摘　　要：主要针对九景衢客专开通前的短路试验,根据现场数据比较电抗法测距与上下行电流比测距两种测距的优劣,提出了将上下行电流比测距与电抗法测距相结合应用于直接供电牵引网测距的措施。According to the short-circuit test before the opening of passenger dedicated line of Quzhou-Jiujiang Railway, this paper compares the advantages and disadvantages of reactance distance measurement and up-down current ratio distance measurement according to the field data, and puts forward the measures of combining up-down current ratio distance measurement and reactance distance measurement in direct power supply traction network distance measurement.

关 键 词：测距 电抗法 上下行电流比
