建筑(zhu)網片廠家介紹(shao)電(dian)力(li)拖動系統。

      電力推動(dong)(dong)系統是為電梯運行提供動(dong)(dong)力、進行電梯控(kong)制的系統，由以下兒部分組成:1曳(ye)引電動(dong)(dong)機(ji) 是電梯的動(dong)(dong)力源，有交流電動(dong)(dong)機(ji)和直流電動(dong)(dong)機(ji)兩種。

      供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系統是為電(dian)(dian)(dian)(dian)(dian)梯(ti)的(de)(de)電(dian)(dian)(dian)(dian)(dian)機(ji)提供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)裝(zhuang)(zhuang)置。 電(dian)(dian)(dian)(dian)(dian)梯(ti)一般應(ying)有專(zhuan)用回(hui)路供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)，每臺電(dian)(dian)(dian)(dian)(dian)梯(ti)應(ying)裝(zhuang)(zhuang)設(she)單(dan)獨的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)開(kai)關和保護裝(zhuang)(zhuang)置，開(kai)關應(ying)安裝(zhuang)(zhuang)在(zai)機(ji)房(fang)內便于(yu)操作和維修的(de)(de)地方。各種電(dian)(dian)(dian)(dian)(dian)梯(ti)的(de)(de)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓都是380V三相(xiang)(xiang)交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)梯(ti)是由交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)向直(zhi)(zhi)流(liu)(liu)(liu)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)組供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)，再由直(zhi)(zhi)流(liu)(liu)(liu)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)組向直(zhi)(zhi)流(liu)(liu)(liu)牽(qian)(qian)引電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian);或(huo)由交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)經可控硅整流(liu)(liu)(liu)成(cheng)直(zhi)(zhi)流(liu)(liu)(liu)，再向直(zhi)(zhi)流(liu)(liu)(liu)牽(qian)(qian)引電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。除了作為動(dong)力的(de)(de)三相(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)源(yuan)以外，還應(ying)有單(dan)相(xiang)(xiang)照明(ming)用電(dian)(dian)(dian)(dian)(dian)，故(gu)要求電(dian)(dian)(dian)(dian)(dian)梯(ti)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)線中應(ying)有工作零(ling)線，即采用三線四線制供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)或(huo)三相(xiang)(xiang)五線制供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。民，消技水(shui)出
