Definitions

  • the invention relates to a method for producing a boiler, in particular for transformers, which has a cuboid or prismatic shape with housing walls made of cooling fin elements and a floor pan, and a boiler produced by the method.
  • a boiler is therefore provided around the electrical machine, the housing of which usually has four walls with cooling fin elements and a floor pan. The upper end is delimited by a frame on which a lid is attached to complete the boiler, e.g. screwed on.
  • the boiler receives the electrical machine and an oil filling, the latter, in the simplest embodiment of the boiler, conducts the heat generated by the electrical machine to the outer wall of the boiler, from where it is convectively released to the outside air.
  • the ribbed housing walls and the floor pan are welded together by hand or with the aid of simple devices. In this method, the handling is particularly the case
  • the invention comes in, which is based on the object of designing a method of the type described at the outset in such a way that not only the welding together of the individual parts, for example the cooling fin elements with the base pan, but also the welding together of the entire boiler is made considerably easier, such that a mechanized or auto- mati ⁇ overbased welding the seams with proportionate -. moderately low effort can be achieved.
  • the method according to the invention can also be used to improve the quality of the weld seams.
  • the boiler is assembled from individual wall parts, which are first prepared for itself, at least one housing wall, and a trough side wall are connected to form a wall portion which is completed it, with the other wall parts to a boiler housing .
  • the individual walls from a housing wall are expediently a tub side wall and a frame part formed, the joints between the individual parts can be provided with stiffeners.
  • the boiler produced by the method according to the invention is characterized in that the wall parts have a flange formed on the free end of the tub side wall and the frame part.
  • 1 is a cooling fin element made of a folded steel sheet in a spatial representation
  • FIG. 3 shows a wall part, which is composed of a cooling fin element according to FIG. 2, a tub side wall and a frame part, in a spatial representation,
  • Fig. 4 shows the structure of two wall parts and their positioning 'discrimination on a mounting surface
  • Fig. 6 shows the welded-together wall parts according to Fig. 5 with the welded-on tub floor.
  • Fig. 1-3 shows the manufacture of a wall part as it
  • O PI is used, for example, to manufacture a transformer tank.
  • a cooling fin element 1 is manufactured.
  • a band of sheet steel the width of the cooling fin element 1 is unwound from a band roll and provided with hollow cooling fins 4 in a folding press, the latter
  • the cooling fin element 1 produced in this way is stiffened on the side edges by welding a flat strip 8, 9, see FIG. 2, the cooling fins 4 being stiffened at their ends by two round bars 10, 11. If the length of the cooling fins 4 is large, further round rods can be welded on.
  • a complete wall part is shown, which is composed of the cooling fin element 1, a side wall 2 and a frame part 3.
  • the side wall 2 and the frame part 3, see FIG. 3, are welded to the cooling fin element 1 on their side walls after the ends 5 of the cooling fins 4 have first been welded.
  • a flange 12 or 13 is formed in each case and provided with holes 14, 15.
  • FIG. 4 shows the provision of wall parts 1, 2, 3 for welding to form a transformer tank.
  • the wall parts 1, 2, 3 are supported and positioned with the frame part 3 down on a mounting plate 16.
  • the positioning is carried out by means of positioning bolts 17 arranged in the mounting plate 16, onto which the flange 13 of the frame part 3 is inserted with the aid of some of the bores 15.
  • the holes 14 of the side wall 2 serve to insert a bracket 18 and thus hold two wall parts together. Since the cooling fin element 1 is stable due to the reinforcements 8-11, this also applies to the entire wall parts 1, 2, 3, so that they can be easily positioned.
  • FIG. 5 shows that four wall parts are combined to form a boiler housing, each wall part being positioned by the positioning bolts 17 and held together by the brackets 18.
  • the bent start and end edges 6, 7 serve to facilitate the positioning of the wall parts and to enable a good weld connection possibility between the cooling fin elements 1. Due to the inclined start and end edges 6, 7, unavoidable manufacturing tolerances can be easily compensated.
  • the edges 6, 7 lie one on top of the other, so that a precisely defined welding point is created on their circumference, which favors the creation of a flawless weld seam.
  • the edges 6, 7 are connected by spot welding, the welding points expediently being moved inwards to the root of the edges 6, 7 in order to prevent bending stresses in the circumferential weld seam of the edges 6, if internal pressure occurs. 7 to avoid or at least keep it small. Due to the spot welding on the edges 6, 7, the housing is fixed in its final shape and can be removed from the mounting plate 16 to carry out the final welding of the various welding seams.
  • Fig. 6 shows the welded transformer tank, which in addition to the housing of Fig. 5 one on the
  • the welding of the seams between the wall parts 1, 2, 3 and on the floor 19 can be carried out manually or by machine.
  • the way in which the transformer boiler is welded together is immaterial to the invention. It is essential that wall parts are first created in a stable, dimensionally stable design, the dimensional stability being achieved by producing the individual parts 1 - 3 by simultaneously creating well-weldable and defined welding points. This is particularly the case with the flat strips 8, 9 (FIG. 2), by means of which a defined welding part is created which favors the production of a perfect weld seam. In particular, an improvement of the welding point at the base points of the rib ends 5 is achieved.
  • the method described is not limited to the manufacture of transformer tanks. It can also be used in other areas where liquids have to be cooled by finned housing walls.

Abstract

Chaque paroi du boîtier est constituée d'un élément à ailettes de refroidissement (1), d'une partie de paroi (2) et d'un cadre (3) qui sont mutuellement soudés. L'élément à ailettes est renforcé par des bandes (8, 9) et des tringles (10, 11). Les différentes parois sont montées sur une plaque de montage (16) au moyen de vis (17) et maintenues entre elles par des étriers (18). Les éléments à ailettes sont solidarisés les uns aux autres au moyen de points de soudures sur leurs bords inclinés. Les éléments à ailettes constituent ainsi un boîtier sur lequel peuvent être appliqués les cordons de soudure horizontaux et verticaux définitifs. L'utilisation d'éléments préfabriqués pour le montage de boîtiers de transformateurs permet de diminuer la part de travail manuel car les soudures s'effectuent dans des emplacements précis et facilement accessibles.
