Description

Technical Field

[0001] This invention relates to the field of power transmission and transformation technology, and in particular to a substation architecture. Background Technology

[0002] As one of the main pieces of equipment in a substation, the substation frame is used to suspend conductors, support conductors, or switchgear and other electrical equipment.

[0003] The crossbeams in existing substation frames are typically spliced ​​together in a straight line. When the load at the mounting points is large, the dimensions of these straight crossbeams need to be designed to be larger. This not only results in a heavier product, further increasing the bending moment load at the mounting points, but also, under excessively demanding operating conditions, this design can easily lead to excessive offset at the mounting points, failing to meet the substation frame design standards. Furthermore, it can cause excessive stress on the bolts at the flange connections, leading to failure. In addition, the oversized straight crossbeams also increase product costs, limiting the widespread adoption of substation frames.

[0004] Therefore, in order to solve the above problems, a new substation architecture must be designed. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides a substation frame, comprising: a support assembly including a first support member and a second support member spaced apart along a first direction; a middle crossbeam disposed between the first support member and the second support member, the middle crossbeam including a first end and a second end opposite to each other along the first direction; and a connecting crossbeam including a first connecting portion and a second connecting portion, the first connecting portion connecting the first end and the first support member, and the second connecting portion connecting the second end and the second support member; wherein the first connecting portion and the first support member form a triangle with the first end as the vertex, and the second connecting portion and the second support member form a triangle with the second end as the vertex.

[0006] As a further improvement of the present invention, the first connecting part and the second connecting part are symmetrically arranged at both ends of the middle crossbeam, and in the direction from the support component to the middle crossbeam, both the first connecting part and the second connecting part are inclined upward.

[0007] As a further improvement of the present invention, both the first connecting part and the second connecting part include a connecting body and a joint structure connecting the connecting body and the intermediate crossbeam; wherein, the joint structure and the connecting body, and the joint structure and the intermediate crossbeam are all flange connections.

[0008] As a further improvement of the present invention, both ends of the intermediate crossbeam are fitted with first flanges, and the joint structure near the end of the intermediate crossbeam is formed with a second flange. The first flange and the second flange are fixedly connected by a first fastener.

[0009] As a further improvement of the present invention, the connecting body includes a first sub-connecting segment and a second sub-connecting segment. In the direction from the support component to the intermediate crossbeam, the first sub-connecting segment and the second sub-connecting segment gradually approach each other. A third flange is sleeved and fixed at the end of the first sub-connecting segment and the second sub-connecting segment near the joint structure. The joint structure includes a first sub-joint segment and a second sub-joint segment. In the direction from the support component to the intermediate crossbeam, the first sub-joint segment and the second sub-joint segment gradually approach each other. The first sub-joint segment connects to the first sub-connecting segment, and the second sub-joint segment connects to the second sub-connecting segment. A fourth flange is formed at the end of the first sub-joint segment and the second sub-joint segment near the connecting body. The third flange and the fourth flange are fixedly connected by a second fastener.

[0010] As a further improvement of the present invention, the first support member and the second support member are symmetrically arranged. Both the first support member and the second support member include a first sub-support segment and a second sub-support segment. In the direction from bottom to top, the first sub-support segment and the second sub-support segment gradually approach each other. The first sub-connecting segment is fixedly connected to the first sub-support segment, and the second sub-connecting segment is fixedly connected to the second sub-support segment.

[0011] As a further improvement of the present invention, the first sub-support section protrudes toward the first sub-connecting section and forms a first protrusion, the first protrusion forming a fifth flange, and a sixth flange is sleeved and fixed at one end of the first sub-connecting section near the first sub-support section, the fifth flange and the sixth flange being fixedly connected by a third fastener; the second sub-support section protrudes toward the second sub-connecting section and forms a second protrusion, the second protrusion forming a seventh flange, and an eighth flange is sleeved and fixed at one end of the second sub-connecting section near the second sub-support section, the seventh flange and the eighth flange being fixedly connected by a fourth fastener.

[0012] As a further improvement of the present invention, both the connecting beam and the intermediate beam are composite post insulators.

