Description

Technical Field

[0001] The present invention relates to the technical field of power transmission and transformation, and particularly to a substation framework. Background Art

[0002] As one of the main equipment in a substation, the substation framework is used for hanging conductors, supporting conductors or switchgear and other electrical equipment.

[0003] The cross beam in the existing substation framework is usually a spliced straight cross beam. When the hanging point load is large, the size requirement of the straight cross beam is designed to be large. The above setting not only causes the product to be heavier, further increasing the bending moment load at the hanging point, but also when the operating condition is too large, the above setting is prone to excessive hanging point offset, not meeting the design standard requirements of the substation framework, and at the same time, it will also cause the bolts at the flange connection to be overstressed and fail. In addition, the larger specification of the straight cross beam also increases the product cost and limits the full promotion of the substation framework.

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

[0005] To achieve the above object, the present invention provides a substation framework, including: a support assembly including a first support member and a second support member spaced apart along a first direction; an intermediate cross beam disposed between the first support member and the second support member, the intermediate cross beam including a first end and a second end opposite to each other along the first direction; a connecting cross beam 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 space between the first connecting portion and the first support member forms a triangular pyramid with the first end as the vertex, and the space between the second connecting portion and the second support member forms a triangular pyramid with the second end as the vertex.

[0006] As a further improvement of the present invention, the first connecting portion and the second connecting portion are symmetrically disposed at both ends of the intermediate cross beam. The first connecting portion and the second connecting portion each include a diagonal bracing connection assembly and a diagonal tension member disposed above the diagonal bracing connection assembly. In the direction from the support assembly to the intermediate cross beam, the diagonal bracing connection assembly is inclined upward, and the diagonal tension member is inclined downward.

[0008] As a further improvement of the present invention, the joint structure protrudes to form a fixing part, and the fixing part is formed with a fixing hole; one end of the stay cable connector close to the middle cross beam forms a clamping part, and the clamping part is formed with a mounting hole; the substation framework further includes a positioning member for fixing the fixing part and the clamping part. When the clamping part clamps the fixing part, the mounting hole cooperates with the fixing hole, and the positioning member passes through the mounting hole and the fixing hole and is fixed.

[0009] As a further improvement of the present invention, first flanges are sleeved and fixed at both ends of the middle cross beam, and second flanges are formed at both ends of the joint structure close to the middle cross beam. The first flange and the second flange are fixedly connected by a first fastener.

[0010] As a further improvement of the present invention, the connecting body includes a first sub-connecting section and a second sub-connecting section. In the direction from the support assembly to the middle cross beam, the first sub-connecting section and the second sub-connecting section gradually approach each other. Third flanges are sleeved and fixed at the ends of the first sub-connecting section and the second sub-connecting section close to the joint structure; the joint structure includes a first sub-joint section and a second sub-joint section. In the direction from the support assembly to the middle cross beam, the first sub-joint section and the second sub-joint section gradually approach each other. The first sub-joint section connects the first sub-connecting section, and the second sub-joint section connects the second sub-connecting section. Fourth flanges are formed at the ends of the first sub-joint section and the second sub-joint section close to the connecting body; the third flange and the fourth flange are fixedly connected by a second fastener.

[0011] As a further improvement of the present invention, the first support member and the second support member are symmetrically arranged. The first support member and the second support member both include a first sub-support section, a second sub-support section, and a third sub-support section fixed to the upper ends of the first sub-support section and the second sub-support section. In the direction from bottom to top, the first sub-support section and the second sub-support section gradually approach each other; the first sub-connecting section is fixedly connected to the first sub-support section, the second sub-connecting section is fixedly connected to the second sub-support section, and one end of the stay cable connector far from the middle cross beam is fixedly connected to the third sub-support section.

[0012] As a further improvement of the present invention, a first connecting plate is formed at the upper ends of the first sub-support section and the second sub-support section, and a second connecting plate is formed at the lower end of the third sub-support section. The first connecting plate and the second connecting plate are snap-fitted and fixedly connected.

