Scope of Supply

The composition of electrowinning power system is below:

For electrowinning, the system is composed of below parts:

• Three phase oil cooling transformer: include main transformer and voltage regulator with tap changer for voltage regulation at primary.

• SCR rectifier: 6 pulse or 12 pulses SCR rectifier. Each SCR is series connected with fast-acting fuse to protection SCRs.

• Controller system: DSP based self developed micro controller, including SCR trigger, signal sampling and handling , data storage, PID operation, logic control and communication etc. 

• DC output current measurement unit, high current Hall sensor

• Output remote control by Ethernet communication bus or RS485.

• Water chiller: provide qualified water to cool the power supply.

• Connecting bus between the transformer and rectifier
  

• Complete documentation in paper and electronic form