[0013] As a further improvement of the present invention, the intermediate crossbeam is provided with a hanging part for suspending the wire. The hanging part includes a first hanging plate and a second hanging plate. The first hanging plate is fixedly disposed between the first connecting part and the intermediate crossbeam, and the second hanging plate is fixedly disposed between the second connecting part and the intermediate crossbeam.

[0014] As a further improvement of the present invention, the intermediate crossbeam includes several sub-crossbeams connected end to end, and the hanging part also includes a third hanging plate disposed between two adjacent sub-crossbeams.

[0015] The beneficial effects of this invention are as follows: Unlike existing technologies, this invention forms a triangle with the first end of the intermediate crossbeam as its vertex by the first connecting part and the first supporting member, and a triangle with the second end of the intermediate crossbeam as its vertex by the second connecting part and the second supporting member. On one hand, because the triangular structure is more stable, and the connecting crossbeam can bear the lateral, longitudinal, and vertical loads at the mounting points, the strength and stiffness of the substation frame structure provided by this invention are improved. This effectively controls the actual offset at each mounting point under operating conditions, solving the problem of excessive offset at the mounting points in existing technologies, which prevents the substation frame from meeting design standards. On the other hand, the stable triangular structure allows for further miniaturization of the connecting crossbeam specifications, reducing manufacturing costs. Furthermore, compared to the straight crossbeam in existing technologies, the combined structure of the intermediate crossbeam and connecting crossbeam provided by this invention further reduces the impact of its own weight, thereby effectively reducing the vertical load introduced by its own weight. In addition, because the substation frame provided by this invention has increased structural stiffness and reduced offset, it effectively ensures the reliability of the force at each connection point of the substation frame, thus ensuring the operational reliability of the entire substation frame.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 6 The present invention provides a substation frame 100, including a support component 110, an intermediate crossbeam 120 and a connecting crossbeam 130.

[0026] The support assembly 110 includes a first support member 111 and a second support member 112 spaced apart along a first direction; a middle crossbeam 120 is disposed between the first support member 111 and the second support member 112, and includes a first end 121 and a second end 122 opposite to each other along the first direction; a connecting crossbeam 130 includes a first connecting portion 131 and a second connecting portion 132, the first connecting portion 131 connecting the first end 121 and the first support member 111, and the second connecting portion 132 connecting the second end 122 and the second support member 112. Furthermore, the first connecting portion 131 and the first support member 111 form a triangle with the first end 121 as the vertex, and the second connecting portion 132 and the second support member 112 form a triangle with the second end 122 as the vertex.

[0027] Therefore, unlike the prior art, the present invention forms a triangle with the first connecting part 131 and the first support member 111 forming a triangle with the first end 121 of the intermediate crossbeam 120 as the vertex, and a triangle with the second connecting part 132 and the second support member 112 forming a triangle with the second end 122 of the intermediate crossbeam 120 as the vertex. On the one hand, because the triangular structure is more stable, and the connecting crossbeam 130 can bear the lateral, longitudinal, and vertical loads at the suspension point, the strength and stiffness of the substation frame 100 structure provided by the present invention are improved. This effectively controls the actual offset at each suspension point under operating conditions, thereby solving the problem of substation frame suspension point offset in the prior art. The excessive displacement leads to the inability to meet design standards. On the other hand, the triangular structure allows for further miniaturization of the connecting beam 130, reducing manufacturing costs. Furthermore, compared to the straight beam in the prior art, the combined structure of the intermediate beam 120 and the connecting beam 130 provided by this invention further reduces the impact of the substation frame 100's self-weight, thereby effectively reducing the vertical load introduced by its self-weight. In addition, due to the increased structural stiffness and reduced offset of the substation frame 100 provided by this invention, the stress reliability of each connection of the substation frame 100 is effectively guaranteed, thus ensuring the operational reliability of the entire substation frame 100.

