摘要

本文介绍了改性薄膜脉冲电声系统的热梯度模拟结果与实际观测结果的比较，以及室温和50℃下热梯度对空间电荷的影响。结果表明，热梯度的存在有利于电荷注入和电场畸变，导致高压直流下绝缘加速老化。

The effect of thermal gradient on space charge pattern in XLPE

This paper describes the comparison between the simulated results of thermal gradient using COMSOL and actual observed results of thermal gradient in modified thin film pulsed electroacoustic system, together with the effect of thermal gradient on space charge at room temperature and 50 °C. The results show the presence of thermal gradient facilitates the charge injection and electric field distortion, resulting in accelerated aging of insulation under HVDC.
