變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)油(you)(you)枕安(an)裝在(zai)(zai)(zai)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的油(you)(you)箱(波紋(wen)油(you)(you)箱)上，還有一個用(yong)(yong)(yong)“玻璃”封閉的管(guan)道，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)油(you)(you)箱加工(gong)廠(chang)家，叫“防爆管(guan)”，就是防止變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)故障時，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)油(you)(you)箱加工(gong)的價格，油(you)(you)溫快速(su)。油(you)(you)箱的作(zuo)用(yong)(yong)(yong)：油(you)(you)箱是變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的外殼(ke)，內裝鐵芯和繞組(zu)并(bing)充滿變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)油(you)(you)，使鐵芯和繞組(zu)浸(jin)在(zai)(zai)(zai)油(you)(you)內。變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)油(you)(you)起(qi)絕緣和散熱(re)作(zuo)用(yong)(yong)(yong)。一般大型變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)均(jun)采用(yong)(yong)(yong)鐘罩式油(you)(you)箱，這種變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的器(qi)(qi)身自重都(dou)在(zai)(zai)(zai)200t以上，總(zong)重量均(jun)在(zai)(zai)(zai)300t以上，運輸起(qi)來比較困難。當進行(xing)器(qi)(qi)身檢修時，不必吊出笨(ben)重的器(qi)(qi)身，只要吊去較輕的箱殼(ke)，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)油(you)(you)箱加工(gong)廠(chang)，即(ji)可進行(xing)檢修工(gong)作(zuo)。

箱(xiang)(xiang)(xiang)式(shi)油(you)箱(xiang)(xiang)(xiang)壁(bi)用(yong)鋼板(ban)彎折成型(xing)，截(jie)面多為橢圓形或(huo)長方形，蘇州(zhou)變壓(ya)(ya)(ya)器油(you)箱(xiang)(xiang)(xiang)加工，箱(xiang)(xiang)(xiang)沿和箱(xiang)(xiang)(xiang)蓋之間(jian)放置密封膠墊，然后用(yong)固(gu)定螺栓加以密封。箱(xiang)(xiang)(xiang)式(shi)油(you)箱(xiang)(xiang)(xiang)用(yong)于中、小型(xing)變壓(ya)(ya)(ya)器。這種變壓(ya)(ya)(ya)器上(shang)部箱(xiang)(xiang)(xiang)蓋可以打開，其(qi)充油(you)后總(zong)重量(liang)與大型(xing)變壓(ya)(ya)(ya)器相比不算太(tai)重。波紋片或(huo)者焊(han)接到油(you)箱(xiang)(xiang)(xiang)箱(xiang)(xiang)(xiang)體上(shang)或(huo)者是螺栓連接到箱(xiang)(xiang)(xiang)體上(shang)之后，把油(you)箱(xiang)(xiang)(xiang)蓋裝(zhuang)上(shang)油(you)箱(xiang)(xiang)(xiang)，把箱(xiang)(xiang)(xiang)蓋上(shang)的所有(you)孔堵(du)死，保留(liu)一個油(you)位計或(huo)者是壓(ya)(ya)(ya)力孔安裝(zhuang)上(shang)氣(qi)表或(huo)是壓(ya)(ya)(ya)力表。

如何對變(bian)(bian)壓(ya)(ya)器(qi)油(you)(you)箱(xiang)(xiang)檢漏方(fang)法：油(you)(you)箱(xiang)(xiang)檢漏也稱試漏，常用(yong)的有(you)水(shui)試和氣試兩(liang)種(zhong)；是(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)油(you)(you)箱(xiang)(xiang)生產廠家試驗油(you)(you)箱(xiang)(xiang)是(shi)(shi)否合格(ge)的方(fang)法。油(you)(you)箱(xiang)(xiang)底部(bu)兩(liang)對角處應(ying)設有(you)兩(liang)塊(kuai)供油(you)(you)箱(xiang)(xiang)接(jie)地的端子(zi)（變(bian)(bian)壓(ya)(ya)器(qi)油(you)(you)箱(xiang)(xiang)即外(wai)殼接(jie)地主要是(shi)(shi)為了保障人(ren)身安(an)全。當變(bian)(bian)壓(ya)(ya)器(qi)的絕緣損壞時，變(bian)(bian)壓(ya)(ya)器(qi)外(wai)殼就會帶電。變(bian)(bian)壓(ya)(ya)器(qi)油(you)(you)箱(xiang)(xiang)應(ying)裝有(you)下(xia)(xia)列閥門：①變(bian)(bian)壓(ya)(ya)器(qi)主油(you)(you)箱(xiang)(xiang)、儲油(you)(you)柜的排污閥；②取油(you)(you)樣閥（取油(you)(you)樣閥應(ying)具有(you)8mm以(yi)上的內螺(luo)紋(wen)并(bing)配有(you)可取下(xia)(xia)的栓塞）
