摘　　要：为了更好地执行GB 55024—2022《建筑电气与智能化通用规范》,确保建筑电气安全,论文对GB 55024—2022《建筑电气与智能化通用规范》第7.1节雷电防护中部分条文和GB 50057—2010《建筑物防雷设计规范》进行了比较和分析。并结合IEC标准相关内容,对建筑物的防雷分级、接闪网格法的应用、建筑物进线电源处SPD的选择等问题进行了研究。研究结果显示,GB 55024—2022《建筑电气与智能化通用规范》与其他规范在雷电防护上内容有较大变化,并且GB 55024—2022《建筑电气与智能化通用规范》是根据IEC相关标准进行的修订。该规范的部分条文应当结合对应的强制性工程建设项目规范进行使用。In order to better implement GB 55024—2022 General Code for Building Electrical and Intelligentization and ensure electrical safety of buildings,a comparison and analysis were conducted on some provisions in Section 7.1 of GB 55024—2022 General Code for Electrical and Intelligent Building Protection and GB 50057—2010 Design Code for Lightning Protection of Buildings.And combined with the relevant content of IEC standards,research was conducted on the lightning protection classification of buildings,the application of lightning grid method,and the selection of SPD at the incoming power supply of buildings.The research results show that there are significant changes in the content of lightning protection between GB 55024—2022 General Specification for Building Electrical and Intelligence and other specifications,and GB 55024—2022 General Specification for Building Electrical and Intelligence is revised based on relevant IEC standards.Some provisions of this specification should be used in conjunction with the corresponding mandatory engineering construction project specifications.
