摘　　要：用旋转氧弹法加速了变压器油的老化。动态地测定了老化后的加氢变压器油和环烷基变压器油的碳族组成,T501含量和界面张力的变化,发现加氢变压器油的抗氧化性能优于环烷基变压器油。The aging of transformer oils were accelerated by rotating pressure vessel method.The changes of carbon compositions,content of T501 and interfacial tension of aged hydrogenated transformer oils and naphthenic transformer oils were measured dynamically,it was found the antioxidative ability of hydrogenated transformer oils was superior to that of naphthenic transformer oils.
