Technical Field

The utility model relates to a power transformer technical field especially relates to a power transformer.

Background

The transformer is a static electrical equipment for transforming alternating voltage and current to transmit alternating current energy, which realizes the electric energy transmission according to the electromagnetic induction principle, the transformation principle of the transformer is firstly discovered by Faraday, but the practical application is not started until 80S in nineteenth century, in the competition that a power plant should output direct current and alternating current, the transformer can convert the electric energy into a high-voltage low-current form and then convert the high-voltage low-current form back, thereby greatly reducing the loss of the electric energy in the transmission process, leading the economic transmission distance of the electric energy to be farther, the winding of the S series oil-immersed power transformer generally adopts a copper wire wound into an elliptical cylindrical structure, an iron core adopts an approximate elliptical section, a low-voltage winding and a high-voltage winding are wound into a whole and are directly sleeved on the iron core column, thereby forming the core structure of the oil-immersed power transformer, the S series oil-immersed power transformer is mostly elliptical winding at, the winding is soaked in oil, the oil is used as an insulating medium and a cooling medium, the cooling mode is self-cooling, and compared with a dry-type transformer, the dry-type transformer has the defects of low temperature resistance level, poor fireproof performance and difficulty in carrying, but the dry-type transformer is still widely applied due to large capacity, large load, stability, reliability and low price, but the conventional power transformer has the defect of poor heat dissipation effect, so that the power transformer is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that the radiating effect is poor among the prior art, and the power transformer who provides.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a power transformer, includes the transformer main part, the top of transformer main part is equipped with the oil storage bucket, be equipped with a plurality of heating panels on the both sides conch wall of transformer main part, every the heating panel all rotates to be connected in the transformer main part, every all be equipped with the cooling tube on the cooling panel, inside the transformer main part was all stretched into at the both ends of cooling tube, the tip at the both ends of cooling tube all is equipped with the rubber tube, the inside sliding connection of both sides conch wall of transformer main part is equipped with a plurality of push pedals, be equipped with the gear on the cooling panel, be equipped with the rack with gear engaged with on the interior plate face that the upper and lower both ends of push pedal are close to the gear, the inside of transformer main.

Preferably, eight heat dissipation plates are arranged and divided into two groups, and each group is arranged on the transformer main body in a mirror symmetry mode.

Preferably, the transformer main body is a square sealing shell with thick shells on two sides.

Preferably, the gears are arranged on the heat dissipation plate in a vertically mirror-symmetrical manner.

Preferably, the two push plates are arranged on the two side shell walls of the transformer main body in a mirror symmetry mode, and one end of each push plate extends out of the transformer main body and is fixedly connected with the output end of an external electric push rod.

The utility model provides a pair of power transformer, beneficial effect lies in: when the device is used, the electric push rod outside the device is controlled to push the push plate to do reciprocating motion, the gear drives the heat dissipation plate to swing back and forth under the meshing action, a large amount of heat can be generated when the transformer winding works, so that the medium oil inside the transformer winding is heated and expanded, and the heat is transferred from the high-temperature inside to the low-temperature heat dissipation plate and the heat dissipation pipe, the heat dissipation area of the heat dissipation plate is increased, the heat dissipation efficiency is improved, and under the action of the structure of the push plate, the fan-wing action like a bird is realized, the air flow near the main body of the transformer is disturbed to flow, the heat is prevented from accumulating near the main body of the transformer, the heat dissipation efficiency is further accelerated, the heat dissipation pipe is communicated with the medium oil inside the main body of the transformer and can be prevented from leaking, the device has reasonable design and simple, is suitable for popularization.
