摘要
首先对雷电保护区进行了划分,并分析了雷击铁塔时,雷电引入民房的渠道,包括电磁感应和地电位反击2个方面。计算分析了空间磁场和地电位反击对附近居民的影响,并提出了对附近居民电器设备和人身安全的防护措施。
It first classifies the lightning protection zones, and then analyzes the paths through which the lightning current is led to the res-idence when the tower is struck by lightning, including electromagnetic induction and earth potential counterattact. Final y, it proposes several protection measures to protect adjacent household appliances and persons based on calculation and analysis of effect caused by spatial magnetic field and earth potential counterattact on the nearby residents.
