Description

Technical Field

[0001] This invention relates to the field of power technology, specifically to an outdoor high-voltage AC circuit breaker. Background Technology

[0002] As a core switching device in outdoor power distribution systems, outdoor high-voltage AC circuit breakers integrate multiple functional components. The main components consist of poles, current transformers, zero-sequence current transformers, zero-sequence voltage sensors, spring operating mechanisms, protective enclosures, and automated feeder control units (FTUs). These components work together to achieve on / off control of high-voltage circuits, monitoring of electrical parameters, and automated regulation, meeting the operation and management requirements of outdoor high-voltage power distribution. The circuit breaker's external protection is constructed with a high-quality stainless steel enclosure. Stainless steel possesses excellent corrosion resistance and weather resistance, effectively isolating the harsh outdoor environment from the internal core components, delaying component aging, and improving the overall outdoor durability and operational stability of the circuit breaker.

[0003] In terms of the enclosure's structural layout, three poles are installed at equal intervals on its surface. To ensure the insulation and operational performance of the equipment, a certain distance is reserved between adjacent poles. However, this gap happens to create a suitable environment for birds to nest. Outdoor birds such as magpies easily gather twigs to build nests here. The flammable debris such as dry branches and weeds in the nests are easily affected by the high-voltage electric field, causing faults such as discharge and short circuits. At the same time, the birds' resting and nesting process may also damage the insulation gap between the poles, causing phase-to-phase discharge. This not only affects the normal switching and monitoring functions of the circuit breaker, but also creates serious power supply safety hazards, easily leading to accidents such as line tripping and power outages, threatening the stable operation of the outdoor power distribution network, and may also harm the birds themselves, bringing many troubles to outdoor power operation and maintenance. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an outdoor high-voltage AC circuit breaker to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an outdoor high-voltage AC circuit breaker, comprising: The housing has three poles evenly installed on its upper surface. Each of the three poles is connected to a current transformer at the middle of its outer surface. The lower end of each current transformer is connected to the housing. A support plate is set on the side of the current transformer away from the housing. The two ends of the support plate are connected to the housing through connectors. A column is rotatably connected to the middle of the upper surface of the support plate. Three hemispherical wind shields are installed in a ring at equal intervals on the upper end of the column. A cam is installed on the column. The push plate is provided in two sets, and both sets of push plates are slidably mounted on the upper surface of the housing. The two sets of push plates are alternately arranged with three pole posts. A connecting plate has cylinders installed at both ends, and a cylinder is fitted on each of the two cylinders. The cylinders are connected to a support plate. A connecting rod is installed at the end of the cylinder near the housing. The end of the connecting rod away from the cylinder passes through the cylinder and is connected to a push plate. A compression spring is fitted on the connecting rod and is located inside the cylinder. The connecting plate and a cam cooperate to drive the push plate to move.

[0006] While retaining the core functions of the original enclosure, poles, and current transformers, it integrates bird-proof components such as trays, windshields, push plates, and connecting plates to solve the power supply safety hazards caused by birds nesting between poles. The push plate is arranged alternately with the poles, and the mechanical linkage of the cam and connecting plate enables the push plate to slide back and forth to drive away birds. It is environmentally friendly and suitable for outdoor environments, with no chemical agents or additional energy consumption. The configuration of compression springs gives the push plate the ability to automatically reset, ensuring the continuity of mechanical action. The overall structure is seamlessly integrated with the circuit breaker, without interfering with the original electrical performance, and takes into account both bird-proof function and equipment operation stability.

[0007] Specifically, a U-shaped frame is installed at the center of the side of the connecting plate facing away from the housing. A roller is rotatably installed inside the U-shaped frame, and the roller makes rolling contact with the cam. The combination of the U-shaped frame and the roller transforms the sliding friction between the cam and the connecting plate into rolling friction, significantly reducing the frictional resistance of the mechanical transmission, avoiding component wear and jamming, ensuring that the cam rotation can accurately and efficiently drive the connecting plate to move, and making the reciprocating sliding of the push plate smoother. The rolling contact between the roller and the cam is evenly stressed, reducing the wear rate of both, extending the service life of the mechanical structure, ensuring the long-term stable operation of the bird deterrent action, and adapting to the high-frequency action requirements in complex outdoor environments.

