[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] An embodiment of the present application discloses a substation framework 100, such as Figure 1 As shown, it includes a support assembly 110, a beam assembly 120 and a side hanging wire assembly 131. The support assembly 110 includes at least two support columns 111 arranged at intervals, and the at least two support columns 111 include two side support columns 112 located on the two sides, and the two side support columns 112 are respectively a first side support column 1121 and a second side support column 1122; the beam assembly 120 includes a beam 121 erected between every two adjacent support columns 111; the side hanging wire assembly 131 is at least arranged on the first side support column 1121, and is located on the side of the first side support column 1121 away from the beam 121. By arranging a side hanging wire assembly 131 on the side of the first side support column 1121 away from the beam 121, a phase conductor 200 can be further arranged on the substation frame 100, thereby expanding the number of phases of the connected conductors 200, reducing the use of the beam 121 and the support column 111, reducing the use of steel and basic materials, and reducing construction costs.

[0027] Preferably, the first side support column 1121 and the second side support column 1122 are both provided with a side hanging wire assembly 131, so as to further expand the number of phases of the connected conductors 200, reduce the use of beams 121 and support columns 111, reduce the use of steel and basic materials, and reduce construction costs.

[0028] In one embodiment, if Figure 2 As shown, the side wire hanging assembly 131 includes a support cross arm 1311, one end of which is connected to the side support column 112, and the support cross arm 1311 extends in a direction away from the beam 121, and the other end of the support cross arm 1311 is used to hang the wire 200. Specifically, as Figure 1 and Figure 3As shown, first end fittings 180 are respectively connected to both ends of the strut cross arm 1311. The first end fitting 180 includes a first sleeve 181, a first flat plate 182, and a first reinforcing rib 183. Among them, the first sleeve 181 is sleeved and fixed to one end of the strut cross arm 1311. A U-shaped groove matching the end of the first sleeve 181 is provided at one end of the first flat plate 182. The first flat plate 182 is clamped and fixed to the end of the first sleeve 181 through the U-shaped groove. The first flat plate 182 can be fixed to the first sleeve 181 by welding, or the first flat plate 182 can also be integrally formed with the first sleeve 181, and there is no limitation here. The first reinforcing rib 183 is located in the space formed by the surface of the first flat plate 182 and the end face of the first sleeve 181. One side of the first reinforcing rib 183 is fixedly arranged on the surface of the first flat plate 182, and the other side is fixedly arranged on the end face of the first sleeve 181, and the first reinforcing rib 183 can be perpendicular to both the surface of the first flat plate 182 and the end face of the first sleeve 181 at the same time. The first reinforcing rib 183 improves the connection strength between the first flat plate 182 and the first sleeve 181, and avoids the situation of bending or detachment under extreme weather conditions. Specifically, the first reinforcing rib 183 can be fixed to the first flat plate 182 and the first sleeve 181 by welding. In other embodiments, the first reinforcing rib 183 can also be integrally formed with the first flat plate 182, and there is no limitation here. The first end fitting 180 at one end of the strut cross arm 1311 is connected to the side support column 112 through a fastener.

[0029] To enhance the strength of the side wire hanging assembly 131, as Figure 1 and Figure 2 shown, the side wire hanging assembly 131 further includes a stay wire 1312. One end of the stay wire 1312 is connected to the side support column 112, and the other end is connected to the other end of the strut cross arm 1311, improving the stability of the side wire hanging assembly 131. One end of the stay wire 1312 can be connected to the side support column 112, or connected to the connection part of the side support column 112 and the cross beam 121.

[0030] Specifically, as Figure 2 shown, a first right-angle hanging ring group 13121 is connected to one end of the stay wire 1312, and a second right-angle hanging ring group 1123 is connected to the side support column 112. The first right-angle hanging ring group 13121 and the second right-angle hanging ring group 1123 are respectively connected to the first connecting plate 1124, so that one end of the stay wire 1312 is connected to the side support column 112.