[0028] Furthermore, in this embodiment, the first connecting portion 131 and the second connecting portion 132 are symmetrically arranged at both ends of the intermediate crossbeam 120. In the direction from the support assembly 110 to the intermediate crossbeam 120, both the first connecting portion 131 and the second connecting portion 132 are inclined upwards. Specifically, in the direction from the first support member 111 to the first end 121 of the intermediate crossbeam 120, the first connecting portion 131 is inclined upwards; in the direction from the second support member 112 to the second end 122 of the intermediate crossbeam 120, the second connecting portion 132 is inclined upwards. Therefore, by raising the vertical distance between the intermediate crossbeam 120 and the ground, even if the intermediate crossbeam 120 experiences a vertical offset after suspending the conductor, it will not fail to meet design standards due to excessive conductor suspension point offset under excessive operating conditions. Furthermore, compared to the existing structure where a straight crossbeam directly connects to the support assembly 110, the first connecting part 131 and the second connecting part 132 in the substation frame 100 provided by this invention replace the straight crossbeams on both sides in the prior art. Moreover, due to the stable triangular structure formed by the support assembly 110 and the connecting crossbeam 130, the connecting crossbeam 130 can be miniaturized. At the same time, both the first connecting part 131 and the second connecting part 132 can effectively bear the lateral, longitudinal, and vertical loads at the suspension point. When the load at the suspension point is large, the substation frame 100 provided by this invention has a better effect in reducing the impact of self-weight, thereby further reducing the vertical load introduced by self-weight.

[0029] To achieve the connection between the first connecting part 131, the second connecting part 132, and the intermediate crossbeam 120, both the first connecting part 131 and the second connecting part 132 include a connecting body 133 and a joint structure 134 connecting the connecting body 133 and the intermediate crossbeam 120, so as to achieve a stable connection between the connecting body 133 and the intermediate crossbeam 120 through the joint structure 134. Specifically, in this embodiment, the joint structure 134 is flange-connected to the intermediate crossbeam 120, and the joint structure 134 is also flange-connected to the connecting body 133. By using the flange connection, not only is a stable connection between the joint structure 134 and the intermediate crossbeam 120 and between the joint structure 134 and the connecting body 133 achieved, but installation and disassembly are also very convenient, facilitating maintenance and replacement.

[0030] Of course, in other embodiments of the present invention, the joint structure 134 and the intermediate crossbeam 120, and the joint structure 134 and the connecting body 133 may also adopt other connection methods, such as welding, as long as the purpose of achieving a stable connection between the joint structure 134 and the intermediate crossbeam 120, and the joint structure 134 and the connecting body 133 is achieved, the purpose of the present invention can be achieved.

[0031] like Figure 1 and Figure 4As shown, in order to achieve a stable connection between the intermediate crossbeam 120 and the joint structure 134, in this embodiment, both ends of the intermediate crossbeam 120 are fitted with a first flange 123, and the end of the joint structure 134 near the intermediate crossbeam 120 is formed with a second flange 1341. The first flange 123 and the second flange 1341 are fixedly connected by a first fastener (not shown).

[0032] Specifically, in one embodiment, the first flange 123 includes a first sleeve 1231 and a first flange 1232, with the first sleeve 1231 fitted onto the end of the intermediate crossbeam 120. Further, as... Figure 5 As shown, the first flange 1232 includes a disc-shaped first main body 12321, a first inclined hanging part 12322 and a second inclined hanging part 12323 connected to the lower end of the first main body 12321. The first inclined hanging part 12322 and the second inclined hanging part 12323 are provided with hanging holes for suspending wires. That is, in this embodiment, the first main body 12321, the first inclined hanging part 12322 and the second inclined hanging part 12323 are integrally formed. Of course, in other embodiments, the first inclined hanging part 12322 and the second inclined hanging part 12323 for suspending wires can also be provided on the second flange 1341, or the first flange 1232 can be directly set as a disc, and the second flange 1341 can also be directly set as a disc, with an additional hanging plate for suspending wires provided between the first flange 1232 and the second flange 1341. The hanging plate is fixed between the first flange 1232 and the second flange 1341, which can also achieve the purpose of this invention. Furthermore, the first main body 12321 includes a first plate and a second plate disposed opposite to each other.

