The working principle and the beneficial effects of the technical scheme are as follows: in order to further improve the bearing capacity of the first bearing plate 5, considering that when the transformer 4 is installed in the middle of the first bearing plate 5 and stressed, the included angle formed by the transformer and the supporting beam 6 is subjected to a larger bending moment and is easy to break, the elastic supporting component 8 is arranged at the position to form an elastic supporting force so as to reduce the borne bending moment and improve the bearing capacity of the first bearing plate 5;
the arc-shaped elastic plate 810 has certain deformability, deformation can be generated when the bending moment born by the edge of the first bearing plate 5 is overlarge, the arc-shaped elastic plate 810 is compressed, after the arc-shaped elastic plate 810 is deformed, the included angle between two movable rods 830 connected with the arc-shaped elastic plate 810 is reduced, so that the elastic body 840 is extruded, the elastic body 840 can be cylindrical, after the elastic body 840 is deformed, the second spring 860 can be extruded to deform in a compression mode, the fixed plate 850 is compressed to form an impetus, the impetus acts on the arc-shaped elastic plate 810, and under the elastic restoring acting force of the arc-shaped elastic plate 810 and the second spring 860, elastic supporting force can be formed on the first bearing plate 5, so that the bending moment born by the edge of the first bearing plate 5 is reduced, and the bearing capacity is improved;
and when the box-type transformer substation is influenced by the outside or causes the first bearing plate 5 to vibrate, the vibration can be relieved through the elastic supporting component 8, the stress at the edge of the first bearing plate 5 is reduced, and stable support is provided for the transformer 4.