[0031] As Figure 4As shown, the other end of the diagonal brace 1312 is connected to the third right-angle hanging ring group 13122, and the first end fitting 180 and the third right-angle hanging ring group 13122 at the other end of the support cross arm 1311 are respectively connected to the second connecting plate 184, so that the other end of the diagonal brace 1312 is connected to the support cross arm 1311.

[0032] Furthermore, if Figure 4 As shown, the support cross arm 1311 and the diagonal brace 1312 are both made of insulating materials, and the conductor 200 can be directly hung on the other end of the support cross arm 1311 through the wire hanging hardware. Since the connection between the support cross arm 1311 and the diagonal brace 1312 is used to hang the conductor, the other end of the support cross arm 1311 and the other end of the diagonal brace 1312 are both provided with a voltage equalizing ring 1313, and the voltage equalizing ring 1313 can evenly distribute the high voltage around to ensure that there is no potential difference between the various parts of the ring, thereby achieving the effect of voltage equalization and preventing abnormal discharge. In addition, since there is an uneven surface at the connection end of the support cross arm 1311 and the diagonal brace 1312, voltage equalizing rings 1313 are also provided on both sides of the second connecting plate 184, and the voltage equalizing rings 1313 are located on both sides of the connection point of the conductor 200, thereby achieving the effect of voltage equalization and preventing abnormal discharge.

[0033] In a specific embodiment, each support column includes a main support column, and a support cross arm is connected to the main support column, and the support cross arm extends in a direction away from the cross beam, one end of the inclined brace is connected to the connection between the side support column and the cross beam, and the other end is connected to the other end of the support cross arm, and the inclined brace, the support cross arm and the main support column form a stable triangular space. The other end of the support cross arm is used to hang the wire.

[0034] In another specific embodiment, Figure 1 and Figure 2 As shown, each support column 111 includes two main support columns 1113, each main support column 1113 is connected to a support cross arm 1311, the support cross arm 1311 extends in a direction away from the cross beam 121, the other ends of the two support cross arms 1311 are connected to each other, one end of the inclined brace 1312 is connected to the connection between the side support column 112 and the cross beam 121, and the other end is connected to the connection end of the two support cross arms 1311, a stable triangular pyramid space is formed between the inclined brace 1312 and the two support cross arms 1311 and the two main support columns 1113, and the connection end of the two support cross arms 1311 is used to hang the wire 200. Preferably, the two support cross arms 1311 are located in the same horizontal plane.

[0035] Furthermore, if Figure 2As shown, the straight line where the axis of the cross beam 121 is located is perpendicular to the plane where the axes of the two main support columns 1113 are located, and an included angle of 5° - 70° is formed between the two main support columns 1113. The two main support columns 1113 and the cross beam 121 are connected by a flange assembly 114. Among the two side support columns 112 on both sides, at least one side support column 112 further includes an inclined support column 1114, and the inclined support column 1114 is connected to the flange assembly 114. The inclined support column 1114 is located outside the plane where the two main support columns 1113 are located to limit the offset of the substation framework 100 in the extending direction of the cross beam 121. In this embodiment, the second side support column 1122 includes an inclined support column 1114, and the inclined support column 1114 is connected to the flange assembly 114. It should be noted that the inclined support column 1114 is arranged on the side away from the cross beam assembly 120, and the inclined support column 1114 is located between the two column cross arms 1311. In other embodiments, the first side support column may also include an inclined support column, which is not specifically limited herein.

[0036] In other embodiments, the side wire hanging assembly further includes a first strain insulator, and the first strain insulator is connected to the other end of the column cross arm. The wire is hung on the side wire hanging assembly through the first strain insulator. At this time, both the column cross arm and the stay wire can be made of metal materials to save costs.

