前言进行高压绝缘设计时,确定系统的电场分布是一项重要的工作。它可以通过电解槽等许多模拟或实验的方法求得,也可以用理论方法进行计算。近几年来,国外重视研究采用数学计算解决实际电场问题的方法,其中较普遍采用的是网格法,即用有 Preface When designing high voltage insulation, it is an important job to determine the electric field distribution of the system. It can be obtained through many simulation or experimental methods such as electrolytic cell, and can also be calculated by theoretical methods. In recent years, foreign countries attach great importance to the study of mathematical methods used to solve the problem of the actual electric field, which is more commonly used grid method that is used
