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] Circuit breakers are indispensable circuit components. In a circuit, they are current switching devices that can open and close and carry abnormal circuits. They are an important part of ensuring circuit safety. Electricity transmission is a complex process. In the case of long-distance power transmission, circuit breakers are electrical appliances used in large quantities. Generally, a circuit breaker is installed at intervals. At present, ordinary circuit breakers do not integrate electronic control technology and must rely on the distribution automation master station and communication. However, the integrated primary and secondary pole-mounted circuit breaker integrates industry-leading electronic components and can realize distribution automation functions without relying on the distribution automation master station and communication.

[0003] The integration of primary and secondary circuits refers to the combination of primary and secondary circuits. The primary circuit is the main circuit, and the secondary circuit controls the primary circuit. The primary circuit is formed by the interconnection of electrical equipment that directly participates in the generation, transmission, transformation, and use of electrical energy. The secondary circuit is formed by the interconnection of equipment that protects, measures, controls, and measures the primary circuit equipment according to certain logical relationships.

[0004] In outdoor environments, circuit breakers are more prone to sudden failures due to natural conditions. Strong winds can cause utility poles to sway and tilt, and heavy rains can erode the foundation, leading to pole tilting. When these extreme situations occur, the structural stability of the utility pole is compromised, and its posture deforms. Existing integrated primary and secondary pole-mounted circuit breakers are often designed to rely on conventional electrical signals to trigger tripping. In extreme cases of physical deformation of the utility pole, they cannot actively disconnect the circuit. At this point, even if the utility pole has tilted or broken, the line may still be energized. If a suspended conductor or exposed metal part comes into contact with the ground or forms a conductive path, a pedestrian who accidentally approaches may be electrocuted, posing a safety hazard. Summary of the Invention

[0005] The purpose of this invention is to provide a primary and secondary integrated pole-mounted circuit breaker to solve the problem mentioned in the background art. The existing primary and secondary integrated pole-mounted circuit breakers are often designed to rely on conventional electrical signals to trigger the tripping. In extreme cases of physical deformation of the utility pole, they cannot actively cut off the circuit. At this time, even if the utility pole is tilted or even broken, the line may still be energized. Once the suspended wire or exposed metal parts come into contact with the ground or form a conductive path, if a pedestrian accidentally approaches, there is a high possibility of electric shock due to contact with the energized body, causing a safety hazard.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a primary and secondary integrated pole-mounted circuit breaker, comprising a mechanism box, several insulating cylinders fixed to the top of the mechanism box, and a support frame horizontally fixed to the inner wall of one side of the mechanism box. An indicator needle is rotatably mounted on one side of the mechanism box, and several lifting rings are fixed to one side of the top of the mechanism box. A limit groove is provided through the inside of the support frame, and an inclined triggering component is provided inside the limit groove. An insulating column is longitudinally slidably mounted through the middle of the bottom end of each of the several insulating cylinders. An adjustment component is provided at the bottom end of each insulating column. Two limit frames are symmetrically fixed on the bottom wall at both sides of the mechanism box, and a warning component is provided on the outside of one side of each of the two limit frames. The adjustment component includes an insulating threaded rod and a rotating seat. The insulating threaded rod is threadedly installed inside the insulating column, and the rotating seat is rotatably engaged with the outside of the top end of the insulating threaded rod.

[0007] Furthermore, a fixing frame is arranged laterally between the two limiting frames. Both ends of the fixing frame are longitudinally slidably engaged inside the corresponding limiting frame. A circuit breaking drive assembly is fixedly installed on the bottom wall of the mechanism box. A mounting frame is fixedly installed on the side of the fixing frame near each insulating post. The end of the mounting frame away from the fixing frame is fixedly installed on the outside of the bottom end of the corresponding insulating post. The output end of the circuit breaking drive assembly is fixedly installed on the outside of one side of the mounting frame.

[0008] Furthermore, the tilt triggering component includes a counterweight slider and a rack. The counterweight slider is slidably engaged inside the limiting groove. The rack is horizontally fixedly installed on the outside of the bottom side of the counterweight slider. Compression springs are fixedly installed on both sides of the counterweight slider. The ends of the compression springs away from the counterweight slider are embedded and fixedly installed on the inner wall of one side of the limiting groove.

[0009] Furthermore, a number of balls are equally spaced and rotatably mounted on the inner wall of the limiting slide groove. One side of each ball is in contact with the outer surface of the counterweight slider. The top of the counterweight slider is symmetrically provided with limiting holes. Each limiting hole is provided with an L-shaped positioning frame at its top. One end of each positioning frame is fixedly mounted on the outer side of the mounting frame.

