Embodiment 1

[0036] This embodiment provides an air-cooled assembly for a transformer room, including a fan 7 and a bracket assembly for fixing the fan 7, such as figure 2 with 3 As shown, the bracket assembly includes a cantilever 1, a fixed box 2 and a plurality of draft tubes 3. The top end of the cantilever 1 is used to be detachably fixed on the top of the transformer chamber. The cantilever 1 adopts a cylindrical structure. 1 Axial vertical mounting plate, the mounting plate is fixed on the top of the transformer room by bolts; each draft tube 3 adopts a round tube, and multiple draft tubes 3 are arranged adjacent to each other along the circumference of the cantilever 1 so that multiple draft 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 the multiple draft tubes 1 are welded and fixed by t...

Embodiment 2

[0038] It is further improved on the basis of embodiment 1. The inner wall of the ring plate I4 extends outward along the cantilever 1 to form a connecting sleeve 8. The connecting sleeve 8 is provided with a through hole. Into the cantilever 1 fixed on the side wall. 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 to select a bolt.

[0039] The ring plate II5 is connected to the fixed box 2 through a rotating joint 9; the rotating joint 9 includes a rotating drum I91 and a rotating drum II92. One end of the rotating drum I91 is fixed on the ring plate II5, and the other end extends into one end of the rotating drum II92. The other end of the II92 is connected to the top of the fixed box 2; at the socketed part of the drum I91 and the drum II92, the outer wall of the drum I91 and the inner wall of the drum II92 a...

Embodiment 3

[0042] It is further improved on the basis of embodiment 2, and the difference lies in the connection mode of the drum I91 and the drum II92 and the structure of the fixed box 2. The outer side wall of the bottom end of the rotating drum I91 is provided with a limiting ring I93 along the circumferential direction. On the axial section of the rotating drum I91, the limiting ring I93 and the side wall of the rotating drum I91 are L-shaped; the inner side of the top of the rotating drum II92 The wall is provided with a limit ring II94 along the circumferential direction. On the axial section of the drum II92, the limit ring II94 and the side wall of the drum II92 are in an inverted L shape; the outer diameter of the limit ring I93 is larger than the inner diameter of the limit ring II94; When the drum II92 is sleeved outside the drum I91, the centrally symmetric L-shaped structure and the inverted L-shaped structure are mutually clamped to restrict the drum II92 from sliding down 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-cooled assembly for a transformer room. Background technique [0002] In the power grid system, a substation refers to a place in the power system that transforms voltage and current, receives electrical energy and distributes electrical 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 power grid. At present, more and more oil-immersed transformers in substations adopt natural air-cooling design for heat dissipation. When the natural air-cooled heat dissipation method encounters high ambient temperature and heavy load, the radiator of the transformer and the transformer room The ambient temperature difference is small, the heat transfer efficiency is low, and the heat dissipation capacity of the heat exchanger is reduced. Therefore, the heat dissipa...
