Use Scenarios
Multi-pulse Rectification for Electrolysis Production
This three-split rectifying transformer, a professional oil immersed regulating rectifier transformer, serves as core power equipment for electrolytic workshops. The transformer rectifier adopts three independent split secondary windings to realize multi-pulse rectification, effectively suppressing harmonic interference on the public power grid. It maintains stable DC output under continuous heavy load, perfectly matching the long-cycle working conditions of non-ferrous metal electrolysis, brine electrolysis and hydrogen production. As an experienced rectifier transformer supplier, we tailor voltage and capacity parameters to fit different electrolytic cell requirements.
Power Supply for Non-ferrous Metal Smelting
Non-ferrous smelting plants face fluctuating heavy loads and harsh on-site environments. Our three-split transformer rectifier features strong short-circuit resistance and reliable oil cooling system. The split winding design ensures each winding operates independently; failure of one branch will not shut down the whole system, improving production continuity. The adjustable voltage function adapts to different smelting stages, reducing energy consumption and lowering the overall operating cost of the metallurgical plant.
Electrochemical & New Energy Industrial Projects
For electrochemical processing and green hydrogen projects, stable and controllable DC power is essential. This rectifying transformer delivers precise voltage regulation and low harmonic distortion. The robust grey painted steel tank can withstand high temperature and dust in industrial workshops. We support full OEM customization on dimensions and electrical parameters, which makes us a trusted rectifier transformer supplier for global new energy industrial investors.
The three split transformer rectifier is a special oil immersed regulating rectifier transformer whose low-voltage side is divided into three electrically isolated windings. It is mainly used for multi-pulse rectification systems to reduce grid harmonics and supply stable DC power for electrolysis, metallurgy and hydrogen production.
The triple-split structure realizes independent power output of three groups of windings. It greatly suppresses harmonic pollution to the power grid, improves power factor, and one winding fault will not cause full equipment shutdown. Compared with conventional rectifying transformer, it has better load balance performance for multi-rectifier units.
