  • Patent number: 4031459
    Abstract: An inductive voltage transformer for a high-voltage metal-clad switch-gear installation fully insulated by means of an insulating gas, which includes a pressure vessel flangedly connected to the metallic capsule of the switch-gear installation and has a high-voltage winding constructed as layer winding which is surrounded by the high-voltage electrode; the insulating gas disposed within the pressure vessel thereby forms the high-voltage insulation while the high voltage electrode is drawn axially over the winding end faces of at least a portion of the layer winding; the central portion of the high-voltage electrode surrounding the winding cross section of the layer winding as well as the edge portions thereof axially drawn beyond the layer winding are thereby so curved that the outer surfaces thereof form together with the adjacent cylindrical wall portions of the pressure vessel at least approximately a Rogowski-profile projected on a cylindrical area.
