摘要

聚丙烯具有优良的电性能，是一种潜在的环保型高压直流电缆绝缘材料。直流电压下空间电荷注入和积累特性是导致介质击穿的重要因素。基于双极电荷输运模型，利用有限元仿真软件模拟了空间电荷和电场畸变特性随升压时间增加的动态演化过程。仿真结果表明，聚丙烯中的电场畸变是由电荷注入的积累引起的，随着时间的增加，当电压达到一定阈值时，电场畸变变得明显。

Simulation of Charge Transport Characteristics of Polypropylene

Polypropylene is a potential environment-friendly insulation material for high voltage DC cable due to its excellent electrical properties. The characteristics of space charge injection and accumulation under DC voltage are important factors of dielectric breakdown. Based on the bipolar charge transport model, this paper used finite element simulation software to simulate the dynamic evolution process of space charge and electric field distortion characteristics with the increase of voltage boosting time. The simulation result indicates that the electric field distortion in polypropylene is caused by the accumulation of charge injection, and the electric field distortion becomes obvious when the voltage reaches a certain threshold with the increase of time.
