Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to an outdoor smart integrated pole-mounted circuit breaker. Background Technology

[0002] In the process of smart grid construction and distribution automation upgrades, outdoor pole-mounted circuit breakers, as key switching equipment, are widely used in the segmentation, interconnection, and protection of 10kV and below distribution lines. Their core function is to achieve rapid fault isolation and flexible switching of normal loads, directly affecting the reliability and stability of the distribution network. The ZW32 series vacuum circuit breaker, with its advantages of vacuum arc extinguishing, strong outdoor withstand capability, and high degree of integration, has become the mainstream choice for pole-mounted installations. This type of equipment needs to be exposed to complex outdoor environments for extended periods and undergoes long-distance land transportation to various installation sites in mountainous areas and suburbs. Therefore, structural protection during transportation has a significant impact on the equipment's factory quality and subsequent operational safety.

[0003] In existing technology, a typical structure of an outdoor pole-mounted circuit breaker includes a circuit breaker body and three poles fixed to its top surface. The top of each pole has a disconnecting switch terminal connected to an isolating switch, while the side walls are equipped with circuit breaker output terminals integrating current transformer functions. Support frames are fixed to opposite sides of the bottom surface of the circuit breaker body; these support frames are the core mounting carrier of the equipment. In actual engineering installation, a crossarm must be pre-erected horizontally between two utility poles, and then the circuit breaker support frame is secured to the top surface of the crossarm using bolts, completing the pole-mounting of the equipment. For long-distance transportation, the industry-standard protection method is to use foam bags to cover both the isolating switch terminal and the circuit breaker output terminals to reduce the risk of impact during transport.

[0004] During long-distance transportation of the aforementioned pole-mounted circuit breakers, although the foam wrapping protection effectively protects the horizontally arranged disconnector terminals on the top surface, preventing damage from bumps during transport, the vertically positioned outgoing terminals of the circuit breakers on the pole sidewalls are susceptible to displacement and shaking within the packaging box due to their cantilevered shape and the lack of rigid fixing structure in the foam bag. This shaking can easily cause the outgoing terminals of adjacent circuit breakers to collide with each other or directly impact the inner wall of the transport box, resulting in deformation of the conductive components, thread damage, or cracking of the insulating base. This severely affects the factory precision of the equipment and the reliability of subsequent electrical connections, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an outdoor intelligent integrated pole-mounted circuit breaker to solve the problem that during long-distance transportation, the protruding output terminal of the circuit breaker is easily bumped and knocked, resulting in deformation of conductive components, damage to threads, or cracking of the insulating base, which affects the accuracy of the equipment and the reliability of the connection.

[0006] The outdoor intelligent integrated pole-mounted circuit breaker provided in this application adopts the following technical solution: An outdoor intelligent integrated pole-mounted circuit breaker includes a main body and three poles fixed to the top surface of the main body. An upper connecting piece is fixed to the top surface of each pole, and a lower connecting piece is fixed to the outer periphery facing the front of the main body. Support plates are fixed to opposite sides of the bottom surface of the main body, and traction handles are rotatably connected to the left and right vertical sides. A mounting plate that can slide up and down is provided along the horizontal direction on the front vertical surface of the main body. A protective plate is rotatably connected to the lower edge of the mounting plate. The protective plate can be rotated to a vertically upward protective state and to a horizontal, retracted state below the main body. The exterior of the main body is provided with a locking component for limiting the protective plate in the retracted state and a positioning component for limiting the protective plate in the protective state.

[0007] By adopting the above technical solution, a sliding mounting plate is installed on the front of the main body, and a protective plate is rotatably connected to the lower edge of the mounting plate, allowing the protective plate to flexibly switch between vertical protection and horizontal storage states. During transportation, the protective plate rotates to the vertical state to provide rigid protection for the cantilevered protruding lower connecting piece, avoiding damage caused by bumps during transportation. During installation, the protective plate rotates to the horizontal storage state and fits against the bottom of the main body, significantly reducing the overall size of the equipment and facilitating hoisting operations and column installation. At the same time, locking and positioning components ensure stable positioning in both states, balancing transportation protection and installation convenience. This effectively solves the problems of insufficient rigidity and easy failure of existing foam protection, ensuring the factory precision of the equipment and the reliability of subsequent electrical connections.

