Description
Technical field
The utility model belongs to transmission line field more particularly to a kind of framework type double loop terminal shaft tower.
Background technique
As shown in Figure 1, outlet structure is under the jurisdiction of Substation Design range, in current project of transmitting and converting electricity to meet outlet structure
The requirement such as load, drift angle, electrical distance of frame, existing transmission line of electricity intervention substation, and will be by one base terminal tower of setting
Line shelves span reduces, tension loosens to realize.
There are problems:
(1) it is limited by outlet structure, transmission line of electricity terminal shaft tower causes its tower because stress condition is different from continuous lever tower
Material and basic earthwork amount are all larger than under equal conditions conventional shaft tower, and span is unable to fully utilize, and causes the increase of construction investment,
In addition outlet need to meet the comprehensive drift angle of substation and require, and outlet freedom degree is limited.
(2) the more base terminal shaft tower dense arrangements in substation outlet, influence planning department to the impression of project of transmitting and converting electricity with
Decision.
(3) framework and terminal shaft tower isolate design so that transmission line of electricity and substation inlet wire shelves there are outlet drift angle, lead
The profession interface problem such as ground wire hanging point position and size, slightly carelessness can hinder the smooth development of engineering construction.
(4) the special outlet structure such as existing substation's outlet prioritization scheme, either " plover type ", " sail association type " is also
It is route outlet planning, terminal shaft tower special designing, it is single to be analyzed from power transformation angle or route angle, to saving work
Journey cost effect is unobvious, while constraining further decreasing for substation's occupied area.
Utility model content
The purpose of this utility model be in view of the deficiencies of the prior art and provide a kind of framework type double loop terminal shaft tower.
To achieve the goals above, technical solution adopted in the utility model is:
A kind of framework type double loop terminal shaft tower, including shaft tower, the shaft tower is four layers of cross-arm, defeated on four layers of cross-arm
Electric line is directly connect with substation, and top layer is ground wire cross-arm, and shaft two sides are equipped with ground wire cross-arm, ground wire cross-arm and shaft
Vertically, and it is located on same vertical face；It is upper phase conductor cross-arm positioned at ground wire cross-arm lower layer, phase conductor cross-arm is located at shaft two on this
Side, phase conductor cross arm end is deviated to transformer substation side on this, and is arranged by axisymmetrical of shaft；Upper phase conductor cross-arm lower layer
For middle phase conductor cross-arm, phase conductor cross-arm is located at shaft two sides on this, and shaft two sides cross-arm is vertical with shaft, and is located at same vertical
In plane；Middle phase conductor cross-arm lower layer is lower phase conductor cross-arm, and lower phase conductor cross-arm is located at shaft two sides, and the lower phase conductor is horizontal
Load is arranged to station lateral offset, and by axisymmetrical of shaft.
Each conducting wire cross-arm is an integral structure.
The upper phase conductor cross-arm and lower phase conductor cross-arm include two connecting rods and a connection ring, two connecting rods difference
It is welded in connection ring, angle is 60-150 degree between two connecting rods.
The connection ring includes the ring body of opening, and the outside bending in ring body both ends, ring body both ends form two after bending
The mounting plates structure being parallel to each other, is machined with the through-hole passed through for bolt on mounting plates structure, and ring body is led to after being socketed in shaft tower
Bolt is crossed to be locked.
The utility model has the beneficial effects that the utility model eliminates transmission line of electricity conventional terminal shaft tower and inlet wire is isolated
Shelves, to shaft tower span is made full use of, reducing project cost has positive effect, while avoiding outgoing line side terminal shaft tower tower position limited
Caused by power transformation station location it is mobile.Substation's tradition framework is eliminated, is had actively to substation's occupied area is further decreased
Meaning.When multiloop outlet, substation's outgoing line side is without redistributing row's terminal shaft tower, so as to improve outgoing line side land use effect
Rate optimizes transmission line of electricity gallery perception.Not by framework, shaft tower outlet is directlyed adopt, outlet drift angle greatly increases, outlet direction
Freedom degree increases.
