Power Supply System

High-voltage power supply: Access high-voltage electricity from the power grid (usually 10kV~35kV), and deliver it to the submerged arc furnace transformer through the high-voltage switchgear.

Transformer: Converts high-voltage electricity into low-voltage, high-current power suitable for the submerged arc furnace (usually several hundred volts, with current reaching tens of thousands of amperes).

Busbar: The conductive system connecting the transformer and the submerged arc furnace electrodes, usually made of copper bars or copper tubes, requiring low resistance and good heat dissipation.

Distribution system: Provides power to auxiliary equipment of the submerged arc furnace (such as cooling systems, feeding systems, etc.).

The main functions of the submerged arc furnace automation system include:

Electrode position control: Automatically adjusts the electrode position based on the furnace reaction conditions to control the internal temperature.

Feeding control: Automatically controls the feeding speed and amount according to the production process.

Power regulation: Controls the input power of the submerged arc furnace by adjusting electrode current and voltage.

Data acquisition and analysis: Collects real-time data such as temperature, current, and voltage for analysis and optimization.

Fault diagnosis and alarm: Automatically diagnoses system faults and issues timely alarms.

High reliability: Electrical equipment and control systems must have high reliability to ensure continuous and stable operation of the submerged arc furnace.

High-precision control: Achieves high-precision control of parameters such as electrode position and feeding speed through the automation system.

Energy-saving and efficient: Optimizes the power supply system and control strategies to reduce energy consumption and improve production efficiency.
