變壓器是一種相對(duì)靜止的電氣設(shè)備，由繞在同一個(gè)鐵心上的兩個(gè)或兩個(gè)以上的繞組組成的，繞組之間通過交變的磁通的相互聯(lián)系。為了把發(fā)電廠發(fā)出的電能經(jīng)濟(jì)的傳輸、合理的分配以及安全的使用，都要用到電力變壓器。 </p> <p> 2、變壓器工作原理 </p> <p> 簡單說變壓器的工作原理就是“電生磁，磁生電”。變壓器的初級(jí)（一次）線圈和次級(jí)（二次）線圈共同繞在一個(gè)鐵芯上，當(dāng)一次線圈通入電壓U1后，在鐵芯中產(chǎn)生交變磁通，這個(gè)磁通穿過一次繞組和二次繞組，根據(jù)電磁感應(yīng)定律，在一次繞組和二次繞組中分別產(chǎn)生感應(yīng)電勢(shì)E1和E2。根據(jù)電磁感應(yīng)定律可知，一次側(cè)、二次側(cè)繞組的感應(yīng)電勢(shì)分別為：E1/E2=U1/U2=N1/N2=K(k為變比)

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(gè)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(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(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

在鐵芯中產(chǎn)生的交變磁通不僅穿過原繞組，同時(shí)也穿過副繞組，它分別在兩個(gè)繞組中引起感應(yīng)電動(dòng)勢(shì)。這時(shí)如果開關(guān)K合上，副繞組與外電路的負(fù)載相連通，便有電流I2流出，負(fù)載端電壓即為U2，于是輸出電能。對(duì)變壓器的作用和工作原理有了一定的了解后，我們來討論一下變壓器分接開關(guān)應(yīng)該如何調(diào)整？運(yùn)行中系統(tǒng)電壓過高或過低，影響設(shè)備的正常運(yùn)行時(shí)，需要對(duì)變壓器分接開關(guān)進(jìn)行適當(dāng)?shù)卣{(diào)整，以保持變壓器二次側(cè)電壓的正常。10kV變壓器的分接開關(guān)有三個(gè)位置，調(diào)壓范圍為±5%，當(dāng)系統(tǒng)的電壓變化不超過額定電壓的±5%時(shí)，可以通過調(diào)節(jié)變壓器分接開關(guān)的位置來解決電壓過高或過低的問題。無載調(diào)壓的配電變壓器，分接開關(guān)有三擋，即Ⅰ擋時(shí)，為10500/400V；Ⅱ擋時(shí)，為10000/400V；Ⅲ擋時(shí)，為9500/400V。當(dāng)系統(tǒng)電壓高，超過額定電壓時(shí)，變壓器二次側(cè)母線電壓高，需要將變壓器分接開關(guān)調(diào)到Ⅰ擋位置。如果系統(tǒng)電壓低，達(dá)不到額定電壓時(shí)，變壓器二次側(cè)電壓低，就需要將變壓器分接開關(guān)調(diào)至Ⅲ擋位置。即所謂的“高往高處調(diào)，低往低處調(diào)”。但是，變壓器分接開關(guān)的調(diào)整要注意相對(duì)地穩(wěn)定，不可頻繁調(diào)整，否則將影響變壓器的運(yùn)行壽命。變壓器特性測(cè)試儀（又稱變壓器容量測(cè)試儀）是一款全自動(dòng)的CT和PT特性測(cè)試儀。上海高頻變壓器的測(cè)試</p><p
