电网电压暂降对用电客户的影响及对策

Influences and Countermeasures of Grid Voltage Sags on Power Custome

随着现代企业电子设备的大量应用,电子元器件对电压暂降的敏感不尽相同,部分元器件常因电压暂降而停止工作,导致整套设备受到影响。针对电网电压暂降引起用户内部设备欠压保护动作导致设备停电,分析了发生电压暂降的原因及危害,并结合案例提出了改进建议。

With the large number of applications of electronic equipment in modern enterprise, the responses of grid voltage sag of different electronic components are different. Part of the components may stop work due to voltage sags, which may leads to the whole equipment affected. For the low-voltage protection of internal equipment action caused by voltage sags, the cause and damage of grid voltage sags are analyzed. Besides, suggestions are proposed to improve such cases.
