建筑網片(pian)廠家(jia)介紹電力拖動系統。

      電力推動(dong)系(xi)統是(shi)為電梯(ti)運行(xing)提供動(dong)力、進行(xing)電梯(ti)控制(zhi)的(de)系(xi)統，由以下(xia)兒部分組成:1曳(ye)引(yin)電動(dong)機 是(shi)電梯(ti)的(de)動(dong)力源，有交(jiao)流電動(dong)機和直流電動(dong)機兩(liang)種(zhong)。

      供電(dian)(dian)(dian)(dian)(dian)系統是為(wei)電(dian)(dian)(dian)(dian)(dian)梯(ti)的電(dian)(dian)(dian)(dian)(dian)機提供電(dian)(dian)(dian)(dian)(dian)源的裝(zhuang)置。 電(dian)(dian)(dian)(dian)(dian)梯(ti)一般應有專用(yong)回路供電(dian)(dian)(dian)(dian)(dian)，每臺電(dian)(dian)(dian)(dian)(dian)梯(ti)應裝(zhuang)設單獨(du)的電(dian)(dian)(dian)(dian)(dian)源開關(guan)和保護裝(zhuang)置，開關(guan)應安裝(zhuang)在機房內便于操作和維修的地方。各種電(dian)(dian)(dian)(dian)(dian)梯(ti)的供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓都是380V三(san)相(xiang)交流(liu)電(dian)(dian)(dian)(dian)(dian)，直流(liu)電(dian)(dian)(dian)(dian)(dian)梯(ti)是由(you)交流(liu)電(dian)(dian)(dian)(dian)(dian)源向直流(liu)發電(dian)(dian)(dian)(dian)(dian)機組供電(dian)(dian)(dian)(dian)(dian)，再(zai)由(you)直流(liu)發電(dian)(dian)(dian)(dian)(dian)機組向直流(liu)牽引(yin)電(dian)(dian)(dian)(dian)(dian)動(dong)機供電(dian)(dian)(dian)(dian)(dian);或由(you)交流(liu)電(dian)(dian)(dian)(dian)(dian)源經可控硅(gui)整(zheng)流(liu)成直流(liu)，再(zai)向直流(liu)牽引(yin)電(dian)(dian)(dian)(dian)(dian)動(dong)機供電(dian)(dian)(dian)(dian)(dian)。除了(le)作為(wei)動(dong)力的三(san)相(xiang)電(dian)(dian)(dian)(dian)(dian)源以外，還應有單相(xiang)照明用(yong)電(dian)(dian)(dian)(dian)(dian)，故要求電(dian)(dian)(dian)(dian)(dian)梯(ti)的電(dian)(dian)(dian)(dian)(dian)源線(xian)中應有工作零線(xian)，即采用(yong)三(san)線(xian)四線(xian)制(zhi)供電(dian)(dian)(dian)(dian)(dian)或三(san)相(xiang)五線(xian)制(zhi)供電(dian)(dian)(dian)(dian)(dian)。民，消技水出(chu)

      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)家介紹電力拖動系(xi)統。

      電(dian)(dian)(dian)梯(ti)的(de)電(dian)(dian)(dian)氣(qi)控(kong)制(zhi)系(xi)統的(de)種類很多，可以按(an)其(qi)控(kong)制(zhi)電(dian)(dian)(dian)氣(qi)控(kong)制(zhi)系(xi)統是電(dian)(dian)(dian)梯(ti)各系(xi)統中(zhong)較重要系(xi)統之一，方式分為手(shou)柄操作控(kong)制(zhi)系(xi)統、 按(an)鈕控(kong)制(zhi)系(xi)它決定(ding)著電(dian)(dian)(dian)梯(ti)的(de)性能和自動化(hua)程(cheng)度，建筑(zhu)網片廠家介紹電(dian)(dian)(dian)力(li)拖動系(xi)統。
