前言

變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)作為電(dian)(dian)(dian)力(li)傳輸(shu)紐帶，是(shi)電(dian)(dian)(dian)力(li)系統中最重要(yao)和最昂貴的(de)設備之一，其(qi)安全可靠的(de)經濟運(yun)(yun)行(xing)對(dui)電(dian)(dian)(dian)力(li)系統至關重要(yao)。對(dui)于油(you)浸(jin)式變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)，溫(wen)(wen)度(du)(du)(du)是(shi)造成繞(rao)(rao)(rao)組絕(jue)緣老化(hua)的(de)決(jue)定性因(yin)素，六度(du)(du)(du)法(fa)則(ze)表明溫(wen)(wen)度(du)(du)(du)每上升6℃，A級固(gu)體(ti)絕(jue)緣的(de)老化(hua)率(lv)增加1倍(bei)，即變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)壽(shou)命(ming)降(jiang)低一半，而溫(wen)(wen)度(du)(du)(du)每下降(jiang)6℃變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)壽(shou)命(ming)可延長1倍(bei)，可以說(shuo)能否準確測(ce)量油(you)溫(wen)(wen)及繞(rao)(rao)(rao)組溫(wen)(wen)度(du)(du)(du)直接影響變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)的(de)壽(shou)命(ming)評估。運(yun)(yun)行(xing)溫(wen)(wen)度(du)(du)(du)也是(shi)電(dian)(dian)(dian)網負(fu)(fu)荷(he)調度(du)(du)(du)的(de)直接依據，GB15164《油(you)浸(jin)式電(dian)(dian)(dian)力(li)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)負(fu)(fu)載導則(ze)》變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)負(fu)(fu)載能力(li)的(de)計算方法(fa)中，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)的(de)油(you)溫(wen)(wen)和繞(rao)(rao)(rao)組溫(wen)(wen)度(du)(du)(du)是(shi)重要(yao)的(de)參數，因(yin)此準確可靠的(de)測(ce)量變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)油(you)溫(wen)(wen)及繞(rao)(rao)(rao)組熱(re)點溫(wen)(wen)度(du)(du)(du)是(shi)增加電(dian)(dian)(dian)網的(de)運(yun)(yun)行(xing)方式靈活性，提高(gao)設備的(de)運(yun)(yun)行(xing)效率(lv)的(de)基礎。
