CONTACT ASSEMBLY OF VACUUM INTERRUPTER

PROBLEM TO BE SOLVED: To provide a contact assembly capable of preventing a contact from being deformed and damaged due to generation of stress during the contact operation of the contact.SOLUTION: A contact assembly of a vacuum interrupter includes: a stationary contact 3; a stationary electrode 4 connected to the stationary contact 3; a movable contact 2 movable to a first position in contact with the stationary contact 3 or a second position separated from the stationary contact 3; a movable electrode 1 connected to the movable contact 2 and driving the movable contact 2; and a contact support member RM1 which is provided around the movable electrode 1 so as to be in contact with the movable contact 2 in order to reduce a stress applied on the movable contact 2 and the movable electrode 1 when the movable contact 2 moves to the first position, and increases a contact area in contact with the movable contact 2 together with the movable electrode 1.
