FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, to devices of sectioning and redundancy of power transmission lines and is intended for switching, protection of electric network, accounting of electric power, control of electric power quality, control of quantity and time of voltage disconnection in distributing electric networks of three-phase current. Sectioning and redundancy station comprises an input manual control switching element, first, second, third switching elements of remote control, first, second, third output switching elements of manual control, control units of first, second, third switching elements of remote control, unit for remote control of power circuits and unit of local control of power circuits of partitioning and redundancy station up to 1 kV, current control unit, electric power accounting unit with electric energy quality control function, switching elements position monitoring unit, data transmission unit and voltage control unit.
EFFECT: technical result consists in improvement of functional capabilities and field of use due to application for switching, protection of electric network, accounting of electric energy, control of electric power quality, monitoring the number and time of voltage disconnection in three-phase current distribution networks with possibility of independent control of three power contact groups having common connection point, to perform sectioning and backup of three power networks - sections of power transmission lines.
