[0002] In the overall construction and operation system of a substation, the main transformer structure serves as the infrastructure that ensures the stable output of electrical equipment and the safe transmission of power. The rationality of its structural design is directly related to the space utilization rate, engineering construction cost, and land resource consumption of the substation.

[0003] Currently, the main transformer frame generally adopts the A-frame column scheme, which is a structural form that combines single-span or multi-span A-frame columns with frame beams arranged in a straight line, according to the needs of electrical outgoing lines. This type of main transformer frame utilizes the mechanical properties of the A-frame columns to effectively bear the loads of the frame beams and subsequent electrical outgoing line equipment, meeting the requirements of "I"-shaped electrical outgoing lines.

[0004] However, in the actual construction of substations, due to the influence of site topography, surrounding environment, and overall layout planning of electrical systems, vertical outgoing lines are also very common. When faced with the need for vertical electrical outgoing line schemes, two mutually perpendicular main transformer frames are usually set up to match the vertical outgoing line requirements.

[0005] Regarding the above technical solutions, when two adjacent spans of the frame are arranged vertically, a large number of frame columns are required.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] To better understand the main transformer frame and system provided in this utility model embodiment, its application background is first introduced. The main transformer frame is a metal frame in a substation used to support and fix the main transformer and related conductors and electrical equipment. It is an important facility to ensure safe and stable power transmission.

[0032] Currently, the main transformer frame generally adopts the A-frame column scheme, which is a structural form that combines single-span or multi-span A-frame columns and frame beams arranged in a straight line. Utilizing the mechanical properties of the A-frame columns, it bears the load of the frame beams and subsequent electrical outgoing equipment, thus satisfying the "I"-shaped electrical outgoing line scheme. When the electrical outgoing line scheme is vertical, two vertical main transformer frames are generally installed to match the vertical outgoing line requirements.

[0033] Regarding the above technical solutions, when two adjacent spans of the frame are arranged vertically, a large number of frame columns are required. This not only increases the amount of building materials such as steel, thus increasing the construction cost and complexity of the project, but also occupies a large land area, which is not conducive to the effective use of land resources.

[0034] In view of the above problems, this utility model provides a main transformer frame and system that can reduce the number of frame columns, thereby reducing the amount of building materials used, reducing the construction cost and complexity of the project, and at the same time reducing the land occupation area, thus realizing the effective use of land resources.

[0035] The following is combined Figures 1 to 9 This invention describes the main transformer architecture and system.

[0036] Reference Figure 1 A main structural frame includes structural columns 10 and structural beams 20. The structural columns 10 include first structural columns 11 and second structural columns 12. Two first structural columns 11 are spaced apart in a first direction, and the second structural column 12 is spaced apart from one of the first structural columns 11 in a second direction. The first direction is perpendicular to the second direction, and the height of the second structural column 12 is lower than that of the first structural column 11. The structural beams 20 include first structural beams 21 and second structural beams 22. Both ends of the first structural beam 21 are fixedly connected to the two first structural columns 11, and one end of the second structural beam 22 is fixedly connected to the first structural column 11, and the other end is fixedly connected to the second structural column 12.

[0037] In practical applications, two first frame columns 11 arranged along the first direction form a two-way lateral resisting system. Combined with the first frame beam 21 connecting the two, the outgoing line requirements in one direction can be met. Similarly, the first frame columns 11 and the second frame columns 12 arranged along the second direction form a two-way lateral resisting system. Combined with the second frame beam 22 connecting the two, the outgoing line requirements in the other vertical direction can be met.

[0038] Compared to related technologies, this method utilizes two first frame columns 11 arranged along the first direction to form a support system in the first direction, and uses one first frame column 11 and one second frame column 12 arranged along the second direction to form a vertical support system in the second direction. The two support systems share one first frame column 11, which can reduce the amount of one frame column 10 used in the second direction, thereby reducing the amount of building materials used, lowering the construction cost and complexity of the project. At the same time, the two support systems share a single-sided support point, which can reduce the waste of right-angle areas caused by the independent occupation of two traditional frames, reduce the land area, and achieve effective use of land resources.

[0039] It should be clarified here that the main difference between the first frame column 11 and the second frame column 12 lies in their height, which is used to form a support system with different heights in the vertical direction. However, in terms of their main structure and function, they are basically the same. In addition, in the main transformer frame, the dimensions and specifications of each frame column 10 and frame beam 20 need to be adapted to the actual application scenario. No specific limitations are made in this embodiment of the utility model.

