Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a transformer support bar structure and an installation method. Background Art

[0002] As an important power equipment, transformer plays a vital role in power transmission and distribution systems. In order to ensure the stable operation of the transformer, the problem of heat loss inside it must be effectively solved. For this reason, a support structure is usually set inside the transformer during the casting process, and the corresponding support structure is taken out after the casting is completed to form a heat dissipation channel.

[0003] The traditional transformer support bar structure usually has several positioning holes evenly opened on the upper and lower positioning rings, and multiple columnar support bars are inserted into these positioning holes. The advantage of this design is that it is relatively simple to manufacture and install, but the disadvantage is that in the subsequent pouring process, the channel formed by the support bar is small, the heat dissipation effect is poor, which is not conducive to the effective dissipation of heat inside the transformer.

[0004] Based on this, there is an urgent need for a transformer support bar structure and an installation method that can effectively improve the heat dissipation effect of the transformer. Summary of the invention

[0005] One of the purposes of the present invention is to provide a transformer support bar structure and an installation method, which can effectively improve the heat dissipation effect of the transformer.

[0006] In order to achieve the above object, a transformer support bar structure is provided, comprising an upper positioning ring, a lower positioning ring, and a support bar assembly arranged between the upper positioning ring and the lower positioning ring; the support bar assembly comprises a plurality of columnar support bars;

[0007] The upper positioning ring and the lower positioning ring are both provided with a plurality of long strip holes for the support bar components to be inserted.

[0008] Technical principle and effect of this scheme: In this scheme, the upper positioning ring and the lower positioning ring are positioned and fixed by support rods, and the upper positioning ring and the lower positioning ring are placed in the corresponding transformer casting bucket, and then according to the length of the holes corresponding to the various long holes in the upper positioning ring, each columnar stay is inserted into the corresponding long hole in turn to form a corresponding stay assembly, and then casting can be carried out.

[0009] 1. Compared with the existing method of evenly arranging through holes for inserting columnar stays on the corresponding positioning ring, this scheme is to connect multiple through holes to form a new long strip hole, so that the number of columnar stays that can be inserted into a single hole is greater, and the single columnar stays are connected into pieces, that is, the volume occupied by the columnar stays is larger. In this way, after the subsequent pouring is completed, after the columnar stays are removed, the ventilation channel left is larger, and the corresponding heat dissipation effect of the transformer is better.

[0010] 2. At the same time, the support bar assembly of this solution is composed of multiple columnar supports, so that the number of columnar supports can be set according to actual needs, thereby realizing flexible setting of the support bar assembly, greatly improving the versatility of the support bar assembly, improving scene adaptability, and reducing costs.

[0011] Furthermore, the cross section of the columnar strut is one of a circle, a square, a rectangle, a trapezoid, and other polygons.

[0012] Beneficial effects: In this solution, the cross-section of the columnar struts can be selected from a variety of polygonal or circular shapes, which greatly improves the diversity of the struts.

[0013] Furthermore, the columnar stays are arranged separately.

[0014] Beneficial effects: In this solution, the columnar struts are individually arranged so that the corresponding strut assembly is assembled by a plurality of columnar struts, so that when facing long strip holes of different lengths, they can be freely arranged, which greatly improves the diversification and diversification of the use of the corresponding columnar struts. At the same time, the individually arranged columnar struts can also save labor while meeting the needs of the long strip holes.

[0015] Furthermore, the columnar struts are hingedly connected to each other.

[0016] Beneficial effect: In the present solution, the columnar struts are hingedly arranged, so that the strut assembly formed by the columnar struts can adapt to the elongated holes with different curved paths, that is, it is easier to install in the elongated holes with different curved paths and sizes, thereby improving the flexibility of installation.

[0017] Although the columnar braces are hinged, they can still maintain sufficient rigidity under normal use to ensure the overall stability of the structure.

[0018] Furthermore, a hinge column is arranged on the left side wall of the columnar support bar, and a hinge groove is opened on the right side wall of the columnar support bar; the hinge column and the hinge groove form a hinge setting between different columnar support bars.

[0019] Beneficial effect: In the present solution, the hinged connection between the columnar struts is formed by inserting a hinge column on one of the columnar struts into a hinge groove on another columnar strut. The design of the hinge column and the hinge groove allows the struts to rotate relative to each other, thereby better adapting to the long strip holes with different curved paths.

[0020] The hinged design allows the stay to be quickly inserted into the elongated hole of the locating ring, simplifying the installation process.

[0021] The hinged structure can disperse the stress generated by the stays during installation and use, reducing the risk of damage to a single component due to excessive stress.

[0022] The present invention also discloses a transformer support bar installation method, using the above-mentioned transformer support bar structure, comprising the following steps:

[0023] S1. Open a number of long strip holes at the same position of the upper positioning ring and the lower positioning ring;

[0024] S2. Fix the distance between the upper positioning ring and the lower positioning ring by means of a support rod, and align each of the long strip holes on the upper positioning ring with each of the long strip holes on the lower positioning ring one by one;

[0025] S3. According to each of the elongated holes on the upper positioning ring, a plurality of columnar stays are sequentially inserted to form a stay assembly consisting of a plurality of columnar stays corresponding to each of the elongated holes in the elongated holes.

