Description

Technical Field

[0001] This utility model relates to the field of compensation cabinet technology, specifically to a low-voltage dynamic compensation cabinet. Background Technology

[0002] Low-voltage dynamic compensation cabinets are electrical devices used in low-voltage power distribution systems. They achieve dynamic reactive power compensation through real-time monitoring and rapid switching of capacitor banks, thereby improving power quality and grid operating efficiency. They are widely used in places such as shopping malls, hotels, and office buildings for reactive power compensation of equipment such as air conditioners, elevators, and lighting, thereby improving power utilization and reducing electricity costs.

[0003] In current low-voltage dynamic compensation cabinets, in order to facilitate heat dissipation, heat dissipation holes are often opened on the side wall or top of the cabinet body to carry away heat through natural air convection. However, the heat dissipation effect is limited, the heat dissipation is slow, and it is difficult to cope with the heat generated by the large number of heat-generating components inside the compensation cabinet. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A low-voltage dynamic compensation cabinet, comprising:

[0006] The cabinet has a door rotatably connected to the front side, exhaust vents are provided on both the left and right sides near the top, air inlets are provided on both the left and right sides near the bottom, exhaust fans are connected to both sides of the cabinet near the exhaust vents, and air inlets are connected to both sides of the cabinet near the air inlets.

[0007] Both sides of the cabinet are connected to air guide hoods near the air inlets. Five frames are connected from top to bottom on the front side of the air guide hoods. Side panels are connected to both sides of the frames. Air guide nozzles are rotatably connected inside the side panels.

[0008] The left-side panel has a positioning mechanism inside.

[0009] In one possible implementation, a bearing is embedded inside the side plate, and a shaft is rotatably connected inside the bearing. One end of the shaft is fixedly connected to the air guide nozzle, and the other end of the shaft is connected to a knob.

[0010] In one possible implementation, the positioning mechanism includes a rod, one end of which passes through the interior of the knob and the side plate in sequence.

[0011] In one possible implementation, the left side plate has five first positioning holes circumferentially arranged inside, and the knob has a second positioning hole located near the first positioning holes inside. One end of the insert rod passes through the interior of the second positioning hole and the first positioning hole in sequence.

[0012] In one possible implementation, the five first positioning holes are arranged in a semi-circular pattern with the bearing as the center.

[0013] In one possible implementation, a sealing sheet is connected to the back side of the air guide nozzle, and the outer side of the sealing sheet is fixedly connected to the inner wall of the frame.

[0014] In one possible implementation, the air guide is configured in an L-shape.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By opening air inlets on both sides of the bottom of the cabinet and exhaust vents on both sides of the top, and simultaneously activating a pair of exhaust fans and a pair of intake fans at the top and bottom, the intake and exhaust fans significantly improve the airflow speed and volume through forced airflow, allowing hot air inside the compensation cabinet to be expelled more quickly while introducing external cold air, thus removing heat more efficiently. In addition, air guide hoods and five rotatable air nozzles are installed on both sides of the cabinet, which helps to evenly distribute external cold air to the components on both the upper and lower layers, ensuring that all components on both the upper and lower layers receive good heat dissipation, further improving the heat dissipation effect. This solves the problem that relying on natural air convection to remove heat has limited heat dissipation effect and slow heat dissipation, making it difficult to cope with the heat generated by a large number of heat-generating components inside the compensation cabinet.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This application provides a low-pressure dynamic compensation cabinet to solve the problems in the prior art.

[0027] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0028] like Figures 1-5 As shown, a low-voltage dynamic compensation cabinet includes:

[0029] Cabinet 1 has a cabinet door 4 that is rotatably connected to the front side of the cabinet 1. Exhaust vents 7 are provided on both the left and right sides near the top of the cabinet 1, and air inlets 8 are provided on both the left and right sides near the bottom of the cabinet 1. Exhaust fans 5 are connected to both sides of the cabinet 1 near the exhaust vents 7, and air inlets 6 are connected to both sides of the cabinet 1 near the air inlets 8. The air inlets 5 and exhaust fans 6 drive the air to flow in a forced manner, which can significantly improve the air circulation speed and flow rate, allowing the hot air inside the cabinet to be expelled more quickly, while introducing cold air from outside, thereby removing heat more efficiently.

[0030] Air guide hoods 2 are connected to both sides of the cabinet 1 near the air inlet 8. Five frames 9 are connected from top to bottom on the front side of the air guide hood 2. Side panels 17 are connected to both sides of the frame 9. Air guide nozzles 3 are rotatably connected inside the side panels 17, which helps to distribute the external cold air evenly to the upper and lower layers of components, ensuring that the upper and lower layers of components can get good heat dissipation, and further improving the heat dissipation effect.

[0031] A positioning mechanism is provided inside the left side panel 17.

[0032] In some examples, a bearing 10 is embedded inside the side plate 17, and a shaft 16 is rotatably connected inside the bearing 10. One end of the shaft 16 is fixedly connected to the air guide nozzle 3, and the other end of the shaft 16 is connected to a knob 12. The connection between the bearing 10 and the shaft 16 allows the air guide nozzle 3 to rotate flexibly.

[0033] In some examples, the positioning mechanism includes a rod 14, one end of which passes through the inside of the knob 12 and the side plate 17 in sequence. When it is necessary to adjust the angle of the air guide nozzle 3, one end of the rod 14 is first taken out from the inside of the second positioning hole 13 and the first positioning hole 11, which makes it convenient to rotate the air guide nozzle 3.

[0034] In some examples, the left side panel 17 has five first positioning holes 11 circumferentially arranged inside, and the knob 12 has a second positioning hole 13 located near the first positioning hole 11 inside. One end of the insert rod 14 passes through the interior of the second positioning hole 13 and the first positioning hole 11 in sequence. When one end of the insert rod 14 is inserted into the interior of the second positioning hole 13 and the first positioning hole 11, it is convenient to position the air guide nozzle 3. Similarly, when it is necessary to adjust the angle of the air guide nozzle 3, one end of the insert rod 14 is first taken out from the interior of the second positioning hole 13 and the first positioning hole 11, and the angle of the air guide nozzle 3 can be easily rotated.

[0035] In some examples, the five first positioning holes 11 are distributed in a semi-circular shape with the bearing 10 as the center, which is beneficial for limiting the rotation angle of the air guide nozzle 3.

[0036] In some examples, a sealing strip 15 is connected to the back side of the air guide nozzle 3. The outer side of the sealing strip 15 is fixedly connected to the inner wall of the frame 9. By setting the sealing strip 15, it is beneficial to seal the area between the air guide nozzle 3 and the frame 9 to prevent air leakage.

[0037] In some examples, the air deflector 2 is set to an L-shape.

[0038] This invention features air inlets 8 on both sides of the bottom of the cabinet 1 and exhaust vents 7 on both sides of the top. Simultaneously, a pair of exhaust fans 5 and a pair of intake fans 6 are activated at the top and bottom. The intake and exhaust fans 5 and 6 forcefully drive airflow, significantly increasing air circulation speed and flow rate, allowing hot air inside the cabinet to be expelled more quickly while introducing external cold air, thus more efficiently removing heat. Furthermore, air guide hoods 2 and five rotatable air nozzles 3 are installed on the side walls of the cabinet 1, facilitating the even distribution of external cold air to the upper and lower components, ensuring good heat dissipation for all components and further improving the heat dissipation effect.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
