摘要
Abstract
Based on the lightning survey data of Sanshui in Guangdong province, and the lightning test of communication buildings. Seven aspects of High-rise buildings lightning protection as attractive radius, shielding effect, shielding angle, frame resistance, radiation resistance, metastasis potential and the grounding system were discussed. It shows that if the high-rise buildings is with large attractive radius, the flash device is suggested for vertical lightning rod attracting upwards lightning. If the high- rise buildings are with small shielding angle, the adjacent buildings are also suggested to take the necessary measures for lightning protection. The impedance of Steel frame and radiation can not be ignored. The characteristics of frequency coupling, electrical coupling and high coupling should be considered while the metal pipelines are laid along the height. The transfer potential generated by Metal pipelines will transfer to neighboring buildings through introducing the leading-out the metal pipe. The grounding system was composed by the grounding forms with different use.关键词
