柔性接触网线岔电连接线安装工艺优化方案探讨

Optimization of Installation Process for Crossover Electrical Connection Line of Flexible Catenary

线岔是城市轨道交通供电系统接触网系统的重要设备之一。为了确保股道之间接触网电路的畅通,必须在线岔处设置电连接线。介绍、分析了近年来上海轨道交通柔性接触网线岔电连接线发生的几起故障,提出了线岔电连接线安装工艺的优化方案、确保弓网配合安全可靠。有关经验供类似工程参考。

Crossover is one of the important equipment of catenary system in urban rail transit power supply system.In order to ensure the smooth operation of catenary circuit between tracks,it is necessary to set up electric connection line at the crossver.Several failures of the electrical connection line of the flexible catenary in Shanghai rail transit in recent years are introduced.And the optimization scheme for the installation process of crossover electrical connection line are proposed so as to ensure the safety and reliability of the pantograph and catenary,which can be referred for similar projects.
