地铁设计中低压配电箱的选型研究

Study on Selection of Low Voltage Distribution Box in Metro Design

城市轨道交通供配电系统是城市轨道交通安全运行的保障,低压配电箱是供配电系统的重要组成部分。文中以城市轨道交通工程机电产品选型为切入点,重点分析了低压配电箱选型中应关注的电气参数、主要元器件及箱体结构工艺等问题,希望对城市轨道交通的低压配电箱选型有所帮助。

The power supply and distribution system of urban rail transit is the guarantee of the safe operation of urban rail transit,and the low-voltage distribution box is an important part of the power supply and distribution system.Starting from the actual needs of urban rail transit project,this paper focuses on the analysis of the electrical parameters,main components and box structure and technology that should be paid attention to in the selection of low-voltage distribution boxes for urban rail transit,hoping to be helpful to the selection of low-voltage distribution boxes for urban rail transit.
