Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, specifically to a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] Pole-mounted circuit breakers are widely used in power distribution systems to control and protect transmission lines. Currently, in the market, the terminals of integrated primary and secondary pole-mounted circuit breakers are exposed to the outdoor environment for extended periods during installation and maintenance, easily leading to the formation of an oxide layer. This oxide layer increases contact resistance, affects conductivity, and in severe cases, can cause poor contact or even overheating and burning. Existing practice is to use sandpaper or special tools for polishing, but this is inconvenient in high-altitude working conditions, requiring workers to carry multiple tools and increasing their workload.

[0003] Furthermore, during wiring, workers need to use wire strippers to remove the outer sheath of the wire before connecting it to the terminal block. This process requires repeatedly changing tools, stripping the wire, and then connecting it, which is inefficient. Especially during on-site operations, incomplete or lost tools can affect the construction progress. These problems have long existed in practical applications, and there is an urgent need for a circuit breaker device that can integrate grinding and wire stripping functions. Summary of the Invention

[0004] This invention provides a primary and secondary integrated pole-mounted circuit breaker that allows workers to quickly remove rust from terminals and strip wires without having to carry additional grinding tools and wire strippers during wiring, thereby improving on-site work efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: Firstly, a primary and secondary integrated pole-mounted circuit breaker includes a base shell and a closing / opening mechanism rotatably connected to the base shell. The base shell is equipped with an energy storage mechanism, a cable connector is provided on the front of the base shell, three support shells are evenly arranged on the base shell, an insulating shell is provided on the support shell, a current transformer is provided on the back of the support shell, a transmission mechanism is provided inside the base shell, and the drive end of the transmission mechanism is connected to the closing / opening mechanism. An insulating pull rod is connected to the output end of the transmission mechanism, and the insulating pull rod is vertically mounted inside the support shell. A flexible connection is connected to the upper end of the insulating pull rod, and a contact is connected to the flexible connection. An electrode is provided through the upper end of the insulating shell. The circuit breaker also includes: A terminal block is provided on the outside of the electrode by a fixing component. A wiring terminal is connected to one side of the terminal block. Two wiring holes are opened through the inside of the wiring terminal for connecting to the wire. The grinding end is located in the upper and lower directions of the terminal block. It includes a friction element that is correspondingly located on the upper and lower surfaces of the terminal block and is rotatably connected to the electrode. The friction element is used to grind both surfaces of the terminal block to remove the oxide layer. It also includes a spinning element that is circumferentially connected to the insulating shell. The spinning element is used to drive the friction element to contact the terminal block and drive the friction element to oscillate circumferentially along the insulating shell to achieve the grinding function. The spinning element is connected to the friction element. The biting and pulling part is located at the end of the grinding end and can be connected to the terminal block. It includes a support biting part fixed to the end of the friction part, the support biting part being used to bite through the outer sheath of the wire harness, and a hooking part being guided and connected to the support biting part. The hooking part is used to connect to the terminal block and pull off the bitten outer sheath of the wire harness when the spinning part rotates to complete the wire stripping operation.

[0006] Furthermore, the friction element includes an inclined plate disposed above the terminal block, the inclined plate having an inclination angle to be horizontal with the upper surface of the terminal block, a rotating plate disposed below the terminal block, the rotating plate being rotatable to adjust the grinding angle, and a grinding disc fixed to the side of the inclined plate and the rotating plate near the terminal block, the grinding disc being used to directly grind the oxide layer on the surface of the terminal block.

[0007] Furthermore, the spinning component includes a spinning pusher component disposed on the outside of the insulating shell, the spinning pusher component being used to make circumferential movements along the outside of the insulating shell, a collar sleeved on the outside of the upper end of the electrode and connected to the inclined plate, the collar being used to transmit the movement of the spinning pusher component to the inclined plate, a T-plate having one end fixed to the side of the collar away from the inclined plate and the other end connected to the lifting guide of the spinning pusher component, the T-plate being used to move up and down under the action of external force to drive the inclined plate to press or loosen the terminals of the grinding disc, and a pressure-pull component connected to the spinning pusher component and the spinning plate, the pressure-pull component being used to drive the spinning plate to rotate to realize the unfolding and retraction of the grinding disc.

