Abstract (en)
[origin: WO2020025407A1] The invention relates to a vacuum interrupter (2), comprising: a housing (3) having at least one annular ceramic insulating element (4), which forms a vacuum chamber (6), a contact system (8) having two contacts (9, 10), which are movable relative to one another. The invention is characterized in that a capacitive element (12) having two electrodes (14) and having a dielectric material (16) arranged between the electrodes (14) is provided, the capacitive element (12) being interlockingly mounted on the insulating element (4) and having a capacitance between 400 pF and 4000 pF.
