摘要
依据GB 50057—2010《建筑物防雷设计规范》等相关标准,分析了高层住宅建筑物侧立面太阳能热水器的侧击雷雷电流分布范围,对直击雷电流进行分流计算,比较了10/350μs与8/20μs两种波形雷电流的相关特性,来探讨电涌保护器(SPD)相关电流参数的选型,以提高对雷电电涌的防护精度。
On the basis of relevant standards such as GB 50057—2010,this paper analyzed the sideflash lightning current distribution of solar water heater on the side elevation of high-rise residential building.Based on the lightning current flow calculation,the related characteristics of 10/350 μs and 8/20 μs waveform of lightning current were compared.The related current parameters selections of surge protective device（ SPD） were discussed,in order to improve the accuracy of lightning surge protection.
