變(bian)(bian)(bian)壓器(qi)(qi)(qi)滲漏油(you)(you)(you)(you)，橡膠密封(feng)件失效和(he)焊(han)縫開裂 ，變(bian)(bian)(bian)壓器(qi)(qi)(qi)的(de)(de)焊(han)點多、焊(han)縫長，變(bian)(bian)(bian)壓器(qi)(qi)(qi)油(you)(you)(you)(you)箱(xiang)(xiang)加工廠家，而(er)油(you)(you)(you)(you)浸式(shi)變(bian)(bian)(bian)壓器(qi)(qi)(qi)是以(yi)(yi)(yi)(yi)鋼板焊(han)接殼(ke)體(ti)為基礎的(de)(de)多種焊(han)接和(he)連(lian)接的(de)(de)集合體(ti)。 一般大型變(bian)(bian)(bian)壓器(qi)(qi)(qi)均(jun)采(cai)用(yong)鐘罩(zhao)式(shi)油(you)(you)(you)(you)箱(xiang)(xiang)，這種變(bian)(bian)(bian)壓器(qi)(qi)(qi)的(de)(de)器(qi)(qi)(qi)身自重(zhong)(zhong)都在(zai)200t以(yi)(yi)(yi)(yi)上，總重(zhong)(zhong)量(liang)均(jun)在(zai)300t以(yi)(yi)(yi)(yi)上，運輸起來比較困難。當進行器(qi)(qi)(qi)身檢(jian)修時，不(bu)必吊(diao)出笨重(zhong)(zhong)的(de)(de)器(qi)(qi)(qi)身，只要(yao)吊(diao)去較輕的(de)(de)箱(xiang)(xiang)殼(ke)，即可進行檢(jian)修工作(zuo)。油(you)(you)(you)(you)箱(xiang)(xiang)頂(ding)部應帶有(you)(you)斜(xie)坡，變(bian)(bian)(bian)壓器(qi)(qi)(qi)油(you)(you)(you)(you)箱(xiang)(xiang)加工工藝(yi)，以(yi)(yi)(yi)(yi)便泄(xie)水和(he)將氣(qi)體(ti)積聚(ju)通向氣(qi)體(ti)繼電(dian)器(qi)(qi)(qi)。油(you)(you)(you)(you)箱(xiang)(xiang)頂(ding)部的(de)(de)所(suo)有(you)(you)開孔均(jun)應有(you)(you)凸(tu)起的(de)(de)法(fa)蘭盤(pan)。

大型變壓(ya)(ya)(ya)器(qi)一般(ban)有(you)(you)兩(liang)個油(you)(you)箱(xiang)(xiang)(xiang)，一個為本體(ti)油(you)(you)箱(xiang)(xiang)(xiang)；一個為有(you)(you)載凋壓(ya)(ya)(ya)油(you)(you)箱(xiang)(xiang)(xiang)，有(you)(you)載調壓(ya)(ya)(ya)油(you)(you)箱(xiang)(xiang)(xiang)內裝有(you)(you)分接(jie)(jie)開(kai)關。因此(ci)設一個單(dan)獨(du)(du)的油(you)(you)箱(xiang)(xiang)(xiang)將分接(jie)(jie)開(kai)關單(dan)獨(du)(du)放置(zhi)。變壓(ya)(ya)(ya)器(qi)油(you)(you)箱(xiang)(xiang)(xiang)外殼接(jie)(jie)地(di)對接(jie)(jie)地(di)裝置(zhi)的要(yao)求(qiu)：①接(jie)(jie)地(di)體(ti)與接(jie)(jie)地(di)線(xian)(xian)應(ying)(ying)焊接(jie)(jie)牢固。②接(jie)(jie)地(di)電阻應(ying)(ying)不大于0.5Ω，地(di)線(xian)(xian)與設備應(ying)(ying)可靠連(lian)接(jie)(jie)。③圓鋼接(jie)(jie)地(di)體(ti)直(zhi)徑應(ying)(ying)符合(he)有(you)(you)關規定(ding)。我國電力變壓(ya)(ya)(ya)器(qi)多為油(you)(you)浸式(shi)變壓(ya)(ya)(ya)器(qi)，變壓(ya)(ya)(ya)器(qi)油(you)(you)箱(xiang)(xiang)(xiang)加工(gong)廠，多年來變壓(ya)(ya)(ya)器(qi)滲漏(lou)油(you)(you)現象時有(you)(you)發生，嚴(yan)重的滲漏(lou)不但降低(di)了(le)變壓(ya)(ya)(ya)器(qi)的使用壽命，影(ying)響系統的安全、穩定(ding)運行。

箱(xiang)(xiang)式油(you)(you)箱(xiang)(xiang)用(yong)于中、小型變壓(ya)器(qi)。這種變壓(ya)器(qi)上部箱(xiang)(xiang)蓋可以打開(kai)，南(nan)京變壓(ya)器(qi)油(you)(you)箱(xiang)(xiang)加(jia)工，其充(chong)油(you)(you)后(hou)總重(zhong)量與(yu)大型變壓(ya)器(qi)相比不(bu)算太重(zhong)。油(you)(you)箱(xiang)(xiang)的(de)作用(yong)：油(you)(you)箱(xiang)(xiang)是變壓(ya)器(qi)的(de)外殼，內裝鐵芯和(he)繞組并充(chong)滿變壓(ya)器(qi)油(you)(you)，使(shi)鐵芯和(he)繞組浸在油(you)(you)內。變壓(ya)器(qi)油(you)(you)起(qi)絕緣和(he)散熱(re)作用(yong)。變壓(ya)器(qi)滲漏多發生在連接處，而(er)95 %以上主(zhu)要(yao)是由密封(feng)膠件(jian)引起(qi)的(de)。密封(feng)膠件(jian)質量的(de)好壞主(zhu)要(yao)取決(jue)于它的(de)耐油(you)(you)性(xing)能，耐油(you)(you)性(xing)能較(jiao)差的(de)，老化速度就較(jiao)快(kuai)。