[0037] In one embodiment, as Figure 1 shown, the cross beam 121 is made of a composite insulating material, and the position on the cross beam 121 between the two support columns 111 can be directly used as a wire hanging point. In traditional substation frameworks, since the cross beam is made of metal material, a combination of strain insulator strings, suspension insulator strings or jumpers is required to hang the wire. In one embodiment, the cross beam 121 is made of a composite insulating material, which has excellent electrical insulation performance and can directly hang the wire 200 without using structures such as suspension insulators, reducing the material consumption of structures such as suspension insulators; moreover, since the strain insulator strings, suspension insulator strings and jumpers are saved, the problem of wind-induced discharge that may exist in the substation framework 100 can also be eliminated; the substation framework 100 made of composite insulating material is light in weight, not easy to rust and crack, has high transportation and installation efficiency, and can achieve maintenance-free throughout the life cycle, reducing the operation and maintenance costs of the original porcelain insulator strings. Of course, in other embodiments, the cross beam can also be made of metal material, and a combination of strain insulator strings, suspension insulator strings or jumpers is used to hang the wire.

[0038] In one embodiment, as Figure 5As shown, the crossbeam 121 includes at least two crossbeam segments 1211, such as two, three or more. Two adjacent crossbeam segments 1211 are connected by a flange. The substation framework 100 includes a first wire hanging plate 1212, which is arranged at the flange between two adjacent crossbeam segments 1211. The first wire hanging plate 1212 is provided with a number of wire hanging holes for connecting wire hanging fittings (not shown in the figure) and then hanging the conductor 200. Specifically, the crossbeam 121 includes two crossbeam segments 1211. The proximal ends of the two crossbeam segments 1211 are respectively connected to a first flange 1213. The first wire hanging plate 1212 is clamped between the two first flanges 1213 to hang the conductor 200. Of course, in other embodiments, the crossbeam can also be a complete long crossbeam, with a hoop sleeved on the crossbeam and a wire hanging plate arranged on the hoop to hang the conductor. Voltage equalizing rings 1313 are also arranged on both sides of the first flange 1213. The voltage equalizing rings 1313 can evenly distribute the high voltage around, ensuring that there is no potential difference between various parts of the ring, so as to achieve the effect of voltage equalization and prevent abnormal discharge.

[0039] In one embodiment, as Figure 1 and Figure 2 shown, the crossbeam 121 gradually rises upward along the direction away from the two side support columns 111 to form an arched crossbeam 121, so that the substation framework 100 can use its own arched structure to offset the vertical sag and reduce potential safety hazards. Specifically, a flange assembly 114 is provided between the support column 111 and the crossbeam 121. The end of the support column 111 and the end of the crossbeam 121 are respectively connected to the flange assembly 114. The flange assembly 114 includes a cylinder 1141. The axis of the cylinder 1141 is inclined upward and forms an acute angle with the horizontal plane, thus ensuring that the cylinder 1141 can have a tendency of upward pre-arching after installation. When the flange assembly 114 is connected to the crossbeam 121, a linked pre-arching angle can be generated, so that the crossbeam 121 can gradually rise upward along the direction away from the two side support columns 111 to form an arched crossbeam 121.

[0040] Furthermore, as Figure 1As shown, at least one support column 111 includes a first support portion 1111 and a second support portion 1112 that are connected to each other. The first support portion 1111 is located between the cross beam 121 and the second support portion 1112, and the first support portion 1111 is made of a composite insulating material, while the second support portion 1112 is made of a metal material. The connection between the first support portion 1111 and the cross beam assembly 120 can directly serve as a wire hanging point. Of course, in other embodiments, wire hanging points can be provided on both the first support portion 1111 and the second support portion 1112, and no specific limitation is made here. Since the first support portion 1111 connected to the cross beam 121 is made of a composite insulating material and has excellent electrical insulation performance, the electrical safety distance between the wire 200 and the support column 111 can be reduced, thereby effectively reducing the width of the substation framework 100 and the land acquisition cost. At the same time, since the second support portion 1112 is made of a metal material, the cost can be reduced. In addition, the support column 111 with the above composite structure is light in weight, not easy to rust and crack, thus solving the problem of difficult transportation, installation and maintenance, and reducing the transportation, installation and maintenance costs.

