Abstract
A wound transformer core is provided with at least one core loop made of a magnetic material. The transformer core includes multiple thin amorphous band-like iron sheets which are concentrically stacked around at least one center axis. A lower yoke section, an upper yoke section, and at least two limb sections are formed. The transformer core includes a modular plate-like support structure which is affixed upright to the center axis on both face sides of the lower yoke section and on both face sides of each limb section such that neighbored iron sheets are affixed together at their outer edge. The modular plate-like support structure includes, for each face side of the corresponding core sections, at least two plate-like modules, which are each connected to each other by a first or second plug-in connection.
