Description

Technical Field

[0001] This application relates to the field of switchgear equipment technology, specifically a fixed AC metal-enclosed switchgear. Background Technology

[0002] A switchgear is an electrical device whose main function is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. It is suitable for various occasions such as power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, residential communities, and high-rise buildings. Switchgear can be further divided into high-voltage switchgear, medium-voltage switchgear, and low-voltage switchgear according to different voltage levels.

[0003] High-voltage switchgear generates a lot of heat during operation due to its high voltage level, so a heat dissipation structure is needed to cool it down.

[0004] For example, the utility model patent with announcement number CN215733083U specifically discloses a new type of heat dissipation switch cabinet. This patent implements heat dissipation operation of the switch cabinet by setting movable louvers and a cooling fan inside the heat dissipation device. At the same time, it is equipped with a winding cord and a winding roller to facilitate the opening and closing of the louvers, thereby achieving the purpose of adjusting the ventilation effect of the switch cabinet, adapting to heat dissipation operation under different conditions, and ensuring the heat dissipation effect of the switch cabinet during use.

[0005] In the implementation of the above patent, only a single cooling fan is used to dissipate heat from the switch cabinet. When the external temperature is high, the external airflow temperature is also high. The airflow alone cannot achieve a good heat dissipation effect, thus affecting the normal operation of the switch cabinet. Therefore, it is necessary to provide a fixed AC metal-enclosed switch cabinet to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0043] Example 1:

[0044] like Figure 1 As shown, this application provides a fixed AC metal-enclosed switchgear, including switchgear 1. The main electrical components inside the switchgear 1, such as circuit breakers, disconnect switches, grounding switches, transformers, surge arresters, busbars, secondary components, etc., are all enclosed in a metal shell. This structure gives the switchgear 1 advantages such as dustproof, moistureproof, prevention of small animals from entering, and prevention of arc fault expansion.

[0045] The switchgear 1 typically consists of a cabinet, busbar compartment, circuit breaker compartment, cable compartment, and instrument compartment. The cabinet is made of high-quality steel plate and has sufficient mechanical strength and protection level. The busbar compartment is used to install busbars, the circuit breaker compartment is used to install circuit breakers, the cable compartment is used to connect incoming and outgoing cables, and the instrument compartment is used to install measuring instruments and secondary components.

[0046] Switchgear 1 is widely used in power distribution and control fields of power systems in factories, mines, enterprises and institutions. It is suitable for AC circuits with various rated voltages and rated currents, and is used for power receiving, power feeding, motor control and lighting of power systems.

[0047] Switch cabinet 1 has a base structure, which can be firmly connected and fixed to the ground.

[0048] like Figures 1-2 As shown, a cooling mechanism 2 is provided on one side of the upper end of the switch cabinet 1. The cooling mechanism 2 includes an upper box 21 fixedly installed on the upper end of the switch cabinet 1. The upper box 21 has a hollow cavity (not shown in the figure) inside. It can be understood that the hollow cavity is connected to the upper end of the switch cabinet 1, so that the airflow in the switch cabinet 1 can enter the interior of the hollow cavity.

[0049] Meanwhile, a fan 22 is fixedly installed at the upper end of the upper box 21. The fan 22 is used to exhaust the airflow inside the hollow cavity. So when the switch cabinet 1 needs to dissipate heat, the fan 22 can be turned on to exhaust the hot airflow, thereby achieving heat dissipation of the switch cabinet 1.

[0050] To further improve the heat dissipation effect of switchgear 1, such as Figures 1-4As shown, a liquid cooling mechanism 4 is also provided on the upper box 21. The liquid cooling mechanism 4 includes a liquid tank 41 fixedly installed on the upper end of the upper box 21. A pump body 42 is connected to the output pipe of the liquid tank 41. A condenser 43 is connected to the output end of the pump body 42. A liquid cooling pipe 47 is connected to the output end of the condenser 43. The liquid cooling pipe 47 is distributed in the hollow cavity of the upper box 21, and the end of the liquid cooling pipe 47 is connected to the input end of the liquid tank 41. Thus, the liquid in the liquid tank 41 enters the condenser 43 for cooling through the action of the pump body 42. The cooled liquid flows into the liquid cooling pipe 47. Because the liquid cooling pipe 47 is distributed in the hollow cavity, the airflow passing through the hollow cavity can be liquid cooled, thereby allowing the temperature in the switch cabinet 1 to drop faster.

[0051] To allow the liquid cooling pipe 47 to move within the hollow cavity, so that it can cover most of the hollow cavity area and thus improve the liquid cooling effect, such as... Figures 3-5 As shown, a motor 44 is fixedly installed on the upper box 21. The output end of the motor 44 extends into the hollow cavity and a rotating shaft 45 is fixedly installed thereon. A connecting rod 412 is fixedly installed at the middle position of the rotating shaft 45. A driven shaft 46 is fixedly installed at the end of the connecting rod 412 away from the rotating shaft 45. Thus, when the motor 44 rotates, the rotating shaft 45 can rotate synchronously, thereby driving the driven shaft 46 to rotate in the hollow cavity. In this embodiment, the motor 44 can be a swing motor, so that the driven shaft 46 can swing at a set angle in the hollow cavity.

