Description

Technical Field

[0001] The present application relates to the technical field of switchgear equipment, and specifically to a fixed AC metal-enclosed switchgear. Background Art

[0002] Switchgear is an electrical equipment whose main function is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. It is suitable for various occasions such as power plants, substations, petrochemical industry, metallurgy and steel rolling, light industry and textile, factories and mines, residential areas, high-rise buildings, etc. Switchgear can be divided into high-voltage switchgear, medium-voltage switchgear and low-voltage switchgear according to different voltage levels.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0023] Example 1: like Figure 1As shown, the present application provides a fixed AC metal-enclosed switchgear, including a switchgear 1. The main electrical components inside the switchgear 1, such as circuit breakers, disconnectors, earthing switches, mutual inductors, lightning arresters, busbars, secondary components, etc., are all enclosed in a metal casing. This structure makes the switchgear 1 dustproof, moisture-proof, and prevent small animals from entering, and prevents arc faults from expanding. The switch cabinet 1 is generally composed of a cabinet body, a busbar compartment, a circuit breaker compartment, a cable compartment, an instrument compartment, and other parts. The cabinet body is made of high-quality steel plates and has sufficient mechanical strength and protection level. The busbar compartment is used to install the busbar, the circuit breaker compartment is used to install the circuit breaker, the cable compartment is used to connect the incoming and outgoing cables, and the instrument compartment is used to install measuring instruments and secondary components. The switchgear 1 is widely used in the power distribution and control fields of power systems in factories, mines, enterprises and institutions. It is suitable for AC circuits of various rated voltages and rated currents, and is used for power receiving, feeding, motor control and lighting of power systems. The switch cabinet 1 has a foot structure, which can be firmly connected and fixed to the ground.

[0024] like Figure 1-Figure 2 As shown, an air cooling mechanism 2 is provided on one side of the upper end of the switch cabinet 1. The air cooling mechanism 2 includes an upper box 21 fixedly mounted on the upper end of the switch cabinet 1. A hollow chamber (not shown in the figure) is provided inside the upper box 21. It is understood that the hollow chamber 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 chamber. At the same time, a fan 22 is fixedly installed at the upper end of the upper box 21. The fan 22 is used to guide the airflow inside the hollow chamber. When the switch cabinet 1 needs to dissipate heat, it only needs to turn on the fan 22 to guide the hot air flow out, thereby achieving heat dissipation of the switch cabinet 1.

[0025] In order to further improve the heat dissipation effect of the switch cabinet 1, Figures 1-4 As shown, a liquid cooling mechanism 4 is further provided on the upper box 21, and the liquid cooling mechanism 4 includes a liquid tank 41 fixedly mounted on the upper end of the upper box 21, an output pipe of the liquid tank 41 is connected to a pump body 42, an output end of the pump body 42 is connected to a condenser 43, and an output end of the condenser 43 is connected to a liquid cooling pipe 47, the liquid cooling pipe 47 is distributed in the hollow chamber 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, so that the liquid in the liquid tank 41 enters the condenser 43 for cooling through the action of the pump body 42, and the cooled liquid flows into the liquid cooling pipe 47. Because the liquid cooling pipe 47 is distributed in the hollow chamber, the airflow passing through the hollow chamber can be liquid-cooled, thereby allowing the temperature in the switch cabinet 1 to drop faster; In order to allow the liquid cooling tube 47 to move in the hollow chamber, so that the liquid cooling tube 47 can cover most areas of the hollow chamber, so as to achieve better liquid cooling effect, such as Figure 3-Figure 5 As shown, a motor 44 is fixedly mounted on the upper box 21, and the output end of the motor 44 extends into the hollow chamber and is fixedly mounted with a rotating shaft 45. A connecting rod 412 is fixedly mounted in the middle position of the rotating shaft 45, and a driven shaft 46 is fixedly mounted on the end of the connecting rod 412 away from the rotating shaft 45. When the motor 44 rotates, the rotating shaft 45 can rotate synchronously, thereby driving the driven shaft 46 to rotate in the hollow chamber. 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 chamber. At the same time, 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 with the rotating shaft 45 and the driven shaft 46 to cover most of the area of ​​the hollow chamber, thereby making the liquid cooling effect better.