[0008] Furthermore, the rotary push component includes an arc C-plate movably disposed on the outside of the insulating shell. The arc C-plate is C-shaped to facilitate fitting onto the outside of the insulating shell and moving along its circumference. Ball bearings are movably embedded in the inner top and bottom walls of the arc C-plate. The ball bearings are used to reduce friction and support the movement of the arc C-plate along the insulating shell. An arc plate is fixed to the upper end of the arc C-plate. The arc plate is used to connect and support the pressure and pull components. A guide groove is formed on the side of the arc plate near the electrode and is engaged with the other end of the T-plate for lifting and lowering guidance. The guide groove is used to provide guidance for the lifting and lowering movement of the T-plate.

[0009] Furthermore, the pressure-pull component includes a recessed hole in the arc plate, a spring disposed in the recessed hole, one end connected to the arc plate and the other end connected to the T plate, the spring being used to provide elastic support for the T plate and push the T plate to reset after the external force disappears, a ring sleeve fitted on the outside of the terminal block and fixed to the arc plate, the ring sleeve being used to transmit the circumferential motion of the arc plate to the rotating plate, and an L rod fixed on the end of the T plate away from the ring and located above the arc plate, the L rod being used to provide an operating force point so that the operator can apply force to press down the T plate.

[0010] Furthermore, the support includes a groove formed on the side of the ring sleeve away from the arc C plate and located outside the rotating plate, the groove being used to provide rotation space for the rotating plate; two bite plates respectively fixed to the ends of the inclined plate and the rotating plate, the bite plates being used to provide biting support surfaces; wire stripping teeth provided on the biting surfaces of the bite plates, the wire stripping teeth being sharp for biting through the outer sheath of the wire harness; and a biting part disposed through the ring sleeve, the biting part being used to pull the rotating plate to rotate under the action of external force so that the two bite plates come closer to each other to bite through the wire harness; the rotating plate is rotatably connected to the ring sleeve to realize the opening and closing movement of the bite plates.

[0011] Furthermore, the engagement component includes a guide hole that passes through the ring and communicates with the groove. The guide hole provides a passage and guide for the insulating rope. A pull block is symmetrically fixed on the outside of the rotating plate, located in the groove and close to the top. The pull block is used to transmit the tension of the insulating rope to the rotating plate. An insulating rope with a movable through-guide hole, one end connected to the pull block, and the other end movable through the arc plate and connected to the L rod, is used to pull the pull block to rotate the rotating plate when the L rod is pressed down to achieve the engagement action of the engagement plate.

[0012] Furthermore, the connecting member includes a T-groove formed on the biting surface of the bite plate, the T-groove being used to provide a moving guide space for the guide block, a guide block slidably disposed in the T-groove and connected to the stripping teeth, the guide block being used to support the stripping teeth and drive the stripping teeth to move under the action of external force to peel off the bitten wire sheath, and a pulling component disposed on one side of the guide block, the pulling component being used to pull the guide block to move during rotation to complete the wire stripping action.

[0013] Furthermore, the pulling component includes a hanging rope with one end located inside the T-groove and connected to the guide block, and movable through the biting surface of the biting plate. The hanging rope is used to pull the guide block to move in a taut state. The other end of the hanging rope is connected to a hook, which is used to pass through the wiring hole and suspend the connection to the wiring terminal to provide a fixed fulcrum, so that during rotation, the hanging rope can pull the guide block to drive the stripping teeth to peel off the bitten wire harness outer sheath.

