Specifically, the beam assembly 1000 is used for hanging wires, and a three-phase wire (not shown) is hung on one beam assembly 1000, and the three-phase wire is hung at two ends of the second composite insulator 1120 and the triangular wire hanging plate 1220, respectively. The triangular composite cross beam hanging wire structure can more effectively utilize the space of the framework, and the span of the framework is greatly shortened on the premise of keeping the phase ground and the interphase distance unchanged, so that the occupied area of the framework is reduced; meanwhile, under the same stress condition, the moment of the composite cross beam is shortened to the maximum extent, the bending moment applied to the root of the composite insulator is reduced, the number of framework materials is further reduced, and lower cost can be guaranteed under the condition that the supporting strength and the structural stability are improved.

In one embodiment, referring to fig. 3, the number of the auxiliary members 1200 is one, and one end of the auxiliary member 1200 is connected to the second composite post insulator 1120, and the other end is a free end. Specifically, the second composite post insulator 1120 is provided with an anchor ear 1121, the anchor ear 1121 is provided with a connecting member 1122, and the auxiliary member 1200 is fixedly connected to the anchor ear 1121 through the connecting member 1122.

Further, the beam assembly 1000 with a trapezoidal structure can overcome the sag problem caused by the vertical force applied to the power transformation frame 100. Specifically, the power transformation frame 100 still needs to bear the self weight of the beam assembly 1000 and the weight of the hardware and wires hung on the beam assembly 1000 in the vertical direction, and these vertical forces may cause the beam to sag downward. When the sag is large, the ground distance of a lead hooked on the beam assembly 1000 may be smaller than a standard safety distance, so that the sag generated due to stress can be offset by the trapezoidal structure on the original structural design, and the safety of a hanging wire can be ensured.

Further, a flange assembly 3000 is arranged between the support assembly 2000 and the beam assembly 1000, and the support assembly 2000 and the beam assembly 1000 are fixedly connected through the flange assembly 3000.

The flange assembly 3000 disposed between the supporting assembly 2000 and the beam assembly 1000 is likely to cause abnormal discharge near a strong electric field due to the presence of a plurality of irregular contours. As shown in fig. 1, the power transformation frame 100 further includes a shielding case 3001, and the shielding case 3001 covers the flange assembly 3000 to prevent abnormal discharge.

In addition, as shown in fig. 1, grading rings are further disposed on two sides of the first composite insulator 1110, the second composite insulator 1120, and the third composite insulator 1130, and the grading rings can uniformly distribute high voltage around the grading rings, so that no potential difference exists between each annular part, thereby achieving a grading effect and preventing discharge.

Further, at least one side of the auxiliary member 1200 may also be provided with a grading ring to homogenize an electric field and prevent discharge from occurring. Preferably, the auxiliary member 1200 is provided at both sides thereof with grading rings, respectively.

Further, in one embodiment, as shown in fig. 1, each support assembly 2000 includes two support columns 2001, the two support columns 2001 are respectively connected to the flange assembly 3000, the plane of the axes of the two support columns 2001 is perpendicular to the first direction, and the two support columns 2001 form an included angle of 5 ° to 70 °. In other embodiments, each support assembly 2000 may further include three or more support columns 2001, and the number of the support columns 2001 is not particularly limited, and the beam assembly 1000 may be stably supported.

Further, at least one of the two support assemblies 2000 fixedly connected to the ends of the beam assembly 1000 further includes an auxiliary support column 2002, and the auxiliary support column 2002 is located out of the plane of the two support columns 210 to limit the displacement of the power transformation frame 100 along the first direction. In addition, since the power transformation frame is very high, in order to facilitate maintenance, a ladder stand (not shown) is further provided on the auxiliary support column 2002, so that a maintenance worker can climb up the power transformation frame through the ladder stand to perform maintenance and repair operations.

It should be noted that each beam assembly 1000 is provided with three or a multiple of three wire hanging points, for example, three, six, or nine wire hanging points. Three adjacent wire hanging points are respectively connected with three-phase wires A, B and C, and enough in-phase electrical safety distance needs to be ensured among the three phases A, B and C. Besides, a safe electrical distance between phases needs to be ensured between each loop (one loop comprises three phases A, B and C). Specifically, the wire hanging point may be directly disposed on the composite post insulator, or the hanging point may be disposed on a connection node between the composite post insulators, which is selected according to the actual situation, and is not limited herein.
