SAF High Voltage Compensation System
High Voltage Compensation System Used for Submerged Arc Furnace
I. Overview
Compensation equipment is a key component in metallurgical power supply systems, used to improve power factor, stabilize voltage, filter harmonics, reduce line losses, and ensure stable operation of impact loads such as EAFs and refining furnaces. Based on voltage level, compensation principle, and functional characteristics, they are mainly classified into the following types:
1. According to the voltage level: High Voltage Compensation Equipment and Low Voltage Compensation Equipment
2. According to the function: Reactive Power Compensation Device, Harmonic Mitigation Device and Integrated Compensation Device
II. High Voltage Compensation Equipment
High voltage compensation equipment is mainly used in 6-35kV power supply systems, commonly found in substation buses for impact loads such as large EAFs, SAFs, and rolling mills .