[0033] In this embodiment, the second flange 1341 is also disc-shaped and includes a third and a fourth disc surface arranged opposite to each other. The third disc surface of the second flange 1341 is tightly fixed to the first disc surface of the first main body 12321, and the fourth disc surface of the second flange 134 is connected to one end of the joint structure 134 near the intermediate crossbeam 120. The first disc surface of the first flange 1232 and the third disc surface of the second flange 1341 are provided with the same first mounting holes (not shown). The first fasteners are bolts and nuts that fit together, and are fastened to the first flange 1232 and the second flange 1341 through the first mounting holes. In addition, in this embodiment, a number of first reinforcing ribs 1233 are provided on the outer circumferential surface of the first sleeve 1231 of the first flange 123 to increase the strength of the first flange 123 and ensure its sufficient mechanical properties. At the same time, both the first flange 123 and the second flange 1341 are metal flanges and can be made of materials such as aluminum, iron, and stainless steel.

[0034] In addition, such as Figure 1 , Figure 4 and Figure 6As shown, in order to achieve a stable connection between the connecting body 133 and the joint structure 134, in one embodiment, the connecting body 133 includes a first sub-connecting segment 1331 and a second sub-connecting segment 1332. In the direction from the support assembly 110 to the intermediate crossbeam 120, the first sub-connecting segment 1331 and the second sub-connecting segment 1332 gradually approach each other. A third flange 1333 is sleeved and fixed at the end of the first sub-connecting segment 1331 and the second sub-connecting segment 1332 closest to the joint structure 134. Correspondingly, the joint structure 134 includes a first sub-connecting head segment 1342 and a second sub-connecting head segment 1343. In the direction from the support assembly 110 to the intermediate crossbeam 120, the first sub-connecting head segment 1342 and the second sub-connecting head segment 1343 gradually approach each other and are simultaneously connected to the fourth disc surface of the second flange 1341. The first sub-connecting head section 1342 is connected to the first sub-connecting head section 1331, and the second sub-connecting head section 1343 is connected to the second sub-connecting head section 1332. A fourth flange 1344 is formed at the end of both the first and second sub-connecting head sections 1342 and 1343 near the connecting body 133. Furthermore, the third flange 1333 and the fourth flange 1344 are fixedly installed using a second fastener (not shown).

[0035] Specifically, the third flange 1333 includes a third sleeve 13331 and a disc-shaped third flange 13332. The third sleeve 13331 is sleeved on the ends of the first sub-connecting section 1331 and the second sub-connecting section 1332 near the joint structure 134. Furthermore, the third flange 13332 includes a fifth and a sixth disc face arranged opposite to each other. The fourth flange 1344 is disc-shaped and includes a seventh and an eighth disc face arranged opposite to each other. The fifth disc face of the third flange 13332 is tightly fitted and fixed to the seventh disc face of the fourth flange 1344. The fifth disc face of the third flange 13332 and the seventh disc face of the fourth flange 1344 are provided with the same second mounting holes (not shown). The second fasteners achieve the fastening installation of the first sub-connecting section 1331 and the first sub-connecting head section 1342, and the second sub-connecting section 1332 and the second sub-connecting head section 1343, respectively, through the second mounting holes. Furthermore, the second fastener is also a bolt and nut that fit together.

[0036] To enhance the strength of the third flange 1333 and the fourth flange 1344, several third reinforcing ribs 13333 are provided on the outer circumferential surface of the third sleeve 13331, and several fourth reinforcing ribs 1345 are provided circumferentially on the eighth disc surface of the fourth flange 1344, thereby increasing the strength of the third flange 1333 and the fourth flange 1344. Of course, the third reinforcing ribs 13333 and the fourth reinforcing ribs 1345 can also be selectively provided as needed, for example... Figure 5As shown, both third flanges 1333 are provided with third reinforcing ribs 13333, and one of the two fourth flanges 1344 is provided with a fourth reinforcing rib 1345, all of which are within the protection scope of this invention. Furthermore, both the third flanges 1333 and the fourth flanges 1344 are metal flanges, which can be made of materials such as aluminum, iron, or stainless steel. It should be noted that the flange structure of the first sub-connecting section 1331 near the joint structure 134 and the flange structure of the second sub-connecting section 1332 near the joint structure 134 in the above embodiment are the same flange structure, i.e., both are third flanges 1333; correspondingly, the flange structure of the first sub-connecting head section 1342 near the connecting body 133 and the flange structure of the second sub-connecting head section 1343 near the connecting body 133 are also the same flange structure, i.e., both are fourth flanges 1344.

