Intelligent Drive: The Efficient Transformation Path for Distribution Transformers above 10kV
1.Introduction1.1 Urgent Need for Upgrading Distribution TransformersRising Load DensityDuring peak hours, transformers often operate overloaded, raising temperatures (by 15–25°C in extreme cases). Prolonged heat speeds up insulation degradation (like in paper-oil systems), boosting failure risks—overloaded units have up to 40% higher failure rates.Power Quality DisturbancesVoltage fluctuations > ±10% of nominal values disrupt sensitive gear (medical devices, data cente
