雷电迎面先导过程中瞬态电磁场的检测与分析

Detection and analysis of lightning transient electromagnetic field in the face of the pilot process

雷电是大气运动的一种放电现象.雷电释放能量很大,它在短时间内可以释放数百兆焦耳的巨大能量;除了直接雷击带来的危害之外,同时引发强烈的雷电电磁脉冲,对雷电附近的电力系统以及通讯设备等都会造成极大的危害。要控制雷电的发展方向,影响雷电形成的初级阶段是一个重要的突破口。为了进一步了解雷电初级阶段产生的电磁场分布以及将来设计新型抗雷电电磁干扰系统打下基础,文章总结了近年来电磁场的检测方法与分析方法。

Lightning is a discharge phenomenon of atmospheric motion, it can release Hundreds of megabytes tremendous energy. Except for damage of direct lightning striking, a strong lightning electromagnetic pulse can do harm to the power system and communications equipment. In order to control the development direction of lightning, we should control the initial stage of lightning formation. This article summarizes the detection and analytic methods of the electromagnetic field in recent years, in order to lay the foundation for further understanding of the initial stage lighming electromagnetic fields distribution and design new anti-lightning electromagnetic interference system.
