FIELD: electrical engineering.
SUBSTANCE: invention relates to electric track circuits. The reverse traction current balancing apparatus with controlled magnetic amplifiers, connectable to a standard double or single throttle transformer, comprises measuring transformers of the reverse traction current components in the track rails, an electric power source, a comparison and control unit, current-limiting resistances, transistor switches, as well as safe coupling elements of the transistor switches with control windings of the magnetic amplifiers, implemented on isolation transformers, pulse diodes, and capacitors. The controlled magnetic amplifiers are therein made with permanent magnets as part of the cores, wound whereon are the working and control windings.
EFFECT: ensured alignment of the components of the reverse traction current in the track rails with any type of asymmetry.
