1. A high-voltage circuit breaker system having a quick disconnection function, the circuit breaker system comprising:
a circuit breaker having a contact system and a drive system mechanically connected to said contact system;
said drive system including a drive assembly and a drive shaft being a rotatably mounted crankshaft;
said crankshaft having at least three cranks, with a second crank of said crankshaft being deflected rotationally in a different direction from a first crank of said crankshaft;
a push rod connecting each crank of said crankshaft to a movable contact of said contact system;
said crankshaft and said push rod being configured to perform the quick disconnection function with a cycle of an opening movement, a closing movement, and a reopening movement of said contact system caused by a unidirectional rotational movement of said crankshaft; and
said crankshaft having an axis of rotation and said crankshaft being configured to carry out the unidirectional rotational movement with respect to said axis of rotation of between 150° and 210° from a closed position of said contact system to an open position of said contact system.
