Electrolytic Rectifier Transformer
Voltage Regulating Rectifier Transformer for Chlor-alkali Industry

At present, the voltage regulating rectifier transformer used in chlor-alkali industry mostly uses 35kV-110kV power supply, and the annual output of a single series is 300,000-400,000 tons.When the regulating transformer and rectifier transformer share the same oil tank, the forced oil-air cooling are often used, and the self-cooling method is also used.

Self-coupling voltage regulation is adopted for the secondary voltage regulation of the voltage regulating transformer. Generally, it is continuous voltage regulation, and the number of stages is mostly 27. On-load tap changer is mostly made by domestic companies. The primary side of the rectifier transformer is connected with the secondary side of the voltage regulating transformer through the lead wire inside the oil tank.

The phase shift angle of the primary side of the rectifier transformer is calculated according to the total pulse number of 12N . The single unit group forms 12 pulse waves, and the phase shift angle difference within the single unit group is 30 ° configuration.The valve side adopts the bridge in-phase inverse parallel structure. The rectifier cabinet adopts silicon control.