[0037] In another embodiment, the flange structure of the first sub-connecting segment 1331 near the end of the joint structure 134 and the flange structure of the second sub-connecting segment 1332 near the end of the joint structure 134 can also be different flange structures, such as a first sub-flange and a second sub-flange respectively; correspondingly, the flange structure of the first sub-connecting head segment 1342 near the end of the connecting body 133 and the flange structure of the second sub-connecting head segment 1343 near the end of the connecting body 133 can also be different flange structures, such as a third sub-flange and a fourth sub-flange respectively. The first sub-flange and the third sub-flange are fixedly connected, and the second sub-flange and the fourth sub-flange are fixedly connected, which can also achieve the purpose of the present invention.

[0038] In addition, such as Figure 1 and Figure 3As shown, the first support member 111 and the second support member 112 are symmetrically arranged. Both the first support member 111 and the second support member 112 include a first sub-support segment 113 and a second sub-support segment 114. From bottom to top, the first sub-support segment 113 and the second sub-support segment 114 gradually approach each other. A first sub-connecting segment 1331 is fixedly connected to the first sub-support segment 113, and a second sub-connecting segment 1332 is fixedly connected to the second sub-support segment 114. Through this arrangement, a stable support structure is formed between the first sub-support segment 113 and the second sub-support segment 114, enabling the support assembly 110 to provide stable support. Of course, in other embodiments of the present invention, the support assembly 110 can also be configured in other shapes, such as a triangle, as long as it achieves the function of stable support, the purpose of the present invention can be realized. Furthermore, in a specific embodiment of the present invention, both the first support member 111 and the second support member 112 further include a connecting sub-support section 115 connecting the upper ends of the first sub-support section 113 and the second sub-support section 114, and both the first sub-support section 113 and the second sub-support section 114 can be a single continuous support body or composed of multiple support sections spliced ​​together. It should be noted that both the first support member 111 and the second support member 112 are made of iron, but other metal materials are also possible.

[0039] Furthermore, in order to achieve a stable connection between the connecting beam 130 and the support assembly 110, the first sub-support section 113 protrudes towards the first sub-connecting section 1331 to form a first protrusion 1131, the first protrusion 1131 forms a fifth flange 1132, and a sixth flange 1334 is sleeved and fixed at one end of the first sub-connecting section 1331 near the first sub-support section 113. The fifth flange 1132 and the sixth flange 1334 are fixedly connected by a third fastener (not shown). Specifically, the fifth flange 1132 is disc-shaped and includes a ninth and tenth disc facets arranged opposite to each other. The ninth disc facet is connected to the first protrusion 1131. The sixth flange 1334 includes a sixth sleeve 13341 and a sixth flange 13342. The sixth sleeve 13341 is fitted onto the end of the first sub-connecting section 1331 near the first sub-support section 113. The sixth flange 13342 is disc-shaped and includes an eleventh and twelfth disc facets arranged opposite to each other. The eleventh disc facet of the sixth flange 13342 corresponds to the tenth disc facet of the fifth flange 1132 and forms the same third mounting hole (not shown). The third fastener achieves a stable connection between the fifth flange 1132 and the sixth flange 1334 through the third mounting hole, and the third fastener is a bolt and nut that fit together. To enhance the strength of the sixth flange 1334, a sixth reinforcing rib 13343 is provided on the outer circumferential surface of the sixth sleeve 13341 of the sixth flange 1334. Meanwhile, both the fifth flange 1132 and the sixth flange 1334 are metal flanges and can be made of materials such as aluminum, iron, and stainless steel.

