摘要:
［目的］无冗余的刚性接触网在发生塌网后，须针对不同的塌网场景调整行车组织，尽量将事件影响和财产损失降至最低。［方法］发生接触网塌网事故后，可通过手葫芦吊起故障接触网或将故障接触网切除等，使得列车惰性通过故障点，进而提高行车效率。通过对不同接触网塌网故障场景进行分析，逐层递进地制定优化行车方案，并进行现场实战演练，收集数据进行对比分析，在确保安全的前提下，确定最终行车效率最高的方式。［结果及结论］在临时抢修后，基于故障具体场景，由现场专业技术人员判断，采用惰行通过、降升单弓通过及惰行越站通过等方式，维持线路运营状态，提高行车效率。通过优化行车组织、临时抢修后的行车组织调整及线网行车组织的调整与配合，大幅缩短了接触网塌网后的行车恢复时间，降低了该类故障对地铁正常运行的影响。
Abstracts:
［Objective］ In the event of a collapsed non-redundant rigid catenary, it is essential to adjust train operation organization according to different collapse scenarios, minimizing the impact of the incident and reducing property losses as much as possible. ［Method］ After the catenary collapse accident happens, by using methods such as manually hoisting the faulty catenary with a chain hoist or cutting off the faulty catenary, the train is allowed to pass the fault point in an inert state to improve train operation efficiency. Through the analysis of various catenary collapse fault scenarios, a progressive optimization scheme for train operation is formulated. Furthermore, on-site practical exercises are conducted, and data is collected for comparative analysis. Under the premises of ensuring safety, the optimal method for maximum train operation efficiency is determined. ［Result & Conclusion］ After temporary emergency repairs, based on the specific fault scenario, on-site technical experts should determine the use of methods such as inert passage, single pantograph height adjustment passage, and inert station-overtaking passage to maintain the line operational state and enhance the train operation efficiency. By optimizing train operation organization, adjusting train operation organization after temporary emergency repairs, and coordinating with the adjustment of line network train operation organization, the time taken to restore train operation after catenary collapse is significantly reduced, minimizing the impact of such incidents on metro normal operation.
