城轨接触网供电分区失电故障下的行车交路设计

Design of traffic routes under the failure of catenary power supply partition in subway

接触网供电分区失电故障会导致城市轨道交通线路运营中断,造成一定的负面影响。通常发生接触网供电分区失电故障时,在明确故障原因及现场实际情况后,遵循“先通后复”的原则优先采取变更行车交路的方法进行运营调整。文章以南京地铁2号线2A7及2B7供电分区失电故障为例,设计行车交路以最大限度降低故障造成的延误,并将调度处置的关键点进行归纳,为地铁安全、有序、高效地运营提供一定的参考建议。

The failure of catenary power supply partition will lead to interrupt the operation of the subway transit lines and cause certain negative impact.Usually,when the power loss fault occurs in the catenary supply partition,after clarifying the cause of the failure and the on-site situation,will follow the principle of“the first pass through and then return”,the method of changing traffic routes shall be prioritized for operation adjustment.This paper takes the failure of the 2A7 and 2B7 power supply partition in Nanjing Metro Line 2 as an example,designs the traffic route to minimize the delay impact of the fault,and the key points of dispatching and disposal are summarized,so as to provide certain reference suggestions for the safe,orderly and efficient operation of the subway.
