Oil-Immersed Converter Transformer for Renewable Energy Integration

The HVDC converter transformer is a core device connecting the AC power grid with converter valves for energy conversion between AC and DC systems. It provides electrical isolation to reduce mutual interference between systems and ensure safe transmission. Designed for long-distance, large-capacity power transmission including cross-regional grid interconnection and renewable energy integration.

Features

• High Insulation Performance：Designed for high-voltage environments with oil-paper or SF₆ gas insulation to withstand operating overvoltage, lightning overvoltage, and DC bias magnetization.
• Special Winding Design：Split winding structure adapts to multi-bridge arm topology of converter valves while reducing harmonic impact on the power grid.
• Efficient Cooling System：Equipped with forced oil circulation directed cooling or forced air cooling systems to ensure stable heat dissipation under rated load for large-capacity operation.
• Strong Short-Circuit Resistance：Reinforced mechanical fixing structures in windings withstand short-circuit current impacts during system faults, reducing deformation risk.
