FIELD: transport. ^ SUBSTANCE: invention relates to railway transport vehicles, particularly to DC electric locomotives and aims at perfecting anti-skid device. Proposed device comprises resistors to bypass armatures of traction motors with the help of contactors and relay systems that reveals skidding, reduced armature current and that of excitation in skidding of wheel pair and terminates skidding via increase in potential factor of adhesion. ^ EFFECT: higher reliability and reduced electric power losses. ^ 1 cl, 2 dwg |
