轻轨交通轨道特点与设备发展研究——轻轨之器

Research on Track and Sustain Electromechanical Equipment of Light Rail Transit——the Equipment of LRT

从轻轨与地铁、有轨电车对比的角度,阐述轻轨系统的轨道、供电、弱电等系统的特点和研究重点,进一步完善轻轨系统合理的功能定位和技术发展目标。在走行系统方面,轻轨包括钢轮钢轨和橡胶轮胎两类,需要根据不同轮轨特征进行轨道设计;在供电系统方面,除了遵循当前设计规范外,在做好轻轨系统的外部电源规划的基础上,建议针对轻轨特点研究确定供电配置标准和负荷等级;在弱电系统方面,结合当前新技术发展,提出综合化、智慧化趋势;最后从提高乘客服务水平与环保节能效能角度,提出电扶梯、通风空调等的配置要求,以提高轻轨交通的出行吸引力。

The paper expounds the characteristics and research focus of the track,power supply system and weak current system of light rail transit(LRT)based on comparisons between light rail,subway and tram systems.The function of LRT and its technological development goal are defined.The running system of LRT uses steel wheel rails and rubber tires,and the track should be designed in line with different characteristics of the rails.For the power supply system of LRT,in addition to following the current design specifications,external power supply planning is needed the power supply configuration standard and load level are to be decided with the characteristics of LRT tracks taking into account.An integrated and intelligent development trend for the weak current system is analyzed in terms of the current development of new technologies.Finally,to attract new riders of LRT,the requirements of setting up escalators,ventilation and air conditioning systems are put forward from the perspective of improving passenger service level and environmental protection and energy saving efficiency.
