METHOD FOR ADJUSTING POWER OF THREE-PHASED ALTERNATING-CURRENT ELECTRIC ARC FURNACE

摘要

FIELD: electric engineering, in particular, electric metallurgy and methods for adjusting power in three-electrode alternating-current arc furnaces.;SUBSTANCE: during movement of electrode of one of three phases in working space of arc furnace to achieve symmetric mode of operation, reactive component of short circuit resistance is adjusted by changing capacities of capacitors batteries, connected in parallel to two other phases of short circuit. Capacity of batteries is selected on basis of empiric relation.;EFFECT: increased productiveness and decreased specific loss of electric energy.;1 tbl
