Definitions

  • the invention relates to a method for producing a disc-shaped, curved magnetic coil, in particular for a system for accelerating and / or storing electrically charged particles such as electrons, the conductors of the coil to be produced having a convexly shaped outer side and a concave-shaped inner side
  • the winding core is thus arranged with a partially negative curvature and then fixed in its corresponding position.
  • the invention further relates to devices for performing this method.
  • a corresponding magnetic coil is e.g. from the publication "Fuji Electric Review", Vol. 19, No. 3, 1973, pages 112 to 118.
  • This coil which is wound from superconductors, is curved along a circular arc length with a predetermined radius and a predetermined arc (central) angle, so that it has a convex-shaped outer side and a concave-shaped inner side.
  • the magnetic coil the conductors of which are fixed in their geometrical position by struts between these sides, is intended to serve as a lifting magnet for the contact-free levitation of a vehicle along a roadway.
  • these windings In order to guarantee an unchanged position of the windings of these windings to be created from appropriate conductors, these windings must first be wound around a correspondingly shaped winding core and fastened to this. However, this poses the problem of winding with a negative radius of curvature in the region of the concave inner sides of such winding cores.
  • Magnets the windings of which have negative curvatures
  • a successive clamping of the conductor using special pressure elements such as single, fixed to the outside edge of a correspondingly shaped winding core clamps known.
  • the conductor pieces clamped with these elements must then be fixed, for example glued, piece by piece to the winding core or, if appropriate, to conductor windings already applied to these.
  • winding techniques of this type are very complex and time-consuming, in particular for the production of superconducting dipole magnets of storage volumes.
  • the object of the present invention is therefore to create a method with which a large-scale production of disk-shaped, curved magnet coils is made possible in a relatively simple manner, in particular superconducting conductors to be provided.
  • This object is achieved according to the invention for the method mentioned at the outset by first adding a shaped body of a predetermined shape to the winding core. so that a provisional winding body with only positive radii of curvature of its outer sides and at least approximately the same outer circumference as the winding core is formed. that the conductors are then wound around this winding body under tension, which are then attached only to the winding core of the winding body, and that after removal of the shaped body, the conductor parts thus exposed and facing the area of the concave inside of the winding core are pressed against this inside and fixed there .
  • the advantages associated with this embodiment of the method are to be seen in particular in the fact that the winding body composed of the winding core and the shaped body has only positive radii of curvature, so that the individual conductors can be wound around it without difficulty under tension.
  • the concave inside of the coil to be created is then obtained by forming the corresponding long side of the curved winding after removing the shaped body by pressing the conductors on this side against the concave inside of the winding core.
  • a coil with a negative curvature can thus be created without the need for a special, generally very complex fixation of the entire turns during the winding process.
  • the method according to the invention can advantageously be carried out with a device for which a lenticular fitting piece, which is to be positively attached to the concavely shaped inside of the winding core, is provided as the shaped body.
  • a lenticular fitting piece which is to be positively attached to the concavely shaped inside of the winding core.
  • Another device for carrying out the method according to the invention contains a composite molded body which has at least two molded parts adjacent to the strongly curved end pieces of the winding core and at least one connecting part extending between these molded parts, the transition from the convex outside of the winding core to the respective molded part of the Shaped body is a predetermined distance from the corresponding end piece of the winding core and a greater curvature of the molded parts is provided in predetermined areas. so that after creating the provisional winding around the winding body, removing the shaped body and pressing the thus free winding parts against the concave inside of the winding core, the winding parts previously in contact with the more curved regions of the molded parts are at least approximately at the strongly curved ends of the winding core. In this way, mutual movements of the conductors and thus uneven stretching can be kept to a minimum during the winding process.
  • FIG. 1 indicates the manufacture of a curved, disk-shaped magnetic coil with a device suitable for this purpose.
  • Figure 2 shows schematically a special embodiment of a corresponding magnetic coil.
  • FIGS. 3 and 4 schematically illustrate a further device for carrying out the method according to the invention during different process sections. Corresponding parts in the figures are provided with the same reference numerals.
  • a plan view of a planar winding core 2 can be seen schematically from FIG. 1, as can be provided, for example, for producing a planar dipole magnet coil for electron storage.
  • the winding of the coil is to be created with at least one flat, in particular superconducting conductor.
  • the winding core 2 which extends along a predetermined arc length b with an arc or curvature radius p, has a constant width of 2 x D.
  • the size D is the distance from the arc line b to the two concentrically curved long sides 3 and 4 of the winding core 2
  • This constant width of the winding core extends over an arc length ⁇ . ⁇ °. ⁇ / 180 °, where a ° is the centimeter or arc angle measured in degrees.
  • the front end pieces 5 and 6 of the winding core 2 are formed by semicircles with diameters of 2 ⁇ D each.
  • the convex-shaped outer side 4 to be wound is thus connected to the concave-shaped inner side 3 of the winding body 2 via these semicircles.
  • an approximately lenticular adapter 7 is positively attached to this concave-shaped inner side 3 of the winding core 2 as a shaped body, which has the height of the conductor to be wound and whose outer side 8 to be wound tangentially contacts the end pieces 5 and 6 of the winding core 2 .
