style="text-indent:25px">變壓器滲漏油的原因分析：1、橡膠密封件失效和焊縫開裂變壓器的焊點多、焊縫長，而油浸式變壓器是以鋼板焊接殼體為基礎(chǔ)的多種焊接和連接的體。一臺31500kVA變壓器的總焊點達(dá)70余處，焊縫總長近20m左右，因此滲漏途徑可能較多。直接滲漏的原因是橡膠密封件失效和焊縫開裂、氣孔、夾渣等。2、密封膠件老化、龜裂、變形變壓器滲漏多發(fā)生在連接處，而95 %以上主要是由密封膠件引起的。密封膠件質(zhì)量的好壞主要取決于它的耐油性能，耐油性能較差的，老化速度就較快，特別是在高溫下，其老化速度就更快，極易引起密封件老化、龜裂，變質(zhì)、變形，以至失效，造成變壓器滲漏油。深圳變壓器特性測試臺可測量變壓器的空載電流、空載損耗、短路電壓、短路（負(fù)載）損耗。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海電子變壓器檢測設(shè)備,變壓器" src="https://tyunfile.71360.com/UploadFile/ZRX888/637284368129267578/9378652.png"></div><p> 變壓器據(jù)主要用途，可分成電力工程變壓器和**型變壓器（爐壁變壓器、整流器變壓器、直流實驗變壓器等），電壓調(diào)節(jié)器、礦用防變壓器、聲頻變壓器、高頻變壓器、高頻率變壓器、沖擊性變壓器、儀表盤變壓器、電子器件變壓器、串聯(lián)電抗器、變壓器等）。電磁灶是一種運用電流的磁效應(yīng)加溫基本原理生產(chǎn)制造的電炊具。它由高頻率電磁感應(yīng)加熱電磁線圈（即勵磁線圈）、高頻率輸出功率變換設(shè)備、控制板和磁鐵原材料底鍋構(gòu)成。加熱爐和電磁灶內(nèi)的加溫電磁線圈板構(gòu)成高頻率變壓器。內(nèi)部電磁線圈是變壓器的關(guān)鍵一部分，主次一部分是加熱爐。當(dāng)內(nèi)部一次加溫電磁線圈板有交流電流輸出時，必定會在二次爐墻上造成感應(yīng)電動勢，根據(jù)爐墻自身的電阻器造成發(fā)熱量（因此加熱爐自身也是一個負(fù)載）。變壓器歸類。原理：變壓器是一種轉(zhuǎn)換交流電流、交流電路和特性阻抗的設(shè)備。當(dāng)一次電磁線圈中有交流電路時，鐵芯（或鐵芯）會造成溝通交流磁通量，進(jìn)而在二次電磁線圈中造成工作電壓（或電流量）。變壓器由變壓器鐵芯（或變壓器骨架）和電磁線圈構(gòu)成。電磁線圈有兩個或2個之上的繞阻，在其中聯(lián)接到開關(guān)電源的繞阻稱之為一次電磁線圈，其他的稱之為二次電磁線圈。變壓器歸類：電容器。 </p> <p> </p><p style="text-indent:25px">零序阻抗測試：一臺變壓器的零序電壓和零序電流所表現(xiàn)出的阻抗叫零序阻抗。當(dāng)系統(tǒng)不對稱運行時，就會產(chǎn)生零序電流。它的大小不與繞組的連接方式有關(guān)，還與鐵芯結(jié)構(gòu)有關(guān)。用單相調(diào)壓器作為試驗電源，將調(diào)壓器的一個輸出端接到損耗測試儀的A相電流端子的正端，另一個輸出端接到測試儀C相電流端子的負(fù)端；黃色測試鉗的粗線接到測試儀的A相電流端子的負(fù)端，電壓測試線接到A相電壓端子；紅色測試鉗的粗線接到測試儀C相電流端子的負(fù)端（即與調(diào)壓器的輸出接到一起），細(xì)線接到測試儀的B相電壓端子上。再將被測變壓器的Yn側(cè)接線方式的A、B、C相接線柱短接到一起，并連接黃色測試鉗；0相接線柱連接到紅色測試鉗。注意一定要良好短接，否則會影響測試數(shù)據(jù)。變壓器外殼焊接不嚴(yán)密或膠墊不實都可能導(dǎo)致變壓器漏油，所以在維護的時候一定要非常注意。</p><div

style="text-indent:25px">變壓器直流電阻試驗及實驗儀器：試驗介紹：測量直流電阻的目是檢查電氣設(shè)備繞組或線圈的質(zhì)量及回路的完整性，以發(fā)現(xiàn)制造或運行中因振動而產(chǎn)生的機械應(yīng)力等原因所造成的導(dǎo)線斷裂、接頭開焊、接觸不良、匝間短路等缺陷。試驗設(shè)備：10A直流電阻測試儀被試設(shè)10KV/1000kVA油浸式變壓器（高壓側(cè)為三角形接法，低壓側(cè)星形接法）試驗方法：試驗接線：高壓側(cè)：AB/AC/BC,低壓側(cè)：AO/BO/CO1、測量前的準(zhǔn)備：首先將電源線以及地線可靠連接到直阻儀上，然后把隨機附帶的測試線連接到直阻儀面板與其顏色相對應(yīng)的輸入輸出接線端子上，將測試線末端的測試鉗夾到待測變壓器繞組兩端，并用力摩擦接觸點，以確保接觸良好。在變壓器的日常維護時需要注意觀察外觀，主要檢查變壓器外部是否存在滲油、是否存在零部件冒煙或放電現(xiàn)象。安微局放試驗變壓器</p><p
