摘要
通过对持续运行电压、残压、通流容量、报警功能等具体参数的选择,阐述了在民用建筑电气设计中如何选择电涌保护器(SPD),从而保护系统持续稳定可靠运行。并从电压等级的选择、传输速率的选择、接口类型的选择等3个方面介绍了防雷器的选型,以期对电气设计人员选用SPD提供参考。
The ways to select SPD in electric design of civil building were expounded through the selection of continuous operating voltage,residual voltage,discharge current capacity and alarm function so as to guarantee the continuous,steady and reliable operation of system.The selection of lightning arrester was introduced from the three aspects like voltage grade selection,transmission rate selection and interface type selection.It would provide reference to electric designer when selecting SPD.
