Problems solved by technology

For small-capacity transformers, smooth oil tank surface is enough to cool the oil; for medium-capacity transformers, the surface of the oil tank should be wrinkled to increase the heat dissipation surface, or a fin or flat tube radiator should be installed to make the oil circulate in the radiator A radiation radiator should be added on the surface of the large-capacity transformer oi

Embodiment 1

[0043] see Figure 1-2 , a self-ventilating heat dissipation oil-immersed transformer, including a transformer body 1, a plurality of evenly distributed heat dissipation fins 2 are connected to the outer end of the transformer body 1, and the heat dissipation fins 2 and the transformer body 1 are integrally formed, The heat dissipation fins 2 are provided with a plurality of evenly distributed ventilation and heat dissipation holes 3 .

[0044] The volume of a pair of sub-inflatable holes 32 is greater than the volume of the main vent hole 31, the maximum extension distance of the elastic backguy 7 is consistent with the length of the sub-inflatable holes 32, and the volume of the sub-inflatable holes 32 will ensure that after the migration of the magnetic transfer balloon 6 The gas supplemented by the outside should be more than the original gas in the main ventilation hole 31, so as to fully ensure the heat exchange effect, and the elastic stay wire 7 should ensure that the mag

Abstract

The invention discloses a self-ventilation heat dissipation type oil-immersed transformer, and belongs to the field of transformer equipment. Innovative presetting of ventilation heat dissipation holes in heat dissipation fins can be realized, the migration action of magnetic migration air exchange balls is triggered through the magnetic action after heat is sensed, the magnetic migration air exchange balls are forced to migrate in the ventilation heat dissipation holes and push air to advance towards the interior of a transformer body, air blowing films are inflated and expanded to increase the contact area with transformer oil, the heat conduction effect of the transformer oil can be improved, and meanwhile the contact area can be increased to improve the heat exchange effect. In addition, air in the ventilation heat dissipation holes enters the air blowing films and then is supplemented by external cold air, after the magnetic migration air exchange balls are cooled, the magnetic migration air exchange balls are reset under the elastic action of elastic pull wires, the migration action is repeated, the contact area of the heat dissipation fins and the external air can be increased, and meanwhile the heat exchange effect is improved in an active ventilation mode, and therefore, the heat dissipation performance of the heat dissipation fins is greatly improved.