[0008] Optionally, the locking component includes two locking rods that slide horizontally on the side of the pole when the protective plate is in the protective state and are coaxial, and an elastic pressing component disposed on the protective plate. Both of the support plates are provided with locking through holes. When the protective plate is in the retracted state, the elastic pressing component drives the two locking rods to slide in opposite directions, and the locking rods can be inserted into and pass through the locking through holes at this time.

[0009] By adopting the above technical solution, when the protective plate is switched to the horizontal storage state, the elastic compression component can automatically drive the two locking rods to slide back and forth, so that they can accurately insert into and pass through the locking through hole of the support plate, thereby achieving a stable limit on the storage state of the protective plate. This structure does not require additional manual locking, has a high degree of automation, and a reliable locking effect. It can effectively prevent the protective plate from rotating unexpectedly during installation, ensuring the safety of hoisting and installation operations. At the same time, it simplifies the operation process, reduces the labor intensity of workers, and further improves the efficiency of equipment installation.

[0010] Optionally, a guide ramp is provided at the outer edge of the ends of the two locking rods that are far apart from each other.

[0011] By adopting the above technical solution, a guide slope is provided on the outer edge of the ends of the two locking rods that are far apart from each other, which can play a guiding role when the protective plate is switched to the storage state and the locking rod is inserted into the locking through hole.

[0012] Optionally, the elastic compression member includes a first spring in a compressed state, a guide block fixed to the protective plate, and a protruding plate fixed to the outer periphery of the locking rod; the guide block has a guide hole for the locking rod to pass through, and anti-detachment protrusions are fixed on the outer periphery of the ends of the two locking rods that are close to each other. The protruding plate is located on the side of the guide block away from the anti-detachment protrusion, and the two ends of the first spring are fixedly connected to the sides of the guide block and the protruding plate that are close to each other.

[0013] By adopting the above technical solution, the elastic extrusion component consists of a first spring in a compressed state, a guide block, a protruding plate, and an anti-detachment protruding plate. The guide hole on the guide block provides a stable sliding trajectory for the locking rod, preventing the locking rod from deviating during sliding. The first spring in a compressed state continuously applies a pushing force to the protruding plate, ensuring that the locking rod can be stably inserted into the locking through hole when the protective plate is in the retracted state. Optionally, the positioning component includes an elastic positioning rod rotatably connected to the outer peripheral surface of the traction handle at one end. The elastic positioning rod has the property of elastic shortening. A positioning hook is fixed at the end of the elastic positioning rod away from the traction handle, and a locking hook hole is opened on the ends of the two locking rods that are far apart from each other. When the traction handle is in the protective state, it rotates to a vertically upward state, and the elastic positioning rod rotates to a horizontal state in the direction towards the protective plate. The positioning hook is then engaged in the locking hook hole. When the traction handle is in the protective state, it rotates to a vertically downward state, and the locking rod passes through the locking through hole. The elastic positioning rod rotates to a vertically downward state, and the positioning hook is then engaged in the locking through hole.

[0014] By adopting the above technical solution, the positioning component, through the cooperation of the elastic positioning rod and the positioning hook, combined with the rotation adjustment of the traction handle, achieves dual limiting of the protective plate in two states. When the protective plate is in the protective state, the traction handle is vertically upward, and the elastic positioning rod rotates horizontally to make the hook engage with the locking hole, firmly limiting the protective plate; when the protective plate is being stored, the traction handle is vertically downward, and the hook engages with the locking through hole, further locking the locking rod. The elastic shortening performance of the elastic positioning rod facilitates the engagement and disengagement of the hook, making operation convenient. The dual limiting design significantly improves the stability of the protective plate in both states, preventing accidental displacement of the protective plate during transportation or installation, and ensuring equipment safety.

[0015] Optionally, when the protective plate is in the protective state, a barrier plate located above the lower wiring piece is fixed on the top surface in the horizontal direction. When the protective plate is in the retracted state, the bottom edge of the barrier plate is flush with the bottom surface of the support plate.