[0026] Example 2: In order to prevent the hot air flow entering the upper box 21 from contaminating the fan 22 when cooling the switch cabinet 1, Figure 4-Figure 5 As shown, a filter plate 49 is hinged at the bottom of the upper box 21. The filter plate 49 is provided with multiple groups 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 cooled, so as to prevent impurities from contaminating the fan 22. At the same time, a tail plate 410 is fixedly mounted on the driven shaft 46, and 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; 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 tube 47. Thus, when the filter plate 49 and the driven shaft 46 rotate synchronously, the elastic tube 48 and the two-section telescopic rod can make the filter plate 49 rotate more smoothly. It should be noted that the motor 44 in this embodiment is an ordinary forward and reverse motor, rather than the swing motor of the first embodiment, and under normal circumstances, the motor 44 will not be started at will, so that when the switch cabinet 1 is cooled, the filter plate 49 always closes the lower end of the upper box 21 to purify the airflow. When the mesh 491 on the filter plate 49 needs to be cleaned, because the filter plate 49 is located inside the switch cabinet 1, it is necessary to drive the filter plate 49 to rotate by the motor 44 so that the filter plate 49 reaches a position that is convenient for cleaning. like Figure 1 、 Figure 3 and Figure 6As 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 mounted on one side of the switch cabinet 1. A cavity is provided inside the side box 31, and the cavity is communicated with 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. Therefore, when the filter plate 49 is in the vertical position, the cleaning mechanism 3 inside the side box 31 can clean the filter plate 49. At the same time, 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 portion 321 is fixedly provided at the output end of the cylinder 32. A scraper 35 is fixedly mounted on the mounting portion 321. A scraper 35 is provided on one side of the scraper 35. In the initial state, the scraper 35 is in the upper end position driven by 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 351 to scrape impurities on the filter plate 49. like Figure 10 As shown, a baffle 311 is provided at the bottom of the side box 31, thereby forming a receiving groove (not shown in the figure) with an open top 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 floating around; The bottom of the receiving tank is inclined, and a water leakage 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 outside the water leakage hole 312, so that clean water can be placed in the receiving tank under normal circumstances. When the scraper 35 moves downward, it will come into contact with the clean water and retain impurities in the clean water. The water plug can then be pulled out to release the clean water after cleaning. At the same time, the scraper 35 is reset after cleaning is completed. Since the scraper 351 contains moisture, the filter plate 49 can be cleaned for the second time, thereby achieving a better cleaning effect of the filter plate 49. In this embodiment, the arrangement of the liquid cooling tube 47 is completely opposite to the position of the mesh 491, so that not only can the air flow contact with the liquid cooling tube 47 be more complete to enhance the cooling effect of the switch cabinet 1, but the liquid cooling tube 47 can also completely block the mesh 491 to prevent water splashes from entering the interior of the switch cabinet 1 during the secondary cleaning of the filter plate 49.

[0027] In this embodiment, in order to maintain the stability of the scraper 35, as shown in FIG. Figure 6-Figure 7As shown, a vertical plate 36 is fixedly mounted on the top of the side box 31, a slide rail 33 is fixedly mounted on the vertical plate 36, a slider 34 is slidably mounted on the slide rail 33, and the slider 34 is fixedly mounted on the mounting portion 321, so that when the mounting portion 321 moves vertically, it can be guided by the cooperation between the slider 34 and the slide rail 33; At the same time, a top plate 37 is fixedly installed on the top of the slide rail 33 to prevent the slider 34 from slipping off the upper end of the slide rail 33.

[0028] Example 3: In order to further improve the cleaning effect of the filter plate 49, as Figure 6-Figure 9 As shown, a vibration mechanism 5 is provided on the mounting portion 321. The vibration mechanism 5 can vibrate the filter plate 49 during the process of the scraper 351 scraping impurities from the filter plate 49, so as to further improve the cleaning effect of the filter plate 49; The vibration mechanism 5 includes a fixing ring 53 fixedly mounted on the mounting portion 321, a locking shaft 54 ​​slidably penetrated through the fixing ring 53, a toothed plate 56 fixedly mounted on the locking shaft 54 ​​away from the fixing ring 53, and a first spring 55 installed between the toothed plate 56 and the fixing ring 53, so that the locking shaft 54 ​​can slide on the fixing ring 53 to drive the toothed plate 56 to move horizontally in synchronization. In this embodiment, a boss (not shown) is provided on the locking shaft 54 ​​to prevent the locking shaft 54 ​​from falling off the fixing ring 53 when sliding. A second rack 57 is provided at the lower end of the toothed plate 56. The second rack 57 is meshed with the gear 52. When the gear 52 rotates, the meshed second rack 57 drives the toothed plate 56 to slide horizontally, thereby stretching or compressing the first spring 55. Continue to refer Figure 9-10 A slide groove 561 is provided on the tooth plate 56, and independent teeth 58 are slidably provided at both ends of the slide groove 561 (only one end is shown in the figure), and a second spring 59 is fixedly installed between the independent tooth 58 and the tooth plate 56. Therefore, in the initial state, due to the action of the second spring 59, the independent tooth 58 and one end of the second rack 57 have a certain distance, which is the tooth pitch length of the second rack 57; At the same time, 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 is engaged with the gear 52; In summary, in the initial state, the scraper 35 is at the upper end position, and the tooth plate 56 and the filter plate 49 are in a non-contact position; When the scraper 35 moves downward to perform a 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 tooth 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 tooth plate 56 contacts the filter plate 49. When the gear 52 passes the end of the second rack 57, it will mesh with the independent tooth 58. After the second rack 57 meshes with the independent tooth 58, it will drive the independent tooth 58 to move closer to the second rack 57. Under the action of the second spring 59, it will drive the tooth plate 56 to continue to move closer to the filter plate 49. As the gear 52 continues to rotate, when the gear 52 is disengaged from the independent tooth 58, the independent tooth 58 will be reset under the action of the second spring 59, and drive the tooth plate 56 to reset a short distance, so that the end of the tooth plate 56 moves away from the filter plate; Thus, through the continuous rotation of the gear 52, the gear 52 and the independent teeth 58 can be intermittently engaged, so as to drive the end of the tooth plate 56 to intermittently collide with the filter plate 49. As a result, during the contact process between the scraper 351 and the filter plate 49, the continuous collision of the tooth 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. When the scraper 35 is reset upward, the gear 52 also moves upward and engages with the first rack 51 and starts to rotate in the opposite direction. When the gear 52 rotates in the opposite direction, it drives the tooth plate 56 to move horizontally and slowly move away from the filter plate 49. Therefore, when the wet scraper 351 cleans the filter plate 49 for the second time, the tooth plate 56 will not collide with the filter plate 49, thereby preventing water from splashing everywhere.

[0029] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
