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
