[0025] Specifically, first, the pressing plate 4 is driven to slide inside the guide rail 3. This action applies pressure to the card block 6, so that the card block 6 slides inside the guide rail 3 and the mounting plate 5. The movement of the card block 6 further drives the sliding rod 7 to slide inside the mounting plate 5, and at the same time, the spring 11 contracts inside the mounting plate 5. Next, through the movement of the sliding rod 7, the rack 8 on its inner wall also moves accordingly. Since there is a meshing relationship between the rack 8 and the gear 9, the movement of the rack 8 causes the gear 9 to start rotating, and the rotation of the gear 9 further drives The card block 6 on the other side is moved. When the card blocks 6 on both sides are completely moved to the inside of the mounting plate 5, the outer shell 1 can be pulled at this time to make the mounting plate 5 slide on the inner wall of the guide rail 3, so that a single dry-type transformer can be easily removed for subsequent maintenance work. During installation, it is only necessary to re-place the two ends of the mounting plate 5 on the inner wall of the guide rail 3 and slide them to the appropriate position, and then through the rebound effect of the spring 11, the card block 6 is pushed to be stuck into the inside of the guide rail 3 again, completing the installation of the dry-type transformer and achieving the effect of disassembly and assembly.

[0026] Reference Figure 3 and Figure 4 The bottom height of the support frame 2 is connected with a fan 14, a filter plate 15 is slidably connected inside the support frame 2, and a triangular buckle 16 is fixedly connected to the outer wall of the filter plate 15, and the outer wall of the triangular buckle 16 is slidably connected to the inside of the support frame 2, and a clamping plate 17 is slidably connected to the inside of the support frame 2, and a special-shaped plate 20 is fixedly connected to one side of the outer wall of the clamping plate 17, and a telescopic rod 2 18 is fixedly connected to the other side of the outer wall of the clamping plate 17, and the outer wall of the special-shaped plate 20 is slidably connected to the inside of the support frame 2, and the outer wall of the telescopic rod 2 18 is sleeved with a spring 2 19, one end of the spring 2 19 is fixedly connected to the outer wall of the clamping plate 17, and the other end of the spring 2 19 is fixedly connected to the inside of the support frame 2, and the inside of the support frame 2 is rotatably connected with a slide rod 21, and one end of the slide rod 21 is fixedly connected to a push plate 22, and the outer wall of the push plate 22 is rotatably connected to the inside of the support frame 2;

[0027] Specifically, the fan 14 is first installed at the bottom of the support frame 2, absorbs air from the surrounding environment, and then guides and blows it to the dry-type transformer, thereby effectively dissipating heat for it. In this process, the filter plate 15 prevents dust, particles or other impurities in the air from entering the interior of the support frame 2, thereby protecting the dry-type transformer from pollution. When it is necessary to clean or replace the filter plate 15, it can be operated by rotating the slide bar 21. The rotation of the slide bar 21 will drive the push plate 22 to rotate accordingly inside the support frame 2. The rotation of the push plate 22 will apply pressure to the special-shaped plates 20 on both sides, so that the special-shaped plates 20 further push the clamping plate 17 The filter plate 15 can be taken out of the support frame 2 by sliding inside the support frame 2, which is convenient for cleaning or replacement. When installing a new filter plate 15, it is only necessary to align the raised blocks on both sides of the filter plate 15 with the inside of the support frame 2 and insert it. As the filter plate 15 is inserted, the triangular buckle 16 will move to the inside of the support frame 2. At this time, the spring 2 19 starts to play a role, which will push the clamping plate 17 to move, so that the raised part of the clamping plate 17 clamps the triangular buckle 16. In this way, the new filter plate 15 is firmly installed in the support frame 2, which not only ensures the effective heat dissipation of the dry-type transformer, but also makes it easy to clean and replace the filter plate 15.

[0028] Working principle: when it is necessary to use an easily detachable dry-type transformer, first drive the pressing plate 4 to slide inside the guide rail 3, thereby applying pressure to the card block 6, so that the card block 6 slides inside the guide rail 3 and the mounting plate 5, and the movement of the card block 6 drives the sliding rod 7 to slide inside the mounting plate 5, and at the same time, the spring 11 contracts inside the mounting plate 5, and then the rack 8 on the inner wall is driven to move by the movement of the sliding rod 7, and then the gear 9 is meshed with the rack 8 to rotate with the movement of the gear 8, and then the card block 6 on the other side is driven to move by the rotation of the gear 9. When the card blocks 6 on both sides are completely moved to the inside of the mounting plate 5, the outer shell 1 can be pulled to make the mounting plate 5 slide on the inner wall of the guide rail 3, so that a single dry-type transformer can be removed for inspection. During installation, you only need to slide the two ends of the mounting plate 5 on the inner wall of the guide rail 3, and then through the spring 11 The rebound of 11 pushes the card block 6 to get into the inside of the guide rail 3, achieving the effect of disassembly and assembly, and then the fan 14 at the bottom of the support frame 2 absorbs the external air and blows it to the dry-type transformer to dissipate heat for the dry-type transformer. In this process, the air is filtered by the filter plate 15, and then the push plate 22 is driven to rotate inside the support frame 2 by rotating the slide bar 21, and then the special-shaped plates 20 on both sides are pressed by the rotation of the push plate 22, so that the special-shaped plates 20 drive the clamping plate 17 to slide inside the support frame 2, so that the filter plate 15 can be removed for cleaning or replacement. During installation, it is only necessary to align the raised blocks on both sides of the filter plate 15 with the inside of the support frame 2 and insert them to move the triangular buckle 16 to the inside of the support frame 2. At this time, the clamping plate 17 is pushed to move by the spring 2 19, so that the raised part of the clamping plate 17 clamps the triangular buckle 16, thereby realizing the disassembly and assembly of the filter plate 15.
