Description

Technical Field

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

[0002] Primary and secondary circuit breaker integration refers to the integrated design of primary circuits (the main circuit, which is formed by interconnecting electrical equipment directly involved in the generation, transmission, transformation, and use of electrical energy) and secondary circuits (the circuit formed by interconnecting equipment that protects, measures, controls, and meters the primary circuit equipment according to a certain logical relationship), achieving a high degree of unity and coordination in function and structure. Primary and secondary integrated pole-mounted circuit breakers are circuit breaker products designed based on this concept and are widely used in the segmentation and interconnection of 10kV distribution network backbone lines.

[0003] During use, complete pole-mounted circuit breakers are usually installed at high altitudes. In strong winds, the equipment generates high-frequency micro-vibrations, which accelerate the cracking of solder joints or component detachment of internal electronic components (such as sensors and circuit boards). In addition, the sealed enclosure contains multiple heat-generating components such as the circuit breaker operating mechanism (heat source), electronic sensors, FTU board, communication module, and backup power supply (such as lithium battery). In high-temperature environments (especially under direct sunlight in summer), the internal temperature may exceed the allowable operating temperature of electronic components (such as electrolytic capacitors and chips) (>85℃), leading to performance degradation, shortened lifespan, or even failure. Summary of the Invention

[0004] The purpose of this invention is to address the problems that, during the use of complete pole-mounted circuit breakers, high-frequency micro-vibrations generated by the equipment in strong wind environments accelerate the cracking of solder joints or component detachment of internal electronic components (such as sensors and circuit boards). In addition, the sealed enclosure contains multiple heat-generating components of the circuit breaker, and in high-temperature environments, the internal temperature may exceed the allowable operating temperature of the electronic components, leading to performance degradation, shortened lifespan, or even failure.

[0010] Multiple heat-conducting plates are fixed on both sides of the sealed box, and a shock-absorbing plate is fixed between the bottom wall of the inner cavity of the sealed box and the heat dissipation box.

[0012] The drive assembly includes a bracket plate fixedly connected to a fixed ring, an electric telescopic rod fixed to one side of the bracket plate, and a loop block fixed to the output end of the electric telescopic rod.

[0013] As a further description of the above-mentioned technology, a primary and secondary integrated pole-mounted circuit breaker is as follows:

[0014] The fixed ring has a sliding groove, and a groove block is slidably installed in the inner cavity of the sliding groove through the mounting block. One end of the groove block is rotatably connected to the rotating ring, and a fixed shaft that matches the inner cavity of the groove block is fixed in the inner cavity of the groove block.

[0015] As a further description of the above-mentioned technology, a primary and secondary integrated pole-mounted circuit breaker is as follows:

[0016] The adjusting component includes a sliding block, a slider adapted to a sliding groove is fixed on one side of the sliding block, a sliding column adapted to a limiting groove is fixed on one side of the sliding block, and a spiral exhaust groove is opened on one side of the inclined surface of the sliding block.

[0017] As a further description of the above-mentioned technology, a primary and secondary integrated pole-mounted circuit breaker is as follows:

[0018] The sliding block has an air vent inside, and multiple annular arrays of telescopic grooves are formed around the air vent on the sliding block. Each of the multiple telescopic grooves has a sliding rod slidably installed inside. One end of each of the multiple sliding rods is fixed with a circular plate. Each of the multiple telescopic grooves has a negative pressure spring connected to the circular plate. A connecting rod is fixed to one side of the circular plate, and a blocking block is fixed to one end of the connecting rod.

[0019] As a further description of the above-mentioned technology, a primary and secondary integrated pole-mounted circuit breaker is as follows:

[0020] The bottom wall of the heat dissipation box is provided with two sets of connecting components that are adapted to the first bevel gear.

[0021] As a further description of the above-mentioned technology, a primary and secondary integrated pole-mounted circuit breaker is as follows:

[0022] A set of vane assemblies is installed on both sides of the heat sink. Each vane assembly includes a connecting shaft that is rotatably mounted through the heat sink. The connecting shaft and the heat sink are connected by a torsion spring. A guide vane is fixed to one end of the connecting shaft, and a connecting block is fixed to the other end of the connecting shaft. An insulating rope passes through both ends of the connecting block in sequence.

