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(yàn)變壓器輸出的額定電流及額定電壓，便可確定試驗(yàn)變壓器的容量，即P=UnIn。根據(jù)部頒標(biāo)準(zhǔn)規(guī)定，我國(guó)試驗(yàn)變壓器的電壓等級(jí)有：5、10、25、35、50、100、150、300kV等；容量等級(jí)有：3、5、10、25、50、100、150、200kVA等。由計(jì)算結(jié)果，查部頒標(biāo)準(zhǔn)即可選出所需要的試驗(yàn)變壓器。如有特殊要求，一般可向制造廠商訂購(gòu)特殊規(guī)格的試驗(yàn)變壓器。四川實(shí)驗(yàn)變壓器及時(shí)消除故障和補(bǔ)充油，確保油位保持在油標(biāo)1/4-3/4處對(duì)于變壓器保持穩(wěn)定是非常有必要的。</p><div

變壓器是應(yīng)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(huì)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(dòng)機(jī)的額定電壓是380V或220V；照明電路中要用220V；機(jī)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(jí)的電壓，來(lái)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(lái)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(lái)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(yīng)原理。上圖所示為一個(gè)簡(jiǎn)單的單相變壓器，其基本結(jié)構(gòu)是在閉合的鐵芯上繞有兩個(gè)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(jí)繞組，匝數(shù)為W2的繞組通過開關(guān)K與負(fù)載相連，稱為副繞組或次級(jí)繞組。當(dāng)接通電源，把交流電壓U1加到原繞組上后，交流電流l1流入該繞組，然后產(chǎn)生勵(lì)磁作用。在檢測(cè)變壓器的時(shí)候一定要遵守操作規(guī)范進(jìn)行。</p><div

LearnEngineering制作的動(dòng)畫，視頻中我們可以很直觀的學(xué)習(xí)變壓器的工作原理，變壓器是利用電磁感應(yīng)的原理來(lái)改變交流電壓的裝置，主要構(gòu)件是初級(jí)線圈、次級(jí)線圈和鐵芯（磁芯）。主要功能有：電壓變換、電流變換、阻抗變換、隔離、穩(wěn)壓（磁飽和變壓器）等。變壓器由鐵芯（或磁芯）和線圈組成，線圈有兩個(gè)或兩個(gè)以上的繞組，其中接電源的繞組叫初級(jí)線圈，其余的繞組叫次級(jí)線圈。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(jí)和阻抗電壓大?。?；額定容量選擇。計(jì)算變壓器所帶負(fù)荷的大?。ㄒ蠼y(tǒng)計(jì)比較大綜合負(fù)荷，將有功負(fù)荷kW值換算成視在功率kVA），如果是兩臺(tái)變壓器，那么每臺(tái)變壓器的容量可按照比較大綜合負(fù)荷的70%選擇，一臺(tái)變壓器要按總負(fù)荷考慮，并留有適當(dāng)?shù)脑６取Ｆ渌餍菂?shù)可結(jié)合變壓器產(chǎn)品適當(dāng)考慮。例如：選擇35/10kV變壓器。假定比較大負(fù)荷為3500kW，功率因數(shù)為，選兩臺(tái)變壓器，容量S=×3500/，可選擇3150kVA的變壓器，電壓比為35kV/。再?gòu)漠a(chǎn)品目錄中選擇型號(hào)。變壓器發(fā)生不同性質(zhì)的故障，聲音會(huì)發(fā)生變化。這時(shí)應(yīng)根據(jù)現(xiàn)場(chǎng)情采取措施，查找故障原因。湖南供應(yīng)高頻電子變壓器</p><p
