摘　　要：弓网系统是高速列车获取持续动力的唯一途径,其动态受流性能直接决定列车能否高速稳定运行,目前国内外尚无可供借鉴的400 km/h接触网技术标准及工程案例。本文基于400 km/h接触网服役环境、接口条件以及性能提升的需求,全面比较了400 km/h接触网系统与现有350 km/h接触网系统的差异,深入分析了400 km/h速度下弓网系统面临的关键技术问题,针对性地提出了应对解决措施,并从基础理论、设计技术、装备制造、施工建造、运营维护及规范标准等方面形成了400 km/h接触网技术体系框架,全面推进CR450科技创新工程的实施。The pantograph-catenary system is the only way to receive continuous power supply for high speed trains,and the dynamic current-receiving performance directly determines whether the trains can run stably at a high speed.At present,there are no technical standards and engineering cases of 400 km/h overhead contact system for reference at home and abroad.Based on the service environment,interface conditions and performance improvement requirements of 400 km/h overhead contact system,this paper compares and analyzes the differences between 400 km/h overhead contact system and the existing 350 km/h overhead contact system,makes an in-depth analysis on the key technical issues encountered by the pantograph-catenary system at 400 km/h,and puts forward the solutions,forming a 400 km/h overhead contact system technical system framework from the aspects of the basic theory,design technology,equipment manufacturing,construction,operation and maintenance,and code and standard,to comprehensively promote the implementation of CR450 technical innovation project.
