Rocker arm device for switching operation of transformer station

The invention provides a rocker arm device for switching operation of a transformer station, and relates to an electric rocker arm device. When the transformer station is routinely overhauled and replaced, a rocker arm is needed to pull a power capacitor trolley out of a machine cabinet or push the power capacitor trolley into the machine cabinet, and large torque and high strength are needed to rotate the rocker arm. The rocker arm device comprises a mobile trolley, an electric lifting table, a direct current motor and a controller. The mobile trolley is provided with a storage battery, the electric lifting table is arranged on the trolley, the direct current motor is arranged on the electric lifting table, and the controller controls the direct current motor to rotate and the electric lifting table to lift. The storage battery is connected with the electric lifting table, the rotating direct current motor and the controller to supply power. The direct current motor is rotated to drive the capacitor trolley
