[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] An embodiment of the present application discloses a substation frame 100, as shown in FIG1 , comprising a support assembly 110, a crossbeam assembly 120, and a side wire hanging assembly 131. The support assembly 110 comprises at least two support columns 111 arranged at intervals, wherein the at least two support columns 111 include two side support columns 112 located on both sides, the two side support columns 112 being a first side support column 1121 and a second side support column 1122; the crossbeam assembly 120 comprises a crossbeam 121 erected between every two adjacent support columns 111; and the side wire hanging assembly 131 is at least disposed on the first side support column 1121 and is located on the side of the first side support column 1121 facing away from the crossbeam 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 beams 121 and support columns 111, reducing the use of steel and basic materials, and reducing construction costs.

[0034] 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 wires 200, reduce the use of beams 121 and support columns 111, reduce the use of steel and basic materials, and reduce construction costs.

[0035] In one embodiment, as shown in FIG2 , the side wire hanging assembly 131 includes a support crossarm 1311 , one end of which is connected to the side support column 112 and extends away from the crossbeam 121 . The other end of the support crossarm 1311 is used to hang the wire 200 . Specifically, as shown in FIG1 and FIG3 , the two ends of the support crossarm 1311 are respectively connected to a first end fitting 180 . The first end fitting 180 includes a first sleeve 181 , a first plate 182 , and a first reinforcing rib 183 . The first sleeve 181 is sleeved and fixed to one end of the support crossarm 1311 . One end of the first plate 182 has a U-shaped groove that matches the end of the first sleeve 181 . The first plate 182 is fixed to the end of the first sleeve 181 by the U-shaped groove. The first plate 182 can be fixed to the first sleeve 181 by welding, or the first plate 182 can be integrally formed with the first sleeve 181 , without limitation. 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. 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 crossarm 1311 is connected to the side support column 112 by fasteners.

[0036] To enhance the strength of the side wire hanging assembly 131, as shown in Figures 1 and 2, the side wire hanging assembly 131 further includes a diagonal brace 1312. One end of the diagonal brace 1312 is connected to the side support column 112, and the other end is connected to the other end of the support cross arm 1311, thereby enhancing the stability of the side wire hanging assembly 131. One end of the diagonal brace 1312 can be connected to the side support column 112, or to the connection between the side support column 112 and the cross beam 121.

[0037] Specifically, as shown in Figure 2, one end of the diagonal brace 1312 is connected to the first right-angle hanging ring group 13121, and the side support column 112 is connected to the second right-angle hanging ring group 1123. 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.

[0038] As shown in Figure 4, the other end of the diagonal member 1312 is connected to the third right-angle hanging ring group 13122, and the first end hardware 180 and the third right-angle hanging ring group 13122 at the other end of the pillar cross arm 1311 are respectively connected to the second connecting plate 184, so that the other end of the diagonal member 1312 is connected to the pillar cross arm 1311.

[0039] Furthermore, as shown in FIG4 , 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 a 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. The voltage equalizing ring 1313 can evenly distribute the high voltage around, ensuring 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.

[0040] In one embodiment, each support column includes a main support column, to which a support crossarm is connected. The support crossarm extends away from the crossbeam. One end of a diagonal brace is connected to the junction of the side support column and the crossbeam, and the other end is connected to the other end of the support crossarm. The diagonal brace, the support crossarm, and the main support column form a stable triangular space. The other end of the support crossarm is used to connect the wires.

[0041] In another specific embodiment, as shown in Figures 1 and 2, each support column 111 includes two main support columns 1113. Each main support column 1113 is connected to a support crossarm 1311. The support crossarm 1311 extends away from the crossbeam 121. The other ends of the two support crossarms 1311 are connected to each other. One end of a diagonal brace 1312 is connected to the connection between the side support column 112 and the crossbeam 121, and the other end is connected to the connection end of the two support crossarms 1311. A stable triangular pyramid space is formed between the diagonal brace 1312, the two support crossarms 1311, and the two main support columns 1113. The connection end of the two support crossarms 1311 is used to hang the wires 200. Preferably, the two support crossarms 1311 are located in the same horizontal plane.

