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。檢查分接開關(guān)的位置是否正確。</p><div
