COMPARISON OF LOW-VOLTAGE COMPENSATION AND LONGITUDINAL COMPENSATION FOR TRANSFORMER OF SUBMERGED ARC FURNACE
At present,the transformers of submerged arc furnace used in smelting and production of most series of ferro-alloy varieties adopt low-voltage compensation or longitudinal compensation.Although the principles of low-voltage com-pensation and longitudinal compensation are the same,the compensation characteristics are different,and the applicabi-lity of producing ferroalloy varieties is also different.Meanwhile,due to different compensation methods,there should be some differences in transformer and parameter design.The rated voltage of the capacitors for the two compensation me-thods should also meet the actual production needs.And the natural power factor should be taken as the standard in smel-ting operations to ensure that the thermal efficiency of the electric furnace is controlled within a reasonable range.
