Analysis on Power SPD Configuration for Large- chassis Buildings Based on GB Standards

    Abstract:In accordance with the definition of earthing device as prescribed under Clause 5,Article 4. 3. 8,“Others”,“Separated Laying”and“the Structure”,Code for Design Protection of Structures against Lightning(GB 50057 - 2010),and in combination with drawings,the power SPD configuration for large-chassis buildings are analyzed;and it is pointed out that the structure fundation of large-chassis buildings is innately composed of a large area of“conjoined laying”concrete reinforcement. In terms of lightning protection and earthing system,there is no earthing device,which may be laid in the mode as discribed under the Clause“Others”or“Separated Laying”,between the buildings on“the Structure”as prescribted. This is the basis sufficient for the design of configuration of“coordinated SPD system”for large-chassis buildings.

    摘 要:围绕GB 50057 - 2010《建筑物防雷设计规范》第4. 3. 8条第5款的“其他”“独自敷设”和“本建筑物”赋予接地装置的界定文字,并结合图示展开大底盘建筑群电源SPD配置分析,指出:大底盘建筑群的结构基础先天是由“连体敷设”的一大片混凝土钢筋构成,就防雷接地系统而言,建造在其上的各栋建筑物之间,不存在互为“其他”“独自敷设”的接地装置,并且还是一栋所谓的“本建筑物”。据此配置大底盘建筑群“协调配合的SPD系统”设计依据足矣。
