建筑網片廠家介紹(shao)電力拖動系統。

      電(dian)力推動系統(tong)是為電(dian)梯(ti)(ti)運行(xing)提(ti)供動力、進行(xing)電(dian)梯(ti)(ti)控制的系統(tong)，由以下兒(er)部分組成:1曳(ye)引電(dian)動機 是電(dian)梯(ti)(ti)的動力源(yuan)，有(you)交流(liu)電(dian)動機和直流(liu)電(dian)動機兩種。

      供(gong)(gong)電(dian)(dian)(dian)(dian)系統是(shi)為電(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)(de)電(dian)(dian)(dian)(dian)機(ji)(ji)提供(gong)(gong)電(dian)(dian)(dian)(dian)源的(de)(de)裝(zhuang)置(zhi)。 電(dian)(dian)(dian)(dian)梯(ti)(ti)一般應(ying)(ying)(ying)(ying)有專用(yong)回路供(gong)(gong)電(dian)(dian)(dian)(dian)，每(mei)臺電(dian)(dian)(dian)(dian)梯(ti)(ti)應(ying)(ying)(ying)(ying)裝(zhuang)設單(dan)獨的(de)(de)電(dian)(dian)(dian)(dian)源開(kai)關和保護裝(zhuang)置(zhi)，開(kai)關應(ying)(ying)(ying)(ying)安裝(zhuang)在機(ji)(ji)房內便于操(cao)作和維(wei)修的(de)(de)地方。各種電(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)(de)供(gong)(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓都是(shi)380V三(san)(san)相交流電(dian)(dian)(dian)(dian)，直(zhi)流電(dian)(dian)(dian)(dian)梯(ti)(ti)是(shi)由交流電(dian)(dian)(dian)(dian)源向(xiang)直(zhi)流發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)組供(gong)(gong)電(dian)(dian)(dian)(dian)，再由直(zhi)流發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)組向(xiang)直(zhi)流牽引(yin)電(dian)(dian)(dian)(dian)動機(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian);或(huo)由交流電(dian)(dian)(dian)(dian)源經可控硅整流成直(zhi)流，再向(xiang)直(zhi)流牽引(yin)電(dian)(dian)(dian)(dian)動機(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)。除了(le)作為動力的(de)(de)三(san)(san)相電(dian)(dian)(dian)(dian)源以(yi)外，還(huan)應(ying)(ying)(ying)(ying)有單(dan)相照明用(yong)電(dian)(dian)(dian)(dian)，故要求電(dian)(dian)(dian)(dian)梯(ti)(ti)的(de)(de)電(dian)(dian)(dian)(dian)源線(xian)(xian)中(zhong)應(ying)(ying)(ying)(ying)有工作零線(xian)(xian)，即采用(yong)三(san)(san)線(xian)(xian)四(si)線(xian)(xian)制供(gong)(gong)電(dian)(dian)(dian)(dian)或(huo)三(san)(san)相五線(xian)(xian)制供(gong)(gong)電(dian)(dian)(dian)(dian)。民，消技水出
