變壓器據主要用途，可分成電力工程變壓器和**型變壓器（爐壁變壓器、整流器變壓器、直流實驗變壓器等），電壓調節(jié)器、礦用防變壓器、聲頻變壓器、高頻變壓器、高頻率變壓器、沖擊性變壓器、儀表盤變壓器、電子器件變壓器、串聯電抗器、變壓器等）。電磁灶是一種運用電流的磁效應加溫基本原理生產制造的電炊具。它由高頻率電磁感應加熱電磁線圈（即勵磁線圈）、高頻率輸出功率變換設備、控制板和磁鐵原材料底鍋構成。加熱爐和電磁灶內的加溫電磁線圈板構成高頻率變壓器。內部電磁線圈是變壓器的關鍵一部分，主次一部分是加熱爐。當內部一次加溫電磁線圈板有交流電流輸出時，必定會在二次爐墻上造成感應電動勢，根據爐墻自身的電阻器造成發(fā)熱量（因此加熱爐自身也是一個負載）。變壓器歸類。原理：變壓器是一種轉換交流電流、交流電路和特性阻抗的設備。當一次電磁線圈中有交流電路時，鐵芯（或鐵芯）會造成溝通交流磁通量，進而在二次電磁線圈中造成工作電壓（或電流量）。變壓器由變壓器鐵芯（或變壓器骨架）和電磁線圈構成。電磁線圈有兩個或2個之上的繞阻，在其中聯接到開關電源的繞阻稱之為一次電磁線圈，其他的稱之為二次電磁線圈。變壓器歸類：電容器。

空載實驗目的:通過測量空載電流和一、二次電壓及空載功率來計算變比、空載電流百分數、鐵損和勵磁阻抗。 </p> <p> 1.低壓側加電壓,高壓側開路，為了便于測量和安全,空載實驗一般在低壓繞組上加電壓,高壓繞組開路。 </p> <p> 2.空載電流和空載功率必須是額定電壓時的值，并以此求取勵磁參數； </p> <p> 3.若要的達到高壓側參數須折算。 </p> <p> <br /> </p><p> 變壓器容量計算首先選擇變壓器的額定電壓。高壓側電壓與所接入電網電壓相等，低壓側電壓比低壓側電網的電壓高10%或5%（取決變壓器電壓等級和阻抗電壓大小）；額定容量選擇。計算變壓器所帶負荷的大?。ㄒ蠼y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，并留有適當的裕度。其它明星參數可結合變壓器產品適當考慮。例如：選擇35/10kV變壓器。假定比較大負荷為3500kW，功率因數為，選兩臺變壓器，容量S=×3500/，可選擇3150kVA的變壓器，電壓比為35kV/。再從產品目錄中選擇型號。一、變壓器容量計算公式：1、計算負載的每相比較大功率將A相、B相、C相每相負載功率**相加，如A相負載總功率10KW，B相負載總功率9KW，C相負載總功率11KW，取比較大值11KW。(注：單相每臺設備的功率按照銘牌上面的比較大值計算，三相設備功率除以3，等于這臺設備的每相功率。)例如：C相負載總功率=電腦300W×10臺)+(空調2KW×4臺)=11KW2、計算三相總功率11KW×3相=33KW(變壓器三相總功率)3、計算變壓器總功率三相總功率/，這是重要的步驟。變壓器發(fā)生不同性質的故障，聲音會發(fā)生變化。這時應根據現場情采取措施，查找故障原因。</p><div

style="text-indent:25px">變壓器設計制造完成后，其線圈和內部結構就確定下來，因此對一臺多繞組的變壓器線圈而言，如果電壓等級相同、繞制方法相同，則每個線圈對應參數(Ci、Li)就應該是確定的。因此每個線圈的頻域特征響應也隨之確定，對應的三相線圈之間其頻率圖譜具有一定可比性。變壓器在試驗過程中發(fā)生匝間、相間短路，或在運輸過程中發(fā)生沖撞，造成線圈相對位移，以及運行過程中在短路和故障狀態(tài)下因電磁拉力造成線圈變形，就會使變壓器繞組的分布參數發(fā)生變化。進而影響并改變變壓器原有的頻域特征，即頻率響應發(fā)生幅度變化和諧振頻點偏移等。變壓器必須檢查套管的油位是否在正常范圍之內。江蘇電子變壓器高壓測試</p><p
