The phase-shifting rectifier transformer is a power transformer for multi-pulse rectification equipment, which plays the role of isolation, phase shifting, and voltage transformation. It is widely used in high-voltage frequency converters and high-power rectification systems to realize multi-pulse rectification output and multiple technologies: The primary and secondary voltages have different phase differences through the Yanbian triangular phase-shifting connection group to reduce the harmonic G wave N, suppress harmonic pollution, reduce the DC ripple coefficient, and the AC side harmonics are also greatly reduced.

• Stable electrical performance: Combined with the characteristics of the industry, the scientific electrical and structural design ensures excellent electrical performance and meets the precise requirements of the multi-pulse rectification system for the phase-shifting angle and voltage amplitude of the phase-shifting transformer;
  High degree of dynamic stability: The high and low voltage windings of the product adopt multi-stage continuous structure or integral resin casting, which has high mechanical strength and strong anti-burst ability, and can meet the extremely harsh load environment;
  Good thermal stability: the simulation calculation optimizes the temperature rise of the heating part and the hottest point, leaving sufficient margin for temperature rise, and adopts the multi-step oblique seam design of oriented silicon steel, which effectively reduces no-load loss, no-load current and noise;
  Strong overload capacity: strong overload and overvoltage capacity, can operate safely for a long time under rated load conditions, fully consider the load characteristics, and can meet overload requirements in terms of temperature rise, insulation performance and other aspects;
  Excellent structural design: The air duct design is reasonable to reduce the ventilation resistance, equipped with a special cross-flow fan to ensure efficient ventilation and heat dissipation, the electrical connection is convenient and reliable, and the maintenance is simple. It adopts “three-proof” treatment and has a beautiful appearance.
