摘要
在城市轨道交通的低压配电设计中,风机启动时的电压暂降不仅关系着供电系统能否合理安全地运行,也关系着在发生火灾时,设备能否正常启动运行,因此,大功率和长距离配电电动机启动电压暂降的计算是设计中重要的一部分。论文以南京地铁某站为例,对活塞风机的启动电压暂降进行计算校验和理论研究,提供相关参考。
In the low-voltage distribution design of urban rail transit,the voltage sag when the fan starts is not only related to the reasonable and safe operation of the power supply system,but also related to the normal start-up and operation of the equipment in case of fire.Therefore,the calculation of the start-up voltage sag of high-power and long-distance distribution motor is an important part of the design.Taking a station of Nanjing Metro as an example,this paper studies the calculation and theory of the start-up voltage sag of the piston fan,and provides relevant reference.