[0016] By adopting the above technical solution, the barrier plate is fixed on the top surface of the protective plate in its protected state and is located above the lower terminal block. This provides supplementary protection to the lower terminal block during transportation, preventing damage from falling foreign objects or bumps and collisions, thus further improving the protection system. When the protective plate is switched to its retracted state, the bottom surface of the barrier plate is flush with the bottom surface of the support plate, forming a combined support structure with the protective plate and support plate. This increases the contact area between the equipment and the installation crossarm, improving the stability of the pole-mounted circuit breaker after installation and effectively preventing tilting or shaking due to uneven stress during equipment operation, ensuring long-term stable operation of the equipment.

[0017] Optionally, the barrier plate has a clearance through hole, and the main body has a connecting plate that passes through the clearance through hole and is parallel to the protective plate. When the protective plate is in the protective state, the connecting plate has an upper anti-detachment plate fixed on its top surface and a lower anti-detachment plate fixed on its bottom surface. When the protective plate is in the protective state, the bottom surface of the upper anti-detachment plate abuts against the top surface of the barrier plate, and the connecting plate protects the locking rod and the elastic pressing component at this time. When the protective plate is in the storage state, the upper anti-detachment plate can slide in a direction away from the barrier plate, and the top surface of the connecting plate at this time can be used to hold disassembly and assembly tools.

[0018] By adopting the above technical solution, the connecting plate penetrates the clearance hole of the barrier plate. When the protective plate is in the protective state, the upper anti-detachment plate abuts against the barrier plate. The connecting plate can protect the locking rod and the elastic pressing component, preventing dust and debris from adhering during transportation or in the outdoor environment, preventing parts from rusting or jamming, and ensuring the normal use of the locking structure. When the protective plate is stored and the equipment is under maintenance, the connecting plate can be slid out from under the protective plate. Its top surface can be used to hold disassembly and assembly tools, eliminating the need to carry an additional tool box, facilitating operation for staff, effectively improving maintenance efficiency, and combining protection and auxiliary maintenance functions, making it highly practical.

[0019] Optionally, a traction ring is fixed on the side of the upper anti-detachment plate away from the barrier plate.

[0020] By adopting the above technical solution, a traction ring is installed on the side of the upper anti-detachment plate away from the barrier plate, providing a convenient force application point for the sliding operation of the connecting plate. During maintenance, workers can easily pull the connecting plate through the traction ring to achieve quick sliding out and repositioning of the connecting plate. The operation is labor-saving and convenient, effectively reducing the difficulty of operation and improving the efficiency of maintenance work.

[0021] Optionally, an elastic snap-fit ​​element is provided on the inner wall of the clearance through hole, and a plurality of positioning grooves for the elastic snap-fit ​​element to be snapped into are evenly provided on the connecting plate.

[0022] By adopting the above technical solution, the elastic snap-fit ​​component on the inner wall of the clearance through hole cooperates with the positioning groove on the connecting plate. When the connecting plate slides along the clearance through hole, the elastic snap-fit ​​component can be snapped into the corresponding positioning groove, thereby achieving stable positioning of the connecting plate after sliding adjustment.

[0023] Optionally, the elastic snap-fit ​​component includes a compression spring and an arc-shaped protrusion. The inner wall of the clearance through hole is provided with a placement groove for the compression spring and the arc-shaped protrusion to be inserted. The compression spring squeezes one side of the arc-shaped protrusion, causing a part of the arc-shaped protrusion to protrude from the opening of the placement groove. The outer surface of the protruding part of the arc-shaped protrusion is an arc surface, and the arc length corresponding to this arc surface is a minor arc.

[0024] By adopting the above technical solution, the elastic locking component uses a compression spring in conjunction with an arc-shaped protrusion. The compression spring continuously applies pressure to the arc-shaped protrusion, causing the protrusion to protrude from the placement groove, facilitating engagement and positioning with the positioning groove. The protruding part of the arc-shaped protrusion has a minor arc surface. During the sliding adjustment of the baffle plate, the guiding effect of the arc surface allows the protrusion to smoothly disengage from or engage with the positioning groove, avoiding jamming and ensuring smooth operation.

[0025] In summary, this application includes the following beneficial technical effects: In this application, a sliding mounting plate is provided on the front side of the main body, and a protective plate is rotatably connected to the lower edge of the mounting plate, allowing the protective plate to flexibly switch between vertical protection and horizontal storage states. During transportation, the protective plate rotates to the vertical state to provide rigid protection for the cantilevered protruding lower connecting piece, avoiding damage caused by bumps during transportation; during installation, the protective plate rotates to the horizontal storage state and fits against the bottom of the main body, significantly reducing the overall size of the equipment and facilitating hoisting operations and column-mounted installation.

