The invention relates to an operating mechanism for opening and closing at least one contact, which operating mechanism comprises, a base frame, a bridge body movable relative to the base frame between a closed position and an opened position, a rod mechanism of a first and a second link, a cam arranged on a shaft, a locking lever fixedly arranged with one end to the first link and moves with the first rod between a locked position and an unlocked position, a control shaft having a D-shaft portion with a flat surface portion and a semi cylindrical surface portion, and a lock position, in which the path of the second end of the locking lever intersects with the circumference of the cross-section of the D-shaft portion.

A locking apparatus for a hydromechanical spring energy store drive for actuating a medium-voltage or high-voltage circuit breaker is disclosed, the spring energy store drive includes a working piston, which is guided in an axial cutout in a pressure housing or working cylinder, and a spring energy store arrangement. The locking apparatus includes a first pressure region and a second pressure region, which are under elevated pressure when the circuit breaker is closed, and a third pressure region, which is unpressurized. The latching bolt can be arranged perpendicular to the working piston, via a latching apparatus, which can be arranged on a side of the latching bolt, which is to point towards the working piston and via the spring energy store arrangement, which is to be pushed away from the working piston.

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.

A bypass switch for a STATCOM and an HVDC of the present invention is characterized by: a switch body having a column; a switch head which is coupled to the column and in which a sliding part is provided so as to be slidable up and down; a sliding part which is inserted into the switch head; a driven latch which is inserted into the sliding part and fixed to a driving shaft penetrating therethrough; a driving latch which is coupled to an end of the driving shaft exposed to the outside of the switch head, and which is provided to be driven by a solenoid; a stop coupled to the front of the switch head so as to limit movement of the driven latch; a pressure bearing which is inserted into a lower portion of the sliding part and coupled thereto by a bearing pin; an elastic body provided between the sliding part and the switch body; and a rod coupled to an upper portion of the sliding part so as to be insulated by an insulator.

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.
