摘要
本文把电场计算和电路分析相结合用于大型高压空心电力电抗器均压环的设计,给出了一个完整的设计流程.首先由电场计算求取电抗器各部分的对地分布电容和匝间电容,进而用电路分析的方法求取方波电压作用下电抗器线圈的初始电位分布,再由初始电位分布的合理与否决定均压环的几何尺寸、安装位置和安装数目.
A computer aided designing procedure for screening electrodes of a large multiple-package air core power reactor is presented. The reactor-to-ground stray capacitance and the capacitance between turns of the reactor are calculated numerically by electrostatic field calculation. The initial potential distribution along the axial length of a reactor stressed by a unit step is determined by network analysis. The dimension, the position and the number of the screening electrodes are determined according to the initial potential distribution.
