style="text-indent:25px">變壓器變比測試儀常見故障：變比測試的目的及意義：（1）檢查變比是否與銘牌相符，以保證對電壓的正確變換。（2）檢查分接開關(guān)的位置是否正確。（3）在變壓器發(fā)生故障后，通過測量變比來檢查繞組匝間是否存在匝間短路，開路（交接和大修）。（4）測出三相變壓器本身變比的不平衡程度，確定零序分量的大小。（5）準(zhǔn)確獲得變比，判斷變壓器是否可以并聯(lián)運(yùn)行。當(dāng)兩臺并列運(yùn)行的變壓器二次側(cè)空載電壓相差為額定電壓的1%時，兩臺變壓器繞組中環(huán)流將達(dá)到額定電流的10%左右時，會增加變壓器的損耗，占據(jù)變壓器的容量。因此變比的差值應(yīng)限制在一定范圍之內(nèi)目前常見的變比測試儀（需要輸入一些銘牌上的數(shù)據(jù)，一般輸入額定電壓，額定分接比，檔位數(shù)），一般電源需要供給220V市電。較新的智能變比測試儀器（盲測無需輸入任何參數(shù)即可測試），采用新的單片機(jī)，內(nèi)部有鋰電池供電，支持?jǐn)?shù)據(jù)存儲及U盤轉(zhuǎn)存，實(shí)現(xiàn)打印等微機(jī)處理。在線圈溫度穩(wěn)定的情況下進(jìn)行測量，要求變壓器油箱上、下部的溫度之差不超過３℃。</p><div

變壓器是一種相對靜止的電氣設(shè)備，由繞在同一個鐵心上的兩個或兩個以上的繞組組成的，繞組之間通過交變的磁通的相互聯(lián)系。為了把發(fā)電廠發(fā)出的電能經(jīng)濟(jì)的傳輸、合理的分配以及安全的使用，都要用到電力變壓器。 </p> <p> 2、變壓器工作原理 </p> <p> 簡單說變壓器的工作原理就是“電生磁，磁生電”。變壓器的初級（一次）線圈和次級（二次）線圈共同繞在一個鐵芯上，當(dāng)一次線圈通入電壓U1后，在鐵芯中產(chǎn)生交變磁通，這個磁通穿過一次繞組和二次繞組，根據(jù)電磁感應(yīng)定律，在一次繞組和二次繞組中分別產(chǎn)生感應(yīng)電勢E1和E2。根據(jù)電磁感應(yīng)定律可知，一次側(cè)、二次側(cè)繞組的感應(yīng)電勢分別為：E1/E2=U1/U2=N1/N2=K(k為變比) </p> <p> <br /> 儀器可以由用戶預(yù)設(shè)40組被試品參數(shù)，而且這些參數(shù)可以根據(jù)需要隨時刪除和增加。上海電子變壓器局放檢測系統(tǒng)</p><p style="text-indent:25px">變壓器是利用電磁感應(yīng)原理，從一個電路向另一個電路傳遞電能或傳輸信號的一種電器。上海電子變壓器局放檢測系統(tǒng)</p><p style="text-indent:25px">對于變壓器絕緣在線檢測zui有效的方法之一是監(jiān)測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。在線測量時,由于受現(xiàn)場干擾信號的影響,直接測量局部放電高頻參量較為困難,且對運(yùn)行設(shè)備在進(jìn)行在線監(jiān)測采集所需信號時應(yīng)盡量不改變原設(shè)備的運(yùn)行接線狀態(tài)。因此,將信號取樣點(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影響變壓器的正常運(yùn)行。但傳感器選在鐵芯接地點(diǎn)時,對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。上海電子變壓器局放檢測系統(tǒng)</p><p
