Problems solved by technology
The above setting not only results in heavier product weight, but also further increases the bending moment load at the hanging point, and when the operating condition is too large, the above setting is prone to excessive hanging point offset, which does not meet the requirements of the design standard for the substation frame. At the same time, it will cause the bolts at the flange connection to be overstressed and fail.
In addition, the large size of the straight beam also increases the product cost and limits the overall promotion of the substation structure.

The invention specifically discloses a power transformation framework which comprises a supporting assembly, a middle beam and a connecting beam. The supporting assembly comprises a first supporting piece and a second supporting piece which are spaced in a first direction. The middle beam is disposed between the first supporting piece and the second supporting piece. The middle beam comprises a first end and a second end which are opposite in the first direction. The connecting beam comprises a first connecting part and a second connecting part. The first connecting part is connected with thefirst end and the first supporting piece. The second connecting part is connected with the second end and the second supporting piece. Moreover, the first connecting part and the first supporting piece define a triangle with the first end as the vertex. The second connecting part and the second supporting piece define a triangle with the second end as the vertex. Thus, the triangles are more stable in structure, the specification of the power transformation framework is further reduced, and manufacturing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a power transformation framework. Background technique [0002] As one of the main equipment in the substation, the substation frame is used to suspend conductors, support conductors or switchgear and other electrical equipment. [0003] The beams in the existing substation structure are usually spliced in-line beams. When the load of the hanging point is large, the size of the in-line beam needs to be designed larger. The above setting not only results in heavier product weight, but also further increases the bending moment load at the hanging point, and when the operating condition is too large, the above setting is prone to excessive hanging point offset, which does not meet the requirements of the design standard for the substation frame. At the same time, it will cause the bolts at the flange connection to be overstressed and fail. In additi...
