地铁动力配电系统的设计研究

Design Research of Metro Power Distribution System

文章以广州地铁某车站为例,提出了动力配电的设计要点,地铁车站的动力配电是对车站的风机、水泵、电扶梯、综合监控、通信、信号、火灾自动报警系统、屏蔽门等动力设备的配电、控制设计及相关专业的接口设计,还包括从降压变电所向车站两端区间的动力配电设计和接地设计。

This paper takes a station in Guangzhou Metro as an example,and puts forward the key points of power distribution design.The power distribution of subway stations is the distribution and control design and related professional interface design of power equipment such as fans,water pumps,escalators,comprehensive monitoring,communication,signals,automatic fire alarm systems,and screen doors in the station.It also includes the power distribution and grounding design from the step-down substation to the metro sections at both ends of the station.
