农村民居防雷滚球半径合理性探析

Analysis on Rationality of Rolling Sphere Radius for Lightning Protection of Rural Houses

针对农村民居的特点,分析其易遭受雷击的原因,提出应重视农村民居的防雷;推导农村民居防雷设计中的滚球半径的合理取值;建议在纬度45°以内地区小体量的建筑物防雷滚球半径可以参考使用75 m。

The article proposed that importance shall be attached to lightning protection of rural houses on the basis of analysis made upon characteristics of rural houses and causes of their vulnerability to lightning strike; it derived rational values of rolling sphere radius for lightning protection design of rural houses; and proposed that a 75m rolling sphere radius may be adopted for lightning protection design of small mass buildings within the latitude of 45 degree.
