Definitions

  • the invention relates to an electric breaker circuit breaker with air cutoff having an improved arc breaking capacity.
  • DC and air-interruptions electrical circuit breakers which comprise electrical contacts, connected to input and output terminals of the electric current and being selectively movable relative to each other between a closed position, in which respective contact areas of the first and second electrical contacts are in contact with each other to allow the flow of direct electric current between the first and second electrical contacts, and an open position, in which these contact areas are distant from each other.
  • circuit breakers make it possible to protect electrical systems against abnormal conditions, such as an electrical overcurrent or a short circuit, by rapidly interrupting the flow of electric current when such an abnormal condition is detected.
  • abnormal conditions such as an electrical overcurrent or a short circuit
  • fast is meant that the electric current must be interrupted in less than 100ms or, preferably, less than 10ms after detection of the abnormal condition.
  • the conductors are moved away from each other to their open position.
  • an electric arc is formed between their contact zones. This arc must be off in order to interrupt the flow of electric current.
  • the electric arc is blown in the direction of an arc-breaking chamber, where it is extinguished, thus allowing interrupt the flow of the current.
  • Such a blowing effect is partly caused by an electromagnetic force exerted on the electric arc, under the effect of the magnetic field created by the flow of electric current in the electric arc itself.
  • the magnetic field generated by the electric arc itself is not sufficient to move it by blowing towards the breaking chamber.
  • the electric arc can thus persist long between the two electrical contact zones. This is not desirable because the circuit breaker does not quickly interrupt the flow of current, which can cause a situation that is unsafe.
  • FR 2 632 772 B1 a circuit breaker in which a permanent magnet is disposed on an arc horn at the inlet of the interrupting chamber, so as to generate a constant magnetic field for moving an electric arc towards the chamber cutoff regardless of the value of the electric current.
  • a device does not give complete satisfaction and more is complicated to produce industrially and requires sometimes significant modifications of existing circuit breakers for its integration.
  • the invention intends to remedy more particularly by proposing a reversible electric circuit breaker with reversible polarity and in which an electric arc can be reliably interrupted even for low values of electric current intensity. and can be made industrially in a simple manner.
  • the circuit breaker further comprises a magnetic circuit including a magnet and generating a magnetic field which is able to guide, in the direction of the breaking chamber, an electric arc formed between the contact zones in the open position, the magnetic field generated by the magnetic circuit having for this purpose curved field lines which extend substantially perpendicular to opposite side walls of the arc-forming chamber, these side walls being arranged on both sides of the contact zones substantially parallel longitudinally, these converging field lines, at a central region of the arc forming chamber containing the contact zones, towards the breaking chamber extending parallel to the longitudinal plane, and the magnet is capable of generating a magnetic field greater than or equal to 0.5 Tesla, or, preferably, greater than or equal to 1 Tesla.
  • the magnetic field created by the magnet and the magnetic circuit exerts a force on the electric arc which first moves the latter away from the electrical contact areas and perpendicularly to the longitudinal plane. Due to the configuration of the magnetic field lines, the force exerted on the electric arc then changes direction, so as to then direct the electric arc to the breaking chamber. Because of the symmetrical configuration with respect to the longitudinal plane, the electric arc is moved to the interrupting chamber irrespective of the direction of flow of the electric current in the circuit breaker. In addition, the magnetic circuit is easily integrated with existing circuit breakers, without imposing significant structural changes.
