Electrical technical description
The electrical part of the equipment includes power rectifier transformers, intermediate frequency power control cabinets, compensation capacitor banks, water cooling systems, etc.
Power transformer (provided by the user)
The power rectifier transformer is used to reduce the 1OKV high voltage of the power grid to a voltage suitable for intermediate frequency power supply. This equipment adopts a 12 pulse rectifier transformer specifically designed for smelting, which is oil immersed and self cooled. The rated capacity of the transformer is 2200KVA, with a primary voltage of 1KV and a secondary voltage of 660V; Two sets of winding outputs, star and delta, with a short-circuit impedance between 6% and 8%. On the high-voltage side of the transformer, there is an unloaded manual voltage regulating switch that can be adjusted in three levels:-5%, 0%, and+5%.