[0041] In order to further reduce the width of the substation framework 100, all support columns 111 include a first support portion 1111 and a second support portion 1112. The first support portion 1111 is made of a composite insulating material, giving full play to its electrical insulation performance and maximizing the reduction of the electrical safety distance between the wire 200 and the support column 111, thereby reducing the width of the substation framework and the land acquisition cost.

[0042] It should be noted that the cross beam 121 and the first support portion 1111 can adopt a post insulator structure. The post insulator includes an insulator located inside and a rubber umbrella skirt covering the outside of the insulator. Specifically, the insulator can be an insulating tube or an insulating core rod. The insulating tube can be a glass fiber tube or an aramid fiber impregnated epoxy resin wound and cured glass steel pipe or a hollow pultruded tube formed by pultrusion; the insulating core rod can be a solid core rod formed by winding and curing glass fiber or aramid fiber impregnated epoxy resin or a pultruded core rod formed by pultrusion. The rubber umbrella skirt can be made of high-temperature vulcanized silicone rubber or other forms of rubber materials. In other embodiments, the cross beam 121 and the first support portion 1111 can also be other composite insulating materials, and no limitation is made here.

[0043] In order to ensure the electrical insulation distance between the wire 200 hung on the wire hanging point at the connection between the cross beam 121 and the first support portion 1111 and the second support portion 1112, such as Figure 1As shown, the substation framework 100 further includes a first support insulator 141. One end of the first support insulator 141 is connected to the support column 111, and the other end is a free end. The free end of the first support insulator 141 is used to support the wire 200 hung at the wire hanging point at the connection of the first support portion 1111 and the crossbeam 121. Preferably, the first support insulator 141 is horizontally arranged or the free end of the first support insulator 141 is higher than the first end of the first support insulator 141.

[0044] Specifically, as Figure 1 and Figure 3 shown, the end of the first support insulator 141 connected to the support column 112 is provided with a second end fitting 190. The second end fitting 190 includes a second sleeve 191 and a second flat plate 192. Among them, the second sleeve 191 is sleeved and fixed at the end of the first support insulator 141. One end of the second flat plate 192 is provided with a U-shaped groove matching the end of the second sleeve 191. The second flat plate 192 is clamped and fixed at the end of the second sleeve 191 through the U-shaped groove. The second flat plate 192 can be fixed to the second sleeve 191 by welding, or the second flat plate 192 can also be integrally formed with the second sleeve 191, and there is no limitation here. The second end fitting 190 at the end of the first support insulator 141 connected to the support column 112 is connected to the support column 112 through a fastener.

[0045] Furthermore, as Figure 3 shown, since the second support portion 1112 made of metal material has higher strength and bearing capacity than the first support portion 1111 made of composite insulating material, the first support insulator 141 can be connected to the connection of the first support portion 1111 and the second support portion 1112. A third connecting plate 193 is provided at the connection of the first support portion 1111 and the second support portion 1112. The second end fitting 190 is connected to the third connecting plate 193 through a fastener. Thus, both the height and strength of the second support portion 1112 can be fully utilized, and it is convenient for the first support insulator 141 to be connected to the support column 111.

[0046] As Figure 1As shown, the substation framework 100 further includes a second strain insulator 151. One end of the second strain insulator 151 is arranged on the support column 111, and the other end is a free end. The free end of the second strain insulator 151 serves as a wire hanging point. In one embodiment, since the first support portion 1111 is made of composite insulating material and the second support portion 1112 is made of metal material, the metal second support portion 1112 has higher strength and bearing capacity compared with the composite insulating first support portion 1111. The second strain insulator 151 can be connected to the connection portion between the first support portion 1111 and the second support portion 1112, so that the height and strength of the second support portion 1112 can be fully utilized, and it is also convenient for the second strain insulator 151 to be connected to the support column 111. Preferably, the second strain insulator 151 is horizontally connected to the support column 111.

