绝缘管型引雷针雷击的数学模拟计算

Numerical Simulation on Lightning Stroke of Insulation-tube Arrester

运用模拟电荷法对普通导体避雷针及绝缘管型引雷针在雷云电场下所形成的电场进行了计算 ,并通过对二者的计算比较 ,认为绝缘管型引雷针所形成的空间场强大于普通避雷针所形成的空间场强 。

It is calculated and compared that the different electric fields are formed by common lighten arrester and insulation tube arrester with the method of stimulated electric charge.It is shown that the strength of the space electric field formed by insulation tube arrester is larger than common arresters.The ability of inducing lighten is stronger than the common arresters.
