[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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, the two ends of the pillar cross arm 1311 are respectively connected with the first end hardware 180, and the first end hardware 180 includes a first sleeve 181, a first plate 182 and a first reinforcing rib 183. Among them, the first sleeve 181 is sleeved and fixed on one end of the pillar cross arm 1311, and one end of the first plate 182 is provided with a U-shaped groove matching the end of the first sleeve 181. The first plate 182 is fixed to the end of the first sleeve 181 through the U-shaped groove. The first plate 182 can be fixed to the first sleeve 181 by welding, or the first plate 182 can also be integrally formed with the first sleeve 181, which is not limited here. The first reinforcing rib 183 is located in the space formed by the surface of the first 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 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 the surface of the first 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 plate 182 and the first sleeve 181 to prevent them from bending or detaching under extreme weather conditions. Specifically, the first reinforcing rib 183 can be fixed to the first 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 plate 182, which is not limited here. The first end fitting 180 at one end of the pillar cross arm 1311 is connected to the side support column 112 by fasteners.

[0030] In order to improve the strength of the side hanging wire assembly 131, Figure 1 and Figure 2 As shown, the side wire hanging assembly 131 also includes an inclined brace 1312, one end of the inclined brace 1312 is connected to the side support column 112, and the other end is connected to the other end of the pillar cross arm 1311, thereby improving the stability of the side wire hanging assembly 131. One end of the inclined brace 1312 can be connected to the side support column 112, or connected to the connection between the side support column 112 and the cross beam 121.

[0031] Specifically, Figure 2 As shown, one end of the diagonal brace 1312 is connected to a first right-angle hanging ring group 13121, 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 diagonal brace 1312 is connected to the side support column 112.

[0032] like 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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 angle of 5°-70° is formed between the two main support columns 1113. The two main support columns 1113 are connected to the cross beam 121 through a flange assembly 114. Among the two side support columns 112 located on both sides, at least one side support column 112 also includes an oblique support column 1114, which is connected to the flange assembly 114, and the oblique support column 1114 is located outside the plane where the two main support columns 1113 are located, so as to limit the deviation of the substation frame 100 along the extension direction of the cross beam 121. In this embodiment, the second side support column 1122 includes an oblique support column 1114, which is connected to the flange assembly 114. It should be noted that the oblique support column 1114 is set to the side away from the cross beam assembly 120, and the oblique support column 1114 is located between the two pillar cross arms 1311. In other embodiments, the first side support column may also include an oblique support column, which is not specifically limited herein.

[0037] In other embodiments, the side hanging wire assembly also includes a first tension insulator, which is connected to the other end of the support crossarm, and the conductor is hung on the side hanging wire assembly through the first tension insulator. At this time, the support crossarm and the inclined member can both be made of metal materials to save costs.

[0038] In one embodiment, if Figure 1 As shown, the crossbeam 121 is a composite insulating material, and the position between the two support columns 111 on the crossbeam 121 can be directly used as a hanging point. Since the crossbeam in the traditional substation frame is made of metal material, it is necessary to use a combination of a tension insulator string, a suspension insulator string or a jumper to hang the wire. In one embodiment, the crossbeam 121 is a composite insulating material with excellent electrical insulation performance, and can directly hang the wire 200 without using structures such as suspension insulators, thereby reducing the material consumption of structures such as suspension insulators; and, since the tension insulator string, the suspension insulator string and the jumper are saved, the problem of wind deflection discharge that may exist in the substation frame 100 can also be eliminated; the substation frame 100 using the 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 string. Of course, in other embodiments, the crossbeam can also be made of metal material, and a combination of a tension insulator string, a suspension insulator string or a jumper is used to hang the wire.

