建筑(zhu)網(wang)片廠家介紹電力拖動系統。

      電(dian)力(li)(li)推動(dong)系統是為電(dian)梯運行提(ti)供動(dong)力(li)(li)、進行電(dian)梯控(kong)制(zhi)的系統，由以下兒部分組成(cheng):1曳(ye)引(yin)電(dian)動(dong)機 是電(dian)梯的動(dong)力(li)(li)源(yuan)，有交流電(dian)動(dong)機和直流電(dian)動(dong)機兩種。

      供(gong)電(dian)(dian)(dian)(dian)系統是為(wei)電(dian)(dian)(dian)(dian)梯(ti)的電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)提供(gong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的裝(zhuang)置。 電(dian)(dian)(dian)(dian)梯(ti)一(yi)般應有(you)專用(yong)回路供(gong)電(dian)(dian)(dian)(dian)，每臺電(dian)(dian)(dian)(dian)梯(ti)應裝(zhuang)設單獨的電(dian)(dian)(dian)(dian)源(yuan)(yuan)開關(guan)和保護裝(zhuang)置，開關(guan)應安裝(zhuang)在(zai)機(ji)(ji)(ji)房內便于操(cao)作和維修的地方。各種(zhong)電(dian)(dian)(dian)(dian)梯(ti)的供(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓都是380V三相(xiang)交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)梯(ti)是由交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)向(xiang)直流(liu)(liu)(liu)(liu)發電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)組供(gong)電(dian)(dian)(dian)(dian)，再由直流(liu)(liu)(liu)(liu)發電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)組向(xiang)直流(liu)(liu)(liu)(liu)牽引(yin)電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)供(gong)電(dian)(dian)(dian)(dian);或(huo)由交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)經可控硅整流(liu)(liu)(liu)(liu)成(cheng)直流(liu)(liu)(liu)(liu)，再向(xiang)直流(liu)(liu)(liu)(liu)牽引(yin)電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)供(gong)電(dian)(dian)(dian)(dian)。除了作為(wei)動(dong)力的三相(xiang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)以外，還應有(you)單相(xiang)照明(ming)用(yong)電(dian)(dian)(dian)(dian)，故要求電(dian)(dian)(dian)(dian)梯(ti)的電(dian)(dian)(dian)(dian)源(yuan)(yuan)線(xian)中(zhong)應有(you)工作零線(xian)，即采用(yong)三線(xian)四線(xian)制供(gong)電(dian)(dian)(dian)(dian)或(huo)三相(xiang)五線(xian)制供(gong)電(dian)(dian)(dian)(dian)。民，消技水(shui)出