[0052] Meanwhile, the liquid cooling tube 47 is spirally wound between the rotating shaft 45 and the driven shaft 46, and a clamp 413 is provided on the liquid cooling tube 47 so that the liquid cooling tube 47 can be stably installed on the rotating shaft 45 and the driven shaft 46. At this time, the liquid cooling tube 47 can rotate together with the rotating shaft 45 and the driven shaft 46 to cover most of the area of ​​the hollow cavity, thereby making the liquid cooling effect better.

[0053] Example 2:

[0054] To prevent hot airflow entering the upper housing 21 from contaminating the fan 22 during the cooling of switch cabinet 1, such as... Figures 4-5 As shown, a filter plate 49 is hinged to the bottom of the upper box 21. The filter plate 49 is provided with multiple sets of mesh holes 491. The mesh holes 491 are used to filter the airflow in the hollow chamber of the upper box 21 when the switch cabinet 1 is cooling, so as to prevent impurities from contaminating the fan 22.

[0055] Meanwhile, a tail plate 410 is fixedly installed on the driven shaft 46. An elastic body 411 is connected between the tail plate 410 and the filter plate 49, so that when the driven shaft 46 rotates, the filter plate 49 can rotate synchronously.

[0056] In this embodiment, the connecting rod 412 is configured as a two-section telescopic rod, and an elastic tube 48 is provided on the liquid cooling pipe 47. Thus, when the filter plate 49 and the driven shaft 46 rotate synchronously, the elastic tube 48 and the two-section telescopic rod make the rotation of the filter plate 49 smoother.

[0057] It should be noted that the motor 44 in this embodiment is a common forward and reverse motor, not the swing motor of the first embodiment. Under normal circumstances, the motor 44 will not be started at will. Thus, when cooling the switch cabinet 1, the filter plate 49 always closes the lower end of the upper box 21 to purify the airflow. When it is necessary to clean the mesh 491 on the filter plate 49, since the filter plate 49 is located inside the switch cabinet 1, the motor 44 is needed to drive the filter plate 49 to rotate so that the filter plate 49 can reach a position that is easy to clean.

[0058] like Figure 1 , Figure 3 and Figure 6 As shown, a cleaning mechanism 3 is provided on one side of the switch cabinet 1. The cleaning mechanism 3 is mainly used for cleaning the filter plate 49. The cleaning mechanism 3 includes a side box 31 fixedly installed on one side of the switch cabinet 1. The side box 31 has a cavity inside, which is connected to the interior of the switch cabinet 1. It can be understood that the filter plate 49 can be rotated from the bottom of the upper box 21 to a vertical position, and this position is located at the connection between the side box 31 and the switch cabinet 1. Thus, when the filter plate 49 is in a vertical position, the cleaning mechanism 3 inside the side box 31 can perform a cleaning operation on the filter plate 49.

[0059] Meanwhile, a cylinder 32 is fixedly installed on the top of the side box 31. The output end of the cylinder 32 is vertically downward and extends into the cavity of the side box 31. A mounting part 321 is fixedly provided on the output end of the cylinder 32. A scraper 35 is fixedly installed on the mounting part 321. A scraper blade 351 is provided on one side of the scraper 35. Thus, in the initial state, the scraper 35 is in the upper position under the drive of the cylinder 32. When the filter plate 49 is in the vertical position, the cylinder 32 extends and drives the scraper 35 to move downward, and contacts the filter plate 49 through the scraper blade 351 to scrape off the impurities on the filter plate 49.

[0060] like Figure 10 As shown, a baffle 311 is provided at the bottom of the side box 31, thereby forming an opening at the top of the receiving groove (not shown in the figure) at the bottom of the side box 31, so that the impurities scraped by the scraper 351 can fall into the receiving groove to prevent the impurities from scattering everywhere.

[0061] Meanwhile, the bottom of the receiving tank is inclined, and a drain hole 312 is provided on one side of the lowest point of the bottom of the receiving tank. A water plug (not shown in the figure) is provided on the outside of the drain hole 312, so that clean water can be placed in the receiving tank under normal circumstances. When the scraper 35 moves down, it will come into contact with the clean water and leave the impurities in the clean water. Then the water plug can be pulled out to release the clean water after cleaning.

[0062] At the same time, the scraper 35 is reset after cleaning. Because the scraper 351 contains water, the filter plate 49 can be cleaned a second time, so that the filter plate 49 can be cleaned better.

