Abstract
A vacuum interrupter, including: an insulating housing; a movable end cap; a stationary end cap; a pair of movable and stationary contacts; and a pair of shields. The pair of shields is fixed on the movable end cap and the stationary end cap, respectively. The insulating housing, the movable end cap, and the stationary end cap cooperate to form a closed space. The closed space includes a movable fracture and a stationary fracture. The movable fracture is formed by the pair of movable and stationary contacts for carrying rated current and disconnecting capacitive load whereby achieving breaking performance of the vacuum interrupter. The stationary fracture is formed by the pair of shields. When the pair of stationary and movable contacts reaches a full open position, the stationary contact and the movable contact enter the pair of shields, respectively.
