Abstract (en)
[origin: US4329551A] An alternating current interrupter is contained in a sealed elongated housing filled with dielectric gas, such as SF6. The interrupter comprises a pair of separable stationary and movable contacts and a magnetic blow-out arc extinguishing device including an annular coil disposed coaxially with a first ring-shaped electrode which surrounds the stationary contact. The coil produces a radial magnetic field in the arcing zone causing the arc to rotate rapidly along the first electrode which is secured to the inner edge of the coil's front face in order to reduce the electrodynamic repulsion forces between said coil and electrode. A metallic shield is disposed between the arcing zone and the outer portion of the front face which is not covered by the first electrode.
Abstract (fr)
L'invention concerne un interrupteur à arc tournant. Au contact fixe (12) de l'interrupteur est associé un ensemble de soufflage magnétique, constitué par une carcasse (18) de support d'une électrode annulaire massive (32) accolée à une bobine de soufflage (22) logée dans un évidement annulaire (20) ménagé dans la carcasse. L'interrupteur est du type à enveloppe (10) isolante remplie d'hexafluorure de soufre. Se référer à la figure unique.
