Abstract
A vacuum valve includes: a vacuum vessel; a cylinder; a partition wall separating an inside of the vacuum vessel from an inside of the cylinder; a movable conductor penetrating the partition wall being movable in an axial direction; a fixed contact fixed inside the vacuum vessel; a moving contact integrated with the movable conductor and being capable of separating from the fixed contact and coming into contact with the fixed contact in association with movement of the movable conductor; a lid that covers an end of the cylinder, the end being on a side opposite to the partition wall; a connecting rod penetrating the lid and coupled to the movable conductor via an insulating rod as an insulator; and a holder that holds the connecting rod while preventing movement of the connecting rod toward the fixed contact in a state where the moving contact is separated from the fixed contact.
