Abstract
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.
Claims19
A transformer of dry design having a core including an amorphous material that is sensitive to mechanical loads, comprising:
- 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
- at least one holding apparatus, wherein the holding apparatus is used to fix the at least one primary winding and secondary winding in the each case, and the holding apparatus acts on each end face of the at least one winding former.
A method for production of a transformer having a winding strip core including an amorphous material that is 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 secondary winding, and at least one holding apparatus, the method comprising:
- producing a strip material from amorphous material;
- winding an annular core with the same cross section in each case from the amorphous strip material;
- placing two rectangular individual cores with their longitudinal limbs against one another;
- winding the strip material around the individual cores in a winding plane of the individual cores, such that the winding plane has three longitudinal limbs with a same cross section;
- providing outer limbs of the transformer core with at least one of the electrical lower-layer winding or the electrical upper-layer winding;
- and
- connecting the electrical windings.