[0063] In this embodiment, the liquid cooling pipes 47 are arranged directly opposite the mesh 491, which not only allows for more thorough contact between the airflow and the liquid cooling pipes 47 to enhance the cooling effect of the switch cabinet 1, but also allows the liquid cooling pipes 47 to completely block the mesh 491 to prevent water from entering the interior of the switch cabinet 1 during the secondary cleaning of the filter plate 49.

[0064] In this embodiment, in order to maintain the stability of the scraper 35, such as Figures 6-7 As shown, a vertical plate 36 is fixedly installed on the top of the side box 31. A slide rail 33 is fixedly installed on the vertical plate 36. A slider 34 is slidably arranged on the slide rail 33. The slider 34 is fixedly installed with the mounting part 321, so that when the mounting part 321 moves vertically, it can be guided by the cooperation of the slider 34 and the slide rail 33.

[0065] Meanwhile, a top plate 37 is fixedly installed on the top of the slide rail 33 to prevent the slider 34 from slipping off the top of the slide rail 33.

[0066] Example 3:

[0067] To further improve the cleaning effect of filter plate 49, such as Figures 6-9 As shown, a vibration mechanism 5 is provided on the mounting part 321. The vibration mechanism 5 can vibrate the filter plate 49 during the process of the scraper 351 scraping off impurities from the filter plate 49, so as to further improve the cleaning effect of the filter plate 49.

[0068] The vibration mechanism 5 includes a fixed ring 53 fixedly mounted on the mounting part 321. A locking shaft 54 ​​is slidably passed through the fixed ring 53. A toothed plate 56 is fixedly mounted on the locking shaft 54 ​​away from the fixed ring 53. At the same time, a first spring 55 is installed between the toothed plate 56 and the fixed ring 53, so that the locking shaft 54 ​​can slide on the fixed ring 53 to drive the toothed plate 56 to move horizontally synchronously. In this embodiment, a boss (not shown in the figure) is provided on the locking shaft 54 ​​to prevent the locking shaft 54 ​​from falling out of the fixed ring 53 when sliding.

[0069] Furthermore, a second rack 57 is provided at the lower end of the toothed plate 56. The second rack 57 meshes with the gear 52, so that when the gear 52 rotates, the toothed plate 56 can be driven to slide horizontally through the meshing second rack 57, and the first spring 55 can be stretched or compressed.

[0070] Continue to refer to Figures 9-10 A groove 561 is provided on the toothed plate 56. Independent teeth 58 are slidably provided at both ends of the groove 561 (only one end is shown in the figure). A second spring 59 is fixedly installed between the independent teeth 58 and the toothed plate 56. Thus, in the initial state, due to the action of the second spring 59, there is a certain distance between the independent teeth 58 and one end of the second rack 57. This distance is the tooth pitch length of the second rack 57.

[0071] Meanwhile, in order to drive the gear 52 to rotate, a vertical first rack 51 is fixedly provided on the slide rail 33, and the first rack 51 meshes with the gear 52;

[0072] In summary, in the initial state, the scraper 35 is located at the upper end, and the toothed plate 56 and the filter plate 49 are in a non-contact position.

[0073] When the scraper 35 moves downward to perform the cleaning action, the gear 52 also moves downward and meshes with the first rack 51 and begins to rotate. When the gear 52 rotates, it drives the toothed plate 56 to move horizontally and slowly approach the filter plate 49. When the gear 52 reaches the end of the second rack 57, the end of the toothed plate 56 contacts the filter plate 49.

[0074] When gear 52 passes the end of the second rack 57, it will mesh with independent tooth 58. After the second rack 57 meshes with independent tooth 58, it will drive independent tooth 58 to move closer to the second rack 57. Under the action of the second spring 59, it will drive tooth plate 56 to continue to move closer to filter plate 49.

[0075] As gear 52 continues to rotate, when gear 52 disengages from independent tooth 58, independent tooth 58 will reset under the action of second spring 59, and drive tooth plate 56 to reset short distance, so that the end of tooth plate 56 moves away from the filter plate.

[0076] Thus, through the continuous rotation of the gear 52, the gear 52 and the independent tooth 58 can be intermittently meshed, so as to drive the end of the toothed plate 56 to intermittently collide with the filter plate 49. As the scraper 351 contacts the filter plate 49, the constantly colliding toothed plate 56 makes it easier for impurities on the filter plate 49 to fall off, thereby enhancing the cleaning effect of the filter plate 49.

[0077] When the scraper 35 returns to its original position, the gear 52 also moves upward and meshes with the first rack 51, and begins to rotate in the opposite direction. When the gear 52 rotates in the opposite direction, it drives the toothed plate 56 to move horizontally and slowly move away from the filter plate 49. Thus, when the wet scraper 351 cleans the filter plate 49 for the second time, the toothed plate 56 will not collide with the filter plate 49, thereby preventing water from splashing everywhere.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
