Description

Technical Field

[0001] This invention relates to the field of circuit breaker pole technology, specifically to a composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure. Background Technology

[0002] Outdoor pole-mounted circuit breakers are critical switching equipment in power distribution networks, operating outdoors for extended periods and requiring simultaneous compliance with multiple requirements, including insulation, windproofing, rainproofing, and condensation prevention. Currently, most mainstream poles employ epoxy resin sealing or silicone rubber composite insulation structures. Through full sealing, water-repellent skirts, and internal moisture-proof design, they enhance outdoor environmental adaptability, resisting wind and rain, suppressing internal condensation, and ensuring insulation safety. However, these structures, in order to enhance protection, generally use thick-layer full-coverage sealing, significantly weakening the heat dissipation channels and resulting in poor overall heat dissipation.

[0003] When equipment operates under continuous current, the heat generated in the arc-extinguishing chamber and conductive circuit is difficult to dissipate quickly, easily leading to excessive internal temperature rise, accelerated insulation aging, reduced arc-extinguishing performance, and even affecting current-carrying capacity and service life. In areas with high humidity and large temperature differences, while sealed structures can reduce condensation, insufficient heat dissipation creates internal and external temperature differences, which in turn exacerbates the risk of localized condensation and reduces insulation reliability. Existing technologies struggle to balance protection and heat dissipation; stronger protection often results in poorer heat dissipation, hindering the stable operation of equipment under heavy loads and harsh environments. Therefore, developing a pole structure that combines composite insulation, wind, rain, and condensation protection with efficient heat dissipation is crucial for improving the reliability of power distribution network equipment. Summary of the Invention

A bottom seat is provided at the bottom of the pole shell, and a drying chamber is fixedly connected to the top of the bottom seat. The drying chamber is embedded in the bottom of the inner tube cover and is connected to the airflow channel through a lower connecting hole.

[0007] Preferably, the drying chamber is filled with a desiccant, and the top of the drying chamber has ventilation holes.

[0008] Preferably, a metal heat exchange plate is fixedly connected to the inner wall of the electrode shell, and multiple heat exchange fins are fixedly connected to the side of the metal heat exchange plate. The multiple heat exchange fins are distributed in a circumferential shape and divide the airflow channel into multiple vertical channels.

[0009] Preferably, both ends of the top of the pole housing are provided with placement cavities, and the two airbag balls are respectively placed inside the placement cavities at both ends. One end of the connecting air pipe is connected to the cavity inside the inner tube cover, and the other end of the connecting air pipe is connected to the top of the airflow channel. A spring support frame is provided inside the airbag ball.

[0011] Preferably, a guide plate is fixedly connected to the top of the air collecting hood, and a tail airbag is fixedly connected to the end of the guide plate away from the U-shaped groove.

[0012] Preferably, the fixed frame is provided with a stroke amplification structure and a pressing frame inside, and the pressing frame is movably installed on the outer surface of the airbag bulb.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure, which has the following beneficial effects: 1. This composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure utilizes an airflow channel built between the pole's outer shell and inner casing. By leveraging the thermodynamic principle of hot air rising naturally and cold air sinking naturally, a stable closed-loop circulating airflow is formed within the pole body. This circulation continuously dissipates heat and cools the insulating rod and vacuum interrupter chamber without external energy drive, effectively solving the problem of poor heat dissipation performance in existing pole structures. It significantly reduces internal temperature rise, delays insulation aging, and improves arc-extinguishing performance.

[0015] 2. This composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker features a pole structure with metal heat exchange plates and multiple circumferentially distributed heat exchange fins fixedly connected to the inner wall of the airflow channel. This divides the airflow channel into multiple vertically aligned channels, significantly increasing the heat exchange area. When hot air flows through this area, it can fully exchange heat with the cooler metal heat exchange plates and fins. The heat is then conducted outwards through the pole shell, significantly improving heat exchange efficiency and enabling the equipment to better adapt to heavy-load and high-current operating conditions. A desiccant-filled drying chamber is embedded at the bottom of the internal casing. Cold air must pass through the drying chamber before returning to the cavity through the lower connecting hole, ensuring thorough drying and effectively removing moisture from the circulating airflow. This prevents condensation at its source and significantly improves the operational reliability of the equipment in humid, rainy, and other harsh environments.

