简述我国建筑物防雷的历史,着重说明设计和研究建筑物防雷应从雷击规律入手,并总结和分析了北京地区的雷击规律。说明了建筑物防雷设计应当掌握的重点,即(1)外部防雷装置和内部防雷装置;(2)安全隔离距离和等电位联结;(3)雷电电磁脉冲的防护;(4)球雷的防护;(5)建筑物防雷设计的整体观念——其中适当在大树上安装避雷针,可作为整体考虑。 The history of building lightning protection in China is briefly described. It is emphatically stated that the design and research of building lightning protection should start from the lightning strike laws, and summarizes and analyzes the lightning strike laws in Beijing. Explained the key points that a building’s lightning protection design should master, namely: (1) external lightning protection devices and internal lightning protection devices; (2) safety isolation distance and equipotential bonding; (3) lightning electromagnetic pulse protection; (4) ball The protection of mines; (5) The overall concept of lightning protection design of buildings - where appropriate installation of lightning rods on large trees, can be considered as a whole.
