Description

Technical Field

[0001] This invention mainly relates to the technical field of circuit breakers, specifically to the anti-condensation pole structure of a primary and secondary integrated circuit breaker. Background Technology

[0002] The integrated primary and secondary circuit breaker is a core power protection and control device in modern intelligent power distribution network systems. It is widely used in the transformation and construction of urban and rural power grids. When the ambient temperature drops rapidly, the water vapor inside the pole is easily saturated and condenses on the inner wall of the pole, the secondary terminal block and other components. Condensation will reduce the insulation performance inside the pole, cause surface flashover and short circuit faults, corrode internal metal components, affect secondary signal transmission, threaten the reliability of circuit breaker operation and shorten the service life of the equipment.

[0003] An existing anti-condensation device for a pole-mounted circuit breaker includes a circuit breaker housing, a mounting base on one side of the circuit breaker housing, an anti-condensation cover fixedly connected to the mounting base by bolts, a mounting plate inside the anti-condensation cover, an environmentally friendly insulating gas cylinder inside the anti-condensation cover, the environmentally friendly insulating gas cylinder being fixedly connected to the outer wall of one side of the mounting plate, an electromagnetic one-way valve being fixedly connected to one side of the mounting plate, the electromagnetic one-way valve being connected to the environmentally friendly insulating gas cylinder via a pipeline, and the electromagnetic one-way valve being connected to the circuit breaker housing via a pipeline.

[0004] While the aforementioned technologies can intelligently dry and replenish, extending maintenance cycles, and feature an externally mounted anti-condensation device for convenient maintenance, they can only perform drying processes and are not convenient for removing condensation that forms on the inner wall of the electrode. This results in low drying efficiency, and the condensate is difficult to collect and remove, easily re-condensing inside the electrode, making it difficult to achieve the desired anti-condensation effect. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an anti-condensation pole structure for a primary and secondary integrated circuit breaker, so as to solve the technical problems mentioned in the background art.

All three poles are fixedly mounted on the upper surface of the housing. A mounting plate is fixed to each pole at the top inner surface of the housing. An installation cavity is formed inside the mounting plate below the pole. A second through hole communicating with the installation cavity is formed on the upper surface of the mounting plate, and a first through hole communicating with the installation cavity is formed on the lower surface of the mounting plate. An anti-condensation component is provided in the installation cavity. This anti-condensation component is used to scrape and absorb condensation generated on the inner wall of the pole by reciprocating rotation. A driving cavity is formed inside the mounting plate on one side of the installation cavity. A transmission component is provided inside the driving cavity to drive the anti-condensation component to reciprocate within the installation cavity.

[0007] Specifically, the anti-condensation component includes an annular plate, which is rotatably installed inside the mounting cavity. A vertical scraper is fixed on the upper surface of the annular plate. The scraper is located inside the pole post, and the side wall of the scraper contacts the inner wall of the pole post. A sponge strip is embedded at the center line of the side wall where the scraper contacts the inner wall of the pole post. The outer wall of the annular plate is provided with inner teeth.

[0008] Specifically, in this technical solution, an annular slide rail is fixed on the upper surface of the annular plate near the outer edge, and a matching slide groove is provided on the top wall of the mounting cavity at the slide rail.

[0009] Specifically, the annular plate has multiple liquid permeation holes, the inner wall of the mounting cavity has an annular guide groove, the multiple liquid permeation holes are all located above the guide groove, the lower surface of the mounting plate is connected to a liquid guide pipe at the guide groove, the bottom end of the liquid guide pipe penetrates the wall of the box and connects to a collection box, the collection box is installed on the wall of the box by screws, and the inside of the collection box is filled with absorbent cotton.

[0010] Specifically, in this technical solution, the transmission assembly includes a vertical shaft, which is rotatably mounted in the drive cavity. A drive gear and a worm gear are fixed on the outer wall of the shaft from top to bottom. The diameter of the drive gear is larger than the diameter of the worm gear. The drive cavity and the mounting cavity are connected by a through groove. One side of the tooth surface of the drive gear passes through the through groove and meshes with the inner tooth set in the anti-condensation assembly.

[0011] Specifically, in this technical solution, a horizontal worm is provided inside the drive cavity on one side of the worm wheel. The worm meshes with the worm wheel. A fixing plate is fixed inside the drive cavity at one end of the worm. One end of the worm is rotatably mounted on the fixing plate. A connecting shaft is fixed at the other end of the worm. The connecting shaft extends through the mounting plate into the protective shell and is fixed with a shaft block. The diameter of the shaft block is larger than the diameter of the connecting shaft.

