The variable frequency transformer rectifier is specifically designed to provide multiphase rectified power for medium and high-voltage frequency converters. Supported by DuPont Nomex® insulation, the rectifier is suitable for a wide range of medium to high voltage inverters, effectively filtering harmonics, protecting motors, dissipating heat, and preventing flames.
The product range includes 9-phase, 12-phase, 18-phase, and 27-phase rectifier frequency conversion transformers, available in both self-cooled and air-cooled types. These transformers are distinguished by their compact size, strong overload capacity, low partial discharge, high short-circuit resistance, flame retardancy, low noise, and 40% energy savings.
Technology Innovation
Reduced Harmonics: The secondary side uses an extended delta connection to reduce harmonic components in the input current.
Industry Pioneer: One of the earliest Chinese manufacturers to pass testing by the National Transformer Quality Supervision and Testing Center.
Scale Advantage: A large scale manufacturer of high-capacity frequency conversion transformers in China.
Advanced Secondary Design: Features a phase-shifted secondary side with a layered structure for the leads, an aesthetical design.
Product Features
1. NOMEX® Insulation: Provide class-C insulation with other benefits including heat-resistant, flame retardant, fireproof, and non-polluting.
2. 45° Cold-rolled Silicon Steel Sheet: The core material is made of high-quality cold-rolled silicon steel sheet carefully stacked at a full 45° angle.
3. Delta Connection: The secondary side adopts an extended delta connection to reduce the harmonic components of the input current.
4. Removable Assembly Structure: The partition plate can be removed or assembled .
5. High Mechanical Strength: High mechanical strength, strong short-circuit resistance, safe and reliable operation.
Core advantages
1. Advanced Process: The core adopts a through-core positioning structure with a multi-stage stepping process. Under various working conditions, the core has no lateral or longitudinal displacement.
2. Harmonic Filtering: Use multiple technologies to effectively suppress the harmonic content and filter the harmonics, extending the life of the motor.
3. Safe and Reliable: The winding adopts a variety of structural types, with strong short-circuit resistance and a dedicated air-cooling guide system with high heat dissipation efficiency.
4. High Efficiency and Energy Saving: strong overload capacity, energy saving of about 40%, low partial discharge and low noise.
5. Large Capacity and High-pulse Rectification: Diverse structures match various frequency conversion systems. The maximum product capacity can reach 9000kVA with 72-pulse rectification.
6. Tailor-Made: Self-owned factory customize on demand, flexible design and fast response.
