Product Details

800A 80V Electrolysis transformer rectifier for chlorine generation by seawater and brine electrolysis

1. Application

The rectifiers(DC Power Supplies) are widely used for waste water treatment by electrolysis process, seawater desalination, Ballast water treatments, Sodium Hypochlorite generation from seawater or brine(Electrochlorination) , applied in water disinfection in industries, miniciplalities, residential colonies, schools and other water bodies, ballast water treatment; sea water treatment for industries using seawater for cooling system such as in cooled power plants, petrochemical industies, LNG terminals, desalination facilities & other coastal industries. 

2. Transformer rectifier working principle

After the AC power of the power grid is regulated by the rectifier transformer, it is rectified and regulated by the thyristor rectifier circuit. The control system realizes the measurement sampling, internal calculation, trigger control, protection, communication and other functions of the system, and realizes the stable DC output. 

Generally, there are two types of rectifying circuit: three-phase bridge and double star circuits. Select the appropriate circuit form according to the output parameters to realize the optimization of the system.

The system composition is like below:
