Definitions

  • the invention relates to a superconductor protection unit for ensuring the heat generated by the sudden transition of superconductor windings provided to a superconductor transformer from the superconductor state to the normal state (quench) to be discharged without damaging the superconductor windings.
  • superconductivity When the temperature of a material is lowered below a certain value, the condition of completely zero electrical resistance is called superconductivity. In superconductor materials, when the temperature drops below a certain value, the material becomes a superconductor. An electric current can continue to flow through the superconductor material without receiving power from any source. Liquid nitrogen is often used to cool superconductor materials to the critical temperature at which they begin to show superconductivity. Today, superconductors are used in many applications such as health, military, and energy efficiency.
  • the present invention relates to a superconductor protection unit for eliminating the above- mentioned disadvantages and bringing new advantages to the related technical field.
  • An object of the invention is to provide a superconductor protection unit that allows the heat generated by the superconductor windings provided to a superconductor transformer to be discharged from the superconductor state (quench) without damaging the superconductor windings.
  • the present invention is a superconductor protection unit to discharge the heat generated by the sudden transition of superconductor windings from the superconductor state to the normal state (quench) provided to a superconductor transformer without damaging the superconductor windings in order to realize all the objects that will emerge from the abovementioned and the following detailed description.
  • a cylindrical block with high thermal conductivity in which superconductor windings are wound to be placed in the liquid nitrogen reservoir in the transformer a plurality of winding slots in which each superconductor winding is placed to limit the movement of the superconductor windings placed on the said cylindrical block, and a groove provided on the cylindrical block to prevent the formation of magnetic and electrical change dynamics on the cylindrical block.
  • a possible embodiment of the invention is characterized in that the cylindrical block is made of aluminum.
  • Another possible embodiment of the invention is characterized in that a single layer of kapton strip tape is provided between the cylindrical block and the superconductor windings in order not to weaken the thermal conductivity.
  • Figure 1 shows a frontal representative view of the superconductor protection unit.
  • Figure 2 shows a side representative view of the superconductor protection unit.
  • the invention relates to a superconductor protection unit (10) for ensuring that the heat generated by the sudden transition of superconductor windings (20) provided to a superconductor transformer from the superconductor state to the normal state (quench) is discharged without damaging the superconductor windings (20).
  • the superconductor contains at least one liquid nitrogen reservoir within the transformers.
  • a cylindrical block (100) with high thermal conductivity, in which superconductor windings (20) are wound, is placed in the liquid nitrogen reservoir.
  • Said cylindrical block (100) is made of aluminum.
  • the cylindrical block (100) includes a plurality of winding slots (110) for winding the superconductor windings (20). Said winding slots (110) ensure that the superconductor windings (20) are stopped regularly by limiting the movement of the superconductor windings depending on the vibration.
  • a groove (120) is provided on the cylindrical block (100) so that the superconductor windings (20) are not affected by magnetic and electrical change dynamics.
  • the groove (120) may be left empty in a possible embodiment of the invention.
  • an electrically insulating material can be placed in the groove. It is preferred to use the G-10 material as said electrically insulating material in a possible embodiment of the invention.
  • the groove (120) prevents the formation of eddy currents that will arise from the magnetic flux change on the cylindrical block (100) and will be formed by Lenz's law.
  • the heat generated due to the temperature in the event of an error must be discharged as quickly as possible.
  • the heat generated in the case of error is reduced to a few amperes due to the S-N passage of the superconductor through the superconductor winding (20).
  • the stabilizer layer provided on the superconductor winding (20) is activated in the meantime and allows the current passing through the superconductor to flow largely through itself.
  • the heat generated in the current state is largely due to the resistance of the stabilizer layer. A certain part of this heat is present in liquid nitrogen.
  • the increasing heat also increases the temperature of the superconductor winding (20). This increase in temperature is due to the increase in resistance.
  • the aluminum cylindrical block (100) allows the transfer of the heat formed on the superconductor winding (20) to both liquid nitrogen and itself, allowing the temperature increase to be limited more effectively. Thus, by limiting the heat formed on the superconductor winding (20), the deterioration of the superconductor windings (20) is prevented due to the increasing temperature.
  • a single layer of kapton tape was applied between the superconductor winding (20) and the cylindrical block (100) to avoid weakening the thermal conductivity.