[0008] Specifically, support plates are installed at both ends of the tray. A lug is installed at the end of each support plate away from the tray, and the lug is connected to the housing via connecting screws. A support ear is installed at the end of the cylinder away from the housing, and the lower end of the support ear is connected to the support plate. The support plates and lugs provide robust mounting support for the tray, forming a stable connection structure between the tray and the housing. This structure can withstand the influence of strong outdoor winds, vibrations, and other external forces, preventing the bird-proof components from shifting or loosening. The detachable connection method of the connecting screws allows for modular assembly and disassembly of the tray, eliminating the need to disassemble the core components of the circuit breaker, facilitating on-site installation, debugging, and subsequent maintenance of the bird-proof structure. The support ear securely connects the cylinder to the support plate, providing a stable mounting foundation for the transmission structure of the cylinder, column, and connecting rod, preventing component wobbling during transmission.

[0009] Specifically, two positioning sleeves are installed on the side of the housing facing the pallet. The upper end of each positioning sleeve is open, and a connector block is inserted inside. One side of the connector block has a screw hole that mates with a connecting screw, and the side of the positioning sleeve facing away from the housing has a small hole that mates with the screw hole. One end of the connecting screw passes through the lug portion and the small hole, and is threaded into the screw hole. The cooperation between the positioning sleeve and the connector block provides precise positioning for the pallet installation, allowing the connecting screw in the lug portion to quickly align with the screw hole, improving on-site installation efficiency. The screw hole of the connector block mates with the connecting screw, making the connection between the pallet and the housing more secure and preventing loosening during long-term use. The structural design of the positioning sleeve does not damage the original structure of the housing, balancing installation stability and equipment integrity. Furthermore, the connector block can be flexibly replaced, reducing maintenance costs after component damage.

[0010] Specifically, an L-shaped bracket is provided between the positioning sleeve and the ear base. One end of the L-shaped bracket is connected and fixed to the positioning sleeve. A through hole is opened on the side of the L-shaped bracket facing the positioning sleeve. The through hole is aligned with the small hole, and the connecting screw passes through the channel formed by the small hole and the through hole. With the support of the L-shaped bracket, part of the connecting screw is exposed, which facilitates the separation of the support plate and the housing by cutting off the screw later.

[0011] Specifically, a guide hole is provided at the center of the side of the cylinder facing the push plate. The connecting rod passes through the guide hole, and the diameter of the connecting rod is equal to the inner diameter of the guide hole. The diameter of the cylinder is equal to the inner diameter of the cylinder. The fit between the guide hole and the connecting rod, and the matching of the inner diameters of the cylinder and the cylinder, provide strict axial guidance for the movement of the connecting rod and the cylinder, preventing them from deviating, skewing, or jamming during transmission. This ensures that the push plate always slides back and forth in a straight line, making the bird-repelling action smooth. The fact that the diameter of the connecting rod is equal to the inner diameter of the guide hole reduces the backlash and wobble during the movement of the connecting rod, reduces component wear, and improves the efficiency of mechanical transmission. This allows the power of the cam to be transmitted to the push plate without loss, ensuring the bird-repelling effect.

[0012] Specifically, a vertical hole is formed on one side of the upper surface of the cam, and the rod passes through the vertical hole. The surface of the rod is machined with external threads, and nuts are provided on both the upper and lower sides of the vertical hole. The nuts are threadedly connected to the rod. The cam is sleeved on the rod through the vertical hole. With the cooperation of the nuts on the upper and lower sides, the installation height of the cam on the rod can be flexibly adjusted, thereby changing the contact area between the cam and the roller, which facilitates the even wear of the roller.

