  • Patent number: 11342095
    Abstract: An insulation material for a DC electrical component. The insulation material includes a thermoset or thermoplastic matrix and a functional filler component. The functional filler component has a non-linear DC conductivity depending on an applied electrical field strength. At least in a temperature range of 0° C. to 120° C., the functional filler component has a bandgap in the range of 2 to 5 eV, and optionally in the range of 2 to 4 eV. Furthermore, a method for producing an insulation material, a use of an insulation material for a high voltage DC electrical component, a DC electrical component comprising the insulation material and the use of a DC electrical component comprising the insulation material in a high voltage DC gas insulated device are suggested.

  • Patent number: 9172221
    Abstract: A converter building including at least one room having a solid room wall enclosing an interior space and an electrical active part contained in the interior space, the room wall having at least one opening, which is designed such that it allows a human to enter the interior space. The opening is sealable, the room wall encloses the interior space in a gas-tight manner when the opening is sealed, and the interior space contains a dielectric insulation medium including a dielectric insulation component other than air.

  • Publication number: 20130021709
    Abstract: A conductor arrangement is provided for reducing very fast transients in high voltage applications. The conductor arrangement includes a conductor element having a main conducting orientation, and a conductive annular shell element coaxial to the conductor element, thus forming an annular cavity around the conductor element. The annular shell element in the main conducting orientation includes a first end portion and a second end portion. The first end portion is conductively connected to the conductor element. The second end portion includes an annular collar which is substantially coaxial to the conductor element, thus together with the conductor element forming a coaxial capacitor which has a solid material filling. The capacitor includes a surge arrester which may serve as an energy conversion portion.
