SWITCH HEAD OF LOAD STAGES, AS WELL AS SWITCH OF LOAD STAGES WITH HEAD OF SWITCH OF LOAD STAGES Russian patent published in 2020 - IPC H01H9/00 

FIELD: machine building.

SUBSTANCE: invention relates to head (20) of load step switch for switch (10) of load stages and comprises first zone (21), which is formed in head (20) of load step switch and through which insulating fluid (17) of load step switch (10) can flow; second zone, which is separated from first zone (21) by means of wall; detector device for detection of increased flow rate of insulating fluid medium (17), comprising a flow shutter, which is located in first zone (21) and, starting from preset flow rate of insulating fluid medium (17), is tilted from first position to second position; first coupling magnet, which is fixed on gate and is in second position of flow shutter in close proximity to wall; second clutch magnet, which is located in close proximity to wall (22) in second zone; switch, which is located in the second zone and is connected to the second coupling magnet so that tilting the flow shutter from the first position to the second position actuates the switch.

EFFECT: technical result consists in simplification of transformer design with stepped regulation of voltage under load.
