Patent attributes
A circuit breaker includes a vacuum interrupter. The interrupter includes a first movable electrode to which a first contact is connected and a second movable electrode to which a second contact is connected. The interrupter is operable between an open state and a closed state. In the open state, the first contact and the second contact are separated by a contact gap distance. In the closed state, the first contact and the second contact touch each other. The circuit breaker includes an ultrafast actuator operatively connected to each of the first and second movable electrodes. The ultrafast actuator is configured to change the vacuum interrupter from the closed state to the open state by simultaneously moving the first contact in a first direction along a first distance portion of the contact gap, and the second contact in a second direction along a second distance portion of the contact gap.
