Abstract:
1. A gas-insulated, metal-encapsulated circuit breaker comprising: an interrupter unit having a movable, driven first interrupter contact for interaction with a second interrupter contact of the circuit breaker; a closing resistor; a switch, connected in series with the closing resistor, for inserting the closing resistor in a circuit when the circuit is under load, the switch having a movable switching contact; means for mechanically coupling the switching contact to movement of the first interrupter contact, the switching contact being configured for rotation about a rotation shaft for the inserting of the closing resistor; and a first fixed axis for movement of the first interrupter contact, the second interrupter contact being arranged on the first axis, wherein the means for mechanically coupling converts linear movement in a direction of the first axis, of at least one of a drive rod of the switch and of the first interrupter contact, to a rotary movement about the rotation shaft.
