Therefore, the 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figures 1 to 8 This is the first embodiment of the present invention. This embodiment provides a primary and secondary integrated pole-mounted circuit breaker. The primary and secondary integrated pole-mounted circuit breaker includes a main body component 100 and a limiting component 200. By setting the limiting component 200, the position of the operating rod 103d can be limited, thereby preventing the isolation knife from closing due to the worker's touch, which could cause the worker to be electrocuted and cause a safety accident.

[0032] Specifically, the main component 100 includes a circuit breaker 101, a support member 102, a drive member 103, a connector 104, and an outgoing terminal 105. The support member 102 is disposed on one side of the circuit breaker 101, the drive member 103 is located inside the support member 102, the connector 104 is disposed on the circuit breaker 101, and the outgoing terminal 105 is located on the top of the circuit breaker 101; and,

[0033] The circuit breaker 101 is used to provide overvoltage protection for the circuit and to control the on and off of the circuit. The support member 102 is used to support and fix the drive member 103 and the connector 104. The drive member 103 is used to drive the connector 104 to operate, so that the connector 104 controls the on and off of the circuit. The output terminal 105 is used to connect the output line.

[0034] The limiting assembly 200 is disposed on one side of the circuit breaker 101 and includes an adjusting member 201, a positioning member 202, a limiting member 203, a blocking member 204, a resetting member 205, and a fixing shell 206. The adjusting member 201 is disposed on one side of the driving member 103, the positioning member 202 is disposed on one side of the circuit breaker 101, the limiting member 203 is disposed on one side of the circuit breaker 101, the blocking member 204 is disposed on one side of the circuit breaker 101, the resetting member 205 is disposed on one side of the circuit breaker 101, and the fixing shell 206 is disposed on one side of the circuit breaker 101.

[0035] Adjusting member 201 is used to adjust the position of positioning member 202. Positioning member 202 is used to limit the position of driving member 103. Limiting member 203 is used to position the driving member 103. Blocking member 204 is used to block the driving member 103 and reset member 205. Reset member 205 is used to push limiting member 203 to perform an action, thereby releasing the limit on driving member 103 and causing driving member 103 to reset the closed circuit.

[0036] Specifically, the support member 102 includes a support frame 102a, an angle iron 102b, a post insulator 102c, and an incoming terminal 102d. The support frame 102a is located on one side of the circuit breaker 101, the angle iron 102b is located at the end of the support frame 102a, the post insulator 102c is located on the top of the angle iron 102b, and the incoming terminal 102d is located on the top of the post insulator 102c.

[0037] The support frame 102a is fixed to one side of the circuit breaker 101 by welding. The angle iron 102b is fixed to the end of the support frame 102a by bolts. It is used to support and fix the post insulator 102c. There are three post insulators 102c, all of which are fixed to the top of the angle iron 102b. The post insulators 102c are made of insulating material to prevent current from being conducted from the input terminal 102d to the support frame 102a. The input terminal 102d is fixed to the top of the post insulator 102c and is used to connect the input line.

[0038] Specifically, the drive component 103 includes a drive shaft 103a, a positioning ring 103b, a rotating frame 103c, and an operating lever 103d. The drive shaft 103a is disposed inside the support frame 102a, the positioning ring 103b is located on the surface of the drive shaft 103a, the rotating frame 103c is disposed on the surface of the drive shaft 103a, and the operating lever 103d is located at the end of the drive shaft 103a.

[0039] The drive shaft 103a is rotatably connected to the support frame 102a. There are two positioning rings 103b, both fixed to the surface of the drive shaft 103a, which are used to limit the drive shaft 103a. There are three rotating frames 103c, all fixed to the surface of the drive shaft 103a. The operating lever 103d is fixed to the surface of the drive shaft 103a. By rotating the operating lever 103d, the drive shaft 103a can be rotated, thereby causing the three rotating frames 103c to deflect, which in turn causes the connecting piece 104 to move, thereby controlling the on and off of the circuit.

[0040] Specifically, the connector 104 includes an isolating blade 104a and an operating insulator 104b. The isolating blade 104a is disposed on one side of the circuit breaker 101, and the operating insulator 104b is located inside the isolating blade 104a.

