變壓器是一種相對(duì)靜止的電氣設(shè)備，由繞在同一個(gè)鐵心上的兩個(gè)或兩個(gè)以上的繞組組成的，繞組之間通過交變的磁通的相互聯(lián)系。為了把發(fā)電廠發(fā)出的電能經(jīng)濟(jì)的傳輸、合理的分配以及安全的使用，都要用到電力變壓器。 </p> <p> 2、變壓器工作原理 </p> <p> 簡(jiǎn)單說變壓器的工作原理就是“電生磁，磁生電”。變壓器的初級(jí)（一次）線圈和次級(jí)（二次）線圈共同繞在一個(gè)鐵芯上，當(dāng)一次線圈通入電壓U1后，在鐵芯中產(chǎn)生交變磁通，這個(gè)磁通穿過一次繞組和二次繞組，根據(jù)電磁感應(yīng)定律，在一次繞組和二次繞組中分別產(chǎn)生感應(yīng)電勢(shì)E1和E2。根據(jù)電磁感應(yīng)定律可知，一次側(cè)、二次側(cè)繞組的感應(yīng)電勢(shì)分別為：E1/E2=U1/U2=N1/N2=K(k為變比) </p> <p> <br /> </p><p style="text-indent:25px">在直流電阻測(cè)試完成后,變壓器有時(shí)會(huì)有剩磁,造成不能立即運(yùn)行的情況出現(xiàn),在測(cè)試完成后，將測(cè)試線正負(fù)極顛倒,進(jìn)行一下反向充電,可有效避免上述情況出現(xiàn)。具體時(shí)間根據(jù)變壓器容量不同，以及測(cè)試電流的大小,靈活掌握。有載調(diào)壓的變壓器測(cè)量高壓側(cè)電阻時(shí)從1或17zui大電阻檔開始測(cè)量。為節(jié)約時(shí)間，測(cè)試過程中可按復(fù)位鍵，不必等待放電過程結(jié)束,便可直接再次氣動(dòng)測(cè)量。量程范圍內(nèi)盡量選用大電流以增強(qiáng)穩(wěn)定性能，同時(shí)也應(yīng)考慮試品電流的承受能力。變壓器的基本型式，包括兩組繞有導(dǎo)線之線圈，并且彼此以電感方式稱合一起。</p><div

style="text-indent:25px">變壓器鐵芯的硅鋼片含硅量越大就越好嗎：未見得，矽鋼片含硅量的大小對(duì)變壓器的質(zhì)量影響不是很大，而有取向和無取向則和鐵芯的型號(hào)有關(guān)系。其次，即使是同樣型號(hào)的鐵芯如果你工藝處理不好，那品質(zhì)差別也是很大的，其差別有時(shí)甚至高達(dá)百分之四五十。好的鐵芯而同樣的材料其熱處理和線卷繞制工藝十分關(guān)鍵，良好的熱處理只需很小的10mA激磁電流就能達(dá)到15000高斯，而不好的熱處理則可能要50mA的激磁電流才能達(dá)到相應(yīng)的15000高斯，這二者之間的懸殊差別是很大的。從專業(yè)的角度來判斷鐵芯的好與不好，主要是通過激磁電流、鐵損耗、飽和參數(shù)幾項(xiàng)指標(biāo)來進(jìn)行綜合性評(píng)價(jià)。測(cè)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。四川電子變壓器檢測(cè)單位</p><p

連接并聯(lián)支路的一端，測(cè)量各同名端的電勢(shì)差，其電勢(shì)差應(yīng)等于零；為了避免由于回路接觸不良造成電勢(shì)差為零，允許在測(cè)量中加入一匝，使電勢(shì)差為1V；臨時(shí)匝應(yīng)分別正繞與反繞串入回路，其電勢(shì)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(shì)差減小的現(xiàn)象，測(cè)量電勢(shì)差的電壓表應(yīng)盡量采用高內(nèi)阻的電壓表； (4) 電勢(shì)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(cè)量幾個(gè)并聯(lián)支路的電勢(shì)差，以降低被試?yán)@組的電位； (5) 測(cè)量?jī)x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。成都變壓器在線監(jiān)測(cè)</p><p
