【発明の名称】アーク炉電極の電流制御装置
Document Type and Number:
Japanese Patent JP3092284
Kind Code:
B2
Abstract:
PURPOSE:To slowly apply a current limit without cutting an arc of an electrode even when a current regulator is in malfunctioning or the like. CONSTITUTION:In an adder 20, a deviation between a value of a current setter 10 through a switch 12 closed by an operation command and a current actual value list is taken and inputted to a current regulator 214. In an adder 16, a deviation between a value of a limit current setter 14 and the value list is fetched and inputted to a PI regulator 30. An output of the current regulator is applied to a saturable reactor 26 through a high limiter 28, to control a current of an arc furnace electrode, not shown, by an output list of the saturable reactor 26. Further, the high limiter is constituted such that its upper limit value is regulated by the PI regulator 30.
