[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, a gas-insulated ring network cabinet includes a first ring network cabinet 1 and a second ring network cabinet 2. The gas-insulated ring network cabinet achieves gas insulation by using a gas such as SF6 as the main insulation between the live parts and the grounded metal casing. The first ring network cabinet 1 and the second ring network cabinet 2 are fixedly installed with a first top plate 3 and a second top plate 4 on the upper side. The left side of the two second top plates 4 is installed with an array of positioning columns 5. The interior of the two first top plates 3 is provided with a through card slot 6. The rear side of the first ring network cabinet 1 and the second ring network cabinet 2 is installed with a fixing block 7.

[0028] One side of the two fixed blocks 7 is slidably connected with a movable card plate 8, and both ends of the two movable card plates 8 are slidably connected with a telescopic slide rod 11. A first spring 12 is connected between the four telescopic slide rods 11 and the movable card plates 8. The upper sides of the two movable card plates 8 are clamped with a vertical plug rod 10. One side of the two movable card plates 8 is fixedly connected with a plug plate 9. The rear sides of the first ring network cabinet 1 and the second ring network cabinet 2 are fixedly installed with a U-shaped connecting plate 13. Through the setting of the telescopic slide rod 11, the two telescopic slide rods 11 with elastic force are pressed at the U-shaped connecting plate 13, so that the two telescopic slide rods 11 can be retracted to release the limit on the movable card plate 8 and remove the movable card plate 8, which is easy to use.

[0029] The front sides of the first ring network cabinet 1 and the second ring network cabinet 2 are fixedly connected with a U-shaped seat 24, and the inner sides of the two U-shaped seats 24 are rotatably connected with a sealed cabinet door 14 for sealing the gas insulated ring network cabinet. The right sides of the two sealed cabinet doors 14 are installed with an embedded plate 15, and the two embedded plates 15 are connected with rubber convex strips 16 around them. The left sides of the two U-shaped seats 24 are slidably connected with a limit plate 23 for fixing the sealed cabinet door 14. Through the setting of the limit plate 23, the limit plate 23 can be used to block the front of the sealed cabinet door 14, so that the sealed cabinet door 14 will not be easily loosened and opened. The right side of the limit plate 23 passes through the U-shaped seat 24 and extends to the right side of the U-shaped seat 24.

[0030] Two raised bases 17 are installed on the lower sides of the first ring network cabinet 1 and the second ring network cabinet 2. By setting the raised base 17, the height of the gas insulated ring network cabinet can be increased by utilizing the raised base 17, so that heat can be dissipated in time. The lower sides of the first ring network cabinet 1 and the second ring network cabinet 2 are fixedly connected to two base plates 18, and one side of the four base plates 18 is slidably connected to an active clamping rod 19. A second spring 20 is connected between the four active clamping rods 19 and the base plates 18. One side of the active clamping rod 19 passes through the base plate 18 and extends to the other side of the base plate 18. The inner sides of the two active clamping rods 19 are clamped with side panels 21, and the inner sides of the two side panels 21 are fixed with a cooling fan body 22.

[0031] The positioning column 5 is used to fix the No. 1 top plate 3. The lower side of the vertical insertion rod 10 passes through the movable card plate 8 and extends to the lower side of the movable card plate 8. A through circular groove 101 is opened inside the fixed block 7. The vertical insertion rod 10 is used to fix the movable card plate 8 and the fixed block 7.

[0032] Both ends of the U-shaped connecting plate 13 are provided with an embedding groove 25 , which is adapted to the telescopic slide rod 11 . The outer surface of the telescopic slide rod 11 is slidably engaged with both ends of the U-shaped connecting plate 13 through the embedding groove 25 .

[0033] A mounting groove 26 is defined inside the U-shaped connecting plate 13 , and the mounting groove 26 is adapted to the plugging plate 9 . The left side of the plugging plate 9 is engaged with the inside of the U-shaped connecting plate 13 through the mounting groove 26 .

[0034] Annular grooves 222 are provided inside the first ring main unit 1 and the second ring main unit 2 , which match the rubber convex strips 16 . The rubber convex strips 16 are connected to the inside of the first ring main unit 1 and the second ring main unit 2 via the annular grooves 222 .

[0035] The working principle of a gas insulated ring main unit provided by the utility model is as follows:

[0036] When the two ring network cabinets are put together, the positioning column 5 at the second top plate 4 can be inserted into the card slot 6 of the first top plate 3, so that the two ring network cabinets can be initially clamped and fixed. Then, the two telescopic slide bars 11 with the first spring 12 installed on the movable card plate 8 are compressed, and the movable card plate 8 at the fixed block 7 is pushed to move, so that the plug plate 9 at the movable card plate 8 can be clamped into the installation groove 26 of the U-shaped connecting plate 13. Then, the two telescopic slide bars 11 are released, and the two telescopic slide bars 11 with elastic force can automatically be embedded in the embedding groove 25 of the U-shaped connecting plate 13, so as to further assemble and fix the two gas insulated ring network cabinets. Then, the vertical plug rod 10 is inserted into the fixed block 7 and the movable card plate 8, so that the vertical plug rod 10 firmly positions the movable card plate 8, ensuring the stability of the two gas insulated ring network cabinets when installed side by side, avoiding the ring network cabinets from tipping over and injuring people, and improving the safety of the gas insulated ring network cabinets when placed;

[0037] By allowing the sealed cabinet door 14 to drive the embedded plate 15 into the interior of the ring network cabinet, the rubber ridge 16 on the embedded plate 15 can be just embedded in the annular groove 222. In this way, the rubber ridge 16 can play a sealing role, which is used to seal the ring network cabinet and improve the sealing ability of the gas insulated ring network cabinet. At the same time, the limit plate 23 is pushed so that the limit plate 23 can be positioned at the sealed cabinet door 14, so that the sealed cabinet door 14 can be more stable and reliable, preventing the sealed cabinet door 14 from loosening and affecting the sealing of the ring network cabinet. Then, the two cooling fan bodies 22 are respectively placed in the first ring network cabinet 1 and the second ring network cabinet 2, so that the two side panels 21 at the cooling fan body 22 can be clamped to the two movable clamping rods 19 installed with the second spring 20, so as to fix the cooling fan body 22 by clamping, so that the cooling fan body 22 can blow air to cool the bottom of the ring network cabinet, so that the heat can be quickly transferred out, thereby improving the heat dissipation effect of the gas insulated ring network cabinet.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
