•Main function and features An electric furnace transformer is used to supply power to an electric furnace , which lowers the high voltage to the furnace-required lower voltage . Its type varies with the type of electric furnace , so the transformer has many types . Currently we manufacture following types: Arc furnace transformers used for steel-smelting (including load-ratio voltage regulator type , no-load voltage regulator type , and built-in reactor type ); blast furnace transformers used for smelting of iron alloy, silicide , calcium carbide (single phase , three –phase , load ratio voltage regulator and no-load voltage regulator). All are energy –saving products with low power loss. The cooling modes are self-cooling mode, forced water cooling mode ,etc. Non-excitation -tap-changing Arc Furnace Transformer Technical Parameters Rated Power (kVA)With Series reatorPrimary Voltage (kV)Secondary Voltage (V)Rated Secondary Current(A)Type of tapingConnection symbolShort-Circuit Impedance(%)Series reactorNo-load Loss (kW)On-load Loss (kW)No-load Current(%)Rated power (kVA)Reactance Voltage Drop (%)6306 6.3 10 10.5 11200 170 116 981819no-load tap changingDd0 Dy118-9 7-8120192.48.6380026091502.7112.9100028871903.1142.91250210 180 121 1043437200163.617.52.6160043992604.1222.5200054993204.6272.42500220 190 127 110656128011.25.2322.3315082673506392.24000240 210 139 12196233408.57.6462.15000120283609.45426300260 240 210 139139004305.711.8631.980001776546015741.8 Rated Power (kVA)No Series reactorNo-load Loss (kW)On-load Loss (kW)No-load Current (%)Short-Circuit Impedance(%)BigSmall6302.211324 2610 118002.713.52.910003.1162.812503.718.52.622 249 1016004.6242.520005.6282.425006.734.52.321 238 93150841.52.2400019 217 8500063008000
