style="text-indent:25px">對(duì)于變壓器絕緣在線檢測(cè)zui有效的方法之一是監(jiān)測(cè)局部放電電脈沖參量。變壓器正常運(yùn)行中局部放電量較小,近年生產(chǎn)的110kV以上變壓器局部放電量都控制在500pC以下;但在實(shí)際運(yùn)行中,即使出現(xiàn)有5000pC左右的放電也照常運(yùn)行,其絕緣缺陷發(fā)展過程可能延續(xù)幾周甚至幾年。在線測(cè)量時(shí),由于受現(xiàn)場干擾信號(hào)的影響,直接測(cè)量局部放電高頻參量較為困難,且對(duì)運(yùn)行設(shè)備在進(jìn)行在線監(jiān)測(cè)采集所需信號(hào)時(shí)應(yīng)盡量不改變?cè)O(shè)備的運(yùn)行接線狀態(tài)。因此,將信號(hào)取樣點(diǎn)選擇在變壓器鐵芯接地引出線和中性點(diǎn)引出線以及高壓套管末屏引出線處,是非常有效及合理的。在任何情況下它不會(huì)影響變壓器的正常運(yùn)行。但傳感器選在鐵芯接地點(diǎn)時(shí),對(duì)傳感器和放大器的靈敏度要求比選在套管末屏取樣要求更高。肇慶電子變壓器極性測(cè)試測(cè)量變壓器低壓側(cè)時(shí)，所有人員應(yīng)與高壓側(cè)保持適當(dāng)安全距離。</p><div

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(diǎn)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(tái)31500kVA變壓器的總焊點(diǎn)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。</p><p style="text-indent:25px">變壓器是借助于電磁感應(yīng),在繞組之間交換交流電壓或電流的一種電氣設(shè)備。從電廠發(fā)出的電能,要經(jīng)過很長的輸電線路輸送給遠(yuǎn)方的用戶，為了減少輸電線路上的電能損耗,必須采用高壓或超高壓輸送。而目前一般發(fā)電廠發(fā)出的電壓,由于受到絕緣水平的限制，電壓不能太高,這就要經(jīng)過變壓器將電廠發(fā)壓進(jìn)行升高送到電力網(wǎng)。這種變壓器統(tǒng)稱升壓變壓器。對(duì)各用戶來說,各種電氣設(shè)備所要求的電壓又不太高,也要經(jīng)過變壓器，將電力系統(tǒng)的高電壓變成符合用戶各種電氣設(shè)備要求的額定電壓。作為這種用途的變壓器統(tǒng)稱降壓器。電力變壓器是電力系統(tǒng)中，用以改變電壓的主要電氣設(shè)備。變壓器的基本型式，包括兩組繞有導(dǎo)線之線圈，并且彼此以電感方式稱合一起。</p><div