[0010] Furthermore, each of the insulating cylinders has an arc-extinguishing chamber pre-installed inside its top end, a stationary contact is fixedly installed through the top end of the arc-extinguishing chamber, a terminal block is fixedly installed at the top end of the stationary contact, and a moving contact is fitted to the bottom end of the stationary contact.

[0011] Furthermore, the bottom end of the moving contact is fixedly installed on the outside of the top end of the rotating seat, and several guide rods are fixedly installed at equal angles around the bottom edge of the rotating seat. The bottom ends of the several guide rods are all slidably installed inside the top edge of the insulating column.

[0012] Furthermore, a buffer block is fixedly installed at the bottom end of the insulating threaded rod, and a gear is slidably installed through the outside of the insulating threaded rod near the buffer block, with one side of the gear meshing with one side of the rack.

[0013] Furthermore, the gear has several positioning grooves embedded at equal angles around its inner wall, and the insulating threaded rod has positioning strips fixedly installed on the outer side of the side near the positioning grooves. The positioning strips are longitudinally slidably connected to the positioning grooves.

[0014] Furthermore, the warning component includes a guide rod and an alarm. The guide rod is fixedly installed at one end of the rack, and the alarm is fixedly installed through and outside one side of the mechanism box. An auxiliary frame is fixedly installed on the outside of the limiting frame near the guide rod. A guide groove is opened through one side of the auxiliary frame. A guide slider is slidably engaged inside the guide groove. A columnar guide block is fixedly installed on the side of the guide slider near the guide rod.

[0015] Furthermore, a compression spring is fixedly connected between the outer side of one side of the guide slider and the inner wall of one side of the guide groove, and a wire is connected to the output end of one side of the guide slider, and the output end of the wire is electrically connected to the input end of the alarm.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the setting of the tilt trigger component and the adjustment component, and their coordinated operation, when the utility pole tilts due to extreme weather or external forces, this integrated primary and secondary pole-mounted circuit breaker can automatically separate the moving and stationary contacts, thereby achieving rapid power disconnection. This process requires no manual intervention and can cut off the circuit at the first moment of an emergency, fundamentally avoiding the risk of electric shock that pedestrians may encounter when approaching a tilted utility pole, and significantly improving the safety protection level of outdoor power distribution scenarios. At the same time, the tilt trigger component and the adjustment component can work together. This automatic triggering mechanism complements the original function of the circuit breaker, without affecting the circuit control during normal operation, and can quickly start protection in extreme situations, effectively reducing the possibility of fault expansion and providing dual protection for the safe operation of power distribution lines. 2. Through the setup of the tilt triggering component and the warning component, and their coordinated operation, when the utility pole tilts due to extreme weather or external forces, this integrated primary and secondary pole-mounted circuit breaker can automatically and quickly cut off the power and trigger the alarm in the warning component to sound an alarm. This continuous alarm signal promptly transmits a danger signal to nearby personnel, reminding them to stay away from the fault area and preventing unauthorized personnel from entering the dangerous situation. Simultaneously, the alarm signal provides maintenance personnel with clear fault location guidance, facilitating rapid response and repair, reducing the duration of the fault, and resulting in better overall performance.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 - Figure 8 A primary and secondary integrated pole-mounted circuit breaker includes a mechanism box 1, several insulating cylinders 2 fixed to the top of the mechanism box 1, and a support frame 5 horizontally fixed to the inner wall of one side of the mechanism box 1. An indicator needle 3 is rotatably installed on one side of the mechanism box 1. Several lifting rings 4 are fixed to one side of the top of the mechanism box 1. A limit groove 18 is provided through the inside of the support frame 5. An inclined triggering component is provided inside the limit groove 18. An insulating column 9 is slidably installed through the middle of the bottom end of each of the several insulating cylinders 2. An adjustment component is provided at the bottom end of each insulating column 9. Two limit frames 7 are symmetrically fixed on the bottom wall at both sides of the mechanism box 1. The adjustment component includes an insulating threaded rod 12 and a rotating seat 13. The insulating threaded rod 12 is threadedly installed inside the insulating column 9. The rotating seat 13 is rotatably engaged with the outside of the top end of the insulating threaded rod 12.

[0021] A fixing frame 8 is arranged horizontally between the two limiting frames 7. Both ends of the fixing frame 8 are longitudinally slidably engaged inside the corresponding limiting frame 7. A circuit breaking drive assembly 6 is fixedly installed on the bottom wall of the mechanism box 1. A mounting frame 11 is fixedly installed on the side of the fixing frame 8 near each insulating post 9. The end of the mounting frame 11 away from the fixing frame 8 is fixedly installed on the outside of the bottom end of the corresponding insulating post 9. The output end of the circuit breaking drive assembly 6 is fixedly installed on the outside of one side of the mounting frame 11.

