Description

Technical Field

[0001] The invention relates to the technical field of power transformers, and in particular to a hybrid heat dissipation type power 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. When AC is passed through the primary winding, an alternating magnetic flux is generated. The alternating magnetic flux induces an AC electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns;

[0003] The power transformer is provided with a heat sink on the outside to achieve a heat dissipation effect on the power transformer. However, when the power transformer is in use, the heat sink is very slow in dissipating the heat inside the power transformer, which causes heat to accumulate in the power transformer, causing the parts inside the power transformer to be affected by the high temperature, which is easy to cause damage to the parts and reduce the service life of the power transformer.
