Description

Technical Field

[0001] This application relates to the technical field of distribution cabinets, and particularly to a new energy adaptable high-voltage distribution cabinet. Background Art

[0002] High-voltage distribution cabinets are important equipment in the power system, mainly used for on-off, control, or protection in power generation, transmission, distribution, power conversion, and consumption. Their voltage levels are usually between 3.6 kV and 550 kV, covering a variety of electrical products, such as high-voltage circuit breakers, high-voltage disconnectors, high-voltage load switches, etc. The manufacturing and application of high-voltage distribution cabinets are of great significance for the stable operation of the power system. Therefore, the high-voltage switch manufacturing industry occupies an important position in the power transmission and transformation equipment manufacturing industry.

[0003] In the related art, a high-voltage distribution cabinet includes a cabinet body and a cabinet door hinged to the cabinet body. Ventilation openings are usually provided on the cabinet body to ensure heat dissipation and ventilation inside the cabinet body. In addition, many electrical components, such as current transformers, voltage transformers, lightning arresters, disconnectors, etc., are installed inside the cabinet body. These components play roles such as measurement, protection, isolation, and control in the power system.

[0004] In areas with abundant water vapor and humid air, such as coastal cities, since the ventilation openings are always open and cannot be automatically adjusted according to the environmental humidity; when the above-mentioned distribution cabinet is applied in coastal areas, excessive moisture is likely to enter the cabinet body through the ventilation openings; this will not only accelerate the corrosion rate of internal electrical components, but also may cause electrical failures, posing a threat to the stable operation of the power system, and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a new energy adaptable high-voltage distribution cabinet to solve the problem that when the above-mentioned distribution cabinet is applied in coastal areas, external moisture is likely to enter the cabinet body and accelerate the corrosion of electrical components.

[0006] A new energy adaptable high-voltage distribution cabinet provided by this application adopts the following technical solutions:

[0007] A new energy adaptable high-voltage distribution cabinet includes a cabinet body and a cabinet door hinged to the cabinet body. A plurality of heat dissipation openings are provided on two opposite vertical sides of the cabinet body; a protective cover with an opening facing outwards is fixedly provided on the outer opening edge of the heat dissipation opening. A plugging plate for plugging the heat dissipation opening is slidably provided on the inner wall of the cabinet body, and a driving member for driving the plugging plate to slide up and down is fixedly provided. A plugging hole that coincides with the heat dissipation opening is provided on the plugging plate, and the plugging hole can be misaligned with the heat dissipation opening when the plugging plate slides up and down.

[0008] By adopting the above technical solution, the power distribution cabinet controls the up-and-down sliding of the sealing plate through the driving member, realizes the effective sealing and opening of the heat dissipation port, and can adjust the ventilation state according to the change of the external environmental humidity. In a humid environment, the sealing plate slides to misalign the sealing hole and the heat dissipation port, effectively preventing moisture from entering the cabinet through the heat dissipation port, and avoiding the accelerated corrosion of electrical components and the occurrence of electrical faults. When the outside is dry, the sealing hole coincides with the heat dissipation port to ensure its heat dissipation performance. This design not only enhances the corrosion resistance of the power distribution cabinet, but also ensures the stable operation of the power system, reducing power outages and maintenance costs caused by equipment failures.

[0009] Optionally, a horizontal plate is provided horizontally below each of the plurality of protective covers, and vertical rods are fixedly provided vertically at both ends of the plurality of horizontal plates on the same side. A control rod is fixedly provided on the sealing plate, and a guiding through groove for the control rod to penetrate and slide up and down is opened on the cabinet body; a baffle for blocking the outer opening of the guiding through groove is fixedly provided on the outer circumference of the control rod and located outside the cabinet body, and a limiting notch for the lower side of the horizontal plate to be inserted is opened on the upper side surface of the outer end of the control rod; when the control rod slides up and down with the sealing plate, the horizontal plate is driven to slide synchronously, and when the horizontal plate slides upward, the lower opening of the protective cover can be blocked.

