Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and more specifically, to a wooden clamp structure and a transformer. Background Technology

[0002] In related technologies, because transformer clamps are generally made of carbon steel as the main material, eddy current losses are easily generated in the alternating magnetic field during transformer operation, causing the transformer temperature to rise. Furthermore, existing transformer clamps cannot ensure sufficient contact between the transformer core and coils and the transformer oil, resulting in inadequate heat dissipation from the core and coils, further increasing the transformer temperature and affecting its normal operation. Utility Model Content

[0003] The main purpose of this utility model is to provide a wooden clamping structure and a transformer to solve the problems of high loss and poor heat dissipation in existing transformers.

[0004] To achieve the above objectives, according to one aspect of the present invention, a wooden clamping structure is provided, comprising:

[0008] Furthermore, the wooden frame includes a square frame, and the uprights include a first upright, a second upright, a third upright, and a fourth upright;

[0009] The first column, the second column, the third column, and the fourth column are arranged sequentially at intervals along the outer perimeter of the square frame and are respectively located at the four apex corners of the square frame.

[0010] Furthermore, the crossbeam assembly includes a first crossbeam, a second crossbeam, a third crossbeam, a fourth crossbeam, a fifth crossbeam, a sixth crossbeam, a seventh crossbeam, and an eighth crossbeam;

[0011] The first crossbeam, the second crossbeam, the third crossbeam, and the fourth crossbeam are all connected between the first column and the second column, and the first crossbeam, the second crossbeam, the third crossbeam, and the fourth crossbeam are arranged at intervals along the height direction of the wooden frame.

[0012] The fifth, sixth, seventh, and eighth crossbeams are all connected between the third and fourth columns, and are arranged at intervals along the height of the wooden frame.

[0013] Furthermore, the first, second, third, and fourth crossbeams are all perpendicular to the first and second columns, and the fifth, sixth, seventh, and eighth crossbeams are all perpendicular to the third and fourth columns.

[0014] Furthermore, the support assembly includes multiple support beams, which are spaced apart along the first direction of the wooden frame and supported at the bottom of the predetermined coil. Each support beam is connected between the second crossbeam and the sixth crossbeam. The top surface of each support beam is provided with the first guide groove, which extends along the length direction of the support beam.

[0015] Furthermore, the beam assembly also includes a ninth beam and a tenth beam, and the wooden frame also includes a first pressing member and a second pressing member;

[0016] The ninth crossbeam is connected between the second column and the third column and is perpendicular to the second column and the third column; the tenth crossbeam is connected between the first column and the fourth column and is perpendicular to the first column and the fourth column; and both the ninth crossbeam and the tenth crossbeam are close to the top of the wooden frame.

[0017] The first pressing member and the second pressing member are connected between the ninth crossbeam and the tenth crossbeam and can be raised and lowered along the height direction of the wooden frame. The first pressing member and the second pressing member are spaced apart along the second direction of the wooden frame.

[0018] Furthermore, the clamping assembly includes multiple clamping beams, which are spaced apart along a first direction of the wooden frame. Each clamping beam is connected between the first clamping member and the second clamping member. The bottom surface of each clamping beam is provided with a second guide groove, which extends along the length direction of the clamping beam.

[0019] Furthermore, the wooden frame also includes a suspension component, and the predetermined iron core includes a ring structure;

[0020] The annular structure is vertically arranged, and the suspension member is vertically connected between the fourth crossbeam and the eighth crossbeam and passes through the annular structure.

[0021] Furthermore, the suspension member is provided with a limiting port, which extends along the length direction of the suspension member, and the suspension member is engaged with the inner wall surface of the predetermined iron core through the limiting port.

[0022] Furthermore, the wooden frame also includes multiple reinforcing members, which are disposed between the first and second crossbeams, between the second and third crossbeams, between the third and fourth crossbeams, between the fifth and sixth crossbeams, between the sixth and seventh crossbeams, and between the seventh and eighth crossbeams; and / or,

Furthermore, a first guide groove and a second guide groove are respectively provided at the bottom and top of the receiving cavity, which can improve the heat dissipation effect of the wooden frame. In actual operation, when the wooden clamping structure is applied to an oil-immersed transformer, transformer oil can flow through the first and second guide grooves, thus increasing the contact area between the transformer oil and the predetermined iron core and predetermined coil. This allows the transformer oil to better carry away the heat generated by the predetermined iron core and predetermined coil during operation, thereby improving the heat dissipation effect of the wooden clamping structure. When the wooden clamping structure is applied to a dry-type transformer, airflow can flow through the first and second guide grooves, thus increasing the contact area between the predetermined iron core and predetermined coil and the airflow, thereby improving the heat dissipation effect of the wooden clamping structure. Furthermore, the wooden clamping structure of this application can also prevent the magnetic field of the predetermined coil from generating eddy currents on the wooden clamping structure, which can avoid both power loss caused by eddy currents and transformer temperature rise caused by eddy currents.

