低压配电系统电涌保护器的选型

Selection of Surge Protective Device in Low Voltage Power Distribution System

介绍在设备电源线路上低压配电系统电涌保护器(SPD)的选型和安装时应注意的问题。通过SPD泄放雷电涌能量和降低过压幅度并辅以适当措施,以减少低压电气设备和电子信息系统受雷电涌的危害,降低人员和财产的损失。

The items that should be considered when selecting and installing surge protective device （SPD） of the low voltage power distribution system was introduced. In order to protect low voltage electrical equipment and electronic information systems from lightning and reduce personnel and property damage, the lightning surge energy was bled and the overvoltage was reduced through the SPD with approptiate mesaures.
