[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1-5 , which is the first embodiment of the present invention, and provides a novel circuit breaker, including an insulating box 104, a mounting component 100, which includes a fixing member 101, a vacuum interrupter 102 arranged above the fixing member 101, and a fixing box 103 arranged at one side of the fixing member 101; a switch component 200, which includes a driving component 201 arranged at one side of the fixing member 101, a linkage component 202 arranged inside the fixing member 101, a transmission component 203 arranged inside the fixing box 103, and a moving component 204 arranged at one side of the transmission component 203; wherein the linkage component 202 is connected to the transmission component 203;

[0032] After the positions of the vacuum interrupter 102 and the fixed box 103 are fixed by the fixing part 101, the circuit breaker can be disconnected through the design of the driving component 201. Through the cooperation of the linkage component 202, the transmission component 203 and the moving component 204, the circuit breaker can be powered off after being disconnected. During the reverse operation, the circuit breaker circuit can be connected and then the internal connection of the circuit breaker can be completed, thereby avoiding mistakes caused by human subjective consciousness, which may lead to damage to the circuit breaker.

[0033] Furthermore, the fixing member 101 includes a base 101a and a mechanism box 101b disposed above the base 101a; wherein the vacuum interrupter 102 is fixedly disposed above the mechanism box 101b, the mechanism box 101b is fixedly connected to the base 101a, and the vacuum interrupter 102 is fixedly connected to the mechanism box 101b.

[0034] Furthermore, the driving assembly 201 includes a driving plate 201a arranged on one side of the mechanism box 101b, a worm 201c arranged on one side of the driving plate 201a, pull rings 201b arranged at both ends of the driving plate 201a, and a worm wheel 201d arranged above the worm 201c. Through the design of the pull ring 201b and the driving plate 201a, the staff located below can rotate the driving plate 201a through a hook with a telescopic rod. One end of the worm 201c is fixedly connected to the driving plate 201a. Through the design of the worm wheel 201d and the worm 201c, the worm 201c can drive the worm wheel 201d to rotate, and the worm wheel 201d will not drive the worm 201c to rotate in the reverse direction.

[0035] Furthermore, the linkage assembly 202 includes a rotating shaft 202a arranged inside the worm gear 201d, a rotating gear 202b arranged outside the rotating shaft 202a, and a rack 202c arranged below the vacuum arc extinguishing chamber 102. The rotating gear 202b is provided with multiple racks 202c respectively. The rotating shaft 202a is rotatably connected to the worm gear 201d, and the worm gear 201d is fixedly connected to the rotating shaft 202a. The rotating shaft 202a is supported inside the mechanism box 101b through a support plate. The rotation of the rotating shaft 202a drives the rotation of the rotating gear 202b, thereby driving the rack 202c to move downward, thereby disconnecting the inside of the new circuit breaker.

[0036] Furthermore, the transmission assembly 203 includes a pulley 203a arranged on the outside of the rotating shaft 202a, a transmission shaft 203d arranged inside the fixed box 103, a pulley 203b arranged on the outside of the transmission shaft 203d, and a transmission belt 203c arranged between the pulley 203b and the pulley 203a. The pulley 203a is fixedly connected to the rotating shaft 202a, and is fixedly connected to the pulley 203b and the transmission shaft 203d through the connection of the belt, so that the transmission shaft 203d rotates, thereby allowing the circuit breaker to disconnect.

[0037] Furthermore, the moving assembly 204 includes a threaded ring 204a arranged on the outside of the transmission shaft 203d, a moving plate 204b arranged on the outside of the threaded ring 204a, an insert plate 204c arranged on one side of the moving plate 204b, a slot 204d arranged on one side of the insert plate 204c, and a limiting plate 204e arranged on both sides of the moving plate 204b. The threaded ring 204a is fixedly connected to the transmission shaft 203d, and the moving plate 204b is threadedly connected to the threaded ring 204a. Due to the limitation of the limiting plate 204e, the moving plate 204b can only move left and right, and when the moving plate 204b moves to the outside of the limiting plate 204e, it rotates, and the insert plate 204c arranged on one side of the moving plate 204b is fixedly connected to the slot 204d.

[0038] Furthermore, a rotating plate 205a is provided on the outer side of the transmission shaft 203d, a rotating shaft 205b is provided on an upper end of the rotating plate 205a, a connecting rod 205c is provided on one side of the rotating shaft 205b, a conductive plate 205d is provided above the connecting rod 205c, a limiting column 205e is provided on the side above the base 101a away from the fixed box 103, the rotating plate 205a is rotatably connected to the rotating shaft 205b, and the limiting column 205e is used to limit the rear end of the conductive plate 205d while also limiting the rotation of the rotating plate.

[0039] Operation process: when disconnection is required, the driving plate 201a is rotated by the hook with the telescopic rod, thereby driving the rotation of the worm 201c, thereby driving the rotation of the worm wheel 201d, driving the rotation shaft 202a to rotate, thereby driving the rotation gear 202b to rotate, thereby driving the rack 202c to move downward, at this time, the pulley 1 203a will drive the pulley 2 203b to rotate through the belt, thereby driving the transmission shaft 203d to rotate, thereby driving the moving plate 204b to move to the right, so that the plug plate 204c and the card slot 204d are matched, at this time, when the moving plate 204b is away from the limit plate 204e, the moving plate 204b can rotate, so that the rotating plate 205a starts to move, and the connecting rod 205c is driven to move through the rotating shaft 205b, thereby driving the conductive plate 205d away from the new circuit breaker;

[0040] When it is necessary to connect, the driving plate 201a is rotated in the opposite direction, thereby driving the rotation of the worm 201c, thereby driving the rotation of the worm wheel 201d, driving the rotation shaft 202a to rotate, thereby driving the rotation gear 202b to rotate, thereby driving the rack 202c to move downward. At this time, the pulley 1 203a will drive the pulley 2 203b to rotate through the belt, thereby driving the transmission shaft 203d to rotate, thereby driving the moving plate 204b to move to the left, so that the plug plate 204c is away from the slot 204d. At this time, the moving plate 204b can only move horizontally. When the moving plate 204b enters the limit plate 204e, the rotating plate 205a has already contacted the new circuit breaker to form a passage.

[0042] Reference Figures 1 to 6, which is the second embodiment of the present invention, and is different from the previous embodiment in that it also includes a heat dissipation assembly 300, which includes a heat dissipation fan 301 arranged at the bottom of the insulation box 104, a heat dissipation hole 302 arranged at the top of the insulation box 104, and a busbar 303 arranged outside the insulation box 104. The heat dissipation assembly 300 is installed inside the insulation box 104 and consists of two heat dissipation fans 301 at the bottom of the insulation box 104 and two heat dissipation hole 302 filters at the top. Controlled by a thermostat in the insulation box 104, this ventilation will ensure air flow around the circuit breaker and the busbar 303, thereby guiding heat away from the circuit breaker.