[0047] Specifically, as Figure 3 shown, one end of the second strain insulator 151 is connected with a fourth right-angle hanging ring group 1511. A fourth connecting plate 1512 is provided at the connection portion between the first support portion 1111 and the second support portion 1112, and the fourth right-angle hanging ring group 1511 is connected to the fourth connecting plate 1512.

[0048] In other embodiments, the second strain insulator can be arranged on the second support portion or the first support portion.

[0049] Of course, if the length of the first support portion 1111 is relatively long, a wire hanging point can also be directly arranged on the first support portion 1111, as long as the distance between adjacent wire hanging points is greater than a first predetermined value, that is, the electrical insulation distance is satisfied; the distance between the wire hanging point and the second support portion 1112 also needs to satisfy the electrical insulation distance.

[0050] In yet another embodiment, as Figure 7 shown, the substation framework 100 further includes a second crossbeam 160. The second crossbeam 160 is erected between two adjacent support columns 111, and the second crossbeam 160 is located below the crossbeam 121. The second crossbeam 160 is made of metal material. The substation framework 100 further includes a third strain insulator 152. One end of the third strain insulator 152 is connected to the second crossbeam 160, and the other end is a free end. The free end of the third strain insulator 152 serves as a wire hanging point. Thus, without changing the length of the crossbeam 121, one more phase of conductor 200 can be arranged between two adjacent support columns 111, and further, the number of phases of the connected conductors 200 can be expanded, the use of the crossbeam 121 and the support columns 111 can be reduced, the consumption of steel and foundation materials can be reduced, and the construction cost can be reduced; and the space can be fully utilized, the lateral space of the substation framework 100 can be compressed, and the purpose of reducing the occupied area of the substation land can be achieved. Preferably, the third strain insulator 152 is horizontally connected to the support column 111.

[0051] In one embodiment, as Figure 7 andFigure 8 As shown, at both ends of the second crossbeam 160, a second flange 162 is respectively connected. A fixing plate 163 is arranged on the support column 111, and the second flange 162 is fixed to the fixing plate 163 through fasteners. In this embodiment, the second crossbeam 160 includes at least two sub-crossbeams 161, such as two, three or more. Adjacent two sub-crossbeams 161 are connected by flanges. The power transformation framework 100 includes a second wire hanging plate 164. The second wire hanging plate 164 is arranged at the flange between adjacent two sub-crossbeams 161, and a reserved hole is opened on the second wire hanging plate 164. One end of the third strain insulator 152 is connected with a fifth right-angle hanging ring group 1521, and the fifth right-angle hanging ring group 1521 is connected to the reserved hole at the second wire hanging plate 164. In other embodiments, the second crossbeam may also only include one sub-crossbeam. Both ends of the sub-crossbeam are respectively connected to adjacent two support columns, and a hoop is arranged at the middle position of the sub-crossbeam, and a wire hanging plate formed integrally is arranged on the hoop.

[0052] In one embodiment, as Figure 1 shown, the second side support column 1122 is made of metal material. A lightning rod (not shown in the figure) is arranged at the top of the second side support column 1122. Thus, the lightning rod realizes grounding through the second side support column 1122, and the lightning rod can be supported by the support column 111 made of metal material. Compared with independently arranging the lightning rod on the ground, steel can be saved and the cost can be reduced.

[0053] Furthermore, as Figure 1 and Figure 2 shown, one end of the fourth strain insulator 153 is arranged on the second side support column 1122, and the other end is a free end. The free end of the fourth strain insulator 153 can be used as a wire hanging point. Specifically, the fourth strain insulator 153 can be connected to the connection position between the second side support column 1122 and the crossbeam 121, or the fourth strain insulator 153 can be directly connected to the side support column 112. Preferably, the fourth strain insulator 153 is horizontally connected to the side support column 112.

