Abstract：The national standard - Technical Code for Protection of Building Electronic Information System against Lightning(GB 50343 - 2012)was partially revised based on the standard project established in 2020. Overall framework of the technical contents in the revised standard is consistent with 2012 edtion of the Standard. The revised standard introduces ground flash density directly obtained by lightning location system,simplifies classification method of lightning protection level,supplements relevant technical requirements for such measures as isolation of surge on line,SPD external disconnectors,etc. With its up‑to‑data technology requirements and strong practicability,it can play an active role in guiding the design and construction of lightning protection of building electronic information system.

Key words：building electronic information system;protection against lightning;surge protective device (SPD);isolation of surge on line;SPD external disconnector;SPD intelligent monitoring device;ground flash density;lightning protection level

摘　要：国家标准《建筑物电子信息系统防雷技术规范》（GB 50343 - 2012）于2020年立项局部修订，修订后标准技术内容总体框架与2012版标准基本保持一致，修订后的标准引入了雷电定位系统直接获取的地闪密度，简化了雷电防护等级划分方法，补充了线路电涌隔离措施、SPD外部脱离器等相关技术要求，具有先进性、适用性和可操作性，可为规范和指导建筑物电子信息系统防雷设计和施工发挥积极作用。