[0012] Specifically, in this technical solution, a transmission wheel is fixedly installed on the outer wall of the shaft block, and the corresponding transmission wheels in the three transmission components are connected by a transmission chain. A reciprocating motor is installed on the inner wall of the protective shell by screws, and the output end of the reciprocating motor is connected to the end flange of one of the shaft blocks.

[0013] Specifically, in this technical solution, the reciprocating motor is electrically connected to the primary and secondary integrated control terminal of the circuit breaker body.

[0016] In summary, the present invention has the following beneficial effects: the annular plate drives the scraper to rotate back and forth, and the sponge strip on the side wall of the scraper can completely scrape off and absorb the residual condensation, preventing condensation from adhering to the inner wall of the pole and the surface of the secondary wiring terminals. The scraped condensation moves down along the inner wall and is collected in the collection box through the liquid permeation hole, guide groove and liquid guide pipe. It is then stabilized and absorbed by the absorbent cotton, preventing the condensation from re-condensing inside the pole, effectively improving the anti-condensation efficiency, significantly reducing the risk of pole insulation performance degradation, surface flashover and short circuit faults caused by condensation, preventing condensation from corroding internal metal parts, ensuring stable secondary signal transmission, extending the service life of the circuit breaker, and improving operational reliability. Furthermore, through the coordinated operation of the worm gear, worm wheel, transmission wheel, and transmission chain, the anti-condensation components corresponding to the three poles can be synchronously rotated back and forth. This ensures the consistency of the anti-condensation operation of the three poles and simplifies the overall drive structure. During the reciprocating rotation of the scraper to remove condensation, it also cleans the dust adhering to the inner wall of the pole, preventing dust accumulation from further affecting the insulation performance of the pole, indirectly improving the external insulation level of the pole, and extending the maintenance cycle of the pole.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described.

[0021] It should be noted that an anti-condensation cover using existing technology can also be installed on the side wall of the housing 101. The internal equipment of the cover is mainly used to effectively dehumidify the inside of the housing 101, thereby working in conjunction with this device to significantly improve the overall anti-condensation effect.

