摘要： The invention relates to a contact arrangement particularly intended for current limiting low-voltage circuit breakers, the contact arrangement having an elongated movable contact (10) which, at its mid-point, is rotatably journalled about a rotational axis (A) directed perpendicular to the longitudinal axis of the contact. The movable contact cooperates with two fixed contacts (20, 21) which are arranged on opposite sides of the movable contact. In the closed position of the switching device, the movable contact is pressed against the fixed contacts with the aid of a torsion spring (18) which extends parallel to the rotational axis of the movable contact and which, on one side of the movable contact, is in engagement with the movable contact and, on the opposite side, is in engagement with the stand of the switching device.

摘要： The invention relates to a contact arrangement, intended for a current-limiting low-voltage circuit breaker, with an elongated contact carrier (1) rotatably journalled at its mid-point, the contact carrier being arranged between two U-shaped fixed contact carriers (2) arranged spaced from each other. The fixed contact carriers have a contact leg (3) which, via a mid-portion (5), is connected to a connecting leg (4). The mid-portion exhibits a rectangular opening (6), through which the movable contact carrier (1) extends. Upon a short circuit, the contacts are opened because of electrodynamic repulsion forces between the contact legs (3) and the movable contact carrier (1). This repulsion force is reduced when the contact distance increases, but the reduction is compensated by an increasing attraction force between the movable contact carrier (1) and the connecting legs (4). In this way a greater contact-opening force is obtained during the breaking operation.

摘要： The invention relates to an electromagnetic operating device intended for medium-voltage and high-voltage circuit breakers. The operating device comprises an opening magnet (11) and a closing magnet (15), each of which comprises an operating coil (12, 16), a magnetic core (13, 17) and an armature (14, 18) to operate the movable contact system of the circuit breaker. The two magnetic cores (13, 17) are integrated into one single magnet body (20). The oeperating coils (12, 16) are connected to a common energy source (30) via separate semiconductor switches (31, 32). By energizing the respective operating coil (12, 16), the two armatures (14, 18) are translatorily displaceable along the longitudinal axis of the magnet body (20) for, respectively, opening and closing of the circuit breaker.

摘要： The invention relates to an electromagnet with a magnet coil (10, 11) and a magnetic circuit consisting of a fixed core (12, 13) and a rotating armature (16). In the rest position of the armature the magnetic circuit exhibits two series-connected air gaps (21, 22) located inside the magnet coil. The magnet is primarily intended to be used as a kicker for directly actuating the contact system of an electric switch to achieve rapid breaking and limitation of the current in case of a short circuit.
