    • The invention relates to a method for detecting a performance drop in components that are impinged upon with electric current or which can be brought into contact therewith in arc furnaces, whereby an electric arc is initially produced from an electrode during the operation of said furnaces. According to the invention, the blaze of the arc furnace is detected close to the furnace and the measuring data relating to the blaze is fed from the point of measurement to a measuring and regulating device that is disposed in a protected location where it is processed. Control signals are sent to an actuator if deviations occur from a predefinable value, whereby the actuator influences the operating mode of the arc furnace and, more particularly, interrupts the power supply. The invention also relates to a device for detecting the consumption and/or breakage of components that can be impinged upon by electric current or brought into contact therewith in arc furnaces that possess a furnace vessel that can be closed by means of a lid. According to the invention, measuring elements (41) for the detection of UV or infra-red light are provided. Said measuring elements (41) are connected to a measuring and regulating device (43) via measuring lines (42). The measuring and regulating device (43) is connected to the actuator (45) via control lines (44), whereby said actuator acts upon the operating mode of the arc furnace.

    • A method and system for stabilizing energy consumption in multiple loads, or in single multi-phase loads. The method and system also compensates for unbalance in multi-phase loads. A central controller monitors variable reactances in the loads and identifies situations of power and/or current fluctuation and/or unbalance. It determines appropriate corrective action by the other loads/phases to compensate for the power and/or current change or unbalance due to the problematic load, and it issues control signals instructing variable reactor controllers associated with the other loads to adjust accordingly. The method and system may by applied to electric arc furnace installations. In this context, the method and system provide an electrode position controller coupled to the feed rate controller so as to predictively anticipate the introduction of new source material and lower the electrodes so as to prevent arc extinguishment while the variable reactors maintain predetermined power set­points. The electrode position controller may be used in place of the variable reactance control system to take corrective action to address power and/or current changes or unbalances.
    • 一种用于稳定多个负载或单个多相负载能耗的方法和系统。 该方法和系统还补偿多相负载不平衡。 中央控制器监视负载中的可变电抗,并识别功率和/或电流波动和/或不平衡的情况。 它由其他负载/相位确定适当的校正动作,以补偿由于有问题的负载引起的功率和/或电流变化或不平衡,并且发出控制信号,指示与其他负载相关联的可变电抗器控制器相应地进行调整。 该方法和系统可以应用于电弧炉安装。 在这种情况下,该方法和系统提供耦合到馈送速率控制器的电极位置控制器,以便预测性地预测引入新的源材料并降低电极,以便在可变电抗器保持预定功率设定点时防止电弧熄灭。 可以使用电极位置控制器来代替可变电抗控制系统以采取纠正措施来解决电力和/或电流变化或不平衡。