[0022] The tilt triggering assembly includes a counterweight slider 19 and a rack 28. The counterweight slider 19 is slidably engaged inside the limiting groove 18. The rack 28 is horizontally fixedly installed on the outside of the bottom side of the counterweight slider 19. Compression springs 20 are fixedly installed on both sides of the counterweight slider 19. The ends of the compression springs 20 away from the counterweight slider 19 are embedded and fixedly installed on the inner wall of one side of the limiting groove 18.

[0023] Several balls 21 are evenly spaced and rotatedly engaged on the inner wall of the limiting slide groove 18. The outer side of one side of each ball 21 is in contact with the outer surface of one side of the counterweight slider 19. The top of the counterweight slider 19 is symmetrically provided with limiting holes 22. The top of each limiting hole 22 is provided with an L-shaped positioning frame 23. One end of each positioning frame 23 is fixedly installed on the outer side of one side of the mounting frame 11.

[0024] Each insulating cylinder 2 has an arc-extinguishing chamber 10 pre-installed inside its top end. A stationary contact 15 is fixedly installed through the top end of the arc-extinguishing chamber 10. A terminal block 17 is fixedly installed at the top end of the stationary contact 15. A moving contact 14 is attached to the bottom end of the stationary contact 15.

[0025] The bottom end of the moving contact 14 is fixedly installed on the outside of the top of the rotating seat 13. Several guide rods 16 are fixedly installed at equal angles around the bottom edge of the rotating seat 13. The bottom ends of the several guide rods 16 are all slidably installed inside the top edge of the insulating column 9.

[0026] A buffer block 27 is fixedly installed at the bottom end of the insulating threaded rod 12. A gear 24 is slidably installed through the side of the insulating threaded rod 12 near the buffer block 27. One side of the gear 24 meshes with one side of the rack 28.

[0027] The inner wall of the gear 24 is provided with several positioning grooves 25 at equal angles. The insulating threaded rod 12 is fixedly installed with positioning strips 26 on the outer side of the side near the positioning grooves 25. The positioning strips 26 and the positioning grooves 25 are longitudinally slidably connected.

[0028] In this embodiment, when the circuit breaker is installed and fixed on the utility pole by the lifting ring 4, the fixing angle of the mechanism box 1 needs to be adjusted in advance according to the risk characteristics of the installation environment (such as the prevailing wind direction, terrain subsidence trend, etc.) so that the extension direction of the limiting slide 18 is consistent with the high-risk direction of the utility pole that may tilt (such as the windward side, the slope side). After installation and fixing, the components in the mechanism box 1 are in the initial working state: the counterweight slider 19 is balanced in the limiting slide 18, the compression springs 20 on both sides are in the natural extension and contraction state, the ball 21 is in contact with the surface of the counterweight slider 19, the moving contact 14 is in close contact with the stationary contact 15, the guide rod 16 is stably inserted through the top of the insulating column 9, the insulating threaded rod 12 is connected to the insulating column 9 by threads, the gear 24 is sleeved on the outside of the insulating threaded rod 12 through the cooperation of the positioning groove 25 and the positioning strip 26, and is meshed with the rack 28. The end of the positioning frame 23 is suspended above the limiting hole 22.

[0029] When severe weather causes a utility pole to tilt, the counterweight slider 19 slides along the limiting groove 18 under gravity, compressing the compression spring 20 on the corresponding side. The ball bearing 21 moves with the slider to reduce friction, and the rack 28 moves synchronously with the counterweight slider 19, driving the meshing gear 24 to rotate. The gear 24 drives the insulating threaded rod 12 to rotate inside the insulating column 9 through the transmission action of the positioning groove 25 and the positioning bar 26. Due to the threaded engagement between the insulating threaded rod 12 and the insulating column 9, its rotation is converted into longitudinal movement, causing the rotating seat 13 at the top and the moving contact 14 to move downward along the guide rod 16, causing the moving contact 14 to separate from the stationary contact 15. The arc extinguishing chamber 10 then simultaneously extinguishes the arc, thereby achieving rapid power disconnection. This process requires no manual intervention and can cut off the circuit at the first moment of an emergency, fundamentally avoiding the risk of electric shock that pedestrians may encounter when approaching a tilted utility pole, and significantly improving the safety protection level of outdoor power distribution scenarios.

[0030] It should also be noted that when this integrated primary and secondary pole-mounted circuit breaker needs to be disassembled for maintenance or transport during normal use, the existing circuit breaker drive assembly 6 needs to be controlled to drive the fixed frame 8, insulating column 9 and mounting frame 11 to descend, thereby causing the moving contact 14 to disengage from the stationary contact 15, realizing power disconnection, which facilitates maintenance and transportation. At the same time, when the mounting frame 11 descends, it will drive the L-shaped positioning frame 23 on one side to descend synchronously, so that the positioning frame 23 is inserted into the limiting hole 22 at the bottom end, thereby limiting the counterweight slider 19. This ensures that the counterweight slider 19 will not wobble or shift during the disassembly, maintenance or transportation of the circuit breaker, effectively avoiding false triggering and ensuring the stability of the overall operation.

