Auxiliary mounting device for ring main unit operation mechanism and working method thereof

The invention discloses an auxiliary mounting device for a ring main unit operation mechanism and a working method thereof. A ring main unit comprises an operation mechanism and an air box, wherein the air box is provided with a mounting station for mounting the operation mechanism. The auxiliary mounting device for the ring main unit operation mechanism comprises a mounting base, a clamping mechanism, a rotary driving mechanism and a moving mechanism, wherein the clamping mechanism is rotationally connected to the mounting base for acting in order to clamp the operation mechanism; the rotarydriving mechanism is connected between the mounting base and the clamping mechanism for acting to drive the clamping mechanism to rotate, and to drive the clamped operation mechanism to rotate to a mounting posture; and the moving mechanism is connected with the mounting base for driving the mounting base to move at least along the horizontal direction and the vertical direction. Through the adoption of the auxiliary moun
