Abstract
A medium voltage circuit breaker for the use in high pressure environments has a vacuum interrupter with a fixed contact side and a movable contract side with a movable rod, and a drive in pressure tight insulating housing, electrical terminals to the vacuum interrupter integrated into the pressure housing, and a further pressure tight housing attached pressure tightly at the insulating housing at the movable contact side of the vacuum interrupter with the movable rod, and that the inner volume of the insulating pressure tight housing gastightly separated from the inner volume of the further pressure tight housing by a bellow, through which the movable rod is guided through and mechanically coupled to a drive, which is arranged inside the further housing.

A medium voltage circuit breaker for the use in high pressure environments, the breaker comprising:
- a vacuum interrupter including a fixed contact side and a movable contact side including a movable rod, and a drive in an insulating housing, which insulating housing is pressure tight;
- first and second electrical terminals to the vacuum interrupter integrated into the insulating housing;
- and
- a further housing, attached pressure tightly at the insulating housing at the movable contact side of the vacuum interrupter with the movable rod, the further housing also being pressure tight,
- wherein an inner volume of the insulating housing is gastightly separated from the inner volume of the further pressure tight housing by a bellow, through which bellow the movable rod is guided through and mechanically coupled to a drive,
- wherein the drive is arranged inside the further housing.
