| 摘 要： | 在防雷和电磁兼容设计中,等电位连接是非常重要的概念。本文采用电路法计算分析建筑物遭直接雷击时金属构架上的节点暂态电压分布。数值计算结果表明,等电位的概念只在有限区域内适用。等电位连接的有效性取决于设备地线的连接方式．并给出了提高等电位连接有效性的建议。

| Abstract: | The concept of "equipotential bonding" is very important in EMC and lightning protection design.Based on the circuit approach,this paper investigates the distribution of the node voltage on building structures during a direct lightning stroke.The simulation results have shown that the concept of "equipotential" is only applicable in a limited area.The effectiveness of the equipotential bonding measures depends on the connecting way of the ground wire of the equipment.Some suggestions for effective equipotential bonding are also given. |
