  • Arrangement and method for switching high currents in high-, medium- and/or low-voltage engineering
    Patent number: 11417479
    Abstract: An arrangement and a method for switching high currents include at least one vacuum switching path and at least one rated-current contact switching path. The at least two switching paths are electrically connected in parallel. One current path for a rated current is routed over at least one rated-current contact of said rated-current contact switching path, and a parallel current path for a short-circuit current is routed over at least one contact of a vacuum tube of the vacuum switching path.
    Type: Grant

  • Filter bag
    Patent number: 6743272
    Abstract: The invention relates to a filter bag for holding filtering material located inside a gas-installed housing of the electrical installation. The filter bag is produced from a fabric that is resistant to high temperatures, which eliminates the need for holding devices protecting the filter bag from hot switching gases to be provided inside the compressed gas housing.

  • Filter bag
    Publication number: 20030172631
    Abstract: The invention relates to a filter bag (11) for holding filtering material located inside a gas-insulated housing of an electrical installation. Said filter bag is produced from a fabric that is resistant to high temperatures, which eliminates the need for holding devices protecting the filter bag from hot switching gases to be provided inside the compressed gas housing.
