建筑網(wang)片(pian)廠家(jia)介紹電力拖動系統。

      電(dian)(dian)力推動(dong)(dong)系統是(shi)為電(dian)(dian)梯(ti)運行(xing)提供動(dong)(dong)力、進(jin)行(xing)電(dian)(dian)梯(ti)控(kong)制的系統，由以下兒部分組(zu)成:1曳(ye)引電(dian)(dian)動(dong)(dong)機(ji) 是(shi)電(dian)(dian)梯(ti)的動(dong)(dong)力源，有(you)交流電(dian)(dian)動(dong)(dong)機(ji)和直流電(dian)(dian)動(dong)(dong)機(ji)兩種。

      供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系統是(shi)為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)梯的電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)提供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的裝置。 電(dian)(dian)(dian)(dian)(dian)(dian)梯一般應有專(zhuan)用回路供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，每臺電(dian)(dian)(dian)(dian)(dian)(dian)梯應裝設單獨的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)開關和保護裝置，開關應安(an)裝在(zai)機(ji)房內便于操作和維修的地方。各種電(dian)(dian)(dian)(dian)(dian)(dian)梯的供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓都是(shi)380V三(san)(san)相(xiang)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)梯是(shi)由(you)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)向直(zhi)流(liu)發電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)組供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，再(zai)(zai)由(you)直(zhi)流(liu)發電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)組向直(zhi)流(liu)牽(qian)引電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian);或由(you)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)經可控硅整流(liu)成直(zhi)流(liu)，再(zai)(zai)向直(zhi)流(liu)牽(qian)引電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。除了作為(wei)動(dong)力的三(san)(san)相(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)以外，還(huan)應有單相(xiang)照明用電(dian)(dian)(dian)(dian)(dian)(dian)，故要求電(dian)(dian)(dian)(dian)(dian)(dian)梯的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian)中應有工作零(ling)線(xian)，即(ji)采用三(san)(san)線(xian)四線(xian)制供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)或三(san)(san)相(xiang)五(wu)線(xian)制供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。民，消(xiao)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，建筑網片廠家介紹(shao)電力拖動系(xi)統。

      電(dian)(dian)梯的(de)(de)電(dian)(dian)氣控制系(xi)統(tong)的(de)(de)種(zhong)類很多，可以按其控制電(dian)(dian)氣控制系(xi)統(tong)是電(dian)(dian)梯各系(xi)統(tong)中(zhong)較(jiao)重要系(xi)統(tong)之一，方式分(fen)為(wei)手柄(bing)操(cao)作控制系(xi)統(tong)、 按鈕(niu)控制系(xi)它決定著(zhu)電(dian)(dian)梯的(de)(de)性能和自動化程度，建筑網片(pian)廠家(jia)介紹(shao)電(dian)(dian)力拖(tuo)動系(xi)統(tong)。
