Publication number: 20230253768Abstract: The invention relates to enclosures (1) for gas-insulated medium-voltage or high voltage apparatuses. A connection portion (4) between a first end (20) of the first enclosure tube (2) and a mating machined second end (30) of the second enclosure tube (3) has a gas-escape path (L) running from the inside (6) to the outside (7) of the enclosure tubes (2, 3). According to the invention, the gas-escape path (L1) is shaped to have a first segment (L1) running along an at least partially axial direction of the enclosure (1) and being equipped with least one sealing ring (5; 5a, 5b). In addition, a slim ring-like snap-on bracket (9) can be used. The direct machining of the mating enclosure ends (20, 30) allows to omit conventional flanges. The partially axial orientation of the gas-escape path (L) allows to provide plural sealing rings (5; 5a, 5b) in series in the gas-escape path (L).Type: ApplicationFiled: July 21, 2020Publication date: August 10, 2023Applicant: Hivoduct AGInventor: Walter Holaus
