Description

Technical Field

[0001] This invention belongs to the field of transformer cabinet technology, specifically relating to a device for preventing the backflow of high-temperature airflow inside a high-voltage cabinet, and more particularly to a high-voltage cabinet control system and control method. Background Technology

[0002] High-voltage switchgear typically relies on the combined action of cooling fans and exhaust vents to achieve forced ventilation and heat dissipation, maintaining the normal operating temperature of the electrical components inside the cabinet. To prevent external dust and foreign objects from entering the cabinet, a filter is usually installed at the exhaust vent.

[0003] In related technologies, filtration devices often employ a fixed structure. During long-term operation of the high-voltage switchgear, oxide particles or metal shavings are generated, leading to a significant accumulation of fine particulate matter on the surface of the filter. This increases ventilation resistance and affects heat dissipation efficiency. When the high-voltage switchgear is shut down, the cooling fan stops working, and airflow exchange between the switchgear and the outside ceases. At this time, a heat stagnation zone forms at the top of the enclosure due to poor air circulation. This heat gradually flows back down to the inner wall of the high-voltage switchgear, causing abnormally high local temperatures inside the switchgear, accelerating the aging of insulation materials, and reducing the reliability of equipment operation.

[0004] Therefore, how to prevent the backflow of heat trapped in the exhaust port is a technical problem that urgently needs to be solved.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0014] In one optional embodiment, the filter plate of the flip-type filter mechanism has three working states when it flips. First working state: The first side of the filter plate is facing upwards; Second working state: The flip-type filter mechanism moves upward along the vertical direction of the cover until the filter plate is in a vertical state, and the filter plate is cleaned by the cooling fan; In the third working state, the first side of the filter plate is set downwards.

[0015] Secondly, this disclosure also provides a control method employing the high-voltage switchgear control system described above, the control method comprising: The high-voltage switchgear itself has stopped working; The flip-type filter mechanism is pushed upward along the vertical direction of the cover by external force; Disturb the gas in the heat retention zone at the top of the enclosure; When the external force is released, the flip-type filter mechanism relies on gravity to descend and reset, causing the filter plate to flip over, so as to clean the fine particles on the filter plate.

[0016] In one optional embodiment, the filter plate of the flip-type filter mechanism has three working states when it flips. First working state: The first side of the filter plate is facing upwards; Second working state: The flip-type filter mechanism moves upward along the vertical direction of the cover until the filter plate is in a vertical state, and the filter plate is cleaned by the cooling fan; In the third working state, the first side of the filter plate is facing downwards; During the process of pushing the tilting filter mechanism upward along the vertical direction of the cover by external force, the control method in the high-voltage cabinet control system also includes: The filter plate is in a vertical position, and a cooling fan cleans the filter plate.

[0017] The beneficial effects of this invention are that the high-voltage switchgear control system and its control method, by setting a flip-type filter mechanism that can slide up and down inside the enclosure and pushing it upward by external force when the machine stops, can effectively disturb the gas in the heat retention area at the top of the enclosure and disrupt the conditions for hot gas recirculation, thereby avoiding local temperature rise inside the cabinet and slowing down the aging of insulation materials. At the same time, after the filter plate is flipped, it is easy to clean the fine particles on the filter plate, thereby reducing the ventilation resistance and heat accumulation problems caused by filter plate blockage during the next operation.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present.

[0026] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0029] Studies have found that most filter devices employ a fixed structure. During long-term operation of the high-voltage switchgear, oxide particles or metal shavings are generated, leading to a buildup of fine particulate matter on the filter surface. This increases ventilation resistance and reduces heat dissipation efficiency. When the high-voltage switchgear is shut down, the cooling fan stops working, and airflow exchange between the switchgear and the outside ceases. At this time, a heat stagnation zone forms at the top of the enclosure due to poor air circulation. This heat gradually flows back down to the inner wall of the high-voltage switchgear, causing abnormally high local temperatures inside the switchgear, accelerating the aging of insulation materials, and reducing the reliability of equipment operation.

