Power supply units are designed for automatic adjustment of metal remelting procedure in open-type electric arc furnaces of with working volume up to 65 tons. Several versions of supply units of different power and voltage are available depending on furnace features.Use of water cooling and powerful new thyristors allows to minimize the power supply unit needed installation floor area.
Microprocessor control system is one of the advantages, that provides the following:
- Optimization of furnace power input
- Built-in unit status diagnostics and testing
- Connection with external systems through RS-485 interface.
Main control system functions:
- Automatic control of the technological variables (current stabilization at a given level)
- Automatic protection from "drip short" over-current
- Current control during automatic ignition of the arc
- Limiting the level of impact on the supply mains during dynamic loads in the melting process.
