Abstract

Improvements in shielded electrical switches for high voltage with filling of gaseous fluid, characterized by providing housed in a single gas-tight metal box or container (1), which forms a single environment, all the interior parts that interconnect freely at least an interruption chamber or switch assembly (4) equipped with bielisms (9, 10) as connection to control mechanisms (8, 11, 12) external to said metal container (1), said interruption chamber (4) being immersed totally in a single gaseous fluid that acts as a filling medium for said metal container (1), as an insulating medium for the various parts under tension, and finally as a means of extinguishing by means of the interruption arc, said single gaseous fluid having the possibility of moving freely through the interior of the only environment - where there is no partition and/or partition - made up of said metal container (1), thus as well, through the connection mouths (14), inside the other armored equipment included in the installation and associated with said container (1), the said interruption chamber or switch assembly (4) being chosen among those of type of compressed gas that acts at low pressure only by axial self-blowing, substantially provided with a nozzle or orifice, appropriate to act with said single gaseous fluid.