[0016] 3. The composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker features a wind-powered component that utilizes external natural wind energy. By capturing wind power through a wind collector, the moving block reciprocates, periodically compressing the airbag and continuously extracting hot air from the cavity and forcing it into the airflow channel. This significantly accelerates the airflow circulation rate, greatly improves heat dissipation efficiency, requires no additional electrical energy consumption, and is environmentally friendly with low operating costs.

[0017] 4. This composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure features a guide plate fixedly connected to the top of the wind collector shroud, with a tail airbag connected to the rear end of the guide plate. When wind blows towards the tail airbag, it generates a deflection force, causing the wind collector shroud to automatically rotate on top of the fixed frame. This ensures that the opening of the wind collector shroud always faces the wind direction. Regardless of changes in the external wind direction, the wind collector shroud can continuously and effectively receive wind power to drive the moving block to reciprocate, ensuring that the wind power component can operate normally under various wind conditions.

[0018] 5. The composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure features a stroke amplification structure (including a fixed rack, transmission gear, and transmission rack) inside the fixed frame. Stroke amplification is achieved through the meshing transmission principle of the gear and rack, allowing the movable rod to drive the pressing frame to produce a larger downward movement with a smaller downward stroke. This applies greater pressure to the airbag bulb, resulting in a larger amount of gas discharged in one compression cycle. This effectively increases the airflow velocity within the airflow channel, further improving heat dissipation efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Example 1: This embodiment provides a composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure, which has the following technical features.

[0033] Please see Figures 1 to 4 As shown, the present invention provides a composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure, including a pole body 1 and two wind power components 2, which are respectively rotatably installed at both ends of the top of the pole body 1. Please see Figures 2 to 3 As shown, in Embodiment 1, the specific structure of the pole body 1 includes a pole shell 11 and an inner tube cover 14. An airflow channel 15 is formed between the pole shell 11 and the inner tube cover 14. The top of the inner tube cover 14 is provided with multiple upper connecting holes 110, and the bottom of the inner tube cover 14 is provided with multiple lower connecting holes 17. A cavity is provided inside the inner tube cover 14, and it is connected to the upper and lower ends of the airflow channel 15 through the lower connecting holes 17 and the upper connecting holes 110, respectively, so that the airflow inside the pole shell 11 circulates and heat dissipation is achieved.

[0034] The inner tube cover 14 has an insulating pull rod 12 at the lower end of its internal cavity and a vacuum interrupter 13 at the upper end of its internal cavity. The insulating pull rod 12 is connected to the vacuum interrupter 13. A support frame is provided in the middle of the inner tube cover 14 to support the vacuum interrupter 13, while not affecting the airflow through the support frame.

[0035] The bottom of the pole housing 11 is provided with a bottom seat 16, and the top of the bottom seat 16 is fixedly connected to a drying chamber 18. The drying chamber 18 is embedded in the bottom of the inner tube cover 14 and is connected to the airflow channel 15 through the lower connecting hole 17. The interior of the drying chamber 18 is filled with desiccant, and the top of the drying chamber 18 is provided with a vent.

[0036] In this embodiment, as Figure 3 As shown, the inner cavity of the pole body 1 contains an insulating pull rod 12 and a vacuum interrupter 13. During long-term operation of the equipment, the insulating pull rod 12 and the vacuum interrupter 13 generate a large amount of heat, forming a hot zone inside the inner tube cover 14 cavity. The airflow channel 15 between the inner tube cover 14 and the pole shell 11 contains metal heat exchange plates 101, which exchange heat with the pole shell 11 using metal. The outer area of ​​this channel has a relatively low temperature, forming a cold zone. According to the principle of hot air rising, the hot air in the lower half of the cavity decreases in density after being heated and rises upward, entering the interior of the airflow channel 15 through multiple upper connecting holes 110 opened at the top of the inner tube cover 14.

[0037] like Figure 4As shown, a metal heat exchange plate 101 is fixedly connected to the inner wall of the pole shell 11 inside the airflow channel 15. Multiple heat exchange fins 102 are fixedly connected to the side of the metal heat exchange plate 101. The multiple heat exchange fins 102 are distributed in a circumferential shape and divide the airflow channel 15 into multiple vertical channels.

