Three=phase transformer arrangement

摘要

The three-phase transformer has a ring-shaped core (1) comprised of a stack of magnetisable laminations (2) and including three radial spokes (3) evenly angularly spaced apart from one another, and with a primary coil (4) and a secondary coil (5) wound around each spoke (3). An outer lying ring (6) made of a magnetisable material is secured to the ends of the radial spokes opposite to the ends supporting the ring-shaped core (1).