[0028] The present application will be further described in detail below with reference to all the accompanying drawings. Example

[0029] Reference Figure 1 and Figure 2 An outdoor intelligent integrated pole-mounted circuit breaker includes a main body 1, three poles 2 fixed on the top surface of the main body 1, an upper connecting piece 21 fixed on the top surface of the poles 2, a lower connecting piece 22 fixed on the outer periphery facing the front of the main body 1, a support plate 12 fixed on the two opposite edges of the bottom surface of the main body 1, a traction handle 11 rotatably connected to the left and right vertical sides, and a protective component 3 for protecting the lower connecting piece 22 is provided on the front vertical surface of the main body 1; the protective component 3 includes a mounting plate 31 that is horizontally arranged on the front of the main body 1 and can slide up and down (using dovetail slide rail and dovetail slide groove cooperation), a protective plate 32 rotatably connected to the lower edge of the mounting plate 31, and a locking member 4 and a positioning member 5 provided on the outside of the main body 1; During the transportation of the pole-mounted circuit breaker, the protective plate 32 is rotated to a vertically upward protective state and fixed by the positioning member 5. At this time, the protective plate 32 is located on the side of the lower terminal piece 22 away from the pole 2, thereby protecting the lower terminal piece 22. When the pole-mounted circuit breaker is installed and used, it is first lifted by the hoisting equipment through the traction handle 11, and then the protective plate 32 is rotated to a horizontal and stored state below the main body 1, and the protective plate 32 is fixed by the locking member 4, thereby reducing the volume during installation and use.

[0030] Reference Figure 2 and Figure 3 When the protective plate 32 is in the protective state, a barrier plate 33 is fixed on the top surface in the horizontal direction above the lower connector 22; when the protective plate 32 is in the protective state, the barrier plate 33 is used to protect the area above the lower connector 22. When the protective plate 32 is in the retracted state (i.e., when the pole-mounted circuit breaker is installed and applied), the bottom edge of the barrier plate 33 is flush with the bottom surface of the support plate 12. In this way, the combined structure of the barrier plate 33 and the protective plate 32 can further support the main body 1 and improve the installation stability of the pole-mounted circuit breaker.

[0031] Reference Figure 3 , Figure 4 and Figure 5 The locking component 4 includes two locking rods 41 that slide horizontally on the side of the pole post 2 and are coaxial when the protective plate 32 is in the protective state, and an elastic pressing component 42 set on the protective plate 32. Both support plates 12 are provided with locking through holes 121, and the outer edges of the ends of the two locking rods 41 that are far apart from each other are provided with guide slopes 411. When the protective plate 32 is in the retracted state, the elastic pressing component 42 drives the two locking rods 41 to slide in opposite directions. At this time, the locking rods 41 can be inserted into and pass through the locking through holes 121, thereby limiting and locking the protective plate 32 in the retracted state.

[0032] Reference Figure 6 The elastic compression member 42 includes a first spring 421 in a compressed state, a guide block 422 fixed on the protective plate 32, and a protruding plate 423 fixed on the outer periphery of the locking rod 41. The guide block 422 has a guide hole for the locking rod 41 to pass through. The outer periphery of the ends of the two locking rods 41 that are close to each other is fixed with an anti-detachment protruding plate 412. The protruding plate 423 is located on the side of the guide block 422 away from the anti-detachment protruding plate 412. The two ends of the first spring 421 are fixedly connected to the sides of the guide block 422 and the protruding plate 423 that are close to each other.

[0033] Reference Figure 6 , Figure 7 and Figure 8The positioning component 5 includes an elastic positioning rod 51 rotatably connected to the outer peripheral surface of the traction handle 11 at one end. The elastic positioning rod 51 is a conventional telescopic structure with an internal spring and elastic shortening performance, which will not be described in detail here. The end of the elastic positioning rod 51 away from the traction handle 11 is fixed with a positioning hook 52, and the ends of the two locking rods 41 that are far apart from each other are provided with locking holes 413. When the protective plate 32 is in the protective state, the traction handle 11 is turned to the vertical upward state, the elastic positioning rod 51 is turned to the horizontal state along the direction towards the protective plate 32, and the positioning hook 52 is engaged in the locking hole 413, thereby realizing the limit locking of the protective plate 32 in this state. When the protective plate 32 is in the retracted state, the traction handle 11 is turned to the vertical downward state, the locking rod 41 passes through the locking through hole 121, the elastic positioning rod 51 is turned to the vertical downward state, and the positioning hook 52 is engaged in the locking through hole 121 to further limit and lock the locking rod 41 in this state.

