现代有轨电车无接触网技术应用分析

Analysis of Catenary-free Technology Applied in Modern Trams

无接触网技术在现代有轨电车的应用,解决了有轨电车接触网造成的"视觉污染"问题。介绍了采用地面供电技术的APS(交替式地面)系统、Tramwave(创威地面感应式)系统和Primove(电磁感应式)系统,以及各种车载储能技术。分析比较了不同无接触网技术的系统设计、性能和长期运营维护情况。车载储能技术作为一种广泛应用的工业技术,在达到小型化、高能量比、快速充放电和环保处理方式后,将成为现代有轨电车无接触网技术的发展方向。

Catenary-free technology has been used in modern trams,which solves the ＂visual pollution＂ due to the contact system and is adopted by many cities.The ground level power supply systems like APS,Tramwave and Primove,as well as the on-board energy storage technology are introduced,which provide different solutions for trams power supply.Through an analysis and comparison of the design,operation and long-term maintenance of different catenary-free technology systems,the on-board energy storage technology is considered to be the development trend for modern trams when it solves problems like miniaturization,high energy quatity,rapid charge and discharge speed,as well as the green recycle mode.