[0010] By adopting the above technical solution, when the sealing plate slides up and down, the horizontal plate is driven to slide synchronously through the control rod fixedly provided on the sealing plate, realizing the dynamic sealing and opening of the lower opening of the protective cover. In a humid environment, the horizontal plate slides upward, and by utilizing the structural advantages of itself and the vertical rod, the lower opening of the protective cover is tightly sealed, effectively preventing moisture from entering the cabinet through the gap, and further improving the moisture-proof effect of the power distribution cabinet. This design not only improves the corrosion resistance of the power distribution cabinet, but also ensures its stable operation in a harsh environment, providing a strong guarantee for the safe and reliable operation of the power system.

[0011] Optionally, a sealing gasket is fixedly provided on the side surface of the horizontal plate close to the protective cover.

[0012] By adopting the above technical solution, the sealing gasket fixedly provided on the horizontal plate can closely fit on the edge of the protective cover when the horizontal plate slides upward to block the lower opening of the protective cover, forming an effective moisture-proof barrier. This design not only enhances the moisture-blocking ability of the power distribution cabinet, but also effectively prevents the moisture penetration problem caused by the gap, further prolonging the service life of electrical components and improving the overall operation stability of the power distribution cabinet. At the same time, the sealing gasket is made of soft and wear-resistant material, has good elasticity and sealing performance, can adapt to the use requirements under different environmental conditions, and ensures the safe and reliable operation of the power distribution cabinet in various harsh environments.

[0013] Optionally, a locking rod is provided outside the cabinet body. An adjusting through hole for the locking rod to penetrate is formed in the vertical side surface of the cabinet body. An adjusting member for driving the locking rod to slide reciprocally along its own axis is arranged inside the cabinet body; two locking folding rods symmetrically sleeved on the outer periphery of the vertical rod are hinged to the outer end of the locking rod. A guiding inclined surface is arranged on the outer opening edge of the adjusting through hole. When the two locking folding rods slide inwardly along with the locking rod, they abut against the guiding inclined surface. During this process, the two slide toward each other and lock the vertical rod tightly.

[0014] By adopting the above technical solution, when the locking rod slides inwardly, the two locking folding rods at its outer end slide toward each other under the action of the guiding inclined surface and tightly lock the vertical rod, so as to limit the up-and-down sliding of the vertical rod, improving the overall safety performance and stability.

[0015] Optionally, the adjusting member includes an adjusting rod slidably arranged on the bottom side of the cabinet body along the horizontal direction of the connecting rod. The two ends of the connecting rod are respectively hinged to the outer peripheral surface of the adjusting rod and the inner end of the locking rod; when the cabinet door is closed, it can squeeze the connecting rod to slide away from the cabinet door. At this time, the two locking folding rods rotate toward each other; a first reset member for driving the adjusting rod to slide toward the cabinet door is also arranged inside the cabinet body.

[0016] By adopting the above technical solution, when the cabinet door is closed, it will squeeze the connecting rod, causing the adjusting rod to slide away from the cabinet door. This action, through the transmission of the connecting rod, makes the two locking folding rods rotate toward each other and tightly lock the vertical rod, thus realizing the automatic locking of the power distribution cabinet. At the same time, the first reset member arranged inside the cabinet body can drive the adjusting rod to slide toward the cabinet door when the cabinet door is opened, unlocking the locking folding rods, which is convenient for operation. This design not only simplifies the operation process, improves work efficiency, but also enhances the safety and convenience of the power distribution cabinet.

[0017] Optionally, when the cabinet door is opened, the two locking folding rods rotate away from each other and release the limit on the lower end of the vertical rod. At this time, the horizontal plate and the vertical rod can be taken down from the outer side surface of the cabinet body as a whole; the outer periphery of the upper horizontal plate can be clamped into the limiting notch on the lower control rod, and the horizontal plate and the vertical rod are in a state of being obliquely placed on the outer side surface of the cabinet body.

[0018] By adopting the above technical solution, when the cabinet door is opened, the two locking folding rods rotate away from each other, releasing the limit on the lower end of the vertical rod, so that the horizontal plate and the vertical rod can be easily taken down from the outer side surface of the cabinet body as a whole. This design allows users to reassemble the horizontal plate and the vertical rod according to needs. For example, the outer periphery of the uppermost horizontal plate can be clamped into the limiting notch of the lower control rod, making the horizontal plate and the vertical rod obliquely placed on the outer side surface of the cabinet body to form a convenient temporary ladder, which is convenient for maintenance personnel to perform maintenance or repair operations on the upper part of the power distribution cabinet. This innovation not only improves the versatility of the power distribution cabinet, but also greatly facilitates the repair operation, reduces the work difficulty, and improves work efficiency.

