外部防雷系统在建筑物防雷措施中的应用研究

Research on Application of External Lightning Protection System in Lightning Protection Measures for Buildings

在对国内建筑物接地和外部防雷系统的现状研究中发现,浪涌保护器的应用占比远大于外部防雷系统的投入。通过对外部防雷系统在建筑物防雷措施中的应用研究,基于CDEGS仿真模型,对比构件试验样品在使用专用贯通夹具固定和使用绑扎法固定情况下,接受不同模拟仿真雷电流雷击试验后的仿真数据,得出相关结论,从而确定不同连接工艺在外部防雷系统中对基础构件的影响。

By analyzing research status of domestic buildings′earthing and external lightning protection,there has been found that surge protective devices account for a much larger proportion of total cost in external lightning protection system.Based on CDEGS simulation model,this paper studies the application of external lightning protection system in lightning protection measures for buildings,compares test specimens whose the components with appropriate connector and with wire,gathers the data after lightning test by different simulation lightning currents acting on component.Then it draws relevant conclusions,and consequently determines the influences of different connection processes on basic components of external lightning protection system.
