Dustproof box transformer with ventilation function

Abstract

This invention discloses a dustproof transformer substation with ventilation function, relating to the field of transformer substation technology. It includes a frame, with ventilation doors at both ends of the transformer compartment and on one side of the high-voltage and low-voltage compartments, each with an air inlet. Multiple ventilation doors have flow guiding mechanisms installed on their inner lower sides, corresponding to the air inlets. The flow guiding mechanisms on the inner sides of the ventilation doors use elastic telescopic plates to press against the bottom of the equipment casing, forcibly guiding external cold air to the bottom of the equipment, forming a bottom-up cooling airflow that penetrates the entire equipment. This solves the problem of airflow diffusion and ineffective cooling of key heat-generating areas in traditional cooling solutions. The top cover cooling fan is linked with the flip-up flow guiding plate and the opening / closing plate, intelligently switching between independent and linked cooling modes based on the temperature thresholds of the high-voltage and low-voltage compartments. During non-high-temperature periods, forced ventilation is only applied to the transformer compartment; during high-temperature periods, the connecting holes are opened to achieve full-area cooling, ensuring effective cooling while reducing energy consumption, thus balancing energy efficiency and intelligent requirements.

Description

Technical Field

[0001] This invention relates to the field of transformer substation technology, specifically a dustproof transformer substation with ventilation function. Background Technology

[0002] In the field of power transmission and distribution, prefabricated substations are widely used in urban and rural power grids due to their advantages such as integration and small footprint. The transformers, high-voltage cabinets, low-voltage cabinets and other equipment inside the prefabricated substations generate a lot of heat during operation. Therefore, efficient heat dissipation is crucial to ensuring the stable operation of the equipment. At present, the conventional heat dissipation solution is to install a cooling fan on the top of the prefabricated substation and open an air inlet at the bottom of the box door, using the fan to draw air to form a "bottom in, top out" airflow circulation.

