  • Patent number: 8310330
    Abstract: A dry-type transformer includes at least one high-voltage winding and one low-voltage winding. The windings are operatively connected to one another by an electromagnetic field, and each winding is constructed from winding conductors, wherein the high-voltage winding and the low-voltage winding have a defined distance from one another, and spacers are arranged between the windings and maintain the defined distance.

  • Publication number: 20110273256
    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.