[0038] Hot air entering the airflow channel 15 flows through the area where the metal heat exchange plates 101 and heat exchange fins 102 are located. The metal heat exchange plates 101 are fixedly connected to the inner wall of the electrode housing 11, and the heat exchange fins 102 are distributed in a circumferential shape, dividing the airflow channel 15 into multiple vertical channels. This structure significantly increases the heat exchange area. When the hot air flows through the metal heat exchange plates 101 and heat exchange fins 102, it exchanges heat with the cooler metal heat exchange plates 101 and heat exchange fins 102, and the heat is conducted outward through the electrode housing 11. After releasing heat, the temperature of the hot air decreases and its density increases, causing it to sink within the airflow channel 15. The sinking cold air enters the area where the drying chamber 18 is located through the lower connecting hole 17 opened at the bottom of the internal tube cover 14. The drying chamber 18 is filled with desiccant, and the cold air flowing through the drying chamber 18 is fully dried, removing moisture and effectively preventing condensation.

[0039] After drying, the cold air enters the cavity of the inner tube cover 14 through the lower connecting hole 17, cooling the insulating rod 12 and the vacuum interrupter 13 inside the cavity. After absorbing heat from the heating element, the cold air's temperature rises again, becoming hot air, and then rises again, entering the airflow channel 15 through the upper connecting hole 110 for the next round of heat exchange. This cycle repeats, forming a stable closed-loop circulating airflow inside the electrode body 1, continuously dissipating heat and cooling the insulating rod 12 and the vacuum interrupter 13. This circulation process fully utilizes the thermodynamic principle of hot air naturally rising and cold air naturally sinking, achieving efficient heat dissipation without external energy drive, effectively solving the problem of poor heat dissipation performance in existing electrode structures.

[0040] In actual use, since the airflow relies on heat to drive the airflow circulation, the airflow rate is relatively slow, resulting in insufficient heat dissipation. In this invention, a wind power component 2 is also provided to increase the airflow and improve the airflow rate.

[0041] Example 2: This embodiment provides a composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] Please see Figures 1 to 7As shown, in Embodiment 2, the wind power assembly 2 includes a fixed frame 21, an airbag ball 22, and an air collecting hood 25. The air collecting hood 25 has a movable block 251 inside. The fixed frame 21 has a pressing rod 254 movably sleeved inside. Both ends of the airbag ball 22 are fixedly connected to one-way valves 23. One end of each one-way valve 23 is fixedly connected to a connecting air pipe 24 to increase the airflow and improve the airflow rate.

[0043] The pole housing 11 has placement cavities at both ends of its top. Two airbags 22 are placed inside the placement cavities at both ends, with one end connected to the air tube 24 and connected to the cavity inside the inner tube cover 14, and the other end connected to the air tube 24 and connected to the top of the airflow channel 15.

[0044] In this embodiment, the airbag ball 22 is provided with a spring support frame 210 inside. The spring support frame 210 includes a folding frame that supports the upper and lower inner walls of the airbag ball 22. The folding frame is provided with a spring inside. When the airbag ball 22 is pressed, the spring support frame 210 is compressed. At this time, the one-way valve 23 connected to one end of the airflow channel 15 opens and the one-way valve 23 at the other end closes, thereby accelerating the airflow speed of the airflow channel 15.

[0045] like Figures 5-7 As shown, the fixing frame 21 is fixedly installed on the top of the pole housing 11. A rotating column is installed at the bottom of the air collecting hood 25 and is rotatably installed on the top of the fixing frame 21. An exhaust groove 253 is opened at one end inside the air collecting hood 25. A moving block 251 is slidably installed inside the air collecting hood 25. The bottom of the moving block 251 is provided with an inclined surface. A U-shaped groove 252 is opened at the top of the moving block 251 away from the exhaust groove 253. A pressing rod 254 is movably sleeved inside the fixing frame 21. The pressing rod 254 is movably installed at the bottom of the moving block 251 and is movably installed on the top of the airbag bulb 22.

[0046] In this embodiment, considering that the passive heat dissipation effect formed by natural convection alone is limited, the airflow speed is slow, the circulation flow is small, and the cooling effect is not obvious, a wind power component 2 is set to enhance heat dissipation.

