Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more particularly to an open-close type forced heat dissipation transformer. Background Art

[0002] A power transformer is a static electrical device that is used to convert a certain value of AC voltage (current) into another or several different values ​​of voltage (current) with the same frequency. A static device with two or more windings, in order to transmit electrical energy, converts the AC voltage and current of one system into the voltage and current of another system at the same frequency through electromagnetic induction, usually with different values ​​of current and voltage.

[0003] With the development of society and the increasing popularity of electricity, the importance of transformers as important electrical equipment is self-evident. Especially when people's demand for electricity is also increasing, the power of transformers is also increasing. The problem of high heat generation is becoming increasingly prominent, especially in the peak of electricity consumption in summer. When the transformer generates a lot of heat and cannot be discharged in time, it often causes damage to the transformer or even explosion, leading to serious safety accidents.

[0004] To this end, we propose an open-close forced heat escape transformer to effectively solve some problems existing in the prior art. Summary of the invention

After the forced heat dissipation wings are fully unfolded, the electric telescopic rod is controlled to connect the long gear at the other end, and the spiral wings with opposite rotation directions are cooperated to make the forced heat dissipation wings shrink into the reserved groove, squeeze out the heat inside the reserved groove, and further accelerate the heat dissipation rate.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) This solution uses an electric telescopic rod to push the side gear at one end to connect with the long gear, and uses wind force to drive the rotating rod to drive the asynchronous rotating shaft to rotate, so that the rotating shaft can unfold the fixed fan ribs and the heat storage fan ribs and extend them out of the reserved groove, effectively increasing the heat dissipation area and improving the heat dissipation efficiency. After the forced heat dissipation wing is fully unfolded, the electric telescopic rod is controlled to connect the long gear at the other end, and the spiral wing with the opposite rotation direction is used to make the forced heat dissipation wing shrink into the reserved groove, squeeze out the heat inside the reserved groove, and further accelerate the heat dissipation rate. This is repeated, and cold air is continuously forced to be introduced to squeeze out hot air, which effectively improves the temperature control of the transformer and improves the normal operation performance of the transformer in a high temperature environment.

[0022] (2) In the present scheme, a liquid storage cavity is provided inside the heat storage fan rib, and the liquid storage cavity is filled with a high-expansion liquid. The expansion capsule is connected to the liquid storage cavity. When there is no wind outside, the high-expansion liquid is used to absorb the heat of the transformer, thereby effectively reducing the temperature of the transformer. At the same time, the heat expansion of the transformer is utilized to enter the expansion capsule to expand its volume, and the heat storage fan ribs are unfolded in turn to increase the heat dissipation area, thereby quickly dissipating heat, improving the protection of the transformer, and extending its service life.

[0023] (3) The expansion capsule in this scheme is made of transparent material, and a large number of high-temperature color-changing particles are mixed in the high-expansion liquid. The outer wall of the expansion capsule is equidistantly provided with multiple heat dissipation stripes extending along the direction of the expansion capsule. When the transformer is at high temperature, the high-temperature color-changing particles emit obvious warning colors and cooperate with the expansion capsule to spread the warning colors to a wider range, effectively attracting the attention of surrounding personnel and avoiding burns caused by accidentally touching the transformer. At the same time, multiple heat dissipation stripes can increase the heat dissipation area and accelerate the heat dissipation rate.

[0024] (4) In the present invention, a plurality of reflective sheets are attached to the outer wall of the spiral wing, a bird-repelling disc is provided at the upper end of the rotating rod, a material storage cavity is provided inside the bird-repelling disc, a tiny hole connected to the material storage cavity is provided at the lower end of the bird-repelling disc, and the material storage cavity is filled with bird-repelling powder. The spiral wing rotates to drive the bird-repelling disc to release the bird-repelling powder therein, thereby driving away the surrounding birds, effectively preventing the birds from landing on the transformer and causing discharge or even short circuit. The use of reflective sheets can further improve the bird-repelling effect.

[0025] (5) The fixed angles in this scheme are arranged radially at the corners of the main body, and the ends of the fixed angles are wrapped with an insulating layer. The radially arranged fixed angles can reduce the situation of air breakdown discharge and improve safety. Wrapping the ends with an insulating layer can effectively avoid the probability of tip discharge, further improving safety.

[0026] (6) In this solution, a plurality of arc-shaped heat dissipation pipes are equidistantly arranged at both ends of the main body. The arc-shaped heat dissipation pipes are connected to the interior of the main body. The transformer oil inside the main body is circulated through the arc-shaped heat dissipation pipes, so that the temperature inside the main body is more balanced, thereby improving the safety of the transformer.
