摘要
目前随着我国经济快速发展,货物运输体量逐渐庞大,对重载铁路的依赖不断加深。我国以神朔铁路、大秦铁路为代表的重载铁路,不仅运输能力强,还实现绿色、安全的生产运输,得到国家相关部门的充分认可。为了挖掘朔黄铁路其运输潜力,本次进行朔黄铁路3万吨重载试验列车供电系统研究。列车重载意味着牵引功率高、牵引电流大,极易引起接触网及整个供电系统电压的波动。因此,本此对3万吨重载列车运行时对牵引供电系统的影响进行研究,分析其可能造成的问题,并给出其解决方案。通过本课题的研究,发现朔黄铁路3万吨重载列车对目前牵引供电系统运营安全带来的隐患,从而有针对性的研究解决措施,为3万吨重载列车的开行提供有力的支持。
At present,with the rapid development of China's economy,the volume of freight transportation is gradually increasing,and the dependence on heavy-duty railways is deepening.China's heavy-duty railways,represented by the Shenshuo Railway and Daqin Railway,not only have strong transportation capacity,but also achieve green and safe production transportation,which has been fully recognized by relevant national departments.In order to tap into the transportation potential of the Shuohuang Railway,a study was conducted on the power supply system of the 30000 ton heavy load test train on the Shuohuang Railway.Heavy loading of trains means high traction power and high traction current,which can easily cause voltage fluctuations in the contact network and the entire power supply system.Therefore,this study investigates the impact of the operation of a 30000 ton heavy-duty train on the traction power supply system,analyzes the possible problems it may cause,and provides solutions.Through the research of this topic,it has been discovered that the 30000 ton heavy-duty trains on the Shuohuang Railway pose hidden dangers to the operational safety of the current traction power supply system.Targeted research and solutions have been developed to provide strong support for the operation of the 30000 ton heavy-duty trains.
