    摘要: The movable nozzle (95) of a puffer circuit interrupter (15-17) has a coaxial cylindrical shield (110) connected to its downstream end and the main movable contacts (89) connected to its upstream end. The shield (110) is electrically connected to the stationary contact terminal (44). The movable contact ring (89) and coaxial shield (110) at the upstream end of the nozzle (95) define a well shielded open gap when the interrupter gap opens.

    摘要: A circuit interrupter includes a cylindrical container (5) having an arcuate inner wall of electrically insulating material and containing an arc extinguishing fluid. A rotary shaft (7) is provided along an axis of the container (5), at least one stationary contact (3 or 4) is provided at a predetermined position on the inner wall, and a movable contact (6) is mounted on the rotary shaft (7) in such manner as to be brought into and out of engagement with the or each stationary contact. A closing member (15) is disposed at one end of the opening movement path of the movable contact (6) and substantially closes the clearance between the inner wall and the rotary shaft (7) and, when the interrupter is opened, sweeps along the inner wall of the container (5) towards the closing member (15) to compress the arc extinguishing fluid between the two members (15, 16). The compressing member (16) has a blow outlet (18) which causes the compressed fluid to blow into the space where arcs are generated upon cpening of the interrupter.

    摘要: L'invention est relative à un dispositif de soufflage magnétique et électromagnétique d'un arc électrique.
    Une bobine (28) est excitée lors de la formation de l'arc électrique et le champ magnétique engendré provoque d'une part le déplacement d'un piston (24) de soufflage pneumatique et d'autre part la rotation de l'arc par soufflage magnétique.
    Le dispositif de soufflage peut être appliqué à un interrupteur électrique.
