Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a high-voltage SVG static reactive power compensation cabinet. Background Technology

[0002] SVG static reactive power compensation cabinet is a compensation device that uses SVG technology. It mainly consists of power electronic devices, control units, filters, etc. It can automatically adjust the reactive power output according to the real-time reactive power demand of the system, effectively solving reactive power problems in the power system, including voltage fluctuations, three-phase imbalance, low power factor, etc. With the widespread application of new energy and power electronic equipment, the load characteristics of the power system have changed. Traditional compensation devices can no longer meet the reactive power compensation needs of modern power systems. Due to its superior performance, SVG static reactive power compensation cabinet has become a better choice. Therefore, a high-voltage SVG static reactive power compensation cabinet is needed.

[0003] Currently used high-voltage SVG static compensation cabinets typically work by placing desiccant bags inside the mesh frame to absorb moisture after it enters the cabinet. However, this method makes it inconvenient to replace the desiccant bags, which become saturated after a period of use. New bags are then needed to maintain a dry environment inside the cabinet. If the bags are not replaced promptly, moisture will continue to accumulate inside the cabinet, leading to reduced dehumidification and potentially causing corrosion and malfunctions in the equipment. Long-term accumulation of moisture can also damage the electronic components inside the SVG, reducing its lifespan and potentially causing short circuits and other safety hazards. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-voltage SVG static reactive power compensation cabinet, which aims to improve the problem that it is inconvenient to replace the dehumidifying drying bag in the existing high-voltage SVG static reactive power compensation cabinet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage SVG static reactive power compensation cabinet, comprising a cabinet body, a fixed box fixedly connected to the bottom of the cabinet body, a placement box slidably connected inside the fixed box, guide rods fixedly connected to both sides of the inside of the fixed box, pull plates slidably connected to the outside of both guide rods, handles fixedly connected to the upper part of both pull plates, limit rods fixedly connected to the bottom of both pull plates, limit rods slidably connected to both sides of the inside of the placement box, return springs sleeved on the outside of both guide rods, pull plates fixedly connected to both ends of both return springs, and a handle fixedly connected to the front of the placement box.

[0008] Furthermore, both sides of the cabinet are fixedly connected to a mounting base, and each mounting base is fixedly connected to a sliding rod, with a compression spring sleeved on the outside of each sliding rod.

[0009] Furthermore, one end of each of the multiple compression springs is fixedly connected to the bottom of the slide plate, and the other end of each of the multiple compression springs is fixedly connected to a mounting base.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 3 , Figure 4 and Figure 6This utility model provides an embodiment of a high-voltage SVG static reactive power compensation cabinet, comprising a cabinet body 1. A fixed box 9 is fixedly connected to the bottom of the cabinet body 1. A placement box 10 is slidably connected inside the fixed box 9. Guide rods 14 are fixedly connected to both sides of the inside of the fixed box 9. Pull plates 12 are slidably connected to the outside of the two guide rods 14. Handles 13 are fixedly connected to the upper part of the two pull plates 12. Limiting rods 16 are fixedly connected to the bottom of the two pull plates 12. The two limiting rods 16 are slidably connected to the inside of the placement box 10. Return springs 15 are sleeved on the outside of the two guide rods 14. The two return springs 15 have two... Each end is fixedly connected to a pull plate 12, and the front of the placement box 10 is fixedly connected to a handle 11. The upper surface of the fixed box 9 is provided with through holes 20. The two sides inside the placement box 10 are provided with dehumidifying and drying bags 21. The two sides inside the placement box 10 are provided with grooves 19. Movable columns 17 are slidably connected inside the multiple grooves 19. One end of a compression spring 18 is fixedly connected to the side of the multiple movable columns 17 that is far apart from each other. The other end of the multiple compression springs 18 is fixedly connected inside the grooves 19. Limiting rods 16 are provided on the opposite side of the multiple movable columns 17. The two limiting rods 16 are slidably connected inside the fixed box 9.