[0054] Specifically, as Figure 2 shown, one end of the fourth strain insulator 153 is connected with a sixth right-angle hanging ring group 1531, and the sixth right-angle hanging ring group 1531 is connected to the flange assembly 114.

[0055] In another embodiment, one of the middle support columns located between two side support columns is made of metal material. A lightning rod is arranged at the top of the middle support column made of metal material. Thus, the lightning rod is directly grounded through the middle support column, and the lightning rod can be supported by the middle support column made of metal material. Compared with independently arranging the lightning rod on the ground, steel can be saved and the cost can be reduced.

[0056] Specifically, since one of the intermediate support columns is made of metal material and a lightning rod is provided at the top, only one wire hanging point can be provided on this intermediate support column, while the two side support columns on both sides can both include a first support part made of composite insulating material, so that three wire hanging points can be provided on both side support columns respectively.

[0057] In another embodiment, all support columns include a first support part and a second support part connected to each other. The first support part is located between the cross beam and the second support part, the first support part is made of composite insulating material, and the second support part is made of metal material. The lightning rod can also be provided on the cross beam assembly or at the top of any support column, and the lightning rod is connected to the second support part through a jumper wire to achieve grounding.

[0058] When the lightning rod is provided on the substation framework 100 and grounded, the substation framework 100 can also include a second support insulator (not shown in the figure). The second support insulator is provided on the cross beam assembly 120, and one end of the second support insulator away from the cross beam assembly 120 is used to set a ground wire, and the ground wire is connected to the lightning rod to achieve grounding.

[0059] It should be noted that when all support columns include a first support part and a second support part connected to each other, the first support part is located between the cross beam and the second support part, the first support part is made of composite insulating material, and the second support part is made of metal material, the substation framework can also include a third support insulator. The third support insulator is provided on the cross beam assembly, and one end of the third support insulator away from the cross beam assembly is used to set a ground wire. The ground wire is directly grounded through a grounding downlead or connected to the second support part through a grounding downlead for grounding.

[0060] In a traditional substation framework, the conductors are arranged horizontally in sequence, resulting in a relatively large horizontal land occupation. In one embodiment, such as Figure 1 and Figure 6As shown in the figure, the single-layer power transformation framework 100 can achieve double-layer wiring, that is, hanging points can be set on both the cross beam 121 and the support column 111. The hanging points set on the cross beam 121 and at the connection between the cross beam 121 and the support column 111 are located in the upper layer, and the hanging points set on the support column 111 are located in the lower layer. In the gas-insulated substation, there is also ground equipment 17. Each phase of the wire 200 corresponds to a set of ground equipment 17, and the ground equipment 17 is arranged below the power transformation framework 100 or on the ground around the power transformation framework 100. The ground equipment 17 includes a gas-insulated transmission pipe 170. The gas-insulated transmission pipe 170 is arranged below the power transformation framework 100 and corresponds one-to-one with the hanging points to receive the wire 200 hung on the corresponding hanging point. Specifically, the hanging points of the three-phase wires 200 in the same circuit of the ground equipment are arranged in a triangular layout, and at the same time, the gas-insulated transmission pipes 170 are arranged in a triangle, so that the wire 200 can be directly led down from the power transformation framework 100 and connected to the ground equipment 17 below or around, thereby making full use of the space, compressing the lateral space of the power transformation framework 100, and achieving the purpose of reducing the occupied area of the substation land.

[0061] As Figure 1 and Figure 6 shown in the figure, along the plane where the axis of the cross beam assembly 120 and the axis of the support assembly 110 are located, the two sides of the power transformation framework 100 are divided into a first side 101 and a second side 102.

Specifically, the wire 200 leads to the power transformation framework 100 from the first side 101, or the wire 200 is led out from the power transformation framework 100 to the first side 101.
