All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

An embodiment of the present application provides a power transformation framework 100, as shown in fig. 1 and 2, including at least two support assemblies 110 and at least two beam assemblies 120, where the support assemblies 110 are arranged at intervals along a first direction, the beam assemblies 120 are erected between two adjacent support assemblies 110, and the support assemblies 110 support the beam assemblies 120. The beam assembly 120 is used to hitch wires. The at least one support assembly 110 includes a first support portion 111 and a second support portion 112 connected to each other, the first support portion 111 is located between the beam assembly 120 and the second support portion 112, the first support portion 111 is made of a composite insulating material, and the second support portion 112 is made of a metal material. Because the first supporting portion 111 connected to the beam assembly 120 is made of composite insulating material, it has excellent electrical insulating performance, so that the electrical safety distance between the conductive wire and the supporting assembly 110 can be reduced, and further the width and the land acquisition cost of the power transformation frame 100 can be effectively reduced, and meanwhile, the second supporting portion 112 is made of metal material, so that the effect of reducing the cost can be achieved. In addition, the support assembly 110 with the composite structure has light weight and is not easy to rust and crack, so that the problem of difficult maintenance in transportation and installation is correspondingly solved, and the transportation and installation cost is reduced.

In order to further reduce the width of the power transformation framework 100, as shown in fig. 1 and 2, all the support assemblies 110 include a first support portion 111 and a second support portion 112, the first support portion 111 is made of a composite insulating material, the electrical insulation performance of the first support portion 111 is fully exerted, and the electrical safety distance between the conducting wire and the support assembly 110 is minimized, so that the width and the ground charge of the power transformation framework are reduced.

Moreover, the beam assembly 120 is made of a composite insulating material, has excellent electrical insulating performance, can be directly connected with a wire in a hanging mode, does not need to adopt a suspension insulator and the like, has a certain ground height, and can integrally reduce the height of the power transformation framework 100 and reduce the material consumption of the suspension insulator and other structures and the support assembly 110 after the suspension insulator and other wires are cancelled; moreover, strain insulator strings, suspension insulator strings and jumper wires are saved, and the problem of windage yaw discharge possibly existing in the power transformation framework 100 can be solved; the power transformation framework 100 made of the composite insulating material is light in weight, not prone to rusting and cracking, high in transportation and installation efficiency, capable of achieving a full life cycle and free of maintenance, and capable of reducing operation and maintenance costs of an original porcelain insulator chain.

In the traditional power transformation framework, the beam assembly is made of metal materials, and a tension insulator string, a suspension insulator string or a jumper wire is required to be combined to connect a lead, so that the whole height of the power transformation framework is high. In one embodiment, as shown in fig. 1, the beam assembly 120 is made of a composite insulating material, has excellent electrical insulating properties, can be directly connected with a wire without using a structure such as a suspension insulator, and can integrally reduce the height of the power transformation frame 100 and the material consumption of the structure such as the suspension insulator and the material consumption of the support assembly 110 after the wire is not connected with the suspension insulator due to the fixed ground height of the wire; moreover, strain insulator strings, suspension insulator strings and jumper wires are saved, and the problem of windage yaw discharge possibly existing in the power transformation framework 100 can be solved; the power transformation framework 100 made of the composite insulating material is light in weight, not prone to rusting and cracking, high in transportation and installation efficiency, capable of achieving a full life cycle and free of maintenance, and capable of reducing operation and maintenance costs of an original porcelain insulator chain.

The longer the diameter of the beam assembly 120 made of the composite insulating material is, the higher the mechanical strength is, the longer the axial length can be set to set more wire hanging points, and meanwhile, as the diameter is increased, the manufacturing cost is increased sharply, and the material cost is also increased correspondingly. In order to reduce the cost of the beam assembly 120, the power transformation frame 100 further includes an auxiliary support 170, and the auxiliary support 170 is disposed between two adjacent support assemblies 110 and is used for supporting the beam assembly 120, so that under the condition that the distance between the two support assemblies 110 is fixed, the diameter length of the beam assembly 120 provided with the auxiliary support 170 can be set below the first diameter length and is smaller than the diameter length of the beam assembly 120 without the auxiliary support 170, thereby reducing the cost of the beam assembly 120. The overall cost of the power transformation framework 100 is reduced, and the advantages of the composite insulating material are embodied.

