Description

Technical Field

[0001] This invention relates to the field of power supply equipment, specifically to an outdoor filter compensation cabinet. Background Technology

[0002] With the rapid development of science and technology in my country, a large number of power electronic devices have been put into widespread use in the power grid, making the problems of dynamic reactive power compensation and harmonic control increasingly prominent. Harmonics often appear in the power distribution system. These harmonics not only pollute the power grid but also threaten the normal operation of equipment and reduce the utilization rate of equipment. Therefore, filtering compensation is carried out.

[0003] For example, CN209419228U discloses an outdoor filter compensation cabinet, which includes a cabinet body. The cabinet body includes an outer cabinet and an inner cabinet disposed inside the outer cabinet. A pad is provided between the bottom of the inner cabinet and the outer cabinet. A heat-conducting plate is provided inside the inner cabinet and is fixedly attached to the inner surface of the back panel of the inner cabinet. The upper end of the heat-conducting plate extends to the top of the outer cabinet. A water tank is provided above the outer cabinet, and water is provided in the water tank. The surface of the portion of the heat-conducting plate located in the water tank is provided with finned plates. Multiple finned plates are provided on both sides of the heat-conducting plate and are arranged perpendicular to the heat-conducting plate. This outdoor filter compensation cabinet has a double-layer cabinet design, which is effective in preventing rain and dust, is suitable for outdoor use, and has good heat dissipation inside the inner cabinet. It is worth promoting.

[0004] While the compensation cabinet described above is suitable for outdoor use and rainproof, high humidity levels in the surrounding environment during rainfall can negatively impact the electrical components inside the cabinet. This moisture can easily cause the components to become damp, reducing their lifespan and stability. Furthermore, existing outdoor filter compensation cabinets typically rely on natural ventilation or simple air-cooling structures for heat dissipation. These methods may not meet the heat dissipation requirements of the electrical components in high-temperature environments, thus affecting the overall performance of the equipment. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figure 1 , Figure 2 and Figure 4 The outdoor filter compensation cabinet shown in the figure includes: a cabinet body 1, with an inlet door 2 and an outlet door 3 rotatably installed on the upper and lower ends of the front side of the cabinet body 1, and two mounting columns 4 symmetrically fixed on the inner wall of the cabinet body 1, with multiple mounting beams 5 evenly distributed between the two mounting columns 4 for fixing electrical components. It also includes: a support plate 6 fixed to the bottom of the mounting column 4, the support plate 6 having a mounting hole 7, and an adsorption unit 8 installed in the mounting hole 7 for absorbing and treating the moisture entering the cabinet 1 from the outside, thereby preventing electrical components from being damaged by the humid environment and extending the service life of the equipment. The liquid cooling unit 9 is located between the mounting beam 5 and the adsorption unit 8. The liquid cooling unit 9 is used to further absorb the heat generated by the electrical components inside the cabinet 1 during operation, further improving the heat dissipation efficiency of the compensation cabinet and ensuring that the electrical components are always at a suitable working temperature, thereby ensuring the stable operation of the equipment. The polarization unit 10 is fixed at the bottom of the adsorption unit 8. The polarization unit 10 is used to enhance the adsorption capacity of the adsorption unit 8, so that the adsorption effect of the adsorption unit 8 can be greatly improved in a humid environment.

