箱式變壓器廠家的箱(xiang)式(shi)(shi)變(bian)(bian)(bian)壓(ya)器分歐式(shi)(shi)（European style）和(he)美式(shi)(shi)（American style），美式(shi)(shi)體(ti)積（Volume0)小(xiao)(xiao)，負(fu)荷(he)能(neng)力較低，供(gong)電可(ke)靠性(xing)不(bu)高，歐式(shi)(shi)體(ti)積較大，負(fu)荷(he)能(neng)力與供(gong)電可(ke)靠性(xing)都比美式(shi)(shi)強(qiang)，在我國一般用(yong)的都是歐式(shi)(shi)箱(xiang)變(bian)(bian)(bian)。箱(xiang)式(shi)(shi)變(bian)(bian)(bian)壓(ya)器并不(bu)只(zhi)是變(bian)(bian)(bian)壓(ya)器，它(ta)相當于一個小(xiao)(xiao)型(xing)變(bian)(bian)(bian)電站(zhan)，屬于配電站(zhan)，直接向用(yong)戶提供(gong)電源。

包括高(gao)壓(ya)(ya)(ya)(ya)(ya)室(shi)，變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)室(shi)，低壓(ya)(ya)(ya)(ya)(ya)室(shi)；高(gao)壓(ya)(ya)(ya)(ya)(ya)室(shi)就是電(dian)源(yuan)側，一(yi)般是35千(qian)伏或(huo)(huo)者(zhe)10千(qian)伏進(jin)線(xian)，包括高(gao)壓(ya)(ya)(ya)(ya)(ya)母(mu)排(pai)(pai)（High voltage busbar）、斷(duan)路(lu)器(qi)(qi)(qi)(qi)或(huo)(huo)者(zhe)熔(rong)斷(duan)器(qi)(qi)(qi)(qi)、電(dian)壓(ya)(ya)(ya)(ya)(ya)互感器(qi)(qi)(qi)(qi)、避雷(lei)器(qi)(qi)(qi)(qi)等(deng)，變壓(ya)(ya)(ya)(ya)(ya)室(shi)里(li)都是變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)是箱變的主要(yao)設備，低壓(ya)(ya)(ya)(ya)(ya)室(shi)里(li)面有低壓(ya)(ya)(ya)(ya)(ya)母(mu)排(pai)(pai)(Low voltage busbar)、低壓(ya)(ya)(ya)(ya)(ya)斷(duan)路(lu)器(qi)(qi)(qi)(qi)、計量裝置(zhi)、避雷(lei)器(qi)(qi)(qi)(qi)等(deng)，從低壓(ya)(ya)(ya)(ya)(ya)母(mu)排(pai)(pai)上引出線(xian)路(lu)對用戶供電(dian)。