[0013] As a further improvement of the present invention, a first protruding portion protrudes from the first sub-support section towards the first sub-connecting section, and a fifth flange is formed on the first protruding portion. A sixth flange is sleeved and fixed at one end of the first sub-connecting section close to the first sub-support section. The fifth flange and the sixth flange are fixedly connected by a third fastener; a second protruding portion protrudes from the second sub-support section towards the second sub-connecting section, and a seventh flange is formed on the second protruding portion. An eighth flange is sleeved and fixed at one end of the second sub-connecting section close to the second sub-support section. The seventh flange and the eighth flange are fixedly connected by a fourth fastener.

[0014] As a further improvement of the present invention, both the connecting cross beam and the intermediate cross beam are composite post insulators.

[0015] The beneficial effects of the present invention are as follows: Different from the prior art, the triangular pyramid spaces formed between the first connecting portion and the first support member and between the second connecting portion and the second support member of the present invention, on the one hand, due to the more stable structure of the triangular pyramid space and the connecting cross beam can bear the transverse, longitudinal, and vertical loads at the hanging point, the strength and stiffness of the substation frame structure provided by the present invention are improved. When the vertical load is too large, the substation frame of the present invention can effectively control the vertical offset of the hanging point at the connection between the connecting cross beam and the intermediate cross beam, and thus can effectively eliminate the problem of excessive vertical offset of the traditional substation frame. On the other hand, the stable triangular pyramid space structure enables the specification of the connecting cross arm to be further miniaturized, reduces the manufacturing cost, reduces the influence of its own weight, and thus effectively reduces the vertical load introduced by the self-weight, so as to effectively control the actual offset at each hanging point under the operating conditions; In addition, due to the improved structural stiffness and reduced offset of the substation frame provided by the present invention, the force reliability of each connection of the substation frame is effectively guaranteed to ensure the operation reliability of the entire substation frame.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 7 , the present invention provides a substation framework 100, including a support assembly 110, an intermediate cross - beam 120 and a connecting cross - beam 130.

[0027] Among them, the support assembly 110 includes a first support member 111 and a second support member 112 which are arranged at intervals in the first direction; the intermediate cross beam 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 which are opposite to each other in the first direction; the connecting cross beam 130 includes a first connecting portion 131 and a second connecting portion 132, the first connecting portion 131 connects the first end 121 and the first support member 111, and the second connecting portion 132 connects the second end 122 and the second support member 112. Moreover, the space between the first connecting portion 131 and the first support member 111 forms a triangular pyramid with the first end 121 as the vertex, and the space between the second connecting portion 132 and the second support member 112 forms a triangular pyramid with the second end 122 as the vertex.

[0028] Thus, through the triangular pyramid space formed between the first connecting portion 131 and the first support member 111, and the triangular pyramid space formed between the second connecting portion 132 and the second support member 112, on the one hand, due to the more stable structure of the triangular pyramid space and the fact that the connecting cross beam 130 can bear the lateral, longitudinal, and vertical loads at the hanging points, the strength and stiffness of the substation framework 100 provided by the present invention are improved. When the vertical load is too large, the substation framework 100 of the present invention can effectively control the vertical offset of the hanging point at the connection between the connecting cross beam 130 and the intermediate cross beam 120, and thus can effectively eliminate the problem of excessive vertical offset of the traditional substation framework. On the other hand, the triangular pyramid space structure enables the specification of the connecting cross beam 130 to be further miniaturized, reduces the manufacturing cost, and reduces the influence of the self-weight of the substation framework 100 itself, thereby effectively reducing the vertical load introduced by the self-weight, and thus can effectively control the actual offset under the operating conditions at each hanging point; in addition, due to the improved structural stiffness and reduced offset of the substation framework 100 provided by the present invention, the force reliability at each connection of the substation framework 100 is effectively ensured to guarantee the operating reliability of the entire substation framework 100.