[0026] With the help of the dehumidifying bag 21, the inside of the cabinet 1 is effectively dried and dehumidified. As the dehumidifying bag 21 is used for a longer period of time, maintenance becomes necessary. First, the operator gently pulls the two handles 13, driving the pull plate 12 to move smoothly along the outside of the guide rod 14. When the two guide rods 14 come together, they apply pressure to the return spring 15, causing it to undergo elastic deformation. Then, under the push of the return spring 15, the two pull plates 12 guide the limiting rod 16 to slowly move out of the placement box 10, thereby releasing the fixation on the placement box 10. Then, the operator only needs to simply pull the handle 1 1. The placement box 10 can be easily removed from the fixed box 9. After replacing the new desiccant bag 21, the operator puts the placement box 10 back into the fixed box 9. At this time, the handle 13 is released, and the pull plate 12 returns to its original position under the action of the return spring 15, guiding the limiting rod 16 to be reinserted into the placement box 10. During the insertion of the limiting rod 16, pressure is applied to the movable column 17, thereby compressing the second spring 18. As the limiting rod 16 is fully inserted, the multiple movable columns 17 move closer to each other under the elastic action of the compression spring 18, firmly locking the limiting rod 16 in position.

[0027] Reference Figure 1 , Figure 2 and Figure 5Electric push rods 3 are fixedly connected to both sides of the interior of cabinet 1. Baffles 4 are fixedly connected to the output ends of the two electric push rods 3. Limiting components are fixedly connected to both sides of the two baffles 4. The limiting components are used to limit the baffles 4. Dustproof plates 2 are fixedly connected to both sides of the interior of cabinet 1. The two baffles 4 are slidably connected to one side of the interior of the dustproof plate 2. The limiting components include sliding plates 5 and sliding rods 7. Multiple sliding plates 5 are fixedly connected to both sides of the two baffles 4. Multiple sliding plates 5 are slidably connected to the outside of the sliding rods 7. Fixed seats 6 are fixedly connected to both sides of the interior of cabinet 1. Sliding rods 7 are fixedly connected inside the multiple fixed seats 6. Compression springs 8 are sleeved on the outside of the multiple sliding rods 7. One end of the multiple compression springs 8 is fixedly connected to the bottom of the sliding plate 5. The other end of the multiple compression springs 8 is fixedly connected to the fixed seat 6.

[0028] The hot air inside the cabinet 1 is discharged to the outside through two high-efficiency dustproof plates 2, ensuring the efficiency and stability of the equipment's heat dissipation. However, in rainy weather, the system will automatically activate two electric push rods 3, whose output ends will precisely push the baffle 4 to move. During this process, the baffle 4 drives the slide plate 5 to slide along the outside of the slide rod 7. The downward movement of the slide plate 5 gradually compresses the spring 8 until the baffle 4 reaches the predetermined appropriate position, perfectly blocking the dustproof plate 2 and avoiding the risk of rainwater entering the cabinet 1.

[0029] Working Principle: During use, hot air inside the cabinet 1 is exhausted outward through two dustproof plates 2. In rainy weather, two electric push rods 3 are activated, pushing the baffle 4 to move. As the baffle 4 moves, the sliding plate 5 slides outside the sliding rod 7. When the sliding plate 5 slides downward, it compresses the compression spring 8, causing the baffle 4 to move to a suitable position and block the dustproof plate 2. This automatically blocks the dustproof plate 2, preventing rainwater from entering the cabinet 1 and ensuring long-term stable operation even in harsh environments, reducing the risk of equipment failure due to moisture. The dehumidifying bag 21 dries and dehumidifies the interior of the cabinet 1. After the dehumidifying bag 21 has been used for a period of time, the two handles 13 are pulled. The handles 13 cause the pull plate 12 to slide outside the guide rod 14. When the two guide rods 14 approach each other, they compress the return spring 15. The return spring 15 undergoes elastic deformation under compression. Under the action of the two pull plates 12, the two limit rods 16 are moved out of the inside of the placement box 10, releasing the fixation of the placement box 10. Next, by pulling the handle 11, the placement box 10 can be moved out of the inside of the fixed box 9. After the dehumidifying drying bag 21 is replaced, the placement box 10 is put into the inside of the fixed box 9. The two handles 13 are released, and under the action of the return spring 15, the two pull plates 12 move away from each other. The pull plates 12 drive the limit rods 16 to re-insert into the inside of the placement box 10. When the limit rods 16 are inserted into the inside of the placement box 10, they squeeze the movable column 17. The movable column 17 squeezes the compression spring 18. When the limit rods 16 are fully inserted, the multiple movable columns 17 move closer together under the elastic action of the compression spring 18, holding the limit rods 16 in place. This facilitates the replacement of the dehumidifying drying bag 21, allows for more frequent inspection and replacement, reduces the corrosion of internal components by moisture, and extends the service life of the equipment.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