[0039] In one embodiment, if Figure 5As shown, the crossbeam 121 includes at least two crossbeam sections 1211, for example, two, three or more, and two adjacent crossbeam sections 1211 are connected by flanges. The substation frame 100 includes a first hanging plate 1212, which is arranged at the flange between two adjacent crossbeam sections 1211. The first hanging plate 1212 has a plurality of hanging holes, which are used to connect hanging fittings (not shown in the figure) and then hang the wire 200. Specifically, the crossbeam 121 includes two crossbeam sections 1211, and the adjacent ends of the two crossbeam sections 1211 are respectively connected to a first flange 1213, and the first hanging plate 1212 is sandwiched between the two first flanges 1213 to hang the wire 200. Of course, in other embodiments, the crossbeam can also be a complete long crossbeam, and a clamp is provided on the crossbeam, and a hanging plate is provided on the clamp to hang the wire. Voltage equalizing rings 1313 are also provided on both sides of the first flange 1213. The voltage equalizing rings 1313 can evenly distribute the high voltage around to ensure that there is no potential difference between various parts of the ring, thereby achieving the effect of voltage equalization and preventing abnormal discharge.

[0040] In one embodiment, if Figure 1 and Figure 2 As shown, the cross beam 121 gradually rises upward in a direction away from the support columns 111 on both sides to form an arched cross beam 121, so that the substation frame 100 can use its own arched structure to offset the vertical sag and reduce safety hazards. Specifically, a flange assembly 114 is provided between the support column 111 and the cross beam 121, and the ends of the support column 111 and the ends of the cross beam 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, thereby ensuring that the cylinder 1141 can have a tendency to pre-arch upward after installation. When the flange assembly 114 is connected to the cross beam 121, a linkage pre-arch angle can be generated, so that the cross beam 121 can be gradually lifted upward in a direction away from the support columns 111 on both sides to form an arched cross beam 121.

[0041] Furthermore, if Figure 1As shown, at least one support column 111 includes a first support portion 1111 and a second support portion 1112 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 a composite insulating material, the second support portion 1112 is a metal material, and the connection between the first support portion 1111 and the cross beam assembly 120 can be directly used as a hanging point. Of course, in other embodiments, hanging points can be set on both the first support portion 1111 and the second support portion 1112, and no specific restrictions are made here. Since the first support portion 1111 connected to the cross beam 121 is a composite insulating material, it has excellent electrical insulation performance, so that the electrical safety distance between the conductor 200 and the support column 111 can be reduced, thereby effectively reducing the width of the substation frame 100 and the land acquisition cost. At the same time, the second support portion 1112 is made of metal material, which can achieve the effect of reducing costs. In addition, the support column 111 of the composite structure is light in weight, not easy to rust and crack, which correspondingly solves the problem of difficult transportation, installation and maintenance, and reduces the transportation, installation and maintenance costs.

[0042] In order to further reduce the width of the substation frame 100, all support columns 111 include a first support part 1111 and a second support part 1112. The first support part 1111 is made of composite insulating material to give full play to its electrical insulation performance and minimize the electrical safety distance between the conductor 200 and the support column 111, thereby reducing the width of the substation structure and the land acquisition costs.

[0043] It should be noted that the crossbeam 121 and the first support portion 1111 may adopt a post insulator structure, and the post insulator includes an insulator located inside and a rubber shed wrapped outside the insulator. Specifically, the insulator may be an insulating tube or an insulating core rod. The insulating tube may be a glass fiber reinforced plastic tube formed by winding and curing by glass fiber or aramid fiber impregnated with epoxy resin, or a hollow pultruded tube formed by pultrusion; the insulating core rod may be a solid core rod formed by winding and curing by glass fiber or aramid fiber impregnated with epoxy resin, or a pultruded core rod formed by pultrusion. The rubber shed may be made of high-temperature vulcanized silicone rubber, or other forms of rubber materials. In other embodiments, the crossbeam 121 and the first support portion 1111 may also be other composite insulating materials, which are not limited here.

[0044] In order to ensure the electrical insulation distance between the wire 200 hung at the hanging point connected to the connection between the cross beam 121 and the first support part 1111 and the second support part 1112, as shown in FIG. Figure 1As shown, the transformer substation frame 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, and the free end of the first support insulator 141 is used to support the wire 200 hung at the hanging point at the connection between 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.

[0045] Specifically, Figure 1 and Figure 3 As shown, the end of the first support insulator 141 connected to the support column 112 is provided with a second end fitting 190, and the second end fitting 190 includes a second sleeve 191 and a second plate 192. The second sleeve 191 is sleeved and fixed on the end of the first support insulator 141, and one end of the second plate 192 is provided with a U-shaped groove matching the end of the second sleeve 191. The second plate 192 is fixed to the end of the second sleeve 191 by the U-shaped groove. The second plate 192 can be fixed to the second sleeve 191 by welding, or the second plate 192 can be integrally formed with the second sleeve 191, which is not limited here. The second end fitting 190 at one end of the first support insulator 141 connected to the support column 112 is connected to the support column 112 by a fastener.