[0019] Optionally, a towing rope is provided outside the cabinet body. One end of the towing rope is fixedly arranged on the outer periphery of the vertical rod in an inclined state, and the other end is fixedly arranged on the outer end of the locking folding rod.

[0020] By adopting the above technical solution, the towing rope connects the vertical rod in an inclined state with the outer end of the locking folding rod, forming a stable triangular support structure. This structure is very stable mechanically and can prevent the vertical rod from tipping or sliding due to uneven stress in the inclined state. Such a design not only improves the safety of the power distribution cabinet when used as a ladder but also allows maintenance personnel to perform high-altitude operations more reassuringly, thereby improving the overall work efficiency.

[0021] Optionally, the first resetting member includes a first compression spring, a protruding plate fixedly arranged on the outer periphery of the adjusting rod, and a first positioning block fixedly arranged on the bottom side of the cabinet body. A first positioning hole for the adjusting rod to pass through is formed in the first positioning block. The first positioning block is located on the side of the protruding plate away from the cabinet body, and the two ends of the first compression spring are respectively fixedly connected to the mutually approaching sides of the protruding plate and the first positioning block.

[0022] By adopting the above technical solution, when the cabinet door is opened, the first compression spring pushes the protruding plate under the action of elastic force, and then drives the adjusting rod to slide towards the direction close to the cabinet door, unlocking the locking folding rod. Such a design not only ensures that the locking mechanism can automatically reset after the cabinet door is opened, preparing for automatic locking when the cabinet door is closed next time, but also improves the stability and durability of the entire locking mechanism. At the same time, this resetting method does not require external power, is energy-saving and environmentally friendly, and has a simple structure and is easy to maintain.

[0023] Optionally, a pushing plate is fixedly arranged on the inner side surface of the cabinet door, and the pushing plate presses the end of the adjusting rod close to the cabinet door when the cabinet door is closed.

[0024] By adopting the above technical solution, when the cabinet door is closed, it can directly press the end of the adjusting rod. This action makes the locking folding rods rotate towards each other through the transmission mechanism, realizing the locking of the vertical rod. Such a design not only simplifies the locking operation, enabling the user to complete the locking only by closing the cabinet door, but also improves the accuracy and reliability of locking. At the same time, the use of the pushing plate also enhances the linkage between the cabinet door and the locking mechanism, making the operation of the entire power distribution cabinet more smooth and coordinated, and improving the user experience.

[0025] Optionally, an elastic pad is fixedly arranged on the side of the pushing plate away from the cabinet door.

[0026] By adopting the above technical solution, the elastic pad fixedly arranged on the side of the pushing plate away from the cabinet door can play a role of buffering and shock absorption when the cabinet door is closed, effectively reducing the rigid impact on the adjusting rod and prolonging the service life of the adjusting rod and its related transmission components.

[0027] In summary, the present application includes the following beneficial technical effects:

[0028] The power distribution cabinet controls the up and down sliding of the sealing plate through a driving member, realizes the effective sealing and opening of the heat dissipation port, and can adjust the ventilation state according to the change of the external environmental humidity. In a humid environment, the sealing plate slides to misalign the sealing hole with the heat dissipation port, effectively preventing moisture from entering the cabinet through the heat dissipation port, and avoiding the accelerated corrosion of electrical components and the occurrence of electrical faults. When the outside is dry, the sealing hole coincides with the heat dissipation port to ensure its heat dissipation performance. This design not only enhances the corrosion resistance of the power distribution cabinet, but also ensures the stable operation of the power system, reducing power outages and maintenance costs caused by equipment failures.

Detailed implementation manners

[0038] The following further elaborates on the present application in conjunction with all the attached drawings.

[0039] Embodiment 1:

[0040] Referring to Figure 1 and Figure 2 , a new energy - adapted high - voltage power distribution cabinet includes a cabinet body 1 and a cabinet door 2 hinged to the cabinet body 1. On the other side of the cabinet door 2, it is detachably connected to the cabinet body 1 through a conventional lock structure; on two opposite vertical sides of the cabinet body 1, three heat dissipation openings 11 are respectively provided, which helps to dissipate the heat inside the power distribution cabinet and prevent damage or performance degradation of electrical components caused by excessive temperature.

