[0078] By arranging the mounting assembly 10, four movable fixing points are formed on the surface of the circuit breaker switch 1, so that the circuit breaker switch 1 and the operation mechanism have higher adaptability, special models are not required, equipment cost can be saved, and the operation mechanism can be adjusted in a small range according to the position of the switch, so that the matching degree is higher and the control effect is better.

[0079] In combination with Embodiment 1-2, the working principle of the manual and automatic operation mechanism of the application is as follows:

[0080] Before installing the operation mechanism, push the two clamping plates 74 to the two sides respectively, move the movable rod 73 into the movable sleeve 72, push the piston plate 76 and the rotating disc 79 to move, so that the rotating control member 712 enters the butt joint groove 711, then drive the rotating disc 79 to rotate through the rotating control member 712, adjust the butt joint number of the avoidance hole 710 and the positioning hole 78, change the number of support between the rotating disc 79 and the movable rod 73, so that the support force provided by the support spring 75 corresponds to the force required for switch deflection, and then adjust the operation mechanism to the open gate state.

[0081] Align the bayonet 43 with the switch of the circuit breaker 1, fix the operation mechanism on the surface of the circuit breaker 1 by screw, and fill air into the extension pipe 83 by using the air blowing equipment. After the air enters the extension pipe 83, it first pushes the communication pipe 84 to stretch the air inlet spring 85 to slide to the air pipe 82 direction, until it is stopped by the limiting ring. At this time, the air hole 86 is communicated with the one end of the air pipe 82, and the air enters the movable sleeve 72 from the one end of the air pipe 82. The air pressure in the movable sleeve 72 increases, pushing the piston plate 76 to move towards the switch. The piston plate 76 pushes the clamping plate 74 to close to the switch through the support spring 75 and the movable rod 73, so that it is attached to the surface of the switch. Because the force required for switch deflection is large, the clamping plate 74 stops moving at this position, which causes the pressure in the extension pipe 83 to continuously increase. Then push away the air inlet closing plate 87, so that the air flows into the other end of the air pipe 82. The other side of the clamping plate 74 is also attached to the two.

[0082] When the switch needs to be closed, the manual control assembly 4 or the electric control assembly 5 drives the offset slider 42 to move, and the clamping plate 74 drives the switch to move. Because the closing action is completed in an instant, the air in the movable sleeve 72 and the air pipe 82 cannot be discharged in time, so the piston plate 76 will be supported by the air at this time, thereby keeping the clamping plate 74 stably clamped on the switch. Because the deflection amplitude of different switches is not fixed, when the switch completes the deflection before the stroke of the bayonet 43 ends, it cannot move any more. At this time, the offset slider 42 moves to press, a part of the support spring 75 penetrates the positioning hole 78 and the avoidance hole 710, and the other part of the support spring 75 is compressed to accumulate pressure. At the same time, the high pressure air in the air pipe 82 and the movable sleeve 72 pushes away the exhaust closing plate 810 to slowly discharge from the exhaust pipe 89. After the closing is completed, these high pressure air will continue to discharge, so that the air supports the piston plate 76 to move away from the movable rod 73, and the support spring 75 gradually expands. When the pressure in the movable sleeve 72 and the air pipe 82 is not enough to push away the exhaust closing plate 810, the exhaust closing spring 811 limits the exhaust closing plate 810 at the opening of the exhaust pipe 89, so as to close it.

[0083] When the electric closing is operated, the driving motor 51 is started, the transmission gear set 52 drives the transmission shaft 53 to rotate, the transmission shaft 53 drives the rotating contact piece 54 to rotate, the convex part of the rotating contact piece 54 pushes the offset sliding block 42 to one side through the pushing rod 55, the switch in the bayonet 43 moves following, the closing is completed, and meanwhile the movement of the bayonet 43 is transmitted to the connecting tooth box 45 through the connecting frame 44, the movement of the connecting tooth box 45 drives the rotating shaft gear 46 and the handle mounting 47 to rotate, so that the hand and the synchronization are realized. When the manual opening is operated, the handle mounting 47 is rotated by using a tool, the rotating shaft gear 46 is rotated following to drive the connecting tooth box 45 to offset to one side, the connecting tooth box 45 drives the offset sliding block 42 to move through the connecting frame 44, and the outside closing is realized.

[0084] In combination with Embodiment 3, the working principle of the circuit breaker is as follows:

[0085] After the operating mechanism is attached to the surface of the circuit breaker 1, the fixed frame 33 is corresponded with the mounting seat 102, then the screw is screwed into the threaded hole 103 through the fixed frame 33, at this time, the screw is only screwed into one third, then the position of the operating mechanism is adjusted, the state switching of the display shaft 92 is observed, after the adjustment is completed, the screw is completely screwed into the threaded hole 103, in the process, the screw pushes the fixed frame 33 to be close to the mounting seat 102, the fixed frame 33 constantly applies the pressure to the circuit breaker 1, and under the action of the friction force, the stable fixing is completed.

[0086] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
