Abstract: A charging mechanism for charging a stored-energy spring of a stored-energy spring mechanism includes a charging gear coupled to the stored-energy spring, an intermediate shaft coupled to the charging gear, an idler gear that can be driven by a charging motor, a freewheel coupled to the idler gear, and a dog clutch that couples the freewheel to the intermediate shaft in order to charge the stored-energy spring and uncouples same from the intermediate shaft in the charged state of the stored-energy spring. The dog clutch has a first clutch block coupled to the intermediate shaft for conjoint rotation, and a second clutch block connected to the freewheel. The first clutch block can be displaced along an axis of rotation of the intermediate shaft between two end positions and, in an intermediate position between the end positions can be freely rotated only in a direction of rotation with respect to the second clutch block.

Abstract: A charging mechanism charges a stored-energy spring of a stored-energy spring mechanism. The charging mechanism contains a charging gear coupled to the stored-energy spring, an intermediate shaft coupled to the charging gear, an idler gear driven by a charging motor, a freewheel coupled to the idler gear, and a dog clutch that couples the freewheel to the intermediate shaft to charge the stored-energy spring and uncouples same from the intermediate shaft in the charged state. The dog clutch contains a first clutch block that is non-rotatably coupled to the intermediate shaft, a second clutch block connected to the freewheel, and a synchronizer ring arranged between the clutch blocks and is non-rotatably coupled to the first clutch block. During a rotation relative to the second clutch block, the synchronizer ring couples in a form-fitting manner to the second clutch block in a first direction of rotation about the axis of rotation.

Abstract: A charging mechanism charges a stored-energy spring of a stored-energy spring mechanism. The charging mechanism contains a charging gear coupled to the stored-energy spring, an intermediate shaft coupled to the charging gear, an idler gear, a freewheel coupled to the idler gear, a locking mechanism for releasably locking the charging gear in a charged state of the stored-energy spring, and a dog clutch that couples the freewheel to the intermediate shaft to charge the stored-energy spring and uncouples same from the intermediate shaft in the charged state of the stored-energy spring. The dog clutch contains a first clutch block that is non-rotatably coupled to the intermediate shaft, a second clutch block connected to the freewheel, and a synchronizer ring disposed between the clutch blocks and is non-rotatably coupled to the first clutch block, the synchronizer ring is pressed against the second clutch block when the dog clutch is closed.

Abstract: An arrangement for a high-voltage circuit breaker includes at least one movable electric contact piece of an interrupting unit. The at least one movable contact piece is disposed on a switch rod and the switch rod is movably mounted between an outer region and an inner region of the housing of the interrupting unit. The switch rod is guided in a solely linear manner in the arrangement. A method for driving the at least one movable electric contact piece includes using the switch rod to move the contact piece. The switch rod is moved in a solely linear manner along the longitudinal axis of the switch rod.
