Of course, in other embodiments, each cross beam may also include one, three or more insulators, and the insulators in different cross beams may be fixedly connected by the same connecting member or may be fixedly connected by a plurality of different connecting members, which is not specifically limited herein, depending on actual requirements.

Specifically, the first connecting member 1101 is a flat plate structure, two sets of circular through holes corresponding to the plurality of flange holes on the end flange 1111 are formed in the plate surface of the first connecting member 1101, the end flanges 1111 at one ends of the two composite insulators 1110 on the same beam 1100 are symmetrically arranged on two sides of the first connecting member 1101, and are respectively attached to two side surfaces of the first connecting member 1101. The circular through hole is matched with the flange hole in the end flange 1111 in size, and a fastener sequentially penetrates through the flange hole in the end flange 1111 at one end of the composite insulator 1110 on one side of the first connecting piece 1101, the circular through hole in the first connecting piece 1101 and the flange hole in the end flange 1111 at one end of the composite insulator 1110 on the other side of the first connecting piece 1101 so as to tightly connect the two composite insulators 1110 to form a beam 1100.

In the same beam assembly 1000, the composite insulators 1110 in the two beams 1100 are connected to each other by the same first connecting member 1101. Two crossbeams 1100 are through same first connecting piece 1101 interconnect, can be so that two crossbeams 1100 of fastening connection when two composite insulator 1110 on same crossbeam 1100 of fixed connection of first connecting piece 1101 for beam assembly 1000 has stronger stability, and mechanical properties is better, also is favorable to the parallel arrangement of two crossbeams 1100.

Further, two ends of the two beams 1100 are fixedly connected by two second connectors 1102 respectively to form the beam assembly 1000. Specifically, the second connecting member 1102 on the left side in fig. 1 is a flat plate structure, two flanges are disposed on the side surface of the second connecting member 1102 close to the beam assembly 1000, and the end of one beam 1100 is fixedly connected to one flange, so that the two beams 1100 are fixed to each other to form the beam assembly 1000. Specifically, a plurality of flange through holes are formed in the flange, the flange through holes are arranged corresponding to a plurality of flange holes in the end flange 1111 at the other end of the composite insulator 1110, and the composite insulator 1110 is fixedly connected with the second connecting member 1102 by sequentially penetrating the fastening members through the corresponding flange through holes and the corresponding flange holes. Of course, other connection manners may be adopted, referring to fig. 1, the second connection member 1102 on the right side is a flat plate-shaped structure, two sets of circular through holes or bolt holes are provided on the second connection member 1102, the circular through holes or bolt holes are matched with the flange holes of the end flange 1111, and the end of one cross beam 1100 is fixedly connected with one set of circular through holes or bolt holes, so that the two cross beams 1100 are fixed to each other to form the cross beam assembly 1000. Specifically, the size and specification of the circular through hole/bolt hole and the flange hole on the end flange 1111 are matched, and the composite insulator 1110 and the second connecting member 1102 are fixedly connected by sequentially passing a fastener through the flange hole on the end flange 1111 at the other end of the composite insulator 1110 and the circular through hole/bolt hole on the second connecting member 1102. In other embodiments, fixed connection manners such as welding, clamping and fixing connection and the like may also be adopted, and the two ends of the cross beam are both fixedly connected by using the end flange and the flange plate or both fixedly connected by using the end flange and the circular through hole/bolt hole on the second connecting piece in a matching manner, so that specific connection manners are not specifically limited, as long as two cross beams can be fixedly connected to form a cross beam assembly.

Since the power transformation frame 100 is mainly subjected to a horizontal tensile force, in order to improve the tensile strength of the beam assembly 1000 in the horizontal direction, the axes of the two beams 1100 are disposed in the same horizontal plane. Of course, in other embodiments, the axes of the two beams may be disposed in the same vertical plane, and are not limited in this regard.

In order to meet the installation requirement, an appropriate distance is kept between the end flanges 1111 at the same ends of two adjacent composite insulators 1110 on different beams 1100, so as to avoid interference between the adjacent composite insulators 1110. Meanwhile, based on the requirement of structural stress, the distance between the circular through hole on the first connecting piece 1101 and the edge of the first connecting piece 1101 needs to be greater than or equal to 1.5d, that is, greater than or equal to 1.5 times the diameter of the circular through hole, and/or the distance between the circular through hole or bolt hole on the second connecting piece 1102 and the edge of the second connecting piece 1102 needs to be greater than or equal to 1.5d, that is, greater than or equal to 1.5 times the diameter of the circular through hole or bolt hole. The distance requirements are different according to the diameter of the circular through hole or the bolt hole. Due to the arrangement, the stress of the first connecting piece 1101 and/or the second connecting piece 1102 can be more reasonable, the bending or the fracture in the normal installation or use process can be avoided, and the stress strength can be ensured.

