The first contact set includes a first electric arc contact element and a first nominal current contact element. The first nominal current contact element can be moved relative to the first electric arc contact element. A first transmission is introduced in a kinematic chain in order to generate a relative movement of the first nominal current contact element and the first electric arc contact element. The first transmission is operationally connected between a stationary counter bearing and the first electric arc contact piece.

Abstract: An exemplary medium or high voltage switch has a first set of contact elements and a second set of contact elements. Each contact element includes an insulating carrier carrying conducting elements. In the closed state of the switch, the conducting elements align to form one or more current paths between terminals of the switch along an axial direction. For opening the switch, the contact elements are mutually displaced by means of one or two drives along a direction perpendicular to the axial direction. The switching arrangement is arranged in a fluid-tight housing in a gas of elevated pressure or in a liquid. The switch has a high voltage withstand capability and fast switching times.

Abstract: An insulating tube (18) located between the main contacts (12b, 14b) and the arcing contacts (12a, 14a) of an interrupting chamber (10) of a high-voltage or medium-voltage circuit-breaker makes it possible to modify the distribution of the equipotential lines (V) during breaking. Thus, it is possible to reduce the electric field on the contacts, and thus to improve the breaking and the dielectric strength in the open position. The insulating tube (18) can also serve for transmitting movement between the contacts (12, 14) for triggering the circuit-breaker.

Abstract: The heavy-duty circuit breaker can be filled with a quenching gas and contains a first moveable arcing contact piece and a second moveable arcing contact piece as well as a drive for driving the first arcing contact piece and 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 an insulating nozzle, which has a throat for guiding a quenching gas flow, which throat is connected to the heating chamber by means of a channel. The throat can be blocked at least partially by one of the two arcing contact pieces, which is referred to as 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 at least partially blocked by the blocking contact piece. Advantageously, the gear is a gear which is driven by the drive.
