摘要

估算直接雷击产生的瞬态磁场对于保护工业设施中的敏感电子设备至关重要。估计的准确性取决于方法和模型的代表。在文献中可用的不同替代方法中,全波方法通常是最可靠的。然而,结果仍然存在不确定性,因为考虑模型中电磁环境的所有组成部分实际上是不可能的。为了验证钢筋混凝土结构在全波模拟中的表现,在本文中,我们将两个相互连接的钢筋混凝土墙之间测量的磁场与使用CST Studio Suite计算的磁场进行了比较。观察到的峰值分布也有类似的趋势;然而,一些调整可能是必要的再现波形。

Measurement of Magnetic Fields Generated by a Lightning Current Flowing Through Reinforced Concrete Walls
Estimating the transient magnetic field generated by a direct lightning strike is essential to protect sensitive electronic devices in industrial facilities. The accuracy of the estimation depends on the approach and the representatives of the model. Out of the different alternatives available in the literature, the full-wave methods are usually the most reliable. Nevertheless, there is still uncertainty in the results because considering all the components of the electromagnetic environment in the models is virtually impossible. To validate the representation of reinforced concrete structures in full-wave simulations, in this paper, we compare the magnetic field measured between two interconnected reinforced concrete walls to the magnetic field computed using CST Studio Suite. Similar tendencies for the distribution of the peak-values are observed; yet, some adjustments may be necessary to reproduce the waveforms.
