Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer capable of stably adjusting output voltage. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage.

[0003] In the power equipment industry, transformers are crucial current changing devices used to control current and voltage. In our daily lives, household electricity consumption often requires the use of power transformers to control the current output value in order to meet the rated current requirements. However, during the long-term working process of the transformer, the temperature inside the box will continue to rise due to its own electromagnetic induction effect, and traditionally, transformers do not have too many heat dissipation functions. Therefore, the number of times the transformer is used to adjust the voltage through the tap changer every day is limited. In certain cases, multiple transformers need to be used in rotation to solve this problem, resulting in low voltage regulation efficiency.

[0004] Therefore, we provide a transformer that can stably regulate the output voltage. Utility Model Content
