METHOD TO CONTROL ELECTRIC DRIVES OF COAL PREPARATION COMPLEX OF BLAST FURNACES

摘要

FIELD: electricity. ^ SUBSTANCE: in the method to control electric drives of a coal preparation complex of blast furnaces separate supply is arranged: power circuits are supplied from a device of automatic stand-by power connection, and control circuits - from a source of uninterrupted power supply, therefore electric drives circuits are not disassembled, and driving mechanisms remain in operation. ^ EFFECT: higher reliability of complex operation in case of short-term disappearance of supply voltage. ^ 1 dwg
