SUBSTATION FOR POWER SUPPLY Russian patent published in 2020 - IPC H02B5/00 H01F27/28 H01F27/08 

FIELD: electrical engineering.

SUBSTANCE: invention can be used in powerful transformers of current and voltage conversion. Some of the most labor-consuming parts of substations, windings of their transformers, are made on the basis of double-sided printed-circuit boards in the form of printed spirals or "turns" on their base. Consonant spirals by internal coils of each double-sided printed-circuit board are connected to each other by conductive bridges. Outer outputs of adjacent printed spirals through openings in intermediate insulators are connected to each of adjacent printed circuit boards. Windings are assembled into packages and have cooling channels. External leads of packages of "windings" are output for connection with switching and protection elements.

EFFECT: technical result consists in simplification and cost reduction of manufacture, operation, maintenance and repair of substations transformers due to possibility of replacement of damaged sections without replacement of all windings, possibility of unification; at that, denser package of windings is provided, leading to reduction of magnetic path of magnetic conductor, as a result, reduction of losses and increase in efficiency of substation.
