style="text-indent:25px">薄片鋼芯：變壓器通常采用硅鋼材料的鐵芯作為主磁路。這樣可以使線圈中磁場更加集中，變壓器更加緊湊。電力變壓器的鐵芯在設計的時候必須保防止達到磁路飽和，有時需要在磁路中設計一些氣隙減少飽和。實際使用的變壓器鐵芯采用非常薄，電阻較大的硅鋼片疊壓而成。這樣可以減少每層渦流帶來的損耗和產(chǎn)生的熱量。電力變壓器和音頻電路有相似之處。典型分層鐵芯一般為E和I字母的形狀，稱作“EI變壓器”。這種鐵芯的一個問題就是當斷電之后鐵芯中會保持剩磁。當再次加電后，剩磁會造成鐵芯暫時飽和。對于一些容量超過數(shù)百瓦的變壓器會造成的嚴重后果，如果沒有采用限流電路，涌流可造成主熔斷器熔斷。更嚴重的是，對于大型電力變壓器，涌流可造成主繞組變形、損害。湖北變壓器綜合測試系統(tǒng)自帶面板式微型打印機，可漢化打印測量結(jié)果。</p><div

變壓器是應用，常見的電力設備之一。我們都知道變壓器是一種能將某一種電壓、電流、相數(shù)的交流電能轉(zhuǎn)變成另一種電壓、電流、相數(shù)的交流電能的電器。在生產(chǎn)和生活中，經(jīng)常會用到各種高低不同的電壓，比如工廠中常用的三相異步電動機的額定電壓是380V或220V；照明電路中要用220V；機床照明、行燈等只需要36V、24V，甚至更低的電壓。這就需要使用變壓器把同一交流電壓變換成頻率相同的不同等級的電壓，來滿足不同的使用要求。變壓器不僅能用于改變電壓，還可以用來改變電流（如變流器、大電流發(fā)生器等）、改變相位（如改變線圈的連接方法來改變變壓器的極性或組別）、變換阻抗（電子線路中的輸入、輸出變壓器）等。單相變壓器工作原理變壓器的基本工作原理是電磁感應原理。上圖所示為一個簡單的單相變壓器，其基本結(jié)構(gòu)是在閉合的鐵芯上繞有兩個匝數(shù)不等的繞組（又稱線圈），繞組之間、鐵芯和繞組之間均相互絕緣，鐵芯由硅鋼片疊成?，F(xiàn)將匝數(shù)為W1的繞組與電源相連，稱該繞組為原繞組或初級繞組，匝數(shù)為W2的繞組通過開關(guān)K與負載相連，稱為副繞組或次級繞組。當接通電源，把交流電壓U1加到原繞組上后，交流電流l1流入該繞組，然后產(chǎn)生勵磁作用。</p><p style="text-indent:25px">變壓器變比測試儀常見故障：變比測試的目的及意義：（1）檢查變比是否與銘牌相符，以保證對電壓的正確變換。（2）檢查分接開關(guān)的位置是否正確。（3）在變壓器發(fā)生故障后，通過測量變比來檢查繞組匝間是否存在匝間短路，開路（交接和大修）。（4）測出三相變壓器本身變比的不平衡程度，確定零序分量的大小。（5）準確獲得變比，判斷變壓器是否可以并聯(lián)運行。當兩臺并列運行的變壓器二次側(cè)空載電壓相差為額定電壓的1%時，兩臺變壓器繞組中環(huán)流將達到額定電流的10%左右時，會增加變壓器的損耗，占據(jù)變壓器的容量。因此變比的差值應限制在一定范圍之內(nèi)目前常見的變比測試儀（需要輸入一些銘牌上的數(shù)據(jù)，一般輸入額定電壓，額定分接比，檔位數(shù)），一般電源需要供給220V市電。較新的智能變比測試儀器（盲測無需輸入任何參數(shù)即可測試），采用新的單片機，內(nèi)部有鋰電池供電，支持數(shù)據(jù)存儲及U盤轉(zhuǎn)存，實現(xiàn)打印等微機處理。存放保管儀器時，應注意環(huán)境溫度和濕度。</p><div

style="text-indent:25px">變壓器直流電阻測試儀的測量方法：測量直流電阻是變壓器試驗中的一個重要項目。通過測量，可以檢查出設備的導電回路有無接觸不良、焊接不良、線圈故障及接線錯誤等缺陷。在中、小型變壓器的實際測量中，大多采用直流電橋法，當被試線圈的電阻值在1歐以上的一般用單臂電橋測量，1歐以下的則用雙臂電橋測量。在使用雙臂電橋接線時，電橋的電位樁頭要靠近被測電阻，電流樁頭要接在電位樁頭的上面。測量前，應先估計被測線圈的電阻值，將電橋倍率選鈕置于適當位置，將非被測線圈短路并接地，然后打開電源開關(guān)充電，待充足電后按下檢流計開關(guān)，迅速調(diào)節(jié)測量臂，使檢流計指針向檢流計刻度中間的零位線方向移動，進行微調(diào)，待指針平穩(wěn)停在零位上時記錄電阻值，此時，被測線圈電阻值＝倍率數(shù)×測量臂電阻值。測量完畢，先開放檢流計按鈕，再放開電源開關(guān)。采用高頻開關(guān)電源技術(shù)，輸出電流大，適合大中型變壓器直流電阻測量。中山電子變壓器效率測試</p><p

style="text-indent:25px">變壓器是分為升壓變壓器器和降壓變壓器，在此主要談談降壓變壓器，升壓變壓器類同。檢測方法分為斷電測量和通電檢查。檢測有時難免需要測量變壓器絕緣電阻，大容量的變壓器建議用兆歐表測量，小型變壓器一般可用萬用表的R×10K檔測量，一般為無窮大。當斷電檢查未發(fā)現(xiàn)異常時，就需要通電檢查，將一次繞組接上額定電壓，diangon.com版權(quán)所有。然后測量二次空載電壓，這里有一點要注意的，測量過變壓器的電工老師傅都知道：所有好的變壓，一般測量的空載電壓會比標稱值偏高一些，基于這點也可以反過來用在判斷變壓器的性能上，如果測量的空載電壓偏低的話，建議不要使用，一方面是變壓器自身可能存有故障隱患，另一方面，如果使用可能對整個電路系統(tǒng)都產(chǎn)生影響。安徽變壓器綜合測試器</p></p><br