[0041] There are three isolating blades 104a, one end of which is rotatably connected to one side of the circuit breaker 101 via a rotating shaft, and the other end is sleeved on the surface of the incoming terminal 102d to connect the incoming terminal 102d and the circuit breaker 101. There are three operating insulators 104b, one end of which is rotatably connected to the isolating blade 104a via a rotating shaft, and the other end of which is rotatably connected to the rotating frame 103c via a rotating shaft. The operating insulators 104b are made of insulating material. When the rotating frame 103c deflects, it can drive the operating insulators 104b to rise and fall, thereby controlling the isolating blade 104a to move away from or closer to the incoming terminal 102d, thereby controlling the opening and closing of the circuit. When it is necessary to disconnect the circuit, the operator first disconnects the circuit inside the circuit breaker 101, and then separates the isolating blades 104a, thereby preventing the isolating blade 104a from generating an electric arc when disconnected.

[0042] Example 2

[0043] Reference Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, the adjusting component 201 includes a fixed handle 201a, a slide rod 201b, a first spring 201c, a pressing plate 201d, a sliding plate 201e, and a positioning sleeve 201f. The fixed handle 201a is located on one side of the operating rod 103d, the slide rod 201b is located on one side of the fixed handle 201a, the first spring 201c is located on the surface of the slide rod 201b, the pressing plate 201d is located on the surface of the slide rod 201b, the sliding plate 201e is located on one side of the operating rod 103d, and the positioning sleeve 201f is located on one side of the operating rod 103d.

[0045] The fixed handle 201a is fixed to one side of the operating rod 103d by welding. There are two slide rods 201b, both fixed to one side of the fixed handle 201a. There are two first springs 201c, both sleeved on the surface of the slide rod 201b. The extrusion plate 201d slides on the surface of the slide rod 201b, and a protrusion is provided at the end of the surface of the slide rod 201b to limit the extrusion plate 201d and prevent it from sliding out of the surface of the slide rod 201b. There are multiple positioning sleeves 201f, all fixed to one side of the operating rod 103d by welding or other fixing methods. The slide plate 201e slides inside the positioning sleeve 201f. At the same time, the slide plate 201e passes through the fixed handle 201a and is fixed to one side of the extrusion plate 201d. When the operator holds the fixed handle 201a and the extrusion plate 201d, the extrusion plate 201d is pressed against the fixed handle 201a, thereby pushing the slide plate 201e to slide inside the positioning sleeve 201f.

[0046] Specifically, the adjusting component 201 also includes a connecting plate 201g and a push plate 201h. The connecting plate 201g is located on one side of the slide plate 201e, and the push plate 201h is located on one side of the connecting plate 201g.

[0047] The connecting plate 201g is rotatably connected to one side of the slide plate 201e via a rotating shaft. The other end of the connecting plate 201g is rotatably connected to one side of the push plate 201h via a rotating shaft. The push plate 201h slides inside the positioning sleeve 201f. A pressing block is provided at the end of the push plate 201h. When the slide plate 201e is pushed by the pressing plate 201d, the slide plate 201e will push the push plate 201h to slide through the connecting plate 201g, thereby causing the push plate 201h to push the positioning member 202 to move, thereby releasing the positioning member 202 from limiting the operation lever 103d.

[0048] Specifically, the positioning component 202 includes a fixed sleeve 202a, a sliding sleeve 202b, a second spring 202c, a fixed block 202d, a third spring 202e, and a telescopic rod 202f. The fixed sleeve 202a is located on one side of the circuit breaker 101, the sliding sleeve 202b is located inside the fixed sleeve 202a, the second spring 202c is located inside the sliding sleeve 202b, the fixed block 202d is located on one side of the circuit breaker 101, the third spring 202e is located inside the sliding sleeve 202b, and the telescopic rod 202f is located inside the sliding sleeve 202b.

[0049] The fixed sleeve 202a is fixed to one side of the circuit breaker 101 by welding. The sliding sleeve 202b slides inside the fixed sleeve 202a. The two ends of the second spring 202c are fixed to the inner wall of the sliding sleeve 202b and one side of the fixed block 202d, respectively. The fixed block 202d is fixed to one side of the circuit breaker 101 by welding. The two ends of the third spring 202e are fixed to the end of the telescopic rod 202f and the inner wall of the sliding sleeve 202b, respectively. The sliding of the sliding sleeve 202b can drive the telescopic rod 202f to move to the side of the operating rod 103d, thereby limiting the operating rod 103d and preventing the isolating knife 104a from accidentally separating when it comes into contact with the incoming terminal 102d.

