Transformer
The electric arc furnace transformer is one of the most representative types of the electric furnace transformer，lt isalso more frequent and intense than other kinds of transformers that the working short circuit and the harmonic shock aresubjected to operation.Therefore , high requirements have been put forward for the electric arc furnace transformer in thedesign calculation, the structure form, the manufacturing process and the test.Arc furnace transformer is one of the mostrepresentative work in the furnace transformer, short circuit and harmonic the bearing in the operation process of theimpact than other types of transformer is more frequent and more intense , so the electric arc furnace transformer, thedesign calculation, structure, manufacturing process and test are made high request.In the design scheme of transformerelectric arc furnace, in order to enhance the ability to withstand short circuit winding of large transformer by concentricstructure, winding wire preferred self-adhesive transposition wire, greatly enhance the ability to withstand short circuit oftransformer at the same time, reduce the winding eddy loss and stray loss.The main longitudinal insulation margin of theelectric arc furnace transformer is increased to improve the safety factor of its overvoltage impact during operation.In theprocess of manufacturing the electric arc furnace transformer, the advanced structure is adopted to reduce the loss of airload and enhance the ability to withstand impact.

ln line with the requirements of energy saving and consumption reduction in iron and steel industry, LF transformers,which are the main equipments used in iron and steel smelting, are aiming at reducing the power consumption per ton ofsteel and other factors. Our company pursues the following four goals in transformer equipment and manufacturing.

1.transformer itself has good energy saving characteristics, that is, no-load loss, no-oad current and load loss.As faras possible, reduce the percentage of impedance voltage and choose the right capacity on the commonly used capacity.By using the existing high-quality raw materials and using advanced technology such as small oil gap, the transformerwill truly become an energy-saving type, and the performance level is consistent with that of the developed countries.2.transformer has very stable reliability and long service life. The design technology of new structure should be verifiedby operation test and type test, and the design life is no less than thirty years.
3.requires a certain load capacity to ensure that the user in the excess nominal capacity, 20% load conditions, theoperation of the appropriate operation.
4.reduce the maintenance workload of users, users no longer in the long-term use of the core, the design ofmaintenance free time is not less than ten years. The free repair time is twenty years.
5.selection of material, structure and technology of transformer