[0034] Reference Figure 8 , Figure 9 and Figure 10 The barrier plate 33 is provided with a clearance through hole 331. The main body 1 is provided with a connecting plate 6 that passes through the clearance through hole 331 and is parallel to the protective plate 32. When the protective plate 32 is in the protective state, the connecting plate 6 is provided with an upper anti-detachment plate 61 on its top surface and a lower anti-detachment plate 62 on its bottom surface. The upper anti-detachment plate 61 is provided with a traction ring 63 on its side away from the barrier plate 33. When the protective plate 32 is in the protected state (i.e., when the pole-mounted circuit breaker is being transported), the bottom surface of the upper anti-detachment plate 61 abuts against the top surface of the barrier plate 33, and the connecting plate 6 protects the locking rod 41 and the elastic pressing member 42 at this time; when the protective plate 32 is in the stored state (i.e., when the pole-mounted circuit breaker is being installed and used) and the pole-mounted circuit breaker is being inspected later, the staff can slide the upper anti-detachment plate 61 away from the barrier plate 33 by pulling the pull ring 63, and slide the connecting plate 6 out from under the protective plate 32. At this time, the top surface of the connecting plate 6 can be used to hold the disassembly and assembly tools.

[0035] Reference Figure 11 and Figure 12 An elastic snap-fit ​​member 34 is provided on the inner wall of the clearance through hole 331. The connecting plate 6 is evenly provided with a number of positioning grooves 64 for the elastic snap-fit ​​member 34 to snap into. When the connecting plate 6 slides along the clearance through hole 331, the elastic snap-fit ​​member 34 can snap into the corresponding positioning groove 64, thereby improving the installation stability of the connecting plate 6 in the corresponding state. The elastic snap-fit ​​component 34 includes a compression spring 341 and an arc-shaped protrusion 342. A placement groove 332 is provided on the inner wall of the clearance through hole 331 for the compression spring 341 and the arc-shaped protrusion 342 to be inserted. The compression spring 341 squeezes one side of the arc-shaped protrusion 342, causing a part of the arc-shaped protrusion 342 to protrude from the opening of the placement groove 332. The outer surface of the protruding part of the arc-shaped protrusion 342 is an arc surface, and the arc length corresponding to this arc surface is a minor arc.

[0036] The implementation principle of this application embodiment is as follows: During transportation, the protective plate 32 is rotated to the vertically upward protective state, the traction handle 11 is rotated to the vertically upward position, the elastic positioning rod 51 is rotated to the horizontal position, and the positioning hook 52 is engaged with the locking hole 413 of the locking rod 41 to achieve the limiting of the protective plate 32; the barrier plate 33 is located above the lower connecting piece 22, and the connecting plate 6 protects the locking rod 41 and the elastic pressing piece 42, jointly protecting the lower connecting piece 22 from damage.

[0037] During installation, the protective plate 32 is rotated to a horizontal storage state by using the hoisting equipment with the traction handle 11. The elastic compression member 42 drives the two locking rods 41 to slide back and forth, inserting into the locking through hole 121 of the support plate 12 to lock. At this time, the bottom surface of the barrier plate 33 is flush with the support plate 12, and together with the protective plate 32, it supports the main body 1, improving the installation stability. At the same time, the upper anti-detachment plate 61 of the connecting plate 6 abuts against the barrier plate 33.

[0038] During later maintenance, pulling the traction ring 63 causes the connecting plate 6 to slide out, and its top surface can hold disassembly and assembly tools; when the connecting plate 6 slides, the elastic locking piece 34 engages with the corresponding positioning groove 64 to ensure stability after adjustment. When switching between protective and storage states, the positioning piece 5 and the locking piece 4 work together to achieve flexible switching between protective and compact states.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