[0003] However, this solution has significant drawbacks. There is a spatial gap between the air inlet at the bottom of the enclosure door and the bottom of the equipment inside the enclosure. Furthermore, the layout of the equipment inside the enclosure is complex. When the top fan is drawing air, the external airflow enters the transformer and, due to the lack of effective guidance and constraint, it is difficult to flow directly to the bottom of the equipment. A large amount of airflow diffuses laterally in the gap between the enclosure door and the equipment, failing to form a cooling airflow that runs from the bottom of the equipment upwards through the entire equipment. This results in heat accumulation in the critical heat-generating areas of the equipment, which cannot be dissipated in time. Under long-term operation, the excessively high equipment temperature will not only accelerate insulation aging and reduce performance, but may even cause equipment failure, seriously affecting the reliability and stability of power supply. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a dustproof transformer substation with ventilation function to solve the technical problems mentioned above in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dustproof transformer box with ventilation function, comprising a frame, wherein a partition frame installed inside the frame divides the space inside the frame into a transformer room, a high-voltage room and a low-voltage room, and ventilation box doors with air inlets are movably connected to both ends of the transformer room and one side of the high-voltage room and the low-voltage room. Multiple sets of ventilation box doors are equipped with air guiding mechanisms corresponding to the air inlets. The fixed plate of the air guiding mechanism is fixed to the inside of the ventilation box door, and the elastic telescopic plate and the fixed plate are elastically slidably connected, which plays a role in elastically abutting against the equipment shell, so that the cold air can form a ventilation and heat dissipation airflow from the bottom of the equipment upward through the entire equipment. The top of the frame is equipped with a top cover, and a heat dissipation fan is installed in the middle of the inside of the top cover. The airflow guiding mechanism inside the ventilation box door presses against the bottom of the equipment shell with an elastic telescopic plate, forcing the outside cold air to the bottom of the equipment, forming a heat dissipation airflow that runs from bottom to top through the entire equipment. This solves the problem of airflow diffusion and ineffective cooling of key heat-generating areas in traditional heat dissipation solutions, delays insulation aging and improves operational stability. The partition frame has connecting holes on both sides that connect to the interior of the high-pressure chamber and the low-pressure chamber. The partition frame is also slidably connected to the two sides of the interior with opening and closing plates that cooperate with the connecting holes. The cooling fan is movably connected to both sides with rotating guide plates. When the rotating guide plates are rotated, their ends can drive the opening and closing plates to open and close the connecting holes. The flow guiding mechanism also includes a dust filter plate, a flow guide plate, and a fan wheel. The dust filter plate and the fixed plate are elastically slidably connected. Multiple sets of flow guide plates are fixed at intervals on the inner side of the fixed plate, and multiple sets of fan wheels are rotatably connected between every two sets of flow guide plates. The fan wheel rotates under the action of airflow, which beats the dust filter plate to remove dust. The dust filter plate in the flow guiding mechanism works with the rotation of the fan wheel to achieve a self-cleaning function. The fan wheel blades beat the filter plate to shake the dust off into the dust collection bag, reducing the frequency of manual cleaning. The flow guiding mechanism also includes a first spring frame and a second spring frame. Both sides of the fixed plate and the elastic telescopic plate are elastically connected by the first spring frame. The first spring frame plays the role of elastic sliding of the elastic telescopic plate relative to the fixed plate. The four corners of the fixed plate and the dust filter plate are elastically connected by the second spring frame. The second spring frame plays the role of elastic sliding of the dust filter plate relative to the fixed plate. Both ends of the high-pressure chamber and the low-pressure chamber are movably connected to side doors, and both the side doors and the ventilation box doors are equipped with locking mechanisms for locking and unlocking the doors. The top cover and the cooling fan are fixedly connected by a connecting frame. The connecting frame has fixed frames at both ends, and the two sets of flip guide plates and the fixed frames are rotatably connected by a rotating shaft. A flip rod is fixed on the outside of each set of rotating shafts. Electric push rods are installed obliquely on both sides of the two sets of fixed frames, and the output end of the electric push rod is movably connected to the flip rod. The top of the opening and closing plate is fixed with a sliding frame that is slidably connected to the partition frame, and the inner side of the sliding frame is provided with a groove corresponding to the flip guide plate; The top cover is equipped with a top exhaust hood located above the cooling fan, and exhaust pipes are connected to the four corners of the top exhaust hood. The top cover has first exhaust holes at both ends that cooperate with the exhaust pipes, and second exhaust holes on both sides of the top cover that are respectively connected to the high-pressure chamber and the low-pressure chamber.

[0006] By adopting the above technical solution, the top cover heat dissipation fan is linked with the flip guide plate and the opening and closing plate. It can intelligently switch between "independent heat dissipation" and "linked heat dissipation" modes according to the temperature threshold of the high-pressure chamber and the low-pressure chamber. During non-high-temperature periods, only the transformer chamber is forced to be ventilated. During high-temperature periods, the connecting holes are opened to achieve heat dissipation throughout the entire area. This reduces energy consumption while ensuring heat dissipation effect, taking into account both energy saving and intelligent requirements.

[0007] Furthermore, the flow guiding mechanism also includes a dust collection bag and a baffle, with the dust collection bag located at the bottom of the dust filter plate, and the top opening of the dust collection bag and the fixing plate and dust filter plate being detachably connected, and an inclined baffle is fixed at the top inside the dust collection bag.

[0008] By adopting the above technical solution, the baffle design avoids dust from being stirred up inside the dust collection bag, ensuring clean air intake.