In order to maintain the overall performance of the power transformation frame 100, as shown in fig. 1, the auxiliary support 170 includes a first support 171 and a second support 172, the first support 171 is located between the beam assembly 120 and the second support 172, the first support 171 is made of a composite insulating material, and the second support 172 is made of a metal material.

In particular, the insulator may be an insulating tube or an insulating mandrel. The insulating tube can be a glass fiber reinforced plastic tube formed by winding and curing epoxy resin impregnated by glass fiber or aramid fiber or a hollow pultrusion 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 pultrusion core rod formed by pultrusion, and the rubber shed can be made of high-temperature vulcanized silicone rubber or other rubber materials.

In other embodiments, two support assemblies 110 are spaced apart along the first direction, and in this case, the power transformation frame 100 is a single-span power transformation frame 100.

In an embodiment, three or a multiple of three wire hanging points, for example, three, six, or nine, are disposed between two adjacent supporting members 110. Three adjacent wire hanging points are respectively connected with three phases A, B and C, and enough in-phase electrical safety distance needs to be ensured among the three phases A, B and C.

In addition to the two specifications of the power transformation structure 100, after the auxiliary support 170 is disposed on the power transformation structures 100 of the other specifications, the diameter of the beam assembly 100 is significantly reduced, so that the cost of the beam assembly 120 is significantly reduced.

Two string-hanging holes 144 and a prepared hole are formed in the second string-hanging plate 142, the prepared hole is located right below the beam assembly 120, and the two string-hanging holes 144 are symmetrically arranged on two sides of the prepared hole.

In yet another embodiment, the beam assembly 120 may be provided without being divided, i.e., the beam assembly 120 is a strip-type composite post insulator. As shown in fig. 5, the power transformation framework 100 includes an anchor ear 122 and a third wiring board 143, the anchor ear 122 is disposed on the beam assembly 120 in a spaced manner, the third wiring board 143 is disposed on an outer wall of the anchor ear 122, the third wiring board 143 is provided with a plurality of wiring holes 144, and the wiring holes 144 are used for hanging wires.

Of course, in other embodiments, a manner of splicing a plurality of beam sections 121 and combining the hoop 122 may also be adopted, for example, the beam assembly 120 includes a long beam section 121 and a short beam section 121, the long beam section 121 and the short beam section 121 are spliced by a flange, the flange is provided with a first wire hanging plate 141, and the hoop 122 is sleeved on the long beam section 121.

As shown in fig. 3, the wire hanging hole 144 of each wire hanging plate is used for connecting with a wire hanging fitting 210, and the lead wire 200 is hung in the wire hanging hole 144 by the wire hanging fitting 210. The wire hanging hole 144 for hanging the wire hanging fitting 210 on the general wire hanging plate is circular, but considering that the wire hanging fitting 210 may rotate at a certain angle under the action of external force, after the wire hanging fitting 210 rotates, the direction of the force between the wire hanging fitting 210 and each wire hanging plate cannot intersect with the central line of each wire hanging plate, namely, a torsion force is generated on each wire hanging plate, and the force can lead to the connection looseness and even the reduction of the support service life. In order to make after hanging wire gold utensil 210 is rotatory, the direction of force between hanging wire gold utensil 210 and each hanging wire board still intersects with the central line of each hanging wire board, set up at least one hanging wire hole 144 on each hanging wire board into waist shape hole or arc hole in this application, hang wire gold utensil 210 takes place to rotate after automatic removal in hanging wire hole 144 for the direction of the effect of hanging wire gold utensil 210 to each hanging wire board keeps crossing with the central line of each hanging wire board, thereby keep the connection stability of each hanging wire board, strengthen the stability of transformer framework 100, prolong its life.

In order to ensure the mechanical stability of the power transformation framework 100, the central line of each wire hanging plate coincides with the central line of the beam assembly 120, so that the wire hanging holes 144 are arranged to be waist-shaped holes or arc-shaped holes, and the direction of the acting force of the wire hanging hardware fitting 210 on the beam assembly 120 is ensured to be intersected with the central line of the beam assembly 120.

