Heat dissipation mounting structure of transformer

Abstract

The invention discloses a heat dissipation mounting structure of a transformer. The heat dissipation mounting structure comprises a first protective cover and a second protective cover of the same structure; a mounting cavity for mounting the transformer is formed in each of the first protective cover and the second protective cover separately; through holes connected with the corresponding mounting cavities are formed in the side edges of the first protective cover and the second protective cover; protection boxes are mounted on the side edges of the first protective cover and the second protective cover respectively; a heat dissipation hollow cavity is formed in each protection box; an opening through groove is formed in the bottom surface of each heat dissipation hollow cavity; and a drying box is inserted and connected in each protection box. The protection boxes disclosed in the invention are in contact with the external environment; when external air flowing speed is higher thanthat in the mounting cavities, the intensity of pressure in the mounting cavities is increased, so that the heat in the mounting cavities is discharged via through holes to the heat dissipation hollowcavities, thereby facilitating heat dissipation of the transformer in the mounting cavities; and when the external air humidity is relatively high, damage to the transformer in the mounting cavitiesby the external moisture air can be prevented effectively by virtue of the drying agent in the drying boxes.

Description

technical field [0001] The invention relates to the technical field of a heat dissipation installation structure of a transformer, in particular to a heat dissipation installation structure of a transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transf...

AI Technical Summary

Problems solved by technology

[0005] At present, heat sinks are installed on oil-immersed transformers. It improves the heat dissipation effect by increasing the heat dissipation area, and the cooling of the heat sink is realized by exchanging heat with the outside world. Obviously, the heat sink of the transformer exchanges heat with the air. The speed is too slow, and as the ambient temperature rises, the switching speed will become slower and slower, which will affect the heat dissipation effect of the transformer (overload capacity)