[0029] Furthermore, in this embodiment, the first connecting portion 131 and the second connecting portion 132 are symmetrically arranged at both ends of the middle cross beam 120. Both the first connecting portion 131 and the second connecting portion 132 include a diagonal bracing connecting assembly 136 and a stay cable connecting member 133 disposed above the diagonal bracing connecting assembly 136. In the direction from the support assembly 110 to the middle cross beam 120, the diagonal bracing connecting assembly 136 is inclined upward, and the stay cable connecting member 133 is inclined downward. Therefore, on the one hand, the arrangement of the diagonal bracing connecting assembly 136 raises the vertical height distance between the middle cross beam 120 and the ground. Even if the middle cross beam 120 generates a vertical offset after hanging the conductor, it will not cause the conductor hanging point offset to be too large when the operating condition is too large, resulting in not meeting the design standard requirements. On the other hand, the arrangement of the stay cable connecting member 133 makes the vertical offset at the connecting hanging point between the connecting cross beam 130 and the middle cross beam 120 of the substation framework 100 of the present invention very limited even when the vertical load is too large, thereby effectively eliminating the problem of excessive vertical offset at the hanging point in the traditional substation framework. In addition, the combined arrangement of the diagonal bracing connecting assembly 136 and the stay cable connecting member 133 shares the hanging point load at the middle hanging point of the middle cross beam 120, thereby effectively controlling the comprehensive offset at the middle hanging point of the middle cross beam 120.

[0030] To realize the connection between the diagonal bracing connecting assembly 136 and the middle cross beam 120, the diagonal bracing connecting assembly 136 includes a connecting body 134 and a joint structure 135 connecting the connecting body 134 and the middle cross beam 120, so as to realize the stable connection between the connecting body 134 and the middle cross beam 120 through the joint structure 135. Specifically, in this embodiment, both the joint structure 135 and the connecting body 134, and the joint structure 135 and the middle cross beam 120 are flange connections. The stay cable connecting member 133 is fixedly connected between the support assembly 110 and the end of the joint structure 135 close to the middle cross beam 120. By means of flange connection, not only the stable connection between the joint structure 135 and the connecting body 134, and the joint structure 135 and the middle cross beam 120 is realized, but also the installation and disassembly are very convenient, which is convenient for maintenance and replacement.

[0031] Of course, in other embodiments of the present invention, other connection methods may also be adopted between the joint structure 135 and the connecting body 134, and the joint structure 135 and the middle cross beam 120, such as welding, etc. As long as the purpose of realizing the stable connection between the joint structure 135 and the connecting body 134, and the joint structure 135 and the middle cross beam 120 is achieved, the purpose of the present invention can be realized.

[0032] Such as Figure 1 and Figure 4As shown, in order to achieve a stable connection between the intermediate cross beam 120 and the joint structure 135, in this embodiment, first flanges 123 are sleeved and fixed at both ends of the intermediate cross beam 120, and second flanges 1352 are formed at one end of the joint structure 135 close to the intermediate cross beam 120. The first flange 123 and the second flange 1352 are fixedly connected by a first fastener (not shown).

[0033] Specifically, in one embodiment, the first flange 123 includes a first socket cylinder 1231 and a first flange plate 1232. The first socket cylinder 1231 is sleeved on the end of the intermediate cross beam 120. Further, as Figure 5 shown, the first flange plate 1232 includes a first main body portion 12321 in the shape of a disc, a first inclined hanging portion 12322 and a second inclined hanging portion 12323 connected to the lower end of the first main body portion 12321. Hanging holes for hanging wires are provided on the first inclined hanging portion 12322 and the second inclined hanging portion 12323, that is, the first main body portion 12321, the first inclined hanging portion 12322 and the second inclined hanging portion 12323 in this embodiment are integrally formed. Of course, in other embodiments, the first inclined hanging portion 12322 and the second inclined hanging portion 12323 for hanging wires may also be provided on the second flange 1352, or the first flange plate 1232 is directly set as a disc shape, and the second flange 1352 is also directly set as a disc shape. A hanging wire plate for hanging wires is additionally provided between the first flange plate 1232 and the second flange 1352, and the hanging wire plate is fixed between the first flange plate 1232 and the second flange 1352, and the purpose of the present invention can also be achieved. And, the first main body portion 12321 includes a first disc surface and a second disc surface arranged opposite to each other.

[0034] In this embodiment, the second flange 1352 is in the shape of a disc and includes a third disc surface and a fourth disc surface arranged opposite to each other. The third disc surface is closely fixed to the first disc surface of the first main body portion 12321, and the fourth disc surface is connected to one end of the joint structure 135 close to the intermediate cross beam 120. The first disc surface of the first flange plate 1232 and the third disc surface of the second flange 1352 are correspondingly provided with the same first positioning holes (not shown). The first fastener realizes the fastening installation of the first flange plate 1232 and the second flange 1352 through the first positioning holes, and the first fastener is a bolt and a nut that cooperate with each other. In addition, in this embodiment, a plurality of first reinforcing ribs 1233 are further provided on the outer peripheral surface of the first socket cylinder 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 1352 are metal flanges and can be made of materials such as aluminum, iron, and stainless steel.

