Abstract: A drive mechanism for an inertia cone crusher having a drive transmission to rotate an unbalanced mass body within the crusher and to cause a crusher head to rotate about a gyration axis at a tilt angle formed by an axis of the crusher head relative to the gyration axis. A torque reaction coupling is positioned in the drive transmission between the mass body and a drive input component and is elastically displaceable and/or deformable. In particular, the torque reaction coupling is configured to: i) transmit a torque from the drive input to the mass body and ii) to dynamically displace and/or deform elastically in response to a change in the torque resultant from a change in the tilt angle of the crusher head so as to dissipate the change in the torque to the drive transmission.

Abstract: A high-voltage circuit breaker has an interrupter unit, a closing resistor and a switch which is connected in series with the closing resistor. The interrupter unit has a driven first interrupter contact which can move along an axis and interacts with a second interrupter contact, which is arranged on the axis in order to open and close the high-voltage circuit breaker. The switch has a switching contact which can rotate about a rotation shaft (D) and whose rotary movement is coupled by of a link control to the movement along the axis (A1) of the first interrupter contact.

Abstract: The switching chamber for a heavy-duty circuit breaker has a first arcing contact piece, a second arcing contact piece, a heating chamber, and an insulating nozzle. The first or second arcing contact piece can be moved by means of a drive. The heating chamber is used for temporarily storing quenching gas heated by an arc that may burn between the contact pieces. An insulating nozzle has a throat that is connected to the heating chamber, and which is used for guiding a quenching gas flow. During an opening operation, the two arcing contact pieces reach a maximum relative speed that is at least 1.3 times as great as a relative speed of the two arcing contact pieces. The relative speed being required for capacitive switching.

Abstract: The heavy-duty circuit breaker contains a first moveable arcing contact piece and a second moveable arcing contact piece as well as an auxiliary drive for driving the second arcing contact piece. An arc may burn between the arcing contact pieces. The heavy-duty circuit breaker has a heating chamber for temporarily storing quenching gas heated by the arc and a throat for guiding a quenching gas flow, which throat is connected to the heating chamber by a channel. The throat can be blocked by one of the two arcing contact pieces, which is the blocking contact piece. The auxiliary drive is designed such that, during an opening operation, a movement direction reversal of the second arcing contact piece from a movement in opposite directions to a movement in the same direction of the two arcing contact pieces takes place, if the throat is no longer blocked by the blocking contact piece.

Abstract: The switching chamber for a heavy-duty circuit breaker which can be filled with a quenching gas has a first arcing contact piece (1) and a second arcing contact piece (2), of which at least one (1; 2) can be moved by means of a drive. An arc (4) may burn between the contact pieces (1, 2). A heating chamber (11) is used for temporarily storing quenching gas heated by the arc (4). An insulating nozzle (5) has a throat (6), which is used for guiding a quenching gas flow and is connected to the heating chamber (11). During an opening operation, a maximum relative speed v12,max of the two arcing contact pieces (1, 2) in relation to one another is reached which is at least 1.3 times as great as a relative speed v12,c of the two arcing contact pieces (1, 2) which is required for capacitive switching.
