Sodium Hypochlorite Power Supply For Membrane Electrolysis Up To 100kA 1000V
Application
This is high power thyristor rectifier system used for Caustic Soda Rectifier for Membrane Electrolysis Up to 100kA 1000V.
Rectifier System Diagram for the Chlor-Alkali Industry
The rectifier system is composed of input high voltage switchgear, voltage regulating transformer for on load tap changer(OLTC), rectifier transformer, rectifier, DC switch, cooling water heat exchanger, power factor & harmonic compensation facility.
To get higher power factor and lower ripple, 12 pulse configuration is commonly adopted.
The system circuit diagram and system block diagram are shown here.