[0021] For further details, please refer to [link / reference]. Figures 2-4The adsorption unit 8 includes an annular plate 11 fixed to the support plate 6 by bolts. A hollow cylindrical shell 12 is fixed to the bottom of the annular plate 11. The upper and lower ends of the hollow cylindrical shell 12 are provided with circular holes, and a slewing bearing 13 is snapped into the circular holes. An annular connecting sleeve 14 is rotatably connected to the inner side of the slewing bearing 13. A moisture-absorbing bladder 15 is fixed between the two annular connecting sleeves 14 distributed vertically. A permanent electric iron core 16 is fixedly sleeved in the middle of the moisture-absorbing bladder 15. A rotating shaft 17 is fixedly sleeved in the middle of the permanent electric iron core 16. A drive assembly 18 is drivenly connected to the top end of the rotating shaft 17, and an air intake fan 19 is fixedly sleeved at its bottom end. The polarization unit 10 is fixed to the bottom of the hollow cylindrical shell 12. Among them, see Figure 5 and Figure 8 The drive assembly 18 includes a speed-regulating motor 20 fixedly installed at the bottom of the support plate 6. The output end of the speed-regulating motor 20 is fixed with a drive pulley 21, and the top end of the rotating shaft 17 is fixed with a driven pulley 22. A belt 23 is connected between the drive pulley 21 and the driven pulley 22. A humidity sensor 30 is fixed on the bottom inner wall of the cabinet 1, and the humidity sensor 30 is electrically connected to the speed-regulating motor 20.

[0022] Specifically, the humidity sensor 30 can monitor the humidity inside the cabinet 1 in real time. When the humidity exceeds the set value, the speed-regulating motor 20 will be activated. The speed-regulating motor 20 drives the active pulley 21 to rotate, which in turn drives the driven pulley 22 to rotate via the belt 23. The driven pulley 22 drives the rotating shaft 17 to rotate, which in turn drives the permanent electric iron core 16 to rotate. At the same time, the moisture-absorbing bag 15 and the air intake fan 19 rotate together. The air intake fan 19 generates negative pressure at the bottom of the cabinet 1, which re-inhales the humid air outside the cabinet 1 into the cabinet 1. Since the moisture-absorbing bag 15 has honeycomb-shaped moisture-absorbing channels evenly distributed inside, the adsorption efficiency is extremely high. In addition, the permanent electric iron core 16 emits charges on its surface, which allows water vapor and dust and other impurities in the inhaled moisture to be adsorbed by electrostatics, further enhancing the adsorption effect of the moisture-absorbing bag 15.

[0023] It should be noted that the bottom of the hollow cylindrical shell 12 is provided with a connection hole, and a drain pipe 28 is sealed and inserted into the connection hole. The end of the drain pipe 28 away from the hollow cylindrical shell 12 passes through the inner and outer walls of the cabinet 1 and extends out of the cabinet 1. When enough water vapor is absorbed into the moisture absorption channel of the moisture absorption bladder 15, it will condense into small water droplets. These small water droplets are thrown to the inner wall of the hollow cylindrical shell 12 by the centrifugal force generated by the rotation of the moisture absorption bladder 15. They accumulate and form a water flow, which is slowly discharged from the cabinet 1 through the drain pipe 28.

[0024] In addition, after the moisture-absorbing bladder 15 absorbs dust and other impurities in the air, these impurities will combine with the small water droplets formed by the condensation of water vapor. The rotating moisture-absorbing bladder 15 will further filter and shake out the dust and other impurities in the moisture, thus preventing the moisture-absorbing bladder 15 from absorbing too much impurities and becoming clogged, which would affect the performance.

[0025] For further details, please refer to [link / reference]. Figure 6 The bottom of the cabinet 1 is evenly distributed with air inlet slots 29, which are connected to the bottom space of the cabinet 1. The design of the air inlet slots 29 can ensure that external air can smoothly enter the interior of the cabinet 1. At the same time, the operation of the air intake fan 19 forms a directional airflow to ensure that the moisture is effectively guided to the vicinity of the moisture-absorbing bag 15 for treatment.

[0026] For further details, please refer to [link / reference]. Figure 6 and Figure 9 The cabinet 1 has evenly distributed exhaust vents 31 on its top front side, and a rain shield 32 is fixed to the outside of each exhaust vent 31. The exhaust vents 31 are designed to expel the treated air from inside the cabinet 1, while the rain shield 32 effectively prevents rainwater from entering the cabinet 1 through the exhaust vents 31, ensuring the safety and stability of the equipment in outdoor environments. In addition, the exhaust vents 31 at the top of the cabinet 1 and the air inlet 29 at the bottom form a convection structure, further improving air circulation efficiency, allowing moisture to be captured and processed by the adsorption unit 8 more quickly, thereby maintaining a dry working environment inside the cabinet 1.

