摘　　要：建筑物的接地系统在保障人身安全、防止设备损坏、减少电磁干扰以及防雷保护等方面起到重要作用。根据现行规范《建筑物防雷设计规范》GB 50057—2010和《建筑电气与智能化通用规范》GB 55024—2022,接地装置材料应考虑电化学反应,本文通过电化学腐蚀的严重程度分析计算,得出结论:一般情况下使用镀锌钢材做接地装置不会影响接地效果。The earthing system of buildings plays a crucial role in ensuring personal safety,preventing equipment damage,reducing electromagnetic interference,and providing protection against lightning.According to the current standards outlined in the“Code for Design Protection of Structures Against Lightning”(GB 50057-2010)and the“General Code for Building Electricity and Intelligence”(GB 55024-2022),the materials used for grounding devices should take electrochemical reactions into consideration.Through the analysis and calculation of the severity of electrochemical corrosion,this paper concludes that,under normal circumstances,using galvanized steel as a grounding device does not affect the effectiveness of the earthing system.
