长接地棒/极的冲击电流分布特性

Impulse Currem Distribution of Long Grounding Rod/Pole

以往对接地极和接地棒的接地特性已进行了大量的研究工作，但是却很少涉及接地体上电量的分布特性，而这对解决某些防雷问题又是必不可少的．介绍了以现场试验为基础，对长接地体（棒／极）的冲击电流分布特性进行了较为细致的研究，并给出了相应的经验计算公式。

It is a long time sinee the people began to study the grounding effect of a rod or pole,but no one systematically dcaled with the impulse current distribution. This charactcristic is exactly nccessary for solving some anti-lightning problems. Based on the ground test this paper will systematicaly rescarch the impulse current distribution of long grounding body (rod or pole),the empirical calculating formulas are given simultaneously.