[0047] like Figure 4 and Figure 5As shown, the working principle of the wind power assembly 2 is as follows: When wind blows towards the wind collector hood 25, the wind acts on the moving block 251 through the U-shaped groove 252, pushing the moving block 251 to slide inside the wind collector hood 25 towards the exhaust groove 253. During the movement, the inclined surface at the bottom of the moving block 251 gradually presses down on the top of the pressing rod 254 (a ball bearing can be installed on the top of the pressing rod 254 to reduce friction), causing the pressing rod 254 to slide downward inside the fixed frame 21. The bottom end of the pressing rod 254 then presses against the top of the airbag ball 22, compressing the airbag ball 22. A spring support frame 210 is provided inside the airbag ball 22, and the spring support frame 210 is compressed synchronously when the airbag ball 22 is compressed.

[0048] When the airbag bulb 22 is compressed, the gas pressure inside the airbag bulb 22 increases, and the one-way valve 23 at the end connected to the top of the airflow channel 15 is opened (this one-way valve 23 is an outlet valve that only allows gas to flow out from inside the airbag bulb 22 towards the connecting air pipe 24). The gas is squeezed into the top of the airflow channel 15 through the connecting air pipe 24, thereby increasing the airflow rate inside the airflow channel 15. After the pressing rod 254 continues to descend to the limit position, the moving block 251 continues to slide to the position of the exhaust slot 253. At this time, the air is discharged outward through the exhaust slot 253, and the wind force acting on the moving block 251 is released.

[0049] Under the elastic restoring force of the spring support frame 210, the airbag ball 22 resets and unfolds, creating a negative pressure inside. The one-way valve 23 at the end connected to the inner tube cover 14 cavity is opened (this one-way valve 23 is a one-way air inlet valve that only allows gas to flow into the airbag ball 22 from the connecting air pipe 24). Hot air from the inner tube cover 14 cavity is drawn into the airbag ball 22 through the connecting air pipe 24. As the pressing rod 254 rises under the reset action of the airbag ball 22, the inclined surface at the bottom of the moving block 251 is pushed back to its original position, and the U-shaped groove 252 faces the wind again, starting the next pressing cycle. This process repeats, with the wind power component 2 continuously drawing hot air out of the inner tube cover 14 cavity and pressing it into the airflow channel 15, significantly accelerating the airflow circulation rate and greatly improving heat dissipation efficiency. By setting one-way valves 23 at both ends of the airbag ball 22, one-way airflow is achieved, ensuring that the airflow circulates in a predetermined direction, further enhancing the heat dissipation effect.

[0050] Example 3: This embodiment provides a composite insulated, windproof, rainproof, and condensation-proof pole-mounted circuit breaker pole structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] Please see Figures 1 to 4 , Figure 8As shown, in Embodiment 3, the fixed frame 21 is internally equipped with a stroke amplification structure and a pressing frame 212. The pressing frame 212 is movably mounted on the outer surface of the airbag bulb 22. The stroke amplification structure includes a fixed box 211. A fixed rack 216 is fixedly connected to one end of the fixed box 211. A movable rod 214 is movably sleeved on the upper end of the fixed box 211. The movable rod 214 is movably mounted on the lower end of the movable block 251. A transmission gear 215 is rotatably mounted on the lower end of the movable rod 214. The outer surface of the transmission gear 215 meshes with the side of the fixed rack 216. A transmission rack 213 is provided on the side of the fixed box 211 away from the fixed rack 216. The bottom of the transmission rack 213 is connected to the pressing frame 212. A guide plate 26 is fixedly connected to the top of the air collector hood 25. A tail airbag 27 is fixedly connected to the end of the guide plate 26 away from the U-shaped groove 252.

[0052] In this embodiment, as Figure 8 As shown, in order to further increase the compression effect of the airbag bulb 22 and obtain a larger airflow, a stroke amplification structure and a pressing frame 212 are provided inside the fixing frame 21.