[0009] In summary, the present invention has the following beneficial effects: The airflow guiding mechanism inside the ventilation box door of the present invention uses an elastic telescopic plate to press against the bottom of the equipment shell, forcibly guiding the outside cold air to the bottom of the equipment, forming a heat dissipation airflow that runs from bottom to top through the entire equipment. This solves the problem of airflow diffusion and ineffective cooling of key heat-generating areas in traditional heat dissipation solutions, delays insulation aging and improves operational stability. The dust filter plate inside the airflow guiding mechanism works with the rotation of the impeller to achieve a self-cleaning function. The impeller blades beat the filter plate to shake the dust off into the dust collection bag, reducing the frequency of manual cleaning. At the same time, the baffle design prevents dust from being stirred up inside the dust collection bag, ensuring clean air intake. In addition, the top cover heat dissipation fan is linked with the flipping airflow guiding plate and the opening and closing plate, which can intelligently switch between "independent heat dissipation" and "linked heat dissipation" modes according to the temperature threshold of the high-voltage room and the low-voltage room. During non-high-temperature periods, only the transformer room is forced to exhaust air, while during high-temperature periods, the connecting holes are opened to achieve full-area heat dissipation, reducing energy consumption while ensuring heat dissipation effect, and taking into account both energy saving and intelligent requirements.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0013] The embodiments of the present invention will now be described.

[0014] Example 1 like Figure 1-10 As shown, this embodiment focuses on a dustproof box transformer with ventilation function. Its structural design focuses on zoned heat dissipation, airflow guidance and intelligent control. It is mainly composed of components such as frame 1, partition frame 2, ventilation box door 7, airflow guiding mechanism 6 and heat dissipation fan 12. The interior of frame 1 is divided into a transformer room 3 in the middle and high-voltage room 4 and low-voltage room 5 on both sides by a partition frame 2, where transformers, high-voltage cabinets and low-voltage cabinets are installed respectively. Two opposing ventilation box doors are installed at both ends of the transformer room and on one side of the high-voltage room and the low-voltage room. An air inlet hole 8 is opened at the bottom of the door, and a flow guiding mechanism 6 is installed on the lower inner side. A cooling fan 12 is installed on the top of the top cover 10 and fixed by a connecting bracket 11. Flip-up guide plates 14 are provided on both sides, and the bottom is linked to the communication hole 18 of the partition frame 2 for control. The fixed plate 601 is fixed to the inside of the ventilation box door, and the elastic telescopic plate 602 is elastically connected to the fixed plate through the first spring frame 603. When the box door is closed, it presses against the bottom of the equipment shell and guides the airflow to flow upward from the bottom of the equipment. The dust filter plate 604 is elastically and slidably connected to the fixed plate via the second spring frame 607. When the airflow passes through, it drives the impeller 606 to rotate, which beats the filter plate and shakes off the dust. The dust falls into the bottom dust collection bag 608, and the baffle 609 inside the bag prevents dust from being stirred up. A guide plate 605 is provided on the inner side of the fixed plate, and a fan wheel 606 is installed between adjacent guide plates to guide the airflow evenly through the bottom of the equipment, forming a "bottom in and top out" heat dissipation path; The rotating shaft 15 is driven to rotate by the electric push rod 17. When it is flipped, the end pushes the sliding frame 19, which controls the opening and closing plate 20 to open or close the connecting hole 18 of the partition frame. Independent heat dissipation: By default, the cooling fan 12 only forces air to the transformer chamber 3, while the high-voltage chamber 4 and low-voltage chamber 5 are naturally convected through the corresponding air inlet 8 and the second exhaust 24, saving the power energy required by the cooling fan 12. Linked heat dissipation: When the temperature of high pressure chamber 4 and low pressure chamber 5 exceeds the threshold, the electric push rod 17 drives the flip guide plate 14 to open the connecting hole 18, and the cooling fan 12 simultaneously forces air to the three chambers to improve heat dissipation efficiency. Independent cooling mode for daily operation Door closing and airflow guidance: When the ventilation box door 7 is closed, the elastic telescopic plate 602 presses against the bottom of the equipment shell, and the dust filter plate 604 filters the dust in the airflow through the air inlet hole 8; Transformer room heat dissipation: When the cooling fan 12 is started, the hot air in the transformer room 3 is drawn out through the top exhaust hood 21 and exhaust pipe 22 and discharged from the first exhaust hole 23. The cold air from the outside is forced to be guided to the bottom of the transformer through the air inlet 8 and the guide mechanism 6, absorbing heat from bottom to top. Natural convection between high and low pressure chambers: Cold air is introduced into the high pressure chamber 4 and the low pressure chamber 5 through the air inlet 8, and hot air is naturally discharged from the second exhaust port 24, forming vertical convection by utilizing the principle of "heat rises and cold falls"; High-temperature emergency linkage heat dissipation mode Temperature trigger: When the temperature sensor of high-voltage chamber 4 or low-voltage chamber 5 detects that the temperature exceeds the set value, the control system activates the corresponding side electric push rod 17. At this time, only high-voltage chamber 4 or low-voltage chamber 5 can be connected to transformer chamber 3, or high-voltage chamber 4, low-voltage chamber 5 and transformer chamber 3 can be connected at the same time. Opening of the connecting hole: The electric push rod 17 pushes the flip rod 16, which drives the flip guide plate 14 to flip and lift the sliding frame 19. The opening and closing plate 20 moves up to open the connecting hole 18, so that the two or three interiors are connected. Forced ventilation throughout the entire area: When the cooling fan 12 simultaneously exhausts air into the three chambers, the air guiding mechanism 6 guides the cold air to flow upward from the bottom of the equipment, while the hot air is uniformly discharged from the top, quickly reducing the overall temperature. Maintenance and cleaning Dust filter plate cleaning: Regularly disassemble the dust collection bag 608 to remove dust, and use the second spring frame 607 to elastically shake the dust filter plate to help clean the attached impurities; Electric push rod adjustment: Check the linkage accuracy between the flip guide plate 14 and the opening and closing plate 20 to ensure that the connecting hole 18 opens quickly at high temperature and avoid heat dissipation delay.

