POWER SUPPLY GENERATOR OF BOTTOMHOLE TELEMETRIC SYSTEM Russian patent published in 2010 - IPC H02K7/18 H02K35/02 E21B47/00 

FIELD: electricity.

SUBSTANCE: power supply generator of telemetric system comprises device of mechanical energy conversion into electric one, for this purpose magnetic coupling is installed between rotor and device of mechanical energy conversion into electric one, and coupling includes master and slave half-couplings, and device of mechanical energy conversion into electric one is arranged in the form of electrostatic generator connected by shaft to slave half-coupling. Electrostatic generator is made in the form of group of disks from dielectric material, installed on shaft between metal disks, which comprises collecting brushes at both sides. Electrostatic generator is installed in sleeve of electric insulation material, which is installed inside protective body. Magnetic coupling is arranged as end and cylindrical, half-coupling is connected to rotor, and slave one - to shaft. Inner cavity of master coupling is filled with lubricating liquid via hole.

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