摘要： A clutch device of a gear transmission system of a circuit-breaker spring operating mechanism includes an energy storage shaft, a large gear, and a small gear. At an energy storage holding position of the large gear, a toothless and special teeth area is arranged corresponding to the small gear. A clutch cam is provided in a cavity in the large gear at the area and a backward extended part and may be reset by a resetting spring. In the area, the large gear includes a first special tooth, a second special tooth, and a space between the first and second special teeth. When energy storage is completed, the small gear pushes the first special tooth to push the large gear and energy storage shaft to the energy storage holding position that is away from a friction dead zone, and the small gear is automatically disengaged from the large gear.

摘要： A drive apparatus for a tensioning shaft of a spring energy drive of an electric switch has a kinematic chain for connecting a drive element to the shaft and a control element. Within the chain, a first link which can be coupled to the shaft in rotationally fixed fashion and a second link arranged coaxially regarding the first link and capable of rotating under the force of the drive element are coupled to one another in a form-fitting and/or force-fitting manner by a coupling element which is moved by the control element on one of the two links such that the link coupling is released when a predetermined first angular link position is reached and is produced again when a predetermined second angular link position is overshot. To provide the drive apparatus with a more compact configuration, the coupling element can be moved in the radial direction of the shaft.

摘要： An arrangement is disclosed for, in particular, activating a transport pawl including a movable activation device which is secured to a carrying structure and, in a first activation phase, can be moved out of the position of rest into an end position, counter to the force of a restoring spring, and in a second activation phase can be moved out of the end position and back into the position of rest, under the force of the restoring spring. In order to configure the arrangement in such a way that the operator of the activation device is alerted to incompletely executed activation of the activation device, in at least one embodiment a locking mechanism is provided which locks the activation device in the direction of its position of rest during the first activation phase when a first intermediate position is reached, and releases it again when a second intermediate position is reached. The arrangement can be applied in particular in tensioning devices for spring energy stores of electric switches which have a tensioning shaft and a manual drive for turning the tensioning shaft.

摘要： The spring-loaded mechanical control mechanism for a circuit-breaker in a high-voltage or medium-voltage grid comprises a toothed wheel turned by a spring from a first angular position to a second angular position, and a cog wheel co-operating with the toothed wheel to displace it from the second angular position to the first angular position so as to tension said spring. The toothed wheel has a peripheral set of teeth including a retractable segment on which at least four teeth are spaced apart from one another at a constant pitch identical to the pitch of the primary teeth.

摘要： A motor operator for a circuit breaker is disclosed. The motor operator includes a motor drive assembly connected to a mechanical linkage system for driving an energy storage mechanism from a first state of a plurality of states to a second state of a plurality of states. The motor operator also includes an energy release mechanism coupled to the mechanical linkage system for releasing the energy stored in the energy storage mechanism. The mechanical linkage system includes a recharging cam being driven by the motor drive assembly. The recharging cam rotates a drive plate rotatably mounted to the system. A linear carriage is coupled to the drive plate and the linear carriage manipulates an operating handle of a circuit breaker. The recharging cam is disengaged from the drive plate when the energy storage mechanism is compressed into an energy storage state and the drive plate is latched into a position corresponding to the energy stored state. The drive plate is released from its latching position by the energy release mechanism and the stored energy of the energy storage mechanism is released to manipulate the handle of the circuit breaker. The recharging cam is reconnected after the energy of the energy storage mechanism has been released.