[0040] The second sub-support section 114 protrudes towards the second sub-connecting section 1332 to form a second protrusion 1141, and the second protrusion 1141 forms a seventh flange 1142. The second sub-connecting section 1332 is sleeved and fixedly connected to one end near the second sub-support section 114 with an eighth flange 1335. The seventh flange 1142 and the eighth flange 1335 are fixedly connected by a fourth fastener (not shown). Specifically, the seventh flange 1142 is disc-shaped and includes a thirteenth and fourteenth disc faces arranged opposite to each other. The thirteenth disc face is connected to the second protrusion 1141. The eighth flange 1335 includes an eighth sleeve 13351 and an eighth flange 13352. The eighth sleeve 13351 is fitted onto one end of the second sub-connecting section 1332 near the second sub-support section 114. The eighth flange 13352 includes a fifteenth and sixteenth disc faces arranged opposite to each other. The fifteenth disc face of the eighth flange 13352 corresponds to the fourteenth disc face of the seventh flange 1142 and forms the same fourth mounting hole (not shown). The fourth fastener achieves a stable connection between the eighth flange 13352 and the seventh flange 1142 through the fourth mounting hole, and the fourth fastener is a bolt and nut that fit together. To enhance the strength of the eighth flange 1335, an eighth reinforcing rib 13353 is provided on the outer circumferential surface of the eighth sleeve 13351 of the eighth flange 1335. Meanwhile, both the seventh flange 1142 and the eighth flange 1335 are metal flanges and can be made of materials such as aluminum, iron, and stainless steel.

[0041] It should be noted that the flange structure of the first sub-connecting section 1331 near the first sub-supporting section 113 in the above embodiment is a different flange structure from the flange structure of the second sub-connecting section 1332 near the second sub-supporting section 114, namely the sixth flange 1334 and the eighth flange 1335, respectively; correspondingly, the flange structure of the first protrusion 1131 near the first connecting portion 131 and the flange structure of the second protrusion 1141 near the first connecting portion 131 are also different flange structures, namely the fifth flange 1132 and the seventh flange 1142, respectively.

[0042] In another embodiment, the flange structure of the first sub-connecting segment 1331 near the first sub-supporting segment 113 and the flange structure of the second sub-connecting segment 1332 near the second sub-supporting segment 114 are the same flange structure, that is, both are the sixth sub-flange; correspondingly, the flange structure of the first protrusion 1131 near the first connecting portion 131 and the flange structure of the second protrusion 1141 near the first connecting portion 131 are also the same flange structure, that is, both are the fifth sub-flange. The fifth sub-flange and the sixth sub-flange are fixedly connected, which can also achieve the purpose of the present invention.

[0043] Traditional substation structures, typically made of all-steel or cement-bonded steel, suffer from several problems: heavy weight, susceptibility to rust or cracking, and generally poor low-temperature performance; difficult transportation and installation; wide corridors, high heights, and large footprints; and susceptibility to faults such as jumper wire deflection and discharge in high winds, significantly impacting equipment reliability; steel structures require surface rust and anti-corrosion treatment every 3-5 years, resulting in high maintenance costs and further affecting equipment reliability.

[0044] To address the aforementioned issues, both the connecting beam 130 and the intermediate beam 120 of this invention are composite post insulators. This design provides the following advantages: it effectively reduces the frame height, width, and land acquisition costs; it also reduces the amount of steel pipe support and foundation work, resulting in lower transportation and installation costs and investment savings; it is more conducive to conserving and utilizing state-owned resources; compared to steel components, composite material products have lower production energy consumption, reducing environmental pollution; simultaneously, composite materials are easy to process and color-adjustable, allowing for environmental harmony and enhancing the environmental friendliness of the line; it achieves the goal of maintenance-free operation throughout its entire life cycle, significantly improving the simplicity of substation frame module operation and maintenance. Furthermore, the use of composite post insulators for the connecting beam 130 provides it with higher bending and compressive strength, further effectively bearing lateral, longitudinal, and vertical loads at the attachment points. Simultaneously, the composite frame, with its excellent external insulation performance, eliminates the safety hazards of pollution flashover and rain flashover, improving the safe operation level of the substation.

