Wound transformer core with support structure

摘要

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.

1. A wound transformer core comprising:
at least one core loop made of a magnetic material; multiple thin amorphous band-like iron sheets which are concentrically wound around at least one center axis to form a lower yoke section, an upper yoke section, and at least two limb sections, the lower yoke section, the upper yoke section and the at least two limb sections each having a first face side and a second face on opposite sides thereof, respectively; and a modular plate-like support structure which is affixed upright to the center axis on both the first and second face sides of the lower yoke section and on both the first and second face sides of each limb section such that neighbored iron sheets are affixed together at their outer edge, wherein the modular plate-like structure includes, for each face side of the lower yoke and limb sections, at least two plate-like modules glued thereon, which are connectable to each other by a plug-in connection.
