Description

Technical field:

[0001] The utility model relates to a transformer, in particular to a high-efficiency transformer, belonging to the technical field of transformers. Background technology:

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. In the power system, transformers are basic equipment for power transmission and distribution, and are widely used in industries, agriculture, transportation, urban communities and other fields. For example, power transformers are used for the transmission and distribution of electric energy, rectifier transformers are used in power supply circuits that rectify AC power into DC power, and special transformers such as voltage regulating transformers and pulse transformers are used to adjust the output voltage and generate pulse signals respectively.

[0003] When the transformer is in use, the internal electrical components will generate a lot of heat when working. This part of the heat is dissipated through the heat dissipation fins set on the transformer shell to maintain the internal ambient temperature. However, when the external ambient temperature is high, the heat dissipation speed of the transformer will gradually decrease as the ambient temperature rises, resulting in the heat cannot be dissipated in time. The electrical components operate in a high temperature environment, affecting the efficiency of the transformer. Therefore, a high-efficiency transformer is proposed. Utility model content:
