摘要

对阀厅内部进行金具优化设计

可以有效地改善其表面的电场分布。但将待优化金具置于整体模型中加载计算和单独计算分析的方法

分别会造成增加工作量和产生较大误差等问题。对此

文中提出了基于子模型法的金具表面电场分析及优化设计方法

即从整体模型中精确提取待优化金具的边界条件

并以此为依据在金具周围局部区域的子模型中进行分析及优化设计。为验证所提方法的有效性

分别从理论分析和算例验证两方面进行阐述

之后将其应用于±1 100 k V阀厅内部金具的优化设计中。结果表明

该方法有效避免了对整体模型的反复计算

既保证了计算精度

又提高了计算效率。

Abstract

Optimization of fittings can improve the surface electric field distribution

but if the procession is completed in the whole model or separate calculation will greatly increase the amount of calculation and produce large errors respectively. Therefore

this study used sub-model method to precisely extract the boundary conditions of the single fittings in the whole model for the optimization. The effectiveness of the method validated by the theoretical analysis and numerical examples

then it is applied to the optimization design of the internal fittings of the ±1 100 kV valve hall. This method can avoid the repeated calculation of the whole model in the optimization process

which not only ensures the accuracy of the calculation

but also reduces the amount of calculation.
