FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, namely, to circuits of AC distribution networks, and can be used to power single-phase consumers of household and industrial use from a three-phase network. In the method, the three-phase-single-phase transformer contains zigzag windings, the beginnings of their first halves are the inputs of the phases A1, B1, C1 of the supply network, and the beginnings of their second halves are interconnected and are the output of a single-phase load. Also, the other single-phase load output is connected to the input of the supply network phase A1. Above windings are made on a three-rod magnetic circuit.
EFFECT: technical result consists in reducing the material consumption, dimensions and providing the possibility of connecting one of the load outputs to the neutral wire of the supply network.
