• Low-Harmonic Magnetic Circuit: High-permeability silicon steel sheets and optimized core structures minimize core saturation tendency and self-generated harmonics.
• Low-Harmonic Winding: Advanced winding techniques (e.g., foil winding) and materials reduce eddy current losses, leakage flux, copper losses, and additional harmonics.
• Enhanced Insulation & Cooling: Reinforced insulation and optimized cooling systems (e.g., forced-oil air cooling) ensure long-term reliability and extended service life under harmonic-induced thermal stress.
• Improved Short-Circuit Resistance: Enhanced resilience to abnormal operating conditions caused by harmonics. - Coordinated Optimization & Smart Monitoring (Optional):
• Synchronize with furnace control systems or external active power filters (APF) and static var generators (SVG) for holistic power quality management.
• Optional smart monitoring systems track key parameters (harmonics, temperature, load rate) in real time for predictive maintenance and remote oversight.
Advantages
• Efficient Harmonic Mitigation: Filters key characteristic harmonics at the source, significantly reducing grid THD and protecting grid/equipment.
• Source-Level Mitigation: Directly addresses harmonics at the transformer, ensuring thorough suppression.
• Improved Power Quality: Stabilizes voltage waveforms for reliable operation of furnaces and sensitive equipment.
• Extended Equipment Lifespan: Prevents harmonic-induced overheating and damage to transformers, cables, and capacitors, lowering maintenance costs.
• Optimized Reactive Compensation: Minimizes harmonic interference with compensation devices, enhances power factor correction, and reduces line losses.
• Standards Compliance: Ensures harmonics meet GB/T 14549, IEEE 519, and other global power quality standards.
• Compact & Reliable: Integrated design saves space and simplifies system architecture.
• Enhanced System Efficiency: Reduces harmonic-related losses and boosts overall energy efficiency.
Application Scenarios
Ideal for harmonic-intensive applications demanding high power quality:
• Electric arc steelmaking furnaces
• Medium-frequency/power-frequency induction melting furnaces
• Submerged arc furnaces
• Power supply systems for other large-scale nonlinear furnace loads