[0013] Specifically, a flange for connecting the motor output shaft is installed at the lower end of the column, and two positioning seats for limiting the motor position are installed on the lower surface of the support plate. The two positioning seats are symmetrically arranged about the column, and the positioning seats have an L-shaped structure. The horizontal part of the positioning seats has mounting holes for inserting bolts. The flange at the lower end of the column can be directly connected to the motor output shaft, enabling the motor to drive the column to rotate. The two symmetrically arranged positioning seats can limit the installation position of the motor, ensuring that the motor output shaft rotates coaxially with the column, avoiding eccentricity and wobbling when the column rotates, and ensuring the stable operation of the cam and the windshield. The mounting hole design of the positioning seats allows the motor to be detachably fixed, facilitating the inspection, replacement, and subsequent maintenance of the motor.

[0014] Specifically, three radial rods are installed in a ring at equal intervals on the upper end of the column, and the ends of the radial rods furthest from the column are connected to the windshield. The three radial rods are arranged in a ring at equal intervals, which makes the force on the windshield more even and the rotation more stable.

[0015] Specifically, the upper surface of the push plate is recessed downwards to form multiple equidistant blind holes, which are arranged along the length of the push plate. Thin rods are installed within each blind hole, and these rods are arranged vertically. The thin rods are mounted on the push plate through the blind holes, resulting in a uniform and secure installation that prevents them from easily falling off. Furthermore, the vertical structure of the thin rods does not affect the sliding motion of the push plate, nor does it interfere with the original components and operating space of the circuit breaker. The vertical thin rods on the push plate further increase the difficulty for birds to land on the surface of the enclosure and in the gap between the poles. Combined with the reciprocating sliding of the push plate, this creates a dual bird-repelling effect of physical barrier and dynamic deterrence, making bird control more thorough.

[0016] The beneficial effects of this invention are: Two sets of push plates are arranged alternately with the poles. Through the linkage of the cam and the connecting plate, the push plates are driven to slide back and forth on the surface of the box. This can directly drive away birds that are staying in the gaps between the poles and on the surface of the box, while also disrupting the birds' nesting behavior and preventing them from building nests between the poles. The vertical thin rods on the push plates further increase the difficulty for birds to stay, and together with the movement of the push plates, they form a double physical repulsion effect, making the bird repulsion more thorough.

[0017] Three hemispherical wind deflectors are arranged equidistantly in a ring at the upper end of the column. Under the action of wind, the wind deflectors drive the column to rotate. The rotation of the column drives the cam to rotate. The cam and the connecting plate work together to push the cylinder and the connecting rod to slide along the cylinder. At this time, the compression spring is in a reciprocating compression and expansion state, thereby driving the push plate to move back and forth. The entire transmission structure is a pure mechanical linkage, which can realize the smooth and continuous movement of the push plate, and the bird deterrence effect is stable, which is suitable for long-term use in complex outdoor environments.

[0018] The tray is connected to the housing via a support plate and ear mounts. The overall structure is modular and can be disassembled and installed individually without disassembling the core components of the circuit breaker. This facilitates the installation, commissioning, and subsequent maintenance of the bird deterrent structure. The positioning sleeve and plug-in block provide installation positioning for the tray, allowing the connecting screws of the ear mounts to quickly align with the screw holes, thus improving on-site installation efficiency.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-8 This invention provides a technical solution: an outdoor high-voltage AC circuit breaker, comprising a housing 100, three poles 101 evenly mounted on the upper surface of the housing 100, and current transformers 102 connected to the middle of the outer surface of each of the three poles 101, with the lower end of the current transformers 102 connected to the housing 100; a support plate 500 is disposed on the side of the current transformers 102 away from the housing 100, and support plates 501 are mounted on both ends of the support plate 500, with a lug 5011 mounted on the end of the support plate 501 away from the support plate 500. The ear-shaped base 5011 is connected to the housing 100 via connecting screws 203. Two positioning sleeves 200 are installed on the side of the housing 100 facing the tray 500. The upper end of each positioning sleeve 200 is open, and a connector block 201 is inserted inside. One side of the connector block 201 has a screw hole that mates with the connecting screw 203, and the side of the positioning sleeve 200 away from the housing 100 has a small hole that mates with the screw hole. One end of the connecting screw 203 passes through the ear-shaped base 5011 and the small hole, and is threaded into the screw hole. The positioning sleeves 200 and connector blocks 201 cooperate to provide positioning and guidance for the installation of the tray 500, allowing the connecting screw 203 of the ear-shaped base 5011 to quickly align with the screw hole of the connector block 201. This eliminates the need for repeated adjustments to the installation position of the tray 500, improving the on-site assembly efficiency of the bird-proof structure.

