變壓器是應用，常見的電力設(shè)備之一。我們都知道變壓器是一種能將某一種電壓、電流、相數(shù)的交流電能轉(zhuǎn)變成另一種電壓、電流、相數(shù)的交流電能的電器。在生產(chǎn)和生活中，經(jīng)常會用到各種高低不同的電壓，比如工廠中常用的三相異步電動機的額定電壓是380V或220V；照明電路中要用220V；機床照明、行燈等只需要36V、24V，甚至更低的電壓。這就需要使用變壓器把同一交流電壓變換成頻率相同的不同等級的電壓，來滿足不同的使用要求。變壓器不僅能用于改變電壓，還可以用來改變電流（如變流器、大電流發(fā)生器等）、改變相位（如改變線圈的連接方法來改變變壓器的極性或組別）、變換阻抗（電子線路中的輸入、輸出變壓器）等。單相變壓器工作原理變壓器的基本工作原理是電磁感應原理。上圖所示為一個簡單的單相變壓器，安微變壓器綜合試驗臺，其基本結(jié)構(gòu)是在閉合的鐵芯上繞有兩個匝數(shù)不等的繞組（又稱線圈），繞組之間、鐵芯和繞組之間均相互絕緣，鐵芯由硅鋼片疊成?，F(xiàn)將匝數(shù)為W1的繞組與電源相連，稱該繞組為原繞組或初級繞組，匝數(shù)為W2的繞組通過開關(guān)K與負載相連，稱為副繞組或次級繞組。當接通電源，安微變壓器綜合試驗臺，把交流電壓U1加到原繞組上后，安微變壓器綜合試驗臺，交流電流l1流入該繞組，然后產(chǎn)生勵磁作用。變壓器發(fā)生不同性質(zhì)的故障，聲音會發(fā)生變化。這時應根據(jù)現(xiàn)場情采取措施，查找故障原因。安微變壓器綜合試驗臺</p><div

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?。?；額定容量選擇。計算變壓器所帶負荷的大?。ㄒ蠼y(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。浙江電子變壓器耐壓試驗儀通過質(zhì)量監(jiān)督標準,試驗變壓器用于對各種電氣產(chǎn)品、電器元件、絕緣材料等進行規(guī)定電壓下的絕緣強度試驗。</p><div

style="text-indent:25px">我們選擇試驗變壓器時，主要考慮以下幾點：（1）電壓。依據(jù)試品的要求，首先選用具有合適電壓的試驗變壓器，使試驗變壓器的高壓側(cè)額定電壓Un高于被試品的試驗電壓Us,即Un>Us。其次應檢查試驗變壓器所需的低壓側(cè)電壓，是否能和現(xiàn)場電源電壓，調(diào)壓器相匹配。（2）電流。試驗變壓器的額定輸出電流In應大于被試品所需的電流Is，即In>Is。被試品所需的電流可按其電容估算，Is=Us w Cx，其中Cx包括試品電容和附加電容（F）。（3）容量。根據(jù)試驗變壓器輸出的額定電流及額定電壓，便可確定試驗變壓器的容量，即P=UnIn。根據(jù)部頒標準規(guī)定，我國試驗變壓器的電壓等級有：5、10、25、35、50、100、150、300kV等；容量等級有：3、5、10、25、50、100、150、200kVA等。由計算結(jié)果，查部頒標準即可選出所需要的試驗變壓器。如有特殊要求，一般可向制造廠商訂購特殊規(guī)格的試驗變壓器。</p><p style="text-indent:25px">變壓器的日常巡檢： 1) 變壓器的油溫和溫度計應正常，儲油柜的油位應與溫度相對應，各部位無滲油、漏油。 2) 套管油位應正常。套管外部無破損裂紋、無嚴重油污、無放電痕跡及其他異?，F(xiàn)象。 3) 變壓器聲音正常。 4) 各冷卻器手感溫度應相近、風扇、油泵運轉(zhuǎn)正常。油流繼電器工作正常。 5) 吸濕器完好、吸附劑干燥。 6) 引線接頭、電纜、母線應無發(fā)熱跡象。 7) 壓力釋放閥或安全氣道及防爆膜應完好無損。 8) 氣體繼電器內(nèi)應無氣體。 9) 個控制箱和二次端子箱應關(guān)嚴，無受潮。變壓器的主要部件是一個鐵心和套在鐵心上的兩個繞組。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">在直流電阻測試完成后,變壓器有時會有剩磁,造成不能立即運行的情況出現(xiàn),在測試完成后，將測試線正負極顛倒,進行一下反向充電,可有效避免上述情況出現(xiàn)。具體時間根據(jù)變壓器容量不同，以及測試電流的大小,靈活掌握。有載調(diào)壓的變壓器測量高壓側(cè)電阻時從1或17zui大電阻檔開始測量。為節(jié)約時間，測試過程中可按復位鍵，不必等待放電過程結(jié)束,便可直接再次氣動測量。量程范圍內(nèi)盡量選用大電流以增強穩(wěn)定性能，同時也應考慮試品電流的承受能力。安微變壓器綜合試驗臺</p><p