[0026] In other words, compared with existing transformer clamps, this application, by adopting a wooden clamp structure and setting a first guide groove and a second guide groove in the accommodating cavity, can not only reduce transformer losses but also improve the transformer's heat dissipation effect.

[0027] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0036] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0039] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0040] As mentioned in the background section, in related technologies, transformer clamps are generally made primarily of carbon steel, which easily leads to eddy current losses in the alternating magnetic field during transformer operation, causing the transformer temperature to rise. Furthermore, existing transformer clamps cannot ensure sufficient contact between the transformer core and coils and the transformer oil, resulting in inadequate heat dissipation and further temperature increases, affecting the normal operation of the transformer. Therefore, this application provides a wooden clamp structure and transformer, which can not only reduce transformer losses but also improve heat dissipation.

[0041] See Figures 1 to 5 As shown, this application provides a wooden clamping structure 100, which includes a wooden frame 10.

[0042] The wooden frame 10 has a cavity 11 for installing a predetermined iron core 200 and a predetermined coil 300. The bottom of the cavity 11 has a first guide groove 1411 and the top of the cavity 11 has a second guide groove 1511.

[0043] In this application, the wooden frame 10 is provided with a receiving cavity 11 for mounting the predetermined iron core 200 and the predetermined coil 300, so that the predetermined iron core 200 and the predetermined coil 300 can be placed tightly and securely in the wooden frame 10. The bottom and top of the receiving cavity 11 are respectively provided with a first guide groove 1411 and a second guide groove 1511, which can improve the heat dissipation effect of the wooden frame 10. In actual operation, when the wooden clamping structure 100 is applied to an oil-immersed transformer (not shown in the figure), transformer oil can flow through the first guide groove 1411 and the second guide groove 1511. This increases the contact area between the transformer oil and the predetermined iron core 200 and the predetermined coil 300, allowing the transformer oil to better remove the heat generated by the predetermined iron core 200 and the predetermined coil 300 during operation, thereby improving the heat dissipation effect of the wooden clamping structure 100. When the wooden clamp structure 100 is applied to a dry-type transformer (not shown in the figure), airflow is allowed to pass through the first guide groove 1411 and the second guide groove 1511. This increases the contact area between the predetermined iron core 200 and the predetermined coil 300 and the airflow, thereby improving the heat dissipation effect of the wooden clamp structure 100. Furthermore, the wooden clamp structure 100 of this application can also prevent the magnetic field of the predetermined coil 300 from generating eddy currents on the wooden clamp structure 100, thus avoiding both power loss and transformer temperature rise caused by eddy currents.

[0044] In other words, compared with existing transformer clamps, this application adopts a wooden clamp structure 100 and sets a first guide groove 1411 and a second guide groove 1511 in the accommodating cavity 11, which can not only reduce transformer losses, but also improve the heat dissipation effect of the transformer.

[0045] It is understandable that the oil-immersed transformer mentioned above is a type of transformer that requires transformer oil to be poured into the transformer to dissipate heat from the internal components, while the dry-type transformer mentioned above is a type of transformer that does not require transformer oil to dissipate heat from the internal components, but instead uses natural air cooling or forced air cooling to dissipate heat from the internal components.

[0046] Further, see Figures 1 to 4As shown, the wooden frame 10 includes uprights 12, crossbeam assemblies 13, support assemblies 14, and clamping assemblies 15. There are multiple uprights 12, which are spaced apart along the outer perimeter of the wooden frame 10. At least two adjacent uprights 12 are connected by crossbeam assemblies 13 to form a cavity 11. The support assemblies 14 and clamping assemblies 15 are both located in the cavity 11 and are spaced apart along the height direction of the wooden frame 10. A first flow channel 1411 is provided on the top surface of the support assembly 14, and a second flow channel 1511 is provided on the bottom surface of the clamping assembly 15.

