  • TRANSFORMER TANK CONSTRUCTION Filed Nov. 5, 1964 F/GU/PE g I vF/GLIRE/ United States Patent O 3,367,526 TRANSFORMER TANK CONSTRUCTION August Schmied, Weiz, Styria, Wilhelm Jan, Graz, Styria,
  • transformer tanks are built with a bell-shaped cover as in the case of inspection or repair works such a cover may be lifted by means of relatively simple lifting devices which are available also on the site.
  • This operative advantage of a so-called bell tank is however coupled with certain difliculties in transporting the transformer especially if great transformer units are to be transported for which units only a so-called bridge-girder truck is suitable. Owing to the transformer profile (dimensions) or to the weight of the transformer the transport of such units by means of a platform truck would not be possible.
  • the transformer tank In transporting a transformer using a bridge-girder truck the transformer tank is suspended between the truck girders by means of bracket bearings screwed or welded on the tank walls. This is practicable without any considerable additional provisions with tanks having a plain cover, owing to the longitudinal and cross stiffenings of the tank, which transmit the weight of the active transformer parts to the transport brackets.
  • transformers having a bell-shaped cover can be transported by means of a bridge-girder truck.
  • the object of this invention is a tank construction for transformers having a bell-shaped cover, which are to be transported by means of a bridge-girder truck.
  • stiffening frameworks surrounding both the upper bell-shaped tank part and the lower tank part on their circumferences, are tied together by means of tie rods provided preferably on places where the bracket bearings are screwed or welded on the upper framework for supporting the transformer on the two bridge girders of the transporting truck.
  • FIG. 1 shows a portion of a transformer tank made according to the present invention
  • FIG. 2 is a partial sectional view, taken along line II-II of FIG. 1;
  • FIG. 3 is an enlarged representation similar to FIG. 2, of the seal between the upper and lower tank portions.
  • numeral 1 indicates the lower tank part which has the shape of a flat trough on which the magnetic core of the transformer rests.
  • Numeral 4 indicates the upper tank part which has the shape of a bell applied to or placed above the active parts of the transformer. Both tank parts 1, 4 are provided with rigid flanges 13 between which a packing is interposed. With 2 and 5, respectively, stiffening frames are indicated which surround the lower and upper tank parts 1, 4, respectively, on its circumference. Cross-beams 3 are provided for strengthening the tank bottom which must take up the active weight of the transformer.
  • the weight of the active transformer part resting on the tank trough 1 is v transmitted to said transport bracket bearing 6 and therewith to a bridge girder 8 of the transporting truck by means of tie rods 7 passing through the lower and upper stiffening framework 2, 5.
  • tie rods 7 are provided with respective upper and lower fastening nuts 11, 12 for applying an additional pressure to the flanges 13.
  • the transformer tank design in accordance with the invention it is possible to transmit the main load (the weight of the active transformer parts) resting on the cross-beams 3, by means of the tie rods 7 directly to the transport bracket bearings 6 and thus to the bridge girders 8 of the truck.
  • the other tank parts are consequently largely relieved from strains and, above all, leakage of the tank oil is prevented which would be due to a decrease of the packing pressure on the flanges 13, resulting from transport strains.
  • a tank for large-size transformers adapted to be transported by Way of bridge-girder trucks comprising, in combination: lower and upper, separate tank portions, the former for supporting the operative elements of the transformer, the latter being bell-shaped and serving to cover said operative elements; lower and upper, substantially rigid flange means on adjoining respective peripheral parts of said tank portions, for interconnecting the latter; packing means interposed between said lower and said upper flange means, for preventing leakage of the oil Within the transformer; lower and upper stiffening frames rigid with and surrounding the respective lower and upper tank portions; bracket bearings attached to the sides of said upper fra-me, adapted to be engaged by bridge girders of a transporting truck; and tie rods passing through and interconnecting said lower and said upper frames, and also traversing said lower and said upper flange means, said tie rods serving for directly transmitting to said bracket bearings the vertical forces acting on said operative elements and on bottom of said lower tank portion during transportation of the transformer.
  • tie rods have screw threads at least along portions thereof, and further comprising tightening nutsapplied to said screw-thread portions in a flanking arrangement with said lower and said upper flange means and said lower frame, for tightening said packing means, while said upper frame is vertically spaced apart from said tightening nuts.
