FIELD: electrical equipment.
SUBSTANCE: invention relates to electrical equipment. Three-phase single-phase transformer contains input and output terminals, to which is connected a transformer having primary windings in all three phases and two secondary windings in phases A and C. Primary windings are connected in a “zigzag” with a winding connection of phases A and B, B and C, C and A. First end leads of the primary windings are connected to the input terminals, two of the second end leads of phases A and C are interconnected. Secondary windings are turned on and connected to the output terminals. Third of the second end leads of phase B is directly connected to the neutral working conductor of the supply network.
EFFECT: technical result is to ensure an even load distribution across the three phases and increase the capacity.
