Advanced Built-in Protection Systems
Our GAOHUI rectifier integrates a multi-layer safety suite for industrial reliability. Overcurrent protection triggers within 2 microseconds to prevent electrode short-circuit damage. Overvoltage clamping safeguards against grid transients. Overtemperature monitoring with automatic derating ensures continuous operation even in ambient heat spikes from nearby electrowinning tanks. Phase loss and input undervoltage alarms alert operators instantly via HMI or remote SCADA. All protections are fully configurable through the digital PID controller.
Target Industrial Applications
– Copper electrowinning (EW) from solvent extraction sx-ew circuits, producing LME-grade cathode copper.
– Copper scrap recycling and secondary copper refining, where stable DC is essential for impurity removal.
– Zinc electrowinning from sulfate solutions, requiring 12V-15V at 5000A for high-current-density operations.
– Precious metal electrorefining (gold, silver) where ripple-free current prevents dendritic growth.
– Hard anodizing of aluminum alloys for aerospace components, needing precise voltage ramping.
– Electrolytic copper foil production for PCB and battery anode applications.
