HIGH-VOLTAGE BOREHOLE GENERATOR Russian patent published in 2011 - IPC E21B47/00 H01F38/00 

FIELD: electricity.

SUBSTANCE: high-voltage borehole generator is equipped with protective housing, electric connector, at least one attachment assembly, rotor with hydraulic turbine and conversion device of mechanical energy to electric energy. Conversion device of mechanical energy to electric energy is made in the form of mechanical generator and Tesla transformer, which are connected by means of electric conductors. At that, Tesla transformer is made in the form of primary and secondary windings and installed in tight cavity and isolated from protective housing. Magnetic coupling containing drive and driven half-couplings is installed between rotor and conversion device of mechanical energy to electric energy. Tight partition containing parts from magnetic permeable material is arranged between driven and drive half-couplings. At that, drive half-coupling is connected to rotor, and driven coupling is connected to shaft. Inner cavity of drive half-coupling is filled with lubricating fluid. On upper edge of rotor there is filling opening of lubricating fluid to the cavity of drive half-coupling. Generator includes at least one pressure and temperature expansion compensator interconnected with cavity of drive half-coupling.

EFFECT: simplifying the design, improving reliability and power of generator at decrease of diametrical dimensions and weight of electric generator.
