大秦铁路接触网故障测距失效案例分析及改进方案探讨

Analysis of Cases of Failure of Fault Location of OCS of Datong-Qinhuangdao Railway and Exploration on Schemes for Its Improvement

大秦铁路列车运行密度大,牵引负荷重,牵引供电系统运行的可靠性对保障线路正常运输具有重要意义,最大程度缩短供电故障延时,保证供电畅通非常关键。本文通过对大秦铁路牵引供电接触网故障测距失效造成故障查找处理延时长的案例进行分析,探讨在测距失效情况下的应急辅助措施,通过人工核算确定故障范围,缩短故障处理时间。通过实践验证,在正常测距失效情况下采取人工计算故障距离的辅助措施,能快速定位故障点,有效缩短故障处置时间。

Datong-Qinhuangdao railway is high in its operation density of trains and is heavy in its traction load,the reliability of its traction power supply system is of great significance for ensuring the normal transportation of the line.It is crucial to minimize the delay of power supply faults and ensure smooth power supply.The paper analyzes the case of a long time delay in trouble shooting and handling due to the failure of fault location for the OCS of traction power supply system of Datong-Qinhuangdao railway,explores the emergency and assistance measures in case of failure of fault location,determining the scope of fault by manual calculation and shortening the time for disposal of faults.Through practical verification,adopting manual calculation of fault distance as an assistant measure in case of failure of normal fault location can quickly locate the fault point and effectively shorten the time for handling of fault.