[0015] The working principle of this invention is as follows: When in use, the equipment transformer box is installed in the designated location according to the construction specifications. The internal space of the frame 1 is divided into a transformer room 3 in the middle, and a high-voltage room 4 and a low-voltage room 5 on both sides by a partition frame 2. The transformer room 3 is equipped with a transformer, and the high-voltage room 4 and the low-voltage room 5 are equipped with a high-voltage cabinet and a low-voltage cabinet respectively. The transformer, the high-voltage cabinet and the low-voltage cabinet are interconnected with each other by cables in accordance with the regulations. Among them, the ventilation box doors 7 at both ends of the transformer room 3 are equipped with a flow guiding mechanism 6 corresponding to the air inlet 8, and the ventilation box doors 7 on the high voltage room 4 and the low voltage room 5 are also equipped with a flow guiding mechanism 6 corresponding to the air inlet 8. Specifically, the elastic telescopic plate 602 of the flow guiding mechanism 6 can passively and elastically extend and retract relative to the fixed plate 601. That is to say, when the ventilation box door 7 is closed, the end of the elastic telescopic plate 602 can abut against the lower part of the outer side of the transformer, high voltage cabinet and low voltage cabinet. At the same time, the elastic telescopic plate 602 passively extends and retracts, so as to adapt to different distances of flow guiding and not affect the normal closing of the ventilation box door 7. When ventilation and heat dissipation are required, the cooling fan 12 is started. The cooling fan 12 first generates suction in the transformer room 3. At this time, the outside air acts on the guide mechanism 6 through the air inlet 8. The guide mechanism 6 is movably connected to a dust filter plate 604. The dust filter plate 604 can filter and adsorb dust in the air to prevent external impurities from entering and affecting the normal operation of the equipment. Meanwhile, when the airflow passes through the dust filter plate 604, the airflow will act on the impeller 606. Under the action of the airflow, the impeller 606 will rotate passively. When the impeller 606 rotates, the multiple sets of blades on its outer side will beat one side of the dust filter plate 604 in turn. Then, the dust filter plate 604 and the fixed plate 601 will vibrate elastically through the second spring frame 607, so that the dust attached to the dust filter plate 604 can be shaken off, realizing the self-cleaning function of the dust filter plate 604 and reducing the replacement and cleaning cycle of the dust filter plate 604. The dust that falls off will enter the dust collection bag 608 for centralized collection. When the dust filter plate 604 needs to be replaced and cleaned, the staff can disassemble and clean the dust collection bag 608, the fixing plate 601, and the dust filter plate 604, making it more convenient to use. Meanwhile, a baffle 609 is inclinedly installed inside the dust collection bag 608. The inclination angle of the baffle 609 can better allow the incoming gas to pass directly through the dust filter plate 604 into the equipment room, avoiding the problem of airflow entering the dust collection bag 608 and causing dust. Since the elastic telescopic plate 602 of the flow guiding mechanism 6 abuts against the lower part of the outer side of the transformer, high voltage cabinet and low voltage cabinet, most of the incoming airflow can be forcibly guided to the bottom of the equipment, and then rise from the bottom of the equipment to absorb the heat of the equipment in all directions and then be discharged to the outside through the cooling fan 12. At this time, the hot airflow is discharged to the outside through the top exhaust hood 21 and the two sets of exhaust pipes 22 through the first exhaust hole 23. Based on the characteristics of the equipment, the