Description

[0002] In power systems, transformers play a crucial role as core equipment, and their normal operation is essential for a stable power supply. The transformer tank casing, as a key component protecting internal elements, is exposed to a complex and ever-changing environment for extended periods, facing numerous severe challenges. During actual operation, the tank casing is subjected to multiple impact risks, including mechanical collisions, vibrations, and extreme weather conditions. Traditional transformer tank casings typically employ a corrugated plate structure to enhance heat dissipation and mechanical strength.

[0003] Existing corrugated structures are primarily designed to address the thermal expansion and contraction during transformer operation, exhibiting significant shortcomings in impact resistance. When external forces act directly on the corrugated plate, its limited ability to disperse impact forces means that the force cannot be effectively dispersed and absorbed, easily leading to significant localized stress concentration and consequently, localized deformation. Therefore, an impact-resistant transformer tank shell is proposed. Utility Model Content

Therefore, the above terms should not be construed as limitations on this utility model.

[0037] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0038] Please see Figure 1-6 An impact-resistant transformer tank shell includes: a tank shell body 1; a corrugated plate structure 2, which is arranged around the periphery of the tank shell body 1 and protrudes outward; an impact-resistant member 3, which is integrally formed along the contour edge of the corrugated plate structure 2, including a force-bearing frame 31 and an inner contact frame 32 connected to each other, the inner contact frame 32 abutting against the outer contour of the corrugated plate structure 2; and a connecting member 4, which is disposed between the tank shell body 1 and the impact-resistant member 3, for providing support and position adjustment functions.

[0039] The shock-resistant transformer tank shell of this application mainly includes the tank shell body 1, corrugated plate structure 2, shock-resistant components 3, and connecting components 4.

[0040] The corrugated plate structure 2 is arranged around the periphery of the main body 1 of the fuel tank shell and protrudes outward. In practical applications, the corrugated plate structure 2 is generally fixed to the main body 1 of the fuel tank shell by welding to form the overall structure of the shell, thereby enhancing the heat dissipation and mechanical strength of the fuel tank shell.

[0041] The impact-resistant component 3 is integrally formed along the contour edge of the corrugated plate structure 2. It includes a load-bearing frame 31 and an inner contact frame 32 that are connected to each other. The inner contact frame 32 abuts against the outer contour of the corrugated plate structure 2. The load-bearing frame 31 of the impact-resistant component 3 has an exposed impact contact surface, and the inner contact frame 32 has a matching contact surface that matches the outer contour of the corrugated plate structure 2. The cross-section of the load-bearing frame 31 is arc-shaped, and its outer surface forms an impact contact surface. The area of ​​the matching contact surface of the inner contact frame 32 is larger than the area of ​​the impact contact surface of the load-bearing frame 31. This design is beneficial for better adapting to external impact forces and dispersing the force by increasing the contact area.

[0042] In a specific implementation, two sets of impact-resistant components 3 may be provided along the upper and lower edges of the corrugated plate structure 2 to further adapt to external impact forces.

[0043] The contact surface of the inner contact frame 32 is a planar structure, and a buffer inner layer 5 is provided on the planar surface. The buffer inner layer 5 is movably connected to the force-bearing frame 31 through an elastic connection structure. Specifically, the force-bearing frame 31 has an inner groove 311 on the side facing the buffer inner layer 5. The buffer inner layer 5 and the inner wall of the inner groove 311 are connected by several spring elements 51 to achieve the effect of buffering and shock absorption. When subjected to external impact, the spring elements 51 can deform and absorb part of the impact energy, thereby reducing the impact on the main body 1 of the fuel tank shell.

[0044] Connector 4 is disposed between the fuel tank outer shell body 1 and the impact-resistant member 3 to provide support and position adjustment. Connector 4 includes a right-angle connecting plate 41, an upper support plate 42, and a lower support plate 43. The right-angle connecting plate 41 has two mutually perpendicular mounting planes. The first mounting plane fits against the corner of the fuel tank outer shell body 1, and the second mounting plane is fixed to the side wall of the fuel tank outer shell body 1 by fasteners 44, wherein the fasteners 44 can be bolts. The right-angle connecting plate 41 can be fixed at any suitable height on the fuel tank outer shell body 1 by bolts, thereby adjusting the position of the impact-resistant member 3 relative to the corrugated plate structure 2. The upper support plate 42 is detachably mounted on the top of the right-angle connecting plate 41. The lower support plate 43 is integrally formed with the bottom of the right-angle connecting plate 41 and extends outward. The upper support plate 42 and the lower support plate 43 together form a clamping and fixing structure for the load-bearing frame 31. The upper support plate 42 is provided with a sleeve hole 421, and the top of the right-angle connecting plate 41 is provided with a sleeve rod 422 that is interference-fitted with the sleeve hole 421, facilitating the disassembly and assembly of the upper support plate 42. At least two sets of connecting parts 4 are evenly distributed around the circumference of the main body 1 of the tank shell to ensure stable support for the impact-resistant parts 3. The extended end plane of the lower support plate 43 is coplanar with the load-bearing frame 31, making the load-bearing frame 31 the main contact surface of the impact force, and its protruding range is also the range of movement of the impact force.

[0045] Working principle

[0046] When the transformer tank casing is subjected to an external impact, the impact force first acts on the arc-shaped impact contact surface of the stress-bearing frame 31 of the impact-resistant component 3. Since the cross-section of the stress-bearing frame 31 is arc-shaped, it can play a certain role in dispersing and guiding the impact force, so that the impact force is dispersed and transmitted along the arc-shaped surface, avoiding excessive local stress concentration.

[0047] As the impact force is transmitted, the impact energy is transferred to the inner buffer layer 5 connected to the load-bearing frame 31. At this time, the inner buffer layer 5 is connected to the inner wall of the inner groove 311 of the load-bearing frame 31 through the spring element 51 in the elastic connection structure. The spring element 51 will be compressed or deformed under the action of the impact force, thereby absorbing and consuming part of the impact energy, playing a role in buffering and shock absorption, and further reducing the impact of the impact force on the main body of the fuel tank shell 1.

[0048] Meanwhile, the inner contact frame 32 of the impact-resistant component 3 abuts against the outer contour of the corrugated plate structure 2, and the inner contact frame 32 has a large matching contact surface area, which can evenly transmit the dispersed impact force to the corrugated plate structure 2 when it is impacted, so as to avoid the corrugated plate structure 2 from being deformed or damaged due to excessive local stress, thereby effectively protecting the integrity of the main body 1 of the fuel tank shell and preventing leakage and other problems.

[0049] The right-angle connecting plate 41, the upper support plate 42 and the lower support plate 43 in the connector 4 cooperate with each other to firmly connect the impact-resistant component 3 to the main body of the fuel tank shell 1. The position of the right-angle connecting plate 41 on the side wall of the main body of the fuel tank shell 1 can be adjusted to meet the impact resistance requirements under different conditions, ensuring that the impact-resistant component 3 can play the best impact resistance role in the appropriate position.

[0050] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