[0045] It should be noted that in the above embodiments, both the connecting beam 130 and the intermediate beam 120 are composite post insulators. In another embodiment, the connecting beam 130 may not be a composite post insulator, such as... Figure 2 and Figure 4 As shown, the joint structure 134 connecting the crossbeam 130 is a metal cylindrical structure, that is, both the first sub-connecting head section 1342 and the second sub-connecting head section 1343 are metal cylindrical structures with flanges at both ends. Furthermore, the joint structure 134 can be an integrally molded structure as described in the above embodiment, or it can be a welded structure, which ensures structural stability and strength while also saving costs.

[0046] In addition, such as Figure 1 and Figure 2As shown, in this embodiment, the intermediate crossbeam 120 includes several sub-crossbeams 124 connected end to end. The intermediate crossbeam 120 is provided with a hanging part 125 for suspending wires. The hanging part 125 includes a first hanging plate 1251, a second hanging plate 1252, and a third hanging plate 1253, and each of the first hanging plate 1251, the second hanging plate 1252, and the third hanging plate 1253 is provided with two hanging holes. Of course, in other embodiments of the present invention, the first hanging plate 1251, the second hanging plate 1252, and the third hanging plate 1253 may also be provided with other numbers of hanging holes, all of which are within the protection scope of the present invention and are not limited here.

[0047] The first hanging plate 1251 is fixedly disposed between the first connecting part 131 and the intermediate crossbeam 120, the second hanging part 125 is fixedly disposed between the second connecting part 132 and the intermediate crossbeam 120, and the third hanging plate 1253 is disposed between two adjacent sub-crossbeams 124. Therefore, the number of third hanging plates 1253 increases with the number of sub-crossbeams 124. When there are 2 sub-crossbeams 124, there is 1 third hanging plate 1253; when there are 3 sub-crossbeams 124, there are 2 third hanging plates 1253, and so on. Since the intermediate crossbeam 120 is a composite post insulator, the intermediate crossbeam 120 can directly suspend the conductor using the first hanging plate 1251, the second hanging plate 1252 and the third hanging plate 1253 by utilizing its own insulation performance. This eliminates the tension insulator string in the traditional substation structure, thus eliminating the jumper sag in the traditional substation structure. It can effectively solve the safety hazard of wind-induced tripping, and at the same time, it can reduce the height of the substation structure, save materials, reduce costs, and facilitate installation and maintenance.

[0048] In summary, the present invention forms a triangle with the first connecting part 131 and the first support member 111 forming a triangle with the first end 121 of the intermediate crossbeam 120 as the vertex, and a triangle with the second connecting part 132 and the second support member 112 forming a triangle with the second end 122 of the intermediate crossbeam 120 as the vertex. On the one hand, because the triangular structure is more stable and the connecting crossbeam 130 can bear the lateral, longitudinal, and vertical loads at the suspension points, the strength and stiffness of the substation frame 100 structure provided by the present invention are improved. This effectively controls the actual offset at each suspension point under operating conditions, thus solving the problem in the prior art where the offset of the substation frame 100 at the suspension points is too large, causing it to fail to meet the design standard requirements. On the other hand, the triangle... The structure allows for further miniaturization of the substation frame 100. Specifically, the composite post insulator of the connecting beam 130 can be designed to be smaller than that of the composite post insulator of the intermediate beam 120, thereby reducing the amount of composite materials used and lowering manufacturing costs. Furthermore, compared to the straight beam in the prior art, the combined structure of the intermediate beam 120 and the connecting beam 130 provided by this invention further reduces the impact of its own weight, thereby effectively reducing the vertical load introduced by its own weight. In addition, since the substation frame 100 provided by this invention has increased structural stiffness and reduced offset, it effectively ensures the stress reliability of each connection of the substation frame 100, thereby ensuring the operational reliability of the entire substation frame 100.