[0035] To fix the stay cable connector 133 to the joint structure 135, the joint structure 135 protrudes to form a fixing portion 1351, and the fixing portion 1351 is connected to the fourth disk surface of the second flange 1352. The fixing portion 1351 is formed with a fixing hole (not shown); one end of the stay cable connector 133 close to the middle cross beam 120 is formed with a clamping portion 1331, and the clamping portion 1331 is formed with a mounting hole (not labeled); the substation frame 100 further includes a positioning member (not shown) for fixing the fixing portion 1351 and the clamping portion 1331. When the clamping portion 1331 clamps the fixing portion 1351, the mounting hole cooperates with the fixing hole, and the positioning member passes through the mounting hole and the fixing hole and is fixed. Specifically, in this embodiment, the positioning member is a bolt and a nut that cooperate with each other. Through the above fixing method, the installation and disassembly between the stay cable connector 133 and the joint structure 135 are very convenient.

[0036] Of course, in other embodiments of the present invention, the stay cable connector 133 and the joint structure 135 can also be fixedly connected in other ways, such as welding or snap connection, etc. As long as the effect of fixing one end of the stay cable connector 133 to the joint structure 135 is achieved, the purpose of the present invention can be realized. And, the above positioning member can also be of other types, as long as the effect of fixing the fixing portion 1351 and the clamping portion 1331 is achieved, the purpose of the present invention can be realized.

[0037] In addition, as Figure 1 、 Figure 4 and Figure 6 shown, in order to achieve a stable connection between the connection body 134 and the joint structure 135, in an embodiment, the connection body 134 includes a first sub-connection section 1341 and a second sub-connection section 1342. In the direction from the support assembly 110 to the middle cross beam 120, the first sub-connection section 1341 and the second sub-connection section 1342 gradually approach each other. One end of the first sub-connection section 1341 and the second sub-connection section 1342 close to the joint structure 135 is sleeved and fixed with a third flange 1343. Correspondingly, the joint structure 135 includes a first sub-connection head section 1353 and a second sub-connection head section 1354. In the direction from the support assembly 110 to the middle cross beam 120, the first sub-connection head section 1353 and the second sub-connection head section 1354 gradually approach each other and are simultaneously connected to the fourth disk surface of the second flange 1352. The first sub-connection head section 1353 is connected to the first sub-connection section 1341, the second sub-connection head section 1354 is connected to the second sub-connection section 1342, and one end of the first sub-connection head section 1353 and the second sub-connection head section 1354 close to the connection body 134 is formed with a fourth flange 1355. And, the third flange 1343 and the fourth flange 1355 are fixedly installed through a second fastener (not shown).

[0038] Specifically, the third flange 1343 includes a third socket cylinder 13431 and a third flange plate 13432 in the shape of a disc. The third socket cylinder 13431 is sleeved on the ends of the first sub-connection segment 1341 and the second sub-connection segment 1342 close to the joint structure 135. Moreover, the third flange plate 13432 includes a fifth disc surface and a sixth disc surface disposed opposite to each other; the fourth flange 1355 is in the shape of a disc and includes a seventh disc surface and an eighth disc surface disposed opposite to each other. The fifth disc surface of the third flange plate 13432 is closely fixed to the seventh disc surface of the fourth flange 1355. The fifth disc surface of the third flange plate 13432 and the seventh disc surface of the fourth flange 1355 are correspondingly provided with the same second positioning holes (not shown). The second fasteners respectively achieve the fastening installation of the first sub-connection segment 1341 and the first sub-connection head segment 1353, and the second sub-connection segment 1342 and the second sub-connection head segment 1354 through the second positioning holes. Moreover, the second fasteners are also bolts and nuts that cooperate with each other.

