style="text-indent:25px">當(dāng)變壓器的初級繞組通電后，線圈所產(chǎn)生的磁通在鐵心流動，因為鐵心本身也是導(dǎo)體，在垂直于磁力線的平面上就會感應(yīng)電勢，這個電勢在鐵心的斷面上形成閉合回路并產(chǎn)生電流，好象一個旋渦所以稱為“渦流”。這個“渦流”使變壓器的損耗增加，并且使變壓器的鐵心發(fā)熱變壓器的溫升增加。由“渦流”所產(chǎn)生的損耗我們稱為“鐵損”。另外要繞制變壓器需要用大量的銅線，這些銅導(dǎo)線存在著電阻，電流流過時這電阻會消耗一定的功率，這部分損耗往往變成熱量而消耗，廣州安全電壓變壓器，我們稱這種損耗為“銅損”，廣州安全電壓變壓器，廣州安全電壓變壓器。所以變壓器的溫升主要由鐵損和銅損產(chǎn)生的。變壓器在我們的日常生活中運用的很多，比如說有些地方電壓不穩(wěn)定那么這個時候就需要用變壓器了。廣州安全電壓變壓器</p><div

從行輸出變壓器的電路符號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，電視機顯像管所需要的高壓、中壓和其他電路需要的低壓要通過行輸出高壓電路來獲得。中、高壓是利用行掃描逆程期間產(chǎn)生的半個周期諧振電壓，通過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，降低整機功耗。行輸出級消耗的能量約占整機功耗的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，行逆程脈沖消失，可起保護(hù)作用。(5)通過行輸出變壓器可以獲得上萬伏的顯像管陽極高壓，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。通過多組二次升壓繞組、整流電路，可得到多種電壓等級的低、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。惠州變壓器檢測儀器在變壓器的日常檢查中還要著重關(guān)注吸濕器的檢查。</p><div