Further, the support assembly 2000 includes two side supports 2100, and two ends of the cross beam assembly 1000 are respectively fixedly connected to the two side supports 2100 through two flange assemblies 3000. Specifically, one side of the second connecting member 1102, which is far away from the beam assembly 1000, is provided with a flange plate, the second connecting member 1102 is fixedly connected with the flange assembly 3000 through the flange plate, and the side support 2100 is fixedly connected with the flange assembly 3000, so that the beam assembly 1000 is fixedly connected with the support assembly 2000.

Further, each side support 2100 comprises two support columns 2110, the two support columns 2110 are respectively connected with the flange assembly 3000, the plane of the axes of the two support columns 2110 is perpendicular to the extending direction of the cross beam assembly 1000, and an included angle of 5-70 degrees is formed between the two support columns 2110. In other embodiments, each support assembly may further include one or more intermediate supports supported at locations other than the ends of the beam assembly; meanwhile, the side supporting pieces and the middle supporting pieces can also comprise one or more supporting columns, the number of the supporting pieces and the number of the supporting columns are not particularly limited, and the cross beam assembly only needs to be stably supported.

Preferably, in order to reinforce the mechanical strength of the side support 2100, a reinforcing member 2220 is further disposed between the two supporting columns 2110, and the reinforcing member 2220 is disposed at the middle portion of the two supporting columns 2110 and fixedly connects the two supporting columns 2110. The number of the reinforcing members 2220 in each side support 2100 may be one or more, and is not particularly limited herein, subject to practical requirements.

Further, each of the supporting columns 2110 includes a first supporting portion 2111 and a second supporting portion 2112, the first supporting portion 2111 is located between the beam assembly 1000 and the second supporting portion 2112, and the first supporting portion 2111 is made of a composite insulating material and has good electrical insulating performance; the second support portion 2112 is made of a metal material, which has good mechanical strength and is low in cost. Because first supporting portion 2111 is composite insulation material, therefore the position of first supporting portion 2111 and crossbeam subassembly 1000 interconnect can directly articulate the wire, not only can reduce the area that transformer framework 100 was covered up to because the wire directly articulates the tip at crossbeam subassembly 1000, can also reduce the moment that produces because of the wire articulates, reduce the intensity design requirement to crossbeam subassembly 1000. Compared with the support columns with all-metal structures, the mixed support column can ensure the number of the hanging wires and simultaneously reduce the floor area of the composite power transformation framework; compared with the supporting column with a full composite structure, the hybrid supporting column can reduce the cost of the composite power transformation framework under the condition of the same floor area. Therefore, the hybrid support column combines the advantages of the two materials, makes up for the deficiencies of each other, and realizes the optimal combination.

Further, the at least one side support 2100 further comprises a diagonal support 2120, the diagonal support 2120 being configured to limit displacement of the power transformation frame 100 in an extension direction of the beam assembly 1000. One end of the inclined strut 2120 is fixedly connected to the flange assembly 3000, and the other end is fixedly disposed on the ground and extends in a direction away from the beam assembly 1000 along the axial direction of the beam assembly 1000, so as to limit the axial deviation of the power transformation frame 100.

The cross brace 2120 comprises a first support section 2121 and a second support section 2122, the first support section 2121 is located between the beam assembly 1000 and the second support section 2122, and the first support section 2121 is made of a composite insulating material and has good electrical insulating performance; the second support section 2122 is made of metal, which has good mechanical strength and low cost. Of course, in other embodiments, a diagonal support may be provided on both side support assemblies, and is not limited in this respect.

Preferably, in order to ensure the overall structural strength of the power transformation frame 100, the beam assemblies 1000 are symmetrically arranged along the central plane of the support assembly 2000, that is, the beam assemblies 1000 are symmetrically arranged along the vertical plane where the central lines of the two side supports 2100 are located, so that the stress of the power transformation frame 100 is relatively balanced, and the service life of the power transformation frame 100 is ensured.

