Abstract

Die Erfindung betrifft einen Transformatorkern (70) für einen Leistungstransformator, welcher wenigstens zwei parallel und zumindest annährend kongruent benachbart zueinander angeordnete Transformatorkernscheiben (10, 52, 72, 102, 104, 106) mit einem zumindest ähnlichen Grundriss aufweist. In dem Grundriss ist wenigstens jeweils eine Durchgangsöffnung (12, 14, 54, 56) vorgesehen. Die Transformatorkernscheiben (10, 52, 72, 102, 104, 106) bestehen zumindest überwiegend aus einem amorphen ferromagnetischen Material. Zwischen den Transformatorkernscheiben (10, 52, 72, 102, 104, 106) ist wenigstens ein Kühlkanal (64, 88, 90, 92, 94, 96, 112, 114) angeordnet. Die Erfindung betrifft auch einen Leistungstransformator mit einem derartigen Transformatorkern.