The flange assembly 130 disposed between the support assembly 110 and the beam assembly 120 is likely to cause abnormal discharge near the strong electric field due to the presence of a plurality of irregular contours and the close distance to the first suspension plate 141. As shown in fig. 1, the power transformation frame 100 further includes a shield case 131, and the shield case 131 is covered outside the flange assembly 130 to prevent abnormal discharge.

In addition, as shown in fig. 6, the equalizing ring 160 is further disposed on the cross beam assembly 120 on a side of the second suspension plate 142 away from the flange assembly 130, and the equalizing ring 160 can uniformly distribute high voltage around, so as to ensure that there is no potential difference between each annular portion, thereby achieving an equalizing effect and preventing abnormal discharge.

Further, at least one side of the first suspension plate 141 is also provided with a grading ring 160, respectively, to homogenize an electric field and prevent discharge. Preferably, the first wire hanging plate 141 is provided at both sides thereof with grading rings 160, respectively.

Similarly, at least one side of the third suspension plate 143 is also provided with a grading ring (not shown) to make an electric field uniform and prevent discharge. Preferably, the third wire hanging plate 143 is provided with equalizing rings on both sides thereof.

In one embodiment, as shown in fig. 1 and 4, the beam assembly 120 gradually rises upwards in a direction away from the two side support assemblies 110 to form an arched beam assembly 120, so that the power transformation frame 100 can counteract vertical sag by using its own arched structure, thereby reducing the potential safety hazard. The flange assembly 130 includes a barrel 133, and an axis of the barrel 133 is inclined upward and forms an acute angle with a horizontal plane, so as to ensure that the barrel 133 has a tendency of pre-arching upward after installation, and when the flange assembly 130 is connected with the beam assembly 120, a linked pre-arching angle can be generated, so that the beam assembly 120 can be gradually lifted upward along a direction away from the support assemblies 110 at both sides to form the arched beam assembly 120.

In one embodiment, as shown in fig. 1 and 2, each support assembly 110 includes two main support columns 113, each main support column 113 includes a first support 111 and a second support 112, and first support 111 is a composite insulating material. The two main supporting columns 113 are respectively connected with the flange assembly 130, the plane where the axes of the two main supporting columns 113 are located is perpendicular to the first direction, and an included angle of 5-70 degrees is formed between the two main supporting columns 113.

Further, as shown in fig. 2, at least one of the two support assemblies 110 located at two sides further includes an oblique support column 114, the oblique support column 114 is connected to the flange assembly 130 and includes a first support 111 and a second support 112, and the first support 111 is made of a composite insulating material. The diagonal support posts 114 are located out of the plane of the two main support posts 113 to limit deflection of the power transformation frame 100 in the first direction. It should be noted that the diagonal support column 114 is disposed at a side away from the beam assembly 120.

The power transformation frame 100 needs to be grounded, especially the row-connected power transformation frame 100, when the beam assembly 120 is made of composite insulating material and can be directly connected with the conducting wire, it is important how to connect the ground wire because the ground wire and the conducting wire are required to keep enough electrical safety distance and also considering the lightning protection problem. As shown in fig. 1, in an embodiment, the power transformation framework 100 further includes a wiring pillar 150, the wiring pillar 150 is disposed corresponding to the support component 110, the wiring pillar 150 is made of a composite insulating material, the wiring pillar 150 includes a first end 151 disposed on the support component 110 and a second end 152 opposite to the first end 151, the second end 152 is higher than the beam component 120, and the second end 152 of the wiring pillar 150 is used for hanging a ground wire; the second ends 152 of the wiring posts 150 are electrically connected to each other. Through setting up wiring post 150 to because the second end 152 of wiring post 150 is higher than beam assembly 120's height, thereby the second end 152 of wiring post 150 is higher than the wire height, both can guarantee the electrical safety distance between ground wire and the wire, still can play lightning-arrest effect. Since the wiring posts 150 and the first supporting portion 111 are made of insulating materials, the ground wire needs to be connected to the grounding down-lead 153 to complete grounding, and since the installation process of the wiring posts 150 hooking the grounding down-lead 153 is relatively complicated, after the second ends 152 of all the wiring posts 150 are electrically connected, the grounding down-lead 153 is connected to the grounding point along one of the wiring posts 150, so that the overall grounding of the power transformation frame 100 can be realized, and the installation process is convenient. Of course, in other embodiments, the down conductor 153 may be connected to the ground point along a plurality or all of the wiring posts 150, and is not limited herein.