Further, in order to optimize the structural stress and fully exert the supporting capability of each beam 1100, when the beams 1100 in the beam assembly 1000 are arranged up and down, different beams 1100 in one beam assembly 1000 can be set to different specifications. Preferably, the beam 1100 far from the support assembly 2000 may be configured as a smaller diameter structure, and the beam 1100 near the support assembly 2000 may be configured as a larger diameter structure, depending on the force direction of the beam assembly 1000. By setting the diameter of the beam 1100 far away from the support assembly 2000 to be smaller than the diameter of the beam 1100 near the support assembly 2000, the stress of the power transformation frame 100 can be more balanced, and the overall structure is more stable.

Meanwhile, the cross beam 1100 is used for hanging wires and mainly bears the pulling force from the wires in all directions, and the cross beam 1100 deforms under the stress condition, so that a certain distance needs to be kept between the cross beams 1100 in the cross beam assembly 1000, and the distance needs to be larger than the maximum deformation deviation value generated after the cross beam 1100 is stressed, so that mutual interference between the cross beams 1100 is avoided.

In order to hang the wires, two wire hanging holes are formed in the first connecting piece 1101 and the second connecting piece 1102, the wire hanging holes are formed in the bottom edges of the first connecting piece 1101 and the second connecting piece 1102 and close to two end points, and the wire hanging holes can be used for being directly connected with a wire hanging fitting so that the wires can be hung on the beam assembly 1000. Preferably, the wire hanging holes are waist-shaped holes, so that the tension direction of the wires is always intersected with the center line of the cross beam assembly 1000 under the condition that the wires swing along with wind, the tension direction always passes through the center line of the cross beam assembly 1000, the overall stress of the cross beam assembly 1000 is balanced, and the service life of the power transformation framework 100 is prolonged.

Preferably, in order to enhance the force-bearing capacity of the cross beam assembly 1000, in addition to increasing the diameter of the cross beams 1100 or increasing the number of the cross beams 1100, the tensile properties of the cross beam assembly 1000 can be increased by enhancing the structural strength of the cross beams 1100 themselves. Specifically, this can be achieved by reinforcing the structural strength of the beam 1100 or directly reinforcing the mechanical strength of the material of the beam 1100, i.e., the mechanical strength of the composite insulator 1110 itself. For example, the beam 1100 structure may be divided into a multi-section structure, and connecting members and supporting members are added between the sections, so as to reduce the moment, reduce the stress strength of the beam assembly 1000, and ensure the service life of the power transformation framework 100.

Further, in order to enhance the mechanical strength of the composite insulator 1110 itself, a reinforced post composite insulator having a steel pipe provided therein may be used, and the structural strength of the insulator may be enhanced by the strength of the steel itself.

Generally, a post composite insulator includes an inner insulator and a shed covering the outer portion of the insulator. When the inner insulator is the insulating core rod, the inner insulator can be a solid core rod formed by winding or pultrusion of glass fiber or aramid fiber impregnated epoxy resin; when the inner insulator is an insulating tube, the insulating tube can be a hollow tube formed by winding, curing and molding glass fiber or aramid fiber impregnated epoxy resin or pultrusion.

In order to enhance the mechanical strength of the post composite insulator, a steel pipe may be added to the insulator inside the post composite insulator to form a reinforced post composite insulator. Specifically, in order to ensure the insulating property of the post composite insulator, the steel pipe needs to be fixedly arranged inside the insulator of the post composite insulator, the length of the steel pipe needs to be smaller than that of the insulator, the diameter of the steel pipe needs to be smaller than that of the insulator, and the electrical insulating property of the reinforced post composite insulator after the steel pipe is added also needs to meet actual requirements.

In order to improve the mechanical properties of the beam assembly 1000, more beams 1100 may be disposed in the beam assembly 1000, referring to fig. 2, in another embodiment, the beam assembly 1000 includes three beams 1100, the three beams 1100 are respectively disposed on three vertices of a regular triangle, the beams 1100 are disposed in parallel, and the beam assembly 1000 is overall triangular prism-shaped; each beam 1100 comprises two composite insulators 1110, and the two composite insulators 1110 on the same beam 1100 are connected with each other through a first connecting piece 1101 to form the beam 1100.

