摘要：A vacuum interrupter of more improved large current interrupting capabilityand dielectric strength is disclosed. The interrupter has a pair of separable contact-

electrodes (13, 24), a vacuum envelope (4) generally electrically insulating and enclosingthe pair therewithin, a contact-making portion (19) of 20 to 60% IACS electrical

conductivity being a part of one contact-electrode (13) of the pair and being into and outof engagement with the other contact-electrode (24) of the pair, an arc-diffusing portion(20) of 2 to 30% IACS electrical conductivity being the other part of the one contact-electrode (13) and being electrically and mechanically connected to the contact-makingportion (19) so as to be spaced from the other contact-electrode (24) when the contact-electrodes (13, 24) are into engagement, and means (14, 15) for applying an axialmagnetic field in parallel to an arc established between the contact-electrodes (13,24)when separated.
