摘要:
变压器的绝缘介质极化过程缓慢,测量稳定的绝缘电阻值需要长时间等待,为缩短测量时间,文中研究一种绝缘电阻的参数估计测量方法。首先建立油纸绝缘的扩展德拜模型;在极化/去极化电流测试基础上,用矩阵束算法估计去极化电流参数,得到介质极化稳定后的绝缘电阻值。实验结果表明,该方法能消除吸收电流带来的误差影响,缩短绝缘电阻测量时间。
Abstract:
The polarization process of insulation dielectric of transformer is slow, and it takes a long time to measure the stable insulation resistance. In order to shorten the measurement time,a parameter estimation measurement method of insulation resistance is studied in this paper. Firstly, the extended Debye model of oil-paper insulation is established. Based on the polarization/depolarization current test,the depolarization current parameters are estimated by matrix pencil algorithm, and get the insulation resistance after dielectric polarization stabilization.The experiment results show that the error caused by absorption current can be eliminated. Meanwhile, shortened the measurement time of insulation resistance.