[0023] In summary, due to the adoption of the above-mentioned technology in a primary and secondary integrated pole-mounted circuit breaker, the beneficial effects of this invention are:

[0024] 1. Through the cooperation of heat dissipation pipe one, adjustable components and heat dissipation pipe two, not only can the throat area formed by the multiple adjustable components be reduced by adjusting multiple adjustable components to suppress vortex oscillation and reduce vibration, but also when the temperature is too high, the throat area formed by the multiple adjustable components can be expanded by adjusting multiple adjustable components to enhance heat dissipation. The airflow serves as both a heat dissipation medium and disrupts vortex street formation through a specific structural design; heat dissipation pipe one, adjustable components and heat dissipation pipe two form a venturi tube, and the air outlet channel between the multiple adjustable components is the throat of the venturi tube.

[0025] 2. This device can adjust the pressure of the air outlet channel composed of multiple adjustment components through its adjustable components, preventing a sudden drop in throat pressure under high-speed wind conditions. When the pressure drops suddenly, it automatically releases pressure to prevent structural damage and thus device failure. Through the movable disc and connecting rod, when the throat pressure drops suddenly, the block retracts into the air outlet, leaving a gap between the block and the air outlet. At the same time, the disc moves, no longer blocking one end of the air outlet, allowing gas to be released, relieving the throat pressure and bringing it back to normal. Then, under the action of multiple negative pressure springs, the disc and block are reset.

[0026] 3. Through the coordinated operation of the spiral frame, bevel gear, connecting components, and vane assembly, this device can automatically adjust the angle of attack of the guide vanes according to the wind speed, thereby more effectively guiding the airflow, reducing the drag coefficient, and thus reducing wind-induced vibration. At the same time, it can disrupt the alternating vortex street formed by the airflow leaving the rectangular box at the back, reducing vibration and making the internal electronic components less prone to damage, thus extending the service life of the device. Two sets of one-way bearings achieve reverse wind locking and downwind drive. Attached Figure Description

[0048] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a primary and secondary integrated pole-mounted circuit breaker according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] like Figures 1-4 As shown, a primary and secondary integrated pole-mounted circuit breaker includes a heat dissipation box 10 and a sealing box 11. The sealing box 11 is fixed to the inner cavity of the heat dissipation box 10, forming a double-layer mounting box. The circuit breaker body 13 is fixed in the inner cavity of the sealing box 11. The gap between the sealing box 11 and the heat dissipation box 10 is used for heat dissipation and to reduce the impact of wind vibration. The sealing box 11 is used to seal the circuit breaker body 13 to prevent the circuit breaker body 13 from being damaged by external influences.

[0051] Next, two symmetrical heat dissipation pipes 20 and 40 are fixed on both sides of the inner cavity of the heat dissipation box 10. The inner cavities of heat dissipation pipes 20 and 40 are equipped with wind speed sensors and temperature sensors to control the opening and closing of the adjustable component 30. Both heat dissipation pipes 20 and 40 are made of a section of tapered tube and a section of round tube. The adjustable component 30 is fixed between heat dissipation pipes 20 and 40 on the same side. The inner cavities of heat dissipation pipes 20, adjustable component 30 and heat dissipation pipe 40 are connected to form a venturi tube. No matter which side the wind blows from, it can pass through the venturi tube formed by heat dissipation pipes 20, adjustable component 30 and heat dissipation pipe 40, thereby cooling the inner cavity of the heat dissipation box 10 and breaking the vortex street formation.

[0052] Also, such as Figure 4 As shown, both the first heat sink 20 and the second heat sink 40 on the same side have a spiral bracket 21 rotatably mounted inside their cavities. Wind can cause the spiral bracket 21 to rotate. Wind blowing from the first heat sink 20 side causes the spiral bracket 21 inside the first heat sink 20 to rotate, and wind blowing from the second heat sink 40 side causes the spiral bracket 21 inside the second heat sink 40 to rotate. A coaxial bevel gear 22 is fixed to one side of the spiral bracket 21 via a one-way bearing. The one-way bearings on the spiral bracket 21 inside the first heat sink 20 and the second heat sink 40 are installed in different directions. When the spiral bracket 21 inside the first heat sink 20 rotates with the bevel gear 22, the spiral bracket 21 inside the second heat sink 40 causes the bevel gear 22 to rotate freely. When the spiral bracket 21 inside the second heat sink 40 rotates with the bevel gear 22, the spiral bracket 21 inside the first heat sink 20 causes the bevel gear 22 to rotate freely. The two sets of one-way bearings achieve reverse wind locking and forward wind driving.

