【摘要】 应用ANSYS数值计算软件包对同轴结构电极同轴电场的边缘效应进行较详尽的仿真研究。当内电极直径变化,保持内外电极半径差值相等,分析内电极直径变化时同轴电场边缘效应的变化,指出边缘效应沿径向呈倒U形分布,随着内电极直径的增加,不同电极空间相应位置上电场受边缘效应的影响减弱。这些结论对于固液体交接面闪络特性研究实验电极的设计具有重要的指导意义。更多还原

【Abstract】 A rather elaborate study of the brim-effects of coaxial electric field in coaxial electrode structure is carried out through ANSYS software package in this paper. The coaxial electrode brim-effects will decrease on the corresponding special point in different dimensional coaxial electrode structure with only increasing dimension of internal electrode diameter as well as keeping invariable difference between internal and external electrodes, on the other hand, the brim-effects of coaxial electrode structure show inverse U shape along radial direction, which is not sure to be attained by analytic method.更多还原
