摘　　要：依据标准GB 50057—2010和IEC 62305:2010系列规范,比较了建筑物防雷设计中滚球法、网格法、保护角法的保护原理和适用范围,分析了建筑物屋面接闪器的布置原则。对于一般性民用建筑物屋面,当接闪器满足滚球法对屋面平台的保护时,屋面可不再采用网格法额外设置接闪网格的设计方式。According to the standard GB 50057—2010 and IEC 62305:2010,the protection principles and application scope of the rolling sphere method,the mesh method and the protection angle method in lightning protection design of buildings were compared.The positioning principle of roof air-termination system arrangement of buildings was analyzed.For the general civil building roof,when the air-termination system meets the protection of the rolling sphere method to the roof platform,the roof can no longer use the mesh method to design.
