随着城市轨道交通建设的快速发展,国内轨道交通直流牵引系统中为了最大限度的保护人员的安全,在钢轨与大地间装配了轨电位限制装置。轨电位限制装置是目前城市轨道列车牵引运行中的一个关键技术,它关系到牵引供电系统的运行安全、乘客和工作人员的安全。目前,广州地铁各条线的车站变电所均有安装了轨电位限制装置。重点介绍广州地铁五号线轨电位限制装置的结构、工作原理、保护设置、轨电位产生的原因和防止措施,及在日常中的运用,并针对在实际运用中出现的一些问题进行分析、总结,并提出合理化建议。
With the rapid development of urban rail transit construction, in order to maximize the safety of personnel in the domestic rail transit DC traction system, a rail potential limiting device is installed between the rail and the earth. Rail potential limiting device is currently a key technology in the traction operation of urban rail transit trains, which is related to the safe operation of the traction power supply system, the safety of passengers and staff. At present, all stations in Guangzhou Metro substation have installed rail potential limiting device. The structure, working principle, protection setting, causes and preventive measures of rail potential and its application in daily life are mainly introduced. The problems that arise in practical application are analyzed and summarized. , And put forward reasonable suggestions.
