Abstract Not only moisture, acid and other impurities produced in the aging process of oil impregnated paper have catalytic effect on the aging, but also the polar products participate in the dielectric response process of the material. In order to use the characteristic of traditional aging dynamic model in describing the aging process of oil impregnated paper from the perspective of micro molecular chain fracture, as well as the nondestructive, fast measurement characteristics of frequency domain spectroscopy to better analysis the aging process of oil impregnated paper, a separation method of different dielectric response processes was proposed to analyze the frequency domain spectroscopy curves of different aged oil impregnated paper samples by the analysis and theoretical derivation of oil impregnated paper aging. The concepts of aging modified translation coefficient and time-varying pre-exponential factor were proposed. The aging modified model was obtained by introducing the aging modified translation coefficient and time-varying pre-exponential factor into the traditional aging dynamic model, and the oil impregnated paper samples with different aging degree were prepared. The degree of polymerization and frequency domain spectroscopy of the samples were tested, and the modified aging kinetics model was introduced the degree of polymerization and time curve to verify the correctness of the model. Finally, an aging evaluation method for oil impregnated paper was proposed and the effectiveness of this method was verified by experiments. The results show that the modified aging model based on the aging modified translation coefficient and time-varying pre-exponential factor can well fit the curve of degree of polymerization, which verifies the effectiveness of the proposed aging modified translation coefficient and time-varying pre-exponential factor. Based on this relationship, an aging evaluation method was proposed, the relative error of this evaluation method is small, which can be used to evaluate the aging of oil impregnated paper.

Key words： Aging of oil impregnated paper modified aging kinetic model aging assessment aging modified translation coefficient time-varying pre-exponential factor
