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(shí)將高低壓測試線接反，這種情況在常見變比測試儀會(huì)將儀器損壞。在一些新測試儀中加裝了保護(hù)裝置，測試線接反時(shí)會(huì)將測試回路的保險(xiǎn)絲熔斷。2、測試值與計(jì)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(xiàng)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(dǎo)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(duì)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(duì)已經(jīng)測試合格的變壓器進(jìn)行復(fù)測，與合格數(shù)據(jù)進(jìn)行對(duì)比。2、將高低壓側(cè)測試線鉗A-a；B-b；C-c夾住，進(jìn)行測試，高頻電子變壓器規(guī)格型號(hào)，高頻電子變壓器規(guī)格型號(hào)。此時(shí)變比測量結(jié)果應(yīng)該為1，高頻電子變壓器規(guī)格型號(hào)。部分廠家不建議用此方法測試，存在一定的爭議。變壓器在出廠之后都會(huì)接受檢測，并且在使用期間也會(huì)定期對(duì)它進(jìn)行檢測。高頻電子變壓器規(guī)格型號(hào)</p><div

style="text-indent:25px">變壓器的品質(zhì)好壞對(duì)聲音的影響很大，因?yàn)樽儔浩鞯膫鬏斈芰颗c鐵芯、線圈密切關(guān)聯(lián)，其傳遞速率對(duì)聲音的影響起決定性作用。像EI型變壓器，人們通常覺得它的中頻比較厚，高頻則比較纖細(xì)，為什么呢?因?yàn)樗膫鬏斔俣认鄬?duì)比較慢。而環(huán)型呢?低頻比較猛，中高頻則又稍弱一點(diǎn)，為什么?因?yàn)樗鼈鬏斔俣缺容^快，但是如果通過有效的結(jié)構(gòu)改變，你就可以把環(huán)型和EI型都做得非常完美，所以關(guān)鍵還是要看你怎么做。不過至少可以肯定一點(diǎn)的是，R型變壓器不是太容易做好。用它來做小電流的前級(jí)功放和CD唱機(jī)電源還可以，如果用來做后級(jí)功放的電源，則有比較嚴(yán)重的缺陷。因?yàn)镽型變壓器本身的結(jié)構(gòu)形式不太容易改變，而環(huán)型和EI型則相對(duì)容易通過改變結(jié)構(gòu)來達(dá)到靚聲目的。采用R型變壓器制作的功率放大器電源，通常聲音很板結(jié)而匱乏靈氣，低頻往往沒有彈跳力而顯得較硬。山東自動(dòng)變壓器測試測量變壓器低壓側(cè)時(shí)，所有人員應(yīng)與高壓側(cè)保持適當(dāng)安全距離。</p><div

style="text-indent:25px">現(xiàn)場操作要點(diǎn)：1.測試時(shí)必須正確記錄分接開關(guān)的位置。應(yīng)盡可能將被測試變壓器的分接開關(guān)放置在第1分接，特別對(duì)有載調(diào)壓變壓器，以獲取較較全的繞組信息。對(duì)無載調(diào)壓變壓器，應(yīng)保證每次測量在同一. 分接位置，便于比較。2.繞組變形測試應(yīng)在解開變壓器所有引線的前提下進(jìn)行，并使這些引線盡可能地遠(yuǎn)離變壓器套管(周圍接地體和金屬懸浮物需離開變壓器套管20cm以上)，尤其是與封閉母線連接的變壓器。3.測試儀的接地沒有連接正確前，不要開始繞組變形測試。4.繞組變形測試應(yīng)放在直流類試驗(yàn)之前或交流類試驗(yàn)之后。5.試驗(yàn)中如變壓器三相頻響特性不一致，應(yīng)檢查設(shè)備后測試，直至同一相兩次試驗(yàn)結(jié)果-致。</p><p style="text-indent:25px">我們選擇試驗(yàn)變壓器時(shí)，主要考慮以下幾點(diǎn)：（1）電壓。依據(jù)試品的要求，首先選用具有合適電壓的試驗(yàn)變壓器，使試驗(yàn)變壓器的高壓側(cè)額定電壓Un高于被試品的試驗(yàn)電壓Us,即Un>Us。其次應(yīng)檢查試驗(yàn)變壓器所需的低壓側(cè)電壓，是否能和現(xiàn)場電源電壓，調(diào)壓器相匹配。（2）電流。試驗(yàn)變壓器的額定輸出電流In應(yīng)大于被試品所需的電流Is，即In>Is。被試品所需的電流可按其電容估算，Is=Us w Cx，其中Cx包括試品電容和附加電容（F）。（3）容量。根據(jù)試驗(yàn)變壓器輸出的額定電流及額定電壓，便可確定試驗(yàn)變壓器的容量，即P=UnIn。根據(jù)部頒標(biāo)準(zhǔn)規(guī)定，我國試驗(yàn)變壓器的電壓等級(jí)有：5、10、25、35、50、100、150、300kV等；容量等級(jí)有：3、5、10、25、50、100、150、200kVA等。由計(jì)算結(jié)果，查部頒標(biāo)準(zhǔn)即可選出所需要的試驗(yàn)變壓器。如有特殊要求，一般可向制造廠商訂購特殊規(guī)格的試驗(yàn)變壓器。變壓器對(duì)電子元器生產(chǎn)要求還是比較高的。</p><div

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(shí)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(yàn)時(shí)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(yàn)中可將其打開，分別測量幾個(gè)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(jí)縮小量程，以避免損壞儀表。一定要在電流穩(wěn)定后再計(jì)數(shù)，必要時(shí)需采取縮短充電時(shí)間的措施。湖南電子變壓器極性測試</p><p style="text-indent:25px">日常在使用變壓器的時(shí)候要注意使用規(guī)范。高頻電子變壓器規(guī)格型號(hào)</p><p style="text-indent:25px">變壓器幾乎在所有的電子產(chǎn)品中都要用到，它原理簡單但根據(jù)不同的使用場合（不同的用途）變壓器的繞制工藝會(huì)有所不同的要求。變壓器的功能主要有：電壓變換；阻抗變換；隔離；穩(wěn)壓（磁飽和變壓器）等，變壓器常用的鐵心形狀一般有E型和C型鐵心。一般降壓變壓器一次繞組的電阻值為幾十至幾百歐，二次繞組為幾歐至幾十歐，這點(diǎn)要做到心中大致有數(shù)，為選萬用表的量程提供參考，一般選用萬用表的R×1或R×10檔，分別測一次繞組和二次繞組，查看有無斷路和短路問題，這個(gè)方法有個(gè)缺點(diǎn)就是，無法檢測出局部短路問題，這個(gè)缺憾可以通過通電檢查彌補(bǔ)。高頻電子變壓器規(guī)格型號(hào)</p></p><br