In this embodiment, the first connecting member 1101 is a triangular plate structure, two ends of the composite insulator 1110 are respectively provided with an end flange 1111, and the end flange 1111 is provided with a plurality of flange holes. Three groups of circular through holes corresponding to the plurality of flange holes in the end flange 1111 are formed in the plate surface of the first connecting piece 1101, the end flanges 1111 at one ends of the two composite insulators 1110 on the same cross beam 1100 are symmetrically arranged on two sides of the first connecting piece 1101 and are respectively attached to two side surfaces of the first connecting piece 1101. The circular through hole is matched with the flange hole in the end flange 1111 in size and specification, and a fastener sequentially penetrates through the flange hole in the end flange 1111 at one end of the composite insulator 1110 on one side of the first connecting piece 1101, the circular through hole in the first connecting piece 1101 and the flange hole in the end flange 1111 at one end of the composite insulator 1110 on the other side of the first connecting piece 1101 so as to be tightly connected with the two composite insulators 1110 on the same beam 1100 to form the beam 1100. In the same beam assembly 1000, the composite insulators 1110 in the three beams 1100 are all connected to each other by the same first connecting member 1101. The three beams 1100 are connected with each other through the same first connecting piece 1101, so that the first connecting piece 1101 can be fixedly connected with the three beams 1100 while being fixedly connected with the composite insulator 1110, the beam assembly 1000 has stronger stability, and the mechanical property is better.

Further, two ends of the three beams 1100 are respectively and fixedly connected by two second connectors 1102 to form the beam assembly 1000. Specifically, the second connecting member 1102 on the left side in fig. 2 is a triangular plate-shaped structure, three flanges are disposed on the side of the second connecting member 1102 close to the beam assembly 1000, and the end of one beam 1100 is fixedly connected to one flange, so that the three beams 1100 are fixed to each other to form the beam assembly 1000. Specifically, a plurality of flange through holes are formed in the flange, the flange through holes are arranged corresponding to a plurality of flange holes in the end flange 1111 at the other end of the composite insulator 1110, and the composite insulator 1110 is fixedly connected with the second connecting member 1102 by sequentially penetrating the fastening members through the corresponding flange through holes and the corresponding flange holes. Referring to fig. 2, the second connection member 1102 on the right side is a triangular plate-shaped structure, three sets of circular through holes or bolt holes are formed in the second connection member 1102, the circular through holes or bolt holes are matched with the flange holes of the end flange 1111, and the end of one cross beam 1100 is fixedly connected with the circular through holes or bolt holes, so that the three cross beams 1100 are fixed to each other to form the cross beam assembly 1000. Specifically, the size and specification of the circular through hole/bolt hole and the flange hole on the end flange 1111 are matched, and the composite insulator 1110 and the second connecting member 1102 are fixedly connected by sequentially passing a fastener through the flange hole on the end flange 1111 at the other end of the composite insulator 1110 and the circular through hole/bolt hole on the second connecting member 1102.

The beam assembly 1000 is pulled horizontally and also needs to bear the gravity of a wire in the vertical direction, so that the total stress direction is in a plane perpendicular to the axis of the beam assembly 1000 and inclines downwards, one beam 1100 in the beam assembly 1000 is horizontally arranged above, the other two beams 1100 are horizontally arranged below, and a stable triangular structure is formed between the three beams 1100, so that the structure of the beam assembly 1000 is more stable. Of course, in other embodiments, the position distribution of the three beams may also be not a triangular distribution, and may be a vertical arrangement distribution or a horizontal arrangement distribution, which is not specifically limited herein, depending on actual requirements.

Meanwhile, in order to optimize the internal stress of the beam assembly 1000, three beams 1100 within the same beam assembly 1000 are set to different dimensional specifications, that is, the three beams 1100 have at least two different diameters. Since the direction of the force applied to the power transformation frame 100 is a combination of a horizontal pulling force and a vertical downward gravity, the force applied to the two beams 1100 located below is greater than the force applied to the one beam 1100 located above. Based on this force requirement, the diameter of two beams 1100 below is set larger than the diameter of one beam 1100 above. The mode of arranging the beam 1100 with a larger diameter at a position with strong stress can fully exert the mechanical property of the beam assembly 1000, so that the best use is made of the material.

Each beam 1100 may include one, two or more composite insulators 1110, and the two or more composite insulators 1110 are connected to each other by a first connecting member 1101; a plurality of beams 1100 are fixedly connected to each other by a second connector 1102 to form the beam assembly 1000. Except for the difference in the number of the cross beams 1100 in the cross beam assembly 1000 and the difference in the shape of the connecting members, the overall structure of the transforming frame 100 in this embodiment is substantially the same as that in the previous embodiment, and will not be described again.

