The invention relates to power transmission equipment and a control method thereof, and belongs to the technical field of new energy. The gun base is used for moving the power transmission gun in or out, one of the power transmission gun and the gun base is provided with a first magnetic device, the other one of the power transmission gun and the gun base is provided with a second magnetic device, and a plurality of magnetic poles with opposite polarities of the first magnetic device are alternately arranged in the same plane perpendicular to the first axis in the circumferential direction of the first axis; under the condition that the power transmission gun moves into the gun base, the second magnetic device and the first magnetic device are oppositely arranged along the first axis, and the driving device is used for driving the first magnetic device or the second magnetic device to rotate. The position of the second magnetic device relative to the first magnetic device is switched between a first position where the second magnetic device attracts each other and a second position where the second magnetic device repels each other. The first magnetic device or the second magnetic device is driven by the driving device to rotate, so that the first magnetic device and the second magnetic device attract or repel each other, a user is assisted to move the power transmission gun into or out of the gun seat, and the power transmission gun is labor-saving to plug and unplug.
