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