Description
Technical field
The utility model relates to a kind of 110kV circuit double back and becomes single steel tower.
Background technology
For implementing amphitypy design concept, saving and take up an area, improve unit corridor power delivery capabilities, multi-circuit lines on the same tower application is more and more universal.In same corridor, circuit adopts wiring on the same tower as far as possible, and while walking footpath difference, intermediate diagonal, subdivided member pylon is established, and has reached like this planning unified, rationally distributed, the requirement of concentrating cabling.Becoming single time steel tower for many times becomes and is singly most widely used with double back again.Traditional design is single time steel tower of the two change of specialized designs, and selects a kind of structure and the close tower of single time steel tower of stressed and two changes to substitute, and mostly conventionally is double-loop terminal tower.In substituting, this tower is checked to reinforcement or restrictive condition.Because being substitutes, its intensity, rigidity, stability can not meet engine request completely, make engineering specifications use limited owing to substituting the characteristic of tower simultaneously.Therefore design a kind of special single time steel tower of two change is necessary very much.
Conventional design double back become single tower divide hole mainly with average corner bisectrix or hard-over bisecting line minute hole, due to hanging wire point position and corner, cannot once determine, often there will be design institute to go out foundation pits plan view angle and construction is not inconsistent and confirmation repeatedly.More seriously often there will be because the phenomenon that foundation pits mistake appears in design idea is not understood in construction well, also to design, cause harmful effect, a traditional minute hole side has increased more field process amount.Therefore, single time steel tower of two changes minute hole mode is also had to improved necessity.
Utility model content
The purpose of this utility model is to provide a kind of 110kV circuit double back and becomes single steel tower, can meet 110kV double back and become single requirement of engineering.
A kind of 110kV circuit double back becomes single steel tower, comprise tower body, its special feature is: thus wherein on tower body, be provided with two ground wires that two hanging points articulate single loop side, on this tower body, be provided with in addition ground wire cross-arm, and below this ground wire cross-arm, be provided with three cover strain cross arms.
Wherein ground wire cross-arm and three cover strain cross arms all adopt symmetrical cross-arm or all adopt asymmetric cross-arm.
The utility model provides a kind of 110kV of being specifically designed to double back to become single steel tower, and tower performance conforms to completely with engineering specifications, avoids tower to substitute, to greatest extent engineering demands.And this new tower divides hole mode reasonable, and field conduct is convenient, effectively reduces field process amount, increases work efficiency.Advantage and the beneficial effect of the utility model steel tower also comprise: 1, single loop side adopts normal safety factor, can save shaft tower, by the normal span bar position of arranging.2, two ground wires in single time side four ground wires are hung on after tower body, effectively reduce cross-arm and tower body is stressed, greatly reduce steel tower technical indicator.3, adopt new minute hole mode, field operation location workload is obviously lowered, greatly improved the operating efficiency of measuring in field operation with electric specialty.4, this tower, for transformer station's outlet, divides hole mode by this tower, and plane is rationally attractive in appearance.5, except meeting intensity, greatly improved bending resistance, the torsional rigidity performance of steel tower, strengthened the reliability of steel tower and engineering, the structural instability of avoiding steel tower to substitute generation destroys.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of steel tower in the utility model;
Accompanying drawing 2 is the structural representation of steel tower in the utility model.
The specific embodiment
As shown in Figure 1, 2, the utility model is that a kind of 110kV circuit double back becomes single steel tower, comprise tower body 2, thereby wherein on tower body 2, be provided with two ground wires that two hanging points articulate single loop side, on this tower body 2, be provided with ground wire cross-arm 1 in addition, and below this ground wire cross-arm 1, be provided with three cover strain cross arms 3, ground wire cross-arm 1 and three cover strain cross arms 3 all adopt symmetrical cross-arm (referring to Fig. 1) or all adopt asymmetric cross-arm ginseng (see figure 2).
In the utility model, two of single loop side ground wire hanging points are all located on tower body 2, and four ground wires of single loop side are not all at same hanging point.On tower body 2 tops, ground wire cross-arm 1 is installed, three cover strain cross arms are also installed below this ground wire cross-arm 1.Tower of the present utility model can contain two kinds of cross-arms, and wherein asymmetric cross-arm is used for double conversion list, and symmetrical cross-arm becomes single for horn mouth.Hanging hole design on steel tower, can meet multiple hanging wire mode.
The using method of the utility model steel tower is:
1) after two circuit last base steel tower tower position of 110kV (double back becomes single steel tower tower position) determined, on Center stake, set up full station measuring instrument.
2) backsight is aimed at after shelves alignment stake, left and right is dialled 90 ° and by cross-arm hanging point, apart from the distance at steel tower center, determine that double back divides that Dan Huihou is mono-hangs back a stake position on this both direction, and hammers into timber.
3) measuring instrument of entirely standing is set up in respectively two hanging point stake positions, backsight is rear apparent direction to dial backward 90 ° on Center stake, as rear apparent direction, horizontally rotates single time, alignment lens the place ahead steel tower Center stake, the anglec of rotation is accurate circuit corner, and left and right is identical.
4) after position, four base centers being separated by the vertical rear shelves direction of cross-arm, cast basis, the vertical steel tower of group.
5) on steel tower, hang gold utensil, insulator, ground wire is installed, ground wire is hung on the hanging point of four diverse locations.
6) treat all vertical complete wires that sets up of group of whole strain section steel tower.
Claims (2)
1. a 110kV circuit double back becomes single steel tower, comprise tower body (2), it is characterized in that: wherein at tower body (2) thus on be provided with two ground wires that two hanging points articulate single loop side, on this tower body (2), be provided with in addition ground wire cross-arm (1), and be provided with three cover strain cross arms (3) in this ground wire cross-arm (1) below.
2. 110kV circuit double back as claimed in claim 1 becomes single steel tower, it is characterized in that: wherein ground wire cross-arm (1) and three cover strain cross arms (3) all adopt symmetrical cross-arm or all adopt asymmetric cross-arm.
