摘要： A switching device for an electric circuit, the switching device comprising: at least one phase having a movable contact which can be coupled to/separated from a corresponding fixed contact; a kinematic chain operatively associated to the movable contact; driving means adapted to move the kinematic chain between a first position and a second position for actuating the movable contact; and control means adapted to control the driving means. The kinematic chain is adapted to reach the second position from the first position before reaching a dead-point position, and the control means are adapted to: detect a loss condition of a power supply associable to and suitable for operating the switching device, while the kinematic chain is in the second position; and control the driving means to move the kinematic chain away from the second position when the loss condition is detected, in such a way that the kinematic chain passes through the dead-point position and reaches a third position between the dead-point position and corresponding blocking means of the switching device.

摘要： Disclosed is a withdrawable device of main circuit for a circuit breaker. A ring-shaped guide recess is formed at a central part of a transfer nut screw-coupled to a lead screw, and supporting surfaces are formed on side surfaces of the guide recess. And, rotation prevention pins are elastically supported by springs in a moving direction of the transfer nut, and are selectively locked, thereby allowing the transfer nut to perform an idle operation. Accordingly, a structure for an idle operation of the transfer nut is simplified, and the number of components is reduced. An axial load is attenuated to a plane-contact distributed load, not a point-contact concentrated load, thereby preventing damage of the components. Also, a vacuum circuit breaker has enhanced reliability of the idle operation at a run position and a test position.

摘要： In a grounding switch for an encased high-voltage switching system, the movable switching piece is moved by a rotating drive shaft. This drive shaft passes through the housing of the grounding switch. To design the contact elements that transfer the ground potential to the movable switching piece as simply as possible, the drive shaft consists of electrically conductive material. In addition, the drive shaft is insulated as it enters the housing. The drive shaft is also coupled with means to transfer the ground potential, e.g., a current strip, outside the housing. Thus, the drive shaft serves both to transfer force and to transfer potential. A switch blade is designed to be elastically deformable in part, and serves as the movable switching piece. This grounding switch for an encased, compressed-gas-insulated high-voltage switching system can also be used as an insulated grounding switch to carry out measurements.

摘要： A circuit maker and breaker has a removable arc chute for interrupting an arc formed between the movable and stationary contacts. A pivotally movable interlock device is mounted in a cavity in the insulating base of the circuit maker and breaker in the region where the contact-carrying armature is movable into engagement with a magnetic yoke to close the movable contact of the circuit maker and breaker into engagement with the stationary contact. The pivotally movable interlock device includes a plug-like member which is movable into the path of movement of the contact-carrying armature to prevent closure of the armature if the arc chute is not properly positioned on or is absent from the circuit maker and breaker. The interlock device is actuated by a lever which is engaged by a surface on the arc chute as the arc chute is slid into proper position on the circuit maker and breaker, to thereby move the interlock device out of plugging or blocking relation to the armature. In the absence of the arc chute, or in case of improper positioning of the arc chute, the interlock device will move about its pivotal axis to interpose the interlocking plug member into the path of closing movement of the contact-carrying armature to prevent closing of the armature and thus to prevent closing of the movable contact relative to the stationary contact. In one embodiment of the invention, when the arc chute is absent or improperly positioned the interlocking plug member moves due to the force of gravity into the path of closing movement of the contact-carrying armature; while in another embodiment of the invention when the arc chute is absent or improperly positioned the stored energy of a biasing spring moves the interlocking plug member into the path of closing movement of the contact-carrying armature. In the second embodiment, the force of the spring member may be, but is not necessarily, supplemented by the force of gravity in moving the plug member into the path of closing movement of the contact-carrying armature.
