建筑網片廠家介(jie)紹電力拖動系統。

      電力(li)推(tui)動(dong)(dong)系(xi)統是為電梯(ti)運行提供(gong)動(dong)(dong)力(li)、進(jin)行電梯(ti)控(kong)制的系(xi)統，由(you)以下兒部分組(zu)成:1曳引電動(dong)(dong)機 是電梯(ti)的動(dong)(dong)力(li)源(yuan)，有交流電動(dong)(dong)機和(he)直流電動(dong)(dong)機兩種。

      供(gong)(gong)(gong)電(dian)(dian)(dian)系統是為電(dian)(dian)(dian)梯的(de)電(dian)(dian)(dian)機提(ti)供(gong)(gong)(gong)電(dian)(dian)(dian)源(yuan)(yuan)的(de)裝置(zhi)。 電(dian)(dian)(dian)梯一般(ban)應(ying)(ying)有專(zhuan)用回(hui)路供(gong)(gong)(gong)電(dian)(dian)(dian)，每臺電(dian)(dian)(dian)梯應(ying)(ying)裝設單獨的(de)電(dian)(dian)(dian)源(yuan)(yuan)開關(guan)(guan)和(he)(he)保護裝置(zhi)，開關(guan)(guan)應(ying)(ying)安裝在(zai)機房(fang)內便于操作和(he)(he)維(wei)修的(de)地方(fang)。各種(zhong)電(dian)(dian)(dian)梯的(de)供(gong)(gong)(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓都(dou)是380V三相(xiang)交流(liu)(liu)(liu)電(dian)(dian)(dian)，直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)梯是由(you)交流(liu)(liu)(liu)電(dian)(dian)(dian)源(yuan)(yuan)向直(zhi)(zhi)流(liu)(liu)(liu)發(fa)電(dian)(dian)(dian)機組供(gong)(gong)(gong)電(dian)(dian)(dian)，再由(you)直(zhi)(zhi)流(liu)(liu)(liu)發(fa)電(dian)(dian)(dian)機組向直(zhi)(zhi)流(liu)(liu)(liu)牽引電(dian)(dian)(dian)動(dong)(dong)機供(gong)(gong)(gong)電(dian)(dian)(dian);或由(you)交流(liu)(liu)(liu)電(dian)(dian)(dian)源(yuan)(yuan)經可控硅整流(liu)(liu)(liu)成直(zhi)(zhi)流(liu)(liu)(liu)，再向直(zhi)(zhi)流(liu)(liu)(liu)牽引電(dian)(dian)(dian)動(dong)(dong)機供(gong)(gong)(gong)電(dian)(dian)(dian)。除(chu)了作為動(dong)(dong)力的(de)三相(xiang)電(dian)(dian)(dian)源(yuan)(yuan)以外(wai)，還(huan)應(ying)(ying)有單相(xiang)照明用電(dian)(dian)(dian)，故要求(qiu)電(dian)(dian)(dian)梯的(de)電(dian)(dian)(dian)源(yuan)(yuan)線(xian)中應(ying)(ying)有工作零線(xian)，即采用三線(xian)四線(xian)制供(gong)(gong)(gong)電(dian)(dian)(dian)或三相(xiang)五線(xian)制供(gong)(gong)(gong)電(dian)(dian)(dian)。民，消(xiao)技水出(chu)
