建筑(zhu)網片廠(chang)家(jia)介紹(shao)電力拖動系統。

      電(dian)(dian)(dian)力推動(dong)系(xi)統(tong)是為電(dian)(dian)(dian)梯(ti)運行(xing)提供動(dong)力、進行(xing)電(dian)(dian)(dian)梯(ti)控制的(de)系(xi)統(tong)，由以(yi)下(xia)兒部分組成:1曳引電(dian)(dian)(dian)動(dong)機 是電(dian)(dian)(dian)梯(ti)的(de)動(dong)力源，有交流電(dian)(dian)(dian)動(dong)機和直流電(dian)(dian)(dian)動(dong)機兩種。

      供(gong)電(dian)(dian)系統是為電(dian)(dian)梯(ti)(ti)的(de)(de)(de)電(dian)(dian)機(ji)(ji)提供(gong)電(dian)(dian)源的(de)(de)(de)裝(zhuang)置。 電(dian)(dian)梯(ti)(ti)一(yi)般應有(you)專(zhuan)用回(hui)路供(gong)電(dian)(dian)，每臺電(dian)(dian)梯(ti)(ti)應裝(zhuang)設單(dan)(dan)獨的(de)(de)(de)電(dian)(dian)源開關和保護(hu)裝(zhuang)置，開關應安裝(zhuang)在機(ji)(ji)房內便于(yu)操作和維修的(de)(de)(de)地(di)方。各種電(dian)(dian)梯(ti)(ti)的(de)(de)(de)供(gong)電(dian)(dian)電(dian)(dian)壓(ya)都是380V三(san)(san)相交(jiao)流(liu)(liu)電(dian)(dian)，直(zhi)(zhi)流(liu)(liu)電(dian)(dian)梯(ti)(ti)是由交(jiao)流(liu)(liu)電(dian)(dian)源向(xiang)(xiang)直(zhi)(zhi)流(liu)(liu)發電(dian)(dian)機(ji)(ji)組供(gong)電(dian)(dian)，再由直(zhi)(zhi)流(liu)(liu)發電(dian)(dian)機(ji)(ji)組向(xiang)(xiang)直(zhi)(zhi)流(liu)(liu)牽引電(dian)(dian)動機(ji)(ji)供(gong)電(dian)(dian);或由交(jiao)流(liu)(liu)電(dian)(dian)源經可控硅整流(liu)(liu)成直(zhi)(zhi)流(liu)(liu)，再向(xiang)(xiang)直(zhi)(zhi)流(liu)(liu)牽引電(dian)(dian)動機(ji)(ji)供(gong)電(dian)(dian)。除了作為動力的(de)(de)(de)三(san)(san)相電(dian)(dian)源以(yi)外，還(huan)應有(you)單(dan)(dan)相照(zhao)明用電(dian)(dian)，故要求電(dian)(dian)梯(ti)(ti)的(de)(de)(de)電(dian)(dian)源線(xian)中應有(you)工作零線(xian)，即采用三(san)(san)線(xian)四線(xian)制(zhi)供(gong)電(dian)(dian)或三(san)(san)相五(wu)線(xian)制(zhi)供(gong)電(dian)(dian)。民，消技水出

      電氣控制系統速度反饋裝置和電動機調速裝置 起對曳引電動機進行調速的作用，建筑網片廠家(jia)介紹電力拖動系(xi)統。

      電(dian)(dian)(dian)梯的(de)電(dian)(dian)(dian)氣控(kong)制(zhi)系(xi)統(tong)的(de)種類(lei)很多，可(ke)以按(an)其控(kong)制(zhi)電(dian)(dian)(dian)氣控(kong)制(zhi)系(xi)統(tong)是電(dian)(dian)(dian)梯各系(xi)統(tong)中較重要系(xi)統(tong)之一，方式分為手(shou)柄操作(zuo)控(kong)制(zhi)系(xi)統(tong)、 按(an)鈕控(kong)制(zhi)系(xi)它(ta)決定著電(dian)(dian)(dian)梯的(de)性(xing)能和自(zi)動化程度，建筑(zhu)網片廠(chang)家介(jie)紹電(dian)(dian)(dian)力拖動系(xi)統(tong)。
