Amorphous transformer core

摘要

The core (40) has a transformer core disk (42) provided with a set of layers of strip-like amorphous core material and arranged concentrically around at a winding window. A heat dissipating plate (46) i.e. foil, extends into an interior of the core that is fed from the interior to a heat exchange region (50) outside the core for dissipation of heat energy produced inside the core. The heat dissipating plate is arranged in sections between two adjacent layers of the strip-like amorphous core material, and is fed out of a side surface of the transformer core. The heat dissipating plate is made from copper or aluminum. An independent claim is also included for a transformer comprising an electrical winding.
