FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to devices for sectioning and redundancy of power transmission lines and is intended for switching, protecting the electrical network and equipment of a multicontact switching system from emergency operating modes and switching and atmospheric overvoltages, electricity metering, power quality control, monitoring the amount and time of shutdown voltage in distribution electrical networks of three-phase current. The effect is achieved by the presence in the multi-contact switching system with three power contact groups connected to a common point, three output switching elements of manual control, three switching elements of remote control, three control units for switching elements of remote control, a unit for receiving and transmitting data, a control unit for a multi-contact switching system, an uninterruptible power supply unit and three surge suppressors.
EFFECT: increasing reliability of the multicontact switching system, reducing the undersupply of electricity to consumers and increasing the reliability and efficiency of consumer power supply systems.