  • This adapter thus has on the side facing the winding core 2 a radius of curvature of p - D over an arc length ( ⁇ / 180). a. (p - D).
  • This part of the fitting is followed by circular arcs on both sides with the radius of curvature D and the arc angle a.
  • the outside 8 of the fitting to be wound preferably has a radius of curvature + D and also an arc angle ⁇ .
  • the coil conductors 11 are now wound into a winding package of constant width under tension, the same distance between the individual conductor turns being maintained. Because the radii of curvature are always positive. is advantageously an absorption of at the radius of curvature D of the end-face end pieces 5 and 6 bent conductor 1 1 is not to be feared.
  • the fitting 7 can be reduced in size and removed. A subsequent pressing of the leno parts located in the area of the thus free concave inside 3 of the winding core 2 then takes place on this longitudinal side as if each winding individually lies against the winding core 2 with an adapted length.
  • the outside 8 of the fitting 7 to be wounded ensures that the conductor lengths in the individual turns before and after pressing on remain at least largely constant, thus avoiding compression or overstretching of the conductor.
  • the pressed-on conductor parts are denoted by 11 'and indicated by dashed lines. A loosening of the clamps holding the winding on the winding core is therefore not necessary. Since the adapters have exactly the height of the conductor of the turns, double disks can advantageously also be wound one after the other. Superconducting dipole magnetic coils are generally constructed from such double disks.
  • the shaped body in each case only comprises a single fitting 7 per disk-shaped winding and that the conductors abut one another in a form-fitting manner on the end pieces 5 and 6 of the winding core 2.
  • a conductor thinning can also be achieved at the front ends of the coil.
  • a partial winding 15, 15 ' is first built up around a central, curved winding core 2 using an approximately lenticular adapter 7.
  • Half-moon-shaped fits 18 and 19 are then positively attached to this created, partial curvature in the region of their front ends 15a and 15b.
  • This larger winding body is wound as for the first partial winding.
  • the larger partial winding enclosing the first partial winding 15, 15 'is designated 16, 16' in the figure.
  • further partial windings can then be created.
  • the exemplary embodiments were based on curved winding cores whose center or arc angles ⁇ are chosen to be less than 90 °.
  • the fitting pieces each have a radius of curvature on their outer side to be wound, which is due to the radius of curvature the arc length of the central winding core. whose width and arc angle is determined. If necessary, however, the outside of these adapters to be wound can also have a differently curved shape. The only requirement for this is that there are no negative radii of curvature and the length of the outside of the fitting to be wound is selected so that the conductor lengths in the individual turns before and after the pressing process are at least largely constant.
  • An embodiment of a corresponding shaped body is shown in Figure 3.
  • a planar winding core 20 can be seen schematically from this FIG. 3, which is to be provided with a winding according to the method according to the invention.
  • the winding core 20, which extends along a predetermined arc length b 'with an arc or curvature radius p', has a constant width of 2 x D 'between its two concentrically curved longitudinal sides 23 and 24.
  • the central or arc angle a ' have a value of 1 80 °.
  • the front end pieces 25 and 26 of the winding core 20 are formed by semicircles with diameters of 2 ⁇ D 'each.
  • a shaped body 28 that can be assembled from several pieces is added to the winding core 20 according to the invention.
  • This molded body comprises two outer molded parts 29 and 30 which are to be attached essentially to the convex outer side 24 in regions 32 and 33 adjacent to the end pieces 25 and 26. whereby they lie tangentially on the winding core 20 at transition points 35 and 36, respectively.
  • These outer molded parts 29 and 30 are assembled with a single or multi-part connecting part 37 (37a and 37b) extending between them on the side facing the concave inside 23 of the winding core 20 to form the molded body 28.
  • the connecting part 37 can be designed in any way on its inside 38 and, for example, lie against the inside 23 of the winding core 20.
  • a flat shape is assumed.
  • the molded body now forms, together with the winding core 20, a provisional winding body 39 with only positive radii of curvature on its outer sides, its outer circumference advantageously being at least approximately equal to the outer circumference of the winding core 20.
  • the transition points 35 and 36 between the winding core 20 and the outer mold parts 29 and 30 are advantageously at a predetermined distance e from the respective end pieces 25 and 26.
  • the molded parts 29 and 30 are advantageously designed such that they each have a more curved region 40 and 41 of their outer sides 42 and 43 at a predetermined location.
  • the position of these areas is determined by the fact that after the winding body 39 has been wound with a provisional winding 45, the winding parts 46 and 47 initially resting on these areas in the finally created curved winding are at least approximately at the areas of the strongly curved end pieces 25 and 26 of the winding core 20.
  • the winding deformed in this way is illustrated schematically in FIG. 4 as a top view and is designated 45 ′.
  • the winding is held in a form-fitting manner by the contact piece 52 on this inside due to a holding force K '.
  • the winding 45 After the winding 45 has been pressed on, it can then be solidified by means of a hardenable plastic. As is also indicated in FIG. 4 by arrowed lines 55, after removing the pressure piece 52, the conductor parts resting on the concave inside 23 of the winding core 20 can still be attached to this side, for example clamped, for example.
  • the molded body 28 with its molded parts 29 and 30 and the connecting part 37 can have exactly the height of the conductor of the turns to be created, so that double disks can be wound one after the other.