[0047] Specifically, the height direction of the wooden frame 10 is... Figure 1 and Figure 3The height direction is shown in the figure. Multiple uprights 12 are spaced apart along the outer perimeter of the wooden frame 10, providing basic support for the entire wooden clamping structure 100. The uprights 12 are evenly distributed around the perimeter, effectively bearing external forces from all directions and ensuring the stability of the wooden frame 10 during installation and use. At least two adjacent uprights 12 are connected by a crossbeam assembly 13 to form a receiving cavity 11. The crossbeam assembly 13 connects the uprights 12 into an integral frame, greatly enhancing the rigidity of the wooden frame 10. This not only further stabilizes the relative positions between the uprights 12 but also disperses external forces, enabling the entire wooden frame 10 to better resist external impacts and improving the reliability of the wooden clamping structure. The support assembly 14 and the clamping assembly 15 are both located in the receiving cavity 11 and spaced apart along the height direction of the wooden frame 10. This layout achieves effective fixation and support for the predetermined iron core 200 and the predetermined coil 300. The support assembly 14 provides support to the predetermined iron core 200 and predetermined coil 300 from below, ensuring their stability under gravity. The clamping assembly 15 applies pressure from above to prevent displacement of the predetermined iron core 200 and predetermined coil 300 due to vibration or other reasons during operation. The first guide channel 1411 is provided on the top surface of the support assembly 14, and the second guide channel 1511 is provided on the bottom surface of the clamping assembly 15. This increases the contact area between the predetermined iron core 200 and predetermined coil 300 and the transformer oil or air, thereby improving the cooling effect of the wooden frame 10 and achieving the purpose of further cooling the predetermined iron core 200 and predetermined coil 300. The wooden frame 10 consists of columns 12, beam assemblies 13, support assemblies 14, and clamping assemblies 15. The components can be connected by mortise and tenon joints, which not only makes the wooden clamp structure 100 easier to install, but also allows each component to be manufactured and transported separately and assembled on-site, reducing installation difficulty and improving installation efficiency. During maintenance, because each component is relatively independent, if a problem occurs in a component, such as damage to the support component 14 or adjustment of the pressure of the clamping component 15, maintenance personnel can repair, replace, or adjust that component individually without affecting the normal operation of other components. This flexibility shortens maintenance time, reduces maintenance costs, and ensures that the wooden clamping structure 100 can quickly return to normal operation. By adjusting the number of columns 12, the connection method of the beam assembly 13, and the specifications of the support assembly 14 and the clamping assembly 15, different specifications of the wooden clamping structure 100 can be customized according to the different sizes, shapes, and usage requirements of the predetermined iron core 200 and predetermined coil 300, improving the versatility of the wooden clamping structure 100 and enabling it to be applied to a variety of electrical equipment.

[0048] Further, see Figures 1 to 3As shown, the wooden frame 10 includes a square frame 101, and the columns 12 include a first column 121, a second column 122, a third column 123, and a fourth column 124; the first column 121, the second column 122, the third column 123, and the fourth column 124 are arranged sequentially at intervals along the outer periphery of the square frame 101 and are respectively located at the four apex corners of the square frame 101.

[0049] Specifically, the wooden frame 10 adopts a square frame structure 101, with the first column 121, the second column 122, the third column 123, and the fourth column 124 located at the four apex corners of the square frame 101 and spaced apart along the outer perimeter. This layout allows the wooden frame 10 to provide relatively balanced support in all directions, preventing deformation of the wooden frame 10 due to uneven force, ensuring stable placement of internal components, and guaranteeing the normal operation of the equipment equipped with the wooden clamp structure 100 of this application. The square frame 101, together with the four apex columns 12, forms a stable mechanical structure. This stable structure can effectively resist external forces, reduce the risk of damage to the wooden frame 10, and protect the internal predetermined iron core 200 and predetermined coil 300 from damage. The accommodating cavity 11 formed by the four columns 12 presents a relatively regular square space, which is of great significance for the installation and layout of the predetermined iron core 200 and predetermined coil 300. The square accommodating cavity 11 facilitates precise design and arrangement based on the shape and size of the predetermined iron core 200 and predetermined coil 300, ensuring that the predetermined iron core 200 and predetermined coil 300 fit tightly against the inner wall of the accommodating cavity 11 and guaranteeing the stability of the predetermined iron core 200 and predetermined coil 300 after installation. The structure of the square frame 101 and the four uprights 12 is simple and clear, facilitating assembly. When assembling the wooden frame 10, the operator can clearly determine the position of each upright and install the first upright 121, the second upright 122, the third upright 123, and the fourth upright 124 sequentially at the four apex corners of the square frame 101. The operation is relatively simple, reducing assembly difficulty and improving assembly efficiency. At the same time, this simple structure also facilitates quality inspection during the assembly process, ensuring that each upright 12 is installed in place and guaranteeing the overall quality of the wooden frame 10.

[0050] Further, see Figures 1 to 3As shown, the crossbeam assembly 13 includes a first crossbeam 130, a second crossbeam 131, a third crossbeam 132, a fourth crossbeam 133, a fifth crossbeam 134, a sixth crossbeam 135, a seventh crossbeam 136, and an eighth crossbeam 137. The first crossbeam 130, the second crossbeam 131, the third crossbeam 132, and the fourth crossbeam 133 are all connected between the first column 121 and the second column 122, and are arranged at intervals along the height direction of the wooden frame 10. The fifth crossbeam 134, the sixth crossbeam 135, the seventh crossbeam 136, and the eighth crossbeam 137 are all connected between the third column 123 and the fourth column 124, and are arranged at intervals along the height direction of the wooden frame 10.

