摘　　要：以京广高铁郑州东枢纽牵引变电所为例,分析了存在的风险以及提高枢纽牵引变电所可靠性的对策,重点研究了枢纽牵引变电所的独立备用供电单元、备用母线、备用馈线开关柜、供电线缆、新增生产房屋等实施方案,在此基础上提出了既有枢纽牵引变电所备用方案,对提高牵引供电系统的可靠性具有一定参考意义。Taking the traction substation for Zhengzhou East Hub as an example,the paper analyzes the existing risks and the counter measures for improving the reliability of the hub traction substation,focuses on the studies on the implementation schemes for the independent backup power supply units,backup bus bars,backup feeder switch cabinets,feeder cables and added production buildings,and on the basis of these,puts forward the backup schemes for the existing hub traction substation.It has certain values of reference for improving of traction power supply system relaibility.
