4、短路阻抗是在額定頻率和參考溫度下，一對(duì)繞組中某一繞組端子之間的等效串聯(lián)阻抗；其百分?jǐn)?shù)等于短路電壓與額定電壓之比，測(cè)量時(shí)應(yīng)以三相電流的算術(shù)平均值為準(zhǔn)。安徽變壓器檢測(cè)儀變壓器綜合測(cè)試儀一般在使用前一定要經(jīng)過(guò)嚴(yán)格的培訓(xùn)。</p><div

LearnEngineering制作的動(dòng)畫(huà)，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)和阻抗電壓大小）；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?。其它明星參?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)。 </p><p style="text-indent:25px">我們選擇試驗(yàn)變壓器時(shí)，主要考慮以下幾點(diǎn)：（1）電壓。依據(jù)試品的要求，首先選用具有合適電壓的試驗(yàn)變壓器，使試驗(yàn)變壓器的高壓側(cè)額定電壓Un高于被試品的試驗(yàn)電壓Us,即Un>Us。其次應(yīng)檢查試驗(yàn)變壓器所需的低壓側(cè)電壓，是否能和現(xiàn)場(chǎng)電源電壓，調(diào)壓器相匹配。（2）電流。試驗(yàn)變壓器的額定輸出電流In應(yīng)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(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。變壓器在使用期間一定要聯(lián)系專業(yè)的檢測(cè)人員進(jìn)行檢測(cè)。</p><div
