Abstract

In order to use locomotives efficiently and prolong their service life, it is important to study the operation of locomotives' electrical equipment. In particular, the traction generator of the locomotive type 2TE10M and the reverse current flow in the current circuit of traction electric motors are important. These currents were detected during the study of the causes of contact melting of VSh contactors. In this case, when the traction motors are operating in the mode of attenuation of the magnetic field, after switching off the drive of the traction generator, the resistors of the traction generator of the traction motor, the reverse current flows from the shunts of the traction motor. This article describes in detail the features of the manifestation of reverse currents in the current circuits of traction generators and traction electric motors with the practical-scientific basis and scientific manuscripts of scientists

Keyphrases: Contactor, diesel locomotive, EDS, excitation, load circuits, magnetic flux, reverse current, train contactors
