In the embodiment of the invention, the axial section of the first single truss 3 is perpendicular to the axial section of the second single truss 4, and the axial section of the first a-frame is perpendicular to the axial section of the second a-frame.

In the embodiment of the present invention, the first single truss 3 is arranged in 3 rows, that is, m=3, which are respectively an incoming truss, an intermediate truss, and an outgoing truss.
As the number of columns of the first single truss frames 3 connected in series through the first cross beams 5 increases along with the first array region, the restraining force applied to the first cross beams 5 in the process of thermal expansion and contraction is accumulated, and a larger temperature effect is caused.
In another embodiment of the present invention, referring to fig. 6, the power distribution apparatus site combined frame further includes a third supporting frame 6, a fourth supporting frame 7, a third single frame 8, and a second beam 9.

Because the fourth end support framework 7 and the first end support framework 1 are mutually independent, the first cross beam 5 and the second cross beam 9 are mutually independent, the restraint force accumulation of the first cross beam 5 and the second cross beam 9 in the thermal expansion and contraction process can be reduced, the side force caused by the restraint force accumulation is reduced, and the stability of the combined framework of the whole power distribution device field is improved.
In addition, because the temperature effect is greatly reduced, the requirements on the strength and the cross section area of the first end stay 11, the second end stay 21, the third inclined stay 22 and the fourth inclined stay 23 can be reduced, the consumable materials of the first end stay 11, the second end stay 21, the third inclined stay 22 and the fourth inclined stay 23 are reduced, and the cost is saved.
