摘要
本文用表面电荷法计算某高压设备三维电场,并采用导体表面展开剖办法,以导体表面离散电荷及不同介质分界面的束缚面电荷为待求量,直接求出导体表面场强及各点电位和空间场强最大值所在点的位置。这种方法剖分准确、计算简单、精确度高。
This article elucidates the Calculation of a 3-dimensional electric fieldof a certain high tension apparatus by means of surface charge method usingmesh division of the developed conductor surface. Based on the discretechages of the conductor surface and the polarisation charges on the boun-dary surface of 2 different dielectrics as the quantities to be determine,dit will then be possible to calculate directly the field intensity on the condu-ctor surface, the potential at various points and the position of the pointat which the field intensity is the maximum. This method will give accu-rate mesh division, simple calculation, accurate results and can entirelysatisfy the requirements in Electric Power Engineering.