[0042] Furthermore, as shown in FIG2 , the straight line on which the axis of the crossbeam 121 lies is perpendicular to the plane on which the axes of the two main support columns 1113 lie, and an angle of 5° to 70° is formed between the two main support columns 1113. The two main support columns 1113 are connected to the crossbeam 121 via a flange assembly 114. Of the two side support columns 112 located on either side, at least one side support column 112 further includes an oblique support column 1114, which is connected to the flange assembly 114. The oblique support column 1114 is located outside the plane on which the two main support columns 1113 lie to limit the deviation of the substation frame 100 along the extension direction of the crossbeam 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 arranged on the side away from the crossbeam assembly 120 and is located between the two pillar crossarms 1311. In other embodiments, the first side support column may include an oblique support column, or both the first side support column and the second side support column may include an oblique support column to further limit the displacement of the substation frame along the extension direction of the beam. No specific limitation is made here.

[0043] 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. 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.

[0044] In one embodiment, as shown in FIG1 , the crossbeam 121 is made of a composite insulating material. The location on the crossbeam 121 between the two support columns 111 can be directly used as a wire hanging point. Because the crossbeams in traditional substation structures are made of metal, a combination of tension insulator strings, suspension insulator strings, or jumpers are required to hang the conductors. In one embodiment, the crossbeam 121 is made of a composite insulating material with excellent electrical insulation properties. It can directly hang the conductors 200, eliminating the need for structures such as suspension insulators, thereby reducing the material consumption of these structures. Furthermore, by eliminating tension insulator strings, suspension insulator strings, and jumpers, it can also eliminate the problem of windage discharge that may exist in the substation structure 100. The substation structure 100 using composite insulating materials is lightweight, resistant to rust and cracking, and highly efficient to transport and install. It is also maintenance-free throughout its lifecycle, reducing the operating and maintenance costs of existing porcelain insulator strings. Of course, in other embodiments, the crossbeams can also be made of metal, and a combination of tension insulator strings, suspension insulator strings, or jumpers can be used to hang the conductors.

[0045] In one embodiment, as shown in FIG5 , 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 wire hanging plate 1212 , which is arranged at a flange between two adjacent crossbeam sections 1211 . The first wire hanging plate 1212 has a plurality of wire hanging holes, which are used to connect wire hanging fittings (not shown) and then hang the conductors 200 . The conductors are connected to the wire hanging fittings to achieve the wire hanging holes, that is, the first wire hanging plate 1212 forms a wire hanging point. 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 . The first wire hanging plate 1212 is sandwiched between the two first flanges 1213 to hang the conductors 200 . Of course, in other embodiments, the crossbeam can also be a single, continuous beam with a number of spaced-apart clamps, each with a wire-hanging plate positioned on the clamp to create multiple wire-hanging points for connecting wires. Equalizing rings 1313 are also positioned on both sides of the first flange 1213. These rings evenly distribute the high voltage around the flange, ensuring no potential difference between the various parts of the ring, thereby achieving voltage balancing and preventing abnormal discharge.

[0046] In one embodiment, as shown in Figures 1 and 2, the crossbeam 121 gradually rises upward in a direction away from the support columns 111 on both sides to form an arched crossbeam 121. This allows the substation frame 100 to utilize its own arched structure to offset vertical sag, reducing safety hazards. Specifically, a flange assembly 114 is provided between the support columns 111 and the crossbeam 121. The ends of the support columns 111 and the crossbeam 121 are respectively connected to the flange assembly 114. The flange assembly 114 includes a cylindrical body 1141. The axis of the cylindrical body 1141 is tilted upward and forms an acute angle with the horizontal plane. This ensures that the cylindrical body 1141 has an upward pre-arching tendency after installation. When the flange assembly 114 is connected to the crossbeam 121, a coordinated pre-arching angle is generated, allowing the crossbeam 121 to gradually rise upward in a direction away from the support columns 111 on both sides to form the arched crossbeam 121.

[0047] Furthermore, as shown in FIG1 , 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 crossbeam 121 and the second support portion 1112. The first support portion 1111 is made of a composite insulating material, and the second support portion 1112 is made of a metal material. The connection between the first support portion 1111 and the crossbeam assembly 120 can directly serve as a wire hanging point. Of course, in other embodiments, wire hanging points can be set 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 crossbeam 121 is made of a composite insulating material, it has excellent electrical insulation properties, thereby reducing the electrical safety distance between the conductor 200 and the support column 111, 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 a metal material, which can achieve the effect of reducing costs. In addition, the support column 111 of the composite structure is light in weight and not prone to rust and cracking, which solves the problem of difficult transportation, installation and maintenance and reduces the transportation, installation and maintenance costs.

[0048] 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 land acquisition costs.

