Abstract (en)
The invention is related to a high-voltage-transformer (10) comprising at least one transformer-core (12, 30) wound from an amorphous band-like material (32, 52) around at least one inner hollow (14, 16, 44, 46), wherein two opposed laminated front sides are formed by the edges of the wound band-like material (32, 52) and wherein at least two opposed limb areas (34, 36, 38) and an upper (40, 98) and lower (42, 64) yoke area are formed. At least one hollow-cylindrical transformer coil (18, 20, 22) is arranged around a limb area (34, 36, 38) of the at least one transformer-core (12, 30). Cooling means (54, 58, 72, 94, 96) are connected with at least a section of at least one of the laminated front sides.
