Patent ID: 8692645

Claim:
A disconnector for electric power equipment containing fuses, comprising three cylindrical current-limiting fuses which are situated inside a containing tank filled with dielectric fluid and filled with dielectric fluid each current-limiting fuse is electrically connected with external phase power supply and through fixed contacts and moving contacts of the disconnector with the active part of the electric power equipment, characterized in that the cylindrical current-limiting fuses are situated in a common housing in which there is a slide with a pilot, and the slide has moving contacts inseparably fixed to it, which contacts move together with the slide when the slide makes a to-and-fro motion along an axis of slide travel that takes place as a result of the operation of a tripping device situated in the current-limiting fuses and of compressing and stretching of springs fixed to the pilot and to a fixing disk coupled to said common housing, wherein said cylindrical current-limiting fuses are situated in said common housing in such a way that the longitudinal axes of the cylindrical current-limiting fuses are situated parallel to one another, and a projection of the longitudinal axes on a plane determines three points which when connected to one another form the vertexes of a triangle in whose area a projection of the axis of the slide travel is situated.
