Description

Technical Field

[0001] This utility model relates to the technical field of low-voltage reactive power compensation cabinets, specifically to a low-voltage intelligent reactive power compensation control cabinet. Background Technology

[0002] In power systems, reactive power compensation technology is a key means to improve the power factor of the power grid, reduce line losses, and improve power supply efficiency. Low-voltage intelligent reactive power compensation control cabinets are reactive power compensation devices specifically designed for low-voltage power grids, primarily used to improve the efficiency and stability of the power system. They achieve reactive power adjustment through intelligent control and real-time monitoring, thereby optimizing the reactive power distribution of the power system, reducing energy loss, and improving power quality. However, common low-voltage intelligent reactive power compensation control cabinets generally suffer from a design flaw: heat-generating components such as reactors and capacitors are concentrated in the lower layer of the control cabinet. While this layout may improve efficiency to some extent... While simplifying the structural design of the control cabinet, it also brings significant heat dissipation problems. Reactors and capacitors, as the main heat-generating components, generate a lot of heat during long-term operation. When these heat-generating components are concentrated in the lower layer, the heat is difficult to dissipate effectively due to the limited space inside the control cabinet, causing the internal temperature of the control cabinet to rise continuously. This not only affects the performance and lifespan of the electrical components inside the control cabinet, but also increases the risk of equipment failure. Furthermore, the heat dissipation vents on the side of the cabinet lack corresponding protective structures, making it easy for external liquids to splash into the cabinet through the vents, thereby increasing the probability of failure of the internal components.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a low-voltage intelligent reactive power compensation control cabinet, including: a cabinet body 1, a main partition plate 4 fixedly connected to the upper end of the cabinet body 1, a secondary partition plate 12 fixedly connected to the lower end of the cabinet body 1, and a mounting plate 5 fixedly connected to the middle of the inner cavity of the cabinet body 1 by bolts. A temperature sensor 13 is fixedly connected to the lower surface of the mounting plate 5, and a guide plate 3 and an air guide cylinder 2 are fixedly connected to the upper surface of the main partition plate 4 respectively. Air outlets are opened on both sides of the cabinet body 1 relative to the positions of the air guide cylinder 2. Meanwhile, a diversion box 6 is fixedly connected to the upper surface of the secondary partition plate 12, and jet plates 7 are symmetrically connected to both sides of the diversion box 6. An air pump 8 is fixedly connected to the lower surface of the secondary partition plate 12, and the air outlet pipe of the air pump 8 is connected to the inner cavity of the diversion box 6. A mounting frame 11 is symmetrically connected to the lower surface of the secondary partition plate 12, and a filter plate 9 is fixedly connected inside the mounting frame 11. A flow baffle plate 10 is symmetrically connected to the bottom of the inner cavity of the cabinet body 1, and an air inlet is opened on the side of the cabinet body 1 relative to the position of the flow baffle plate 10.

[0018] In this embodiment, when the low-voltage intelligent reactive power compensation control cabinet is operating normally, heat will gradually accumulate inside the cabinet 1. The temperature sensor 13 can transmit the temperature data near the electrical components inside the cabinet 1 to the electrically connected PLC component in real time. Then, when the temperature data reaches the preset value range inside the PLC component, the PLC component will start the electrically connected air pump 8. The air pump 8 will draw airflow from the lower end of the inner cavity of the cabinet 1 and inject it into the distribution box 6. The external airflow will flow into the lower end of the inner cavity of the cabinet 1 through the air inlet opened at the lower end of the cabinet 1. When the external airflow flows to the air pump 8, it will pass through the filter plate 9, which is made of activated carbon. It can filter and dry the external airflow to ensure the cleanliness and dryness of the airflow output by the air pump 8. Then, part of the airflow inside the diversion box 6 flows out directly from the air outlet, and the other part of the airflow is ejected through the air outlet on the surface of the air jet plate 7, so that the airflow can flow evenly upward from the upper surface of the secondary partition plate 12. The airflow carrying heat will be guided by the inclined surface of the lower surface of the main partition plate 4 to flow from the air guide tube 2 into the upper end of the inner cavity of the cabinet 1, and then discharged from the air outlet at the upper end of the inner cavity of the cabinet 1. This effectively enhances the heat dissipation effect inside the control cabinet, reduces the probability of heat residue accumulation, and ensures that the temperature inside the cabinet 1 is within a suitable range.

