针对实验室不同老化程度和不同温度下的油纸绝缘模型，开展频域介电谱试验，基于普适弛豫定律，从频域介电谱的实验数据中提取了频域特征量fp，研究了特征量fp与油纸绝缘模型不同老化程度、不同温度之间的关系。结果表明：特征量fp随老化程度的加深和温度的升高而呈现规律性递增，将该特征量用于变压器等油纸绝缘设备状态评估具有一定的可行性。
The frequency domain spectrum (FDS) experiments of oil-paper insulation models under various aging degrees and temperatures were developed, and the frequency domain characteristic parameter fp was extracted from FDS data based on the universal relaxation law, and then the characteristic parameter fp of the oil-paper insulation with various aging degrees under different temperatures were studied. The results show that the characteristic parameter fp increases with the increase of aging degree and temperature, which can be used to evaluate the condition of oil-paper insulation equipments.
