Description

Technical Field

[0001] The utility model relates to the field of transformer assembly, in particular to a transformer heavy-load foundation conversion bracket. Background Art

[0002] A transformer is an electrical device widely used in power systems to change the magnitude of AC voltage. Its basic principle is based on electromagnetic induction, transferring electrical energy through magnetic field coupling between a primary coil and a secondary coil. When AC current passes through the primary coil, it generates an alternating magnetic field in the iron core. This field induces an electromotive force in the secondary coil, thereby achieving voltage conversion. The use of transformers can effectively improve the efficiency and reliability of power systems, meet the needs of diverse loads, and increase power utilization.

[0003] With the advancement of low-carbon strategic planning, the number of projects to improve the efficiency of old transformers is increasing. These projects involve numerous transformer manufacturers, each with its own distinct transformer design styles, resulting in significant variations in foundation adjustment dimensions and spacing. Furthermore, due to the high cost of transformer foundations, and the fact that their designed service life and foundation weight capacity still meet the requirements for increased transformer capacity, recasting the foundation to replace the transformer would result in significant waste of resources and economic losses.

[0004] The heavy-duty transformer foundation conversion bracket is a device specifically designed for transformer foundation replacement and upgrading. The heavy-duty foundation conversion bracket enables the rapid replacement and installation of transformers without re-casting the foundation. This requires a conversion device that can quickly connect the existing foundation and the replacement transformer. Utility Model Content

[0005] The purpose of the utility model is to provide a transformer heavy-duty foundation conversion bracket to address the problem that the prior art has low assembly efficiency due to the need to assemble each phase separately, making it difficult to meet the needs of fast and efficient assembly of modern transformers.

[0006] The utility model is realized through the following technical solutions: a transformer heavy-load foundation conversion bracket, comprising an upper support plate and a lower support plate; a crossbeam is arranged between the upper support plate and the lower support plate; and further comprising a connecting hole, wherein the connecting hole is arranged at the upper part of the crossbeam, and the connecting hole is a long slot hole.

[0007] Preferably, four connecting holes are provided.

[0008] Preferably, a reinforcing plate is further included, and the reinforcing plate is arranged between the upper support plate and the lower support plate.

[0009] Preferably, the reinforcing plate is perpendicular to the upper support plate and the lower support plate.

[0010] Preferably, the cross beam is welded to the upper support plate and the lower support plate.

[0011] Preferably, the cross beam is perpendicular to the upper support plate and the lower support plate.

[0012] Preferably, the height of the right-angle welds between the crossbeam and the upper support plate and the lower support plate is 10 mm.

[0013] Preferably, the upper support plate is a 40mm steel plate.

[0014] Compared with existing technologies, this new heavy-duty conversion bracket offers the following advantages: Three of these brackets can support a maximum load of 220 tons, meeting the replacement needs of all State Grid three-winding transformers with a capacity of 240 MVA or less. The welded connection of the upper and lower support plates and crossbeams ensures the bracket's overall structural stability and strength, enabling it to withstand heavy loads. The diameter and positioning dimensions of the connection holes can be adjusted on-site to accommodate different transformer foundation dimensions, making the bracket highly adaptable and facilitating transformer replacement.

[0018] The present invention will be further described with reference to specific embodiments, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0019] As shown in the reference figures, the present invention discloses a heavy-duty transformer foundation conversion bracket, comprising an upper support plate 1 and a lower support plate 2; a crossbeam 3 disposed between the upper and lower support plates 1 and 2; and connection holes 4 disposed above the crossbeam 3. Four connection holes 4 are evenly distributed on the crossbeam 3 for ease of installation and transportation. For on-site installation of the heavy-duty foundation mounting bracket, all four connection holes 4 are required; using only two or three of the connection holes 4 is not permitted. The connection holes 4 are elongated slots. The upper and lower support plates 1, 2, and crossbeam 3 must be leveled before welding. Welding must be performed on a dedicated horizontal workbench to prevent deformation of the upper and lower support plates 1, 2, and flatness after welding. During use, the diameter and positioning dimensions of the connection holes 4 can be adjusted on-site to accommodate any transformer foundation size. When replacing a transformer on-site, the local foundation conversion bracket can simply be placed horizontally on the existing foundation strips, with the transformer resting on the bracket. The transformer base can be moved at any point on the foundation conversion bracket.

[0020] It also includes a reinforcing plate 5, which is arranged between the upper support plate 1 and the lower support plate 2; the reinforcing plate 5 is perpendicular to the upper support plate 1 and the lower support plate 2; and the crossbeam 3 is perpendicular to the upper support plate 1 and the lower support plate 2.

[0021] The crossbeam 3 is welded to the upper support plate 1 and the lower support plate 2; when welding, the upper support plate 1, the lower support plate 2, and the crossbeam 3 are first spot welded together and then full welded. When welding, the crossbeam 3 and the upper support plate 1 and the lower support plate 2 need to ensure that the right-angle weld height is 10 mm, and finally the reinforcement plate is welded.

[0022] The upper support plate 1 is cut as a whole from a 40 mm thick steel plate, and no splicing is allowed in the middle during use; thereby ensuring the overall strength and durability of the bracket.

[0023] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
