LearnEngineering制作的動畫，視頻中我們可以很直觀的學習變壓器的工作原理，變壓器是利用電磁感應的原理來改變交流電壓的裝置，主要構件是初級線圈、次級線圈和鐵芯（磁芯）。主要功能有：電壓變換、電流變換、阻抗變換、隔離、穩(wěn)壓（磁飽和變壓器）等。變壓器由鐵芯（或磁芯）和線圈組成，線圈有兩個或兩個以上的繞組，貴州電子變壓器測試系統(tǒng)，其中接電源的繞組叫初級線圈，其余的繞組叫次級線圈，貴州電子變壓器測試系統(tǒng)。首先選擇變壓器的額定電壓。高壓側電壓與所接入電網(wǎng)電壓相等，低壓側電壓比低壓側電網(wǎng)的電壓高10%或5%（取決變壓器電壓等級和阻抗電壓大?。活~定容量選擇。計算變壓器所帶負荷的大?。ㄒ蠼y(tǒng)計比較大綜合負荷，將有功負荷kW值換算成視在功率kVA），如果是兩臺變壓器，那么每臺變壓器的容量可按照比較大綜合負荷的70%選擇，一臺變壓器要按總負荷考慮，并留有適當?shù)脑６?。其它明星參?shù)可結合變壓器產(chǎn)品適當考慮。例如：選擇35/10kV變壓器。假定比較大負荷為3500kW，功率因數(shù)為，選兩臺變壓器，容量S=×3500/，可選擇3150kVA的變壓器，貴州電子變壓器測試系統(tǒng)，電壓比為35kV/。再從產(chǎn)品目錄中選擇型號。對于零部件松動、接觸不良甚至存在放電現(xiàn)象，應及時斷開變壓器跌落保險，消除隱患。貴州電子變壓器測試系統(tǒng)</p><div

在鐵芯中產(chǎn)生的交變磁通不僅穿過原繞組，同時也穿過副繞組，它分別在兩個繞組中引起感應電動勢。這時如果開關K合上，副繞組與外電路的負載相連通，便有電流I2流出，負載端電壓即為U2，于是輸出電能。對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應該如何調(diào)整？運行中系統(tǒng)電壓過高或過低，影響設備的正常運行時，需要對變壓器分接開關進行適當?shù)卣{(diào)整，以保持變壓器二次側電壓的正常。10kV變壓器的分接開關有三個位置，調(diào)壓范圍為±5%，當系統(tǒng)的電壓變化不超過額定電壓的±5%時，可以通過調(diào)節(jié)變壓器分接開關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，分接開關有三擋，即Ⅰ擋時，為10500/400V；Ⅱ擋時，為10000/400V；Ⅲ擋時，為9500/400V。當系統(tǒng)電壓高，超過額定電壓時，變壓器二次側母線電壓高，需要將變壓器分接開關調(diào)到Ⅰ擋位置。如果系統(tǒng)電壓低，達不到額定電壓時，變壓器二次側電壓低，就需要將變壓器分接開關調(diào)至Ⅲ擋位置。即所謂的“高往高處調(diào)，低往低處調(diào)”。但是，變壓器分接開關的調(diào)整要注意相對地穩(wěn)定，不可頻繁調(diào)整，否則將影響變壓器的運行壽命。貴州電子變壓器測試系統(tǒng)一般在住宅樓中大家可能覺得變壓器好像不是很常見，但其實它可能都是隱藏在電箱背后的，只不過大家看不見。</p><div

src="https://tyunfile.71360.com/UploadFile/ZRX888/637284368063710938/7461720.png"></div><p> 1、變壓器定義、作用 </p> <p> 變壓器是一種相對靜止的電氣設備，由繞在同一個鐵心上的兩個或兩個以上的繞組組成的，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（一次）線圈和次級（二次）線圈共同繞在一個鐵芯上，當一次線圈通入電壓U1后，在鐵芯中產(chǎn)生交變磁通，這個磁通穿過一次繞組和二次繞組，根據(jù)電磁感應定律，在一次繞組和二次繞組中分別產(chǎn)生感應電勢E1和E2。根據(jù)電磁感應定律可知，一次側、二次側繞組的感應電勢分別為：E1/E2=U1/U2=N1/N2=K(k為變比) </p> <p> <br /> </p><p style="text-indent:25px">對于Ⅰ類和Ⅱ類的單相變壓器，試驗次數(shù)為三次；如無另行規(guī)定，帶有分接的變壓器的試驗應分別在zui大、額定和zui小分接位置上各進行一次；三相變壓器試驗次數(shù)為九次，在不同分接位置上進行，即在旁柱的zui大分接、中柱的額定分接和另一旁柱的zui小分接位置上分別進行三次。對于Ⅲ類變壓器，其試驗程序和分接位置通常由制造單位和用戶協(xié)商確定，一般與Ⅰ類和Ⅱ類變壓器相同。每次試驗除用示波器記錄電流波形外，還應派專人監(jiān)視試品；每次試驗過后，應對電流波形、氣體繼電器進行觀察，并測量該分接的電抗值。短路試驗后應重復全部例行試驗，包括在100.0%規(guī)定試驗電壓下的絕緣試驗；如果規(guī)定了雷電沖擊試驗，也應在此階段中進行；低對于Ⅰ類變壓器，除絕緣試驗外的其他試驗項目，可以不做。變壓器發(fā)生不同性質(zhì)的故障，聲音會發(fā)生變化。這時應根據(jù)現(xiàn)場情采取措施，查找故障原因。</p><div
