FIELD: electrical engineering.
SUBSTANCE: invention is related to electric engineering, in particular to open distribution devices of electric stations, and can be used on them for generation of generated electric energy. In open distribution device of electric station with two units of generator-transformer and three lines there are sixth, seventh and eighth switches with disconnector on one side, wherein sixth switch is connected in series with third switch, and its disconnector is connected to the connection point of the disconnector of the second line with the second disconnector of the second switch, the disconnector of the third line is connected to disconnect switches of the seventh and eighth switches, which are connected in series with the fourth and fifth switches, respectively.
EFFECT: technical result consists in improvement of reliability of device in case of faults in disconnection of SC on connection or faults of type "short circuit in both sides" of any of switches, as well as when they are in repair.