[0014] The above-described solution of the present invention has at least the following beneficial effects: By incorporating a grinding end and a biting and pulling part, the terminal grinding and wire stripping operations are integrated. Workers only need to drive the spinning part with their hands to move the friction part to reciprocate grinding the terminal surface and remove the oxide layer. At the same time, the biting and pulling part can bite through the wire harness sheath, and with the help of the hanging part, the sheath can be directly peeled off during rotation. The whole process does not require additional tools, reducing the burden of carrying tools and improving wiring efficiency. It is especially suitable for high-altitude outdoor working environments.

Detailed Implementation

[0017] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0018] like Figures 1 to 8 As shown, an embodiment of the present invention provides a primary and secondary integrated pole-mounted circuit breaker, including a base shell 1 and a switching mechanism 4 rotatably connected to the base shell 1. The base shell 1 is provided with an energy storage mechanism 6, a cable connector 8 is provided on the front of the base shell 1, three support shells 9 are evenly arranged on the base shell 1, an insulating shell 10 is provided on the support shell 9, a current transformer 11 is provided on the back of the support shell 9, a transmission mechanism 13 is provided inside the base shell 1, and the driving end of the transmission mechanism 13 is connected to the switching mechanism 4. The output end of the transmission mechanism 13 is connected to an insulating pull rod 14, and the insulating pull rod 14 is vertically arranged inside the support shell 9. A flexible connection 15 is connected to the upper end of the insulating pull rod 14, and a contact 16 is connected to the flexible connection 15. An electrode 18 is provided through the upper end of the insulating shell 10. The circuit breaker also includes: A terminal block 19 is provided on the outside of the electrode 18 by a fixing component. A wiring terminal 20 is connected to one side of the terminal block 19. Two wiring holes 21 are opened through the inside of the wiring terminal 20. The grinding end is set in the upper and lower directions of the terminal 20. It includes a friction element that is correspondingly set on the upper and lower surfaces of the terminal 20 and rotatably connected to the electrode 18 for grinding the two surfaces of the terminal 20, and a spinning element that is circumferentially connected to the insulating shell 10 for driving the friction element to contact the terminal 20. The spinning element is connected to the friction element. The biting and pulling part is provided at the end of the grinding end and can be connected to the terminal 20. It includes a support biting member fixed to the end of the friction member for biting through the outer sheath of the wire harness, and a hook member guided and connected to the support biting member for connecting to the terminal 20, so as to pull down the bitten outer sheath of the wire harness when the spinning member rotates.

[0019] Specifically, the bottom shell 1 has side plates 2 fixed on both sides, and a handle 3 is rotatably connected to the outer side of the side plates 2. The bottom shell 1 has a rotatable closing indicator 5 on the front, which cooperates with the opening and closing mechanism 4. The bottom shell 1 has an energy storage motor 12 installed inside, which is connected to the energy storage mechanism 6. The inner side of the insulating shell 10 has a vacuum interrupter 17, and the contacts 16 and electrodes 18 are located inside the vacuum interrupter 17.

[0020] The bottom shell 1 provides stable support for the side plate 2 and the support shell 9. The support shell 9 provides support for the insulating shell 10. The side plate 2 provides rotational support for the handle 3. The handle 3 allows the operator to easily lift the circuit breaker and move it. The support shell 9 and the insulating shell 10 are made of insulating material, which can provide protection for their internal facilities. The vacuum interrupter 17 can perform arc extinguishing, thereby protecting the electrode 18 and the contact 16. The electrode 18 and the contact 16 can conduct electricity when in contact, and the current transformer 11 can sense the current.

