Water drop type mining transformer circulating refrigeration device

Abstract

The invention discloses a water drop type mining transformer circulating refrigeration device, which belongs to the technical field of transformer heat dissipation, and can cool a transformer through heat dissipation liquid when the transformer works normally, and when the temperature of the transformer is too high, a plurality of thermal expansion hemispheres in contact with a heated block are heated to expand. Water in the adsorption sponge is extruded and then flows onto the refrigeration ball, the water cooled by the refrigeration ball continuously drips, the refrigeration effect is achieved, part of steam generated by the heat dissipation liquid is attached to the surfaces of the mesh film and the condensation mechanism due to heat of the transformer, and meanwhile the steam is condensed into large and small water drops after encountering the water drop cone cylinder refrigerated by the refrigeration ball to be dropped back along a guiding thin pipe to achieve a circulating cooling effect. When the temperature of the transformer drops, the thermal expansion hemisphere gradually recovers to the shape, the thermal expansion hemisphere pulls the adsorption sponge to adsorb moisture on the surface of the mesh film, and after water drops stop dropping, the saltpeter powder gradually crystallizes for next use.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of transformers, and more specifically relates to a water drop type mining transformer circulation refrigeration device. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. The transformer is used to convert AC A static electrical device that transmits alternating current energy through voltage and current. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers in terms of their uses: power transformers are necessary equipment for power transmission and distribution, and power user distribution; test transformers can withstand voltage (boost) fo...

Problems solved by technology

[0003] When the existing mining transformer is in operation, the loss of the winding and the iron core will generate a lot of heat. Once it is not dissipated in time, it will cause damage to the winding and other components.

[0004] According to the environmental requirements of mining transformers, in order to avoid the explosion and sparks of the transformer, it is necessary that the transformer is not in direct contact with the atmosphere, so the body needs to be installed inside the shell. However, this sealed environment directly reduces the heat dissipation effect, greatly The service life of the transformer is reduced, so a water drop type mining transformer circulation refrigeration device is proposed
