Description

Technical Field

[0001] This utility model relates to the field of static var generator technology, and in particular to a novel static var generator. Background Technology

[0002] A Static Var Generator (SVG) is a power electronic device used in power systems. Its main function is to provide or absorb reactive power, thereby maintaining the voltage stability of the power grid and improving power quality. SVG responds to system load changes by rapidly adjusting reactive power, effectively compensating for reactive power demand in the power system and reducing voltage fluctuations and harmonic interference. Compared with traditional reactive power compensation devices, SVG has advantages such as fast response speed, high adjustment accuracy, and small size, and is widely used in wind power, photovoltaic power generation, and industrial power applications.

[0003] In some large-scale circuit systems, multiple static var generators are often integrated into the same control cabinet to form a large static var generator, which facilitates unified control. When it is running, the internal electronic components generate a lot of heat, which needs to be dissipated through the combination of heat dissipation holes and fans to reduce the operating temperature and ensure the stable operation of the equipment.

[0004] However, the concentration of multiple static var generators results in a high load on the entire device during operation, leading to a significant amount of heat generation. The combination of heat dissipation holes and fans alone is insufficient to quickly dissipate the heat from inside the device, causing the internal temperature to rise continuously and affecting the device's performance and lifespan. Furthermore, the dust filters at the through-holes are prone to clogging with dust during continuous heat dissipation, resulting in poor heat dissipation. Therefore, those skilled in the art propose a novel static var generator to address the aforementioned problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel static var generator, which aims to improve the problem that large static var generators in the prior art cannot quickly dissipate the heat inside the equipment in a timely manner, thus causing the internal temperature of the equipment to rise continuously, affecting the performance and lifespan of the equipment. At the same time, the dust filter is easily blocked by dust, resulting in poor heat dissipation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel static var generator includes a cabinet, a liquid storage tank fixedly connected to the bottom of the cabinet, a circulation pump fixedly connected to the outside of the liquid storage tank, a cooler fixedly connected to the output end of the circulation pump, a cooling pipe fixedly connected to the outside of the cooler, one end of the cooling pipe fixedly connected to the outside of the liquid storage tank, a horizontal plate fixedly connected to the upper part of the cabinet near the cooling pipe, a fan mounted on the horizontal plate, a dustproof net installed at the through hole on the rear side of the cabinet, a dust removal component provided on the rear side of the cabinet for cleaning dust from the surface of the dustproof net, and a mounting frame fixedly connected to the inside of the cabinet, on which multiple var generator bodies are mounted by snap-fit ​​components;

[0007] The dust removal component includes two fixed blocks, both of which are fixedly connected to the inner wall of the cabinet. A movable rod is slidably connected inside the fixed blocks. A movable frame is fixedly connected to the adjacent ends of the two movable rods. A rack plate is fixedly connected to the upper and lower sides of the inner side of the movable frame. A brush is fixedly connected to the upper and lower sides of the outer side of the movable frame. A drive component is provided on the rear side of the cabinet, and the drive component moves the movable frame by driving it.

[0008] Furthermore, the drive assembly includes a motor, which is mounted on the rear side of the cabinet. The output end of the motor extends into the interior of the cabinet and is fixedly connected to a sector gear. The exterior of the sector gear meshes with a rack plate.

[0009] Furthermore, the snap-fit ​​assembly includes a limiting block, which is slidably connected to a limiting groove opened inside the mounting bracket. A pull rod is fixedly connected to one side of the limiting block, and a spring is sleeved on the outside of the pull rod. A locking block is fixedly connected to the other side of the limiting block, and a locking groove is opened on the side of the reactive power generator body.

[0010] Furthermore, each cabinet has a door rotatably connected to its front side, and an injection pipe is fixedly connected to the outside of the liquid storage tank, extending to the outside of the cabinet.

[0011] Furthermore, the circulating pump is fixedly connected to the inner bottom of the cabinet, and the cooling pipe is serpentine in shape.

[0012] Furthermore, the surface of the brush is in contact with the surface of the dustproof net.

[0013] Furthermore, one end of the spring is fixedly connected to the inner wall of the limiting groove, and the other end of the spring is fixedly connected to one side of the limiting block.

[0014] Furthermore, the outside of the card block engages with the inside of the card slot.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the operation of the circulating pump causes the coolant to circulate in the cooling pipes, reducing the temperature of the surrounding air during the flow. Then, the cool air is blown into the interior of the upper cabinet by the fan, thereby cooling the multiple reactive power generator bodies on the mounting frame. This solves the problems of poor heat dissipation and slow cooling rate of traditional heat dissipation methods, preventing damage to internal components at high temperatures during equipment operation and affecting normal operation. At the same time, the motor drives the sector gear to rotate, which in turn causes the moving frame to move the brush left and right continuously, cleaning the surface of the dustproof net. This prevents dust and impurities in the air from adhering to the dustproof net during airflow, causing blockage and affecting the internal air circulation, thus further improving the heat dissipation effect.

