Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology, specifically to a shock-absorbing dry-type transformer with a double-foot structure. Background Technology

[0002] With increasing awareness of environmental protection and safety, countries and international organizations have introduced increasingly stringent standards for limiting transformer vibration and noise. As urbanization and industrialization progress and application scenarios expand, even higher demands are being placed on vibration reduction technology.

[0003] In existing technology, during transformer operation, the transformer generates magnetostrictive vibration of the core, electromagnetic force vibration of the windings, and auxiliary vibration of the cooling system. These vibrations are directly transmitted to the foundation (ground, floor, steel structure) through the base, resulting in excessive vibration and noise, which does not meet the limits set by international organizations.

[0004] Therefore, how to improve the reliability of existing transformer base structures to achieve the effect of "vibration reduction + noise reduction" is a problem that needs to be solved in this field. Utility Model Content

[0005] To address the technical problem of low reliability in existing transformer base structures, the purpose of this utility model is to provide a vibration-damping dry-type transformer double-base structure. This structure can prevent vibration from being directly transmitted to the foundation and building structure, ultimately achieving the effect of "vibration reduction + noise reduction", effectively overcoming the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a shock-absorbing dry-type transformer double-foot structure, which includes a foot structure, a support plate structure, a shock-absorbing structure, and a fastening structure. The foot structure includes an upper foot assembly and a lower foot assembly, and the shock-absorbing structure is disposed between the upper foot assembly and the lower foot assembly and connected by the fastening structure.

[0007] Furthermore, the upper base assembly is composed of a first steel plate, a first side steel plate, and a second side steel plate. The first side steel plate and the second side steel plate are disposed on both sides of the first steel plate and integrally form a first channel steel with the first steel plate.

[0008] Furthermore, the lower base assembly is composed of a second steel plate, a third side steel plate, and a fourth side steel plate. The third side steel plate and the fourth side steel plate are disposed on both sides of the second steel plate and integrally form a second channel steel with the second steel plate.

[0009] Furthermore, the length of the upper foot assembly is less than that of the lower foot assembly, and the width of the upper foot assembly is greater than that of the lower foot assembly.

[0010] Furthermore, the shock-absorbing structure includes several shock-absorbing pads, wherein two shock-absorbing pads are respectively installed at the connection between the upper base assembly and the lower base assembly, and the several shock-absorbing pads are distributed in the middle of the upper base assembly and the lower base assembly.

[0011] Furthermore, the shock-absorbing pad has grooves at equal intervals on one side.

[0012] Furthermore, a support plate structure is provided between the fastening structure and the lower foot assembly.

[0013] The vibration-damping dry-type transformer double-foot structure provided by this utility model can dissipate the vibration energy of the transformer during operation through the elastic deformation energy or a small amount of heat energy of the double-foot vibration-damping element by setting vibration-damping elements at the foot structure, thereby avoiding the vibration from being directly transmitted to the foundation and building structure, and ultimately achieving the effect of "vibration reduction + noise reduction".

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0017] The existing transformer base structure has the technical problem of low reliability. In order to address this technical problem, this utility model provides a vibration-damping dry-type transformer double base structure. By setting vibration damping elements at the base structure, the vibration energy of the transformer during operation can be consumed by the elastic deformation energy or a small amount of heat energy of the double base vibration damping elements, avoiding the vibration from being directly transmitted to the foundation and building structure, and finally achieving the effect of "vibration reduction + noise reduction".

[0018] See Figures 1-2 The shock-absorbing dry-type transformer double-foot structure provided by this utility model includes a foot structure 1, a shock-absorbing structure 2, and a fastening structure 3.

[0019] The base structure 1 includes an upper base assembly 11 and a lower base assembly 12. The upper base assembly 11 and the lower base assembly 12 work together to form a double base structure, which can further improve the vibration reduction and noise reduction effect.

[0020] Furthermore, the upper base assembly 11 is composed of a first steel plate, a first side steel plate, and a second side steel plate. The first side steel plate and the second side steel plate are disposed on both sides of the first steel plate and integrally form a first channel steel with the first steel plate.

