INSTALLATION FOR ALTERNATIVE ENERGY SUPPLY FOR ELECTROCHEMICAL PROTECTION OF MAIN GAS PIPELINE Russian patent published in 2022 - IPC F03G7/04 

FIELD: power industry.

SUBSTANCE: invention relates to the field of energy. The installation for alternative energy-saving of electrochemical protection means of main pipelines includes a Pelton turbine impeller with a protective grid installed on the gas pipeline, driven by a gas flow. To increase reliability and eliminate resistance on the shaft of the Pelton turbine impeller, a radial magnetic bearing and a thrust magnetic bearing on permanent magnets are used. To eliminate leaks from the Pelton turbine impeller housing, a magnetic coupling is used, through which the torque is transmitted from the drive shaft to the slave shaft using a magnetic field. To compensate for the difference in revolutions of the Pelton turbine impeller and to ensure constant revolutions of the generator shaft on permanent magnets, a variator transmission is used.

EFFECT: generating electrical energy to the means of electrochemical protection by transferring the kinetic energy of the gas by the impeller of the Pelton turbine at the moment of rotation, transmitted to the electric current generator.
