论山顶炸药贮存库的外部防雷

Exterior Lightning Protection of Detonator Storeroom on Mountaintop

山顶炸药贮存库因其所处的自然环境,受雷击的可能性较大。针对炸药库自身特点以及山顶环境,选择了适合的避雷方式,并对炸药库年预计雷击次数作了计算。介绍了炸药贮存库的防雷级别,详细分析了接闪器和接地体的布置。最后介绍了防雷接地电阻检测仪的使用。

As natural environment of the detonator storeroom on mountaintop, the detonator storeroom is more easily stroken by lightning. According to its features and the environment of the mountaintop, the proper lightning protection mode was selected, and the prediction number of annual lightning strikes to detonator storeroom were eaeulated. The lightning protection class of detonator storeroom was introduced, and the collocation of flash-grounding device and grounding device; were analyzed in detail. At last, the use of lightning protection grounding resistanee monitoring was introduced.
