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(lái)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(jí)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(duì)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(hào)圖3-45所示是行輸出變壓器電路符號(hào)。其中，圖3-45(a)所示為分立式行輸出變壓器的電路符號(hào)，圖3-45(b)所示是一體化行輸出變壓器的電路符號(hào)。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。變壓器可將一種電壓的交流電能變換為同頻率的另一種電壓的交流電能。東莞電子變壓器參數(shù)測(cè)試</p><p