[0017] 2. In this utility model, the reactive power generator body presses the two side blocks to move inward toward the limiting groove, and then the spring pushes the blocks into the groove, thus fixing the reactive power generator body. This reduces the need for cumbersome fixing methods such as screws during installation and improves installation efficiency. At the same time, by pulling the pull rod, the limiting block slides inside the limiting groove, and then the limiting block causes the blocks to disengage from the groove, thereby enabling quick disassembly of the reactive power generator body, which is convenient for inspection and maintenance.

[0026] 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.

[0027] Reference Figure 1 - Figure 4This utility model provides an embodiment of a novel static var generator, comprising a cabinet 1. The cabinet 1 has a rotatable door 11 on its front side, allowing easy opening of the cabinet 1 for maintenance of the internal var generator body 13. A liquid storage tank 2 is fixedly connected to the inner bottom of the cabinet 1, primarily storing coolant for heat dissipation, ensuring a sufficient supply of coolant during the heat dissipation process. A circulation pump 3 is fixedly connected to the outside of the liquid storage tank 2, enabling coolant circulation and reducing coolant usage costs. A cooler 4 is fixedly connected to the output end of the circulation pump 3. The cooler 4 is a prior art technology that can rapidly cool the coolant as it passes through, thereby improving heat dissipation. A cooling pipe 5 is fixedly connected to the outside of the cooler 4, with one end of the cooling pipe 5 fixedly connected to the outside of the liquid storage tank 2. The circulation pump 3 is fixedly connected to the inner bottom of the cabinet 1. The cooling pipe 5 has a serpentine shape; this serpentine design increases the heat dissipation area of ​​the cooling pipe 5, allowing it to fully contact the surrounding air, thus facilitating the cooling of the coolant. The heat exchange between the air and the liquid tank is more complete and efficient, and the temperature of the surrounding air is reduced quickly. The liquid tank 2 is fixedly connected to the outside of the liquid injection pipe 10, and the liquid injection pipe 10 extends to the outside of the cabinet 1. Its function is to facilitate the addition of coolant to the liquid tank 2 when the coolant in the heat dissipation system is insufficient, so as to ensure the stable operation of the heat dissipation system. The inside of the cabinet 1 is fixedly connected to the upper part of the cooling pipe 5. The fan 7 is installed on the horizontal plate 6. The horizontal plate 6 provides a mounting platform for the fan 7 so that it can operate stably. The dustproof net 8 is installed at the through hole on the rear side of the cabinet 1. Its main function is to prevent dust and impurities in the outside air from entering the inside of the cabinet 1 and causing pollution and damage to the equipment. It also avoids the accumulation of too much dust inside the equipment, which affects the heat dissipation effect and normal operation of the equipment. The dust removal component is set on the rear side of the inside of the cabinet 1. The dust removal component is used to clean the dust on the surface of the dustproof net 8. The mounting bracket 12 is fixedly connected to the inside of the cabinet 1. Multiple reactive power generator bodies 13 are installed on the mounting bracket 12 through the snap-fit ​​component.

[0028] Reference Figure 2 and Figure 5The dust removal component includes two fixed blocks 15, both of which are fixedly connected to the inner wall of the cabinet 1. A movable rod 16 is slidably connected inside each fixed block 15, providing a guide rail and support for the sliding of the movable rod 16. A movable frame 17 is fixedly connected to the adjacent ends of the two movable rods 16. A rack plate 18 is fixedly connected to the upper and lower inner sides of the movable frame 17, and brushes 25 are fixedly connected to the upper and lower outer sides of the movable frame 17. A drive assembly is located at the rear of the cabinet 1, driving the movable frame 17 to move. Driven by the moving component, the moving frame 17 moves left and right, which can drive the brush 25 to clean the surface of the dustproof net 8, ensuring smooth air circulation inside and further improving the heat dissipation effect of the heat dissipation system. The driving component includes a motor 9, which is installed on the rear side of the cabinet 1. The output end of the motor 9 extends into the interior of the cabinet 1 and is fixedly connected to a sector gear 14. The motor 9, as the driving source, can drive the sector gear 14 to rotate. The outside of the sector gear 14 is meshed with the rack plate 18, and the surface of the brush 25 is in contact with the surface of the dustproof net 8.