transformer, high-voltage switchgear, and low-voltage switchgear inside the transformer substation typically generate the most heat during operation. In addition, the transformer converts AC power of one voltage level to AC power of another voltage level. During the energy conversion process, due to factors such as winding resistance, core hysteresis, and eddy currents, a large amount of energy loss will occur, and these losses will be dissipated in the form of heat. The high-voltage switchgear and low-voltage switchgear mainly distribute and control electrical energy. Although the switches, busbars, and other components inside them also have a certain resistance and generate heat when current flows through them, the overall loss is relatively small. In other words, the heat dissipation system of this equipment first performs forced ventilation and heat dissipation operation on the transformer chamber 3 through the cooling fan 12. At this time, the high-voltage chamber 4 and the low-voltage chamber 5 mainly perform heat exchange operation through natural flow. Natural convection occurs between the air inlet 8 and the second exhaust 24 of the ventilation box door 7 corresponding to the high-voltage chamber 4 and the low-voltage chamber 5. The hot air inside rises and is discharged to the outside through the second exhaust 24. At this time, the cold air enters the room through the air inlet 8 at the bottom to form a convection effect. Utilizing the principle of "heat rises and cold falls", the cold air naturally sinks into the box, and the hot air is discharged from the top, forming vertical convection. When the built-in temperature sensors of the high-pressure chamber 4 and the low-pressure chamber 5 detect that the internal temperature has reached the set value, the four sets of electric push rods 17 are activated. Every two sets of electric push rods 17 extend and drive a set of rotating shafts 15 and rotating guide plates 14 to rotate outward through two sets of flipping rods 16. During the rotation process, the rotating guide plates 14 are passively contracted because they are made of two sets of sliding plates. Therefore, there will be no interference. At this time, the upward flipping of the end of the guide plate 14 will cause the sliding frame 19 to move upward relative to the partition frame 2. As a result, the sliding frame 19 will drive the opening and closing plate 20 to open the connecting holes 18 on both sides of the partition frame 2, so that the connecting holes 18 change from the closed state to the open state. Thus, the internal spaces of the high-voltage chamber 4, the low-voltage chamber 5 and the transformer chamber 3 are interconnected. At this time, the suction force generated by the cooling fan 12 can also act on the high-voltage chamber 4 and the low-voltage chamber 5, so that the corresponding air inlet holes 8 of the high-voltage chamber 4 and the low-voltage chamber 5 can perform forced air intake operation. Similarly, the guide mechanism 6 installed inside the ventilation box door 7 can also ensure that the forced airflow can form a cooling airflow that runs from the bottom of the high-voltage cabinet and the low-voltage cabinet upward through the entire equipment, avoiding the problem of heat accumulation in the key heat-generating areas of the equipment and the inability to dissipate heat in time. As can be seen from the above, by adding a guide mechanism 6 to the lower inner side of the ventilation box door 7, it is possible to ensure that the forced-in cold air forms a heat dissipation airflow that runs from the bottom of the equipment upwards through the entire equipment, effectively improving the overall heat dissipation effect. At the same time, based on the temperature sensor installed inside and the data analysis, forced air intake can be carried out independently in the transformer room 3, high-voltage room 4 and low-voltage room 5, effectively reducing the energy consumption of the cooling fan 12 and achieving good results.
