Embodiment Construction

[0044] figure 1 A schematic diagram of a circuit breaker 1 according to the invention is shown. The circuit breaker 1 comprises a make-up energy store 2 arranged on a fastening part 3 of the circuit breaker 1 . The switch-on energy store 2 is connected to the cam 6 via the pressure shaft 5 by means of the articulated connection on the eccentric 4 . The cam 6 is mounted rotatably about an axis of rotation 7 and rests with its outer surface 8 on the cam element 9 of the switching shaft 10 . The switching shaft 10 is rotatably mounted about a rotational axis 11 and comprises a second drive lever 12 articulated to a first end 13 of a disconnecting energy store 14 . The second end 15 of the tripping accumulator 14 is connected to a double-armed lever 17 to which the tripping accumulator 14 is hingedly coupled at a first end 18 and which is movable around The rotating shaft 9 is supported. The second end 20 of the double-armed lever 17 is in turn connected in an articulated mann...

Abstract

In order to form a circuit breaker having at least one pole arrangement, which comprises a movable contact, having a twin-armed lever, which is mounted such that it can rotate, for opening and closing the movable contact, having a switch-on energy store, and having a cam disc, which is coupled to the switch-on energy store and, via an actuating element, to a first end of the lever, the second endof the lever being connected to the movable contact piece of the pole arrangement, and having at least one switch-off energy store, which circuit breaker has a simple and compact design, the invention proposes that the actuating element is a switching shaft, which interacts with the cam disc, is mounted such that it can rotate and is connected to the first end of the twin-armed lever via the switch-off energy store.

Description

technical field [0001] The invention relates to a circuit breaker having: at least one pole arrangement comprising a moving contact; a rotatably mounted double-armed lever for opening and closing said moving contact; switching an energy store and a cam coupled to the connection accumulator and via an operating element to the first end of the lever, wherein the second end of the lever is coupled to the movable pole device the contacts are connected; and at least one disconnect accumulator. Background technique [0002] Such a circuit breaker is known from DE4138333C2. In such a circuit breaker, the rotatably mounted double-armed lever has, at its first end facing the cam element / cam, an operating element in the form of a rotatably mounted roller which cooperates with said cam element, wherein The cam element is turned by the energy stored in the spring element as a switch-on energy store. The movable contact is movably arranged relative to the first contact between an open...
