Air-cooling dry-type power transformer

Abstract

The invention discloses an air-cooling dry-type power transformer. The transformer structurally comprises a display lamp, buttons, a display screen, a controller, a wire, a top plate, transformer bodies, a mounting box, heat dissipation devices, a base and a fixing rack, the display lamp and the buttons are located in a same center line, and the display screen and the button are located in a sameplane; the display screen is embedded in the outer surface of the controller, the buttons are attached to the outer surface of the controller, the wire and the controller are of an integrated structure, and the top plate is welded to the top of the mounting box. According to the air-cooling dry-type power transformer, the heat dissipation devices are structurally arranged on the transformer and connected with the outer surface of the transformer, coils of the heat dissipation devices start to run under the effect of electric power, and then bearings start to rotate and run, so that rotation rods also start to rotate, fan blades can start to rotate under the acting force generated by the rotation of the rotation rods, and heat generated in running of the transformer is discharged outward from a dust prevention net; the heat dissipation effect is achieved, the heat dissipation performance is good, and the service life of the transformer is prolonged.

Description

technical field [0001] The invention is an air-cooled dry-type power transformer, which belongs to the field of air-cooled dry-type power transformers. Background technique [0002] A transformer is a static electrical device used to transform AC voltage and current to transmit AC power. It realizes power transfer based on the principle of electromagnetic induction. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers according to their uses.
