KGHS-6DD (12DD)-PLC KGHS-6DD (12DD)-PLC Series SCR Electrolytic Rectifier

KGHS-6DD (12DD)-PLC KGHS-6DD (12DD)-PLC Series SCR Electrolytic Rectifier

Description
KGHS series SCR electrolytic rectifiers adopt thyristor rectification technology. As a dedicated thyristor rectifier, it is mainly used for electrochemical purposes, like nonferrous metal electrolysis refining (copper, zinc, nickel, lithium, lead, etc.), copper foil electrolysis, aluminum foil electrolysis, rare earth electrolysis, saline solution electrolysis, chemical electrolysis, etc.

Main Technical Features
1. This electrolytic thyristor rectifier adopts DSP for digital control.
2. Double channels are available for hot spare, which makes the rectifier switch without stop and disturbing.
3. This electrolytic rectifier adopts thyristor 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 can carry out 9 to 27 grade on-load voltage regulation (coarse adjustment) and transformer secondary side thyristor regulates phase shifting voltage (accurate adjustment).
4. Local control and remote control can be converted mutually. KGHS series electrolytic thyristor rectifiers can choose constant current or constant voltage operation mode.
5. The rectifier transformer and SCR electrolytic rectifier in the main circuit adopts cophase inverse parallel connection process structure technology, which greatly reduces eddy current loss of accessories.
6. It uses CAN BUS, PROFIBUS, INDUSTRY ETHERNET, RS485 and RS232 optical fiber for communication.
7. With PLC colorful touch screen, the operation interface is flexible and has a good vision. It can timely record all kinds of parameters and historical curves of electrolytic thyristor rectifier’s operation.
