Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly gas ring network cabinets, in particular to an environmentally friendly gas ring network cabinet which is convenient for cleaning a filter screen. Background Art

[0002] The environmentally friendly gas-insulated ring main unit (GINS) is a high-voltage switchgear that uses environmentally friendly gas as the insulating medium instead of traditional SF6 gas. It is environmentally friendly, does not produce hazardous substances such as perfluorinated compounds, and can effectively reduce global greenhouse gas emissions. It is currently widely used internationally as an environmentally friendly high-voltage switchgear.

[0003] At present, since many cables are used in environmentally friendly gas-insulated ring main unit (RMU), timely heat dissipation is required. Therefore, an air intake slot is provided on the RMU to be used with a fan to introduce external air into the RMU, thereby achieving internal and external air flow and reducing the temperature inside the RMU. At the same time, in order to prevent dust or insects in the air from entering the RMU through the air intake slot, a filter is installed on the air intake slot. However, once the filter is clogged, the air intake rate will be affected.

[0004] The existing public technical solution, with announcement number CN221080676U, discloses an environmentally friendly gas ring network cabinet, including a ring network cabinet body, an L-shaped connecting frame fixedly connected to the inside of the ring network cabinet, a motor fixedly connected to one side of the L-shaped connecting frame, and a transmission frame fixedly connected to the output end of the motor. The transmission frame is Z-shaped, and a fan is fixedly connected to the surface of the transmission frame. A transmission cleaning device is provided inside the movable groove. Impurities attached to the surface of the filter are cleaned by two sets of cleaning frames on the transmission cleaning device, and the impurities attached to the filter are reduced to a certain extent, causing the mesh of the filter to be blocked, thereby reducing the speed of gas passing through the mesh of the filter.

[0005] When the above technical solution is actually implemented, the filter is cleaned by a brush that can move back and forth. The brush repeatedly rubs and collides with the filter. In the long run, it will cause the mesh to deform and lose its original filtering performance. The cleaning effect is average.

[0030] The quick-release assembly 4 includes a limiting rod 407 adapted to the limiting slot 6 , and the limiting rod 407 passes through the outer wall of the filter box 501 .

[0031] By adopting the above technical solution, the detachable filter box assembly 5 is inserted into the limiting slot 6 through the limiting rod 407, which facilitates the disassembly of the filter box assembly 5. At the same time, the detachable filter plate 1 505 and the filter plate 2 506 are arranged in the filter box assembly 5 to filter the incoming air, and the filter box assembly 5 and the filter plate 1 505 and the filter plate 2 506 in the filter box assembly 5 can be removed without using other auxiliary tools, which facilitates the replacement of the filter plate 1 505 and the filter plate 2 506.

[0032] Specifically, such as Figure 3 and Figure 4 As shown, an exhaust fan 2 is fixedly installed on the top of the ring network cabinet body 1, and an air outlet 7 is provided at the connection between the exhaust fan 2 and the ring network cabinet body 1. The filter box assembly 5 also includes connecting screws 503 welded to the four corners of the filter box body 501, and the surface of the connecting screw 503 is threadedly connected to a limiting screw ring 502. The four corners of the filter plate 1 505 and the filter plate 2 506 are provided with connecting holes 504 that are compatible with the connecting screw 503, and the connecting screw 503 passes through the inside of the connecting hole 504.

[0033] By adopting the above technical solution, a protective shell is provided on the outside of the vacuum pump 2 and fixedly installed on the top of the ring network cabinet body 1. The vacuum pump 2 extracts the air in the ring network cabinet body 1 through the air outlet 7 and discharges it. As the air in the ring network cabinet body 1 is reduced, the external air enters the ring network cabinet body 1 through the filter box assembly 5, thereby realizing internal and external air circulation and dissipating the heat of the ring network cabinet body 1. After the filter plate 1 505 and the filter plate 2 506 are put on the outside of the connecting screw 503 through the connecting hole 504, the filter plate 1 505 and the filter plate 2 506 are fixed by the connecting screw 503, and the limiting screw ring 502 is installed on the connecting screw 503 to lock the filter plate 1 505 and the filter plate 2 506 to prevent the filter plate 1 505 and the filter plate 2 506 from shaking.

[0034] Specifically, such as Figure 2 As shown, the quick-release assembly 4 also includes a knob 401 installed on the surface of the filter box 501, and a rotating rod 402 is provided on one side of the knob 401 and passes through the interior of the filter box 501. The end of the rotating rod 402 is fixedly connected to a transmission spur gear 404, and the left and right sides of the transmission spur gear 404 are meshed with support gear rods 403, and the support gear rod 403 is slidably arranged inside the filter box 501, and the support gear rod 403 is fixedly connected to a limiting card rod 407 that passes through the filter box 501. A limiting plate 405 with a diameter larger than the limiting card rod 407 is provided between the supporting gear rod 403 and the limiting card rod 407, and a connecting spring 406 is provided on the surface of the limiting card rod 407, and the two ends of the connecting spring 406 are respectively connected to the limiting plate 405 and the inner wall of the filter box 501.

At this time, the rotary rod 402 drives the transmission spur gear 404 to rotate. As the transmission spur gear 404 rotates, the supporting gear rods 403 on both sides move one group upward and one group downward. The support gear rods 403 can pull the limit plate 405 and the limit rod 407 to move synchronously, so that the limit rod 407 is disengaged from the limit slot 6. Since one end of the connecting spring 406 is fixed in the filter box 501, the support gear rod 403 moves to stretch the pulling connecting spring 406. After the knob 401 is released, the limit rod 407 can be driven to reset under the action of the connecting spring 406.

[0036] Working principle: The vacuum pump 2 can extract the air in the ring main unit cabinet 1 through the air outlet 7 and discharge it out. As the air in the ring main unit cabinet 1 decreases, the external air enters the ring main unit cabinet 1 through the filter box assembly 5, thereby realizing the internal and external air circulation and dissipating the heat of the ring main unit cabinet 1. Turning the knob 401 can drive the rotary rod 402 to rotate. At this time, the rotary rod 402 drives the transmission spur gear 404 to rotate. As the transmission spur gear 404 rotates, the supporting gear rods 403 on both sides pull the limit plate 40 5 and the limiting card rod 407 move synchronously, so that the limiting card rod 407 is disengaged from the limiting card slot 6, and the filter box 501 is disassembled. After the filter plate 1 505 and the filter plate 2 506 are sleeved on the outside of the connecting screw 503 through the connecting hole 504, the filter plate 1 505 and the filter plate 2 506 are fixed by the connecting screw 503, and the limiting screw ring 502 is installed on the connecting screw 503 to lock the filter plate 1 505 and the filter plate 2 506 to prevent the filter plate 1 505 and the filter plate 2 506 from shaking.
