Abstract
A high-voltage circuit breaker system has a rapid disconnection function that results in an opening, closing, and reopening movement of a contact system. A circuit breaker having the contact system and a drive system that is mechanically connected to the contact system. The drive system includes a drive unit and, in addition to the drive unit, a drive shaft that is designed as a crankshaft. The crankshaft is connected to a mobile contact of the contact system via a push rod, and the cycle of opening, closing, and reopening movement of the contact system results from a unidirectional rotational movement of the crankshaft.
Claims6
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.
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 rotation about said axis of rotation of between 350° and 360° plus 10° for the opening movement and the closing movement of said contact system.