[0021] The first steel plate has multiple sets of connecting holes evenly spaced on its end face. For example, see [link to example]. Figure 3 In this scheme, the end face of the first steel plate is provided with a first set of connecting holes 111 and a second set of connecting holes 112. The first set of connecting holes 111 is symmetrically arranged at both ends of the end face of the first steel plate, and the second set of connecting holes 112 is symmetrically arranged between the first set of connecting holes 111. The first set of connecting holes 111 is used as connecting and fixing holes for the upper and lower base components, and the second set of connecting holes 112 is used as connecting and fixing holes for the transformer.

[0022] It should be noted that this solution does not limit the design of the connection holes; the specific number, function, and arrangement can be determined according to the actual situation.

[0023] The lower base assembly 12 is composed of a second steel plate, a third side steel plate, and a fourth side steel plate. The third side steel plate and the fourth side steel plate are located on both sides of the second steel plate and are integrally formed with the second steel plate to form a second channel steel.

[0024] The second steel plate has multiple sets of connecting holes at equal intervals on its end face. For example, see [link to example]. Figure 3 In this scheme, the end face of the second steel plate is provided with a third set of connecting holes 121 and a fourth set of connecting holes 122.

[0025] The arrangement of the third set of connecting holes 121 and the fourth set of connecting holes 122 here corresponds to the arrangement of the first set of connecting holes 111 and the second set of connecting holes 112 in the upper foot assembly, which enables the fastening structure 3 to pass through and connect the upper foot assembly 11 and the lower foot assembly 12.

[0026] The upper base assembly 11 and the lower base assembly 12 form a first channel steel and a second channel steel. The length of the first channel steel is less than that of the second channel steel, and the width of the first channel steel is greater than that of the second channel steel. This scheme does not limit the specific width and length of the first and second channel steels, but can be determined according to the capacity of the transformer.

[0027] The shock-absorbing structure 2 includes several anti-vibration pads. In this scheme, three anti-vibration pads are used. The three anti-vibration pads are placed in the middle of the upper and lower base components. Two of the anti-vibration pads are installed at the connection and fixing holes of the upper and lower base components respectively. The first set of connection holes 111 and the third set of connection holes 121 of the upper and lower base components are provided with the same fifth connection hole for fastening the connection of the structure 3. The other anti-vibration pad is set in the middle of the upper and lower base components.

[0028] The shock-absorbing pad is preferably made of rubber, see [reference]. Figure 4 The rubber synchronous belt preferably has equidistant slots 21 on one side. With one end of the slot 21 placed opposite the lower base assembly 12, the slotted rubber synchronous belt increases friction, further absorbing vibration energy during equipment operation and reducing operating noise. Therefore, by distributing several anti-vibration pads between the upper and lower base components, the vibration energy of the transformer during operation can be dissipated through the elastic deformation energy or a small amount of heat energy of the double base damping element, avoiding the vibration from being directly transmitted to the foundation and building structure, and ultimately achieving the effect of "vibration reduction + noise reduction".

[0029] This plan does not limit the number of shock-absorbing pads; the specific number can be determined based on the actual situation.

[0030] The structure of fastening structure 3 is not limited in this scheme. As an example, it includes bolts, nuts, washers, and spring washers of appropriate diameter and length. The first set of connecting holes 111 of the upper foot assembly 11, the fifth connecting hole of the shock-absorbing pad 2, and the third set of connecting holes 121 of the lower foot assembly 12 are aligned and fixed.

[0031] Similarly, the double-foot structure can be directly connected to the transformer by the center of the second set of connecting holes 112 and the fourth set of connecting holes 121 on the upper and lower foot assemblies corresponding to the fastening structure 3.

[0032] The structure of fastening structure 3 is well known to those skilled in the art, and will not be described in detail here.

[0033] Secondly, a support plate structure 4 is provided between the fastening structure 3 and the lower foot assembly 112. The support plate structure 4 is a flat steel plate. By setting up a steel support system, the support plate is connected to the main structure with bolts to form a stable frame, ensuring the stability of the structure.

[0034] The vibration-damping dry-type transformer with double-foot structure constructed by the above scheme can reduce the vibration and noise generated during transformer operation and block and weaken the transmission path of vibration energy by changing the structure of the transformer feet.

[0035] Meanwhile, this utility model has a low cost, high reliability, requires no maintenance, and is easy to install, making it suitable for any conventional site.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