[0039] To strengthen the strength of the third flange 1343 and the fourth flange 1355, a plurality of third reinforcing ribs 13433 are provided on the outer peripheral surface of the third socket cylinder 13431, and a plurality of fourth reinforcing ribs 1356 are arranged circumferentially on the eighth disc surface of the fourth flange 1355 to increase the strength of the third flange 1343 and the fourth flange 1355. Of course, the third reinforcing ribs 13433 and the fourth reinforcing ribs 1356 can also be selectively provided as needed. For example, the third reinforcing ribs 13433 are provided on both of the two third flanges 1343, and the fourth reinforcing ribs 1356 are provided on one of the two fourth flanges 1355, which are all within the protection scope of the present invention. At the same time, both the third flange 1343 and the fourth flange 1355 are metal flanges and can be made of materials such as aluminum, iron, and stainless steel.

[0040] It should be noted that the flange structures at the ends of the first sub-connection segment 1341 close to the joint structure 135 and the second sub-connection segment 1342 close to the joint structure 135 in the above embodiments are the same flange structure, that is, both are the third flange 1343; correspondingly, the flange structures at the ends of the first sub-connection head segment 1353 close to the connection main body 134 and the second sub-connection head segment 1354 close to the connection main body 134 are also the same flange structure, that is, both are the fourth flange 1355.

[0041] In another embodiment, the flange structures of the first sub-connection segment 1341 near one end of the joint structure 135 and the flange structures of the second sub-connection segment 1342 near one end of the joint structure 135 can also be different flange structures, for example, the first sub-flange and the second sub-flange respectively; correspondingly, the flange structures of the first sub-connection head segment 1353 near one end of the connection body 134 and the flange structures of the second sub-connection head segment 1354 near one end of the connection body 134 can also be different flange structures, for example, the third sub-flange and the fourth sub-flange respectively. The first sub-flange is fixedly connected to the third sub-flange, and the second sub-flange is fixedly connected to the fourth sub-flange, and the object of the present invention can also be achieved.

[0042] In addition, as Figure 1 , Figure 2 and Figure 3 shown, the first support member 111 and the second support member 112 are symmetrically arranged. The first support member 111 and the second support member 112 both include a first sub-support segment 113, a second sub-support segment 114, and a third sub-support segment 115 fixed to the upper ends of the first sub-support segment 113 and the second sub-support segment 114. In the upward direction, the first sub-support segment 113 and the second sub-support segment 114 gradually approach each other; the first sub-connection segment 1341 is fixedly connected to the first sub-support segment 113, the second sub-connection segment 1342 is fixedly connected to the second sub-support segment 114, and one end of the stay cable connector 133 away from the middle cross beam 120 is fixedly connected to the third sub-support segment 115.

[0043] Specifically, the stay cable connector 133 is fixedly connected to the top of the third sub-support segment 115, and the connection method between the two is fastening through the cooperation of bolts and nuts. Of course, in other embodiments of the present invention, other fixing methods can also be used, such as welding, snap connection, etc. As long as the effect of fixedly connecting the stay cable connector 133 to the third sub-support segment 115 is achieved, the object of the present invention can be realized.

[0044] Through the above settings, a stable support structure is formed between the first sub-support segment 113 and the second sub-support segment 114, so that the support assembly 110 can provide a stable support function. Of course, in other embodiments of the present invention, the first sub-support segment 113 and the second sub-support segment 114 can also be set to other shapes, such as triangles, etc. As long as the effect of stable support is achieved, the object of the present invention can be realized. In addition, the first sub-support segment 113 and the second sub-support segment 114 can both be a continuous support body or be spliced by multiple support bodies. It should be noted that both the first support member 111 and the second support member 112 are made of iron, and of course, other metal materials can also be used.

[0045] Furthermore, in order to achieve the fixed connection between the third sub-support segment 115 and the first sub-support segment 113 and the second sub-support segment 114, a first connecting plate 116 is formed at the upper ends of the first sub-support segment 113 and the second sub-support segment 114, and a second connecting plate 117 is formed at the lower end of the third sub-support segment 115. The first connecting plate 116 and the second connecting plate 117 are fastened and fixedly connected, or can also be fixedly connected by fasteners.

The third fastener realizes the firm connection between the fifth flange 1132 and the sixth flange 1344 through the third positioning holes, and the third fastener is a bolt and a nut that cooperate with each other. In order to strengthen the strength of the sixth flange 1344, a sixth reinforcing rib 13443 is provided on the outer peripheral surface of the sixth socket cylinder 13441 of the sixth flange 1344. At the same time, both the fifth flange 1132 and the sixth flange 1344 are metal flanges and can be made of materials such as aluminum, iron, and stainless steel.

