多股电缆线电场的边界元方法

Boundary element method of electric field of the strands of electric cables

用边界元方法,研究了多股电缆线电场问题.在控制方程的基础上,利用其基本解,通过加权余量法建立内点和边界的积分方程.对边界剖分进行二次元处理,得到离散化的计算格式,给出了多股并行电缆线不同轴心距下所形成的电场特性.

Electric field question of strands of electric cables was studied by the boundary element method. On the governing equation basic and its basic solutlon,inner point and boundary integral equation was set by weighted residual quantity. Discretizatie calculating form was obtained by the quadratic element deal of boundary subdivision. Electric characteristic of collateral strands of electric cables in different axes distance was given in this article.