[0051] Specifically, the crossbeam assembly 13 includes multiple crossbeams, such as the first crossbeam 130, the second crossbeam 131, the third crossbeam 132, and the fourth crossbeam 133 connected between the first column 121 and the second column 122, and the fifth crossbeam 134, the sixth crossbeam 135, the seventh crossbeam 136, and the eighth crossbeam 137 connected between the third column 123 and the fourth column 124, and are arranged sequentially at intervals along the height direction of the wooden frame 10. These crossbeams act like reinforcing links, tightly connecting the opposing columns 12, greatly enhancing the overall strength of the wooden frame 10. When the wooden clamping structure 100 is subjected to external forces, the multiple crossbeams work together to disperse stress, preventing stress concentration in a certain part of the column 12, thereby preventing the wooden frame 10 from deforming or being damaged due to uneven stress, and ensuring the safety and stability of the internal predetermined iron core 200 and predetermined coil 300. The crossbeams spaced apart along the height direction of the wooden frame 10 allow the force to be evenly transmitted at different height levels of the wooden frame 10. When the wooden frame 10 is subjected to pressure or tension from above or below, the crossbeams at each level can evenly distribute the force to the columns, thereby transmitting it to the entire frame structure. This ensures that the entire wooden frame 10 can withstand the corresponding external forces at various height positions, improving the stability and load-bearing capacity of the structure, and enabling it to better adapt to the stress requirements under different working conditions. The crossbeams are spaced along the height direction of the wooden frame 10, providing layered support and positioning for the predetermined iron core 200 and predetermined coil 300 within the accommodating cavity 11. Crossbeams at different heights can cooperate with the support assembly 14 and the clamping assembly 15 to accurately position and support the predetermined iron core 200 and predetermined coil 300 in the height direction. This standardized and modular design of the crossbeam assembly 13 facilitates manufacturing, which not only improves production efficiency but also facilitates subsequent quality control and inspection. When installing the wooden frame 10, because the position and connection method of the crossbeams are clear, operators can install each crossbeam sequentially between the corresponding columns 12, making the operation relatively simple, reducing installation difficulty, and improving installation efficiency. During maintenance, if a crossbeam is damaged, the operator can easily locate and replace it without significantly affecting other components, reducing maintenance time and costs and ensuring the wooden clamping structure can quickly return to normal operation. By adjusting the number, spacing, and connection method of the crossbeams, the wooden clamping structure 100 can be flexibly customized according to the size, weight, and usage requirements of different predetermined iron cores 200 and predetermined coils 300. This flexibility allows the wooden clamping structure 100 to adapt to the needs of various electrical equipment, improving its versatility.

[0052] Further, see Figures 1 to 4As shown, the first crossbeam 130, the second crossbeam 131, the third crossbeam 132 and the fourth crossbeam 133 are all perpendicular to the first column 121 and the second column 122, and the fifth crossbeam 134, the sixth crossbeam 135, the seventh crossbeam 136 and the eighth crossbeam 137 are all perpendicular to the third column 123 and the fourth column 124.

[0053] Specifically, the first crossbeam 130, the second crossbeam 131, the third crossbeam 132, and the fourth crossbeam 133 are perpendicularly connected to the first and second uprights 121 and 122, respectively; the fifth crossbeam 134, the sixth crossbeam 135, the seventh crossbeam 136, and the eighth crossbeam 137 are perpendicularly connected to the third and fourth uprights 123 and 124, respectively. This right-angle connection creates a stable mechanical structure. The perpendicular connection allows for effective force transmission and dispersion between the crossbeams and the uprights 12. When the wooden clamp structure 100 is subjected to external forces, the crossbeams can evenly transmit these forces to the uprights 12, which then distribute them throughout the entire wooden frame 10. Compared to non-perpendicular connections, right-angle connections better resist external forces from various directions, reduce the possibility of structural deformation, and ensure that the wooden frame 10 remains stable under complex stress conditions, providing a reliable support environment for the internal predetermined iron core 200 and predetermined coil 300. The vertically connected beams and columns 12 support each other, greatly enhancing the overall rigidity of the wooden frame 10. This increased rigidity means the wooden frame 10 exhibits greater stability in shape and size when subjected to external forces. Under significant external forces, the structure is less prone to twisting or bending, effectively protecting the predetermined iron core 200 and predetermined coil 300 installed within the accommodating cavity 11. This prevents displacement or damage to the predetermined iron core 200 and predetermined coil 300 due to deformation of the wooden frame 10, ensuring the normal operation of equipment such as transformers. The vertical connection design is relatively simple to manufacture, facilitating production operations. Manufacturers can utilize common woodworking techniques and tools to precisely process and assemble the beams and columns 12. Compared to complex angle connections, the processing precision of vertical connections is easier to control, improving production efficiency and reducing production costs. Simultaneously, this simple structure facilitates quality inspection during production, ensuring that each wooden frame 10 meets design standards. During the installation of the wooden frame 10, the vertical relationship between the beams and columns 12 is clear, allowing operators to more easily perform positioning and connection operations. The vertical connection structure makes the installation process more intuitive, reduces installation difficulty, and improves installation efficiency. During maintenance, if it is necessary to replace or repair the beams or columns, the simple structure of the vertical connection allows operators to more easily disassemble and install the relevant components, reducing maintenance time and costs and ensuring that the wooden clamp structure can be quickly restored to normal operation.

