Abstract
A vacuum interrupter includes at least one insulating body, a fixed contact, a fixed contact flange, a moving contact having a longitudinal axis of the moving contact, a moving contact flange, a moving contact bearing, and a bellows. The fixed contact is stationarily disposed in the fixed contact flange, the moving contact is moveably guided in the moving contact bearing and the moving contact is moveably secured to the moving contact flange by the bellows. The bellows is secured to the moving contact flange by a first bellows end and the bellows is secured to the moving contact by a second bellows end. An increased pressure resistance of the vacuum interrupter against ambient pressures over 1 bar is achieved by a sleeve which is secured to the moving contact against movements along the longitudinal axis of the moving contact, and which is guided through the moving contact bearing.
