Power transformer with amorphous core

摘要

A transformer of dry design is disclosed having a core composed of amorphous material, which is sensitive to mechanical loads, having at least one winding former which surrounds the core and is in each case formed from at least one primary winding and secondary winding, and having at least one holding apparatus. A method for transformer production is also disclosed, wherein the holding apparatus is used to fix the at least one primary winding and secondary winding in each case and for this purpose it acts on each of the end faces of the at least one winding former.

1. A transformer of dry design comprising:
a core in the form of a winding ribbon core composed of an amorphous material, the core being sensitive to mechanical loads; at least one winding former which surrounds the core and is in each case formed from at least one primary winding and one secondary winding; and at least one holding apparatus configured to fix the at least one primary winding and one secondary winding, the at least one holding apparatus being formed from at least two clamping elements which are operatively connected to one another and act on each end face of the at least one winding former, wherein the core composed of amorphous material is held suspended by the at least one holding apparatus, and wherein the at least one winding former is held independently of the core by the at least one holding apparatus such that mechanical loads applied to at least one of the holding apparatus and the at least one winding former are not subjected to the winding ribbon core.