[0054] Further, see Figures 1 to 5As shown, the support assembly 14 includes multiple support beams 141. The multiple support beams 141 are spaced apart along the first direction of the wooden frame 10 and supported at the bottom of the predetermined coil 300. Each support beam 141 is connected between the second crossbeam 131 and the sixth crossbeam 135. The top surface of each support beam 141 is provided with a first guide groove 1411, which extends along the length direction of the support beam 141.

[0055] Specifically, the first direction of the wooden frame 10 is... Figure 1 , Figure 3 , Figure 4 as well as Figure 5 The first direction is shown in the diagram. The support assembly 14 consists of multiple support beams 141 spaced apart along the first direction of the wooden frame 10. These support beams 141 collectively support the bottom of the predetermined coil 300. The multiple support beams 141 can evenly distribute the weight of the predetermined coil 300, preventing damage or deformation of the predetermined coil 300 due to excessive local stress. The number of support beams 141 can be reasonably adjusted according to needs and actual conditions. This embodiment shows the case of four support beams 141. The support beams 141 can not only support the predetermined coil 300 and the predetermined iron core 200, but also restrict the degree of freedom of the predetermined coil 300 and the predetermined iron core 200 in the first direction of the wooden frame 10, preventing the predetermined coil 300 and the predetermined iron core 200 from moving under the action of external forces. Each support beam 141 is connected between the second crossbeam 131 and the sixth crossbeam 135. The support beams 141, through their connection with the second crossbeam 131 and the sixth crossbeam 135, form a stable support structure. The second crossbeam 131 and the sixth crossbeam 135 provide lateral constraints for the support beam 141, enhancing the overall stability of the support assembly 14. During transformer operation, it may be affected by external forces such as vibration. This stable structure effectively resists external forces, preventing displacement of the support beam 141 and thus continuously and stably supporting the predetermined coil 300. Each support beam 141 has a first guide groove 1411 extending along its length on its top surface. This allows for better heat dissipation of the predetermined iron core 200 and the predetermined coil 300, thereby improving the heat dissipation effect of the wooden frame 10. Along the length of the support beam 141 (i.e.... Figure 1 and Figure 3The first guide groove 1411, extending in the second direction shown, facilitates the flow of transformer oil or air, which helps dissipate heat from the predetermined coil 300 and the predetermined iron core 200. Multiple support beams 141 are spaced apart along the first direction of the wooden frame 10, providing sufficient support for the predetermined coil 300 while making efficient use of the space within the accommodating cavity 11. The spaced-apart support beams 141 ensure effective support without excessive space occupation, allowing sufficient room for the rational layout of other components (such as the predetermined iron core 200) within the accommodating cavity 11, thus improving the utilization rate of the internal space of the entire wooden clamping structure 100.

[0056] Further, see Figures 1 to 5 As shown, the crossbeam assembly 13 also includes a ninth crossbeam 138 and a tenth crossbeam 139, and the wooden frame 10 also includes a first pressing member 16 and a second pressing member 17; the ninth crossbeam 138 is connected between the second column 122 and the third column 123 and is perpendicular to the second column 122 and the third column 123, and the tenth crossbeam 139 is connected between the first column 121 and the fourth column 124 and is perpendicular to the first column 121 and the fourth column 124, and both the ninth crossbeam 138 and the tenth crossbeam 139 are close to the top of the wooden frame 10; the first pressing member 16 and the second pressing member 17 are connected between the ninth crossbeam 138 and the tenth crossbeam 139 and can be raised and lowered along the height direction of the wooden frame 10, and the first pressing member 16 and the second pressing member 17 are along the second direction of the wooden frame 10 (i.e. Figure 1 and Figure 3 The second direction (as shown) is the interval setting.

