文物古建筑雷电防护关键技术研究

Research on key Technology of lightning protection of cultural relics and ancient buildings

以泰宁县某全国重点文物保护单位的古建筑为例,分析其所处区域的雷电活动规律及其影响,针对部分文物古建筑在防雷工程设计中存在的普遍性问题,提出做好防护“直击雷”“闪电电涌侵入”“闪电感应”与“接触电压与跨步电压”等关键雷电防护技术措施,并提出在雷电环境恶劣之处安装“独立接闪装置”等特殊防护措施,建立完善的雷电防护系统,以确实增强文物古建筑的雷电防护能力,避免或减少雷击安全隐患,落实文物古建筑保护单位的雷电防护安全工作。

This article takes the ancient buildings of a national key cultural relics protection unit in Taining County as an example,analyzes the law of lightning activity in the area and its impact,and proposes to protect some cultural relics and ancient buildings in the common problems in the design of lightning protection projects."Direct lightning strikes","lightning surge intrusion","lightning induction"and"contact voltage and step voltage"and other key lightning protection technical measures,and proposed to install"independent lightning protection devices"and other special protections in places with harsh lightning environments Measures to establish a complete lightning protection system,indeed enhance the lightning protection capabilities of cultural relics and ancient buildings,avoid or reduce the safety hazards of lightning strikes,in order to provide technical reference for the lightning protection safety work of cultural relics and ancient buildings.
