电涌保护器的选择及使用中应注意的问题

摘要

The correct selection and installation of surge protection device(SPD) is the key to protect electronic equipments and is the most important aspect of the lighting protection engineering. If the selection and installation of SPD is not correct, equipments will be damaged. This paper focuses on introducing the basis of selecting multiple SPD and the problems which shall be noticed when the SPD is installed in the view of how to protect electronic system from lighting electromagnetic impulse.%　　正确选择和使用电涌保护器(SPD)是保护电子设备的关键,SPD的选择及安装是防雷工程最重要的环节,如不能正确选择和安装电涌保护器就不可能起到保护设备的功能,甚至还会出现损坏设备的事故。从对电子设备进行雷击电磁脉冲防护的角度,重点阐述了安装多级SPD的依据以及在使用过程中应注意的事项。
