POWER SUPPLY SYSTEM FOR ASYNCHRONOUS ELECTRIC MOTORS OF DIESEL ENGINE COOLING FANS AND TRACTION ENGINES OF DIESEL LOCOMOTIVE Russian patent published in 2022 - IPC B60L1/00 B60L3/12 B60L50/12 B61C5/00 

FIELD: transportation.

SUBSTANCE: invention relates to power supply to auxiliary equipment of vehicles. Power supply system of asynchronous electric motors of diesel engine cooling fans and traction engines of diesel locomotive contains traction generator, auxiliary generator, asynchronous AC motors of the diesel engine cooling fan and the diesel locomotive traction engine cooling fan, the programmable microprocessor connected to the temperature sensors recording the temperature in the diesel engine and the diesel locomotive traction engine, with current regulators, power three-phase uncontrolled voltage rectifier and two inverter converters. At that, system microprocessor stores information on limits of thermal modes in diesel engine and in traction engine, on limits of voltage norm on excitation windings of generators and on limits of norm of voltage converted by inverter converters for supply of asynchronous motors of diesel engine cooling fans and traction motors. Note here that microprocessor controls and corrects voltages at excitation windings of system generators, as well as voltages feeding asynchronous motors of diesel engine cooling fans and diesel locomotive traction motor.

EFFECT: improvement of efficiency of cooling of diesel engine and traction engines of diesel locomotive.
