Description

Technical Field

[0001] The utility model relates to the field of iron core press-fitting equipment, in particular to a winding iron core press-fitting device. Background Art

[0002] A voltage transformer is an instrument used to transform voltage. A high voltage transformer is a transformer in a power system that converts high voltage into low voltage or high current into low current for measurement, protection, and use.
