Reactive power controlling device of induction furnace
专利汇可以提供Reactive power controlling device of induction furnace专利检索，专利查询，专利分析的服务。并且PURPOSE:To maintain the safety of a device, by changing the capacity of a capacitor connected in parallel to an output terminal of an electric power source, and a capacitor connected to a meter relay of a reactive power meter, in accordance with the residual molten metal quantity of an induction furnace. CONSTITUTION:Between the molten metal quantity in an induction furnace and reactive power, specified relation exists, and between inclination of the induction furnace and the molten metal quantity, a specified relation exists, as well. By detecting an inclined angle, the capacity of a capacitor in a reactive power controlling device is adjusted. The capacity of a capacitor provided in parallel to a transformer 10 of a main circuit power source, and the capacity of a capacitor provided in parallel to a meter relay 3 of a reactive power meter are adjusted suitably in accordance with the residual molten metal quantity. Even if the reactive power of the induction furnace is varied, when it is within the range which does not generate cutoff of an overcurrent of the main circuit, the capacity can be adjusted by the meter relay 3.，下面是Reactive power controlling device of induction furnace专利的具体信息内容。
