Thyristor electrolytic rectifiers (SCR electrolytic rectifiers) adopt SCR rectifier technology. It provides DSP digital control. Double channels are available for hot spare, making the rectifier switch without stop and disturbing. It adopts SCR 6 pulse rectification, 12 pulse rectification and 24 pulse rectification. There are high voltage 6KV, 10KV, 20KV and 35KV incoming line rectifiers. The rectifier transformer of this thyristor electrolytic rectifier or SCR electrolytic rectifier can carry out 9 to 27 on-load voltage regulation (coarse adjustment) and secondary side SCR regulates phase shifting voltage (accurate adjustment). Adopting cophase inverse parallel connection process structure technology, the rectifier transformer and SCR electrolytic rectifier in the main circuit greatly reduces eddy current loss of accessories. As a special thyristor rectifier, KGHS series thyristor electrolytic rectifier is mainly used in electrochemistry, such as nonferrous metal electrolysis refining (copper, zinc, nickel, lithium, lead, etc.), copper electrolysis, aluminum electrolysis, rare earth electrolysis, saline solution electrolysis, chemical electrolysis, etc.