[0049] It should be noted that the crossbeam 121 and the first support portion 1111 can adopt a post insulator structure. The post insulator includes an internal insulator and a rubber shed wrapped around the insulator. Specifically, the insulator can be an insulating tube or an insulating core rod. The insulating tube can be a glass fiber reinforced plastic tube formed by winding and curing glass fiber or aramid fiber impregnated with epoxy resin, 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 with epoxy resin, or a pultruded core rod formed by pultrusion. The rubber shed can be made of high-temperature vulcanized silicone rubber or other rubber materials. Flanges are provided at both ends of the insulator. The flanges at both ends of the crossbeam assembly 121 are respectively fixedly connected to the two flange assemblies 114 (described below) at both ends of the substation frame 100. The flanges at both ends of the first support portion 1111 are respectively fixedly connected to the flange assembly 114 and the second support portion 1112. The connection can be made by other connecting parts, welding, or a combination of the above connection methods. In other embodiments, the crossbeam 121 and the first support portion 1111 may also be made of other composite insulating materials, which is not limited here.

[0050] To ensure electrical insulation between the conductor 200 connected to the hanging point at the connection between the crossbeam 121 and the first support portion 1111 and the second support portion 1112, as shown in FIG1 , the substation frame 100 further includes a first support insulator 141. The first support insulator 141 includes a first end connected to the support column 111 and a second end opposite the first end. The second end is a free end. The free end of the first support insulator 141 is used to support the conductor 200 connected to the hanging point at the connection between the first support portion 1111 and the crossbeam 121. Preferably, the first support insulator 141 is disposed horizontally, or the free end of the first support insulator 141 is higher than the first end of the first support insulator 141.

[0051] Specifically, as shown in Figures 1 and 3, 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 plate 192. The second sleeve 191 is sleeved and fixed to the end of the first support insulator 141. One end of the second plate 192 is provided with a U-shaped groove that matches 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, without limitation. The second end fitting 190 at the end of the first support insulator 141 connected to the support column 111 is connected to the support column 111 via fasteners.

[0052] Furthermore, as shown in FIG3 , because 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 junction of the first support portion 1111 and the second support portion 1112. A third connecting plate 193 is provided at the junction of the first support portion 1111 and the second support portion 1112, and the second end fitting 190 is connected to the third connecting plate 193 via fasteners. This fully utilizes the height and strength of the second support portion 1112 while facilitating the connection of the first support insulator 141 to the support column 111.

[0053] As shown in FIG1 , the substation structure 100 further includes a second tension insulator 151 . One end of the second tension insulator 151 is mounted on the support column 111 , and the other end is free. 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 made of a composite insulating material and the second support portion 1112 is made of a metal material, the metal second support portion 1112 has higher strength and bearing capacity than the composite insulating first support portion 1111. Therefore, the second tension insulator 151 can be connected to the junction of the first support portion 1111 and the second support portion 1112, thereby fully utilizing the height and strength of the second support portion 1112 and facilitating 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.

[0054] Specifically, as shown in Figure 3, one end of the second tension insulator 151 is connected to the fourth right-angle hanging ring group 1511, and a fourth connecting plate 1512 is provided at the connection between the first support part 1111 and the second support part 1112, and the fourth right-angle hanging ring group 1511 is connected to the fourth connecting plate 1512.

[0055] In other embodiments, the second tension insulator may be disposed on the second support portion or the first support portion.

[0056] 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.

[0057] In another embodiment, as shown in Figure 7, the substation structure 100 further includes a second crossbeam 160, which is installed between two adjacent support columns 111 and below the crossbeam 121. The second crossbeam 160 is made of metal. The substation structure 100 also includes a third tension insulator 152, one end of which is connected to the second crossbeam 160 and the other end is free. The free end of the third tension insulator 152 serves as a wire hanging point. Thus, while the length of the crossbeam 121 remains unchanged, an additional phase conductor 200 can be installed between two adjacent support columns 111. This increases the number of connected conductors 200 phases, reduces the use of crossbeams 121 and support columns 111, reduces the use of steel and foundation materials, and lowers construction costs. Furthermore, it fully utilizes space, compresses the lateral space of the substation structure 100, and reduces the land occupied by the substation. Preferably, the third tension insulator 152 is horizontally connected to the second crossbeam 160.

[0058] In one embodiment, as shown in Figures 7 and 8, a second flange 162 is connected to each end of the second crossbeam 160, 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.