[0040] In one example of this utility model, the frame column 10 is an overall steel frame structure, which includes two or more supporting columns. For ease of understanding and description, refer to... Figures 1 to 3 The support column includes a first support column 101 and a second support column 102. The first support column 101 and the second support column 102 are arranged opposite to each other and their top ends are fixedly connected to form a herringbone structure.

[0041] In detail, the support column can adopt a composite steel pipe structure, with adjacent steel pipe sections connected by flanges. This design ensures bending strength while reducing the overall weight of the frame column 10, facilitating construction.

[0042] In one example of this invention, the plane formed by the first support column 101 and the second support column 102 between the two first frame columns 11 is arranged in parallel, and in the second frame column 12, the herringbone plane formed by the first support column 101 and the second support column 102 faces the first frame column 11. This arrangement ensures that the frame columns 10 are subjected to uniform force and avoids lateral torsion.

[0043] To further ensure stability, the first frame column 11 connected to the second frame column 12 also includes a third support column 103. The top of the third support column 103 is fixedly connected to the tops of the first support column 101 and the second support column 102, specifically by means of a stirring pin or a pin connection. Furthermore, the third support column 103 is set at an angle to the plane formed by the first support column 101 and the second support column 102. The projection of the third support column 103 onto the aforementioned plane is located between the first support column 101 and the second support column 102, or more specifically, in the middle of the two.

[0044] With this configuration, the tops of the first support column 101, the second support column 102, and the third support column 103 intersect and are fixed to form a triangular pyramid structure, which increases spatial constraints, further improves the ability of the first frame column 11 to resist lateral torsional forces and structural strength, and can distribute the load, reduce the load on a single column, thereby providing stable support for the two support systems in the first and second directions at the same time.

[0045] In addition, the arrangement of the third support column 103 can provide another optional connection position for the second frame beam 22. Specifically, when a herringbone structure is adopted, on the vertical side, the second frame beam 22 can only be connected to one of the support columns of the first frame column 11. If the positions do not match, it may be necessary to adjust the direction of the second frame beam 22, which will increase the construction difficulty and construction cost. After the third support column 103 is arranged, the second frame beam 22 can be connected to the third support column 103 according to the actual working conditions, which improves the applicability.

[0046] To ensure the structural stability of the frame column 10, in a further example of this utility model, refer to... Figure 3 and Figure 4 The frame column 10 also includes at least one connector 13 for connecting multiple support columns.

[0047] In detail, the connector 13 includes a connecting post 131, which is arranged between two adjacent support posts, and the two ends of the connecting post 131 are fixedly connected to the adjacent support posts respectively.

[0048] Understandably, the structural form of the connector 13 will vary depending on the specific structure of the frame column 10. For example, when the frame column 10 only includes the first support column 101 and the second support column 102, one connector 131 is provided, with its two ends fixedly connected to the first support column 101 and the second support column 102 respectively; when the frame column 10 includes the first support column 101, the second support column 102 and the third support column 103, three connector 131 are provided, and the three connector 131 are respectively arranged between the first support column 101 and the second support column 102, between the first support column 101 and the third support column, and between the second support column 102 and the third support column 103, forming a triangular arrangement.

[0049] Furthermore, when there are multiple connectors 13, the multiple connectors 13 are arranged at intervals along the height direction of the frame column 10 to further improve the structural strength and stability of the frame column 10.

[0050] More specifically, the connector 13 also includes a connecting plate 132 and first stiffening ribs 133. The connecting plate 132 is fixedly connected to the support column, for example, by welding. The end of the connecting column 131 is supported on the connecting plate 132 and fixedly connected to it by bolts or other connecting components. Multiple first stiffening ribs 133 are provided and arranged around the support column. One side of each first stiffening rib 133 is welded to the connecting plate 132, and the adjacent side is welded to the support column. This arrangement provides a connection foundation for the connecting column 131 through the connecting plate 132, improving construction convenience. The first stiffening ribs 133 enhance the stability of the connection between the connecting plate 132 and the support column, thereby increasing the connection strength between the connecting column 131 and the support column.

