先要表明，溫度和溫升是2個不一樣的定義，比如，油浸變壓器評測溫度為65度，這一溫度便是變壓器的具體溫度，如果當初的變壓器周邊(氣體)溫度時三十度，那變壓器的溫升便是65度減三十度相當于35度，大家便說變壓器如今的溫升是35度。油浸變壓器的大溫升為65度。

　　一(yi)般(ban)不允許超(chao)出55度(du)(du)，這(zhe)是(shi)由于在(zai)我國油(you)變(bian)(bian)式變(bian)(bian)壓器(qi)(qi)選用的(de)是(shi)A級絕(jue)緣層(ceng)，高溫(wen)(wen)度(du)(du)極限為(wei)105℃。變(bian)(bian)壓器(qi)(qi)造成溫(wen)(wen)度(du)(du)的(de)位置關鍵在(zai)繞阻和變(bian)(bian)壓器(qi)(qi)鐵芯(xin)，而大家一(yi)般(ban)在(zai)變(bian)(bian)壓器(qi)(qi)油(you)高層(ceng)溫(wen)(wen)度(du)(du)測量，它倆中間大約10℃的(de)溫(wen)(wen)度(du)(du)差，大家要求當然循(xun)環系統、風(feng)冷(leng)變(bian)(bian)壓器(qi)(qi)頂層(ceng)水(shui)(shui)溫(wen)(wen)極限為(wei)95℃。為(wei)使變(bian)(bian)壓器(qi)(qi)油(you)但是(shi)速劣化，頂層(ceng)水(shui)(shui)溫(wen)(wen)一(yi)般(ban)不超(chao)過85℃，當水(shui)(shui)溫(wen)(wen)超(chao)出75℃時(shi)，務必(bi)開展強制(zhi)性風(feng)冷(leng)或(huo)水(shui)(shui)冷(leng)散熱。針對A級絕(jue)緣層(ceng)，由于大溫(wen)(wen)升為(wei)65℃。因此在(zai)我國要求:油(you)變(bian)(bian)式變(bian)(bian)壓器(qi)(qi)運作時(shi)，外溫(wen)(wen)不可超(chao)出40℃。這(zhe)時(shi)變(bian)(bian)壓器(qi)(qi)油(you)高層(ceng)的(de)溫(wen)(wen)升限制(zhi)值為(wei)55℃”
