  • Patent number: 8993908
    Abstract: A moving contact-carrying carriage (8) for an electrical cut-off device which comprises several seats (80) arranged for receiving several parallel moving contacts (5A-5C) offset in space, and each of them is associated with a return mechanism (65). The carriage can be coupled with an actuator mechanism (6) of the device. The carriage (8) comprises an insulating support (81) which has parallel seats (80) and a supporting structure (9), surrounding the insulating support (81), for forming a load-absorbing belt therearound. In order to couple the carriage (8) with the actuator mechanism, the supporting structure (9) comprises a connecting part (91) positioned in a front section of the insulating support (81) and passing through the central seat (80) and resting against the central moving contact (5A), on a side opposite to the return mechanism (65), for directly transmitting driving efforts of the actuator mechanism when opening the electrical circuit.

  • Patent number: 8859916
    Abstract: An electrical cut-off device provided with a control module associated with at least one cut-off module corresponding to a phase of an electrical network in which the cut-off module includes a set (5) of several moving contacts (5A-C) associated with one pair of fixed contacts. The moving contacts of the set (5) of several moving contacts (5A-C) are parallel and offset with respect to one another in order to stagger, in time, an the approach of the moving contacts with the pair of fixed contacts when closing the electrical circuit.

  • Patent number: 8723627
    Abstract: An electrical cut-off device (1) with high electrodynamic resistance in which the fixed contacts (4) and the moving contact (5) are arranged according to an architecture forming a current loop so that the Laplace electromagnetic forces, called compensation forces (Fc), generated by the circulation of the current (I) in the current loop, are oriented in a direction flowing from the inside toward the outside of the current loop, and in which the actuator mechanism (6) is arranged for moving the moving contact (5) inside of the current loop, from its switched-off position to its switched-on position in a direction (Fd) that is identical to the direction of the compensation forces (Fc).

  • Patent number: 7821253
    Abstract: A direct current measuring device having at least one first magnetic sensor and at least one second magnetic sensor sensitive to a magnetic field generated by an electric current flowing in a conductor. The measuring device includes a processing unit connected to the magnetic sensors and generates an output signal dependent on measurement signals supplied by the magnetic sensors. The processing unit includes selection means supplying the output signal and is dependent, for weak electric currents, on the first measurement signals from a first magnetic sensor, and is dependent, for strong electric currents, on the second measurement signals from a second magnetic sensor.

  • Patent number: 6621389
    Abstract: A circuit breaker is equipped with a motorized control acting on an operating member oscillating between a loaded position and a closed position, passing via a closing dead point position. When the unit is open or reset by means of the motorized control, the operating member is moved to an indexed position close to the closing dead point position, so as to minimize the closing time. The circuit breaker also has an opening dead point position. To minimize the opening-closing cycle time, the motor drives the operating member from the closed position to an indexed turning position situated between the opening dead point position and the loaded position, before changing direction.

  • Patent number: 6034858
    Abstract: The current transformer comprises a magnetic circuit associated to a primary conductor and a secondary winding connected to a trip relay. The magnetic circuit comprises a mobile part and a fixed part. The mobile part goes from an open position to a closed position when a primary current flowing in the primary conductor exceeds a preset value. The change of position of the mobile part makes the magnetic flux in the magnetic circuit vary which induces a secondary current in the secondary winding to actuate the trip relay. Application, notably to trip devices and circuit breakers.

  • Patent number: 6031703
    Abstract: The protection relay comprises a processing unit and temperature sensors associated to conductors, an ambient temperature sensor, and setting devices connected to circuits which perform tripping functions. A first short delay tripping circuit supplies a tripping order to a relay if a value of the temperature variation of a conductor exceeds a first setting threshold. A second long delay tripping circuit supplies a tripping order to the relay if a value of the temperature difference between the temperature of a conductor and the ambient temperature exceeds a second setting threshold. The protection relay is used notably for trip devices and circuit breakers.

  • Patent number: 5870009
    Abstract: The trip device comprises a magnetic circuit having a first and second fixed parts, a movable element and an adjustment device. The adjustment device comprises a shunt and an air gap arranged between the first and second fixed parts branched off with respect to the mobile element. The tripping threshold of the trip device is modified by varying the air gap distance between the shunt and the second fixed part. In a circuit breaker, the mobile element acts on an opening mechanism and an adjustment part acts on the adjustment device making the air gap distance vary. A sensor associated to the magnetic circuit supplies a measurement signal to a processing unit.

  • Patent number: 5296660
    Abstract: An electrical breaking device including a movable contact assembly. The movable contact assembly includes a support cage and upper and lower contact fingers pivotally mounted thereto on respective upper and lower transverse spindles. The upper and lower contact fingers are parallel to each other and each include a head having a movable contact at a first end thereof, and a second end opposite the first end which is connected to a flexible conductor. The lower and upper contact fingers are cooperable with a stationary contact assembly. The lower transverse spindle is positioned to be closer to the first end of the lower contact finger than to its second end. In contrast, the upper transverse spindle is positioned to be closer to the second end of the upper contact finger than to its first end. The longitudinal spacing between the upper end contact spindles yield an attraction force which counter-balances repulsion forces acting on the movable contacts through which a current flows.
