| description | In order to study the influence of temperature on the frequency domain spectroscopy (FDS) characteristics of resin-impregnated paper (RIP) bushings, and more accurately apply the dielectric response technology to the evaluation of bushing damp or aging state, the FDS measurement experiments of RIP bushing insulation at different temperatures are designed in this paper. The dielectric polarization theory is used to analyze the frequency domain dielectric phenomenon, and the extended Debye model is established. The genetic algorithm and interior point method are used to identify the parameters of each branch, and the influence of temperature on FDS characteristics is analyzed through changing the model parameters. The results show that with the increase of temperature, the real part of complex capacitance in low frequency region (10–3~1 Hz) increases significantly, and the spectrum curves of dielectric loss and imaginary part of complex capacitance move to high frequency; the established 6-branch Debye model is basically consistent with the measured values, and the insulation resistance R0 decreases with the increase of temperature while the geometric capacitance C0 basically keeps unchanged; the "frequency temperature shift factor"-based main curve technology can effectively eliminate the influence of temperature and convert the spectrum curve under known temperature to unknown temperature, consequently extending the measurement range of spectrum curve; the "translation factor" of the spectrum curve satisfies the Arrhenius equation, and the activation energy calculated by the "translation factor" is about 31.92 kJ/mol. Therefore, the influence of temperature must be considered when using frequency domain dielectric spectroscopy to evaluate the state of damp or aging, otherwise the evaluation results will be inaccurate. |