[0046] Furthermore, if Figure 3 As shown, since the second support part 1112 of the metal material has higher strength and bearing capacity than the first support part 1111 of the composite insulating material, the first support insulator 141 can be connected to the connection between the first support part 1111 and the second support part 1112, and the connection between the first support part 1111 and the second support part 1112 is provided with a third connecting plate 193, and the second end fitting 190 is connected to the third connecting plate 193 through a fastener. In this way, the height and strength of the second support part 1112 can be fully utilized, and the first support insulator 141 can be conveniently connected to the support column 111.

[0047] like Figure 1As shown, the substation frame 100 further includes a second tension insulator 151, one end of which is arranged on the support column 111, and the other end is a free end, and the free end of the second tension insulator 151 serves as a wire hanging point. In one embodiment, since the first support portion 1111 is a composite insulating material, and the second support portion 1112 is a metal material, the second support portion 1112 of the metal material has higher strength and bearing capacity than the first support portion 1111 of the composite insulating material, the second tension insulator 151 can be connected to the connection between the first support portion 1111 and the second support portion 1112, so as to fully utilize the height and strength of the second support portion 1112, and facilitate the connection of the second tension insulator 151 to the support column 111. Preferably, the second tension insulator 151 is horizontally connected to the support column 111.

[0048] Specifically, Figure 3 As shown, one end of the second tension insulator 151 is connected to a fourth right-angle hanging ring group 1511 , a fourth connecting plate 1512 is provided at the connection 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 .

[0049] In other embodiments, the second tension insulator may be disposed on the second supporting portion or the first supporting portion.

[0050] Of course, if the length of the first support part 1111 is longer, a hanging point can be directly set on the first support part 1111. It only needs that the distance between adjacent hanging points is greater than the first predetermined value to meet the electrical insulation distance; the distance between the hanging point and the second support part 1112 also needs to meet the electrical insulation distance.

[0051] In yet another embodiment, Figure 7 As shown, the substation frame 100 also includes a second crossbeam 160, which 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, and the substation frame 100 also includes a third tension insulator 152, one end of the third tension insulator 152 is connected to the second crossbeam 160, and the other end is a free end, and the free end of the third tension insulator 152 is used as a hanging point. Therefore, when the length of the crossbeam 121 remains unchanged, a phase conductor 200 can be set between two adjacent support columns 111, thereby expanding the number of phases of the connected conductors 200, reducing the use of crossbeams 121 and support columns 111, reducing the amount of steel and basic materials, and reducing construction costs; and can make full use of space, compress the horizontal space of the substation frame 100, and achieve the purpose of reducing the occupied area of ​​the substation land. Preferably, the third tension insulator 152 is horizontally connected to the support column 111.

[0052] In one embodiment, if Figure 7 and Figure 8 As shown, the second crossbeam 160 has two ends connected to a second flange 162, a fixing plate 163 is provided on the support column 111, and the second flange 162 is fixed to the fixing plate 163 by fasteners. In this embodiment, the second crossbeam 160 includes at least two sub-crossbeams 161, for example, two, three or more, and two adjacent sub-crossbeams 161 are connected by flanges. The substation frame 100 includes a second hanging plate 164, which is arranged at the flange between two adjacent sub-crossbeams 161, and the second hanging plate 164 has a reserved hole. One end of the third tension insulator 152 is connected to the 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 hanging plate 164. In other embodiments, the second crossbeam can also include only one sub-crossbeam, and the two ends of the sub-crossbeam are respectively connected to two adjacent support columns, and a clamp is provided in the middle of the sub-crossbeam, and an integrally formed hanging plate is provided on the clamp.

[0053] In one embodiment, if Figure 1 As shown, the second side support column 1122 is made of metal material, and a lightning rod (not shown in the figure) is arranged on the top of the second side support column 1122, so that the lightning rod is grounded 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 setting the lightning rod on the ground, steel can be saved and costs can be reduced.
