style="text-indent:25px">變壓器測試儀功能特性：1. 所有測試結(jié)果均自動進行相關(guān)校正。儀器可自動進行諸如：波形校正、溫度校正、非額定電壓校正、非額定電流校正等多種校正，使測試結(jié)果準確度更高。2. 320x240大屏幕、高亮度的液晶顯示，全漢字菜單及操作提示實現(xiàn)友好的人機對話，觸摸按鍵使操作更簡便，寬溫液晶帶亮度調(diào)節(jié)，可適應(yīng)冬夏各季。3. 儀器可以由用戶預(yù)設(shè)40組被試品參數(shù)，而且這些參數(shù)可以根據(jù)需要隨時刪除和增加，使用非常方便。4. 自帶實時電子鐘，自動記錄試驗的日期、時間利于實驗結(jié)果的保存、管理。5. 面板式熱敏打印機，可現(xiàn)場快速打印試驗結(jié)果。6. 數(shù)據(jù)（試品設(shè)置、測量結(jié)果、測試時間等）具備掉電存貯及瀏覽功能，可以存儲500組實驗結(jié)果，能與計算機聯(lián)機傳送數(shù)據(jù)。允許外接電壓互感器和電流互感器進行擴展量程測量，可測量任意參數(shù)的被試品。湖北試驗變壓器在變壓器發(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）。</p><div

style="text-indent:25px">變壓器的制作中，線圈的機器繞制和手工繞制各有什么優(yōu)缺點:機器繞制變壓器的優(yōu)點是效率高且外觀成形漂亮，但繞制高個子小洞眼的環(huán)型變壓器卻比較麻煩，而且在絕緣處理工藝的可靠性方面反不如手工繞制到位。手工繞制可以將變壓器的漏磁做得非常小，其在繞制過程中能針對線圈匝數(shù)的布局隨時予以調(diào)整，所以真正的Hi–END變壓器一定是純手工繞制，純手工繞制的缺點是效率低、速度慢。進口放大器中，環(huán)型變壓器的應(yīng)用仍然是主流，這基本說明了一個問題。發(fā)燒友對變壓器的評價要客觀公正，你不能拿一個沒做好的東西作參考而說它不好。有人說環(huán)型變壓器容易磁飽和，那你為什么不去想辦法把它做到不容易磁飽和?而原本通過技術(shù)手段是可以做到這一點的。不下足功夫或者一味地為了省成本，那它當然就容易磁飽和了。同理，只要你認真制作，EI型變壓器的效率也是能做到很高的。</p><p style="text-indent:25px">下面就將常見變壓器變比測試儀在使用過程中常遇到的問題匯總：1、測試時將高低壓測試線接反，這種情況在常見變比測試儀會將儀器損壞。在一些新測試儀中加裝了保護裝置，測試線接反時會將測試回路的保險絲熔斷。2、測試值與計算值不符，接線組別與銘牌接線組別不符，可能是儀器損壞，也可能是變壓器存在問題。3、測試注意事項夾線鉗必須可靠夾緊，避免測試過程中夾線鉗掉落，在以往測試中發(fā)現(xiàn)，測試中夾線鉗掉落，繼而導致儀器損壞。4、測試過程中禁止觸摸被測試變壓器接線銅牌?，F(xiàn)場對變壓器變比是否損壞的檢測方法；1、用被檢測的變比測試儀對已經(jīng)測試合格的變壓器進行復(fù)測，與合格數(shù)據(jù)進行對比。2、將高低壓側(cè)測試線鉗A-a；B-b；C-c夾住，進行測試。此時變比測量結(jié)果應(yīng)該為1。部分廠家不建議用此方法測試，存在一定的爭議。可自動進行波形畸變校正，溫度校正（提供簡單的溫度校正和附加損耗分別校正兩種方式）。</p><div

style="text-indent:25px">檢測判別各繞組的同名端。在使用電源變壓器時，有時為了得到所需的次級電壓，可將兩個或多個次級繞組串聯(lián)起來使用。采用串聯(lián)法使用電源變壓器時，參加串聯(lián)的各繞組的同名端必須正確連接，不能搞錯。否則，變壓器不能正常工作。I.電源變壓器短路性故障的綜合檢測判別。電源變壓器發(fā)生短路性故障后的主要癥狀是發(fā)熱嚴重和次級繞組輸出電壓失常。通常，線圈內(nèi)部匝間短路點越多，短路電流就越大，而變壓器發(fā)熱就越嚴重。檢測判斷電源變壓器是否有短路性故障的簡單方法是測量空載電流(測試方法前面已經(jīng)介紹)。存在短路故障的變壓器，其空載電流值將遠大于滿載電流的10％。當短路嚴重時，變壓器在空載加電后幾十秒鐘之內(nèi)便會迅速發(fā)熱，用手觸摸鐵芯會有燙手的感覺。此時不用測量空載電流便可斷定變壓器有短路點存在。上海變壓器負載測試</p></p><br
