This Siemens zinc electrolysis rectifier group, model 500 kA, manufactured in 2009, is a comprehensive electrical assembly designed for industrial applications. The system includes a 500 kA transformer, two rectifiers rated at DC 100 kA and 125 V each, four DC switches, a cooling group, and a control cubicle. The overall rectifier control is managed by a Simatic S7-300 PLC featuring a CPU317-2DP as the central processing unit.
The rectifier group has a rated power of 2x 16.78 MVA with OFAF cooling and is designed according to DIN EN 60076 standards, ensuring constant performance across all steps. The rated voltage ratio includes two TFKJ 7341 transformers with high voltage (HV) ratings of 6,000 V ± 5% across 5 steps and low voltage (LV) ratings of 238 V / 238 V. Additionally, it features two LFAJ 7031 interphase reactors at LV rated at 92 V.
Voltage and current specifications for the HV and LV windings are detailed, with HV currents ranging from approximately 1,538 A to 1,700 A and LV current at 28,783 A. The interphase reactor at LV supports 2x 92 V and 50,000 A.
The equipment is mounted on a metal base frame with visible wiring and connectors, indicating a robust industrial design. The transformer and electrical enclosures are painted green, with control boxes and pressure gauges installed. The presence of a large cylindrical tank labeled Siemens and industrial pump assemblies with stainless steel piping and electric motors further support the system's comprehensive setup. A cooling or ventilation unit with two large fans is included, secured on a wooden pallet.
The machinery appears clean, well-maintained, and intact, stored both indoors and outdoors on concrete surfaces and pallets, suggesting careful handling and preservation. Wooden crates labeled "Made in Germany" accompany the equipment, reflecting its origin. This rectifier group is suitable for buyers seeking a high-capacity, Siemens-manufactured zinc electrolysis system with detailed electrical and mechanical components included.
