    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 method for producing a disk winding (9) comprising at least three disks (1, 2, 3) which are arranged adjacent to each other. An intermediate isolation (A, B) is produced at the same time as the winding between respectively two disks (1, 2, 3) during the winding process, a connection conductor (7, 7A, 7B) extends from the end of one of the disks to the beginning of the other disk in the form of a diagonal inside the intermediate isolation (A, B) and the intermediate isolation is divided into two partial areas, that is, a first intermediate isolation area (A1, B1) having a triangular cross-section which is formed below said diagonal and a second intermediate isolation area (A2, B2) having an inversed triangular cross-section which is formed above said diagonal, an isolation is placed in the second intermediate isolation area (A2) to the left of the disk (2) and an isolation is placed in the first intermediate isolation area (B1) to the right of the disk (2) during a disk winding which unwinds from left to right at the same time as the winding of the disk (2), and an isolation is placed in the second intermediate isolation area (A2) to the right of the disk (2) and an isolation is placed in the first intermediate isolation area (B1) to the left of the disk (2) during a disk winding which unwinds from right to left as the same time as the winding of the disk (2).

    Abstract: The invention relates to a transformer of dry construction having a core made of amorphous material, which is sensitive to mechanical stresses, having at least one winding assembly surrounding the core and formed from at least one primary winding and secondary winding in each case, and having at least one holding device, and also to a method for the production thereof, whereby the holding device serves to fix the at least one primary winding and secondary winding in each case and, to this end, loads the at least one winding assembly, in each case at the ends thereof.

    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.

    IPC: H01F27/30

    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).

    IPC: H01F41/00

    Abstract: A method is disclosed for producing a multi-layer transformer winding. During or after the winding of a conductor layer around a winding body, a layer of electrically insulating material can be applied on the radially outer surface thereof. A dry fiber composite can be used as the insulating material. The fiber composite can be bonded into an insulating layer by heating the transformer winding to a composite temperature.
