智能建筑物供配电系统中电涌保护器的配置

The configuration of surge protection device of power supply system in intelligent buildings

电涌是由雷电、电源切换及大型设备开、关操作导致的瞬态过电压,可造成敏感电气设备的一次性损坏和提前老化。通过对低压配电系统接地方式的介绍及电涌对电子系统设备的潜在危害性分析,在智能建筑物供电电源系统设计中应结合相应接地系统对电涌保护器进行配置。

Surge is by lightning, power switching load and some other large equipment, leading to transient overvoltage,can cause sensitive electrical equipment of one-time damage, disorder and premature aging. In this paper, the grounding of the low-voltage distribution system type, as well as the introduction to the surge of expensive electrical equipment potential hazards of analysis, in electrical engineering design should be combined with the corresponding grounding system, of SPDs in intelligent building power supply system configuration.
