发明名称 AC switches connected to a regulating system by an ignition line for supplying controlling ignition pulses
摘要 <p>Disclosed is a control device for AC reduction furnaces (15). The furnace has electrodes (14), a transformer (11) and a regulating system (1) for the controlled introduction of energy into the AC reduction furnaces. The control device controls an adjusting device (17) for the electrodes. The control device has controllable power-electronics AC switches (13) which are connected in high-current conductors on the secondary side of the transformer, and are connected to the regulating system 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.</p>
