Power transformation framework

Abstract

The invention particularly discloses a power transformation framework. The power transformation framework comprises a supporting assembly, a middle cross beam and a connecting cross beam, wherein thesupporting assembly comprises a first supporting piece and a second supporting piece which are arranged at an interval in the first direction; the middle cross beam is arranged between the first supporting piece and the second supporting piece, and comprises a first end and a second end which are opposite in the first direction; and the connecting cross beam comprises a first connecting part and asecond connecting part, the first connecting part is connected with the first end and the first supporting piece, and the second connecting part is connected with the second end and the second supporting piece. Moreover, the space between the first connecting part and the second supporting piece forms a triangular pyramid with the first end as the vertex, and the space between the second connecting part and the second supporting piece forms a triangular pyramid with the second end as the vertex. Therefore, the space of the triangular pyramids is more stable, meanwhile, the specification of the power transformation framework is further miniaturized, and thus the 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...

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.
