Heat dissipation type transformer

Abstract

The invention discloses a heat dissipation type transformer, which comprises a transformer cabinet body, wherein three groups of parallel windings are arranged in the transformer cabinet body; a heatdissipating device is disposed outside the winding; the heat dissipating device comprises a front heat dissipating structure on the front side of the winding and a rear air pumping structure on the back side of the winding; the front heat dissipating structure comprises a front fan; the front fan comprises a fixed frame and a rotating shaft rotatably fixed to the fixed frame; the rotating shaft isprovided with three sets of blades having axial through holes; the blade is provided with a vent hole communicating with the through hole and a nozzle communicating with the vent hole; the nozzle islocated on the outer end surface of the blade, and the nozzles of the three sets of blades are used for ejecting gas so that the blades rotate clockwise; the through hole communicates with a gas transmission pipe; the gas transmission pipe communicates with a coil; the coil communicates with an intake pipe; the intake pipe is provided with an air pump; and the end of the intake pipe communicates with the external gas. The heat dissipation type transformer in the invention is provided with a front heat dissipation structure located on the front side of the winding and a rear air pumping structure on the back side of the winding respectively, thereby improving the heat dissipation effect.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a heat dissipation transformer. Background technique [0002] In the prior art, the heat dissipation method of the transformer is generally to provide heat dissipation holes on the cabinet body of the transformer, so as to dissipate heat through natural wind. As a result, the transformer is dissipated through the air duct formed between the air inlet and the exhaust port. However, due to the excessive distance between the transformer body and the inner wall of the transformer cabinet, part of the air volume is basically lost from the outside far away from the transformer body, which cannot be achieved. The proper cooling effect is achieved, resulting in low heat dissipation efficiency of the transformer, which affects the working efficiency of the transformer, so that the transformer can only operate at full load within a certain ambient temperature range.
