However, the existing rigid movable catenary system has extremely high costs, complex structures, inconvenient installation, high requirements for line usage conditions, and poor structural reliability. It uses an electric motor to drive the rotation of a rotating bracket, thereby driving the movement of the movable section of the overall mobile catenary to shift to one side of the railway track. In this method, the busbar is installed as a whole at the end of the rotating bracket, and there are many electric motors, making it difficult to control the synchronization of the motors or the electric push rods.
