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。

連接并聯(lián)支路的一端，測量各同名端的電勢差，其電勢差應(yīng)等于零；為了避免由于回路接觸不良造成電勢差為零，允許在測量中加入一匝，使電勢差為1V；臨時匝應(yīng)分別正繞與反繞串入回路，其電勢差均應(yīng)近似等于1V； (3) 為了避免因增加串聯(lián)匝數(shù)而使電勢差減小的現(xiàn)象，測量電勢差的電壓表應(yīng)盡量采用高內(nèi)阻的電壓表； (4) 電勢差試驗時被試?yán)@組的電壓雖然只有1V，但其電位往往很高；在并聯(lián)支路中如有串聯(lián)線段，試驗中可將其打開，分別測量幾個并聯(lián)支路的電勢差，以降低被試?yán)@組的電位； (5) 測量儀表的一端應(yīng)可靠接地，儀表的量程開始應(yīng)置于zui大位罝，送電指示正常后，再逐級縮小量程，以避免損壞儀表。</p><p
