SECONDARY OF POWER SUPPLY SOURCE WITH POWER TAKEOFF FROM PHASE WIRE OF INDUSTRIAL FREQUENCY HIGH-VOLTAGE POWER TRANSMISSION LINE Russian patent published in 2013 - IPC H02H3/08 G05F1/569 

FIELD: electricity.

SUBSTANCE: proposed device comprises a primary converter, which is formed by a closed magnetic conductor, on which the secondary winding is placed, and a phase wire is pulled into the central hole of the closed magnetic conductor, at the same time winding clamps form output clamps of the primary converter, and output clamps of the secondary winding of the primary converter are connected to input clamps of the voltage converter-controller via a serially connected non-polar capacitor. A load is connected to output clamps of the converter-controller. Current flowing in a wire excites electromagnetic field in a magnetic conductor, intensity of which is determined by the ratio where I - the value of current force in the phase wire, l_av - the medium line of the closed magnetic conductor. Intensity of the magnetic field induces voltage on clamps of the secondary winding, which is proportionate to the number of turns where U - valid value of output voltage of the primary converter in the idle mode, I_av - medium line of the closed magnetic conductor, S - cross section of the magnetic conductor, k - derivative of a linear section of the main curve of magnetisation of magnetic conductor material, I_min - minimum value of current force in the phase wire.

EFFECT: higher level of power taken from a phase wire of an industrial frequency high voltage power transmission line to a relatively higher load exceeding Ohm units, with preservation of small dimensions and weight of a device.
