摘要
电气化铁路牵引变电所故障测距的准确性对牵引供电馈线接触网故障查找起着极其重要的作用。本文结合实际运行经验,介绍提高“直供+回流”供电方式下电抗法和上下行电流比法故障测距准确度的方法,分析了现阶段故障测距的不足,并提出了相关应对措施,对指导供电工区快速准确定位故障起到积极作用。
The accurate fault location of traction substation of electrified railway plays an important role in trouble shooting of traction power supply feeders and OCS.With connection to the practical operation experience,the paper introduces the fault location by means of reactance method and upward/downward current ratio method,analyzes the disadvantages of the currently applied fault location methods and puts forward the related counter measures,playing a positive role foe rapid fault location for power supply section.