[0049] The second sub-support segment 114 protrudes towards the second sub-connection segment 1342 to form a second protrusion 1141. A seventh flange 1142 is formed on the second protrusion 1141. An eighth flange 1345 is sleeved and fixed at one end of the second sub-connection segment 1342 close to the second sub-support segment 114. The seventh flange 1142 and the eighth flange 1345 are fixedly connected by a fourth fastener (not shown). Specifically, the seventh flange 1142 is in a disc shape and includes a thirteenth disc surface and a fourteenth disc surface arranged opposite to each other. The thirteenth disc surface is connected to the second protrusion 1141. The eighth flange 1345 includes an eighth socket cylinder 13451 and an eighth flange plate 13452. The eighth socket cylinder 13451 is sleeved on one end of the second sub-connection segment 1342 close to the second sub-support segment 114. The eighth flange plate 13452 includes a fifteenth disc surface and a sixteenth disc surface arranged opposite to each other.

In order to strengthen the strength of the eighth flange 1345, an eighth reinforcing rib 13453 is provided on the outer peripheral surface of the eighth socket cylinder 13451 of the eighth flange 1345. At the same time, both the seventh flange 1142 and the eighth flange 1345 are metal flanges and can be made of materials such as aluminum, iron, and stainless steel.

[0050] It should be noted that the flange structures of the first sub-connection segment 1341 near one end of the first sub-support segment 113 and the second sub-connection segment 1342 near one end of the second sub-support segment 114 in the above embodiments are different flange structures, namely the sixth flange 1344 and the eighth flange 1345 respectively; correspondingly, the flange structures of the first protrusion 1131 near one end of the first connection portion 131 and the second protrusion 1141 near one end of the first connection portion 131 are also different flange structures, namely the fifth flange 1132 and the seventh flange 1142 respectively.

[0051] In another embodiment, the flange structures of the first sub-connection segment 1341 near one end of the first sub-support segment 113 and the second sub-connection segment 1342 near one end of the second sub-support segment 114 are the same flange structure, that is, both are the sixth sub-flange; correspondingly, the flange structures of the first protrusion 1131 near one end of the first connection portion 131 and the second protrusion 1141 near one end of the first connection portion 131 are also the same flange structure, that is, both are the fifth sub-flange, and the fifth sub-flange is fixedly connected to the sixth sub-flange, and the object of the present invention can also be achieved.

[0052] Since there are many problems in the traditional substation framework using all-steel or cement-combined steel structure, such as heavy quality, easy to rust or crack, general low-temperature performance; difficult in transportation, installation and other links; wide corridor, high height, large floor area, and easy to occur faults such as jumper wind deviation discharge under strong wind conditions, which has a greater impact on the operation reliability of equipment; the steel structure needs to be treated for rust and anti-corrosion on the surface every 3-5 years of operation, with high operation and maintenance costs and a greater impact on the operation reliability of equipment, etc.

[0053] To solve the above problems, both the connecting crossbeam 130 and the intermediate crossbeam 120 of the present invention are composite post insulators. Through the above arrangement, the present invention has the following advantages: it can effectively reduce the frame height, reduce the frame width and land acquisition cost, reduce the steel pipe support and foundation engineering quantity, and accordingly reduce the transportation and installation costs, saving investment; it is more conducive to saving and utilizing state-owned resources; compared with steel components, composite material products have low production energy consumption and reduce environmental pollution; at the same time, composite materials are easy to process and the color can be adjusted, which can be coordinated with the environment, enhancing the environmental friendliness of the line; the goal of maintenance-free throughout the life cycle is achieved, greatly improving the simplicity of operation and maintenance of the power station frame module. In addition, since the connecting crossbeam 130 is a composite post insulator, that is, both the diagonal bracing connection assembly 136 and the stay connection 133 are composite post insulators, therefore, the diagonal bracing connection assembly 136 has high bending and compressive strength, and the stay connection 133 has extremely high tensile load. When the vertical load is too large, the stay connection 133 has a small deformation amount, thereby effectively controlling the vertical offset at the hanging point of the intermediate crossbeam 120. At the same time, the composite frame eliminates the safety hazards of pollution flashover and rain flashover with its excellent external insulation performance, improving the safe operation level of the substation.

