摘　　要：建筑物内低压电源系统电涌保护器(SPD)设计和安装等依据的技术规范为GB 50057-2010和GB 50343-2012。由于两个规范对SPD的相关规定存在较大差异,导致防雷工作中SPD设计、安装等标准无法统一。从SPD术语、安装位置、放电电流、级别设置相关条款进行对比分析,发现:1SPD术语仅翻译不同。2GB 50343对SPD安装位置要求较准确;GB 50057关于SPD放电电流的规定更合理。3SPD级别设置的计算方法不同。GB 50057--2010 and GB 50343--2012 are the main standards about the design and installation of coordinated SPDs protection for the electrical systems within structures, but there are big differences between the two standards about the SPD. An analysis current and coordination of SPDs. The results show： is made of the definition, location, discharge （1） The explanations of SPD definitions are different, but the physical meanings are accurate in GB 50343, and the regulations （3）The calculation methods of SPD levels consistent. （2） The requirements of SPD location are more about the discharge current of SPD in GB 50057 are reasonable. are different in GB 50057 and GB 50343.
