Abstract (en)
The invention relates to a medium voltage circuit breaker for subsea applications, with a vacuum interrupter arranged inside a pressure housing, which is tight against environmental high pressure, and with a drive, in order to move a movable contact of the vacuum interrupter, relatively to a fixed contact of the vacuum interrupter, according to the preamble of claim 1. In order to enhance the design of the vacuum circuit breaker arrangement in that way, that the arrangement is functionally safe under the aforesaid environment conditions, the invention is, that the magnetic drive is separated in two parts,wherein the first part with a mechanical link to the moved contact is arranged inside of the pole housing and a second part, consisting the coil or the coils is, or are arranged outside of the pole housing, and that the coil or the coils to control the magnetic drive, are as well arranged outside of the housing.