[0029] Specifically, when the equipment is dissipating heat, the reactive power generator body 13 can be started first. The circulating pump 3 draws coolant from the storage tank 2 and delivers it to the cooler 4. The cooler 4 can quickly cool the coolant as it passes through. The coolant then flows into the cooling pipe 5 and finally returns to the storage tank 2, achieving a circulating cooling effect. When the coolant flows inside the cooling pipe 5, it undergoes rapid heat exchange with the air, thereby reducing the temperature of the surrounding air. Then, the fan 7 blows this cool air into the interior of the upper cabinet 1, cooling the multiple reactive power generator bodies 13 mounted on the mounting bracket 12, thus solving the problem of traditional heat dissipation. To address the issues of poor heat dissipation and slow cooling rate of thermal methods, this system prevents internal components from being damaged at high temperatures during operation, thus affecting the normal operation of the equipment. Simultaneously, during cooling, motor 9 can be activated, driving the sector gear 14 to rotate. The sector gear 14 meshes with the rack plates 18 on the upper and lower sides, allowing the moving frame 17 to move continuously left and right under the support and constraint of the fixed block 15 and the moving rod 16. This, in turn, drives the brush 25 to clean the surface of the dustproof net 8, preventing dust and impurities in the air from adhering to the dustproof net 8 and causing blockage, thus further improving the heat dissipation effect.

[0030] Reference Figure 6The snap-fit ​​assembly includes a limiting block 22, which is slidably connected to a limiting groove 19 inside the mounting bracket 12. The limiting groove 19 restricts the movement of the limiting block 22. A pull rod 21 is fixedly connected to one side of the limiting block 22, which facilitates pulling the limiting block 22 to move inside the limiting groove 19 to achieve disassembly. A spring 20 is sleeved on the outside of the pull rod 21. A locking block 23 is fixedly connected to the other side of the limiting block 22. A locking groove 24 is opened on the side of the reactive power generator body 13. One end of the spring 20 is fixedly connected to the inner wall of the limiting groove 19, and the other end of the spring 20 is fixedly connected to one side of the limiting block 22. The outside of the locking block 23 engages with the inside of the locking groove 24. The spring 20 can push the locking block 23 to reset and complete the automatic fixing process without additional manual operation.

[0031] Specifically, when installing the reactive power generator body 13, it is placed on the partition of the mounting bracket 12 and pushed into the mounting bracket 12. This compresses the locking blocks 23 on both sides, causing them to move inward toward the limiting groove 19. At the same time, the spring 20 is compressed and retracted. When the locking blocks 23 are aligned with the locking grooves 24 on both sides of the reactive power generator body 13, the spring 20 will rebound and push the locking blocks 23 back to their original position, thus locking them into the locking grooves 24. This fixes the reactive power generator body 13, reducing the need for cumbersome fixing methods such as screws during installation and improving installation efficiency. Simultaneously, by pulling the pull rod 21, the limiting block 22 slides inside the limiting groove 19, thereby causing the locking blocks 23 to disengage from the locking grooves 24. This allows for quick disassembly of the reactive power generator body 13, facilitating its inspection and maintenance.

[0032] Working principle: When cooling the equipment, the circulating pump 3 draws coolant from the storage tank 2 and delivers it to the cooler 4. After being cooled by the cooler 4, it is delivered to the cooling pipe 5. As the coolant flows inside the cooling pipe 5, it dissipates heat and emits cold air. At this time, the fan 7 blows this cold air into the interior of the upper cabinet 1, thereby cooling the multiple reactive power generator bodies 13 mounted on the mounting bracket 12. This solves the problems of poor heat dissipation and slow cooling rate of traditional heat dissipation methods. During cooling, the motor 9 can be started, which drives the sector gear 14 to rotate. Under the meshing of the sector gear 14 and the rack plate 18, the moving frame 17 can move left and right continuously, thereby driving the brush 25 to clean the surface of the dustproof net 8 and avoid... To prevent dust and impurities in the air from adhering to the dustproof mesh 8 during airflow, which could cause blockage and affect internal air circulation, thus improving heat dissipation, the following steps are taken: First, when installing the reactive power generator body 13 on the mounting bracket 12, pulling the lever 21 causes the limiting block 22 to slide inside the limiting groove 19. This, in turn, causes the locking block 23 to move inwards towards the limiting groove 19. At this point, the reactive power generator body 13 can be placed on the partition of the mounting bracket 12. Then, releasing the lever 21 allows the spring 20 to push the limiting block 22 back to its original position, allowing the locking block 23 to be inserted into the locking slot 24, thus securing the reactive power generator body 13. This reduces the use of screws during installation and improves installation efficiency.

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.
