摘要

了解负CG对地雷击产生初击穿的过程对防雷系统的设计具有重要意义。我们观察了印度尼西亚热带地区与初步击穿有关的负云对地闪电前的电场变化。研究了初击穿过程产生负一次回程的电场变化特性。结果表明，前回笔划分离的算术平均值为57 ms，几何平均值为32 ms。文中还给出了其他统计参数。

Characteristics of electric field change preceding negative first return stroke produced by preliminary breakdown

Understanding the initiation process of preliminary breakdown during negative CG lightning discharges to the ground is important to design a lightning protection system. We observed electric field change preceding negative cloud to ground lightning flashes related to preliminary breakdown in tropical region, Indonesia. The characteristics of electric field change of negative first return stroke produced by preliminary breakdown process were studied. The results showed that arithmetic mean and geometric mean of pre-return stroke separation is 57 ms and 32 ms, respectively. Other statistical parameters also are shown in this paper.
