MULTICONTACT SWITCHING SYSTEM WITH THREE POWER CONTACT GROUPS AND DC LINK Russian patent published in 2021 - IPC H02J9/06 H02J13/00 

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 from emergency modes of operation and switching and atmospheric overvoltages, electricity metering, monitoring the quality of electricity, monitoring the amount and time of voltage outages in distribution electrical networks, sectioning and redundancy of distribution electrical networks, power lines, including those containing power sources that are not synchronized with each other. The effect is achieved by the fact that a multi-contact switching system with three power contact groups and a direct current insert 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 rectifying and inverting unit, multi-contact switching system control unit, uninterruptible power supply unit, three surge suppressors.

EFFECT: increasing reliability of the multicontact switching system, reducing the undersupply of electricity to consumers, increasing the reliability and efficiency of power supply systems for consumers, including those to which various sources of electricity are connected, including those that are not synchronized with each other.
