摘　　要：在巴德老化条件下,研究加氢变压器油在老化过程中的族组成变化及油质的老化对介质损耗因数等电气性能的影响,探讨电气性能与族组成变化的关系。结果表明:在巴德老化条件下,随着老化时间的延长,加氢变压器油中芳烃组分保持不变,链烷烃组分逐渐增加,环烷烃组分逐渐减少,加氢变压器油的电气性能变差。Under Baader aging condition, the effects of group composition variation of hydrogenated transformer oil during aging process on the electrical properties such as dielectric loss factor were studied, and the relationship between the electrical properties and group composition variation were discussed. The results show that under Baader aging condition, with the aging time prolonging, the aromatic composition almost stays constant, while the alkane composition increases gradually and the cycloalkane composition decreases gradually, and the electrical properties of the hydrogenated transformer oil deteriorate.
