Research Progress in Surface Charge Characteristics of Solid Insulating Materials

固体绝缘材料在电气、航空航天等领域得到了广泛应用,积聚在气体-固体或真空-固体交界面处的表面电荷被认为是导致电场畸变、造成固体材料表面绝缘性能下降的重要因素,因此成为研究者关注的热点问题之一。论文总结了近年来固体绝缘材料表面电荷特性的相关研究,分别从测量方法、反演算法、电荷积聚和消散规律及机理、表面电荷对材料绝缘性能的影响及表面电荷的调控方法这5个方面对表面电荷特性的研究现状进行评述,并对后续的研究给出了建议,旨在为今后固体绝缘材料表面电荷的相关研究提供参考。

Solid insulating materials have been widely used in the fields such as electrical and aerospace engineering, and the surface charge accumulated in gas-solid or vacuum-solid interface has been recognized as the primary reason for causing electric field distortion and the reduction of surface insulation property, thus it is becoming one of the hottest research topics. We summarize and review the related research progress in surface charge of solid insulating materials, including the measurement methods, calibration algorithms, charge accumulation and decay behaviors, the influence of the charge on surface insulation property and the controlling methods of surface charge. Meanwhile, we put forward the suggestions for the ensuing researches so as to provide a reference to surface charge related research in the future.
