Product Details
Low voltage side reactive power compensation system (SAF) SAF secondary LV compensation is applications of LV compensation technologies to the secondary LV side of Submerged Arc Furnace. That is to apply modern control and conductor technologies to connect big capacity, big current super low voltage capacitors to the compensation device of SAF secondary side. Big reactive power will flow though LV power capacitor circuit, and will not flow though conductors and transformers and power grid of the before compensation points, as the power factor improved, active output of transformer will improved also, and inactive losses of transformer and conductors are reduced greatly. The compensation system is not only just for compensations but also to help the power factor of SAF working above 0.92, and can reduce inactive losses of conductors and primary side voltage, diminish harmonic waves, keep 3 phases in balance, improve output of transformer. The design we made is single phase dynamic compensations, which helps diminish imbalance of 3 phases, to keep the meet of SAF power center with furnace hearth center, enlarge smelting pool, heat concentration, improve materials surface temperature, speed the reactions, and to aim at product quality and production improvement and energy saving. The secondary LV compensation is not only reduce lasses of primary power grid supply but also helps furnace power factor over 0.92, and reduce inactive loss of conductors, improve transformer output, and to make sure more active power delivery to electrodes. Above all, LV conductor’s compensation has more advantages than the others. It works at the end of conductors, which not only improved HV side compensation power factor (if had any), but also compensated conductors inactive loss between transformer and electrodes, and as output of transformer active power improved, then energy saved.
