摘　　要：成渝中线综合试验段作为CR450科技创新工程的示范应用线路,将开行CR450新型动车组。CR450动车组功率的提升对牵引供电系统供电能力提出了更高要求,因此《成渝中线高速铁路设计暂行规范》提出“条件允许时可采用双边供电方式”。本文分析了牵引供电系统双边供电方式下牵引网3种接线方案及运行方式,对比优缺点,明确了成渝中线双边供电牵引网接线方案,并就不同接线方案工程适应性提出建议。As a demonstration application line for the CR450 technology innovation project,the Second Chengdu-Chongqing High-speed Railway will operate the CR450 new high-speed trains.The increase in power of CR450 high-speed trains has put forward higher requirements for the power supply capacity of the traction power supply system.Therefore,the Interim Design Specification for the Second Chengdu-Chongqing High-speed Railway proposes that"bilateral power supply can be used when conditions permit".The paper analyzes three wiring schemes and operation modes of the traction network under the bilateral power supply mode of the traction power supply system,compares their advantages and disadvantages,clarifies the wiring schemes of the bilateral power supply traction network for the Second Chengdu-Chongqing High-speed Railway,and puts forward suggestions on the engineering adaptability of different wiring schemes.
