摘要

大规模电磁场求解计算时

通常采用有限元法会面临计算与存储量庞大、求解效率较低的问题

为此考虑采用区域分解法来解决。笔者在阐述区域分解法求解原理后

建立了特高压隔离开关气室三维电场问题模型

并将计算结果与整体法所求结果进行比较

结果表明

采用区域分解法有效缓解了存储空间限制、提高了求解效率。同时采用基于参数化设计语言（APDL）的电场能量法对隔离开关气室电容参数进行计算

将计算值与测试值进行比较

两者相对误差小于4%

获得较为准确的分布电容参数

进而为特高压GIS中快速暂态过电压（VFTO）的研究奠定基础。

Abstract

The large calculation amount and storage

and low efficient solution have been confronted when solving large engineering electromagnetic problems by finite element method

therefore

the domain decomposition method was taken into account to solve this problem.The 3D electric field model of UHV disconnector（DS） was set up after expounding the principle the domain decomposition method

the results calculated by which were compared with those of calculation by integrated method

which demonstrated that the storage space constrain was mitigated and the efficiency was enhanced by domain decomposition method.Then the capacitance parameters of DS chamber were calculated by means of electric field energy programmed by APDL.The calculated values were compared with measured ones

the relative error between which was less than 4%.The more precise distributed capacitances obtained lay the foundation for VFTO researched in UHV GIS.
