Abstract (en)
The invention relates to a Vacuum interrupter for low-, medium-, or high-voltage use, for high environmental pressure application, with at least one moving contact and one fixed contact in an insulting ceramic housing. In order to reduce the needed number of parts in the case of a pressure tight vacuum interrupter or switchgear installation in high pressure environment like in subsea application, the invention is, that the ceramic housing (4) of the vacuum interrupter itself is high pressure tight, in the range of vacuum inside the ceramic housing, and up to 500 Bar outside of ceramic housing.
