摘要
国内地铁工程联络线接触网供电分段设计普遍采用单分段绝缘器和轨道绝缘结的方案,存在故障紧急抢修安全隐患和跨线调车作业效率低下的情况。本文从供电分区、运营维护及调度作业等具体实际情况出发,优化了地铁工程联络线接触网的供电分段方案,可以大大提高供电运行的灵活性和可靠性,实现地铁在有限的天窗点内快速安全恢复故障和高效的车辆跨线调度作业。
The scheme of single section insulator and track insulation junction is widely used in the design of catenary power supply section of the interconnection line in domestic metro projects,which has potential safety hazards for emergency repair and low efficiency of cross-line shunting operation.Starting from the actual situation of power supply zoning,operation and maintenance,and dispatching operation,this paper optimizes the power supply section of the contact network of the metro engineering liaison line,which can greatly improve the flexibility and reliability of power supply operation,and realize the rapid and safe recovery of faults in the limited skylight points of the metro and efficient vehicle cross-line dispatching operation.
