Title:
交流誘導炉用の制御装置
Document Type and Number:
Japanese Patent JP4701250
Kind Code:
B2
Abstract:
The invention is directed to a control device for AC reduction furnaces ( 15 ) with electrodes ( 14 ) having a transformer ( 11 ) and a regulating system ( 1 ) for the controlled introduction of energy into the AC reduction furnaces ( 15 ) which controls an adjusting device ( 17 ) for the electrodes ( 14 ). The control device further has controllable power-electronics AC switches ( 13 ) which are connected in the high-current conductors on the secondary side and are connected to the regulating system ( 1 ) by an ignition line ( 16 ) for supplying controlling ignition pulses. The control device is constructed in such a way that brief fluctuations in the electric parameters are compensated only by the AC switches ( 13 ).
