style="text-indent:25px">變壓器（Transformer）是利用電磁感應(yīng)的原理來改變交流電壓的裝置，主要構(gòu)件是初級線圈、次級線圈和鐵芯（磁芯）。主要功能有：電壓變換、電流變換、阻抗變換、隔離、穩(wěn)壓（磁飽和變壓器）等。按用途可以分為：電力變壓器和特殊變壓器（電爐變、整流變、工頻試驗(yàn)變壓器、調(diào)壓器、礦用變、音頻變壓器、中頻變壓器、高頻變壓器、沖擊變壓器、儀用變壓器、電子變壓器、電抗器、互感器等）<p>作用：<p>變壓器是一種靜止的電氣設(shè)備。它是根據(jù)電磁感應(yīng)的原理，將某一等級的交流電壓和電流轉(zhuǎn)換成同頻率的另一等級電壓和電流的設(shè)備。作用：變換交流電壓、交換交流電流和變換阻抗。</p><p style="text-indent:25px">在直流電阻測試完成后,變壓器有時會有剩磁,造成不能立即運(yùn)行的情況出現(xiàn),在測試完成后，將測試線正負(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)。具體時間根據(jù)變壓器容量不同，以及測試電流的大小,靈活掌握。有載調(diào)壓的變壓器測量高壓側(cè)電阻時從1或17zui大電阻檔開始測量。為節(jié)約時間，測試過程中可按復(fù)位鍵，不必等待放電過程結(jié)束,便可直接再次氣動測量。量程范圍內(nèi)盡量選用大電流以增強(qiáng)穩(wěn)定性能，同時也應(yīng)考慮試品電流的承受能力。變壓器按用途可以分為：配電變壓器、組合式變壓器、干式變壓器、單相變壓器、整流變壓器、抗干擾變壓器等。</p><div

1、短路阻抗及負(fù)載損耗的測量，應(yīng)當(dāng)在試品的一個繞組的線端施加額定頻率，且近似正弦的電流，另一個繞組短路，各相處于同一個分接位置。測量應(yīng)在50%～100.0%額定電流下進(jìn)行；為避免繞組發(fā)熱對試驗(yàn)結(jié)杲產(chǎn)生明顯誤差，試驗(yàn)測量應(yīng)迅速進(jìn)行；同時準(zhǔn)確記錄試驗(yàn)時繞組溫度。 2、短路阻抗及負(fù)載損耗的測量與空載試驗(yàn)的測量線路相同，只是測量中無需進(jìn)行電壓波形校正。 3、短路阻抗及負(fù)載損耗的測量接線；對于額定電流很小的試品，儀表（電壓表及瓦特表電壓線圈）和電壓互感器的吸收電流在測量電流中不可忽略時，應(yīng)將電壓取于電源。 4、短路阻抗是在額定頻率和參考溫度下，一對繞組中某一繞組端子之間的等效串聯(lián)阻抗；其百分?jǐn)?shù)等于短路電壓與額定電壓之比，測量時應(yīng)以三相電流的算術(shù)平均值為準(zhǔn)。具有聲響放電報警，放電指示清晰，減少誤操作。上海實(shí)驗(yàn)用變壓器選擇</p><p style="text-indent:25px">及時消除故障和補(bǔ)充油，確保油位保持在油標(biāo)1/4-3/4處對于變壓器保持穩(wěn)定是非常有必要的。珠海電子變壓器高壓測試</p><p style="text-indent:25px">儀器特點(diǎn)：1、可顯示各相電壓和電流的實(shí)時波形，直觀的顯示出波形的畸變情況。2、電壓回路寬量限：電壓較大可測量到 750V，不用切換檔位即可保證精度。不會因電壓檔位選錯而對儀器本身有所損壞。3、大屏幕、全漢字菜單及操作提示實(shí)現(xiàn)友好的人機(jī)對話，導(dǎo)電橡膠按鍵使操作更簡便，高亮度的真彩色液晶顯示，可適應(yīng)冬夏各季。 4、用戶可隨時將測試的數(shù)據(jù)通過微型打印機(jī)將結(jié)果打印出來。5、所有的測試結(jié)果可以記錄的形式保存起來，以備查閱。 6、內(nèi)置真時鐘，可實(shí)時顯示當(dāng)前的日期和時間，在存儲記錄時可同時將試驗(yàn)時間存儲下來。珠海電子變壓器高壓測試</p></p><br /><p>文章來源地址:
