一般來說，我們可以根據外型迅速區別美式箱變和美式箱變。并且，因為美式箱變和美式箱變的結構特征和穩定性不一樣，運用場所也不一樣。實際區別如下所示:　　

1)歐美國家兩(liang)室布線(xian)(xian)方式(shi)的(de)區別:　　美國箱式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)一(yi)般(ban)有(you)一(yi)兩(liang)個10KV進線(xian)(xian)，低(di)電(dian)壓(ya)(ya)小組(zu)(zu)出(chu)線(xian)(xian)電(dian)纜(lan)線(xian)(xian)，4~6有(you)單獨(du)變(bian)(bian)(bian)電(dian)器(qi)，變(bian)(bian)(bian)壓(ya)(ya)器(qi)一(yi)般(ban)為(wei)(wei)500KVA~800KVA。當歐洲箱式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)為(wei)(wei)單獨(du)變(bian)(bian)(bian)壓(ya)(ya)器(qi)時，有(you)兩(liang)個10KV進線(xian)(xian)，單個變(bian)(bian)(bian)壓(ya)(ya)器(qi)一(yi)般(ban)為(wei)(wei)500KVA~800KVA，低(di)電(dian)壓(ya)(ya)小組(zu)(zu)出(chu)線(xian)(xian)電(dian)纜(lan)線(xian)(xian)一(yi)般(ban)為(wei)(wei)4~6路。2個變(bian)(bian)(bian)壓(ya)(ya)器(qi)有(you)兩(liang)個10KV進線(xian)(xian)，每一(yi)個變(bian)(bian)(bian)壓(ya)(ya)器(qi)為(wei)(wei)500KVA~800KKVA，低(di)電(dian)壓(ya)(ya)小組(zu)(zu)出(chu)線(xian)(xian)電(dian)纜(lan)線(xian)(xian)一(yi)般(ban)為(wei)(wei)8~12。

2)歐美國家兩室箱變內關鍵構件的區別：　　美式箱式變壓器一般由變電器、10KV環網電源開關、10KV電纜線電源插頭、低電壓樁帽箱等關鍵零部件構成。它具備體型小、低成本、安裝便捷等優勢。歐式古典箱式變壓器關鍵由變電器、10KV環網高壓開關柜、電力電容器、低壓開關等關鍵零部件構成，等同于將三型站的機器設備緊密安裝在金屬材料箱里，使三型站微型化。歐式古典箱式變壓器的容積超過美式箱式變壓器，成本費超過美式箱式變壓器。　　

3)歐(ou)美國家兩式箱(xiang)變的(de)優(you)點(dian)和缺點(dian)：　　

美國箱(xiang)式變壓(ya)器具備(bei)體(ti)型(xing)小、占(zhan)地總(zong)面積(ji)小、安裝(zhuang)便捷、掩(yan)藏便捷、與社區環(huan)境融(rong)洽等優勢。它可以減(jian)少電(dian)(dian)(dian)(dian)(dian)(dian)纜線(xian)的長度，降低(di)配電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)路耗(hao)損，減(jian)少配電(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)成(cheng)本(ben)費。美式箱(xiang)式變壓(ya)器的不(bu)足(zu)之處是(shi)配電(dian)(dian)(dian)(dian)(dian)(dian)穩定性低(di);沒有電(dian)(dian)(dian)(dian)(dian)(dian)動式組(zu)織(zhi)，配電(dian)(dian)(dian)(dian)(dian)(dian)自動化設備(bei)沒法提(ti)(ti)升;沒有電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)容器設備(bei)，不(bu)利降低(di)配電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)路耗(hao)損;噪聲高過(guo)三級(ji)站(zhan)(zhan)(zhan)和(he)(he)五級(ji)站(zhan)(zhan)(zhan)，由于三級(ji)站(zhan)(zhan)(zhan)和(he)(he)五級(ji)站(zhan)(zhan)(zhan)將變電(dian)(dian)(dian)(dian)(dian)(dian)器置放在房間(jian)內(nei)，具有隔(ge)音降噪功效;除(chu)此(ci)之外，三級(ji)站(zhan)(zhan)(zhan)和(he)(he)五級(ji)站(zhan)(zhan)(zhan)的集中化電(dian)(dian)(dian)(dian)(dian)(dian)磁波輻射溶解為(wei)多(duo)一點輻射源;因為(wei)不(bu)一樣容積(ji)箱(xiang)變電(dian)(dian)(dian)(dian)(dian)(dian)器的土(tu)建工(gong)程基本(ben)不(bu)一樣，箱(xiang)變容積(ji)不(bu)方便;當箱(xiang)變負(fu)載或客戶容積(ji)提(ti)(ti)升時(shi)(shi)，土(tu)建工(gong)程必須(xu)復建，斷電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)長，提(ti)(ti)升工(gong)程項(xiang)目難度系數。　　

歐(ou)式(shi)(shi)(shi)古典(dian)箱(xiang)式(shi)(shi)(shi)變(bian)(bian)壓器(qi)的特點是(shi)(shi)噪聲相當于三型站和(he)一(yi)型站，輻射源小(xiao)于美式(shi)(shi)(shi)箱(xiang)式(shi)(shi)(shi)變(bian)(bian)壓器(qi)，由(you)于歐(ou)式(shi)(shi)(shi)古典(dian)箱(xiang)式(shi)(shi)(shi)變(bian)(bian)壓器(qi)在金屬材料箱(xiang)里具有(you)攔(lan)截功效，可以設定配電自(zi)動(dong)化，不(bu)(bu)但(dan)具備(bei)(bei)三型站和(he)一(yi)型站的優勢(shi)，并且具備(bei)(bei)美式(shi)(shi)(shi)箱(xiang)式(shi)(shi)(shi)變(bian)(bian)壓器(qi)的具體(ti)優勢(shi)。但(dan)不(bu)(bu)足之(zhi)處是(shi)(shi)容積大，不(bu)(bu)利安(an)裝，對(dui)社區環境合理布局有(you)一(yi)定危害。　　

一般(ban)來說(shuo)，美國和歐洲都是有(you)各種各樣缺陷，但由于(yu)科(ke)學技術(shu)的(de)(de)(de)發展、配(pei)電(dian)(dian)自動(dong)化、電(dian)(dian)容補償等前(qian)沿技術(shu)的(de)(de)(de)持續(xu)運(yun)用，箱變(bian)將替代傳統(tong)的(de)(de)(de)的(de)(de)(de)土房配(pei)電(dian)(dian)站，變(bian)成(cheng)供電(dian)(dian)系統(tong)不可(ke)缺少的(de)(de)(de)構成(cheng)部(bu)分。