[0053] The specific working principle of the stroke amplification structure is as follows: When the air blows towards the U-shaped groove 252, the airflow pushes the moving block 251 to slide inside the air collection hood 25. The lower end of the moving block 251 pushes the movable rod 214 downward. A transmission gear 215 is rotatably mounted on the lower end of the movable rod 214. During the descent of the movable rod 214, the transmission gear 215 moves downward along the side of the fixed rack 216. Since the transmission gear 215 meshes with the fixed rack 216, the transmission gear 215 rotates while moving downward. The rotation of the transmission gear 215 drives the transmission rack 213 to move through the meshing action. The transmission rack 213 moves downward and drives the pressing frame 212 connected to its bottom to move downward. The pressing frame 212 is movably mounted on the outer surface of the airbag ball 22. When the pressing frame 212 moves downward, it applies a compressive force to the outer surface of the airbag ball 22, causing the airbag ball 22 to be compressed.

[0054] During this process, the transmission gear 215 rolls along the fixed rack 216 and drives the transmission rack 213. The meshing transmission principle of the gear and rack amplifies the stroke, allowing the movable rod 214 to drive the pressing frame 212 to move downwards with a smaller stroke. This results in the airbag bulb 22 being subjected to greater compressive force, producing a stronger compression effect. After the airbag bulb 22 is compressed, the gas inside is forced into the airflow channel 15 through the one-way valve 23 and the connecting air pipe 24. Due to the amplified compression stroke of the pressing frame 212, the compression amount of the airbag bulb 22 is greater, and more gas is discharged in one compression cycle, effectively increasing the airflow velocity within the airflow channel 15 and further improving heat dissipation efficiency. When the pressing rod 254 rises, the airbag bulb 22 resets and unfolds under the action of the spring support frame 210. The pressing frame 212 then rises and resets, and the hot air inside the inner tube cover 14 cavity is drawn into the airbag bulb 22, preparing for the next round of compression.

[0055] In addition, a guide plate 26 is fixedly connected to the top of the wind collector hood 25, and a tail airbag 27 is fixedly connected to the end of the guide plate 26 away from the U-shaped groove 252 (i.e., the tail end of the guide plate 26). The tail airbag 27 is located on the side facing the wind, and is positioned away from the U-shaped groove 252. The direction of the guide plate 26 is the same as the direction of the wind collector hood 25. When the tail airbag 27 is subjected to wind force, it will generate a deflection force, causing the wind collector hood 25 to rotate on the top of the fixing frame 21, so that the opening direction of the wind collector hood 25 always faces the wind direction. This design ensures that no matter how the external wind direction changes, the wind collector hood 25 can always face the wind direction, which facilitates the U-shaped groove 252 to continuously receive wind force to drive the moving block 251 to move back and forth.

[0056] The reciprocating motion of the moving block 251 is as follows: When the wind blows onto the U-shaped groove 252, it pushes the moving block 251 to move towards the exhaust groove 253 inside the air collecting hood 25. The moving block 251 pushes the pressing rod 254 down via the inclined surface at the bottom or drives the stroke amplification structure through the movable rod 214, thereby compressing the airbag ball 22. When the moving block 251 moves to the side of the exhaust groove 253, the U-shaped groove 252 deviates from the windward position, and the wind is discharged outward through the exhaust groove 253, and the wind force pushing the moving block 251 disappears. Under the reset of the airbag ball 22 (the elasticity of the spring support frame 210) and the rising action of the pressing rod 254 or the pressing frame 212, the moving block 251 is pushed back to the initial position, the U-shaped groove 252 faces the wind again, and the next round of reciprocating motion begins. Thus, under the continuous action of wind, the moving block 251 slides back and forth inside the wind collector hood 25, realizing the periodic compression and reset of the airbag ball 22, and continuously transporting the hot air in the cavity of the inner tube cover 14 to the airflow channel 15 for heat dissipation.

[0057] In summary, this invention, through the coordinated use of Embodiments 1 to 3, achieves highly efficient passive heat dissipation by utilizing the closed-loop circulating airflow formed within the pole body 1. Furthermore, the wind-powered component 2 further enhances the airflow circulation rate, enabling the pole structure to possess composite insulation, windproof, rainproof, condensation-proof, and highly efficient heat dissipation properties. This invention effectively solves the technical problems of existing pole structures where enhanced protection weakens the heat dissipation channel and results in poor heat dissipation performance. It can significantly reduce internal temperature rise, delay insulation aging, improve arc extinguishing performance, and extend equipment lifespan, which is of great significance for improving the operational reliability of power distribution network equipment under heavy loads and harsh environments.
