Embodiment 1

[0036] This embodiment provides an air cooling assembly for a transformer room, including a fan 7 and a bracket assembly for fixing the fan 7, such as figure 2 and 3 As shown, the bracket assembly includes a cantilever 1, a fixed box 2 and a plurality of guide tubes 3. The top of the cantilever 1 is used to be detachably fixed on the top of the transformer chamber. The cantilever 1 adopts a cylindrical structure. The top of the cantilever 1 can be welded to the 1 An axially vertical mounting plate, which is fixed on the top of the transformer room by bolts; each diversion tube 3 is a round tube, and multiple diversion tubes 3 are adjacent to each other along the circumferential direction of the cantilever 1 so that multiple diversion tubes 3. The overall structure is a circular tube structure, and the axial direction of the circular tube structure, the axial direction of the draft tube 3, and the axial direction of the cantilever 1 are in the same direction. The top ends of ...

Embodiment 2

[0038] Further improvement on the basis of Example 1, the inner wall of the ring plate I4 extends outward along the axial direction of the cantilever 1 to form a connecting sleeve 8, and a through hole is opened on the connecting sleeve 8, and the bolt is nailed in after passing through the through hole. Fixed on the side wall of the cantilever 1. A plurality of threaded holes are arranged on the side wall of the cantilever 1, and the plurality of threaded holes are evenly distributed along the axial direction of the cantilever 1, and each threaded hole is used for screwing in a bolt.

[0039] The ring plate II5 is connected with the fixed box 2 through the rotating joint 9; the rotating joint 9 includes a rotating cylinder I91 and a rotating cylinder II92, one end of the rotating cylinder I91 is fixed on the ring plate II5, and the other end extends into one end of the rotating cylinder II92, and the rotating cylinder The other end of the II92 is connected to the top of the f...

Embodiment 3

[0042] It is further improved on the basis of Embodiment 2, the difference lies in the connection mode of the rotating drum I91 and the rotating drum II92 and the structure of the fixing box 2 is different. The outer wall of the bottom end of the drum I91 is provided with a limit ring I93 in the circumferential direction. On the axial section of the drum I91, the limit ring I93 and the side wall of the drum I91 are L-shaped; the inner side of the top of the drum II92 is The wall is provided with a limiting ring II94 along the circumference. On the axial section of the rotating cylinder II92, the limiting ring II94 and the side wall of the rotating cylinder II92 are in an inverted L shape; the outer diameter of the limiting ring I93 is greater than the inner diameter of the limiting ring II94; When the cylinder II92 is sleeved on the outside of the cylinder I91, the cylinder II92 is restricted from sliding downward along the axis of the cylinder I91 through the interlocking of t...

Abstract

The invention discloses a transformer room air-cooling component comprising a draught fan and a bracket component for fixing the draught fan. The top of a cantilever of the bracket component is detachably fixed to the top of a transformer room. A plurality of guide tubes are distributed adjacent to each other along the circumferential direction of the cantilever so as to form a round tube structure. The tops of the plurality of guide tubes are welding by a ring plate I, and the bottoms of the plurality of guide tubes are welded by a ring plate II. The bottom of the cantilever passes through the ring plate I and then extends into the round tube structure. The round tube structure is fixed to the side wall of the cantilever through the ring plate I. The bottom of the round tube structure isconnected to the top of a fixed box through the ring plate II. The two axial ends of each guide tube are opened, and the interior of the fixed box communicates with the bottom openings of the guide tubes. The draught fan is installed in the fixed box. The air-cooling component provided by the invention helps to change a temperature difference between the radiator of a transformer and the surrounding environment, accelerates the circulation of the transformer oil between the interior of the transformer and cooling fins, timely dissipates the heat in the transformer to the outside through the cooling fins, and is simple in structure and flexible to operate.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an air cooling assembly for a transformer chamber. Background technique [0002] In the power grid system, a substation refers to a place in the power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation, whose function is to boost the electric energy generated by the generator and feed it to the high-voltage grid. At present, more and more natural air-cooled designs are adopted for heat dissipation of oil-immersed transformers in substations. When transformers using this natural air-cooled heat dissipation method encounter high ambient temperature and heavy loads, the radiator of the transformer and the transformer chamber The ambient temperature difference is small, the heat transfer efficiency is low, and the heat dissipation capacity of the radiator is reduced. Th...
