Description
Technical field
The utility model is related to transformer substation framework fields, and in particular to be used for the combined frame work of 500 kilovolts of HGIS substations.
Background technology
Current 500 kv substation outlet structure pulling force usually >=50kN, the height of outlet structure is in 26m or so.Currently,
When power distribution equipment uses HGIS patterns, the stress system that end is supportted is arranged in traditional framework scheme generally use.For example,《It is typical
Design》In truss column all using steel pipe inverted Y-shaped column form, be framed in and laterally form Lateral Resistant System by 3 row herringbone columns,
Longitudinal supportted by end provides lateral resisting；《Universal design》It is middle that lateral side column is changed to single steel pipe column by herringbone column, by intermediate herringbone column
Lateral resisting is provided, is supportted by side column end in longitudinal direction and lateral resisting is provided.
In addition, state's net new technology in 2015, propose to use angle steel tower anti-lateral displacement, though this scheme cancels end support, exist with
Lower disadvantage：Steel angle structure connection is complicated, and installation period is long；Middle span root opens larger, land resource waste；Conducting wire sets up situation
Under, structural system center stressed is larger, and rolled steel dosage reduces unobvious compared to traditional scheme.
500 kilovolts of outlet structures in the prior art can be seen as beam-column hinged space bent structure, wherein herringbone column
Or end support root is opened in 6m or so.Therefore, conventional 500 kilovolts of HGIS outlet structures are by calculating general outlet structure herringbone column's
Uplift force is slightly larger than uplift force in 1000kN or more, by pressure.In terms of stress upper angle, rod structure main material stress is mainly axis
Power, bending resistance are not utilized rationally；Beam generally regards the truss structure of both ends freely-supported as, and maximal bending moment concentrates on span centre position
It sets, beam-ends bending resistance does not also utilize rationally；In terms of floor space angle, conventional scheme increases by 10% than support body system for no reason
The land area of left and right, and since the presence of end support is unfavorable for distant view enlarging.
Therefore, if working out one kind not only having saved occupation of land, but also the frame system of saving steel is current skill urgently to be resolved hurrily
Art problem.
Invention content
The purpose of this utility model is to provide a kind of saving and takes up an area, saving steel for 500 kilovolts of HGIS substations
Combined frame work.
To achieve the above object, the utility model uses following technical scheme：One kind being used for 500 kilovolts of HGIS power transformations
The combined frame work stood, including core tower and be arranged in the steel pipe A columns group on core tower periphery, single steel pipe column, the core tower position
In entire HGIS frame systems center, steel pipe A column groups are located at interposition horizontal and vertical in entire HGIS frame systems
It sets, remaining edge framework is all made of single steel pipe column, between the core tower and steel pipe A column groups, steel pipe A columns group and single steel pipe column
Between, be attached by frame girder between two adjacent single steel pipe columns, the steel pipe A columns group by multiple A pole units according to
Minor tick arranges in a row, is attached by frame girder between two neighboring A pole units.
Due to using the technology described above, rigidity is all carried out between core tower, steel pipe A columns group, single steel pipe column and frame girder
Connection constitutes the whole framework stress system just connect, and stress system is changed into steelframe by bent structure, reduces column bottom moment of flexure, by
Power is reasonable, saving steel amount；Surrounding cancels end support, takes up an area smaller, and be conducive to extend.
