style="text-indent:25px">物質(zhì)介紹：在電器設(shè)備和無線電路中，[1]變壓器常用作升降電壓、匹配阻抗，安全隔離等。在發(fā)電機中，不管是線圈運動通過磁場或磁場運動通過固定線圈，均能在線圈中感應(yīng)電勢，此兩種情況，磁通的值均不變，但與線圈相交鏈的磁通數(shù)量卻有變動，這是互感應(yīng)的原理。變壓器就是一種利用電磁互感應(yīng)，變換電壓，電流和阻抗的器件。變壓器的較基本形式，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。當一交流電流（具有某一已知頻率）流于其中之一組線圈時，于另一組線圈中將感應(yīng)出具有相同頻率之交流電壓，而感應(yīng)的電壓大小取決于兩線圈耦合及磁交鏈之程度。四川電子變壓器測試臺儀器在運輸、儲存及工作中應(yīng)避免強烈震動、陽光直射和磁場的影響。</p><div

儀器體積小、重量輕至2.5kg,接線簡單、操作方便、測量準確、穩(wěn)定性好。變比測試儀能同時測量單相或三相電力變壓器的交流電壓有效值，電壓平均值、有效值、有功功率、功率因素和頻率等電量參數(shù)，測量精度為0.1級，智能化、專業(yè)化設(shè)計、適用于電力變壓器空載、負載、感應(yīng)等試驗的測試。高壓變壓器容量測試儀容量測量范圍：20k VA~100000k

首先選擇變壓器的額定電壓。高壓側(cè)電壓與所接入電網(wǎng)電壓相等，低壓側(cè)電壓比低壓側(cè)電網(wǎng)的電壓高10%或5%（取決變壓器電壓等級和阻抗電壓大?。活~定容量選擇。計算變壓器所帶負荷的大小（要求統(tǒng)計比較大綜合負荷，將有功負荷kW值換算成視在功率kVA），如果是兩臺變壓器，那么每臺變壓器的容量可按照比較大綜合負荷的70%選擇，一臺變壓器要按總負荷考慮，并留有適當?shù)脑６?。其它明星參?shù)可結(jié)合變壓器產(chǎn)品適當考慮。例如：選擇35/10kV變壓器。假定比較大負荷為3500kW，功率因數(shù)為，選兩臺變壓器，容量S=×3500/，可選擇3150kVA的變壓器，電壓比為35kV/。再從產(chǎn)品目錄中選擇型號。變壓器的生產(chǎn)研發(fā)是非常復(fù)雜的，一般生產(chǎn)變壓器的廠家都是技術(shù)水平比較高的。</p><div

style="text-indent:25px">變壓器滲漏油的原因分析：1、變壓器的制造質(zhì)量變壓器在制造過程中，油箱焊點多、焊縫長、焊接難、焊接材料、焊接規(guī)范、工藝、技術(shù)等都會影響焊接質(zhì)量，造成氣孔、砂眼、虛焊、脫焊現(xiàn)象從而使變壓器滲漏油。2、板式蝶閥質(zhì)量欠佳變壓器另外一個經(jīng)常發(fā)生滲漏的部位在板式蝶閥處，較早前生產(chǎn)的變壓器，使用的普通板式蝶閥連接面比較粗糙、單薄，單層密封，屬淘汰產(chǎn)品，極易引起變壓器滲漏油。3、安裝方法不當法蘭連接處不平，安裝時密封墊四周不能均勻受力，人為造成密封墊四周螺栓非均勻受力；法蘭接頭變形錯位，使密封墊一側(cè)受力偏大，一側(cè)受力偏小，受力偏小的一側(cè)密封墊因壓縮量不足就容易引起滲漏。此現(xiàn)象多發(fā)生在瓦斯繼電器連接處及散熱器與本體連接處；還有一點就是密封墊安裝時，其壓縮量不足或過大，壓縮量不足時，變壓器運行溫度升高油變稀，造成變壓器滲油，壓縮量偏大，密封墊變形嚴重，老化加速使用壽命縮短。四川電子變壓器測試臺</p></p><br
