Abstract

The invention relates to a high-efficiency heat dissipation transformer, belonging to the technical field of transformers. The invention comprises a transformer housing, A window orientation device for detecting the highest heat dissipation efficiency is arranged above the transformer cabinet. the winding is arranged in the transformer box, Iron core, motor I, Motor II1, Control unit, the transformer box is provided with a louver vent in four planes perpendicular to the ground, The shutter grille blade of the shutter vent is fixed on the rotating shaft of the shutter, the rotating shafts in four directions are controlled to rotate by the motor I and the motor II 1, respectively, and the side wall of the transformer box is provided with a control device, which is respectively connected withthe window orientation device, the motor I and the motor II 1 for detecting the highest heat dissipation efficiency. The invention solves the problem that the heat dissipation performance of the existing transformer is affected by the hot air return phenomenon, which leads to poor heat dissipation effect, improves the protection effect of the transformer, and prolongs the service life of the transformer.

Description

technical field [0001] The invention relates to a high-efficiency heat dissipation transformer, which belongs to the technical field of transformers. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. At present, the heat dissipation of oil-based transformers mainly includes oil-based self-cooling, oil-immersed air-cooled, and forced oil circulation. Dry-type transformers mainly rely on air convection cooling, and the temperature of the transformer generally rises quickly. If the temperature of the transformer is too high, it will cause The transformer is burnt due to overheating, and there is still a lot of room for improvement in the existing he...

Problems solved by technology

At present, the heat dissipation of oil-based transformers mainly includes oil-based self-cooling, oil-immersed air-cooled, and forced oil circulation. Dry-type transformers mainly rely on air convection cooling, and the temperature of the transformer generally rises quickly. If the temperature of the transformer is too high, it will cause The transformer is overheated and burnt down. There is still a lot of room for improvement in the existing transformer heat dissipation method, especially for the transformer in the protection cabinet that still uses self-cooling heat dissipation, and the heat dissipation effect is not ideal.
