  • the aluminum smelter 1 illustrated in figure 4 comprises a secondary electrical circuit 17 forming an inner loop, traversed by an electric current I3.
  • the use of electrical conductors of superconducting material to form the secondary circuit or circuits 16, 17 is interesting because of the length, of the order of two kilometers, of the secondary electrical circuits 16, 17.
  • the use of electrical conductors in superconducting material requires less voltage compared to that required by electrical conductors made of aluminum or copper.

  • the use of one or more turns in series to form the secondary electrical circuits 16, 17 of superconducting material has the advantage of reducing the magnetic fields in the path between the feed station 18 and the first and the second. last tank 2 electrolysis because it has a low intensity on this path (a single passage of the electrical conductor).

This makes it possible to circumvent the obstacles 19 present inside the aluminum smelter 1, for example a pillar, as is visible on the figure 10 .

  • the electrical conductors of superconducting material or secondary electrical circuits 16, 17 may be arranged under the electrolysis tanks 2. In particular, they can be buried. This arrangement is made possible by the small size of the electrical conductors of material superconducting on the one hand, and by the fact that they do not heat on the other hand. This provision would be difficult to achieve with electrical conductors made of aluminum or copper, because their size is greater at equal intensity, and because they heat and therefore need to be cooled (commonly in contact with the air and / or with specific cooling means).

  • they can not be placed under the electrolysis tanks 2, such as the secondary electrical circuits 16, 17 with electrical conductors of superconducting material, because they have a larger footprint and need to be cooled.
  • the secondary electrical circuits 16, 17 using electrical conductors of superconducting material may, however, be placed under the electrolysis tanks 2. Access to the electrolysis tanks 2 is thus not limited.
  • the electrical conductors of superconducting material may be contained partly inside a magnetic shield enclosure 20.
  • This enclosure 20 may be a metal tube, for example steel. It can significantly reduce the magnetic field outside of this magnetic shield. This thus makes it possible to create, in the places where this chamber 20 has been placed, passage zones, in particular of vehicles the operation of which would have been disturbed by the magnetic field emanating from the electrical conductors made of superconducting material. This makes it possible to reduce the cost of these vehicles (which must otherwise be equipped with protection).
  • This enclosure 20 may advantageously be placed around the electrical conductors of superconducting material located at the end of the line F, as illustrated on FIG. figure 6 .
  • the magnetic shield enclosure 20 may also be formed of superconducting material maintained below its critical temperature.
  • this enclosure of superconducting material forming a magnetic shield can be disposed as close as possible to the electrical conductors of superconducting material, inside the cryogenic envelope. The mass of superconducting material of the enclosure is minimized and the superconducting material of the enclosure is kept below its critical temperature without the need for another specific cooling system.
  • a protective enclosure 20 is not possible with conventional electrical conductors of the prior art made of aluminum, or even copper. These aluminum electrical conductors actually have a section of significant dimensions, of the order of 1 m by 1 m, against 25 cm in diameter for an electrical conductor of superconducting material. Above all, aluminum electrical conductors heat up in operation. The use of such a magnetic shield enclosure 20 would not allow a proper evacuation of the heat generated.
  • the electrical conductors of superconducting material have a mass per meter which can be twenty times lower than that of an aluminum electrical conductor for an equivalent intensity.
  • the cost of the supports of the electrical conductors in superconducting material is therefore lower and their installation is facilitated.
  • the main electrical circuit 15 of the aluminum smelter 1 may also comprise one or more electrical conductors of superconducting material.
  • the electrical connecting conductors 14 electrically connecting the rows F of the series to each other may be of superconducting material, as shown in FIG. figure 8 .
  • the electrical connecting conductors 13, connecting the ends of the series of electrolysis cells 2 to the poles of the feed station 12 of the main circuit 15, may also be of superconducting material, as shown in FIG. figure 9 .
  • the electrical connecting conductors 14 connecting two rows F measure from 30m to 150m depending on whether the two lines F they connect are in the same building or in two separate buildings for reasons of magnetic interaction between these two lines.
  • the electrical connecting leads 13 connecting the ends of the series to the poles of the power station 12 generally measure from 20m to 1 km depending on the positioning of this station 12 supply. Because of these lengths, it will be readily understood that the use of electrical conductors of superconducting material at these locations can achieve energy savings.