[0054] It should be noted that both the connecting crossbeam 130 and the intermediate crossbeam 120 in the above embodiment are composite post insulators. In another embodiment, the connecting crossbeam 130 may not be a composite post insulator, such as Figure 2 and Figure 4 shown, the joint structure 135 of the connecting crossbeam 130 is a metal light cylinder structure, that is, both the first sub-connection head section 1353 and the second sub-connection head section 1354 are metal light cylinders with flanges at both ends. At the same time, the joint structure 135 can be an integrally formed structure or a welded structure in the above embodiment, which can save costs while ensuring the structural stability and strength.

[0055] In addition, as Figure 1 and Figure 2 shown, in this embodiment, the intermediate crossbeam 120 includes a plurality of sub-crossbeams 124. The plurality of sub-crossbeams 124 are connected end to end. A wire hanging portion 125 is provided on the intermediate crossbeam 120. The wire hanging portion 125 includes a first wire hanging plate 1251, a second wire hanging plate 1252 and a third wire hanging plate 1253, and two wire hanging holes are respectively provided on the first wire hanging plate 1251, the second wire hanging plate 1252 and the third wire hanging plate 1253. Of course, in other embodiments of the present invention, other numbers of wire hanging holes may also be respectively provided on the first wire hanging plate 1251, the second wire hanging plate 1252 and the third wire hanging plate 1253, which are all within the protection scope of the present invention and are not limited herein.

[0056] Among them, the first wire hanging plate 1251 is fixedly arranged between the first connecting part 131 and the middle cross beam 120, the second wire hanging part 1252 is fixedly arranged between the second connecting part 132 and the middle cross beam 120, and the third wire hanging plate 1253 is arranged between two adjacent sub-cross beams 124. Therefore, the number of the third wire hanging plates 1253 increases with the increase of the number of the sub-cross beams 124. When the number of the sub-cross beams 124 is 2, the number of the third wire hanging plates 1253 is 1; when the number of the sub-cross beams 124 is 3, the number of the third wire hanging plates 1253 is 2, and so on. Since the middle cross beams 120 are all composite post insulators, the middle cross beams 120 directly use the first wire hanging plate 1251, the second wire hanging plate 1252 and the third wire hanging plate 1253 to hang the conductors by using their own insulation performance, canceling the strain insulator strings in the traditional substation framework, that is, eliminating the jumper sag in the traditional substation framework, which can effectively solve the safety hazard of wind-induced deviation and tripping, and at the same time can also reduce the height of the substation structure, save materials, reduce costs and facilitate installation, operation and maintenance.

[0057] In summary, through the triangular pyramid spaces formed between the first connecting part 131 and the first support 111 and between the second connecting part 132 and the second support 112, on the one hand, due to the more stable structure of the triangular pyramid space and the connecting cross beam 130 can bear the transverse, longitudinal and vertical loads at the hanging points, the strength and stiffness of the substation framework 100 provided by the present invention are improved. When the vertical load is too large, the substation framework 100 of the present invention can effectively control the vertical offset of the hanging point at the connection between the connecting cross beam 130 and the middle cross beam 120, and thus can effectively eliminate the problem of excessive vertical offset of the traditional substation framework. On the other hand, the triangular pyramid space structure makes the specifications of the substation framework 100 further miniaturized, that is, the specifications of the composite post insulators of the connecting cross beam 130 can be designed to be smaller than those of the composite post insulators of the middle cross beam 120, thereby reducing the amount of composite materials used, reducing the manufacturing cost, reducing the influence of its own weight, and further effectively reducing the vertical load introduced by the self-weight, so as to effectively control the actual offset at each hanging point under the operating conditions; in addition, due to the improved structural stiffness and reduced offset of the substation framework 100 provided by the present invention, the force reliability of each connection of the substation framework 100 is effectively guaranteed to ensure the operation reliability of the whole substation framework 100.

[0058] The above is only the embodiment of the present invention, and thus does not limit the patent scope of the present invention. Any equivalent structure or equivalent principle transformation made by using the content of the specification and drawings of the present invention, directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