[0022] The screw holes of the plug block 201 and the connecting screws 203 precisely engage, ensuring a tighter and more secure connection between the tray 500 and the enclosure 100. This effectively resists the effects of outdoor vibrations, strong winds, and other external forces, preventing loosening or displacement during long-term use. The positioning sleeve 200 adopts an externally mounted structure design, directly assembled onto the surface of the enclosure 100. No drilling or welding is required on the enclosure 100, preserving its original structure and integrity and ensuring the overall performance of the circuit breaker remains unaffected. Furthermore, the plug block 201 is an independently assembled structure; if wear or damage occurs, it can be disassembled and replaced separately without requiring the replacement of the entire positioning sleeve 200 or tray 500, reducing subsequent maintenance costs and operational difficulties.

[0023] An L-shaped bracket 202 is provided between the positioning sleeve 200 and the ear base 5011. One end of the L-shaped bracket 202 is connected and fixed to the positioning sleeve 200. The side of the L-shaped bracket 202 facing the positioning sleeve 200 has a through hole, which is aligned with a small hole. The connecting screw 203 passes through the channel formed by the small hole and the through hole. Relying on the support and limitation of the L-shaped bracket 202, part of the rod of the connecting screw 203 can remain exposed, without the need to disassemble other parts. If it is necessary to separate the support plate 501 from the housing 100 later, the disassembly can be completed by cutting off the connecting screw 203. The operation is convenient and efficient, reducing the difficulty of on-site disassembly.

[0024] A column rod 502 is rotatably connected to the middle of the upper surface of the pallet 500. Three hemispherical windshields 504 are installed in a ring at equal intervals on the upper end of the column rod 502. Three radial rods 5041 are installed in a ring at equal intervals on the upper end of the column rod 502. The end of the radial rod 5041 away from the column rod 502 is connected to the windshield 504. The radial rod 5041 serves to connect the column rod 502 and the windshield 504.

[0025] Two sets of push plates 300 are provided, both of which are slidably mounted on the upper surface of the housing 100. The two sets of push plates 300 are alternately arranged with the three pole posts 101. The upper surface of the push plate 300 is recessed downwards to form multiple equidistant blind holes, which are arranged along the length of the push plate 300. Thin rods 301 are installed within these blind holes, arranged vertically. The thin rods 301 are assembled using the blind holes on the push plate 300, maintaining a uniform and equidistant layout while ensuring a secure connection to the push plate 300, preventing them from easily loosening or falling off during outdoor use. The vertical arrangement of the thin rods 301 does not interfere with the reciprocating sliding motion of the push plate 300, nor does it occupy the operating space of the original components of the circuit breaker, thus not affecting the normal operation of the equipment. These vertical thin rods 301 can form a physical barrier between the surface of the box 100 and the gap between the pole 101, increasing the difficulty for birds to stay in this area. Combined with the dynamic sliding of the push plate 300, a bird-repelling effect is formed, achieving a dual bird-prevention function of physical barrier and dynamic repelling. This eliminates the possibility of birds staying and nesting from the root, making the bird-prevention and bird-repelling effect more thorough.

