| 成果简介 | NOVELTY - Group of inventions relates to electric traction systems of vehicles. Method of controlling an electric drive of a single-phase-direct current electric locomotive with controlled excitation converters consists in the fact that during breakaway and acceleration control signals are supplied to transistors of each individual transistor controlled excitation converter, at that, make-up currents appear, which are equal to the value of independent excitation current, then rectifier-inverter converters (RIC) appear, motor currents appear, and with smooth increase of motor currents, excitation currents will be maintained at a given level by reducing make-up currents. After acceleration, the power constancy characteristic is switched to with successive excitation of traction motors with full excitation current or power constancy characteristic with weakened excitation current. Also disclosed is an electric locomotive electric drive control device containing a driver’s control panel and a microprocessor system. USE - Machine building. ADVANTAGE - Higher efficiency of electric drive. 5 cl, 7 dwg, 2 tbl |
