Engineered for Renewable Energy Volatility
Unlike standard distribution transformers, wind power transformers must handle extreme and rapid load fluctuations depending on wind conditions, alongside significant harmonic currents generated by inverters. The STELLAR renewable energy transformer utilizes an optimized core and high-grade copper winding configuration to minimize no-load losses and withstand the mechanical stresses of short circuits, ensuring stable power transmission even during peak generation spikes.
Fully Sealed and Maintenance-Free Design
Wind and solar farms are often located in remote, harsh environments such as deserts, coastal areas, or high-altitude mountains. To combat this, the transformer features a fully sealed tank design that isolates the insulating oil from the atmosphere. This prevents moisture ingress and oil oxidation, drastically reducing the aging of the insulation system and allowing for virtually maintenance-free operation across its lifecycle. The enclosure is also treated for high anti-corrosion resistance.
Exceptional Environmental Adaptability
These transformers are built to survive extremes. Rated for ambient temperatures ranging from a freezing -40°C up to a scorching +50°C, and altitudes up to 3000 meters, they maintain continuous operation without derating issues commonly seen in lesser equipment. Furthermore, the robust structural design achieves a seismic resistance of 0.4 m/s² horizontal acceleration, ensuring mechanical integrity in earthquake-prone regions.
Direct Step-Up Integration
Specifically matched for turbine output, the Low Voltage (LV) side accommodates inputs of 0.69kV, 0.8kV, 0.95kV, and 1.14kV, stepping it up directly to the 35kV (or 10kV) network via the High Voltage (HV) side. The Dyn11 vector group configuration is strictly applied to suppress third harmonics and provide a stable neutral point, which is highly beneficial for the power quality of the renewable grid connection.