[0041] Referring to Figure 2 , on the outer - opening edge of the heat dissipation opening 11, a protective cover 12 with an opening - facing direction is fixedly provided. On the inner wall of the cabinet body 1, a plugging component 3 is provided. The plugging component 3 includes a plugging plate 31 slidably arranged on the inner wall of the cabinet body 1 and a driving member 32 fixedly arranged on the inner wall of the cabinet body 1. A plugging hole 311 coinciding with the heat dissipation opening 11 is provided on the plugging plate 31. The driving member 32 is a vertically - arranged electric cylinder 321 for driving the plugging plate 31 to slide up and down.

[0042] When the electric cylinder 321 operates, it drives the plugging plate 31 to slide up and down. At this time, the plugging hole 311 on the plugging plate 31 can be misaligned or coincided with the heat dissipation opening 11. When it is humid outside, the plugging plate 31 blocks the heat dissipation opening 11 to prevent rainwater from entering the cabinet body 1. When it is dry outside, the plugging hole 311 coincides with the heat dissipation opening 11 to ensure its heat dissipation performance.

[0043] Referring to Figure 3 and Figure 4 , a cross plate 33 is horizontally arranged below each of the three protective covers 12. At both ends of the three cross plates 33 on the same side, a vertical rod 34 is fixedly arranged in the vertical direction together. A control rod 35 with the same number as the protective cover 12 is fixedly arranged on the plugging plate 31. A guiding through groove 13 for the control rod 35 to penetrate and slide up and down is provided on the cabinet body 1.

[0044] A baffle plate 351 is fixedly arranged on the outer periphery of the control rod 35 and is located outside the cabinet body 1 for blocking the outer opening of the guiding through groove 13. A limiting notch 352 for the lower side of the cross plate 33 to be inserted is formed on the upper side of the outer end of the control rod 35; and a sealing gasket 331 made of rubber is fixedly arranged on the side of the cross plate 33 close to the protective cover 12;

[0045] When the electric cylinder 321 operates to drive the plugging plate 31 to block the heat dissipation opening 11, the control rod 35 slides along with the plugging plate 31 to drive the cross plate 33 to slide synchronously. At this time, the cross plate 33 slides upward to use the sealing gasket 331 to block the lower opening of the protective cover 12; when the plugging hole 311 coincides with the heat dissipation opening 11, the cross plate 33 slides downward to release the blockage of the lower opening of the protective cover 12.

[0046] Refer to Figure 3 and Figure 5 As shown in FIGS. and, a locking assembly 4 is arranged outside the cabinet body 1. The locking assembly 4 includes a locking rod 41 and a locking folding rod 42. An adjusting through hole 14 for the locking rod 41 to penetrate is formed on the vertical side surface of the cabinet body 1. The outer end of the locking rod 41 is hinged to the same end of the two locking folding rods 42. The two locking folding rods 42 are symmetrically sleeved on the outer periphery of the vertical rod 34. A guiding inclined surface 141 is arranged on the edge of the outer opening of the adjusting through hole 14;

[0047] An adjusting member 5 for driving the locking rod 41 to slide reciprocally along its own axis is arranged inside the cabinet body 1; when the two locking folding rods 42 slide inward along with the locking rod 41, they abut against the guiding inclined surface 141. During this process, the two locking folding rods 42 slide towards each other and lock the vertical rod 34, so that the whole vertical rod 34 and the cross plate 33 can only slide up and down along the vertical direction; when the two locking folding rods 42 slide outward, the limit on the lower end of the vertical rod 34 is released.

[0048] Refer to Figure 5 and Figure 6 As shown in FIGS. and, the adjusting member 5 includes an adjusting rod 52 slidably arranged on the bottom side of the cabinet body 1 along the horizontal direction and a connecting rod 51. The two ends of the connecting rod 51 are respectively hinged to the outer peripheral surface of the adjusting rod 52 and the inner end of the locking rod 41; a pushing plate 21 is fixedly arranged on the inner side surface of the cabinet door 2, and an elastic pad 22 made of rubber is fixedly arranged on the side of the pushing plate 21 away from the cabinet door 2; a first reset member 53 for driving the adjusting rod 52 to slide towards the cabinet door 2 is further arranged inside the cabinet body 1;

