GAS TURBOGENERATOR Russian patent published in 2015 - IPC F25B11/00 F01D25/10 

FIELD: machine building.

SUBSTANCE: gas turbogenerator contains a turbine, asynchronous generator, turbine speed transmitter, through insulators, three-phase gas pre-heater, temperature transmitter, control box, contactor. Each phase of the gas pre-heater has multi-layer structure with external nonmagnetic current conducting pipe with temperature transmitter and winding. The asynchronous generator contains primary and secondary star-connected three-phase windings, and shifted along the stator circle by 60 degrees relatively to each other. The primary winding is connected with regulated capacitors with rectifier in zero point, and with power grid via the active power transmitter and contactor contacts. The rectifier is connected with the regulating element in form of bipolar transistor with insulated gate. The bipolar transistor with insulated gate is controlled by signal with pulse width modulation from the active power transmitter. The contactor is controlled by turbine speed transmitter. The secondary winding is connected via the electronic switch with cosine capacitors and phase outlet conductors of the winding of the gas pre-heater. The electronic switch is controlled by signal from the temperature transmitter.

EFFECT: higher energetic efficiency of the gas turbogenerator.
