雷击智能建筑时感应电流分布计算方法研究

智能建筑比一般建筑物更容易遭受雷击,而且一旦遭受雷击损失巨大。因此智能建筑的防雷保护要求较高。该文对雷击智能建筑电磁暂态的感应电流进行简化,将防雷系统简化成由一定数量的耦合π型电路组成的等值网络,再利用节点电压法计算出雷电主放电电流分布的时域解。

Induced Current Distribution Computation Research of Intelligent Construction by Struck Lightning

The intelligent construction is easier than the common building to suffer the thunder stroke, moreover, once suffers the thunder stroke loss to be huge. Therefore the intelligent construction’s anti-radar protection request is high. This article carries on the simplification to the thunder stroke intelligence construction electromagnetism transition condition's induced current, The anti -radar system is simplified as the equivalent network which is composed of certain amount's coupling π electric circuit, calculates the thunder and lightning main discharging current distributed time domain solution again using the node voltage law.
