摘要随着以环氧树脂为主绝缘介质的电气设备的推广,环氧树脂的绝缘劣化问题受到广泛关注。为研究环氧树脂在热积累作用下所产生的绝缘劣化问题,展开热氧老化试验研究。结果表明：热质量损失率随老化时间均匀变化,可较好地预测使用寿命;局部放电量（PD）、介质损耗角正切值（tanδ）、相对介电常数（ε_r）均呈现分段式变化趋势,体积电阻（Ω_r）仅在临近老化终点显著下降;醚键的大量断裂是导致材料绝缘失效的主要原因;环氧树脂随老化时间的增加,表面分裂形成颗粒状物质,裂隙增多,间距加大,为环氧树脂的绝缘状态监测提供参考。

Abstract：With the popularization of electrical equipment that uses epoxy resin as the main insulating medium, the insulation degradation of epoxy resin has been widely concerned. In order to study the insulation degradation caused by epoxy resin under thermal accumulation, thermal oxygen aging test was carried out. The results show that the thermal mass loss changes uniformly with aging time, and the service life can be predicted well. Partial discharge (PD), dielectric loss angle tangent (tanδ ) and relative permittivity (ε_r) all show a piecewise trend, while the resistance (Ω_r) only decreases significantly near the end of aging. Ether cleavage is the main cause of material insulation failure. As the aging time increases, the surface of the epoxy resin splits to form granular materials, the cracks increase, and the spacing increases, which provides a reference for insulation status monitoring of epoxy resin.

Key words： Epoxy resin insulation parameters thermo-oxidative aging insulation condition monitoring