[0057] Specifically, the ninth crossbeam 138 connects the second column 122 and the third column 123, and the tenth crossbeam 139 connects the first column 121 and the fourth column 124. Both the ninth and tenth crossbeams are close to the top of the wooden frame 10 and perpendicular to their respective columns 12. This significantly enhances the overall rigidity of the wooden frame 10, preventing damage to the wooden clamping structure 100 from external forces. The ninth and tenth crossbeams 138 and 139 work in conjunction with the crossbeams in the other crossbeam assembly 13, further improving the stability of the wooden frame 10. They cooperate with other crossbeams distributed along the height of the wooden frame 10, reinforcing the wooden frame 10 from different angles and positions, giving the entire wooden frame 10 stronger load-bearing capacity and resistance to deformation in all directions, forming a stable overall frame structure that provides a reliable support environment for internal components (such as the predetermined coil 300 and the predetermined iron core 200). The first clamping member 16 and the second clamping member 17 are connected between the ninth crossbeam 138 and the tenth crossbeam 139 and can be raised and lowered along the height direction of the wooden frame 10. This design allows the wooden clamping structure 100 to accommodate predetermined iron cores 200 and predetermined coils 300 at different heights. The first clamping member 16 and the second clamping member 17 are spaced apart along the second direction of the wooden frame 10. This arrangement can apply pressure evenly when clamping the predetermined iron cores 200 and predetermined coils 300, reducing the risk of movement due to the imbalance of force on the predetermined iron cores 200 and predetermined coils 300. The clearly defined connection positions of the ninth crossbeam 138 and the tenth crossbeam 139, as well as the relatively simple connection method between the first clamping member 16 and the second clamping member 17 and them, simplify the installation process of the wooden frame 10. The operator can clearly determine the installation position of each component. First, install the ninth crossbeam 138 and the tenth crossbeam 139, then connect the first clamping member 16 and the second clamping member 17 into place. Adjust the positions of the first clamping member 16 and the second clamping member 17 according to the actual height of the predetermined iron core 200 and the predetermined coil 300. This orderly installation process reduces installation difficulty and improves installation efficiency. The ninth crossbeam 138 and the tenth crossbeam 139 are positioned close to the top of the wooden frame 10, effectively utilizing the top space. They not only enhance the structural strength of the top of the frame but also provide an installation foundation for the first clamping member 16 and the second clamping member 17, ensuring full utilization of the top space of the wooden frame 10 without affecting the spatial layout of other parts within the accommodating cavity 11. This design improves the utilization rate of the entire wooden clamping structure's internal space while ensuring structural stability.

[0058] Further, see Figures 1 to 5As shown, the clamping assembly 15 includes multiple clamping beams 151, which are spaced apart along the first direction of the wooden frame 10. Each clamping beam 151 is connected between the first clamping member 16 and the second clamping member 17. The bottom surface of each clamping beam 151 is provided with a second guide groove 1511, which extends along the length of the clamping beam 151.

[0059] Specifically, the clamping assembly 15 consists of multiple clamping beams 151 spaced apart along the first direction of the wooden frame 10, with each clamping beam 151 connected between the first clamping member 16 and the second clamping member 17. This structure allows the clamping force to be applied evenly to the predetermined iron core 200 and the predetermined coil 300. Because the multiple clamping beams 151 are spaced apart, pressure concentration in localized areas is avoided, ensuring that the predetermined iron core 200 and the predetermined coil 300 are subjected to uniform force throughout the wooden frame 10. This effectively prevents component displacement and deformation caused by uneven localized force during the operation of equipment such as transformers, ensuring the stability of the predetermined iron core 200 and the predetermined coil 300, and maintaining the normal electromagnetic performance of the equipment. The number of clamping beams 151 can be adjusted reasonably according to needs and actual conditions. This embodiment shows the case of four clamping beams 151. The clamping beams 151 can not only clamp the predetermined coil 300 and the predetermined iron core 200, but also restrict the degree of freedom of the predetermined coil 300 and the predetermined iron core 200 in the first direction of the wooden frame 10, preventing the predetermined coil 300 and the predetermined iron core 200 from moving under the action of external force. The clamping beams 151 are connected between the first pressing member 16 and the second pressing member 17, which can be raised and lowered in the height direction, and work together with the first pressing member 16 and the second pressing member 17 to further enhance the clamping force on the predetermined iron core 200 and the predetermined coil 300. By adjusting the height of the first pressing member 16 and the second pressing member 17, the degree of clamping of the clamping beams 151 on the predetermined iron core 200 and the predetermined coil 300 can be flexibly controlled to adapt to the predetermined iron core 200 and the predetermined coil 300 of different specifications and different operating requirements, ensuring that they remain firmly fixed in the wooden frame 10 at all times. Each clamping beam 151 has a second guide groove 1511 extending along its length on its bottom surface, which facilitates the flow of transformer oil or air and helps dissipate heat from the predetermined coil 300 and the predetermined iron core 200. Multiple clamping beams 151 are spaced apart along the first direction of the wooden frame 10 between the first clamping member 16 and the second clamping member 17, achieving the clamping function while making efficient use of the vertical space inside the wooden frame 10. This layout does not excessively occupy space in other directions, leaving sufficient space for the rational arrangement of other components within the accommodating cavity 11 (such as the support assembly 14, the crossbeam assembly 13, etc.), improving the utilization rate of the internal space of the entire wooden clamping structure and contributing to a compact design. The clearly defined connection positions and spacing of the clamping beams 151 standardize the layout of the clamping assembly 15 within the wooden frame 10. This standardized layout, in conjunction with the layout of other components within the wooden frame 10, forms an orderly overall structure. The positional relationship between the various components is clearer, which makes it easier for installers to perform installation operations and also helps operators to quickly familiarize themselves with the structure and find and handle problems during later maintenance.During installation, the connection positions of the clamping beam 151 with the first clamping member 16 and the second clamping member 17 are clearly defined, allowing installers to easily install the clamping beam 151 to the designated position, reducing installation difficulty and improving installation efficiency. During maintenance, if a clamping beam 151 is damaged or the second guide channel 1511 needs cleaning, maintenance personnel can relatively easily disassemble, replace, or clean it, reducing maintenance time and costs and ensuring the wooden clamping structure can quickly return to normal operation.