[0026] Both ends of the connecting plate 400 are equipped with cylinders 401, and each cylinder 401 is fitted with a cylindrical tube 402. The end of the cylindrical tube 402 away from the housing 100 is equipped with a lug 4021, and the lower end of the lug 4021 is connected to the support plate 501. A connecting rod 403 is installed at the end of the cylinder 401 near the housing 100. The end of the connecting rod 403 away from the cylinder 401 passes through the cylindrical tube 402 and is connected to the push plate 300. A guide hole 4022 is opened in the middle of the side of the cylindrical tube 402 facing the push plate 300. The connecting rod 403 passes through the guide hole 4022. The diameter of the connecting rod 403 is equal to the inner diameter of the guide hole 4022, and the diameter of the cylinder 401 is equal to the inner diameter of the cylindrical tube 402. The matching of the guide hole 4022 with the connecting rod 403 and the inner diameter matching of the cylinder 401 and the cylindrical tube 402 provides strict axial guidance for the movement of the connecting rod 403 and the cylinder 401, preventing them from deviating, skewing or jamming during transmission, ensuring that the push plate 300 always slides back and forth in a straight line, making the bird-repelling action smooth.

[0027] A compression spring 405 is fitted onto the connecting rod 403 and is located inside the cylinder 402. The connecting plate 400 and the cam 503 cooperate to drive the push plate 300 to move. A U-shaped frame 404 is installed in the middle of the side of the connecting plate 400 facing away from the box 100. A roller 4041 is rotatably installed inside the U-shaped frame 404. The cam 503 is installed on the column 502, and the roller 4041 rolls in contact with the cam 503. The two sets of push plates 300 and the pole post 101 are arranged alternately. With the mechanical linkage between the cam 503 and the connecting plate 400, the push plates 300 can be driven to slide back and forth on the surface of the box 100. This can directly drive away birds that are staying in the gaps between the pole posts 101 and on the surface of the box 101, and at the same time effectively interfere with and destroy the birds' nesting behavior, thus preventing them from nesting and roosting between the pole posts 101.

[0028] Three hemispherical windshields 504 are arranged in a ring at equal intervals at the upper end of the column 502. The windshields 504 can drive the column 502 to rotate autonomously with the help of outdoor wind. The rotation of the column 502 drives the cam 503 to rotate synchronously. The cam 503 and the connecting plate 400 cooperate to push the cylinder 401 and the connecting rod 403 to slide along the cylinder 402. At this time, the compression spring 405 in the cylinder 402 performs reciprocating compression and reset movements with the movement of the mechanism, thereby driving the push plate 300 to move continuously back and forth. The entire transmission system is a pure mechanical linkage structure, which does not require additional electric drive. It can realize the smooth and continuous movement of the push plate 300, and the bird-repelling effect is stable and reliable. It can adapt to the long-term use needs of complex outdoor environments such as windy conditions and large temperature differences.

[0029] A vertical hole is provided on one side of the upper surface of the cam 503, through which the rod 502 passes. The surface of the rod 502 is machined with external threads. Nuts 5031 are provided on both the upper and lower sides of the vertical hole, and the nuts 5031 are threadedly connected to the rod 502. The cam 503 is sleeved on the rod 502 through the vertical hole. The nuts 5031 provided on the upper and lower sides of the rod 502 can flexibly adjust the installation height of the cam 503. By adjusting, the contact position between the cam 503 and the roller 4041 can be changed, allowing different parts of the roller 4041 to participate in the transmission contact, thereby making the wear of the roller 4041 evenly distributed, avoiding excessive wear in some areas, and extending the service life of the roller 4041.

[0030] A flange 5021 for connecting the motor output shaft is installed at the lower end of the column 502. Two positioning seats 505 for limiting the position of the motor are installed on the lower surface of the support plate 500. The two positioning seats 505 are symmetrically arranged about the column 502. The positioning seats 505 have an L-shaped structure, and the horizontal part of the positioning seats 505 has mounting holes for inserting bolts. The flange 5021 at the lower end of the column 502 can be directly connected to the motor output shaft to realize the motor driving the column 502 to rotate. The two symmetrically arranged positioning seats 505 can limit the installation position of the motor, ensuring that the motor output shaft and the column 502 rotate coaxially, avoiding eccentricity or wobbling of the column 502 during rotation, and thus ensuring that the cam 503 and the windshield 504 always move smoothly and reliably. At the same time, the mounting holes on the horizontal part of the positioning seats 505 allow for the detachable fixing of the motor with bolts, which facilitates subsequent maintenance operations such as inspection and replacement of the motor and greatly reduces the difficulty of on-site operations.