[0050] Example 3

[0051] Reference Figures 4-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, the limiting component 203 includes a support column 203a, a support sleeve 203b, a limiting rod 203c, a sector gear 203d, a rack 203e, a fixing frame 203f, a limiting block 203g, a fixing plate 203h, a fourth spring 203i, a limiting pin 203j, and a reset block 203k. The support column 203a is located on one side of the circuit breaker 101, the support sleeve 203b is located on the surface of the support column 203a, and the limiting rod 203c is located on the support sleeve 203b. On the surface, sector gear 203d is located on the surface of support sleeve 203b, rack 203e is located on one side of sector gear 203d, fixing frame 203f is located on one side of circuit breaker 101, limiting block 203g is located inside fixing frame 203f, fixing plate 203h is located on one side of limiting block 203g, fourth spring 203i is located on one side of fixing plate 203h, limiting pin 203j is located inside fixing frame 203f, and reset block 203k is located on one side of sector gear 203d.

[0053] Support column 203a is fixed to one side of circuit breaker 101 by welding. Support sleeve 203b is rotatably connected to the surface of support column 203a. Limiting rod 203c is fixed to the surface of support sleeve 203b by welding and is used to limit the operation rod 103d. Sector gear 203d is fixed to the surface of support sleeve 203b by welding. Sector gear 203d is a semi-circular gear, and its center is located at the center of support column 203a. Rack 203e is fixed to one side of sliding sleeve 202b by welding, and rack 203e and sector gear 203d mesh. The frame 203f is fixed to one side of the circuit breaker 101 by welding. The limiting block 203g slides inside the fixed frame 203f and is used to limit the sector gear 203d. The fixing plate 203h is fixed to one side of the limiting block 203g by welding. The two ends of the fourth spring 203i are fixed to one side of the fixing plate 203h and one side of the fixed frame 203f, respectively, and are used to pull the limiting block 203g toward the circuit breaker 101. The limiting pin 203j slides inside the limiting block 203g and is located on one side of the fixed frame 203f. One side of the limiting pin 203j is provided with an arc-shaped surface, which can be moved by... The movable limit pin 203j allows the limit block 203g to be moved away from the circuit breaker 101 by the arc-shaped surface. The reset block 203k is fixed to one side of the sector gear 203d by welding. When the limit block 203g is away from the circuit breaker 101, rotating the operating lever 103d causes the operating lever 103d to move the limit lever 203c, thereby driving the sector gear 203d to rotate. This causes the reset block 203k to move towards the limit pin 203j, thus pushing the limit pin 203j to reset. When the operating lever 103d moves to the other side of the limit lever 203c, the isolation... The blade 104a and the incoming terminal 102d are in contact. At the same time, under the pushing force of the second spring 202c, the sliding sleeve 202b can drive the telescopic rod 202f to move to one side of the end of the operating rod 103d, thereby limiting the position of the operating rod 103d and preventing the operating rod 103d from deflecting. While the sliding sleeve 202b moves, the rack 203e can drive the sector gear 203d to rotate, thereby causing the limiting block 203g to slide off the sector gear 203d. Under the pulling force of the fourth spring 203i, the limiting block 203g can be driven to stick tightly to the surface of the circuit breaker 101.

[0054] Specifically, the barrier component 204 includes a limiting sleeve 204a, a barrier plate 204b, a fifth spring 204c, and a support block 204d. The limiting sleeve 204a is located on one side of the circuit breaker 101, the barrier plate 204b is located inside the limiting sleeve 204a, the fifth spring 204c is located at the end of the barrier plate 204b, and the support block 204d is located on one side of the circuit breaker 101.

[0055] The limiting sleeve 204a is fixed to one side of the circuit breaker 101 by welding to limit the baffle plate 204b. The baffle plate 204b slides inside the limiting sleeve 204a. The two ends of the fifth spring 204c are fixed to the end of the baffle plate 204b and one side of the support block 204d, respectively. The support block 204d is fixed to one side of the circuit breaker 101 by welding. When the operator holds the fixed handle 201a and pulls it upward, the end of the operating rod 103d will move to the side of the baffle plate 204b, thus preventing it from directly contacting the reset piece 205. This avoids directly releasing the limiting rod 203c, allowing the limiting rod 203c to remain in place. The end of the operating lever 103d can be limited between the limiting lever 203c and the baffle 204b to prevent the isolation knife 104a from closing due to accidental contact by the operator. When it is necessary to release the limitation of the limiting lever 203c, when the end of the operating lever 103d is located on the side of the baffle 204b, the fixed handle 201a and the pressing plate 201d are gripped tightly, so that the push plate 201h pushes the baffle 204b open, so that the end of the operating lever 103d can press the reset member 205, so that the reset member 205 drives the limiting block 203g to move, thereby releasing the limitation of the limiting lever 203c.