[0021] In practical application, the operator can move the circuit breaker to the work location using handle 3 as needed, and fix it in place using the fixing component that passes through the side plate 2. This allows the side plate 2 to stably support the base shell 1. The base shell 1 is then grounded, and the power transmission circuit is electrically connected from the wiring hole 21 to the terminal 20. Simultaneously, the sensing circuit is connected to the current transformer 11 for current detection. The cable is then plugged into the cable connector 8. The operator can then push the opening / closing mechanism 4 to rotate under the support of the base shell 1, causing the opening / closing mechanism 4 to rotate according to the direction of rotation via transmission. Mechanism 13 pushes the insulating rod 14 to move up or down. When the opening and closing mechanism 4 rotates clockwise, it will push the insulating rod 14 to move upward along the support shell 9 through the transmission mechanism 13, so that the insulating rod 14 can push the contact 16 upward through the flexible connection 15, so that the contact 16 contacts the electrode 18 to make conductive connection, thereby realizing the closing operation. At the same time, the closing indicator 5 will cooperate with the opening and closing mechanism 4 to rotate clockwise, thereby indicating the position of the closing mark. When the opening and closing mechanism 4 rotates counterclockwise, the movement directions of the insulating rod 14 and the closing indicator 5 are opposite, so that the contact 16 separates from the electrode 18 to realize the opening, and at the same time, the closing indicator 5 points to the position of the opening mark.

[0022] According to the actual needs, the staff can rotate the energy storage mechanism 6 clockwise, so that the energy storage mechanism 6 drives the drive end of the energy storage motor 12 to rotate, thereby making the energy storage motor 12 run to perform energy storage work. At the same time, the energy storage mechanism 6 will cooperate with the transmission mechanism 13 to make the energy storage indicator 7 rotate counterclockwise to point to the position of the energy storage mark.

[0023] In a preferred embodiment of the present invention, the friction element includes: Inclined plate 22 is positioned above terminal block 20; Rotary plate 23 is located below terminal block 20; The grinding disc 24 is fixed on the side of the inclined plate 22 and the rotating plate 23 near the terminal 20.

[0024] Specifically, the inclined plate 22 has an inclination angle and can be horizontal with the terminal 20. The edge of the polishing disc 24 is curved to facilitate movement to the surface of the terminal 20 during swinging. Side wing plates 45 are symmetrically arranged on both sides of the inclined plate 22 and the rotating plate 23. During the rotation of the side wing plates 45, the terminal 20 can provide a blocking effect for the side wing plates 45, thereby allowing the side wing plates 45 to provide a limiting effect for the rotating plate 23 and the inclined plate 22. Rotating rods 34 are symmetrically arranged on the outer side of the rotating plate 23. The rotating rods 34 are rotatably connected to the ring 32. The inclined plate 22 and the rotating plate 23 can provide stable support for the polishing disc 24. The inclined plate 22 has an inclination angle, and the rotating plate 23 can rotate as needed, so that the polishing disc 24 can fit against the terminal 20. This allows the polishing disc 24 to use external force to polish the oxide layer generated on the outer side of the terminal 20. At the same time, the rotatable rotating plate 23 ensures that the setting of the polishing disc 24 will not affect the connection circuit of the terminal 20.

[0025] Spinning parts include: The rotary push part is located on the outside of the insulating shell 10; The collar 25 is sleeved on the outer side of the upper end of the electrode 18 and connected to the inclined plate 22; T-plate 26, one end is fixed to the side of collar 25 away from inclined plate 22, and the other end is connected to the lifting guide of the rotary push part; The pressure-pull component is connected to the rotary-push component and the rotary plate 23.

[0026] Specifically, electrode 18 provides a limiting function for collar 25, which in turn provides stable support for T-plate 26.

[0027] The rotary pusher components include: Arc C plate 27 is movably disposed on the outside of insulating shell 10; Ball bearing 47 is movably embedded in the inner top and bottom walls of the arc C plate 27; Arc plate 28 is fixed to the upper end of arc C plate 27; The guide groove 29 is formed on the side of the arc plate 28 near the electrode 18 and is engaged with the other end of the T plate 26 for lifting and guiding.

[0028] Specifically, the guide groove 29 can provide a guiding function for the lifting and moving of the T plate 26, the arc plate 28 can provide a space for the guide groove 29, the cross-sectional shape of the arc C plate 27 is the same as the outline of the insulating shell 10, and can be C-shaped and fitted on the outside of the insulating shell 10. The arc C plate 27 can provide rolling support for the ball 47, and the ball 47 can roll along the insulating shell 10 under the push of external force by friction, so that the arc C plate 27 can move around the circumference of the insulating shell 10.