[0051] To facilitate the connection of the frame beam 20, in one example of this utility model, referring to... Figure 3 and Figure 5 The top of the frame column 10 is fixedly provided with an end support 14. Both ends of the first frame beam 21 are fixedly connected to the end supports 14 of the two first frame columns 11 respectively. A support 15 is fixedly provided on the first frame column 11. The support 15 corresponds in height to the end support 14 of the second frame column 12. One end of the second frame beam 22 is fixedly connected to the support 15, and the other end is fixedly connected to the end support 14 of the second frame column 12. In this configuration, the end supports 14 and the support 15 provide a connection foundation for the first frame beam 21 and the second frame beam 22.

[0052] In a further example of this utility model, the end support 14 includes an end support plate 141 and a second stiffening rib 142; wherein, the end support plate 141 is fixedly connected to the top end of the frame column 10, for example, the end support plate 141 can be welded and fixed to the top end of the first support column 101 and the second support column 102 at the same time; multiple second stiffening ribs 142 are provided, and multiple second stiffening ribs 142 are arranged around the first support column 101 and the second support column 102. One side of the second stiffening rib 142 is welded and fixed to the end support plate 141, and the adjacent other side is welded and fixed to the first support column 101 or the second support column 102, thereby ensuring the structural strength of the connection between the end support 14 and the frame column 10.

[0053] In detail, the end support plate 141 is provided with connection holes, and the first frame beam 21 and the second frame beam 22 are connected to the connection holes on the end support plate 141 by bolts and other connecting components, thereby realizing the connection and fixation of the first frame beam 21 and the second frame beam 22 on the frame column 10.

[0054] It is understood that, depending on the overall layout of the electrical system, the receiving component 15 may be installed on at least one of the first support column 101, the second support column 102, and the third support column 103. No specific restrictions are imposed in this embodiment of the utility model.

[0055] For ease of understanding, please refer to Figure 6 and Figure 7 In this embodiment of the invention, the receiving member 15 fixed to the first support column 101 is used as an example for explanation. In this embodiment, the receiving member 15 includes a receiving plate 151 and third stiffening ribs 152; wherein the receiving plate 151 is fixedly connected to the first support column 101; and multiple third stiffening ribs 152 are provided and connected around the first support column 101. This ensures the structural strength of the connection between the receiving member 15 and the frame column 10.

[0056] In detail, the receiving plate 151 is provided with connection holes, and the second frame beam 22 is connected to the connection holes on the receiving plate 151 through bolts and other connecting components, thereby realizing the connection and fixation between the second frame beam 22 and the first frame column 11.

[0057] The specific structure of the frame beam 20 will be described in detail below with reference to the attached drawings.

[0058] It is understandable that the first frame beam 21 and the second frame beam 22 can adopt the same structural form or different structural forms, depending on the construction scenario.

[0059] In this embodiment, both the first frame beam 21 and the second frame beam 22 are steel structure beams, and they adopt the same structural form. The difference between them lies in their different size specifications.

[0060] In detail, refer to Figure 8 and Figure 9 The frame beam 20 includes a main beam 201 and connecting beams 202. There are three main beams 201, which are arranged in the same direction and in a triangular arrangement. There are multiple connecting beams 202, which are arranged in groups between each pair of adjacent main beams 201. The connecting beams 202 are arranged at an angle to the main beams 201 and their ends are fixedly connected to the two main beams 201 respectively. In the extension direction of the main beams 201, the end of the upstream main beam 201 and the beginning of the downstream main beam 201 in each group are connected to the same main beam 201, so that the adjacent two connecting beams 202 and the main beams 201 form a triangular or trapezoidal structure. In the length direction of the main beams 201, the multiple connecting beams 202 are arranged in a wave-like pattern.

[0061] To elaborate further, the three main beams 201 are arranged in an acute triangle, and the connecting beam 202 is welded and fixed to the main beams 201.

[0065] The main frame and system provided by this utility model embodiment utilize two first frame columns 11 arranged along the first direction to form a support system in the first direction, and utilize one first frame column 11 and one second frame column 12 arranged along the second direction to form a vertical support system in the second direction. The two support systems share one first frame column 11, which can reduce the amount of one frame column 10 used in the second direction, thereby reducing the amount of building materials used, reducing the construction cost and construction complexity of the project. At the same time, the two support systems share a single-sided support point, which can reduce the waste of right-angle areas caused by the independent occupation of two traditional frames, reduce the land area, and realize the effective use of land resources.
