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">對(duì)于變壓器絕緣在線檢測(cè)zui有效的方法之一是監(jiān)測(cè)局部放電電脈沖參量。變壓器正常運(yùn)行中局部放電量較小,近年生產(chǎn)的110kV以上變壓器局部放電量都控制在500pC以下;但在實(shí)際運(yùn)行中,即使出現(xiàn)有5000pC左右的放電也照常運(yùn)行,其絕緣缺陷發(fā)展過(guò)程可能延續(xù)幾周甚至幾年。在線測(cè)量時(shí),由于受現(xiàn)場(chǎng)干擾信號(hào)的影響,直接測(cè)量局部放電高頻參量較為困難,且對(duì)運(yùn)行設(shè)備在進(jìn)行在線監(jiān)測(cè)采集所需信號(hào)時(shí)應(yīng)盡量不改變?cè)O(shè)備的運(yùn)行接線狀態(tài)。因此,將信號(hào)取樣點(diǎn)選擇在變壓器鐵芯接地引出線和中性點(diǎn)引出線以及高壓套管末屏引出線處,是非常有效及合理的。在任何情況下它不會(huì)影響變壓器的正常運(yùn)行。但傳感器選在鐵芯接地點(diǎn)時(shí),對(duì)傳感器和放大器的靈敏度要求比選在套管末屏取樣要求更高。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。</p><div

變壓器是應(yīng)用，常見(jiàn)的電力設(shè)備之一。我們都知道變壓器是一種能將某一種電壓、電流、相數(shù)的交流電能轉(zhuǎn)變成另一種電壓、電流、相數(shù)的交流電能的電器。在生產(chǎn)和生活中，經(jīng)常會(huì)用到各種高低不同的電壓，比如工廠中常用的三相異步電動(dòng)機(jī)的額定電壓是380V或220V；照明電路中要用220V；機(jī)床照明、行燈等只需要36V、24V，甚至更低的電壓。這就需要使用變壓器把同一交流電壓變換成頻率相同的不同等級(jí)的電壓，來(lái)滿足不同的使用要求。變壓器不僅能用于改變電壓，還可以用來(lái)改變電流（如變流器、大電流發(fā)生器等）、改變相位（如改變線圈的連接方法來(lái)改變變壓器的極性或組別）、變換阻抗（電子線路中的輸入、輸出變壓器）等。單相變壓器工作原理變壓器的基本工作原理是電磁感應(yīng)原理。上圖所示為一個(gè)簡(jiǎn)單的單相變壓器，其基本結(jié)構(gòu)是在閉合的鐵芯上繞有兩個(gè)匝數(shù)不等的繞組（又稱線圈），繞組之間、鐵芯和繞組之間均相互絕緣，鐵芯由硅鋼片疊成?，F(xiàn)將匝數(shù)為W1的繞組與電源相連，稱該繞組為原繞組或初級(jí)繞組，匝數(shù)為W2的繞組通過(guò)開(kāi)關(guān)K與負(fù)載相連，稱為副繞組或次級(jí)繞組。當(dāng)接通電源，把交流電壓U1加到原繞組上后，交流電流l1流入該繞組，然后產(chǎn)生勵(lì)磁作用。東莞變壓器負(fù)載測(cè)試</p><p
