摘要: 根据IEC 62305—2:2010标准中介绍的雷击风险的评估流程,在前人提出的适合雷击大型户外空旷区域风险计算方法的基础上,笔者结合大型户外空旷区域的具体闪电定位资料,精细化地研究了雷电可能为该区域带来的风险,主要分析了大型户外区域内雷电直接击中人体导致人员伤亡的概率PB、最小雷电流I、滚球半径hr,并举例说明了大型户外空旷区域精细化雷击风险评估的具体计算方法,以期为大型户外空旷区域的直击雷防护设计提供依据。

Abstract: In accordance with the evaluation method of lightning strike risk in IEC 62305-2:2010 standard, based on quantitative formula of lightning strike risk evaluation method for the large wild area, and the lightning location data in the large wild area, the authors made a detailed study about the certain risks that lightning strike might cause in the large wild area, analyzed the probability (PB) when it striked humans directly in the large wild area, the peak current (I) and rolling sphere radius (hr), and also took examples to introduce the specific calculating method of lightning strike risk in the large wild area aiming at providing the basis for the design of direct lightening strike protection in the large wild area.