In order to ensure the stable connection between the wiring posts 150 and the beam assembly 120, the direction of the wiring posts 150 and the axis of the supporting assembly 110 are located on the same straight line, that is, the wiring posts 150 are vertically disposed on the beam assembly 120, the axis direction of the wiring posts 150 is consistent with the gravity direction thereof, the wiring posts 150 can be stably disposed on the supporting assembly 110, and specifically, the wiring posts 150 are disposed on the flange assembly 130 between the supporting assembly 110 and the beam assembly 120.

The ground down-lead 153 may be positioned adjacent to the wiring stud 150 when the electrical safety distance between the first end 151 of the wiring stud and the wire-hanging point on the beam assembly 120 where the wire is hung is sufficient.

In an embodiment, when the power transformation frame 100 is a row power transformation frame 100, three or a multiple of three hanging points for hanging wires, such as three, six, or nine, are disposed between two adjacent supporting assemblies 110. Three adjacent wire hanging points are respectively connected with three phases A, B and C, and enough in-phase electrical safety distance needs to be ensured among the three phases A, B and C. It should be noted that, in order to ensure the electrical safety distance between adjacent connection points, when the power transformation framework 100 is the row power transformation framework 100, no wire hanging point is arranged at the connection point between the flange assembly 130 located at the middle position and the beam assemblies 120 located at both sides, or a wire hanging point is arranged at only one side.

In addition, the two nearest wire hanging points on the two sides of the support assembly 110 at the middle position need to satisfy the inter-phase safe electrical distance of the wires hung on the power transformation frame 100.

It should be noted that, when the distance between the wire hooked at the nearest wire hanging point to the support assembly 110 and the support assembly 110 does not satisfy the safe electrical distance between the ground downlead 153 and the wire, a support structure is further required to be additionally provided to ensure the safe electrical distance between the ground downlead 153 and the wire hooked at the wire hanging point, and the distance between the ground downlead 153 and the wire is required to be greater than a first predetermined value.

Specifically, a post insulator (not shown) is disposed at a connection end of the wiring column 150 and the supporting member 110, the post insulator includes a proximal end disposed at the supporting member 110 and a distal end opposite to the proximal end, a distance between the distal end and the wire is greater than a first predetermined value, and the ground down lead 153 is hooked to the distal end by the second end 152 of the wiring column 150 and then is grounded, so as to ensure a safe electrical distance between the ground down lead 153 and the wire hooked at the wire hanging point.

In summary, the first supporting portion 111 connected to the beam assembly 120 is made of a composite insulating material, which has excellent electrical insulating performance, so that the electrical safety distance between the conductive wires and the supporting assembly 110 can be reduced, and the width and the ground charges of the power transformation frame 100 can be effectively reduced, and the second supporting portion 112 is made of a metal material, which can achieve the effect of reducing the cost. Moreover, the beam assembly 120 is made of a composite insulating material, has excellent electrical insulating performance, can be directly connected with a wire in a hanging mode, does not need to adopt a suspension insulator and the like, and can integrally reduce the height of the power transformation framework 100 and reduce the material consumption of the suspension insulator and the like and the material consumption of the support assembly 110 after the suspension insulator and the like are cancelled due to the fixed ground height of the wire; moreover, because the strain insulator string, the suspension insulator string and the jumper wire are eliminated, the problem of wind deflection discharge possibly existing in the power transformation framework 100 can be solved; the power transformation framework 100 made of the composite insulating material is light in weight, not prone to rusting and cracking, high in transportation and installation efficiency, capable of achieving a full life cycle and free of maintenance, and capable of reducing operation and maintenance costs of an original porcelain insulator chain.

In addition, the auxiliary support 170 is disposed between two adjacent support assemblies 110 and is used for supporting the beam assembly 120, so that the diameter of the beam assembly 120 with the auxiliary support 170 can be set below the first diameter under the condition that the distance between the two support assemblies 110 is constant, which is smaller than the diameter of the beam assembly 120 without the auxiliary support 170, and the cost of the beam assembly 120 is greatly reduced. The overall cost of the power transformation framework 100 is reduced, and the advantages of the composite insulating material are embodied.
