雷击建筑物时电流分布的计算

Calculation of Current Distribution in a Building under Direct Lightning Stroke

采用有损长线π型等效电路计算了雷直击建筑物时雷电保护系统结构上的电流分布。对雷电保护系统电路模型进行了分析，讨论了不同因素对电流分布的影响。

This paper presents a method for calculating current distribution in a lightning protection system when lightning directly strikes to a building using π type equivalent circuits. The paper analyses the electrical circuit model as well as the influence of different factors on current distribution.
