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?。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/，安徽供應(yīng)高頻電子變壓器，安徽供應(yīng)高頻電子變壓器，安徽供應(yīng)高頻電子變壓器，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)。變壓器平時(shí)的維護(hù)和保養(yǎng)也是很重要的環(huán)節(jié)。安徽供應(yīng)高頻電子變壓器</p><div
