從行輸出變壓器的電路符號(hào)中可以看出一次和二次以及繞組的結(jié)構(gòu)。圖3-45行輸出變壓器電路符號(hào)行輸出變壓器是組成行輸出高壓電路的重要元器件，電視機(jī)顯像管所需要的高壓、中壓和其他電路需要的低壓要通過(guò)行輸出高壓電路來(lái)獲得。中、高壓是利用行掃描逆程期間產(chǎn)生的半個(gè)周期諧振電壓，通過(guò)行輸出變壓器的升壓經(jīng)整流后獲得的。重要提示利用行逆程回掃期間的能量來(lái)獲得中、高電壓具有下列一些好處。(1)有利于節(jié)省能量，降低整機(jī)功耗。行輸出級(jí)消耗的能量約占整機(jī)功耗的60%。(2)由于行頻高達(dá)15625Hz，頻率高，有利于濾波，即用較小的濾波電容可獲得很好的濾波性能。(3)行逆程脈沖電壓較高，較容易獲得中、高壓。(4)具有保護(hù)顯像管的作用。當(dāng)行振蕩電路發(fā)生故障時(shí)，行逆程脈沖消失，可起保護(hù)作用。(5)通過(guò)行輸出變壓器可以獲得上萬(wàn)伏的顯像管陽(yáng)極高壓，獲得幾百伏的顯像管加速極電壓和聚焦極電壓，以及其他電路的低電壓。3.行輸出變壓器實(shí)用電路圖3-46所示是行輸出變壓器電路。輸入該變壓器的是行逆程脈沖。通過(guò)多組二次升壓繞組、整流電路，可得到多種電壓等級(jí)的低、中、高直流電壓。從升壓繞組上得到20～25kV高壓，作為顯像管高壓。從升壓繞組抽頭得到直流電壓。</p><p style="text-indent:25px">我們選擇試驗(yàn)變壓器時(shí)，主要考慮以下幾點(diǎn)：（1）電壓。依據(jù)試品的要求，首先選用具有合適電壓的試驗(yàn)變壓器，使試驗(yàn)變壓器的高壓側(cè)額定電壓Un高于被試品的試驗(yàn)電壓Us,即Un>Us。其次應(yīng)檢查試驗(yàn)變壓器所需的低壓側(cè)電壓，是否能和現(xiàn)場(chǎng)電源電壓，調(diào)壓器相匹配。（2）電流。試驗(yàn)變壓器的額定輸出電流In應(yīng)大于被試品所需的電流Is，即In>Is。被試品所需的電流可按其電容估算，Is=Us w Cx，其中Cx包括試品電容和附加電容（F）。（3）容量。根據(jù)試驗(yàn)變壓器輸出的額定電流及額定電壓，便可確定試驗(yàn)變壓器的容量，即P=UnIn。根據(jù)部頒標(biāo)準(zhǔn)規(guī)定，我國(guó)試驗(yàn)變壓器的電壓等級(jí)有：5、10、25、35、50、100、150、300kV等；容量等級(jí)有：3、5、10、25、50、100、150、200kVA等。由計(jì)算結(jié)果，查部頒標(biāo)準(zhǔn)即可選出所需要的試驗(yàn)變壓器。如有特殊要求，一般可向制造廠商訂購(gòu)特殊規(guī)格的試驗(yàn)變壓器。對(duì)于零部件松動(dòng)、接觸不良甚至存在放電現(xiàn)象，應(yīng)及時(shí)斷開變壓器跌落保險(xiǎn)，消除隱患。</p><div