[0056] Specifically, the reset component 205 includes a fixed post 205a, a rotating sleeve 205b, a drive rod 205c, a reset rod 205d, a positioning plate 205e, a sixth spring 205f, and a column 205g. The fixed post 205a is located on one side of the circuit breaker 101, the rotating sleeve 205b is located on the surface of the fixed post 205a, the drive rod 205c is located on the surface of the rotating sleeve 205b, the reset rod 205d is located on the surface of the rotating sleeve 205b, the positioning plate 205e is located on one side of the circuit breaker 101, the sixth spring 205f is located on one side of the positioning plate 205e, and the column 205g is located on one side of the circuit breaker 101.

[0057] The fixed column 205a is fixed to one side of the circuit breaker 101 by welding. The rotating sleeve 205b is rotatably connected to the surface of the fixed column 205a. The drive rod 205c is fixed to the surface of the rotating sleeve 205b by welding. The reset rod 205d is fixed to the surface of the rotating sleeve 205b by welding. The positioning plate 205e is fixed to one side of the circuit breaker 101 by welding to limit the reset rod 205d. The sixth spring 205f is fixed at both ends to one side of the reset rod 205d and one side of the column 205g, respectively. The column 205g is fixed by welding. On the side of circuit breaker 101, when the end of the operating lever 103d presses against the drive lever 205c, the drive lever 205c drives the rotating sleeve 205b to rotate, thereby driving the reset lever 205d to rotate. This causes the reset lever 205d to push the limit pin 203j to move, so that the limit pin 203j drives the limit block 203g away from the circuit breaker 101, thereby releasing the limit on the sector gear 203d. When the end of the operating lever 103d moves away from the drive lever 205c, under the reset pulling force of the sixth spring 205f, the reset lever 205d can be reset.

[0058] In use, when it is necessary to disconnect the power transmission line, first disconnect the circuit breaker 101, then have the operator hold the fixed handle 201a and the pressing plate 201d, pressing the pressing plate 201d against the fixed handle 201a, thereby pushing the sliding plate 201e to slide within the positioning sleeve 201f, which in turn causes the push plate 201h to push the telescopic rod 202f to retract into the sliding sleeve 202b, thereby releasing the limitation of the telescopic rod 202f on the operating rod 103d. At this time, the fixed handle 201a can be moved, thereby moving the end of the operating rod 103d to the side of the limiting rod 203c. At this time, the push plate 201h is located at the end of the operating rod 103d. As the operating lever 103d moves, the push plate 201h will first contact the baffle plate 204b, thereby limiting the operating lever 103d. At this time, the fixed handle 201a is released, and the operating lever 103d moves towards the limiting rod 203c under its own weight. Since the sector gear 203d is limited by the limiting block 203g at this time, the support sleeve 203b cannot rotate, thereby limiting the operating lever 103d by the limiting rod 203c, preventing the isolating knife 104a from contacting the incoming terminal 102d, thus avoiding accidental contact between the isolating knife 104a and the incoming terminal 102d, which could cause electric shock to the staff.

[0059] When it is necessary to connect the transmission line, first connect the isolating blade 104a and the incoming terminal 102d, then connect the circuit breaker 101. When connecting the isolating blade 104a and the incoming terminal 102d, first move the fixed handle 201a so that the end of the operating lever 103d moves to the side of the baffle plate 204b. At this time, the fixed handle 201a and the pressing plate 201d can be squeezed to push the push plate 201h towards the end of the operating lever 103d, thereby releasing the baffle plate 204b. 04b limits the operation lever 103d, allowing it to press the drive lever 205c. The drive lever 205c drives the reset lever 205d to rotate, causing it to move the limit pin 203j. This, in turn, moves the limit pin 203j away from the circuit breaker 101, releasing the limit on the sector gear 203d. At this point, pulling down the fixed handle 201a moves the end of the operation lever 103d toward the limit lever 203c, thus resetting the limit. The lever 203c drives the sector gear 203d to rotate. The sector gear 203d can drive the reset block 203k to press the limit pin 203j, causing the limit pin 203j to reset. When the operating lever 103d moves to the other side of the limit lever 203c, the isolating knife 104a and the inlet terminal 102d merge. The operating lever 103d is limited by the telescopic rod 202f pushed out by the second spring 202c, preventing the operating lever 103d from rotating and causing the isolating knife 104a and the inlet terminal 102d to separate. As the telescopic rod 202f is pushed out by the second spring 202c, the rack 203e drives the sector gear 203d to rotate, causing the limiting block 203g to slide off the sector gear 203d. Under the pulling force of the fourth spring 203i, the limiting block 203g is pressed tightly against one side of the circuit breaker 101 to limit the sector gear 203d. By combining the isolating knife 104a and the incoming terminal 102d, electric shock incidents caused by accidental contact by staff can be avoided.