[0060] Further, see Figure 1 , Figure 2 as well as Figure 5 As shown, the wooden frame 10 also includes a suspension member 18, and the predetermined iron core 200 includes a ring structure 210; the ring structure 210 is vertically arranged, the suspension member 18 is vertically connected between the fourth crossbeam 133 and the eighth crossbeam 137 and passes through the ring structure 210, and the suspension member 18 is close to the top of the predetermined iron core 200 and supported on the inner wall of the ring structure 210.

[0061] Specifically, the annular structure 210 of the predetermined iron core 200 is vertically arranged, and the suspension member 18 is vertically connected between the fourth crossbeam 133 and the eighth crossbeam 137 and passes through the annular structure 210, and is supported on its inner wall near the top of the predetermined iron core 200. This structure achieves precise positioning of the predetermined iron core 200 within the wooden frame 10. By passing through the annular structure 210, the suspension member 18 ensures that the predetermined iron core 200 is located in a specific position within the wooden frame 10, preventing it from shifting horizontally. At the same time, the support near the top provides stable vertical support for the predetermined iron core 200, bearing part of its weight, reducing the pressure on the bottom support assembly 14, helping to maintain the vertical state of the predetermined iron core 200, ensuring its stability during operation, and thus ensuring the normal electromagnetic performance of equipment such as transformers. The connection between the suspension member 18 and the fourth crossbeam 133 and the eighth crossbeam 137 allows it to work in conjunction with the frame structure of the entire wooden frame 10. The fourth crossbeam 133 and the eighth crossbeam 137 provide lateral support and fixation for the suspension component 18, enhancing its stability and thus better supporting the predetermined iron core 200. This synergistic effect enables the wooden frame 10 to more effectively protect the predetermined iron core 200 from external vibrations and impacts, preventing it from shifting or being damaged due to external forces, and ensuring the reliable operation of equipment such as transformers.

[0062] Further, see Figure 1 , Figure 2 as well as Figure 5 As shown, a limiting port 181 is provided on the suspension member 18, and the limiting port 181 is along the length direction of the suspension member 18 (i.e., Figure 1Extending in the second direction shown, the suspension member 18 is engaged with the inner wall of the predetermined iron core 200 through the limiting port 181.

[0063] Specifically, the limiting opening 181 extending along the length of the suspension member 18 engages with the inner wall of the predetermined iron core 200, providing precise positioning for the predetermined iron core 200. This engagement method restricts the horizontal displacement of the predetermined iron core 200, ensuring its fixed position within the wooden frame 10. The limiting opening 181 engaging with the inner wall of the predetermined iron core 200 not only limits horizontal movement but also improves the vertical stability of the predetermined iron core 200. It increases the friction and contact area between the suspension member 18 and the predetermined iron core 200, allowing the suspension member 18 to better support the weight of the predetermined iron core 200, reducing the possibility of vertical movement of the predetermined iron core 200, and further ensuring the stable placement of the predetermined iron core 200 within the wooden frame 10.

[0064] Further, see Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the wooden frame 10 also includes a plurality of reinforcing members 191, which are disposed between the first crossbeam 130 and the second crossbeam 131, between the second crossbeam 131 and the third crossbeam 132, between the third crossbeam 132 and the fourth crossbeam 133, between the fifth crossbeam 134 and the sixth crossbeam 135, between the sixth crossbeam 135 and the seventh crossbeam 136, and between the seventh crossbeam 136 and the eighth crossbeam 137.

