接地体的冲击电阻的分析与计算

Analysis and calculation of the impulsion resistance of the grounding objects

摘要:

在分析雷电电磁脉冲、核电磁脉冲等电磁脉冲(EMP)对地面电子设备可能造成的损害,以及电磁脉冲感应电流在接地体中的散流特性的基础上,给出了简单接地体的冲击接地作用的度量参数和冲击接地电阻的计算方法,并举例求得一个接地体的冲击接地电阻,为实际工程提供理论依据。

Abstract:

Based on the analysis of the damage of thunder-EMP and nuclear-EMP to the electronic equipment, and the dispersing characteristics of the induction current in the grounding objects, the measurement parameters of the impulsion function of the grounding objects and the calculation method of the grounding resistance are given in this paper. And a calculating example that can be referred in the applications is given also.