The composite insulator 1110 is made of a composite material, and due to the characteristics of the composite material, the manufacturing cost of the composite insulator 1110 increases rapidly as the diameter of the composite insulator 1110 increases, so that the cost can be reduced significantly while the mechanical strength is ensured by combining a plurality of small-diameter composite insulators 1110 instead of one large-diameter composite insulator. In other embodiments, the number of the cross beams may also be four or more, and the relative position between the cross beams may also be changed according to actual requirements.

In another embodiment, a beam assembly 1000 may further include four beams 1100, the four beams 1100 are respectively disposed at four vertices of a trapezoid, and the beams 1100 are disposed in parallel. Preferably, the four beams 1100 are arranged in an equilateral trapezoid, and the four beams 1100 are respectively arranged in parallel at two different horizontal heights. Preferably, the diameters of the two beams 1100 located below are larger than the diameters of the two beams 1100 located above, the upper base (short side) of the equilateral trapezoid is located above, and the lower base (long side) of the equilateral trapezoid is located below, so as to fully utilize the mechanical properties of the beams 1100.

In an actual substation, the number of wires entering and exiting from the substation is very large, so many transformation frames 100 are required to support the wires, and in an actual project, in order to save land, the beam assembly 1000 in the transformation frame 100 is usually long, so that one transformation frame 100 can be hooked with more wires of a loop. In another embodiment, as shown in fig. 3, more composite insulators 1110 can be disposed in each beam 1100 to increase the length of the beam assembly 1000, and the corresponding number of first connectors 1101 for connecting the composite insulators 1110 is also greater, so that more wires can be hooked. Preferably, since each loop is composed of A, B, C three phases, in order to hang the wires of the same loop on the same transformation framework 100, the number of wire hanging points provided on each transformation framework 100 is 3 or 3 times. For example, in an embodiment, five composite insulators 1110 may be disposed in one beam 1100, the five composite insulators are sequentially connected to each other through four first connecting members 1101 to form one beam 1100, two ends of each beam 1100 are fixedly connected through second connecting members 1102 to form a beam assembly 1000, and each of the four first connecting members 1101 and the two second connecting members 1102 is provided with a wire hanging hole to form six wire hanging points for hanging two loops.

If the length of the beam assembly 1000 is simply increased, the supporting strength of the power transformation frame 100 is reduced, and therefore, in order to ensure the supporting strength of the power transformation frame 100, as shown in fig. 5, the supporting assembly 2000 includes one or more middle supporting members 2200 in addition to the two side supporting members 2100, that is, one beam assembly 1000 is erected on a plurality of supporting members, thereby enhancing the supporting strength of the power transformation frame 100.

In another embodiment, more loops of wires can be hooked by providing at least two power transformation frames 100 along the extension direction of the beam assembly 1000. The side supports 2100 of two adjacent power transformation frames 100 are disposed in close proximity.

Further, when the side supports 2100 of two adjacent power transformation frames 100 are closely arranged and the side supports 2100 include the diagonal supports 2120, each of the diagonal supports 2120 occupies a certain area, so that the floor area of the power transformation frame 100 can be reduced by changing the structure of the diagonal supports 2120 and using one end support to be fixedly connected to two adjacent power transformation frames 100 at the same time.

Specifically, at least two power transformation frames 100 are disposed along the extending direction of the beam assembly 1000, and an end support (not shown) is disposed between two adjacent power transformation frames 100, and the end support includes an X-shaped composite support and an X-shaped metal support. Wherein the center plane of the end support is parallel to the axis of the cross-beam assembly 1000. Two ends above the X-shaped composite support are respectively and fixedly connected to the ends of the two adjacent side supports 2100 of the two adjacent power transformation frames 100, which are connected to the cross beam assembly 1000, and two ends below the X-shaped composite support are respectively and fixedly connected to the upper surfaces of the reinforcing members 2220 of the two adjacent side supports 2100; two tip of X type metal support top are fixed in the lower surface of reinforcement 2220 in adjacent avris support 2100 respectively to two tip with X type composite support below correspond the setting and make composite support and metal support's central plane be located same vertical plane, can avoid leading to inside bending force of reinforcement 2220 because of stress point difference between them, two tip of X type metal support below all fixed connection are subaerial, thereby restrict the axial skew of power transformation framework 100 and support two adjacent power transformation frameworks 100 simultaneously.
