Numerical evaluation of interception performance for ultra-high lightning rod system

  • 摘要: 针对目前超高避雷针系统日趋增多但现行标准又难以对其整体接闪效能进行有效评价的现状,基于亚网格技术发展了一种地物装置接闪效能数值评估方法,建立了超高避雷针系统接闪效能的数值评估模型,并对典型超高避雷针系统的接闪效能进行了数值评估实验,结果表明:超高避雷针系统接闪器顶端接闪概率最大,但其上部其他区域也可能遭受雷电的侧击,且接闪器上部遭受侧击的概率会随着侧击点高度的增加而增大。此外,雷击强度或雷云荷电强度对超高避雷针系统接闪器上各部分的接闪概率也有影响。雷击强度或雷云荷电强度越小,接闪器顶端的接闪概率越低,相应地接闪器上遭受侧击的概率越大,且侧击点的覆盖范围也会随之逐渐向接闪器的下部扩展。
