Traction Rectifier Transformers
Rated capacity: 800 to 4400 kVA; Voltage class: 10 kV and 35 kV; Rectifier pulse number: 12-pulse and 24-pulse. Compared with 12-pulse rectifier circuits, 24-pulse rectifier circuits can reduce the harmonic pollution of the power grid by 50%, and no filtering equipment is needed at this location. It is suitable for power supply systems of urban subways and rail transit.
Excitation Rectifier Transformers
Rated capacity: 315 to 3000 × 3 kVA; Voltage class: 10 kV, 13.8 kV, 15.75 kV, 20 kV and 22 kV. It is usually designed with a single-phase structure, high-voltage phase-isolated enclosed busbar input and shielding between high-voltage coils. It is suitable for static excitation systems of hydropower plants and thermal power plants.
General-Purpose Rectifier Transformers
Rated capacity: 315 to 4000 kVA; Voltage class: 10 kV and 35 kV. It is suitable for rectifier systems of general industrial and mining enterprises.
H-Bridge Rectifier Transformers
Rated capacity: 315 to 2500 kVA; Voltage class: 3 kV and 6 kV. Each phase can be composed of 3 to 9 windings, which can be combined in pairs through phase-shifting connection to form an H-bridge rectifier. It is suitable for AC-DC variable frequency power supply systems of motors.
Three-Phase Five-Leg Rectifier Transformers
Rated capacity: 30 to 2500 kVA; Voltage class: 10 kV and 35 kV. It is used in double-delta rectifier circuits, which can eliminate balance reactors and reduce the impact of voltage-stabilizing current. It also reduces the transportation height. It is suitable for transformers with limited installation space or transformers used in delta rectifier systems.
Metallurgical Electric Furnace Transformers
Rated current: Less than 20,000 A; Voltage class: 10 kV and 35 kV; Equipped with an off-circuit tap changer. It is suitable for high-current electric furnace power supply systems in the metallurgical industry.
Marine and Offshore Platform Transformers
Rated capacity: 30 to 10,000 kVA; Voltage class: 0.38 kV and 35 kV; Certified by China Classification Society (CCS) and holds the CCS Type Approval Certificate for Marine Products. It is suitable for power supply systems on ships and offshore drilling platforms.