[0029] Compression and tension components include: A recessed hole 30 is formed inside the arc plate 28; Spring 31 is set in concave hole 30, one end of which is connected to arc plate 28 and the other end is connected to T plate 26; The ring 32 is sleeved on the outside of the terminal block 19 and fixedly connected to the arc plate 28; L-rod 38 is fixed to the end of T-plate 26 away from collar 25 and located above arc C-plate 27.

[0030] Specifically, the arc plate 28 has an opening 46 on the side away from the collar 25, and the opening 46 is connected to the guide groove 29, which can provide space for the L rod 38 to pass through and move. The arc plate 28 can provide space for the recessed hole 30, and the recessed hole 30 can provide space for the spring 31 to move. The spring 31 is elastic and can provide support for the T plate 26. The terminal seat 19 can provide rotation limit for the collar 32. The T plate 26 can provide stable support for the L rod 38. The L rod 38 can facilitate the operator to press down the T plate 26 in cooperation with the arc plate 27. After the external force of the T plate 26 pressing the spring 31 disappears, the spring 31 will use the rebound force to push the T plate 26 upward to reset under the support of the arc plate 28.

[0031] In practical application, when it is necessary to remove the oxide layer on the terminal 20, the worker can press their thumb on the L-rod 38 and place the other four fingers on the lower end of the arc C-plate 27. With the arc C-plate 27 providing resistance, the worker can use their thumb to press down on the L-rod 38, causing the L-rod 38 to move the T-plate 26 downwards along the guide groove 29. Simultaneously, the T-plate 26 will compress the spring 31 during its downward movement, causing the spring 31 to be compressed and retracted into the concave hole 30 under the support of the arc plate 28. When the T-plate 26 moves downwards via the collar 25, it causes the inclined plate 22 to move downwards along with the side wing plate 45 and the grinding disc 24 connected to it. This allows the grinding disc 24 to come into contact with the terminal 20. Simultaneously, as the L-rod 38 moves downwards, it causes the end of the insulating rope 37 away from the rotating plate 23 to move downwards as well. When the L-rod 38 reaches its downward limit, the insulating rope 37 can be pulled by the L-rod 38 to pass through the arc plate 28 and move along the guide hole 35 towards the L-rod 38. The insulating rope 37 changes its direction of movement (its end moves downward) under the resistance of the arc plate 28. This allows the insulating rope 37 to pull the pull block 36 closer to the guide hole 35 under external force. The pull block 36, under the influence of external force, drives the inclined plate 22 and the rotating rod 34 to rotate clockwise within the groove 33, supported by the ring sleeve 32 and centered on the rotating rod 34. This allows the inclined plate 22 to drive the grinding disc 24 and the side wing plate 45 connected to it to rotate clockwise together, enabling the grinding disc 24 at this location to connect with the terminal block. After contacting the lower part of terminal 20, the operator needs to use L rod 38 and arc C plate 27 to make reciprocating circular swings around the insulating shell 10. This allows arc C plate 27 to drive ring 32 and collar 25 to swing together on the outside of terminal base 19 and electrode 18 via arc plate 28 and T plate 26. Then, through inclined plate 22 and rotating plate 23, grinding disc 24 is driven to swing together. This allows grinding disc 24 to grind and clean the oxide layer on terminal 20 during the swing process, preventing the oxide layer from affecting the conductivity.

[0032] In a preferred embodiment of the present invention, the support member includes: The groove 33 is formed on the side of the ring 32 away from the arc C plate 27 and is located on the outside of the rotating plate 23; Rotary plate 23 is rotatably connected to ring sleeve 32; There are two bite plates 39, which are respectively fixed to the ends of the inclined plate 22 and the rotating plate 23; Stripping teeth 41 are located on the biting surface of the bite plate 39; Engaging parts, with a through-ring sleeve 32.

