Abstract: A grounding switch is comprised of a structural frame, at least one first contact, at least one second contact, at least one spacer, and a geared drive assembly. The opening and closing of the grounding switch is controlled by the geared drive assembly. The geared drive assembly is operable to rotate the at least one second contact around the axis of a connecting rod to move the at least one second contact into and out of contact with the at least one first contact. The closing of the grounding switch first and second contacts serve to connect a transformer or other electrical device to ground potential.

Abstract: A dry-type network transformer has a core and coil windings insulated by a combustion-inhibiting gas. The combustion-inhibiting gas, core and coil windings are disposed within a hermetically-sealed enclosure. The combustion-inhibiting gas is air, an inert gas or a mixture of gases. The dry-type network transformer may be connected to a network protector. The network protector is further connected to a secondary network. The network protector prevents power from flowing from a secondary network to the primary side of the transformer. The dry-type network transformer is installed in a vault that is underground or at ground level. The dry- type network transformer may be suspended near the ceiling of the vault or installed at the base of the vault.

Abstract: The invention relates to a transformer core (10, 20, 102) for a power transformer (100). Said transformer core (10, 20, 102) extends about an imaginary center axis (14, 35, 104) in the form of a closed toroidal structure. The transformer core (10, 20, 102) is mainly constituted of a plurality of adjacent layers of sheet metal (17, 48-1, 48-2, 48-3, 48-4, 48-5). It has a toroidal structure having a polygonal horizontal section with three or five or more corners and a corresponding number of transformer legs, said structure extending about the center axis (14, 35, 104).

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.
