摘要
介绍电源系统干扰的概念、干扰类型、干扰特性,尤其是雷击电涌和操作过电压干扰;分析电涌保护器(SPD)对电源系统干扰的响应情况;指出应利用SPD对电源系统干扰的响应以提供对设备的保护。
The concept of power supply system interference and thetypeand characteristicsof interference are introduced,especially lightning strike surge and switching overvoltage interference;the response of surge protective device(SPD)to power supply system interference is analyzed;it points out that the response of SPD on power supply system interference shall be used to provide protection for equipment.
