oil），其主要成分為烷烴、環(huán)烷烴、芳香烴等化合物。變壓器油比熱容較大，它吸收熱量體積膨脹上升，在管中形成循環(huán)，再通過散熱裝置將熱量散發(fā)到空氣中。有的變壓器利用氣態(tài)物質(zhì)（如六氟化硫）作為冷卻劑。由于導熱能力的限制，氣體冷卻劑一般應用于小容量變壓器。關(guān)于變壓器油，絕大多數(shù)采用的是礦物油, 極少數(shù)的變壓器采用的是植物油。礦物油泄露可能會對環(huán)境造成污染，而植物油污染程度就會少很多。而且植物油的閃點要比礦物油的高。所以，在將來，植物油可能會取代礦物油。變壓器繞組檢測空載損耗當額定頻率下的額定電壓（分接電壓）施加到一個繞組的端子。</p><div style="width:100%;text-align: center;"><img style="max-width:

關(guān)于變壓器容量計算的一些問題1、變壓器的額定容量，應該是變壓器在規(guī)定的使用條件下，能夠保證變壓器正常運行的比較大載荷視在功率；2、這個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載的視在功率；3、變壓器額定運行時，變壓器的輸出視在功率等于額定容量；4、變壓器額定運行時，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，一般認為變壓器額定運行時，變壓器的輸入視在功率等于額定容量，由此進行的運算及結(jié)果也是基本準確的；6、所以在使用變壓器時，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)；7、有人認為變壓器有損耗，必須在額定容量90%以下運行是錯誤的！8、變壓器在設計選用容量時，根據(jù)計算負荷要乘以安全系數(shù)是對的?？梢钥吹阶儔浩魅萘坑嬎闫鋵嵅浑y。主要是要注意變壓器容量計算的一些問題。

style="text-indent:25px">對于三角形聯(lián)結(jié)的繞組進行三相試驗時，如果低壓側(cè)為星形聯(lián)結(jié)，可采用測量低壓電流的方法；對于三角形聯(lián)結(jié)的繞組進行單相試驗時，單相電壓應施加在三角形的兩個角上，試驗時的電壓應與三相試驗時的相間電壓相同；對于星形聯(lián)結(jié)繞組，如果電源容量不足以進行上述單相試驗，而中性點可以利用且能承受相關(guān)的電流時，經(jīng)協(xié)商單相電源可施加于線端與中性點之間。短路試驗可以采用預先短路、選相合閘，也可以采用預先送電、選相短路的方法。對于單同心式繞組的變壓器采用預先短路時，為了避免zui初幾個周波中由于鐵心飽和產(chǎn)生的勵磁電流疊加在短路電流上，施加電壓的繞組應該選距鐵心較遠的那個繞組。對于雙同心式繞組（高/低/高）和交疊式繞組的變壓器采用預先短路的方法試驗時，制造單位需與用戶協(xié)商。在檢查變壓器的時候需要注意對套管進行定期檢查。</p><div
