Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof transformers, in particular to an explosion-proof transformer. Background Art

[0002] Explosion-proof transformers are electrical equipment with explosion-proof functions, usually used in places working in flammable and explosive environments. They have the ability to prevent sparks or arcs from occurring in electrical equipment, thereby causing explosions. Explosion-proof transformers use special designs and materials to effectively prevent fires and explosions, and ensure the safety of personnel and equipment.

[0003] After searching, a Chinese patent discloses an oil-immersed transformer, and its authorization announcement number is (CN211719402U), which includes an oil-immersed transformer and a protective shell. The oil-immersed transformer is sleeved inside the protective shell. A pressure relief valve is installed on the end face of the oil-immersed transformer. Front support columns are arranged at the four front corners of the oil-immersed transformer, and left support columns are equidistantly arranged at the center of the left wall of the oil-immersed transformer.

[0004] This patent achieves the effect of rapid heat dissipation by increasing the contact area between the oil-immersed transformer and the cooling water, and the front support column, the left support column, the bottom support column and the heat dissipation fins are all made of aluminum to dissipate heat layer by layer, thereby solving the problem of low heat dissipation efficiency in the authorized patent, where the cold water circulation pipeline is used around the body of the oil-immersed transformer, so that only the surface of the oil-immersed transformer can be partially dissipated. However, in actual use, the shell is dissipated by circulating water contacting the surface of the transformer shell, so that the transformer oil in the transformer shell still has a phenomenon of lower temperature near the shell and higher temperature away from the shell. This situation limits the heat dissipation effect of the transformer oil on the winding group, so that the transformer oil around the winding group still has the risk of explosion. At the same time, the overall structure of the existing transformer is large and inconvenient to move and transport. To solve these problems, we propose an explosion-proof transformer.

[0022] When transporting the transformer, the lifting slot 13 and the forklift slot 14 are used in conjunction with external mobile transportation equipment to transport the transformer as a whole, which simplifies the movement and transportation of the transformer and improves the utilization efficiency of the transformer. During use, the heat emitted by the transformer body 6 is directly conducted to the heat dissipating plate 8 through the heat conduction structure, and then the heat dissipation work is completed under the action of the heat dissipating fins 9 on one side of the heat dissipating plate 8, thereby avoiding the situation where the temperature change of the transformer body affects the heat of the transformer oil and reducing the risk of explosion.
