重庆As型地铁车辆受电弓技术

Pantograph Technology for Chongqing As Metro Vehicles

As型地铁列车是适应山地城市地形地貌特点开发研制的新型地铁列车,它具有爬坡能力大、曲线半径小、运维成本低等诸多优点。正线隧道内采用刚性接触网,牵引功率较一般地铁列车大,为了改善受流条件而设计4台受电弓并联受电的形式。文中就As型地铁列车受电弓的基本结构、日常运维等方面进行介绍,特别是对碳滑板的使用寿命进行分析,阐明了当前As型地铁列车在受电弓系统运用效果,值得借鉴与推广。

As metro train is a new type of metro train developed to adapt to the mountain city’s landform and physiognomy.It was first used in the second round of construction in Chongqing.As Metro train has many advantages,such as large climbing capacity,small curve radius,low operation cost and so on.In order to improve the condition of receiving current,four sets of pantographs are designed to receive electricity in parallel.This paper introduces the basic structure and daily operation and maintenance of As type train pantograph,especially analyzes the service life of carbon slide plate,and expounds the application effect of As type subway train in pantograph system at present,it is worth learning and popularizing.
