DEVICE FOR DISTRIBUTION OF LOADS ON TRACTION ELECTRIC MOTORS OF DIESEL LOCOMOTIVE

摘要

Usage: diesel locomotives with power transmission. SUMMARY OF THE INVENTION: A certain part of the electric energy that is supplied to the unloaded wheel pair of traction motors is first converted to mechanical energy, and then electrical energy is obtained from it, which is transferred to the loaded wheel pair of traction motors. This conversion of electrical energy is carried out using two electric DC electric machines. These machines have mechanically connected cores, series excitation windings, and independent excitation windings. An anchor winding of one (another) machine is included in a chain of unloaded (loaded) electric motors, which operates in a motor (generator) mode. The voltage of the root winding of a machine operating in the motor Oenerator) mode is directed to the agreement (opposite) to the voltage of the root windings of the traction electric motors. The independent excitation rims of both machines are connected via auxiliary contacts of the vehicle reversing switch to its control voltage source. Such inclusion of independent excitation windings allows you to change the operating mode (motor, generator) of additional electric machines when the direction of movement of the vehicle is changed and, thus, ensure the transfer of electric energy from the unloaded traction electric motor circuit to the loaded traction motor chain in any direction of its movement. electric motors. 2 ill.