[0065] Specifically, multiple reinforcing members 191 are installed between the crossbeams, such as between the first crossbeam 130 and the second crossbeam 131, and between the second crossbeam 131 and the third crossbeam 132. These reinforcing members 191 can enhance the structural strength of the wooden frame 10 in localized areas. When the wooden frame structure is subjected to external forces, such as bumps during transportation or collisions at the installation site, the reinforcing members 191 can disperse the stress between the crossbeams, preventing stress concentration on a single crossbeam and thus preventing deformation or damage due to excessive stress. The multiple reinforcing members 191 work together to improve the overall strength of the wooden frame 10. Together with the crossbeams, columns 12, and other components, they form a stable frame structure, enabling the wooden frame 10 to better withstand external forces in all directions. The installation of the reinforcing members 191 is like adding extra support points to the frame structure, making the entire structure more robust and durable, providing a more reliable support environment for the internal predetermined iron core 200 and predetermined coil 300, and ensuring the stable operation of equipment such as transformers under various operating conditions. The reinforcing member 191 connects adjacent crossbeams, effectively limiting the relative displacement between them, reducing the deformation of the crossbeams under stress, maintaining the relative positional stability between them, ensuring the shape and dimensional stability of the accommodating cavity 11, and thus guaranteeing the installation position accuracy of the predetermined iron core 200 and predetermined coil 300. This prevents the internal components from shifting due to crossbeam deformation, which could affect the performance of transformers and other equipment. The presence of the reinforcing member 191 significantly enhances the rigidity between the crossbeams. Increased rigidity means that the wooden frame 10 can better maintain its shape and structural integrity when subjected to external forces. Because the reinforcing member 191 disperses the stress borne by the crossbeams, it reduces fatigue damage to the crossbeams during long-term use. During equipment operation, the crossbeams are constantly subjected to various external forces. Without the reinforcing member 191, the crossbeams may gradually develop fatigue cracks due to repeated stress, eventually leading to structural damage. The reinforcing member 191 effectively reduces this risk, extends the service life of the crossbeams and the entire wooden frame 10, reduces the number of repairs and replacements required due to structural damage, and lowers equipment maintenance costs.

[0066] Optionally, the wooden frame 10 also includes a top abutment 192, which is disposed on the top of the wooden frame 10 and fixedly connected to the wooden frame 10, and extends along the height direction of the wooden frame 10.

[0067] Specifically, the abutment 192 is disposed on the top of the wooden frame 10 and extends along the height direction, and is fixedly connected to the wooden frame 10. This provides additional vertical support to the top of the wooden frame 10, while also ensuring the stability of the wooden frame 10 during operation. The abutment 192 works in conjunction with other components of the wooden frame 10, such as the uprights 12 and the crossbeam assembly 13, to jointly enhance the overall stability of the wooden frame 10. It cooperates with the top crossbeam to make the top frame structure more robust and further disperse the effect of external forces on the wooden frame 10. For example, when the wooden frame 10 is subjected to lateral forces, the abutment 192 can assist the crossbeam in converting part of the lateral forces into vertical forces, which are then transmitted to the ground through the uprights. This enhances the wooden frame 10's ability to resist external forces in all directions, ensuring that the internal components remain stable under various working conditions. The installation of the abutment 192 is relatively simple, and its fixed connection to the top of the wooden frame 10 is clearly defined. When installing the wooden frame 10, operators can easily install the abutment 192 after the top frame is erected. For example, the abutment 192 can be fixed to the top structure using common connection methods such as bolts and mortise and tenon joints, reducing installation difficulty and improving efficiency. During maintenance, if the abutment 192 is damaged or needs inspection, its relatively independent design and easily accessible location at the top allow maintenance personnel to easily disassemble, replace, or inspect it. This reduces maintenance time and costs, ensuring the wooden clamp structure can quickly return to normal operation. For example, during regular maintenance, operators can quickly check the connection of the abutment 192 for security and signs of damage, promptly identifying and addressing potential problems. The abutment 192 allows the wooden frame 10 to adapt to different working conditions. For applications that may experience significant top pressure or impact, such as outdoor transformers facing strong winds or falling objects, the abutment 192 enhances the protective capabilities of the top of the wooden frame 10, ensuring safe equipment operation. For wooden frames 10 of different specifications and sizes, the abutment 192 can be adjusted and customized according to the actual situation, which improves the adaptability of the wooden clamp structure to different working conditions and equipment requirements.

[0068] On the other hand, this application also provides a transformer (not shown in the figure), which may be, for example, an oil-immersed transformer or a dry-type transformer, and the transformer includes the aforementioned wooden clamping structure.