[0053] Among them, such as Figure 3 As shown, the bottom wall of the inner cavity of the heat sink 10 is provided with two sets of connecting parts 50 that are adapted to the bevel gear 22. A set of vane assemblies 60 are installed on both sides of the heat sink 10. There are multiple vane assemblies 60. They are connected to the propeller frame 21 through the connecting parts 50 and the bevel gear 22. When the wind blows, the angle of attack of multiple vane assemblies 60 can be adjusted according to the change of wind speed, so as to guide the air more effectively, reduce the drag coefficient, and reduce wind-induced vibration.

[0054] Next, as Figure 3 As shown, multiple heat-conducting plates 12 are fixed on both sides of the sealed box 11. The heat-conducting plates 12 are used to conduct heat out of the inner cavity of the sealed box 11, so that it can be carried away by the airflow. A damping plate 14 is fixed between the bottom wall of the inner cavity of the sealed box 11 and the heat sink 10. The damping plate 14 is a phase change material and plays the role of heat absorption and vibration damping.

[0055] Furthermore, such as Figures 5-7As shown, the adjustable component 30 includes a fixed ring 31 fixedly connected to the heat sink 40. The inner cavity of the fixed ring 31 communicates with the inner cavity of the heat sink 40. A rotating ring 33 is rotatably mounted on the fixed ring 31. A plurality of ring array limiting grooves 34 are provided on one side of the rotating ring 33. A driving component 32 for driving the rotating ring 33 to rotate is mounted on the fixed ring 31. The driving component 32 is used to make the rotating ring 33 rotate around the center of the fixed ring 31.

[0056] Next, the adjustable component 30 also includes a mounting ring 37 fixedly connected to the heat sink 20. The inner cavity of the mounting ring 37 communicates with the inner cavity of the heat sink 20. A plurality of annularly arranged sliding grooves 38 are provided on one side of the mounting ring 37. A fixing tube 36 adapted to the rotating ring 33 is fixed to the outer surface of the mounting ring 37. A plurality of annularly arranged adjusting components 35 are provided between the rotating ring 33 and the mounting ring 37. The plurality of annularly arranged adjusting components 35 slide between the rotating ring 33 and the mounting ring 37. Figure 9 As shown, the adjustable component 30, heat dissipation pipe 20 and heat dissipation pipe 40 form a venturi tube, and multiple adjusting components 35 form an annular channel through circumferential linkage, which is equivalent to the throat of the venturi tube. Through Bernoulli's principle, the airflow can dissipate heat on the circuit breaker body 13.

[0057] By rotating the ring 33 and fixing the fixing tube 36 on the outside of the mounting ring 37, the limiting groove 34 is not only used to limit the displacement of the adjusting component 35, but also to discharge the gas released by the adjusting component 35, thereby reducing the pressure on the multiple adjusting components 35 and reducing the probability of damage to the adjustable component 30.

[0058] By moving multiple adjustable components 35, the throat area increases to 200% when the temperature is too high, enhancing the heat dissipation effect. When the wind speed exceeds a certain value, the throat area shrinks to 40% of the heat dissipation pipe area, suppressing vortex vibration.

[0059] By sliding multiple adjusting components 35 between the rotating ring 33 and the mounting ring 37, the multiple adjusting components 35 form an adjustable throat, such as... Figure 9 and Figure 10 As shown.

[0060] Furthermore, such as Figure 8 As shown, the drive assembly 32 includes a bracket plate 321 fixedly connected to the fixed ring 31, an electric telescopic rod 322 fixed on one side of the bracket plate 321, and a loop block 323 fixed at the output end of the electric telescopic rod 322.

[0061] Next, a groove is provided on the fixed ring 31, with the fixed ring 31 as the center. A groove block 325 is slidably installed in the inner cavity of the groove through the mounting block. One end of the groove block 325 is rotatably connected to the rotating ring 33. The groove block 325 swings in the inner cavity of the groove about the center of the fixed ring 31 through the mounting block. A fixed shaft 324 that matches the inner cavity of the herringbone block 323 is fixed in the inner cavity of the groove block 325. As the herringbone block 323 moves with the output end of the electric telescopic rod 322, the fixed shaft 324 slides in the inner cavity of the herringbone block 323, thereby causing the groove block 325 to swing with the rotating ring 33 about the center of the fixed ring 31.