[0029] The following is further described in detail through specific implementation methods:

[0030] The markings in the drawings of the specification include: an upper positioning ring 1, a lower positioning ring 2, a long strip hole 3, a columnar support bar 4, a hinge column 5, and a hinge groove 6.

[0031] Embodiment 1

[0032] A transformer brace structure, basically as Figure 1As shown, it includes an upper positioning ring 1, a lower positioning ring 2, and a support bar assembly arranged between the upper positioning ring 1 and the lower positioning ring 2; the support bar assembly includes a plurality of columnar support bars 4; in this embodiment, the cross section of the columnar support bar 4 is one of a circle, a square, a rectangle, a trapezoid, and other polygons. In this embodiment, the cross section of the columnar support bar 4 is a rectangle.

[0033] The upper positioning ring 1 and the lower positioning ring 2 are both provided with a plurality of long strip holes 3 for inserting the support bar components.

[0034] The lengths of the elongated holes 3 are different. In this embodiment, there are 8 elongated holes 3. Although the lengths of the elongated holes 3 are different, the number of columnar stays 4 that can be inserted into each elongated hole 3 is a positive integer. In other embodiments, the lengths of the elongated holes 3 can also be set to be the same, and the specific number and length can be set according to actual conditions.

[0035] The columnar stays 4 are arranged separately. In this embodiment, the columnar stays 4 are not connected, and only closely contact each other when inserted into the long strip hole 3.

[0036] like Figure 2 As shown, this embodiment also discloses a transformer support bar installation method, using the above-mentioned transformer support bar structure, comprising the following steps:

[0037] S1, opening a plurality of long strip holes 3 at the same position of the upper positioning ring 1 and the lower positioning ring 2;

[0038] S2. Fix the distance between the upper positioning ring 1 and the lower positioning ring 2 by using a support rod, and align each of the elongated holes 3 on the upper positioning ring 1 with each of the elongated holes 3 on the lower positioning ring 2 one by one; in this embodiment, both the upper positioning ring 1 and the lower positioning ring 2 are provided with mounting holes for the support rod to extend into, and the support rod is provided with a threaded portion, and the upper and lower positioning rings 2 are fixed by setting a nut.

[0039] S3. According to each of the long strip holes 3 on the upper positioning ring 1, a number of columnar struts 4 are inserted in sequence, and a strut assembly consisting of a plurality of columnar struts 4 corresponding to each of the long strip holes 3 is formed in the long strip holes 3. In this embodiment, after fixing the distance between the upper positioning ring 1 and the lower positioning ring 2 by the support rod, the entire structure is placed in the transformer casting bucket, and then the columnar struts 4 can be inserted into the corresponding long strip holes 3 in sequence, and different numbers of columnar struts 4 can be inserted according to the long strip holes 3 of different lengths, so as to form a strut assembly corresponding to each rectangular hole, and then casting can be carried out. In this embodiment, in order to facilitate the demoulding of each columnar strut 4 in the strut assembly after casting is completed, a polyester film with a release agent is set on the inner and outer surfaces of the strut assembly before it is placed in the transformer casting bucket.

[0040] Embodiment 2

[0041] like Figure 3 As shown, compared with the first embodiment, the difference of this embodiment is that the columnar struts 4 are hinged. A hinge column 5 is provided on the left wall of the columnar strut 4, and a hinge groove 6 is provided on the right wall of the columnar strut 4; the hinge column 5 and the hinge groove 6 form a hinged setting between different columnar struts 4.

[0042] In this embodiment, compared with the columnar struts 4 in the first embodiment which are individually arranged, the columnar struts 4 in this embodiment are hingedly arranged, so that when the elongated holes 3 are arranged on the upper and lower positioning rings 2, they can be arranged to have a certain curved path. In specific use, the hinge column 5 on one of the columnar struts 4 is inserted into the hinge groove 6 of another columnar strut 4, and then a corresponding hinged connection is formed. At this time, since the columnar struts 4 can be rotated at a preset angle, after multiple columnar struts 4 are hinged, the entire strut assembly can adapt to the elongated holes 3 with different curved paths.

[0043] In this embodiment, in order to facilitate the removal of the brace assembly after casting, a support plate is provided at the bottom of the hinge groove 6, and a notch corresponding to the height of the support plate is provided at the bottom of the hinge column 5. When the hinge column 5 is fully inserted into the hinge groove 6, the support plate matches with the notch. When it is necessary to remove the brace assembly, it is only necessary to lift up a columnar brace 4. At this time, the support plate of the hinge groove 6 corresponding to the columnar brace 4 will also lift up the columnar brace 4 matched with its hinge groove 6, thereby lifting up other columnar braces 4 following the columnar brace 4 together, and then realizing the synchronous removal of multiple columnar braces 4, which greatly facilitates the demoulding of the brace assembly after casting.
