變壓器據(jù)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(diào)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(lián)電抗器、變壓器等）。電磁灶是一種運用電流的磁效應(yīng)加溫基本原理生產(chǎn)制造的電炊具。它由高頻率電磁感應(yīng)加熱電磁線圈（即勵磁線圈）、高頻率輸出功率變換設(shè)備、控制板和磁鐵原材料底鍋構(gòu)成。加熱爐和電磁灶內(nèi)的加溫電磁線圈板構(gòu)成高頻率變壓器。內(nèi)部電磁線圈是變壓器的關(guān)鍵一部分，主次一部分是加熱爐。當(dāng)內(nèi)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(yīng)電動勢，根據(jù)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(fù)載）。變壓器歸類。原理：變壓器是一種轉(zhuǎn)換交流電流、交流電路和特性阻抗的設(shè)備。當(dāng)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(jìn)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(gòu)成。電磁線圈有兩個或2個之上的繞阻，在其中聯(lián)接到開關(guān)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。 </p> <p> </p><p style="text-indent:25px">單相短路測試：單相短路測試項目通常用來測試單相變壓器的短路損耗和阻抗電壓。另外，在測試三相變壓器時，沒有三相電源或電源容量較小時，及在制造過程或運行中需逐相檢查以確定故障相時，也需要用單相短路試驗方法；按照圖的方法接線：用一單相電源作為測試電源，火線接到測試儀的A相電流端子正端，黃鉗子粗線接到A相電流端子的負(fù)端，細(xì)線接到A相電壓端子Ua，紅鉗子粗線直接接到測試電源的零線，細(xì)線接到B相電壓端子Ub，兩把鉗子分別夾到低壓側(cè)兩個接線柱上。高壓側(cè)用專門短接線短接，注意一定要短接良好，否則會影響測試數(shù)據(jù)。變壓器常用的鐵芯形狀一般有E 型和C型鐵芯，XED型，ED型。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="成都測量變壓器,變壓器"
