The authors suggest a system of automatic control of braking force at recuperation ofd.c.electric  locomotives, in which the necessary braking effort is generated by the decisive unit, constructed on the basis of a microcontroller, according to the p... see more

The article provides brief description of a technical project for reequipping the electric locomotives VL80? and VL80S with smooth thyristor adjusters of tractive motors with the single automatic control system.

A functional chart of DC electric locomotives recuperative braking automatic control system, with power supplies of excitation windings from a static activator, has been developed.

In this paper the results of elaboration of automated microprocessor system are given. This system allows us to control and measured the parameters of code current of automatic locomotive signaling system and to define spectral composition of traction cur... see more

The results of statistical research of wear of automatic coupler body butts and thrust plates of electric locomotives are presented in the article. Due to the increased wear the mentioned elements require special attention.

The article briefly expounds the upgrading of ? functional chart of automatic control system of recuperative braking for DC electric locomotives with power supply of excitation windings coming from a static activator.
