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），如果是兩臺變壓器，那么每臺變壓器的容量可按照比較大綜合負(fù)荷的70%選擇，一臺變壓器要按總負(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。變壓器的檢測中涉及到很多專業(yè)的項(xiàng)目以及參數(shù)，這個(gè)時(shí)候一定要尋求專業(yè)人士進(jìn)行解答。江門變壓器綜合參數(shù)測試系統(tǒng)</p><p

行輸出變壓器又稱逆程變壓器、回掃變壓器，俗稱行輸出，它是電視機(jī)、顯示器中的一個(gè)重要變壓器。1.行輸出變壓器結(jié)構(gòu)行輸出變壓器的全部繞組和高壓整流管均密封在其中，底部引出各個(gè)繞組的引腳，高壓輸出采用高壓引線直接送至顯像管的高壓嘴。有的行輸出變壓器上只有一個(gè)電壓調(diào)節(jié)旋鈕，那是用來調(diào)節(jié)顯像管聚焦極電壓的。記憶行輸出變壓器兩個(gè)旋鈕位置的方法參考如圖3-44所示的兩個(gè)電壓調(diào)節(jié)電路。圖3-44兩個(gè)電壓調(diào)節(jié)電路重要提示一體化行輸出變壓器體積小，重量輕，省去了硅柱，工作穩(wěn)定性好。內(nèi)部的高壓整流二極管將各級繞組隔離，減小了分布電容，能獲得優(yōu)良的高壓負(fù)載特性。但是，由于行輸出變壓器工作在高壓、高頻狀態(tài)下，故障發(fā)生率相對電視機(jī)中其他元器件而言比較高，而且大多數(shù)情況下是高壓繞組部分損壞。由于一體化行輸出變壓器采用環(huán)氧樹脂等材料封裝，所以更換時(shí)得整個(gè)行輸出變壓器一起更換，增加了維修成本。2.行輸出變壓器電路符號圖3-45所示是行輸出變壓器電路符號。其中，圖3-45(a)所示為分立式行輸出變壓器的電路符號，圖3-45(b)所示是一體化行輸出變壓器的電路符號。用虛線框表示兩組繞組組合成一體，并在內(nèi)部設(shè)有高壓整流管。遼寧實(shí)驗(yàn)變壓器</p><p
