DEVICE FOR AUTOMATIC IMPACT ON ELECTRICAL NETWORK AND ELECTRIC DRIVE FOR SUCH DEVICE Russian patent published in 2006 - IPC H02P7/20 H02J3/12 

FIELD: devices for automatic impact on electrical networks.

SUBSTANCE: proposed device incorporates voltage converter in the form of instrument transformer mounted on step-by-step regulated transformer. Instrument transformer records actual value of regulated voltage and transfers it through single electrical measurement line to electric drive; the latter is provided with means for comparing this actual value with desired one and for generating executive instruction depending on comparison results. Invention specification also includes description of adequately equipped electric drive with additional control unit that starts electric motor whenever necessary in required sense of rotation which, in its turn, actuates transformer step selector switch on step-by-step voltage regulation transformer thereby regulating supply mains control voltage.

EFFECT: reduced space requirement due to disposition of all parts directly on transformer and integration of electric drive and voltage regulator.
