Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and more specifically, particularly relates to an oil-immersed transformer. Background Art

[0002] Oil-immersed transformer is a common type of power transformer, and its main feature is that it is filled with insulating oil. This oil is usually mineral oil or silicone oil, which is used to provide insulation and cooling. Oil-immersed transformers usually consist of an iron core and windings, which are wrapped in insulating oil. The iron core is made of silicon steel sheets to concentrate the magnetic field and reduce iron losses.

[0003] Based on the above, the inventors have found the following problems: when current transformers are in use, most are installed between two utility poles. A number of heat sinks are installed on the surface of the transformer, and the surface of the heat sink will dissipate a large amount of heat. Therefore, the heat sink on the side close to the utility pole will dissipate a large amount of heat to the utility pole, which may accelerate the cracking of the utility pole, thereby creating a safety hazard.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an oil-immersed transformer is provided to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an oil-immersed transformer to solve the problem that the existing transformer may accelerate the cracking of the electric pole and cause potential safety hazards.

[0006] The purpose and effect of the oil-immersed transformer of the utility model are achieved by the following specific technical means:

[0007] An oil-immersed transformer comprises a transformer body, a plurality of heat sinks are installed around the surface of the transformer body, a mounting box is installed on the surface of the transformer body, a chamber is provided in the mounting box, a plurality of fans are installed in the chamber, and the heat sinks on both sides of the transformer body are arranged horizontally.

[0008] Furthermore, a mounting rod is installed at the bottom of the transformer body.

[0009] Furthermore, a group of slide grooves are opened on both sides of the transformer body, a group of blocks are installed on the surface of the installation box, a group of threaded holes are opened on both sides of the transformer body, a group of connecting plates are installed on the surface of the installation box, and the connecting plates are connected to the transformer body by bolts.

[0010] Furthermore, the slide groove matches the clamping groove, and the threaded hole matches the bolt.

[0011] Furthermore, a grille is installed on the surface of the installation box.

[0012] Furthermore, a through slot is provided at the bottom of the installation box.

[0013] Furthermore, a bird repeller is installed on the top of the transformer body.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model uses an installation box, a chamber and a fan. When the heat sink dissipates heat, the fan is started and blows the heat of the heat sink forward. At the same time, the horizontally arranged heat sink is more convenient to use with the fan. Through the above design, the heat generated by the heat sink close to the utility pole can be blown forward, which avoids the heat generated by the heat sink accelerating the cracking of the utility pole and reduces safety hazards.

[0016] Through the slide groove, the block, the threaded hole, the connecting plate and the bolt, when the fan needs to be repaired, it is only necessary to unscrew the bolt, and then push the installation box to make the block away from the slide groove to remove the installation box. Through the above design, the installation box can be quickly removed, which is convenient for repairing the fan. BRIEF DESCRIPTION OF THE DRAWINGS
