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?。?；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

(2)避雷器的接地線應(yīng)與變壓器低壓繞組中性點(diǎn)及變壓器金屬外殼連接在一起共同接地，亦稱作“三位一體”的接地方式。這種接法的目的是保證當(dāng)變壓器高壓側(cè)受雷擊引起避雷器放電時(shí)，變壓器主絕緣所承受的電壓*是避雷器的殘壓，而接地裝置上的電壓并不作用在變壓器主絕緣上，使避雷器與變壓器得到較好的絕緣配合，能減少高、低壓繞組間和高壓繞組對(duì)變壓器外殼之間發(fā)生絕緣擊穿的危險(xiǎn)。 (3)對(duì)于低壓，架空線路引出3~10kV，Y，yn0配電變壓器，為防止低壓側(cè)落雷造成絕緣擊穿事故，要求在配電變壓器低壓出線上安裝一組低壓避雷器，這樣不*可保護(hù)變壓器的低壓繞組，同時(shí)還能保護(hù)當(dāng)雷電波從低壓繞組折換到高壓繞組時(shí)，不致使高壓繞組絕緣損壞。肇慶實(shí)驗(yàn)變壓器</p><p
