)動(dong)力源，有交流電(dian)動(dong)機和直流電(dian)動(dong)機兩種。

      供(gong)(gong)電(dian)(dian)(dian)系統是(shi)為電(dian)(dian)(dian)梯(ti)(ti)的(de)電(dian)(dian)(dian)機提(ti)供(gong)(gong)電(dian)(dian)(dian)源(yuan)的(de)裝置(zhi)。 電(dian)(dian)(dian)梯(ti)(ti)一般應有(you)專用回路供(gong)(gong)電(dian)(dian)(dian)，每臺電(dian)(dian)(dian)梯(ti)(ti)應裝設單獨(du)的(de)電(dian)(dian)(dian)源(yuan)開(kai)關和保護(hu)裝置(zhi)，開(kai)關應安裝在(zai)機房內(nei)便于操作(zuo)和維修的(de)地方。各(ge)種電(dian)(dian)(dian)梯(ti)(ti)的(de)供(gong)(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓都是(shi)380V三(san)相交(jiao)流(liu)電(dian)(dian)(dian)，直流(liu)電(dian)(dian)(dian)梯(ti)(ti)是(shi)由(you)交(jiao)流(liu)電(dian)(dian)(dian)源(yuan)向(xiang)直流(liu)發(fa)(fa)電(dian)(dian)(dian)機組(zu)供(gong)(gong)電(dian)(dian)(dian)，再(zai)(zai)由(you)直流(liu)發(fa)(fa)電(dian)(dian)(dian)機組(zu)向(xiang)直流(liu)牽引電(dian)(dian)(dian)動(dong)機供(gong)(gong)電(dian)(dian)(dian);或(huo)由(you)交(jiao)流(liu)電(dian)(dian)(dian)源(yuan)經可(ke)控(kong)硅整流(liu)成(cheng)直流(liu)，再(zai)(zai)向(xiang)直流(liu)牽引電(dian)(dian)(dian)動(dong)機供(gong)(gong)電(dian)(dian)(dian)。除了作(zuo)為動(dong)力的(de)三(san)相電(dian)(dian)(dian)源(yuan)以外，還應有(you)單相照明用電(dian)(dian)(dian)，故(gu)要求(qiu)電(dian)(dian)(dian)梯(ti)(ti)的(de)電(dian)(dian)(dian)源(yuan)線中應有(you)工(gong)作(zuo)零線，即采用三(san)線四(si)線制供(gong)(gong)電(dian)(dian)(dian)或(huo)三(san)相五線制供(gong)(gong)電(dian)(dian)(dian)。民，消(xiao)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動(dong)系(xi)統(tong)。

      電(dian)梯的電(dian)氣(qi)控(kong)制系統(tong)的種(zhong)類很多(duo)，可以按(an)其控(kong)制電(dian)氣(qi)控(kong)制系統(tong)是電(dian)梯各系統(tong)中較重要系統(tong)之一，方式(shi)分(fen)為(wei)手柄操作(zuo)控(kong)制系統(tong)、 按(an)鈕控(kong)制系它(ta)決定著電(dian)梯的性能和自(zi)動化程度，建筑網片廠家介紹電(dian)力拖動系統(tong)。
