风景名胜区雷电防护讨论

国家级重点风景名胜区一般都有遭到雷击的现象,雷击可使数十米高的大树被劈断、震碎或烧焦。当雷击树木（山体）游客巧在现场之际可能发生＂跨步电压＂电击事故,严重时将导致游客伤亡。该研究通过计算雷击引起行人＂跨步电压＂的量值和人体可承受工频电流、雷击电流与电压量级,并对风景名胜区设计避（引）雷针如何减弱＂跨步电压＂方法进行了讨论。期望对今后风景区防雷设置的人性化提供依据。

Discussion on the Lightning Protection of Scenic Spots

National-level key scenic spots struck by lightning are commonly happened,high dozens meters of tree cut down,shattered or burnt by lightning. The lightning struck the trees (mountain) at the scene tourists may lead to "step voltage" electric shock accident,which involving serious injuries of tourists. The "step voltage" quantity value,human body can withstand power frequency currents,lightning current and voltage magnitude level were calculated; Lightning protection install of the scenic spots to people-or...
