Abstract: A disconnector for electric power equipment filled with dielectric liquid, especially transformers, applicable in protecting the operation of electric power equipment. The disconnector contains at least two cylindrical current-limiting fuses situated inside a tank, and each 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 piece of electric power equipment. The disconnector is characterized in that the current-limiting fuses are placed in a common housing, in which a slide with a pilot is situated, and to the slide there are inseparably fixed moving contacts, which move together with the slide when the slide makes a to-and-fro motion. The to-and-fro motion takes place as a result of the operation of a tripping device situated in the current-limiting fuses and of the compression or stretching of springs fixed to the pilot and to a fixing disk.