[0033] Specifically, the groove 33 provides rotation space for the rotating plate 23, the rotating plate 23 and the inclined plate 22 provide stable support for the biting plate 39, and the stripping teeth 41 can bite through the outer sheath of the wire harness placed between the two biting plates 39 after the L rod 38 moves down to its limit.

[0034] The engaging parts include: A guide hole 35 is provided through the ring sleeve 32 and communicates with the groove 33; Pull block 36 is symmetrically fixed on the outside of rotary plate 23, located in groove 33, and close to the top; An insulating rope 37 is provided with a movable through-hole 35. One end is connected to a pull block 36, and the other end is movable through an arc plate 28 and connected to an L rod 38.

[0035] Specifically, the ring 32 provides space for the guide hole 35, the guide hole 35 provides a through channel and guide for the insulating rope 37, the insulating rope 37 can be bent under the action of external force, and can use external force to pull the pull block 36, so that the pull block 36 can pull the rotating plate 23 to rotate clockwise around the rotating rod 34.

[0036] The fasteners include: T-groove 40 is formed on the occlusal surface of bite plate 39; Guide block 42 is slidably disposed within T-groove 40; Guide block 42 is connected to stripping tooth 41; The pull-out component is located on one side of the guide block 42.

[0037] Specifically, the bite plate 39 provides space for the T-groove 40, the T-groove 40 provides a moving guide for the guide block 42, the guide block 42 provides support for the stripping teeth 41, and the biting end of the stripping teeth 41 is sharp.

[0038] The pull-out parts include: The hanging rope 43 has one end located inside the T-groove 40 and is connected to the guide block 42; The hanging rope 43 is set to extend through the biting surface of the bite plate 39; Hook 44 is attached to the other end of the hanging rope 43 and is used to connect to the wiring hole 21.

[0039] Specifically, the T-groove 40 provides space for the hanging rope 43 to move, the guide block 42 provides support for one end of the hanging rope 43, and the bite plate 39 provides a through channel for the hanging rope 43. The hanging rope 43 can be connected to the hook 44, and the hook 44 can be suspended and connected to the terminal 20 through the wiring hole 21. The friction between the guide block 42 and the T-groove 40 can provide support for the stripping teeth 41.

[0040] In practical application, before connecting the wire to the terminal 20, the operator can suspend the hook 44 to the terminal 20 through the wiring hole 21, keeping the hanging rope 43 taut. Then, place one end of the wire to be connected into the space between the two biting plates 39, and then press down on the L-rod 38, causing the rotating plate 23 and the inclined plate 22 to move closer to the terminal 20. This allows the inclined plate 22 and the rotating plate 23 to move the two biting plates 39 closer together. Simultaneously, the biting plates 39, through the guide block 42, drive the stripping teeth 41 to move closer to the wire, allowing the stripping teeth 41 to bite through the wire's outer sheath using external force and their sharp ends. Afterward, the operator needs to push the arc C-plate 27 to rotate along the outside of the insulation shell 10, while simultaneously using the ring 32 and the collar 25... The inclined plate 22 and the rotating plate 23 drive the biting plate 39 and the stripping teeth 41 to rotate together. The biting plate 39 will drive the end of the hanging rope 43 away from the electrode 18 to rotate around the electrode 18 as the center, while the end of the hanging rope 43 near the terminal 20 will be positioned in place by the terminal 20. Thus, the biting plate 39 can drive the hanging rope 43 to bend and wrap during rotation, thereby indirectly shortening the length of the hanging rope 43. This allows the hanging rope 43 to pull the guide block 42 along the T-groove 40 towards the electrode 18 during rotation. Under the action of external force, the guide block 42 can drive the stripping teeth 41 to move towards the electrode 18. This allows the stripping teeth 41 to move and peel off the bitten wire sheath during the movement, thereby improving the efficiency of wire stripping and connection compared to using a wire stripping tool.

[0041] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