[0027] Example 2 Please see Figure 4 and Figure 7 This embodiment further illustrates Example 1, with the difference being the optimization of the adsorption effect of adsorption unit 8.

[0028] Specifically, the adsorption unit 8 includes an annular plate 11 fixed to the support plate 6 by bolts. A hollow cylindrical shell 12 is fixed to the bottom of the annular plate 11. Circular holes are provided at both the upper and lower ends of the hollow cylindrical shell 12, and a slewing bearing 13 is engaged within each hole. An annular connecting sleeve 14 is rotatably connected to the inner side of the slewing bearing 13. A moisture-absorbing bladder 15 is fixed between two vertically distributed annular connecting sleeves 14. A permanent electric iron core 16 is fixedly sleeved in the middle of the moisture-absorbing bladder 15. A rotating shaft 17 is fixedly sleeved in the middle of the core 16. A drive assembly 18 is connected to the top of the rotating shaft 17, and an air intake fan 19 is fixedly sleeved at its bottom. The polarization unit 10 is fixed to the bottom of the hollow shell 12. The polarization unit 10 includes an annular plate 24 fixed to the bottom of the hollow shell 12. The annular plate 24 and the rotating shaft 17 are coaxially distributed. A conductive plate 25 is fixed to the bottom of the annular plate 24, and the air intake fan 19 is located inside the conductive plate 25.

[0029] Specifically, when the rainfall and humidity are both high, the conductive plate 25 will be energized and the speed-regulating motor 20 will speed up. After being energized, the conductive plate 25 will dissipate charges along the path of the gas, pre-charge the water vapor and dust impurities in the gas, and combine them with the charges on the permanent electric iron core 16, which can enhance the adsorption capacity of the moisture-absorbing bag 15, thereby significantly improving the working efficiency of the adsorption unit 8 in high humidity environments.

[0030] Example 3 Please see Figure 5 This embodiment further illustrates Example 1, with the difference being the optimization of the heat dissipation method of the cabinet 1.

[0031] Specifically, the liquid cooling unit 9 includes a heat dissipation coil 26 spirally arranged around the outside of the moisture-absorbing bladder 15. The first and last ends of the heat dissipation coil 26 are fixedly connected to a serpentine tube 27. Both ends of the serpentine tube 27 are connected through the hollow shell 12. The portion of the serpentine tube 27 located outside the hollow shell 12 is distributed on the rear side of the mounting beam 5.

[0032] It should be noted that the coolant filling the heat dissipation coil 26 and the serpentine tube 27 can indirectly contact the hot airflow generated by the electrical components inside the cabinet 1 during operation, thereby dissipating heat from the cabinet 1. When the coolant inside the heat dissipation coil 26 and the serpentine tube 27 absorbs a large amount of heat, it will turn into a gaseous state. Since the heat dissipation coil 26 is located outside the moisture-absorbing bladder 15, small water droplets will be adsorbed on its outer wall. The water flow formed by the accumulation of small water droplets will further cool the heat dissipation coil 26. As a result, the gaseous coolant inside the heat dissipation coil 26 will liquefy again and flow back along the heat dissipation coil 26 to the serpentine tube 27. The liquid coolant inside the serpentine tube 27 will undergo another heat absorption reaction to turn into a gaseous state, forming a continuous cooling cycle. This not only improves the heat dissipation efficiency but also makes full use of the water droplets adsorbed by the moisture-absorbing bladder 15. These water droplets can directly participate in the cooling process of the heat dissipation coil 26, thereby reducing the dependence on external water sources, enhancing the adaptability of the equipment in outdoor environments, and achieving efficient use of resources.
