As shown in fig. 4, the wire hanging hole 144 of each wire hanging plate is used for being connected with the wire hanging fitting 210, and the wire hanging hole 144 of the ordinary wire hanging plate for hanging the wire hanging fitting 210 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, that is, a torsion force is generated on each wire hanging plate, and the force can lead to loose connection and even reduce the support 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 first suspension plate 141 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, as shown in fig. 6, at least one side of the second wire hanging plate 142 is also provided with a grading ring 160, respectively, to homogenize an electric field and prevent discharge from occurring. Preferably, the second wire hanging plate 142 is provided with equalizing rings 160 at both sides thereof, respectively.

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 power transformation frame 100, when the beam assembly 120 is made of composite insulating material and can be directly connected with the wires, it is important how to connect the ground wires because the ground wires and the wires need to keep enough electrical safety distance and also consider the problem of lightning protection. As shown in fig. 7, 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 of the supporting assembly 110 connected to the beam assembly 120 is made of a composite insulating material, which has excellent electrical insulating properties, so that the electrical safety distance between the conductive wires and the supporting assembly 110 can be reduced, and the width and the land charge of the power transformation frame 100 can be effectively reduced, and the second supporting portion 112 is made of a metal material, thereby achieving the effect of reducing the cost.