[0022] In this embodiment, please refer to Figure 1 - Figure 7As shown, the anti-condensation pole structure of the primary and secondary integrated circuit breaker includes a circuit breaker body 1. The circuit breaker body 1 serves as the installation foundation and core working component of the entire device. The circuit breaker body 1 consists of a housing 101 and three poles 102. All three poles 102 are fixedly installed on the upper surface of the housing 101, and the connection between the poles 102 and the housing 101 is sealed and potted to prevent external moisture from entering the interior of the poles 102. The housing 101 is made of cold-rolled steel sheet, stamped and formed, with a surface coated with an anti-corrosion and anti-rust coating, possessing good structural strength and... With resistance to outdoor environmental corrosion, all three poles 102 are made of epoxy resin and integrated with high-voltage contacts, arc-extinguishing chambers and secondary sensors. The inner walls are smooth and have excellent insulation properties, avoiding condensation residue caused by rough inner walls. The bottom of both sides of the box 101 are integrally fixed with ear plates 104. Both ear plates 104 are provided with screw holes for fixing. The inner walls of the screw holes are provided with internal threads, which makes it easy to fix the entire circuit breaker body 1 to the pole mounting bracket with bolts, so as to achieve stable installation of the device and adapt to outdoor pole mounting scenarios. Mounting plates 2 are fixed to the top of the inner part of the housing 101 at the pole 102. The mounting plates 2 are made of high-strength insulating epoxy resin to prevent its conductivity from affecting the electrical performance inside the pole 102. They also have good structural rigidity and are used to install the anti-condensation component 3 and the transmission component 6. The mounting plate 2 has a mounting cavity 202 inside the pole 102. The upper surface of the mounting plate 2 has a second through hole 2021 communicating with the mounting cavity 202. The lower surface of the mounting plate 2 has a first through hole 201 communicating with the mounting cavity 202. The second through hole 2021, the mounting cavity 202 and the first through hole 201 form a through cavity that passes through the mounting plate 2, so that the secondary leads and electrical connectors inside the pole 102 can pass through, so as to realize the connection between the pole 102 and the electrical components inside the housing 101. The mounting cavity 202 is equipped with an anti-condensation component 3. This component 3 is used to reciprocate and rotate to scrape and absorb condensation generated on the inner wall of the pole post 102, preventing condensation from adhering to the inner wall of the pole post 102 and the surface of the internal secondary wiring terminals. The anti-condensation component 3 includes an annular plate 301, which is made of insulating plastic. Its outer diameter matches the inner diameter of the mounting cavity 202. The annular plate 301 is rotatably installed inside the mounting cavity 202. A vertical scraper 304 is fixed to the upper surface of the annular plate 301. The scraper 304 is made of high-strength insulating plastic, and its length matches the height of the inner wall of the pole post 102. The scraper 304 is located inside the pole post 102, and its sidewall contacts the inner wall of the pole post 102. A sponge strip is embedded in the center line. The sponge strip is made of waterproof, mildew-proof, and hydrophilic sponge. It is easy to disassemble and replace later through the embedded method of the slot. It works with the scraper 304 to first scrape off the condensation and then absorb the residual moisture. The outer wall of the annular plate 301 is provided with inner teeth 302. The upper surface of the annular plate 301 is fixed with an annular slide rail 305 near the outer edge. The slide rail 305 is made of wear-resistant plastic. The top wall of the mounting cavity 202 is provided with a matching slide groove at the slide rail 305. The slide rail 305 slides and engages in the slide groove to form a sliding fit. It is used to guide and limit the rotation of the annular plate 301, ensuring that the annular plate 301 rotates smoothly back and forth in the mounting cavity 202, avoiding deviation and jamming, and enhancing the stability of the annular plate 301 when rotating. Inside the mounting plate 2, on one side of the mounting cavity 202, there is a drive cavity 203. Inside the drive cavity 203 is a transmission assembly 6, which drives the anti-condensation assembly 3 to reciprocate within the mounting cavity 202. The transmission assembly 6 includes a vertical shaft 602 made of stainless steel, possessing good wear resistance and rigidity. The shaft 602 is rotatably mounted in the drive cavity 203, and bearings are embedded in the upper and lower walls of the drive cavity 203 to ensure smooth and non-deviation-free rotation of the shaft 602. From top to bottom, the outer wall of the shaft 602 is fixed with a drive gear 601 and a worm gear 603. The diameter of the drive gear 601 is larger than the diameter of the worm gear 603, achieving speed reduction transmission. To ensure the anti-condensation component 3 can rotate smoothly at low speed and avoid damage to the inner wall of the pole post 102 caused by high-speed rotation, the drive cavity 203 and the mounting cavity 202 are connected by a through groove. The size of the through groove is adapted to the tooth surface of the drive gear 601. One side of the tooth surface of the drive gear 601 passes through the through groove and meshes with the inner tooth 302 set in the anti-condensation component 3 to realize power transmission. When the drive gear 601 rotates, it can drive the annular plate 301 to rotate synchronously. Inside the drive cavity 203, a horizontal worm 604 is provided on one side of the worm wheel 603. The worm 604 is made of stainless steel. The worm 604 and the worm wheel 603 mesh with each other to form a worm gear transmission mechanism with self-locking function. The function is to prevent the anti-condensation component 3 from rotating on its own when there is no power drive, ensuring structural stability. Inside the drive cavity 203, a fixing plate 6041 is fixed to one end of the worm 604. One end of the worm 604 is rotatably mounted on the fixing plate 6041. The fixing plate 6041 is made of insulating steel plate and is used to support one end of the worm 604. The other end of the worm 604 is fixed with a connecting shaft 605. The connecting shaft 605 is made of stainless steel and its diameter is smaller than that of the worm 604. The connecting shaft 605 extends through the mounting plate 2 into the protective shell 103 and is fixed with a shaft block 606. A sealing ring is provided at the penetration part between the connecting shaft 605 and the mounting plate 2 to ensure sealing. The ring is made of aging-resistant silicone rubber to prevent moisture leakage inside the drive cavity 203 and to prevent water vapor inside the protective shell 103 from entering the drive cavity 203. The diameter of the shaft block 606 is larger than the diameter of the connecting shaft 605. A transmission wheel 607 is fixedly installed on the outer wall of the shaft block 606. The transmission wheel 607 adopts a sprocket structure. The corresponding transmission wheels 607 in the three transmission components 6 are connected by a transmission chain 6071. The transmission chain 6071 is made of stainless steel chain to ensure that the three transmission components 6 can operate synchronously, thereby driving the anti-condensation components 3 corresponding to the three pole posts 102 to rotate synchronously and reciprocate, realizing synchronous anti-condensation treatment of the three pole posts 102 and improving anti-condensation efficiency. A protective shell 103 is bolted to one side of the outer wall of the housing 101. The protective shell 103 is made of waterproof and dustproof material to protect the drive wheel 607, drive chain 6071, and reciprocating motor 4 located inside, preventing outdoor rain, dust, and moisture from corroding these components and affecting their operational stability. A sealing gasket made of aging-resistant silicone rubber is installed at the contact point between the protective shell 103 and the housing 101 to enhance the seal between them and prevent external moisture intrusion. A waterproof vent valve is installed on the side wall of the protective shell 103. This valve balances the air pressure inside the protective shell 103 with the outside air, preventing pressure differences caused by temperature changes from damaging the sealing gasket. It also prevents rain and moisture from entering the protective shell 103 through the vent. One end of the mounting plate 2 extends through the housing 101 into the protective shell 103. A sealing ring is installed at the contact point between the mounting plate 2 and the housing 101. The mounting plate 2 is made of aging-resistant silicone rubber and fits tightly against the contact surface of the housing 101 to prevent moisture inside the housing 101 from leaking through the penetration. It also prevents water vapor inside the protective shell 103 from entering the housing 101, further ensuring the sealing performance of the device. A reciprocating motor 4 is installed on the inner wall of the protective shell 103 by screws. The reciprocating motor 4 is a low electromagnetic interference type motor. The output end of the reciprocating motor 4 is connected to the end flange of one of the shaft blocks 606. The reciprocating motor 4 is electrically connected to the primary and secondary fusion control terminal of the circuit breaker body 1. The control terminal has a built-in temperature and humidity sensor. The acquisition probe of the temperature and humidity sensor is placed in the low-voltage non-electric field area of ​​the inner wall of the pole 102 and is insulated. The lead wire is wired through a sealed perforation without affecting the insulation. It is used to collect humidity data inside the pole 102 in real time and transmit the collected humidity data to the control terminal. The control terminal can control the start, stop and speed of the reciprocating motor 4 according to the humidity data inside the pole 102 to realize intelligent control of anti-condensation without manual intervention.

