變壓器是一種相對靜止的電氣設(shè)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(yīng)定律，在一次繞組和二次繞組中分別產(chǎn)生感應(yīng)電勢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)電勢分別為：E1/E2=U1/U2=N1/N2=K(k為變比)

style="text-indent:25px">電壓比測量是驗證變壓器能否達到預(yù)期的電壓變換效果。絕緣裝配后的電壓比試驗是檢驗繞組的匝數(shù)與繞向是否正確；引線裝配后的電壓比試驗時間檢查分接開關(guān)與繞組的聯(lián)結(jié)組標號是否正確；總裝后的電壓比試驗是檢査變壓器分接開關(guān)內(nèi)部所處位置與外部指示位置是否一致及線端標志是否正確。對于有并聯(lián)支路的繞組，如果在電壓比試驗中可以明顯的發(fā)現(xiàn)一匝的誤差時，應(yīng)分別對每個支路進行電壓比測量；否則應(yīng)進行電勢差試驗，以確保并聯(lián)支路的匝數(shù)相等，在此前提下方能進行電壓比測量。</p><p style="text-indent:25px">變壓器在安裝的時候需要注意以下事項： 1.應(yīng)當安裝在供電范圍的負荷中心，一般都是比較靠近大的負荷。 2.安裝位置必須安全可靠，運輸方便，便于吊裝檢修，符合城鎮(zhèn)規(guī)劃。這點是相對比較重要的。 3.對于安在變壓器桿上的，應(yīng)保證足夠堅固，臺面距地應(yīng)有3米高，應(yīng)有警示標志，接地線應(yīng)有護套，不得裝于大的轉(zhuǎn)角桿、分支桿；不易巡視吊裝的電桿；架空線、接戶線過多的電桿。一定要保證用電的安全以及人員安全，避免造成不必要的事故。 4.按說3米還是滿足安全距離的。應(yīng)該讓開窗戶，以不影響采光、通風、觀景，以人為本嘛，環(huán)境的舒適敞亮。變壓器的檢測中涉及到很多專業(yè)的項目以及參數(shù)，這個時候一定要尋求專業(yè)人士進行解答。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">大部分運作中的繁雜變壓器通常超出這一使用壽命。在具體應(yīng)用中，依據(jù)運作狀況，按制造行業(yè)要求提早取代。比如，國家公布文檔，規(guī)定取代1976年上下生產(chǎn)制造的一批鋁電磁線圈薄絕緣層變壓器。交流電流。變壓器關(guān)鍵分成1類。依據(jù)相數(shù)：1）單相電變壓器：用以單相電負載和三相變壓器組。2）三相變壓器：用以三相系統(tǒng)軟件的工作電壓升降機。變壓器是啥。2、依據(jù)制冷方法：1）干試變壓器：當然制冷或提升離心風機熱對流制冷，關(guān)鍵用以多層建筑、高速收費站、部分照明燈具、電子電路等小容積變壓器。2）油浸式變壓器：以油為制冷物質(zhì)，如油浸過溫保護、油變風冷式、油浸泡制冷、強制性油循環(huán)系統(tǒng)等。按主要用途：1）電力工程變壓器：用以輸變電系統(tǒng)軟件的工作電壓升降機。2）電壓互感器：如互感器、電壓互感器、檢測儀表、繼電保護裝置設(shè)備等。3）實驗變壓器：能造成高壓，對電器設(shè)備開展高壓實驗。變壓器的功能主要有：電壓變換；電流變換，阻抗變換；隔離；穩(wěn)壓（磁飽和變壓器）等。佛山變壓器需要那些檢測</p><p style="text-indent:25px">變壓器在出廠之后都會接受檢測，并且在使用期間也會定期對它進行檢測。惠州變壓器特性測試臺</p><p
