PHASE-ROTARY DEVICE Russian patent published in 2018 - IPC H02H7/18 H02J3/18 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and electric power engineering, and in particular to phase-rotary devices. Phase-rotary device comprises a series transformer, each phase of a network winding being connected in series to the corresponding phase of the power line, and its valve windings are connected to the corresponding phase outputs of a switching center; multiwinding shunt transformer, each phase of the primary winding of which is connected to the corresponding phase of the power line, and the secondary windings of each phase of the shunt transformer are connected to the corresponding inputs of the switch, each phase of which consists of two identical parallel-connected branches containing a serial connection of controllable keys. Switching center inputs for connecting each secondary winding of the shunt transformer are located at each point of connection of the controlled keys of the parallel branches of the switching center, opposite terminals of the secondary windings of the shunt transformer are located on each of the parallel branches of the switch in an alternating sequence. Different outputs of various secondary windings of the shunt transformer, whose terminals of the same name are located on the same branches of the switch, are connected by additional controlled keys.

EFFECT: technical result is a reduction in cost and an increase in phase-rotary devices efficiency.
