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.
