摘　　要：对可能涉及直流牵引网运行方式转换的故障类型进行分类,详细分析传统的牵引网越区供电方案在运行方式转换时对线路正常运营及调度管理的不利影响。通过改变越区开关的设备选型方案,提出新型的转换方案,对其在工程实际中的运营调度方案及对直流牵引供电系统后期运营维护管理模式的影响进行分析说明。对牵引网上网开关及越区开关的设置位置的不同选择方案进行详细分析,从以人为本和工程长期运营的可维护性方面,提出将其从线路区间调整至车站室内布置的优化方案。This paper organizes the fault types that may involve DC traction network operation mode conversion and analyzes in detail the adverse effect of a traditional traction network cross-district power supply scheme on the traditional operation and dispatching management of the line during operation mode conversion. By changing the equipment selection scheme of the cross-district switch, this paper proposes adopting a new type of traction network and analyzes the operation scheduling scheme in the actual project and its influence on the later operation and maintenance management mode of the DC traction power supply system. Based on a detailed analysis of the location selection scheme of the district switch, this paper proposes a specific optimization scheme based on the maintainability of the long-term operation of rail transit projects.
