城市轨道交通直流牵引供电系统接触网残压

Residual Voltage of Catenary in DC Traction Power Supply System of Urban Rail Transit

对于城市轨道交通来讲,在运行的过程中,直流牵引供电系统是使用最为主要的部件之一。在该系统应用的过程中,接触网残压问题是较为严重的问题,也是当前所出现问题当中比较普遍的一种。对于直流牵引供电系统来讲,当出现接触网残压问题时,可能会对人的生命安全造成严重威胁,同时也会使检修施工和接触网送电保护闭锁等相关工作受到影响,严重拖慢工作进度。因此,论文通过测试、仿真分析和模拟验证等方法,对城市轨道交通直流牵引供电系统接触网残压问题进行了研究与论述。

For urban rail transit,DC traction power supply system is one of the most important components in the process of operation.In the process of application of this system,the residual voltage of catenary is a serious problem,and it is also a common one among the current problems.For the DC traction power supply system,when the catenary's residual voltage problem occurs,it may pose a serious threat to people's life safety,and at the same time,it will also affect maintenance construction and catenary power transmission protection lockout and other related work,and seriously slow down the work progress.Therefore,through testing,simulation analysis and simulation verification and other methods,this paper studies and discusses the problem of residual voltage of catenary in DC traction power supply system of urban rail transit.
