Help needed regarding rectifier devices

Thread Content

Our company has launched a new project involving electrolytic copper, and we now want to learn about it in advance. The voltage on the grid side of the rectifier transformers is 10 kV, with each unit consisting of 12 pulses. Two rectifier transformers operate in parallel, equivalent to a 24-pulse system; the on-load voltage regulation switch has 27 levels. The rectification unit uses a three-phase bridge rectifier circuit, with a rated DC voltage of 320 V and a rated DC current of 25 kA. If anyone has similar information regarding rectifier transformers and rectifier units, I would be very grateful if they could share it. In particular, I’m not quite clear about the communication parameters between these components, as well as the signals that the upper-level computer needs to monitor from the rectification unit. Thank you very much.
