高速铁路轨回流通道施工技术研究

以武广客运专线高速铁路重联编组运行为背景,针对动态试验（联调联试）中接触网和信号工程接口部分出现的问题,分析了牵引供电轨回流通道中信号扼流变压器、接触网吸上线、接触网至变电所回流电缆方面的工程技术应用,针对动车高速运行中牵引电流和动力缺失的影响,提出了工程设计施工方面的建议,供今后高速铁路建设参考。

Study on Construction Technology for Rail Return Current Channels for High Speed Railways

With a background that double heading operation mode is adopted for Wuhan-Guangzhou high speed passenger dedicated line,and on basis of the problems occurred in interfacing between overhead contact system and signal system during dynamic acceptance (general commissioning and testing),analyzes the application of engineering technologies at traction power supply rail return channels e.g. signal choke transformer,boosting wires of overhead contact line,the current return cables between overhead contact line an...
