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 triggering mechanism is for a switching device, in particular for low-voltage devices and systems, medium-voltage devices and systems, and/or high-voltage devices and systems. The triggering mechanism includes a lever, equipped with two rolls for blocking purposes.

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.

Implementations of the subject matter described herein provide a switching apparatus including an energy storage changement mechanism that can realize the main shaft energy storage and direction changement by using only one solenoid. Furthermore, the switching apparatus can be adopted in both two position ATS and three position ATS to satisfy different application scenarios or different market requirements. In addition, all transfers can be achieved by independent manual and electric operation, and each transfer action only requires powering a single solenoid.

A tensioning mechanism for tensioning a pre-loaded spring of a spring-loaded accumulator drive. The tensioning mechanism includes a tensioning wheel coupled to the pre-loaded spring, an intermediate shaft coupled to the tensioning wheel, an idler gear that can be driven by a clamping motor, a freewheel coupled to the idler gear, a locking mechanism for detachably locking the tensioning wheel in a tensioned state of the pre-loaded spring, and a dog clutch configured to couple the freewheel to the intermediate shaft in order to tension the pre-loaded spring and to uncouple same from the intermediate shaft in the tensioned state of the pre-loaded spring.

A locking module of an arming system including accumulation device, the module including a lever, second end including a bearing surface, the accumulation device exerting a thrust force on the first end when it is in the armed state; a lock element intended to adopt a first position to oppose the thrust force and a second position to stop opposing the thrust force; the module being characterized in that a shoe fixed to the lever is interposed between the bearing surface and the contact surface when the bearing surface is bearing against the contact surface, the width of the surface of the shoe in contact with the contact surface being greater than the width of the bearing surface.

A latching device for an operating mechanism for an electrical switching apparatus. The device has a locking member movable between a first position and a second position. In the first position the locking member is arranged to lock a drive member of the operating mechanism in a locked position, and a force of the drive member being applied to a contact portion of the locking member. In the second position the locking member is arranged to release the drive member from the locked position. At least in the first position the locking member is arranged to bear against the counter roller. A tripping member is movable between a first position locking the locking member and a second position releasing the locking member. The locking member has a first portion and a second portion. The first portion is rotatable connected to a first link around a first pivot axis, which first pivot axis is movable perpendicular to its direction. The second portion is rotatable connected to a second link around a second pivot axis and movable perpendicular to its direction. The second link is rotatable connected to the tripping element around a third pivot axis. Movement of the tripping member from its first position to its second position initiates movement of the contact portion out of force-transmitting relation with the drive member.