[0031] It should also be noted that after the tilting fault of the utility pole is resolved and it returns to an upright position, the circuit breaker can be reset to resume normal operation. At this time, the compression springs 20 on both sides of the counterweight slider 19 release their elastic potential energy, pushing the counterweight slider 19 to slide back to its initial equilibrium position along the limit groove 18. The rack 28 moves in the opposite direction simultaneously, driving the gear 24 meshing with it to reverse. The gear 24, through the cooperation of the positioning groove 25 and the positioning bar 26, drives the insulating threaded rod 12 to rotate in the opposite direction within the insulating column 9. Its rotational motion is converted into longitudinal upward motion. This causes the rotating seat 13 and the moving contact 14 to move upward along the guide rod 16 until the moving contact 14 and the stationary contact 15 are tightly fitted again. If the circuit breaker was previously under maintenance, the circuit breaker drive assembly 6 needs to be controlled to drive the fixed frame 8, the insulating column 9 and the mounting frame 11 to rise. The mounting frame 11 simultaneously drives the L-shaped positioning frame 23 to move upward, so that the positioning frame 23 is pulled out from the limiting hole 22, releasing the limit on the counterweight slider 19. At this point, all components return to their initial working state, and the arc-extinguishing chamber 10, the terminal block 17 and other components return to normal function. The circuit breaker can be put back into operation.

[0032] Example 2: Please refer to Figure 9 - Figure 11 This embodiment further illustrates Example 1, with warning components provided on the outer side of one side of each of the two limit frames 7.

[0033] The warning assembly includes a guide rod 29 and an alarm 36. The guide rod 29 is fixedly installed at one end of the rack 28. The alarm 36 is fixedly installed through the outside of one side of the mechanism box 1. An auxiliary frame 30 is fixedly installed on the outside of the limit frame 7 near the guide rod 29. A guide groove 31 is opened through the inside of one side of the auxiliary frame 30. A guide slider 32 is slidably engaged inside the guide groove 31. A columnar guide block 33 is fixedly installed on the side of the guide slider 32 near the guide rod 29.

[0034] A compression spring 34 is fixedly installed between the outer side of the guide slider 32 and the inner wall of the guide groove 31. A wire 35 is connected to the output end of the guide slider 32, and the output end of the wire 35 is electrically connected to the input end of the alarm 36.

[0035] Specifically, the design of the columnar conductive block 33 and the compression spring 34 ensures the reliability of the contact between the conductive rod 29 and the conductive block 33. Even under vibration or tilting conditions, a stable conductive path can be formed to ensure the effective activation of the alarm 36. It does not rely on complex electronic control, has strong anti-interference ability, and is suitable for harsh outdoor environments.

[0036] In this embodiment, when severe weather causes the utility pole to tilt, the counterweight slider 19 in the tilt trigger assembly slides within the limiting groove 18, causing the rack 28 to move synchronously. Simultaneously, as the trigger adjustment assembly separates the moving contact 14 from the stationary contact 15 to cut off power, the conductive rod 29 at one end of the rack 28 moves with it and contacts the conductive block 33 on the guide slider 32, pushing the guide slider 32 to slide within the guide groove 31 of the auxiliary frame 30, compressing the compression spring 34 on one side. At this time, the guide slider 32 forms a conductive path with the alarm 36 through the wire 35, activating the alarm 36 fixed outside the mechanism box 1. This continuous warning from the alarm 36 promptly transmits danger signals to surrounding personnel, reminding them to stay away from the fault area and preventing unauthorized personnel from entering the dangerous situation. Simultaneously, the alarm signal provides maintenance personnel with clear fault location guidance, facilitating rapid response and repair, reducing the duration of the fault, and resulting in better overall performance.

[0037] When the tilting fault of the utility pole is resolved and it returns to an upright position, the warning component resets synchronously with the overall structure. At this time, the counterweight slider 19 in the tilt trigger component slides in the opposite direction along the limiting groove 18 under the action of the compression spring 20, causing the rack 28 to return to its initial position. The conducting rod 29 at one end of the rack 28 then disengages from the conducting block 33 on the guide slider 32. Under the action of the elastic potential energy of the compression spring 34, the guide slider 32 slides in the opposite direction along the guide groove 31 of the auxiliary frame 30 to its initial position, completely separating the conducting block 33 from the conducting rod 29, thereby cutting off the conductive path formed by the guide slider 32 through the wire 35 and the alarm 36, and the alarm 36 stops sounding. At this point, all components of the warning component have returned to their initial state, awaiting the next emergency trigger.
