【摘要】 为了优化高压标准电容器的电场分布,利用面电荷密度计算包含导体和电介质材料的无限大空间电场。假设电极上的自由电荷连续分布,两种介质分界面上存在着连续分布的束缚电荷,以节点的面电荷密度为变量,利用线性插值来表示这些连续分布的电荷,根据边界条件和分界面条件建立联立线性方程组。计算结果表明,通过改变均压环的高度,可以优化电容器外部的电场,使最大场强降低到临界值。更多还原

【Abstract】 In order to optimize the electric field of high voltage standard capacitor,surface charge density method is used to calculate the electric field which is an infinite field with conductor and dielectric material.This method supposes that free charges distribute continuously on the surface of conductor and bound charges exist on the interface of two dielectrics,then expresses surface charges density by linear interpolation and forms the simultaneous linear equations by boundary or interface condition.Optimization shows that the maximum of electric intensity in the air can be reduced to a certain limitation by adjusting the height of voltage balance ring.更多还原
