Abstract
A damping and latching mechanism for a Thomson coil-based actuator used to open and close the separable contacts of circuit interrupters in circuit breakers uses magnetorheological fluid to actively control the damping of opening and closing strokes in a circuit breaker in order to decrease wear and tear on components that can result from contact-based damping mechanisms and to maintain the open and closed states of separable contacts in the circuit breaker.
