THREE-PHASE HIGH-VOLTAGE TRANSFORMER WITH VOLTAGE CONTROL FOR SUPPLY OF 12-PHASE RECTIFIER-INVERTER AGGREGATE

摘要

FIELD: rectifier-inverter aggregates. SUBSTANCE: network and valve windings are put on concentration centers. Each of them occupies two concentration centers located side by side. Half of parts of valve winding are Y-connected and each part of second half includes delta-connected section. EFFECT: increased efficiency, improved mass and size characteristics and reduced coefficient of nonsinusoidality of voltage of supply network. 5 dwg
