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(kāi)，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(kāi)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。河南變壓器參數(shù)測(cè)試變壓器在很多大型設(shè)備中都有使用，所以是一個(gè)比較重要的零件。</p><div style="width:100%;text-align: center;"><img

關(guān)于變壓器容量計(jì)算的一些問(wèn)題1、變壓器的額定容量，應(yīng)該是變壓器在規(guī)定的使用條件下，能夠保證變壓器正常運(yùn)行的比較大載荷視在功率；2、這個(gè)視在功率就是變壓器的輸出功率，也是變壓器能帶比較大負(fù)載的視在功率；3、變壓器額定運(yùn)行時(shí)，變壓器的輸出視在功率等于額定容量；4、變壓器額定運(yùn)行時(shí)，變壓器的輸入視在功率大于額定容量；5、由于變壓器的效率很高，一般認(rèn)為變壓器額定運(yùn)行時(shí)，變壓器的輸入視在功率等于額定容量，由此進(jìn)行的運(yùn)算及結(jié)果也是基本準(zhǔn)確的；6、所以在使用變壓器時(shí)，你只要觀察變壓器輸出的電流、電壓、功率因數(shù)及其視在功率等于或小于額定容量就是安全的(使用條件滿足時(shí))；7、有人認(rèn)為變壓器有損耗，必須在額定容量90%以下運(yùn)行是錯(cuò)誤的！8、變壓器在設(shè)計(jì)選用容量時(shí)，根據(jù)計(jì)算負(fù)荷要乘以安全系數(shù)是對(duì)的。可以看到變壓器容量計(jì)算其實(shí)不難。主要是要注意變壓器容量計(jì)算的一些問(wèn)題。 </p><p style="text-indent:25px">隨著電力工業(yè)的發(fā)展，電力產(chǎn)品的質(zhì)量要求也在不斷提高。尤其是對(duì)變壓器的質(zhì)量要求也較為嚴(yán)格。變壓器的變壓比是變壓器參數(shù)的重要部分。測(cè)量變壓器的變壓比就是測(cè)量變壓器，也叫匝數(shù)比試驗(yàn)。變壓器的變壓比通常為分?jǐn)?shù)值或是小數(shù)，因此，一般采用四舍五入法取整數(shù)，作為變壓器的變壓比。但是，此變壓比與匝數(shù)比之間會(huì)有微小偏差，所以，此誤差應(yīng)控制在允許范圍之內(nèi)。因此，在變壓器投入使用前，要對(duì)變壓器變壓比進(jìn)行測(cè)試。變壓比檢測(cè)常用的方法有雙電壓表法和變壓比電橋法，還有較先進(jìn)的變壓器變壓比自動(dòng)測(cè)試儀等。本次試驗(yàn)采用變壓器變壓比自動(dòng)測(cè)試儀對(duì)變壓器變壓比進(jìn)行測(cè)試。對(duì)于零部件松動(dòng)、接觸不良甚至存在放電現(xiàn)象，應(yīng)及時(shí)斷開(kāi)變壓器跌落保險(xiǎn)，消除隱患。</p><div
