  • Patent number: 10242814
    Abstract: An electric arc extinction chamber comprises a stack of electric arc splitter plates. The splitter plates define an inlet of the extinction chamber that is to be present facing electric contacts, and a back of the extinction chamber. At least one permanent magnet is present inside the extinction chamber in a central zone in the width direction of the extinction chamber and beside the back thereof. The magnet presents magnetization having a non-zero component along an axis extending between the inlet and the back of the extinction chamber.
    Type: Grant

  • Patent number: 9299509
    Abstract: An electrical switching device (1) which comprises at least one double breaking pole provided with two fixed contacts (3, 4) that cooperate with two moving contacts (5, 6) arranged so as to move in a breaking plane (P) and define, with every fixed contact, a breaking zone. The device comprises a permanent magnet (11, 12) housed in an insulating holder arranged in the immediate environment, next to each breaking zone, symmetrically with respect to the breaking plane and oriented so as to generate a magnetic excitation vector parallel to the breaking plane (P) so that the induced electromagnetic force (FE) moves and stretches every electric arc (E1, E2), generated when opening the electrical circuit, in a direction perpendicular to the breaking plane (P), leading to the extinction of the electric arc regardless of the polarity of the magnet and/or of the current.
