Abstract (en)

[origin: WO2019115178A1] The invention relates to a vacuum interrupter tube (10), comprising at least one insulating body (20), a fixed contact (30), a fixed contact flange (40), a moving contact (50) having a longitudinal axis (56) of the moving contact (50), a moving contact flange (60), a moving contact bearing (70), and a bellows (80), wherein the fixed contact (30) is stationarily arranged in the fixed contact flange (40), the moving contact (50) is moveably guided in the moving contact bearing (70) and the moving contact is moveably secured to the moving contact flange (60) by the bellows (80), wherein the bellows (80) is secured to the moving contact flange (60) by a first bellows end (82) and the bellows (80) is secured to the moving contact (50) by a second bellows end (84), wherein an increased pressure resistance of the vacuum interrupter tube (10) against ambient pressures over 1 bar is achieved by a sleeve (90) which is secured to the moving contact (50) against movements along the longitudinal axis (56) of the moving contact (50), and which is guided through the moving contact bearing (52).