[0019] In a preferred embodiment, the main partition plate 4 is generally square in shape, the through-hole in the middle of the main partition plate 4 is square in shape, the lower surface of the main partition plate 4 is frustum-shaped, and the air guide tube 2 fixedly connected to the middle of the upper surface of the main partition plate 4 is cylindrical in shape, and the air guide tube 2 is connected to the through-hole.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The sloping structure on the lower surface of the main partition plate 4 can help guide the flow of air, allowing the air to carry heat away from the middle of the inner cavity of the cabinet 1 quickly, thereby improving the heat dissipation effect inside the control cabinet.

[0021] In a preferred embodiment, two sets of guide plates 3 are fixedly connected to the upper surface of the main partition plate 4. Both sets of guide plates 3 have a concave structure, and the groove size of the guide plate 3 is compatible with the size of the outer side of the air guide cylinder 2. At the same time, the end face of the guide plate 3 has a right-angled triangular structure, and the side of the upper surface of the guide plate 3 near the air outlet is inclined downward.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3The structure of the guide plate 3 can work with the air guide tube 2 to intercept external liquids that accidentally flow in from the air outlet. Furthermore, the inclined structure of the guide plate 3 can guide the liquid to flow out quickly, thereby reducing the probability of external liquids flowing into the middle of the inner cavity of the cabinet 1 and ensuring the safety of the electrical components inside the control cabinet.

[0023] In a preferred embodiment, the sub-partition plate 12 has a square structure, and the diversion box 6 fixedly connected to the upper surface of the sub-partition plate 12 has a cuboid structure, and multiple sets of air outlet holes are evenly opened on the upper surface of the diversion box 6.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The design of the diversion box 6 simplifies the pipe layout between the air pump 8 and the jet plate 7, and the opening of the air outlet helps to improve the uniformity of airflow in the middle of the cabinet 1 cavity.

[0025] In a preferred embodiment, multiple sets of jet plates 7 are fixedly connected to both sides of the diversion box 6 at equal intervals along the length direction. The cross-section of the jet plate 7 is U-shaped, and multiple sets of jet holes are evenly opened on the upper surface of the jet plate 7. At the same time, the jet plate 7 and the diversion box 6 are combined to form a Feng-shaped structure.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The inner cavity of the diversion box 6 is connected to the inner cavity of the jet plate 7, so that the airflow in the diversion box 6 can flow into the inner cavity of the jet plate 7, and then be evenly sprayed out from the jet holes opened on the surface of the jet plate 7, ensuring that the airflow can flow evenly from the lower end to the upper end of the inner cavity of the cabinet 1, thereby enhancing the heat dissipation effect inside the control cabinet.

[0027] As a preferred embodiment, there are two sets of mounting frames 11. Both sets of mounting frames 11 are U-shaped structures. The upper surface of the mounting frame 11 is fixedly connected to the lower surface of the sub-partition plate 12, and the lower surface of the mounting frame 11 is fixedly connected to the bottom of the inner cavity of the cabinet 1. At the same time, the inner side of the mounting frame 11 is provided with a mounting groove, and the filter plate 9 is fixedly connected in the mounting groove by a buckle. The filter plate 9 is square in structure.

[0028] In this embodiment, as Figure 1 and Figure 4 The installation frame 11 improves the ease of installing and removing the filter plate 9. Moreover, the filter plate 9 is made of activated carbon, which can filter and dry the flowing gas, thereby reducing the humidity in the middle of the cabinet 1 cavity and reducing the probability of electrical component failure in the cabinet 1.

[0029] As a preferred embodiment, two sets of baffles 10 are fixedly connected to both ends of the bottom of the inner cavity of the cabinet 1. Both sets of baffles 10 are hollow right-angled triangular prism structures, and the inclined surface of the baffles 10 faces the air inlet of the cabinet 1. At the same time, the filter screen is fixedly connected to the outer side of the cabinet 1 relative to the positions of the air inlet and the air outlet by snap-fit.

[0030] In this embodiment, as Figure 1 and Figure 4 The baffle plate 10 can effectively intercept external liquids that accidentally flow in from the air inlet, reducing the chance of external liquids flowing into the cabinet 1. At the same time, the filter screen can intercept and filter dust in the airflow, improving the cleanliness of the cabinet 1. The hollow structure of the baffle plate 10 can reduce the amount of material used.

[0031] The low-voltage intelligent reactive power compensation control cabinet of this utility model, through the cooperation of the baffle plate 10, filter plate 9, air pump 8, diverter box 6 and jet plate 7, can not only enhance the airflow speed inside the control cabinet and improve the heat dissipation effect inside the control cabinet, but also help filter and dry the incoming external airflow, reducing the probability of accidental damage to the electrical components inside the control cabinet. At the same time, the PLC component fixedly connected to the bottom of the inner cavity of the cabinet 1 and the intelligent control component set inside the cabinet 1 can both adopt common brands and models on the market.
