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、顯示器中的一個重要變壓器。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旋鈕位置的方法參考如圖3-44所示的兩個電壓調(diào)節(jié)電路。圖3-44兩個電壓調(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，所以更換時得整個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。整機由高速單片機控制，自動化程度高，操作簡便。</p><div

style="text-indent:25px">變壓器鐵芯的硅鋼片含硅量越大就越好嗎：未見得，矽鋼片含硅量的大小對變壓器的質(zhì)量影響不是很大，而有取向和無取向則和鐵芯的型號有關(guān)系。其次，即使是同樣型號的鐵芯如果你工藝處理不好，那品質(zhì)差別也是很大的，其差別有時甚至高達百分之四五十。好的鐵芯而同樣的材料其熱處理和線卷繞制工藝十分關(guān)鍵，良好的熱處理只需很小的10mA激磁電流就能達到15000高斯，而不好的熱處理則可能要50mA的激磁電流才能達到相應(yīng)的15000高斯，這二者之間的懸殊差別是很大的。從專業(yè)的角度來判斷鐵芯的好與不好，主要是通過激磁電流、鐵損耗、飽和參數(shù)幾項指標來進行綜合性評價。在檢查變壓器的時候需要注意對套管進行定期檢查。上海變壓器交流耐壓試驗</p><p
