coil);而跨于此線圈的電壓稱之為「一次電壓.」。在二次線圈的感應(yīng)電壓可能大于或小于一次電壓，是由一次線圈與二次線圈問的「匝數(shù)比」所決定的。因此，變壓器區(qū)分為升壓與降壓變壓器兩種。中山變壓器參數(shù)測定一般用來檢測變壓器的儀器靈敏度都很高。</p><div style="width:100%;text-align: center;"><img

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(dǎo)熱能力的限制，氣體冷卻劑一般應(yīng)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。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。山東特殊高頻電子變壓器</p><p

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(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(zhǔn)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(shè)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。中山變壓器參數(shù)測定</p><p
