變壓(ya)(ya)器(qi)(qi)(qi)運(yun)(yun)抵現場和(he)運(yun)(yun)行(xing)(xing)期間(jian)一般不進(jin)行(xing)(xing)吊芯檢修(xiu)，這就要(yao)求變壓(ya)(ya)器(qi)(qi)(qi)的(de)(de)(de)(de)質量應有可靠(kao)的(de)(de)(de)(de)保證。隨著變壓(ya)(ya)器(qi)(qi)(qi)制造水平的(de)(de)(de)(de)提高(gao)，密封式(shi)結(jie)構也逐漸被采用，目前國(guo)內外的(de)(de)(de)(de)一些大型變壓(ya)(ya)器(qi)(qi)(qi)也已開(kai)始采用這種結(jie)構。當(dang)變壓(ya)(ya)器(qi)(qi)(qi)的(de)(de)(de)(de)器(qi)(qi)(qi)身需要(yao)進(jin)行(xing)(xing)檢修(xiu)時，可以(yi)將整個變壓(ya)(ya)器(qi)(qi)(qi)帶(dai)油(you)(you)搬(ban)運(yun)(yun)至有起重設備(bei)的(de)(de)(de)(de)場所，將箱(xiang)蓋打開(kai)，吊出器(qi)(qi)(qi)身，進(jin)行(xing)(xing)檢修(xiu)。變壓(ya)(ya)器(qi)(qi)(qi)油(you)(you)箱(xiang)(波紋油(you)(you)箱(xiang))就是裝滿油(you)(you)的(de)(de)(de)(de)，安慶變壓(ya)(ya)器(qi)(qi)(qi)油(you)(you)箱(xiang)加(jia)工，只(zhi)是變壓(ya)(ya)器(qi)(qi)(qi)的(de)(de)(de)(de)油(you)(you)枕中(zhong)(zhong)油(you)(you)不能太滿。 油(you)(you)箱(xiang)與油(you)(you)枕通過(guo)管道(dao)連接，當(dang)油(you)(you)箱(xiang)中(zhong)(zhong)缺少油(you)(you)時，油(you)(you)枕中(zhong)(zhong)的(de)(de)(de)(de)油(you)(you)就會順管道(dao)流下。

變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)油(you)(you)箱應(ying)裝有(you)下列(lie)閥(fa)(fa)門：①變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)主(zhu)油(you)(you)箱、儲油(you)(you)柜的(de)排污(wu)閥(fa)(fa)；②取油(you)(you)樣閥(fa)(fa)（取油(you)(you)樣閥(fa)(fa)應(ying)具有(you)8mm以上(shang)的(de)內螺紋(wen)并配有(you)可取下的(de)栓塞）我國電力變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)多為(wei)油(you)(you)浸式變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)，多年來(lai)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)滲漏油(you)(you)現象時有(you)發生，嚴重的(de)滲漏不但降低(di)了變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)使用壽命，大型(xing)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)油(you)(you)箱加(jia)工，影響系統的(de)安全、穩(wen)定(ding)運行。對(dui)于不同(tong)型(xing)號和(he)不同(tong)容(rong)量的(de)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)，無論是(shi)采用法蘭連接還(huan)是(shi)螺紋(wen)連接，更(geng)換(huan)密封件(jian)前必須(xu)先清除連接面上(shang)的(de)塵土和(he)銹跡。
