GENERATOR OF TELEMETRIC SYSTEM SUPPLY Russian patent published in 2011 - IPC E21B47/22 

FIELD: electricity.

SUBSTANCE: generator of telemetric system supply comprises a protective vessel, an electric slot, at least one fixation unit, a rotor with a hydraulic turbine and a device to convert mechanical energy into an electric one, besides, a magnetic coupling is installed in it, which has master and slave half-couplings and a device of mechanical energy conversion arranged in the form of a Van de Graaff generator, a shaft of which is connected to a hydraulic turbine rotor via a conical reducer and a slave magnetic half-coupling. The Van de Graaff generator is arranged in the form of a master pulley of electric insulation material and a slave pulley of metal and a dielectric tape pulled onto these pulleys, which are accordingly fixed on the master and slave shafts. A current-collecting disk is connected to the slave pulley. The generator comprises at least one compensator of pressure and temperature expansion communicating with a cavity of a master half-coupling.

EFFECT: simplified design, increased reliability and capacity of generator with reduction of diametrical dimensions and weight of electric generator.
