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.
