Solusyon sa Harmonic Suppression Furnace Transformer
Pag-analisis sa Problema
Ang mga modernong elektrikong furnaces (espesyalmente ang arc furnaces, medium-frequency furnaces, ug power-frequency induction furnaces) nag-generate og dako nga higher-order harmonic currents nga gipasok sa grid sa panahon sa operasyon tungod sa ilang nonlinear load characteristics (e.g., violent fluctuations sa electric arcs, rectification/inversion processes). Ang mga harmonics mao kini ang resulta:
- Kamutan sa Grid: Distorted grid voltage waveforms (increased THD), naaffect ang normal nga operasyon sa uban pang sensitive equipment sa sama nga grid.
- Pagsira sa Equipment: Overheating, intensified vibration, accelerated insulation aging, ug padayon nga pagsira sa transformers, cables, compensation capacitors, etc.
- Nataasan nga Power Loss: Additional thermal losses gikan sa harmonic currents nga naga-flow sa grid impedance.
- Gamay nga Power Factor: Bisag adunay installed compensation capacitors, ang harmonics mahimong magrender sa reactive power compensation devices nga ineffective o magamit pa sa pag-amplify sa resonances.
- Measurement Errors: Compromised accuracy sa energy metering ug monitoring instruments.

Core Technologies & Measures
- Built-in High-Efficiency Harmonic Filter:
• Ang core sa solusyon kini nagintegreha og optimally designed harmonic filter nga nagtarget sa characteristic harmonics (e.g., 5ᵗʰ, 7ᵗʰ, 11ᵗʰ, 13ᵗʰ) nga giproduce sa furnace loads.
• Ang compact, space-saving filter gi-integrate diretso sa transformer para easy installation.
• Gamiton ang LC resonance, kini naghatag og low-impedance path aron mobasa ug filter sa specific harmonics near the source, significantly reducing grid-injected harmonic currents (THD reduction complies with GB/T 14549, IEEE 519, etc.). - Optimized Transformer Design:
• Low-Harmonic Magnetic Circuit: High-permeability silicon steel sheets ug optimized core structures minimize core saturation tendency ug self-generated harmonics.
• Low-Harmonic Winding: Advanced winding techniques (e.g., foil winding) ug materials reduce eddy current losses, leakage flux, copper losses, ug additional harmonics.
• Enhanced Insulation & Cooling: Reinforced insulation ug optimized cooling systems (e.g., forced-oil air cooling) ensure long-term reliability ug extended service life under harmonic-induced thermal stress.
• Improved Short-Circuit Resistance: Enhanced resilience sa abnormal operating conditions caused by harmonics. - Coordinated Optimization & Smart Monitoring (Optional):
• Synchronize sa furnace control systems o external active power filters (APF) ug static var generators (SVG) para holistic power quality management.
• Optional smart monitoring systems track key parameters (harmonics, temperature, load rate) sa real time para predictive maintenance ug remote oversight.
