摘要
为分析油纸绝缘系统的介电频谱与其微水含量、温度之间的关系,搭建了基于频率响应的测试装置,测试了油纸绝缘系统的介电频谱。结果表明:频率响应法能有效评估油纸绝缘微水含量信息,油纸绝缘系统的复介电频谱与其微水含量和温度之间存在一个函数关系。
To analyze the relationship between dielectric frequency spectra and trace moisture and temperature of oil-paper insulation system,a testing device based on frequency domain spectroscopy was established to measure the dielectric spectroscopy of oil-paper insulation system.The results show that frequency response method can effectively assess the trace moisture of oil-paper insulation;and there is a functional relationship between complex permittivity of oil-paper insulation,trace moisture and temperature.
