  • Hybrid circuit breaker having a switch with return on closure
    Patent number: 9099267
    Abstract: A hybrid circuit breaker for use in the field of medium and high-voltage hybrid circuit breakers comprising an arc-control device (110), a vacuum switch (20) and a single mechanical control apparatus for controlling the opening and closing of the vacuum switch (20) with the control apparatus comprising a control rod (31) for controlling the movement of a movable contact (22) relative to a stationary contact with the movable contact secured to a movable control rod (32), via a holding system including a flexible toroidal helical spring (38) placed in a groove of the movable contact and in a groove located in the movable control rod and further comprising an energy accumulation system including a spring (34) for causing the flexible toroidal helical spring (38) to release the movable control rod from the movable contact and cause the movable contact to make contact with the stationary contact.
