摘要： A control device for a movable contact relative to a fixed contact of a vacuum bottle of an electrical switching device. The control device includes a principal mechanism for disconnection and connection of the contacts, of the mechanical energy accumulation type. The control device further includes an auxiliary disconnection-assistance mechanism arranged such as to accumulate mechanical energy when the movable contact is moved towards the connection position and such as to restore the mechanical energy thus accumulated in such a manner as to exert an additional disconnection force in the form of an impact tending to move the movable contact from the connection position towards the disconnection position when the movable contact is immobilized in the connection position despite the action of the principal disconnection force.

摘要： A switchgear includes a movable part capable of reciprocating movement, a movable contact coupled to the movable part, a member that biases the movable contact, a latch capable of switching between a first state in which movement of the movable contact is restricted and a second state in which movement is permitted, a part that accommodates the movable part and the movable contact therein, a fixed contact provided outside of the accommodating part, and a moving part that moves with the movable contact. The latch is switched to the second state when the movable contact has moved against the biasing force. The accommodating part contains a first region and a second region, which is on a side of the fixed contact with respect to the first region within a range of movement of the moving part. The first region has an inner diameter smaller than that of the second region.

摘要： A circuit breaker having a movable tulip contact and a vacuum interrupter together connecting a first terminal to a second terminal of the circuit breaker. The tulip contact has a first end having contact fingers removably attached to a stationary contact of the first terminal, and a second end that is electrically connected to the second terminal. The vacuum interrupter has a first electrode assembly that is electrically connected to the first terminal, and a second electrode assembly that is electrically connected to the second terminal. The tulip contact and stationary contact provide a first conductive path from the first terminal to the second terminal when the tulip contact is connected to the stationary contact. The vacuum interrupter provides a second conductive path from the first terminal to the second terminal when the vacuum interrupter is in a closed position.

摘要： Embodiments provide a switch, including a control system, first and second manipulating mechanisms. The control system emits an operating instruction to the second manipulating mechanism when the wire works normally, the operating instruction instructing the second manipulating mechanism to perform an opening action or a closing action; the control system emits a first and second action instructions to the first and second manipulating mechanisms, respectively, when the wire fails, the first action instruction instructing the first manipulating mechanism to perform a first action, and the second action instruction instructing the second manipulating mechanism to perform a second action, the cooperative action between the first manipulating mechanism and the second manipulating mechanism implements redundancy of the switch operating; and the time taken by the first manipulating mechanism to implement the first action is different from the time taken by the second manipulating mechanism to implement the second action.
