摘要

实验研究了热老化前后电缆聚乙烯绝缘的吸收充电电流和放电电流。在麦克斯韦等效电路和沃伊特等效电路两种物理模型的基础上对这些数据进行了分析。本文的目的是为了说明吸收特性的测量是电缆电气绝缘的无损诊断方法。

The absorbtion and low-frequency dielectric characteristics of the cross-linked polyethylene insulation for power cables

The absorption charging Ich and discharging Idis currents of the cable polyethylene insulation before and after thermal aging were investigated experimentally. These data are analyzed on the basis of two physics models which correspond to Maxwell and Voigt equivalent circuits. The aim of the work is to show that measurements of absorption characteristics are nondestructive diagnostic method of electrical insulation of cables.
