CONNECTING UNIT AND NETWORK FOR ENERGY DISTRIBUTION Russian patent published in 2019 - IPC H02H3/02 H01H89/00 H01H7/00 

FIELD: electrical engineering.

SUBSTANCE: technical result is achieved by means of method (2) of operating the power grid with a plurality of connecting blocks (2, 2',…) with the following steps: - opening of electronic switch (231) of connecting block (2) using block (26) of evaluating connecting block (2); - waiting for certain time interval (Δt); - measuring potential (U) at the output of electronic switch (231) using the evaluation program and corresponding voltage measuring device (232); - comparing the measured potential (U) with a preassigned value (U_Ref); - setting the release parameter depending on the drop of the measured potential (U) below a preassigned value (U_Ref); - opening of mechanical disconnector (233) depending on the release parameter, and especially by: - creating priority level (Prio) for the intended shutdown process; - performing the shutdown process depending on the priority level (Prio); - if the shutdown process is performed and the parameter for releasing the increase in the counter content (Z) is not set.

EFFECT: technical result consists in increasing the operational reliability in the operation of power grids.
