FIELD: electrical equipment; transportation.
SUBSTANCE: invention relates to the field of electrical equipment of railway transport. In the multi-zone rectifier, valve windings (2,3,4) of the transformer are arranged in order of 25 %, 50 %, 25 %, and in the winding circuit of 50 % (3) there is vacuum switch 6 which is open at the first stage, which allows the extreme windings to operate in parallel, which increases traction effort and reduces losses.
EFFECT: increase of traction force and increase of efficiency factor.
