INSULATION SYSTEM AND INSULATION METHOD FOR TRANSFORMER

摘要

PROBLEM TO BE SOLVED: To provide an insulation system and an insulation method for a transformer containing a magnetic core.

SOLUTION: A transformer (10) contains a magnetic core (14) that includes multiple laminate stacks having at least one opening. The transformer (10) also contains a winding (30) comprising a conductive material that is provided around the magnetic core (14) through the at least one opening (20) and is surrounded by an insulating layer (54) having a dielectric constant that varies as a function of voltage.
