變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)運行一(yi)(yi)段時間里(li)面(mian)(mian)會變(bian)(bian)(bian)(bian)得非常(chang)干燥，就(jiu)像(xiang)人體缺(que)水一(yi)(yi)樣(yang)。所以這個時候就(jiu)要及時給變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)補充油(you)，就(jiu)是(shi)(shi)(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)油(you)。這樣(yang)能保證變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)正常(chang)運行。可能有(you)(you)(you)人問(wen)缺(que)油(you)干燥是(shi)(shi)(shi)怎(zen)么(me)回事?因為(wei)每種變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)里(li)面(mian)(mian)都(dou)是(shi)(shi)(shi)有(you)(you)(you)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)油(you)的(de)，不僅(jin)僅(jin)油(you)浸(jin)式變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)里(li)有(you)(you)(you)，其它變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)都(dou)有(you)(you)(you)。變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)油(you)就(jiu)是(shi)(shi)(shi)保證變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)自行在(zai)正常(chang)進(jin)行輸(shu)送(song)電(dian)壓(ya)(ya)(ya)，另一(yi)(yi)方面(mian)(mian)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)油(you)也(ye)是(shi)(shi)(shi)給變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)供送(song)，就(jiu)像(xiang)人餓了要給他吃飯(fan)一(yi)(yi)樣(yang)，變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)“餓了”要給它輸(shu)送(song)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)油(you)。所以下(xia)面(mian)(mian)小編(bian)給大(da)家主(zhu)要介(jie)紹(shao)一(yi)(yi)下(xia)。

由于變(bian)(bian)壓(ya)器(qi)受(shou)短路沖(chong)擊后一(yi)般(ban)需要(yao)較長(chang)時間(jian)進(jin)行(xing)檢修，為(wei)防止變(bian)(bian)壓(ya)器(qi)受(shou)潮，可以(yi)采取(qu)兩種措施：在每(mei)天收工前將變(bian)(bian)壓(ya)器(qi)扣罩，使(shi)用(yong)真空(kong)泵對(dui)變(bian)(bian)壓(ya)器(qi)進(jin)行(xing)抽真空(kong)，以(yi)抽去變(bian)(bian)壓(ya)器(qi)器(qi)身表面(mian)的(de)游離水(shui)，開工時，使(shi)用(yong)干燥(zao)的(de)氮氣或(huo)干燥(zao)空(kong)氣解除(chu)真空(kong)，一(yi)般(ban)變(bian)(bian)壓(ya)器(qi)在檢修后熱油(you)循環24小時即可直接投入運(yun)行(xing);每(mei)天收工后，對(dui)變(bian)(bian)壓(ya)器(qi)采取(qu)防雨措施，在工作(zuo)全(quan)部完(wan)工后，對(dui)變(bian)(bian)壓(ya)器(qi)采用(yong)熱油(you)噴淋法(fa)進(jin)行(xing)干燥(zao)，這(zhe)種方法(fa)一(yi)般(ban)需要(yao)7-10天的(de)時間(jian)。

此(ci)外，在變(bian)壓(ya)(ya)(ya)器(qi)(qi)發生短路故(gu)障(zhang)后(hou)，除了按照常規(gui)項目(mu)對變(bian)壓(ya)(ya)(ya)器(qi)(qi)進行試驗外，應結合變(bian)壓(ya)(ya)(ya)器(qi)(qi)油、氣體(ti)繼電器(qi)(qi)內氣體(ti)、繞組(zu)(zu)直流電阻(zu)、繞組(zu)(zu)電容量、繞組(zu)(zu)變(bian)形(xing)測量的(de)試驗結果判斷分析故(gu)障(zhang)的(de)性質，并檢查繞組(zu)(zu)的(de)變(bian)形(xing)、鐵(tie)芯及夾件的(de)位(wei)移與松動情況(kuang)，然后(hou)確(que)定對變(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)處理(li)(li)方案及應采取的(de)預(yu)防措(cuo)施。在因變(bian)壓(ya)(ya)(ya)器(qi)(qi)短路故(gu)障(zhang)造成繞組(zu)(zu)嚴重(zhong)變(bian)形(xing)需要更換繞組(zu)(zu)時(shi)，應注意鐵(tie)芯芯片的(de)回裝、所有絕(jue)緣(yuan)件的(de)烘干(gan)、變(bian)壓(ya)(ya)(ya)器(qi)(qi)油的(de)處理(li)(li)及變(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)整體(ti)干(gan)燥。
