建筑(zhu)網片廠家介紹電力拖動系統。

      電(dian)(dian)(dian)(dian)力(li)推動(dong)(dong)(dong)系統是為電(dian)(dian)(dian)(dian)梯運行提供動(dong)(dong)(dong)力(li)、進行電(dian)(dian)(dian)(dian)梯控制(zhi)的(de)系統，由以下兒部分組(zu)成:1曳引電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji) 是電(dian)(dian)(dian)(dian)梯的(de)動(dong)(dong)(dong)力(li)源，有交(jiao)流(liu)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)和直流(liu)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)兩種(zhong)。

      供電(dian)(dian)(dian)系統(tong)是(shi)(shi)為電(dian)(dian)(dian)梯(ti)(ti)的(de)電(dian)(dian)(dian)機(ji)(ji)提供電(dian)(dian)(dian)源的(de)裝(zhuang)置(zhi)。 電(dian)(dian)(dian)梯(ti)(ti)一(yi)般應(ying)有(you)專(zhuan)用(yong)回路(lu)供電(dian)(dian)(dian)，每臺電(dian)(dian)(dian)梯(ti)(ti)應(ying)裝(zhuang)設單獨(du)的(de)電(dian)(dian)(dian)源開(kai)關和保護裝(zhuang)置(zhi)，開(kai)關應(ying)安裝(zhuang)在機(ji)(ji)房內便于操作和維修的(de)地(di)方。各種電(dian)(dian)(dian)梯(ti)(ti)的(de)供電(dian)(dian)(dian)電(dian)(dian)(dian)壓都是(shi)(shi)380V三(san)相交(jiao)流(liu)(liu)電(dian)(dian)(dian)，直(zhi)(zhi)(zhi)流(liu)(liu)電(dian)(dian)(dian)梯(ti)(ti)是(shi)(shi)由(you)交(jiao)流(liu)(liu)電(dian)(dian)(dian)源向(xiang)(xiang)直(zhi)(zhi)(zhi)流(liu)(liu)發電(dian)(dian)(dian)機(ji)(ji)組供電(dian)(dian)(dian)，再(zai)(zai)由(you)直(zhi)(zhi)(zhi)流(liu)(liu)發電(dian)(dian)(dian)機(ji)(ji)組向(xiang)(xiang)直(zhi)(zhi)(zhi)流(liu)(liu)牽(qian)引電(dian)(dian)(dian)動機(ji)(ji)供電(dian)(dian)(dian);或由(you)交(jiao)流(liu)(liu)電(dian)(dian)(dian)源經(jing)可控(kong)硅整流(liu)(liu)成直(zhi)(zhi)(zhi)流(liu)(liu)，再(zai)(zai)向(xiang)(xiang)直(zhi)(zhi)(zhi)流(liu)(liu)牽(qian)引電(dian)(dian)(dian)動機(ji)(ji)供電(dian)(dian)(dian)。除了作為動力(li)的(de)三(san)相電(dian)(dian)(dian)源以(yi)外，還應(ying)有(you)單相照明用(yong)電(dian)(dian)(dian)，故要(yao)求電(dian)(dian)(dian)梯(ti)(ti)的(de)電(dian)(dian)(dian)源線中應(ying)有(you)工作零(ling)線，即采用(yong)三(san)線四線制供電(dian)(dian)(dian)或三(san)相五線制供電(dian)(dian)(dian)。民，消技水出
