电炉电极电压采集器的设计及应用

Designing and Application of Submerged Arc Furnace Three- phase Electrode Voltage Collector

阐述了矿热炉二次电压自电炉变压器二次出线端子(低压侧)接入,由于矿热炉短网各支路感抗的不相等,导致取得的二次电压与实际运行电压误差较大。进而对矿热炉冶炼炉况的正确判断及稳定运行产生一定影响,为此在矿热炉中应用三相电极采集电压的方法,为矿热炉冶炼工艺需求及功率检测提供定量准确的运行数据。

The secondary voltage is from electric furnace transformer secondary outlet terminals （low voltage side）.As the inductive reactance of each branch of the submerged arc furnace short network is not equal,a bigger error between the acquired secondary voltage and the actual operating voltage oc-curred,and this causes adverse effect on correct judgment of furnace condition and furnace stable opera-tion.Therefore,three -phase electrode voltage collector is applied,which can provide accurate quantita-tive data for the smelting process requirements and the power detection.
