The invention discloses a rigid catenary in-phase power supply device based on an urban subway electric traction system, and relates to the field of urban rail transit power supply, and the rigid catenary in-phase power supply device comprises two power supply mechanisms and an arc extinguishing mechanism which are symmetrically installed at the top of a subway train, the tail end of the lower arm rod is rotationally connected with an upper arm frame, and the bottom end of the upper arm frame is rotationally connected with a pull rod. According to the rigid contact network in-phase power supply device based on the urban subway electric traction system, the hard pipe is driven to move through the adjusting mechanism, when a subway advances forwards and backwards, the position of the hard pipe can be adjusted, a suppression medium sprayed out of the hard pipe can cover the arc discharge position of a pantograph head and a subway overhead line, the suppression effect on arc discharge is better, and the service life of the device is prolonged. And the situation that the arcing cannot be suppressed due to the fact that the suppression medium cannot be jetted to the arcing position of the pantograph head and the subway overhead line under the action of wind is avoided.
本发明公开了基于城市地铁电力牵引系统的刚性接触网同相供电装置,涉及城市轨道交通供电领域,包括两个对称安装于地铁列车顶部的供电机构和灭弧机构,供电机构包括底架和下臂杆,底架顶端通过A转轴与下臂杆转动连接,下臂杆末端转动连接有上臂架,上臂架底端转动连接有拉杆;该基于城市地铁电力牵引系统的刚性接触网同相供电装置,通过调节机构带动硬管移动,在地铁进行正反向行进时,能够调节硬管的位置,使硬管喷出的抑制介质能够覆盖住弓头与地铁架空线路产生拉弧处,对拉弧的抑制效果更好,避免抑制介质在风的作用下无法喷射至弓头与地铁架空线路产生拉弧处,导致无法进行抑制拉弧的情况发生。
