The invention discloses a free neutral-section passing device for a train. The free neutral-section passing device is formed by connecting an electric neutral section of an overhead line system and a switching control compartment arranged on a line side through a high-voltage cable and an optical fiber. Integrated optical fiber sensor probes are mounted between a carrier cable and a contact line at a suspension point of the overhead line system, a contact line is lifted by a head bow of the train to acquire a bow position signal, the bow position signal required by the driving direction is input into a control system by setting the distance between the probes and assisting contacts by virtue of vacuum switches, and after the resistance value of a controllable rheostat is adjusted from zero to maximum, the program-controlled two vacuum switches supply power through the neutral overhead line system in a commutation mode, and the resistance value of the controllable rheostat is adjusted from the maximum value to zero after current limiting is finished. The device belongs to a department of the overhead line system, and the device operation is not associated with any department, so that standardized operation management is facilitated; an overhead line system department automatically solves the problem of free neutral section passing of the train, and a driver does not have a neutral section passing concept; and the device is low in cost, the electric split-phase structural form of the overhead line system and the construction cost are not changed, the application range is not limited, and application and popularization are facilitated.

    本发明公开了一种列车自由过分相装置,由接触网电分相与设在线路侧的换控厢经高压电缆和光纤连接组成。集成光纤传感器探头安装在接触网悬挂点处的承力索与接触线之间,利用列车首弓抬升接触线采集弓位信号,探头之间距离的设定并借助真空开关辅助触点,将行车方向需要的弓位信号输入控制系统,可控变阻器阻值从零调至最大后,程控两真空开关通过中性接触网换相供电,限流结束将可控变阻器阻值从最大调至零。装置隶属于接触网一个部门,装置运行与任何部门没有关联,利于规范化运行管理;接触网部门自行解决了列车自由过分相问题,司机可无过分相概念;装置成本低,接触网电分相结构形式及工程造价不变,适用范围不受限制,利于推广应用。