[0023] First, the entire circuit breaker body 1 is fixed on the column mounting bracket through the ear plates 104 and screw holes on both sides of the housing 101 to complete the installation and fixing of the device. Then, the reciprocating motor 4 is connected to the primary and secondary fusion control terminal of the circuit breaker body 1 to put the device into standby mode. When condensation occurs inside the pole post 102 due to changes in ambient temperature, the temperature and humidity sensor built into the control terminal collects humidity data inside the pole post 102 in real time. When the collected humidity data is higher than a preset threshold, the control terminal automatically starts the reciprocating motor 4. The output end of the reciprocating motor 4 drives the shaft block 606 connected to its flange to rotate. The shaft block 606 drives the connecting shaft 605 and the worm gear 604 to rotate synchronously. The worm gear 604 drives the worm wheel 603 to rotate. The worm wheel 603 drives the shaft 602 and the drive gear 601 on the shaft 602 to rotate synchronously. The drive gear 601 drives the meshing inner gear 302 to rotate, so that the annular plate 301 reciprocates within the mounting cavity 202. When the annular plate 301 rotates, the slide rail 305 above it slides in the groove on the top wall of the mounting cavity 202, which guides and limits the annular plate 301, ensuring that the annular plate 301 rotates smoothly. When the annular plate 301 reciprocates, it drives the scraper 304 to reciprocate synchronously. During the movement, the scraper 304 can first scrape off the condensation generated on the inner wall of the pole post 102, and then absorb the water left after scraping through the sponge strip. Since the transmission wheel 607 in the three transmission components 6 is driven by the transmission chain 6071, when one of the shaft blocks 606 rotates, it can drive the other two shaft blocks 606 to rotate synchronously through the transmission wheel 607 and the transmission chain 6071, thereby driving the anti-condensation components 3 corresponding to the three pole posts 102 to reciprocate synchronously, realizing synchronous anti-condensation treatment of the three pole posts 102 and improving the anti-condensation efficiency. When the temperature and humidity sensor detects that the humidity inside the pole 102 is lower than the preset threshold, the control terminal automatically controls the reciprocating motor 4 to stop, and the anti-condensation component 3 to stop rotating, avoiding ineffective operation and saving energy. This prevents condensation from adhering to the inner wall of the pole 102 and the surface of the secondary wiring terminals, effectively improving the anti-condensation efficiency, significantly reducing the risk of decreased insulation performance, surface flashover, and short circuit faults caused by condensation, and improving operational reliability. It also simultaneously cleans the dust adhering to the inner wall of the pole 102, preventing dust accumulation from further affecting the insulation performance.

