Application Industry:  Electrolytic copper foil industry

Electrolytic copper foil refers to copper material as the main raw material, using electrolytic copper foil production. Dissolve copper material by copper sulfate solution, then in electrolytic equipment, copper sulfate solution by direct current electrodeposition and made the original foil, again carries on the coarsening, curing, heat resistant, corrosion resistant layer, prevent oxidation layer surface treatment, such as lithium electricity copper foil axial-flow compressor.in order main surface oxidation treatment, finally made after cutting, testing the finished product.

During electrolysis, cations in the electrolyte migrate to the cathode and electrons are reduced at the anode. The anion runs to the anode and loses electrons to be oxidized. Two electrodes were connected in copper sulfate solution and direct current was applied. At this point, copper and hydrogen will be found to precipitate from the plate connected to the cathode of the power supply. If it is a copper anode, copper dissolution and oxygen precipitation occur simultaneously.

The module of the synchronous rectifier high-frequency switching power supply is installed in the parallel cabinet, and is connected with the cathode and anode bus of the foil generator through the output of the bus. Clean appearance, compact structure. High power conversion efficiency, reduce customer use cost. Power supply adopts N + 1 backup mode, which can realize thermal maintenance of the whole machine and ensure continuous production by customers.

(1) Cabinet structure: switching power supply cabinet adopts frame combination vertical structure, each sub-unit superimposed, with sufficient mechanical strength, front and back panels are open type, both sides of the removable sealing plate, easy to user maintenance and inspection.

(2) Host composition: two cabinets are placed diagonally. Each 20KA/7V cabinet is composed of 8 sub-units in parallel, each sub-unit is 3000A/7V, and the cabinet is placed in two columns and four layers.

(3) Overall size: W800mm *D1200mm *H1250mm, see the outline diagram of rectifier power supply in the attachment.

(4) OUTPUT mode of DC busbar: output at the top of the host. Each cabinet uses four 200*25 pure aluminum bars at each pole.
