| 摘 要： | 基于二维静电场的有限元法,本文采用形状校正法实现了电极形状的优化设计。对优化设计软件中的诸多问题进行了探讨,以保证电场强度的精度,提高优化设计的效率。应用这一方法分别对100kV SF_6绝缘电压互感器内高压绕组均压环和500kV电力变压器高压出线模型套管均压球进行了电极形状优化设计,使其上最大最小电场强度之比分别从1.81和1.68降至1.07。

| Abstract: | A contour correction technique for the optimization of electrode contour i described in this paper. In order to improve the precision of electric field computation and increase the efficiency of optimization, some problems, which are risen from making an optimization code based on the finite element method of two dimensional electrostatic field, are discussedi detail.The applications of the code are illustrated by optimization of high voltage winding shielding electrode in a 100kV SF. insulated voltage transformer and high voltage lead shielding electrode in a 500kV power transformer respectievly.The results show that the rates, between the maximum and the minimum of their electric field strength are reduced to 1.07 from 1.81 and 1.68 respectively. |