[0062] Furthermore, such as Figure 11 and Figure 12 As shown, the adjusting component 35 includes a sliding block 351. A slider 352 adapted to the sliding groove 38 is fixed on one side of the sliding block 351, and a sliding column 353 adapted to the limiting groove 34 is fixed on one side of the sliding block 351. By rotating the rotating ring 33, the limiting groove 34 and the sliding column 353 are engaged, so that the slider 352 slides along the sliding groove 38, thereby achieving the purpose of adjusting the adjusting component 35. The multiple adjusted sliding blocks 351 form an air outlet channel. This air outlet channel is engaged with the heat sink 20 and the heat sink 40. This air outlet channel is equivalent to the throat of the venturi tube. Therefore, the "adjustable throat" can control the size of the venturi tube throat, thereby achieving the purpose of enhancing heat dissipation and suppressing vortex vibration.

[0063] Among them, a spiral exhaust groove 354 is provided on one side of the inclined surface of the sliding block 351. The combination of multiple exhaust grooves 354 can reduce the probability of vortex vibration generated by the "adjustable throat" and disrupt the boundary layer separation.

[0064] Next, an air vent is provided inside the sliding block 351, and the air vent passes through the sliding block 351. Multiple annular array telescopic grooves 355 are provided around the air vent on the sliding block 351. Each telescopic groove 355 is composed of two interconnected cylindrical grooves. A sliding rod 356 is slidably installed in the inner cavity of each telescopic groove 355. The sliding rod 356 can slide in the inner cavity of the lower cylindrical groove. A circular piece 358 is fixed to one end of each sliding rod 356. A negative pressure spring 357 connected to the circular piece 358 is fixed in the inner cavity of each telescopic groove 355. The negative pressure spring 357 will deform under a certain pressure. A connecting rod 359 is fixed to one side of the circular piece 358. A blocking block 360 is fixed to one end of the connecting rod 359. The connecting rod 359 is located in the inner cavity of the air vent. The blocking block 360 is used to block one end of the air vent, and the circular piece 358 is used to block the other end of the air vent.

[0065] Under normal conditions, the sliding groove 38 will not shift under the action of the negative pressure spring 357. When the pressure of the "adjustable throat" composed of multiple adjusting components 35 is too high, in order to avoid damage to the device, the block 360 will move into the inner cavity of the vent under the pressure. Then, after passing through a section of the vent that is adapted to the block 360, there is a certain gap between the block 360 and the side wall of the vent, and the gas can be discharged from the vent, thereby reducing the pressure of the "adjustable throat" and avoiding the problem of device damage due to excessive pressure.

[0066] Example 2

[0067] This embodiment further defines the connecting component 50 and the blade assembly 60 based on Embodiment 1, in order to achieve the purpose of adjusting the angle of attack of the guide blade 62 according to the wind speed.

[0068] Specifically, such as Figure 13 As shown, the connecting component 50 includes a vertical plate 51 fixed to the bottom wall of the inner cavity of the sealing box 11. A connecting shaft 52 is rotatably mounted on the vertical plate 51. One end of the connecting shaft 52 is fixed with a bevel gear 53 that meshes with a bevel gear 22. When the bevel gear 22 rotates, the bevel gear 53 can rotate. The other end of the connecting shaft 52 is fixed with a winding wheel 54. The winding wheel 54 rotates by the bevel gear 53 driving the connecting shaft 52. The two winding wheels 54 on the same side are fixedly connected to an insulating rope 55. A set of connecting components 50 consists of two connecting components 50 on the same side, so there are two winding wheels 54 on the same side.

[0069] Furthermore, such as Figure 14 As shown, the vane assembly 60 includes a connecting shaft 61 that is rotatably mounted on the heat sink 10. The connecting shaft 61 and the heat sink 10 are connected by a torsion spring. One end of the connecting shaft 61 is fixed with a guide vane 62. Through the connection of the torsion spring, the guide vane 62 connected to the connecting shaft 61 is horizontal in the normal state. The other end of the connecting shaft 61 is fixed with a connecting block 63. An insulating rope 55 passes through both ends of the connecting block 63 in sequence. Therefore, the insulating rope 55 can make multiple connecting blocks 63 tilt to the same side, so that multiple guide vanes 62 tilt to one side under the action of the connecting block 63, thereby achieving the purpose of adjusting the angle of attack of the guide vane 62.

[0070] Through the action of the spiral frame 21 and the bevel gear 22, the blade assembly 60 can adjust the tilt angle according to the wind speed.

[0071] It should be noted that the heat-conducting plate 12, circuit breaker body 13, damping plate 14, spiral frame 21, electric telescopic rod 322, winding wheel 54 and insulating rope 55 in this invention are all existing technologies, and their installation methods and control methods are also conventional designs, which will not be described in detail in this invention.

