Abstract: The disclosure relates to a ring-shaped core for a power transformer. The ring-shaped core extends about an imaginary center axis in the form of a closed toroidal structure and is constituted of a plurality of adjacent layers of sheet metal. The ring-shaped core, along the length of the toroidal structure, is constituted of at least three core section modules that can be connected to and detached from each other, the core section modules being interconnected by an overlap of individual sheet layers and/or sheet layer sections. The disclosure also relates to the arrangement of ring-shaped cores having winding modules. The latter can be arranged in a common connecting structure and every ring core having winding modules arranged therein can be separately introduced into the connecting structure and removed therefrom in a non-destructive manner.

Abstract: The invention relates to a ring-shaped core for a power transformer (18), wherein the ring-shaped core extends about an imaginary center axis (70) in the form of a closed toroidal structure and is constituted of a plurality of adjacent layers of sheet metal. The ring-shaped core, along the length of the toroidal structure, is constituted of at least three core section modules (11) that can be connected to and detached from each other, the core section modules being interconnected by an overlap of individual sheet layers and/or sheet layer sections. The invention also relates to the arrangement of ring-shaped cores having winding modules (100). The latter can be arranged in a common connecting structure and every ring core having winding modules (101-103, 111-113, 121 -123) arranged therein can be separately introduced into the connecting structure and removed therefrom in a non-destructive manner.

Abstract: The invention relates to a dry-type transformer comprising at least one high-voltage winding and at least one low-voltage winding which interact by means of an electromagnetic field. Every winding is constituted of winding conductors, the high-voltage winding and the low-voltage winding having a defined distance to each other, spacers (10) being provided between the windings to maintain said distance. The invention further relates to a method for producing the spacers (10).
