箱式變壓器廠家的(de)箱(xiang)式(shi)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)分歐式(shi)（European style）和美(mei)式(shi)（American style），美(mei)式(shi)體積（Volume0)小(xiao)，負荷能力(li)較(jiao)低(di)(di)(di)，供(gong)電可(ke)靠性不高，歐式(shi)體積較(jiao)大，負荷能力(li)與供(gong)電可(ke)靠性都(dou)(dou)比(bi)美(mei)式(shi)強，在我國(guo)一(yi)(yi)般用的(de)都(dou)(dou)是(shi)歐式(shi)箱(xiang)變(bian)(bian)(bian)。箱(xiang)式(shi)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)并(bing)不只是(shi)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)，它相當于(yu)一(yi)(yi)個(ge)小(xiao)型變(bian)(bian)(bian)電站，屬于(yu)配電站，直接向用戶提供(gong)電源。包(bao)括高壓(ya)(ya)(ya)室(shi)(shi)，變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)室(shi)(shi)，低(di)(di)(di)壓(ya)(ya)(ya)室(shi)(shi)；高壓(ya)(ya)(ya)室(shi)(shi)就是(shi)電源側，一(yi)(yi)般是(shi)35千伏或者10千伏進線(xian)，包(bao)括高壓(ya)(ya)(ya)母排（High voltage busbar）、斷(duan)路器(qi)(qi)(qi)或者熔斷(duan)器(qi)(qi)(qi)、電壓(ya)(ya)(ya)互感器(qi)(qi)(qi)、避雷(lei)器(qi)(qi)(qi)等(deng)，變(bian)(bian)(bian)壓(ya)(ya)(ya)室(shi)(shi)里都(dou)(dou)是(shi)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)是(shi)箱(xiang)變(bian)(bian)(bian)的(de)主要設備(bei)，低(di)(di)(di)壓(ya)(ya)(ya)室(shi)(shi)里面(mian)有(you)低(di)(di)(di)壓(ya)(ya)(ya)母排(Low voltage busbar)、低(di)(di)(di)壓(ya)(ya)(ya)斷(duan)路器(qi)(qi)(qi)、計量裝置、避雷(lei)器(qi)(qi)(qi)等(deng)，從(cong)低(di)(di)(di)壓(ya)(ya)(ya)母排上引出(chu)線(xian)路對(dui)用戶供(gong)電。

組(zu)(zu)合式變壓器（俗稱美式箱(xiang)變也叫箱(xiang)式變壓器）是將變壓器、高壓受電(dian)部分的(de)負荷開(kai)關及保護裝置、低(di)壓配電(dian)裝置、低(di)壓計量系統和無功補償(chang)裝置組(zu)(zu)合在一起的(de)成套變配電(dian)設備(bei)。

組合(he)式(shi)變壓器（俗(su)稱美式(shi)箱(xiang)變）

組合(he)式變壓(ya)器（俗稱(cheng)美(mei)式箱變）主要特點：

全(quan)(quan)密(mi)封、全(quan)(quan)絕緣(yuan)、結(jie)構(gou)緊湊、外形美觀、體(ti)積僅為箱(xiang)式(shi)變電(dian)站(zhan)（歐式(shi)箱(xiang)變）的1/3左右。無須配電(dian)房，可直接安(an)放在室(shi)內(nei)或室(shi)外，也(ye)可安(an)放在街道兩旁和綠化帶內(nei)，可靠地保(bao)證(zheng)了人身安(an)全(quan)(quan)，既是供電(dian)設施(shi)，又(you)可裝點(dian)環境。

組合式(shi)變(bian)(bian)壓(ya)器（俗稱美式(shi)箱變(bian)(bian)也(ye)叫箱式(shi)變(bian)(bian)壓(ya)器）可用于終端(duan)供電(dian)和(he)環網供電(dian)，轉(zhuan)換(huan)十分方便(bian)，保證了供電(dian)的可靠性、靈活性。

采用雙熔絲全范圍保護(hu)方式，大(da)大(da)降低(di)了運(yun)行成本。

10kV套管(guan)電纜頭可在(zai)200A負荷電流下多次插拔，在(zai)緊急(ji)情(qing)況下作負荷開(kai)關使用，并具有隔離(li)開(kai)關的特點。

組合式(shi)變(bian)壓器（俗稱美式(shi)箱變(bian)也叫箱式(shi)變(bian)壓器）采用(yong)國(guo)內9型、11型配電變(bian)壓器，損(sun)耗低，噪音低，使用(yong)壽(shou)命長。
