Frame.
Background technology
Existing 110KV and 220KV transformer substation framework load is little, frequently with the common iron of material Q235B.Commonly
The shortcoming of steel is mainly manifested in following two aspects：
1st, fire resistance is poor.The thermal conductivity factor of steel is much larger than the thermal conductivity factor of armored concrete（It is about armored concrete
40 times）.The mechanical property of steel, such as yield point, compression strength, elastic modelling quantity and load capacity etc. can be with the risings of temperature
Can drastically decline, generally in 600oC about when steel will lose carrying effect.
2 corrosion-resistant：Steel are easy in corrosion in the environment of air or the environment of humidity.Mainly due to steel
The iron atom on surface and the oxygen of in the air are bound up open-textured oxidation iron rust, particularly when in the air contains soda acid salt
Medium when situation even more serious.Corrosion not only makes steel surface produce uneven corrosion, and the corrosion of local cause should
Power is concentrated, and promotes the premature degradation of steel construction.The seriously corroded of steel endangers the use safety of framework, in design 110KV and
During the framework of 220KV transformer station, steel structure member and node need to carry out complex surface treatment, and need to carry out week
The anti-corrosion protection of phase property and maintenance.
And existing transformer substation framework and conductive cable contacts position are suspension ring, cable cable when mobile is rubbed with suspension ring
Wipe larger, is worn and torn in cable top layer larger, leaky easily occurs, there is larger potential safety hazard.Therefore, it is necessary to it is right
The form of 110KV and 220KV transformer substation framework is studied, and proposes a kind of new framework classes.
Utility model content
The purpose of this utility model be the one kind providing for the deficiency of existing transformer substation framework be applied to 110KV and
The transformer substation framework of 220KV.
To achieve these goals, technical solution adopted in the utility model is：
A kind of transformer substation framework being applied to 110KV and 220KV, including one or two employing stainless steel with supporting

Plane, connects truck transom by ring flange between adjacent two truss columns, is equipped with ground terminal interface in each truss column upper end,
Ground terminal is connected with ground terminal interface, hanging wire ring is connected with truck transom.
Three described pin truss columns include two one-tenth frameworks of A shape structures and a support bar, become the framework of A shape structure by two
Root pipe and the connecting rod composition connecting between two pipes, are connected with connecting rod between support bar and two pipes.
The L-shaped steel by two stainless pipes and between two stainless pipes for the described truck transom are constituted, L
Shape welded steel, between two stainless pipes, is easy to the walkway board walked in the laying of truck transom upper surface.
It is welded with the suspension member of arc or v-shaped structure below described each truck transom, hanging wire ring is movably connected in this extension
On part, a turning set is socketed with hanging wire ring, the hanging wire ring positioned at the two ends of turning set is provided with and limits cable deviation
Block.
Described turning set is respectively metal level, insulating barrier, metal level from the outside to the core, and described insulating barrier is plastic material
Make, be formed in one between the inside and outside metal level of turning set and insulating barrier structure.
It is connected with lightning rod at least on a ground terminal.
In the side of truck transom, railing is installed.
A truss column side is provided with oblique cat ladder at least in.
It is equipped with vertical ladder in various places terminal side.
The beneficial effects of the utility model：The utility model transformer substation framework adopts stainless steel to replace the common iron can be from
Fundamentally solve the problems, such as steel construction corrosion, and the complicated surface treatment operations such as application can be removed from, be capable of extending structure
Service life, reduces overall life cycle cost.With respect to common carbon steel, stainless chemical composition mainly increased alloy
Elemental chromium（Cr）, nickel（Ni）, manganese（Mn）And molybdenum（Mo）, make the material behavior of the two there is a great difference, stainless steel material has
Following characteristics：
（1）Good corrosion resistance, durability, resistance to elevated temperatures.Stainless steel residual strength under the high temperature conditions is with just
Degree is superior to common straightcarbon steel, can apply to fire protection design, reduces the use of fireproof coating.
（2）Early stage is relatively costly, but life cycle management has cost advantage.Because stainless steel material unit price is higher, stainless
The first current cost of steel construction is about 4 ~ 6 times of identical normal steel structure, but if comparing the overall life cycle cost of the two, that is, comprehensive
Close and consider that material cost, structure service life, maintenance cost, antirust and fire prevention process and the full structure such as recycle and use the longevity
All expenses in the life time limit, stainless steel structure has larger advantage.
