延长电客车正线动态调试周期的可行性分析

Feasibility Analysis on Prolonging the Dynamic Commissioning Period of the Main Line of Electric Passenger Train

郑州地铁各线路检修规程均要求对电客车进行年检动态调试(以下简称动调),5号线中州大道车辆段因试车线封闭停用,年检动调选择在正线及库内进行,其他线路在段场配属的试车线进行。5号线首次年检动调以来累计开展了46列次作业,没有发现故障,综合评估后建议延长部分动调项目的检查周期。

The maintenance regulations of all lines of Zhengzhou metro require annual inspection and dynamic adjustment of electric passenger cars.The Zhongzhou Avenue depot of line 5 is closed and out of service due to the closure of the testing line.The annual inspection and dynamic adjustment shall be carried out in the main line and depot,and other lines shall be carried out on the testing line allocated to the depot.Since the first annual inspection and dynamic commissioning of line 5,46 trains have been carried out in total,and 0 faults have been found.After comprehensive evaluation,it is suggested to extend the inspection cycle of some dynamic commissioning projects.
