Patent number: 9018558Abstract: The disclosure relates to a gas circuit breaker switch (5) which can be integrated inside a switching device insulated in a dielectric gas, said switch (5) comprising an arc chute (1) inside which a fixed contact (3) and a moving contact (4) are arranged. The integration of the contacts (3, 4) inside at least one casing (19, 20) corresponding to the arc chute (1) allows reducing distances between phases, in addition to preventing any incident in one phase from affecting the remaining phases, and finally more compact electrical equipment is obtained. The switch (5) also comprises at least one generation means (6) for generating at least one gas, at least one blowout/intake means (7) for at least one extinguishing gas and at least one generation means (2) for generating a magnetic field, such that the electric arc generated between the contacts (3, 4) of the switch (5) can be extinguished by combining said means (6, 7, 2).Type: GrantFiled: May 31, 2010Date of Patent: April 28, 2015Assignee: Ormazabal Y CIA, S.L.Inventors: Norberto Sainz de la Maza Escobal, Juan María Casado Cartón, José Manuel Inchausti Sancho, José María Torres Novalbos
