Definitions

  • the invention relates to a transformer, a Converter or a choke for medium to large outputs according to the preamble of claim 1 and on a Method for producing such a component.
  • Such inductive components are principally from the EP 0 522 475 B1 is known. However, the windings are there only designed for much lower performance.
  • EP 0 522 475 B1 discloses an inductive component, in particular a transformer with multiple windings.
  • Each slice winding consists of a relatively thin one flat metal plate, in which a spiral revolving Slot is introduced. Through the slot is the metal plate to a flat winding with several in one level adjacent turns.
  • the individual winding disks insulating layers are stacked on top of each other stacked and via side connections contacted; the internal winding connections can be connected via metal pins that can be inserted later become.
  • the disc windings are insulated over the Intermediate layers due to pressure and temperature baked electrically insulated winding package on all sides. The Heat dissipation occurs exclusively with this inductive component over the surface of the winding package.
  • the object of the invention is a transformer, a Converter or a choke according to the preamble of the claim 1 designed so that he or she for medium until large powers of around 100 to 3000 A can be used; this results in particular in the demand for an effective one Heat dissipation along the entire surface of the used Disc windings. At the same time, the assembly effort for the transformer, converter or the throttle should be kept as small as possible. It is further Object of the invention, a method for producing a to specify such a static machine.
  • the invention solves this problem by the characterizing Features of claim 1 and 23.
  • Disc windings made of a few mm thick metal plates the possibility of making the windings more powerful to manufacture inductive components fully automatically without their individual turns laboriously by hand to a particular one Shape must be adjusted.
  • the individual disc windings can be manufactured, also externally manufactured, and then be kept until assembly in a warehouse from which they can be accessed as needed.
  • the disc windings are then only still electrically contact, which is why the ends of the equip individual disk windings with appropriate means are. At least the contacting of the inside Connections are made during or after layering the windings, in any case, before inserting one Magnetic core, as long as the connections for the assembly personnel are still easily accessible.
  • the metal plate according to claim 2 should consist of an aluminum or according to claim 3 of a copper alloy. Both materials have good electrical conductivity and can easily be used even with thicker sheet metal to edit.
  • the disc winding must be electrically insulated (claim 6) in order to avoid cross currents when touching.
  • the disk windings according to claim 7 at the end contacting eyelets exhibit. It is possible to use the disc windings according to claim 8 to several in series or in parallel to switch without this being any customizable Bracket required. Align by appropriate arrangement of the eyelets both when the disc windings are parallel as well as if they are to be connected in series.
  • the individual disc windings are contacted according to the teaching of claim 9 about screw connections or according to claim 10 via electrically contacting push buttons, as they are known in principle for contacting batteries are; Claim 11 sees the contacting of the turns brazed flanges.
  • the spacer elements according to the teaching of claim 12 for the separation of Windings of the individual disk windings at the same time be used to separate adjacent disc windings. This is achieved if the spacer elements according to claim 13 z.
  • B the shape of pins with end flanges or have a circumferential collar, the Grip the pins between the adjacent turns and the Flanges or the circumferential collar the individual disc windings keep your distance.
  • the pins could advantageously as screws according to claim 14 be carried out in the corresponding threaded holes Screw in windings or in through holes of the windings and plug them in there with nuts are holding.
  • the spacer elements are according to claim 15 in the Slots or in separate recesses in the disk windings held. They can be seen on the surface of the Arrange the disk windings in a distributed manner and hold the disk windings at a distance without the air circulation between the Noticeably affect disc windings. With bracket the spacer elements in the slots ensure them at the same time also for a separation of the individual turns of the Disc windings.
  • the spacer elements can also into the slots or recesses of two adjacent disc windings intervene and so according to claim 16 simultaneously Separate two disc windings and align them against each other.
  • the disk windings as claimed Align 17 over insulating rods, the insulating rods the windings can be used simultaneously to separate the individual disk windings.
  • the insulating rods By during assembly on the insulating rods on pluggable insulating washers or leave insulation pipes according to claim 18 keep the individual disc windings at a distance.
  • the insulating rods can according to claim 19 via locking washers permanently in the assembled disc winding block be fixed.
  • the insulating rods can advantageously as claimed in claim 20
  • Metal rods or metal pipes are formed, which face the outside are electrically insulated or in insulating sockets grasp in the windings.
  • the neighboring ones can be used to accommodate the spacer elements Windings of the disk windings according to claim 21 with one another facing recesses. It does it possible, the pins used as spacers relative large volume and therefore easy to handle. In advantageous Ways are the edges of the recesses for the pins to break according to claim 22. Theoretical considerations show that on sharp edges when loading the winding turns high field strengths occur with supply voltages and
  • the method according to the invention for producing disc windings for medium-sized transformers, converters or chokes to great performance consists in cutting according to claim 23 the disc windings made of flat, thick-walled metal plates, being in the metal plates by certain machining processes one each following the winding contour Slot is introduced.
  • the electrical insulation of the disc winding is said to Claim 24 preferably produced by a vortex sintering process become.
  • At least the internal connections of the disc windings be contacted according to claim 25 while they are still are accessible.
  • disc winding shown in the right part of Figure 1 it is a winding, like it on one rectangular core can be put on; their turns 1 to 4 run around a in the form of a rectangular spiral common axis.
  • the winding is coated on all sides electrically isolated.
  • the inner winding 1 and the outer winding 4 are widened at their ends and with Provided means for electrical contacting.
  • This means are formed in the drawing as eyelets 5 and 6, which on a straight line through the longitudinal axis of the disk winding.
  • eyelets 5 and 6 which on a straight line through the longitudinal axis of the disk winding.
  • FIG. 4 are several to build an electrical machine Arrange disc windings 7 to 11 one above the other in alignment and on a common, not shown in the drawing To put on the core.
  • the disc windings are theirs Parallel connection to several with the same winding direction and to connect them in series to several with different Layering the winding sense of their windings, to separate them and to connect them electrically. These connections are shown in the drawing for reasons of clarity not shown.
  • the contact is made via open or closed ends embedded in the turns Eyelets preferably with screw connections. The However, contacts can also be made in an advantageous manner electrically contacting push buttons or soldering become.
  • Each disc winding consists of one or more turns, each disc winding also consisting of several one above the other arranged and at least at their ends electrically connected thinner sheets that may not be formed must be separated from each other.
