Description
[technical field]
The utility model relates to ultra-high-tension power transmission line technical field, especially a kind of changing suitable for existing single time anchor support
Position special pole.
[background technique]
Tri-phase unbalance factor is to determine one of arrangements of conductors and the principal element of transposition form.Transmission line of electricity three-phase arranges not
Symmetrically, alternate and relatively parameter is different, the imbalance of electric system electric current and voltage will be caused.In order to reduce electric system just
The often degree of asymmetry of voltage and current when operation, and influence of the transmission line of electricity to communication line is limited, transmission line of electricity mostly uses
The mode of transposition.
In practical transmission line of electricity transposition engineering, often using straight line transposition, strain insulator transposition, hanging transposition and additional bypass
Jumper wire rack transposition all refers to a newly-built base and the different shaft tower of traditional tower structure, therefore in built line disconnection, reconfiguration engineering
In, since parameter etc. adjusts over the ground for transmission line length, conducting wire, exist and remove built transposition tower, exchange point reconstruction is newly being selected to change
The problem of position tower.
[utility model content]
The main purpose of the utility model is to provide a kind of transposition special poles suitable for existing single time anchor support, pass through
It is being close to create base transposition special pole at existing conventional single-loop anchor support, it is real using facilities such as jumper string, post insulator strings
It replaces between existing conducting wire.Compared to traditional scheme, when line disconnection, reconfiguration, it is only necessary to remove transposition special pole and adjustment connects
Line avoids transposition tower from removing and rebuild.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of transposition special pole suitable for existing single time anchor support, including shaft, cross-arm, support insulator and conducting wire branch
Stay tube, the cross-arm are located at the top of shaft, and one side cross-arm is arranged in horizontal path direction, backwards to built anchor support direction and a back edge
Phase conductor arranges one side cross-arm in 30 degree of angles, arranges on one side backwards to built anchor support direction and another back edge phase conductor in 30 degree of angles
Cross-arm, three side cross-arm equal lengths, the support insulator are fixed on the ending on replace dedicated club body top and three side cross-arms,
The wire support pipe in horizontal path direction is provided with backwards to built anchor support direction both sides cross-arm upper supporting column insulator end.
Compared with prior art, the utility model has the beneficial effects that 1) being suitble to be close to anchor support construction, it is suitable for small angle tower
Anchor support；2) using transposition special pole, while wire jumper is adjusted, realizes wire transposition；3) it compared with traditional scheme, is greatly reduced and builds
If expense, reduce occupied area；4) solve the problems, such as that the split type transposition tower of traditional scheme can not find suitable tower position in mountain area.
5) construction and installation are relatively easy, are easy to overhaul.
[Detailed description of the invention]
Fig. 1 is the structure and wiring overall schematic of the utility model.
[specific embodiment]
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, a kind of transposition special pole suitable for existing single time anchor support, including shaft 1, cross-arm 2, pillar are exhausted
Edge 3 and wire support pipe 4.
The cross-arm 2 is located at the top of shaft 1, and one side cross-arm is arranged in horizontal path direction, backwards to built anchor support direction with
One back edge phase conductor arranges one side cross-arm in 30 degree of angles, is in 30 degree of angle cloth backwards to built anchor support direction and another back edge phase conductor
One side cross-arm is set, three side cross-arm angles are in 60 degree, and equal length.
The support insulator 3 is fixed on the ending on replace dedicated 1 top of club body and three side cross-arms 2, backwards to built resistance to
Cross-arm upper supporting column insulator 3 end in the direction Zhang Ta both sides is provided with the wire support pipe 4 in horizontal path direction.
Existing single loop anchor support 5 increases the wire jumper insulator string 7 of a ribbon support tube newly in 5 taper of side phase conductor cross-arm, uses
In side phase conductor commutation, while wire jumper insulator string 8 at top layer ground wire cross-arm 6 being utilized to be used for middle phase conductor commutation.
The shaft height, support insulator length and wire spacing meet the requirement of electric clearance, lightning protection.
The dedicated rod structure of transposition as shown in Figure 1 and wiring schematic diagram.
When being replaced using built shaft tower, it is being close to create one between single loop route anchor support a side phase line
Base transposition special pole, phase conductor in existing single loop anchor support 5 is connected on 6 side wire jumper insulator string 8 of top layer ground wire cross-arm, in
Phase conductor is forwarded to left side phase conductor by wire jumper insulator string 8, realizes transposition；By existing 4 left side phase of single loop anchor support
Conducting wire is connected at 5 wire jumper insulator string 7 of the left side with support tube of side phase conductor cross-arm, and left side phase conductor passes through the jump with support tube
Line insulator string 7 is connected at dedicated 1 three side cross-arm of club body, the 2 ending support insulator 3 of transposition and wire support pipe 4, is then connected to
Right edge phase conductor realizes wire transposition；Existing 4 right edge phase conductor of single loop anchor support is connected to 5 left side of side phase conductor cross-arm
At wire jumper insulator string 7 with support tube, right edge phase conductor is connected to by the support insulator 3 on dedicated 1 top of club body of replacing
Middle phase conductor realizes wire transposition.
When removing transposition special tower cancellation transposition, built transposition special pole, existing single loop anchor support 4, benefit are removed
With at top layer ground wire cross-arm 6 wire jumper insulator string 8 connection in phase conductor, utilize 5 wire jumper of the taper with support tube of side phase conductor cross-arm
Insulator string 7 is connected to ipsilateral middle phase conductor.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included in the protection scope of the utility model.
