Plasma Simulation for Partial Discharge Occurs on Ice-Coated Insulators Considering Three-Dimensional Dlectric Field

基于国内外学者研究总结的覆冰绝缘子机理,考虑覆冰绝缘子结构及表面水膜的情况,对覆冰绝缘子进行三维电场仿真,分析了冰棱对电场分布的影响。建立等离子介质阻挡放电(DBD)模型,模拟气隙击穿过程中的放电过程,分析结果可为三维电场覆冰绝缘子研究提供参考。

Based on the study and summarized of icing insulators by scholars at home and abroad,considering the icing structure of the insulators and the water film on it's surface,a three-dimensional electric field simulation of the icing insulators is carried out.The influence of the ice edge on the electric field distribution is analyzed.Based on this conclusion,a plasma dielectric barrier discharge(DBD)model is established to simulate the discharge process in the air gap breakdown process.The analysis results provide a reference for the study of ice-covered insulators in three dimensional electric field.
