Rectifier transformers that provide power for electrochemical industrial rectifier devices are widely used in various fields, in order to improve the DC voltage waveform after rectification and the influence of higher harmonics of the rectifier device on

Product characteristics

  • Low loss
    reasonably select the working magnetic density of the core
    Reduce the working electrical density of each winding
    Reduce structural loss
  • Low partial discharge
    control dust control
    Rounded electrode
    Vacuum oiling
  • Multi-pulse
    single unit can be 12 pulse or 24 pulse, multiple units combined into 48~96 pulse
  • Small volume
    the modulator and two commutators share a common oil tank, and the transformer occupies less space, making it easy to maintain.

220kV double split transformer
In order to solve the problem of large-scale super capacity centralized power generation of new energy power stations, double split structure is adopted. Each phase of a double-split transformer consists of a high-voltage winding and two low-voltage winding with the same voltage and capacity. The double split transformer normally transmits electrical energy between the high and low voltage windings. Two low-voltage windings of the same voltage and capacity can be operated separately or in parallel to bear different loads. Mainly used in wind power, photovoltaic and other new energy power generation markets and large state-owned enterprises.
