[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments 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 any creative efforts are within the scope of protection of the present invention.

[0020] The embodiment of the present application provides a bushing riser for a transformer, which solves the problem that the existing bushing riser is generally cylindrical and uses a material with high insulation strength as the lining, which causes the temperature inside the seat to easily rise and be unable to dissipate, ultimately leading to safety accidents such as explosions.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] The embodiment of the utility model discloses a bushing raising seat for a transformer.

[0023] According to the attached Figure 1-6 As shown, it includes a lifting seat cylinder 1, a supporting fixture 3 is fixedly installed in the lifting seat cylinder 1, an annular heat sink 2 is fixedly connected to the outer end of the lifting seat cylinder 1, a heat dissipation fin 21 is fixedly connected to the outer end of the lifting seat cylinder 1, and the heat dissipation fin 21 is fixedly connected to the bottom of the annular heat sink 2. The annular heat sink 2 is hoop-shaped as a whole, and the thickness of the annular heat sink 2 close to the lifting seat cylinder 1 is large, and the thickness of the annular heat sink 2 away from the lifting seat cylinder 1 is small. The upper end of the outer side of the annular heat sink 2 is tilted downward, and the annular heat sink 2 is distributed in an array outside the lifting seat cylinder 1. At the same time, since the annular heat sink 2 is close to the lifting seat cylinder One end of the high seat tube 1 is thicker, and the end of the annular heat sink 2 away from the elevated seat tube 1 is thinner, so that the strength of the annular heat sink 2 is guaranteed, and there will be no damage to the parts due to external natural conditions and human touch. At the same time, the heat dissipation fins 21 also provide support for the annular heat sink 2, and the heat dissipation fins 21 themselves also have thermal conductivity and heat dissipation properties, further increasing the heat dissipation performance of the elevated seat tube 1. The upper end of the outer side of the annular heat sink 2 is tilted downward so that raindrops falling on it on rainy days can fall on the inclined upper plate without being contaminated on the elevated seat tube 1, thereby preventing accidents.

[0024] The top of the lifting seat cylinder 1 is fixedly connected to the lower flange 12 of the cover plate, the top flange of the lower flange 12 of the cover plate is connected to the upper flange 11 of the cover plate, the bottom of the lifting seat cylinder 1 is fixedly connected to the lifting seat flange 14, the upper end of the outer surface of the lifting seat cylinder 1 is fixedly connected to the lifting ear 13, and the inside of the lifting seat cylinder 1 is fixedly connected to the slider 15. The functions of the lower flange 12 of the cover plate and the flange 11 on the cover plate are used to fix and seal the transformer bushing, and the function of the lifting seat flange 14 is to fix the lifting seat cylinder 1 on the box body.

[0025] The supporting fixing part 3 includes a supporting sleeve 31, an insulating sleeve 32 and a fixing ring 33. The insulating sleeve 32 is sleeved in the supporting sleeve 31, and the fixing ring 33 is fixedly connected to the bottom of the supporting sleeve 31. A sliding groove 311 is provided on the outer surface of the supporting sleeve 31, and the slider 15 is slidably connected in the sliding groove 311. The supporting sleeve 31 is used to enhance the strength of the lifting seat tube 1 and isolate the inside and outside to prevent electric shock from penetrating the outer wall and causing safety accidents. The insulating sleeve 32 provides an insulating effect to prevent accidents. The fixing ring 33 fixes the supporting sleeve 31 and the insulating sleeve 32 in the lifting seat tube 1.

[0026] In summary, compared with the existing technology, the present invention has the following beneficial effects:

[0027] By fixing the annular heat sink 2 on the outer wall of the lifting seat tube 1, the heat dissipation performance of the bushing lifting seat for the transformer is improved. At the same time, due to the hoop shape of the annular heat sink 2, the structural strength of the lifting tube seat is enhanced. The heat dissipation fins 21 are used to support the annular heat sink 2, and their own heat dissipation properties further enhance the heat dissipation performance of the bushing lifting seat for the transformer, so that the temperature of the bushing lifting seat for the transformer cannot be increased, thereby improving safety.