[0072] The working principle of this invention: Through the cooperation between the heat dissipation pipe 20, the adjustable component 30 and the heat dissipation pipe 40, this device can not only reduce the throat area formed by the multiple adjusting components 35 by adjusting the multiple adjusting components 35, thereby suppressing vortex oscillation and reducing vibration, but also expand the throat area formed by the multiple adjusting components 35 when the temperature is too high, thereby enhancing heat dissipation. The airflow serves as both a heat dissipation medium and, through a specific structural design, disrupts the formation of vortex streets.

[0073] A venturi tube is formed by heat dissipation pipe 20, adjustable component 30, and heat dissipation pipe 40. The air outlet between the multiple adjusting components 35 is the throat of the venturi tube. Sensors inside the heat dissipation pipes 20 and 40 cause the electric telescopic rod 322 to receive signals, such as... Figure 9 and Figure 10 As shown, the output end of the electric telescopic rod 322 moves the loop block 323. Through the cooperation between the loop block 323 and the fixed shaft 324, the groove block 325 swings around the center of the fixed ring 31 with the rotating ring 33. This causes the limiting groove 34 on the rotating ring 33 to push multiple sliding columns 353, and multiple sliding blocks 351 slide with the slider 352 in the inner cavity of the matching sliding groove 38. This adjusts the area of ​​the air outlet channel between the multiple sliding blocks 351. By adjusting the area of ​​the throat, the purpose of suppressing vortex vibration, reducing vibration, or enhancing heat dissipation can be achieved.

[0074] This device can adjust the pressure of the air outlet channel composed of multiple adjustment components 35 by setting the adjustment component 35, so as to prevent the throat pressure from dropping suddenly under high-speed wind conditions, thereby causing damage to the device.

[0075] With the movable disc 358 and connecting rod 359, when the throat pressure drops suddenly, the block 360 retracts into the vent, leaving a gap between the block 360 and the vent. At the same time, the disc 358 moves and no longer blocks one end of the vent, allowing the gas to be released, relieving the throat pressure and bringing the throat pressure back to normal. Then, under the action of multiple negative pressure springs 357, the disc 358 and the block 360 are reset.

[0076] This device, through the cooperation between the spiral frame 21, bevel gear 22, connecting component 50 and vane assembly 60, can automatically adjust the angle of attack of the guide vane 62 according to the wind speed, thereby more effectively guiding the airflow, reducing the drag coefficient, and thus reducing wind-induced vibration. At the same time, it can disrupt the alternating vortex street formed when the airflow bypasses the rectangular box and forms vortices at the back, reducing vibration, making the electronic components inside the device less prone to damage, and extending the service life of the device.

[0077] During use, both heat sink 20 and heat sink 40 have rotating screw frames 21 installed inside their cavities. The one-way bearings on the screw frames 21 inside the heat sink 20 and heat sink 40 are installed in different directions. When the screw frame 21 inside the heat sink 20 rotates with bevel gear 22, bevel gear 22 rotates with bevel gear 53, which in turn causes the connecting shaft 52 to rotate with the winding wheel 54. The winding wheel 54 winds up the insulating rope 55. Since the insulating rope 55 passes through both ends of the connecting block 63 in sequence, the insulating rope 55 can tilt the connecting block 63 to one side, which in turn causes the guide vane 62 to tilt to one side. The wind blows from one side of the heat sink 20 to the guide vane 62. The side of the guide vane 62 closest to the heat sink 40 tilts downward, which increases the angle of attack of the guide vane 62. This can guide the air more effectively, reduce the wind resistance coefficient, reduce wind-induced vibration, and extend the service life of the device.

[0078] Next, the other end of the insulating rope 55 rotates with another winding wheel 54, causing the bevel gear 23 and the bevel gear 22 connected to the spiral frame 21 inside the heat sink 40 to rotate freely through the coupling 52.

[0079] Similarly, when the spiral bracket 21 inside the heat pipe 40 rotates with the bevel gear 22, the guide vane 62 tilts downward on the side closest to the heat pipe 20. When wind blows from different directions, the guide vane 62 can adjust its tilt direction according to the direction and strength of the wind, thereby eliminating the influence of airflow from different directions.

[0080] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technology of the present invention and the inventive concept of the primary and secondary integrated pole-mounted circuit breaker, should be covered within the scope of protection of the present invention.
