波紋片或(huo)者(zhe)焊接到油(you)(you)(you)箱(xiang)(xiang)(xiang)(xiang)箱(xiang)(xiang)(xiang)(xiang)體上(shang)(shang)或(huo)者(zhe)是螺栓(shuan)連接到箱(xiang)(xiang)(xiang)(xiang)體上(shang)(shang)之后，把油(you)(you)(you)箱(xiang)(xiang)(xiang)(xiang)蓋裝(zhuang)上(shang)(shang)油(you)(you)(you)箱(xiang)(xiang)(xiang)(xiang)，把箱(xiang)(xiang)(xiang)(xiang)蓋上(shang)(shang)的所有孔堵死(si)，保留一(yi)個油(you)(you)(you)位計(ji)或(huo)者(zhe)是壓(ya)力孔安(an)裝(zhuang)上(shang)(shang)氣表或(huo)是壓(ya)力表。上(shang)(shang)節(jie)油(you)(you)(you)箱(xiang)(xiang)(xiang)(xiang)做成鐘罩形，下(xia)節(jie)油(you)(you)(you)箱(xiang)(xiang)(xiang)(xiang)一(yi)般為槽(cao)形箱(xiang)(xiang)(xiang)(xiang)底或(huo)平板(ban)式箱(xiang)(xiang)(xiang)(xiang)底，上(shang)(shang)、下(xia)節(jie)油(you)(you)(you)箱(xiang)(xiang)(xiang)(xiang)用螺栓(shuan)連接在一(yi)起，中間力口放密封膠墊。下(xia)節(jie)油(you)(you)(you)箱(xiang)(xiang)(xiang)(xiang)還(huan)裝(zhuang)設放油(you)(you)(you)閥(fa)門(men)和(he)油(you)(you)(you)樣閥(fa)門(men)。一(yi)臺31500kVA變(bian)壓(ya)器(qi)的總(zong)焊點達70余(yu)處，焊縫總(zong)長近(jin)20m左右，因(yin)此滲(shen)漏途徑(jing)可能較(jiao)多。直接滲(shen)漏的原因(yin)是橡(xiang)膠密封件失效和(he)焊縫開裂、氣孔、夾渣等。

常見(jian)的變壓器(qi)油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)按其容量的大小，有(you)箱(xiang)(xiang)(xiang)式油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)、鐘罩式油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)和密封式油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)3種基本型式。(1)箱(xiang)(xiang)(xiang)式油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)（吊芯式油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)）。變壓器(qi)在制造過程，摩(mo)托車油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)加(jia)工，油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)焊(han)(han)點(dian)多、焊(han)(han)縫(feng)長、焊(han)(han)接難、焊(han)(han)接材料、焊(han)(han)接(焊(han)(han)接工藝(yi)裝備的分(fen)類特點(dian))規范、工藝(yi)、技(ji)術等都會影響焊(han)(han)接質量，造成氣(qi)孔、砂眼、虛焊(han)(han)、脫焊(han)(han)現象(xiang)從而使變壓器(qi)滲漏油(you)(you)(you)(you)。 當(dang)變壓器(qi)的器(qi)身需要(yao)進行檢修時(shi)，可以將整個(ge)變壓器(qi)帶油(you)(you)(you)(you)搬運至有(you)起重設備的場所，油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)加(jia)工廠，將箱(xiang)(xiang)(xiang)蓋打開，油(you)(you)(you)(you)箱(xiang)(xiang)(xiang)加(jia)工，吊出器(qi)身，進行檢修。

變壓(ya)器(qi)油(you)(you)(you)(you)箱(xiang)(xiang)外(wai)殼(ke)接(jie)(jie)地(di)(di)(di)對接(jie)(jie)地(di)(di)(di)裝置(zhi)的要(yao)求：①接(jie)(jie)地(di)(di)(di)體與(yu)接(jie)(jie)地(di)(di)(di)線應(ying)(ying)焊接(jie)(jie)牢(lao)固。②接(jie)(jie)地(di)(di)(di)電(dian)(dian)阻(zu)應(ying)(ying)不大于(yu)0.5Ω，地(di)(di)(di)線與(yu)設備應(ying)(ying)可靠連接(jie)(jie)。③圓鋼接(jie)(jie)地(di)(di)(di)體直徑應(ying)(ying)符合(he)有關規定。油(you)(you)(you)(you)箱(xiang)(xiang)底部兩對角處應(ying)(ying)設有兩塊供油(you)(you)(you)(you)箱(xiang)(xiang)接(jie)(jie)地(di)(di)(di)的端子(zi)（變壓(ya)器(qi)油(you)(you)(you)(you)箱(xiang)(xiang)即外(wai)殼(ke)接(jie)(jie)地(di)(di)(di)主要(yao)是(shi)(shi)為了保(bao)障(zhang)人身安全。當變壓(ya)器(qi)的絕緣損壞(huai)時，變壓(ya)器(qi)外(wai)殼(ke)就(jiu)會帶(dai)電(dian)(dian)。變壓(ya)器(qi)油(you)(you)(you)(you)箱(xiang)(xiang)(波紋油(you)(you)(you)(you)箱(xiang)(xiang))豎直設計是(shi)(shi)為了使冷卻(que)油(you)(you)(you)(you)依靠自身密度的變化(由于(yu)溫度變化導致的)形成(cheng)對流，提(ti)高散熱(re)效率。變壓(ya)器(qi)油(you)(you)(you)(you)箱(xiang)(xiang)(波紋油(you)(you)(you)(you)箱(xiang)(xiang))散熱(re)管里(li)面(mian)要(yao)有冷卻(que)油(you)(you)(you)(you)，是(shi)(shi)管道形的。
