摘要

高压电缆绝缘中的电击穿与空间电荷的存在有关。除了实验表征、物理和现象学建模之外，还提出了一种基于计算化学最新发展的替代方法，该方法可以提供每个单独陷阱的信息。本文给出了一种用从头算方法将分子模拟结果与一些宏观特征联系起来的方法。第一个结果显示了与绝缘中不同缺陷相关的捕获行为。

Identification of space charge in cable insulation: a new approach using molecular simulation

Electrical breakdown in high voltage cable insulation is correlated with the presence of a space charge. Beside experimental characterisation, physical and phenomenological modelling, an alternative approach is proposed, based on recent developments in computational chemistry, which can give information on each individual trap. The paper shows a way to relate the results from molecular simulation by ab-initio methods to some macroscopic features. First results show the trapping behaviour associated to different defects in the insulation.