[0049] When the cabinet door 2 is closed, the elastic force of the first reset member 53 is overcome. At this time, the elastic pad 22 on the pushing plate 21 presses against the end of the adjusting rod 52 close to the cabinet door 2. The sliding of the adjusting rod 52 drives the connecting rod 51 to swing. At this time, the two locking folding rods 42 rotate towards each other; when the cabinet door 2 is opened, the pushing plate 21 stops pressing against the outer end of the adjusting rod 52. Under the action of the first reset member 53, the adjusting rod 52 slides in the reverse direction, and the two locking folding rods 42 rotate away from each other, and the limit on the lower end of the vertical rod 34 is released;

[0050] Refer to Figure 5 Figure 5 , the first reset member 53 includes a first compression spring 531, a protruding plate 532 fixedly arranged on the outer periphery of the adjusting rod 52, and a first positioning block 533 fixedly arranged on the bottom side of the cabinet body 1. A first positioning hole for the adjusting rod 52 to penetrate is formed in the first positioning block 533. The first positioning block 533 is located on the side of the protruding plate 532 away from the cabinet body 1. Two ends of the first compression spring 531 are respectively fixedly connected to the side surfaces of the protruding plate 532 and the first positioning block 533 close to each other.

[0051] The implementation principle of the embodiment of the present application is as follows:

[0052] The power distribution cabinet realizes the dynamic blocking and opening of the heat dissipation port 11 through the blocking plate 31 driven by the electric cylinder 321 to adapt to the humidity change of the external environment, ensure the heat dissipation performance of the power distribution cabinet and prevent rainwater from invading. When the outside is humid, the electric cylinder 321 drives the blocking plate 31 to slide, so that the blocking hole 311 is misaligned with the heat dissipation port 11. At the same time, the control rod 35 drives the sealing gasket 331 on the cross plate 33 and the vertical rod 34 to block the lower opening of the protective cover 12, enhancing the protection effect. When the cabinet door 2 is closed, the elastic pad 22 on the push plate 21 squeezes the adjusting rod 52, and drives the locking folding rod 42 to lock the vertical rod 34 through the connecting rod 51, ensuring the stability of the blocking structure; when the cabinet door 2 is opened, the first reset member 53 resets the adjusting rod 52, and the locking folding rod 42 is unlocked, facilitating operation.

[0053] Embodiment 2:

[0054] Refer to Figure 7 Figure 7 , the difference between the embodiment of the present application and Embodiment 1 is that when the cabinet door 2 is opened, the two locking folding rods 42 rotate away from each other and release the limit on the lower end of the vertical rod 34. At this time, the cross plate 33 and the vertical rod 34 as a whole can be removed from the outer side surface of the cabinet door 2, and then the outer periphery of the uppermost cross plate 33 is snapped into the limit notch 352 on the lower control rod 35. The cross plate 33 and the vertical rod 34 are in a state of being obliquely arranged on the outer side surface of the cabinet body 1;

[0055] A traction rope 6 is arranged outside the cabinet body 1. One end of the traction rope 6 is fixedly arranged on the outer periphery of the vertical rod 34, and the other end is fixedly arranged on the outer end of the locking folding rod 42; the traction rope 6 is used to limit the cross plate 33 and the vertical rod 34 as a whole in an inclined state. The cross plate 33 and the vertical rod 34 in this state form an obliquely installed "ladder", which is convenient for overhauling the upper part of the cabinet body 1.

[0056] The implementation principle of the embodiment of the present application is as follows:

[0057] When the cabinet door 2 is opened, the two locking folding rods 42 unlock the vertical rod 34, allowing the horizontal plate 33 and the vertical rod 34 to be removed from the outer side of the cabinet body 1 as a whole and reassembled into an inclined "ladder" structure, which facilitates maintenance personnel to climb to the upper part of the cabinet body 1 for maintenance operations. This design not only improves the practicability of the power distribution cabinet but also optimizes the maintenance efficiency. At the same time, through the traction rope 6 provided, one end is connected to the vertical rod 34 and the other end is connected to the control rod 35, ensuring the overall stability of the horizontal plate 33 and the vertical rod 34 in the inclined state and preventing accidental slipping, further ensuring the safety of maintenance personnel.