[0030] Based on the above research, this disclosure provides a method to effectively disturb the gas in the heat retention zone at the top of the enclosure 200 by setting a flip-type filter mechanism 300 that can slide up and down inside the enclosure 200 and pushing it upward with external force when the machine stops, thereby disrupting the conditions for hot gas recirculation, thus avoiding local temperature rise inside the cabinet and slowing down the aging of the insulation material. At the same time, after the filter plate 310 is flipped, it is easy to clean the fine particles on the filter plate 310, thereby reducing the ventilation resistance and heat accumulation problems caused by the filter plate 310 being blocked during the next operation.

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please see Figure 1 and Figure 2 At least one embodiment provides a high-voltage switchgear control system, including: a high-voltage switchgear body 100, with an exhaust port 110 provided on its side wall; a cover 200 provided on the exhaust port 110; a flip-type filter mechanism 300 slidably disposed in the cover 200 along the vertical direction; a cooling fan disposed in the high-voltage switchgear body 100 and disposed opposite to the exhaust port 110; when the high-voltage switchgear body 100 is stopped, the flip-type filter mechanism 300 is pushed upward along the vertical direction of the cover 200 by an external force to disturb the gas in the heat retention area at the top of the cover 200; when the external force is released, the filter plate 310 of the flip-type filter mechanism 300 is flipped to facilitate the cleaning of fine particles on the filter plate 310 and reduce the heat accumulation in the heat retention area at the top of the cover 200 during the next operation.

[0035] By installing a sliding, flip-type filter mechanism 300 inside the enclosure 200, and pushing it upwards by external force when the machine stops, the gas in the heat retention area at the top of the enclosure 200 can be effectively disturbed, and the conditions for hot gas recirculation can be disrupted. This avoids local temperature rise inside the cabinet and slows down the aging of the insulation material. At the same time, after the filter plate 310 is flipped, it is easy to clean the fine particles on the filter plate 310, thereby reducing ventilation resistance and heat accumulation problems caused by filter plate 310 blockage during the next operation.

[0036] Please see Figure 2 and Figure 3 The flip-type filter mechanism 300 includes: a lifting frame 320; and a filter plate 310, which is rotatably disposed in the lifting frame 320 via a linkage flipping component 330. The outer wall of the lifting frame 320 is slidably connected to the inner wall of the inner cavity of the cover 200. When the lifting frame 320 moves upward along the vertical direction of the cover 200, it drives the linkage flipping component 330 to move upward and flip the filter plate 310.

[0037] Specifically, a trigger rod 210 is provided at the top of the inner cavity of the cover 200; when the lifting frame 320 moves upward along the vertical direction of the cover 200, the trigger rod 210 drives the linkage flipping component 330 to flip the filter plate 310.

[0038] When the lifting frame 320 rises to the top, the trigger rod 210 and the linkage flipping component 330 mechanically collide to achieve automatic flipping of the filter plate 310 without the need for an additional power source or manual operation. At the same time, by raising the lifting frame 320, the hot airflow in the heat retention area can be better disturbed.

[0039] The linkage flipping component 330 includes two sets of linkage rods, which are respectively disposed on both sides of the filter plate 310. Each set of linkage rods includes a driven rod 331, one end of which is rotatably connected to the lifting frame 320 and the other end of which is rotatably connected to the side wall of the filter plate 310; and a driving rod 332, one end of which is rotatably connected to the middle of the filter plate 310 and the other end of which is rotatably connected to the upper part of the lifting frame 320. When the lifting frame 320 moves upward along the vertical direction of the cover 200, it drives the driving rod 332 to touch the trigger rod 210, thereby completing the flipping of the filter plate 310.

[0040] After the drive rod 332 touches the trigger rod 210, it drives the filter plate 310 to rotate around the hinge point. The driven rod 331 plays an auxiliary guiding and stabilizing role, so that the rotation process of the filter plate 310 is smooth and the trajectory is controllable, avoiding jamming or incomplete rotation, and further ensuring the reliability and consistency of the rotation of the filter plate 310, thereby ensuring the cleaning effect.

[0041] It should be noted that the hinge point between the driven rod 331 and the lifting frame 320 is located directly below the hinge point between the driving rod 332 and the filter plate 310; both the hinge point between the driven rod 331 and the filter plate 310 and the hinge point between the driving rod 332 and the lifting frame 320 are located close to one end of the filter plate 310.

[0042] The inner wall of the lifting frame 320 is provided with a support block 333 on the opposite side; the filter plate 310 after being flipped is attached to the support block 333 through the hinge shaft of the drive rod 332.

