摘要

当长时间对绝缘材料施加高电场时,绝缘材料中会注入空间电荷。空间电荷使绝缘材料中的电场发生畸变,降低了绝缘性能。为了阐明空间电荷的影响,对均匀材料进行了一维模拟。然而,复合材料中的空间电荷行为不能用均匀材料的模拟技术来计算。因此,我们开发了一种利用有限元方法模拟复合材料空间电荷行为的二维模拟技术。

複合材料における空間電荷挙動の2次元シミュレーション手法の構築
When a high electric field is applied to an insulating material for a long time, space charge may be injected into the insulating material. Space charge distorts the electric field in the insulating material and reduces the insulating performance. To elucidate the effects of space charge, one-dimensional simulations have been reported for homogeneous materials. However, space charge behavior in composite materials cannot be calculated using simulation techniques for homogeneous materials. Therefore, we have developed a two-dimensional simulation technique for space charge behavior in composite materials using the finite element method.
