A transmission device for easy opening and closing of AC high-voltage load switches

Abstract

This utility model discloses a transmission device for an AC high-voltage load switch that facilitates opening and closing, relating to the field of high-voltage load switch technology. It includes a support frame, a transmission belt module, a reducer, a connecting shaft, and a crank handle. The reducer is positioned above the support frame and is height-adapted to the high-voltage load switch. One end of the connecting shaft is connected to the reducer, and the other end is connected to a drive shaft. The transmission belt module includes a first pulley, a second pulley, and a transmission belt. The first pulley is connected to the support frame, and the second pulley is connected to the reducer. The support frame includes a first rotating shaft, with its transmission end located at the center of the first pulley. An external rotating column is located on the outer edge of the side wall of the first pulley away from the support frame. The crank handle can selectively engage with the outer circumference of the transmission end or the outer circumference of the external rotating column. The reducer reduces the rotational speed and increases the torque, allowing the user to input less force into the transmission belt module to drive the connecting shaft to rotate, thus opening and closing the high-voltage load switch, offering the technical advantage of effortless operation.