[0043] Please see Figure 2 and Figure 4 The filter plate 310 includes: an outer frame 311; an insertion port 311a is provided on the side wall of the outer frame 311; a filter screen 312 is inserted into the outer frame 311 through the insertion port 311a; and a pick-and-place port 220 is provided at the fitting point between the cover 200 and the insertion port 311a to facilitate maintenance of the filter screen 312.

[0044] By designing the filter plate 310 as a separate structure consisting of an outer frame 311 and a removable filter screen 312, and providing a corresponding access port 220 on the cover 200, the filter screen 312 can be further cleaned when it is pulled out. This enables quick disassembly and individual maintenance of the filter screen 312, allowing for replacement or cleaning of the filter screen 312 without disassembling the entire flip-type filter mechanism 300.

[0045] The filter plate 310 of the flip-type filter mechanism 300 has three working states when it is flipped. Please see Figure 5In the first working state: the first surface of the filter plate 310 is facing upwards. When flipping, the trigger rod 210 drives the drive rod 332 away from the end of the filter plate 310 along... Figure 5 The direction of F1 is downward, so that the two ends of the filter plate 310 are respectively along... Figure 5 Rotate in the directions shown by F2 and F3 to complete the state switch.

[0046] Please see Figure 6 Second working state: The flip-type filter mechanism 300 moves upward along the vertical direction of the cover 200 until the filter plate 310 is in a vertical state, and the cooling fan cleans the filter plate 310. During flipping, the trigger rod 210 continues to drive the end of the drive rod 332 away from the filter plate 310 along... Figure 6 The direction of F1 is downward, so that the two ends of the filter plate 310 are respectively along... Figure 6 Rotate the squares shown in F2 and F3 to complete the state switch.

[0047] Please see Figure 7 In the third working state, the first side of the filter plate 310 is set downwards, completing the flipping of the filter plate 310.

[0048] Please see Figure 8 At least one embodiment also provides a control method using the high-voltage switchgear control system described above. By setting a tilting filter mechanism 300 that can slide up and down inside the enclosure 200, and pushing it upward by external force when the machine stops, the gas in the heat retention area at the top of the enclosure 200 can be effectively disturbed, and the conditions for hot gas recirculation can be disrupted, thereby avoiding local temperature rise inside the cabinet and slowing down the aging of the insulation material. At the same time, after the filter plate 310 is tilted, it is easy to clean the fine particles on the filter plate 310, thereby reducing the ventilation resistance and heat accumulation problems caused by the filter plate 310 being blocked during the next operation.

[0049] Specifically, the control method includes: S110: The high-voltage switchgear body stops working at 100°. S120: The flip-type filter mechanism 300 is pushed upward along the vertical direction of the cover 200 by external force; S130: Disturbing the gas in the heat retention zone at the top of the cover 200; S140: When the external force is released, the flip-type filter mechanism 300 descends and resets by gravity and inertia, driving the filter plate 310 to complete the flip-over, so as to clean the fine particles on the filter plate 310.

[0050] The filter plate 310 of the flip-type filter mechanism 300 has three working states when it is flipped. First working state: The first surface of the filter plate 310 is facing upwards; Second working state: The flip-type filter mechanism 300 moves upward along the vertical direction of the cover 200 until the filter plate 310 is in a vertical state, and the filter plate 310 is cleaned by the cooling fan; In the third working state, the first side of the filter plate 310 is set facing downwards; During the process of the flip-type filter mechanism 300 moving upward along the vertical direction of the cover 200 by external force, the control method of the high-voltage cabinet control system also includes: The filter plate 310 is in a vertical position, and the filter plate 310 is cleaned by a cooling fan.

[0051] The beneficial effects of this invention are that the high-voltage switchgear control system and its control method, by setting a flip-type filter mechanism 300 that can slide up and down inside the cover 200 and pushing it upward by external force when the machine stops, can effectively disturb the gas in the heat retention area at the top of the cover 200, disrupt the conditions for hot gas recirculation, thereby avoiding local temperature rise inside the cabinet and slowing down the aging of the insulation material. At the same time, after the filter plate 310 is flipped, it is easy to clean the fine particles on the filter plate 310, thereby reducing the ventilation resistance and heat accumulation problems caused by the filter plate 310 clogging during the next operation.

[0052] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0053] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0054] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0055] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0056] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
