摘　　要：本文以某科研实验用房改造项目为例,针对既有建筑防雷与接地系统改造的技术难点,提出了一种经济性与美观性并重的解决方案。通过分析现行电气设计规范要求与项目实际情况,着重对防雷接闪带、防雷引下线、基础接地极等方面进行了电气化设计,进而完成本项目完整的防雷接地系统构建,这为类似项目提供了重要的理论与实践参考。In this paper,we take a restruction project for a scientific research laboratory as an example to investigate the difficult issues for the design of lightning protection and grounding system and further propose a solution with consideration of economy and aesthetic.By combining the current norms of electrical design and the practical situations of this project,this paper focuses on the electrical design in the aspects of lightning rods,down conductors,and foundation grounding electrodes,leading to the construction of the lightning protection and grounding scheme,which is significant in theory and practical application for other projects.
