Definitions

  • the invention relates to a transformer or a Throttle according to the preamble of claim 1 and on a method of manufacturing a transformer or a Throttle.
  • a transformer or a Throttle Such a transformer or such Chokes are known from EP 0 309 690 B1.
  • a transformer or a choke the core of which from yoke packages and windings arranged between them load-bearing thigh packages.
  • On the yoke packages are Clamping plates placed from the outside, parallel over the sides tension rods led to the legs are to be braced. The constructive effort for the mutual determination of the Core components are significant.
  • the clamping plates are common with the end faces of the yoke plates through across Weld seams running along the longitudinal axis of the yoke plates are defined.
  • the object of the invention is a transformer or Inductor according to the preamble of claim 1 in which or on the constructively complex clamping plates and their difficult determination by means of several Drawbars can be dispensed with.
  • the invention solves this problem by the characterizing Features of claim 1.
  • the particular advantage of transformer according to the invention or the inventive Throttle can be seen in the fact that in addition to the saving of constructive elaborate clamping plates and the avoidance of individually tightenable tie rods when welding the construction welding seams are drawn over the yoke plates, which the Fix yoke plates against each other.
  • the installation volume of the transformer according to the invention or of the invention Choke smaller than with a transformer or a choke, the core components of which are external Tension rods are clamped.
  • Claims 11 and 12 include a method for producing the transformer according to the invention or the throttle according to the invention.
  • the invention is based on one in the drawing illustrated embodiment for a three-phase Throttle explained in more detail. What a connection in this context three-phase choke applies, applies mutatis mutandis to others Chokes and with the exception of any information on air gaps also for transformers.
  • the drawing shows the essential components of a three-phase Throttle. These consist of a yoke package 1, one Core package 2 and the windings 3.1 to 3.3, which on the Legs 2.1 to 2.3 of the core package 2 and put there to be determined.
  • the yoke package 1 and the core package 2 exist from a variety of layered sheets in the shape of an I or an E.
  • the arrangement can also be such that the core of two yoke packs with leg packs in between is formed as dotted in the drawing Lines 2.0 is indicated in the core package.
  • Yoke package 1 and the legs 2.1 to 2.3 of the core package 2 are air gap inserts to form an air gap of predetermined thickness 4.1 to 4.3.
  • the finished choke is on the bottom with devices for mounting on one to provide any installation location.
  • the choke according to the invention is manufactured as follows: First, the yoke package 1 with four welding tabs 5.1 to 5.4. These welding tabs consist of U-shaped sheets cut out by bending their Form an L in the profile on the same side and that against the end faces when the throttle is fully installed the yoke plates and the corresponding parts of the Lay core sheets. The common yokes of the welding tabs lay on the broad sides of the outer leg plates the outer legs 2.1 and 2.3 and the outer yoke plates of the yoke package 1 and the corresponding part of the Core package 2. In a first welding process, the Welding tabs 5.1 to 5.4 welded to the yoke package 1. For this purpose, the legs of the welding tabs on the tongues protruding from the yoke packet 1 side, of which only tongues 5.21 and 5.31 of the two in the drawing Welding tabs 5.2 and 5.3 can be seen.
  • each footplate consists of an S-shaped sheet metal strip, one of which Leg 6.11 or 6.21 with recesses 6.12 or 6.22 for Provide recording of fasteners, not shown is.
  • the respective other leg 6.13 or 6.23 has recesses 6.14 or 6.24 provided for receiving the tongues serve at the free ends of the welding tabs 5.1 to 5.4. Of these tongues, only the tongues are in the drawing 5.22 to 5.42 can be seen.
  • the two foot plates 6.1 and 6.2 with further, wider slots 6.15 and 6.25 provided, on the edges of the sheets of the core package with Weld seams are to be defined.
  • the production of the Transformer completed so far that what is not of interest here Connect the windings to those provided Terminals can be made.
  • the tongues protruding in the base plates are usually standing down over the legs 6.13, 6.23 of the foot plates in front. Become more or thicker to create larger air gaps Air gap inserts used, so the tongues protrude less far through the foot plates or close with them flush. The tongues thus cause a limited adjustment the height of transformers and chokes to each present circumstances.
  • the welding tabs are mirror-symmetrical for universal use executed. Their yokes are so long that they are in the specified manner with the sheets of the yoke stack and have the foot plates butt welded. There where the thighs the L-shaped welding tabs from the yokes of the welding tabs protrude are the yokes with notches 5.13 to 5.43 provided. The depth of these incisions is of the order of magnitude one or a few mm. The cut edges of the incisions converge in an arc at the bottom of the incisions. The purpose of the incisions is to tear the thighs to avoid when bending.
  • the manufacture of the transformer according to the invention or Choke according to the invention occurs in several on top of each other following work steps; the transformer or the But throttle does not leave the respective workplace, like it does when using tie rods to set the individual core components is required. Reduce it the manufacturing costs in addition to saving the previously required clamping elements and the assembly costs not irrelevant.
