Metal-encapsulated switch panel

摘要

An electrical, encapsulated and gas-insulated switch panel is formed from a plurality of closed subspaces. A plurality of these subspaces are combined to form a gas monitoring unit and are connected via special filters having rigidly specified gas permeability. Filters which are in a screw-in cartridge form and consist of sintered metal, which are inserted into the zone of the insulating material bushings which are earthed and are free of fields, are particularly suitable. Using the invention, only one gas space now needs to be monitored and filled, in an advantageous manner, and adequate compartmentalisation of the subspaces in the event of defects is ensured just as well.
