Definitions

  • the invention relates to a coil for an electrical apparatus or an electrical machine, in particular for a physical high-current system, with at least one conductor rod made of a highly conductive material and an insulating layer enveloping it, and to a method for producing such a coil.
  • a coil is e.g. known from the Brown, Boveri Mitanderen 1959, pages 330 to 332.
  • Such coils are used, for example, for synchrotrons and similar large-scale physical systems.
  • a constantly repeating, very steep current rise and fall is required, which is of the order of many kilo-amperes per second.
  • These steep current rise and fall processes lead to correspondingly high forces acting on the coils, especially in large plasma-physical systems in interaction with the fields of neighboring coils.
  • the coils out a good conductive material and such materials usually have a low strength, it is necessary to provide very complex support structures for the coil to absorb the high forces that occur.
  • the conductor bar consists of a composite material
  • the one component of the conductor bar consisting of a material with high conductivity but less strength and the second component of the conductor bar made of a curable, highly conductive material consists.
  • the curing process is expediently carried out by heating the coil to temperatures between 400 ° and 500 ° C.
  • a material is provided, 'the strength of which is essentially maintained when heated to a temperature of 400 ° to 500 ° C. In this way it is achieved that, in contrast to the use of copper as the first component of the conductor, a reduction in the strength can hardly occur with the specified heating.
  • Copper zircon is expediently used as the material for the first component of the conductor bar.
  • the zirconium content can be so large that the first component can also be hardened.
  • the first component then has a reduced conductivity.
  • the zirconium content can be between 0.1% and 0.4%.
  • copper cobalt beryllium serves as the material for the second component of the conductor bar.
  • this winding component hardens, it has a strength of the order of 1000 N / mmz.
  • a particular advantage of such a composite conductor is good processability in the soft state, i.e. the manufacture of the coil presents no difficulty.
  • the two materials mentioned have approximately the same thermal expansion coefficient, so that bending of the conductor rod - in contrast to a steel-reinforced copper conductor rod - cannot occur due to thermal effects. Curing takes place only after the windings have been completed. Fragile coils then have high mechanical strength, which means that significant savings can be made in relation to the supports. For a given space, this arrangement can accommodate an optimal number of ampere turns.
  • the two components are strips which are connected to one another by rolling or by plating.
  • the two components of the conductor bar are strips which are connected to one another by soldering.
  • the composite conductor can expediently be solidified by rolling after the soldering process has taken place.
  • the conductor bar is first brought into the final shape and then the second conductor bar component is cured at a temperature between 400 ° and 500 ° C. After curing, the insulation is applied to the winding. The insulation is expediently applied before bending and impregnation is carried out after curing.
  • the curing process takes place in a vacuum or under a protective gas.
  • the conductor bar consists of a first component 1 and a second component 2, which are each designed as metal strips which are made of copper zircon or copper cobalt beryllium.
  • the shape of the coil can be circular, spiral or rectangular or square.