[0024] Please see Figure 4 and Figure 6As shown, the annular plate 301 has multiple liquid permeation holes 303, and the inner wall of the mounting cavity 202 has an annular guide groove 2022. All the liquid permeation holes 303 are located above the guide groove 2022. The liquid permeation holes 303 are used to guide the condensate absorbed by the sponge strip and the condensate scraped off by the scraper 304 into the guide groove 2022 below. The guide groove 2022 has a V-shaped cross-section to facilitate the convergence and flow of condensate. A liquid guide pipe 5 is connected to the lower surface of the mounting plate 2 at the guide groove 2022. A miniature one-way valve is added inside the liquid guide pipe 5 to prevent water vapor backflow. The liquid guide pipe 5 is connected to the housing 1. The penetration parts of the wall are sealed with sealant to prevent external moisture from entering. The bottom end of the liquid guide tube 5 penetrates the wall of the box 101 and connects to the collection box 501. The collection box 501 is installed on the wall of the box 101 with screws and is located below the protective shell 103. The inside of the collection box 501 is filled with absorbent cotton 502. The absorbent cotton 502 is made of highly absorbent resin material, which can quickly absorb and store the condensation introduced by the liquid guide tube 5 to prevent condensation from overflowing. At the same time, the side wall of the collection box 501 is provided with a removable cover plate, which makes it easy to open the cover plate to replace the absorbent cotton 502 later, reducing operation and maintenance costs.

[0025] When the scraper 304 scrapes the condensate off the inner wall of the pole post 102, the scraped condensate will flow downward along the scraper 304 and collect in the annular plate 301. It will then fall into the guide groove 2022 in the lower installation cavity 202 through the liquid permeation hole 303. After the guide groove 2022 collects the condensate, it will be guided into the collection box 501 through the liquid guide pipe 5. The absorbent cotton 502 in the collection box 501 will quickly absorb and store the condensate, preventing the condensate from accumulating inside the installation cavity 202. When the absorbent cotton 502 in the collection box 501 is saturated, the maintenance personnel can open the cover plate on the side wall to replace the absorbent cotton 502, which is convenient to operate.

[0026] The working principle of this invention is as follows: When condensation occurs inside the pole post 102 due to changes in ambient temperature, the temperature and humidity sensor built into the control terminal collects humidity data inside the pole post 102 in real time. When the collected humidity data is higher than a preset threshold, the control terminal automatically starts the reciprocating motor 4. The output end of the reciprocating motor 4 drives the shaft block 606 connected to its flange to rotate. The shaft block 606 drives the connecting shaft 605 and the worm gear 604 to rotate synchronously. The worm gear 604 drives the worm wheel 603 to rotate. The worm wheel 603 drives the shaft 602 and the drive gear 601 on the shaft 602 to rotate synchronously. The drive gear 601 drives the meshing inner gear 302 to rotate, so that the annular plate 301 reciprocates within the mounting cavity 202. When the annular plate 301 rotates, the slide rail 305 above it slides in the groove on the top wall of the mounting cavity 202, which guides and limits the annular plate 301, ensuring that the annular plate 301 rotates smoothly. When the annular plate 301 reciprocates, it drives the scraper 304 to reciprocate synchronously. During the movement, the scraper 304 first scrapes off the condensation generated on the inner wall of the electrode post 102, and then absorbs the remaining moisture through the sponge strip. The scraped condensation flows downward along the scraper 304, collects in the annular plate 301, and falls into the guide groove 2022 in the lower mounting cavity 202 through the liquid permeation hole 303. After the guide groove 2022 collects the condensation, it is guided into the collection box 501 through the liquid guide pipe 5. The absorbent cotton 502 inside the tube quickly absorbs and stores condensation. When the shaft block 606 rotates, it can drive the other two shaft blocks 606 to rotate synchronously through the transmission wheel 607 and the transmission chain 6071. This, in turn, drives the anti-condensation components 3 corresponding to the three pole posts 102 to rotate synchronously, thus achieving synchronous anti-condensation treatment of the three pole posts 102. When the temperature and humidity sensor collects the humidity data inside the pole post 102 and it is lower than the preset threshold, the control terminal automatically controls the reciprocating motor 4 to stop, and the anti-condensation components 3 stop rotating, avoiding ineffective operation and saving energy.
