专利摘要:
Each wall of the casing is comprised of a cooling blade element (1), a wall portion (2) and a frame (3) which are welded to each other. The blade element is reinforced by strips (8, 9) and rods (10, 11). The different walls are mounted on a mounting plate (16) by means of a screw (17) and held in relation to each other (18). The blade elements are secured to each other by tack welding on their inclined edges. The blade elements form thereby a casing on which the final horizontal and vertical welding beads may be applied. The use of prefabricated elements for mounting transformer casings allows to reduce manual work since the weldings are effected in definite and readily accessible locations.

专利说明:

This invention relates to electrical engineering and can be used primarily in transformer designs.
The aim of the invention is to increase reliability.
FIG. 1 shows a cooling ribbed element of a folded sheet steel, general view; FIG. 2 shows a cooling ribbed element with attached stiffeners; in fig. 3 - tank wall, assembled from a cooling ribbed element, upper and lower frames, general view; in fig. 4 - assembly of two wall parts and their positioning on the mounting surface; in fig. 5 - assembly and positioning of four wall parts on the mounting surface; in fig. 6 - welded tank walls with welded bath bottom.
The tank has the shape of a rectangular parallelepiped or prism and contains walls, each of which consists of a ribbed element 1 and upper and lower frames 2 and 3. The ribbed element 1 is made with cooling ribs 4, the ends of which are flattened. Edges 6 and 7 of the ribbed element are made at an angle of 45. The stiffening elements in the form of flat strips 8 and 9 are welded to the upper and lower edges of the inner surface of the ribbed element 1, and the stiffening elements 10 and 11 in the form of round rods to the outer surface
The proposed tank is made as follows.
First, a cooling ribbing element 1 is made. Dp of this is unwinding a rolled steel roll into a roll equal to the width of the cooling ribbed element 1, and provided in a curving press with hollow cooling ribs 4, the end 5 of which is flattened. The edges 6 and 7 of the ribbed element are preferably folded at an angle of 45 to the plane of the tape.
The manufactured cooling ribbing element 1 is reinforced on the side edges by welding flat tapes 8 and 9 (Fig. 2), and the cooling ribs 4 are reinforced at their ends by means of round bars 10 and 11. If the length of the cooling fins 4 is large, then CAN. BUT weld the other round bars.
Each wall of the tank is collected from the cooling ribbed element 1,

top 2 and bottom 3 frames. The upper 2 and lower 3 frames are welded to the cooling ribbed element 1 on their side walls, after the ends 5 of the cooling fins 4 have been welded. At the free ends of the upper 2 and lower 3 frames, one flange 12 and 13 are provided with holes 14 and 15.
4 shows the preparation of the 2 and 3 walls for the connection of the transformer tank. The wall elements rest part of the frame 3 on the mounting panel.16 and position. The positioning is carried out by positioning fingers 17 placed in the mounting panel 17, onto which the flange 13 of the lower frame 3 is mounted with several holes 15. The holes 14 of the upper frame 2 serve to install the bracket 18 and, therefore, to join two walls. Since the cooling rib 5 element 1 is stable due to the stiffening elements 8-11, this also applies to all the elements 1, 2 and 3 of the wall, therefore, they can be easily positioned.
As shown in FIG. 5, the cell walls are integrated into the tank body, each wall being installed at a predetermined location by means of the positioning fingers 17 and connected by means of staples 18. The bent starting and ending edges 6 and 7 serve to facilitate the positioning i of the wall portions and make good welded joint of cooling ribbed elements 1. Due to the inclined starting and ending edges 6 and 7, the inevitable manufacturing tolerances can be compensated. The edges 6 and 7 are adjacent to each other, therefore, at their periphery a precisely defined welding spot is formed, which contributes to the creation of a quality weld without flaws.
If the walls of the tank are installed at a predetermined location and are joined, then edges 6 and 7 are joined by spot welding, and it is advisable to transfer the weld points inwards to the base of edges 6 and 7 so that when an internal pressure occurs, avoid or at least keep a slight bending appearance. of the stresses in the peripheral weld of the edges 6 and 7. Thanks to spot welding on the edges

6 and 7, the casing is fixed in its final form and can be removed from the mounting gangelle 16. to perform the final welding of various welds.
The finally welded transformer tank (FIG. 6) has, in addition to the housing shown in FIG. 5, welded to the flanges 12. upper frame 2, bottom 19.
Welding the seams between the elements 1, 2 and 3 of the wall and at the bottom 19 can be carried out manually or mechanized. First, the wall parts are created in a stable form with a constant shape, and when they are made from separate parts 1–3, the shape is achieved by simultaneously creating well-welded and definable welding points. This takes place primarily in flat tapes 8 and 9 (Fig. 2), due to which they create a specific welding spot that contributes to the manufacture of a weld without flaws. Special
an improvement in the weld area at the bottom ends of the 5 fins is achieved.

Invention Formula
The tank is mainly for transformers, which refers to the shape of a rectangular parallelepiped or prism with side walls, a base and a lid, each of the tank walls consisting of a cooling ribbed element, upper and lower frames, and stiffness elements in the form of flat ribbons on the inner surface of the cooling ribbed element, and on the outer surface of the surface, stiffening elements in the form of round rods connecting the ribs are different in that, in order to increase reliability, flat tapes are placed on the upper and lower edges The bottom of the cooling ribbed element at the joints with the upper and lower frames, the upper and lower frames being made with the flanges.
