Description
【Technical field】
Under drawing the present invention relates to ultra-high-tension power transmission line technical field, especially a kind of cable for built single time anchor support
Special pole.
【Background technology】
In the Practical Project under overhead transmission line cable draws, influenced by line route, ambient enviroment etc. factor,
Cable draws lower point and possibly is present at circuit center, built the shaft tower positions such as nearby, especially near built anchor support when, create resistance to
It opens type cable termination tower and forms small isolated shelves with built anchor support, built anchor support both sides unbalanced tensile force is made to increase, it is difficult to is full
Sufficient use condition need to remove reconstruction；Newly-built linear type cable termination is influenced each other with built anchor support by pole and tower foundation, between two towers
Away from should not be excessively close, and newly-built tangent tower utilization rate be high, serious waste of resources, and overall aesthetics is poor.
It is therefore proposed that a kind of cable for built single time anchor support draws lower special pole, influenced most on built anchor support
On the basis of small, under realizing that single back line cable draws.
【Invention content】
The main purpose of the present invention is to provide a kind of cables for built single time anchor support to draw lower special pole, is suitble to tight
Anchor support construction is pasted, does not change and draws downside anchor support stress, the dismounting for avoiding old tower is rebuild, with newly-built straight line, anchor support phase
Than construction cost is greatly reduced, reduces floor space.
To achieve the above object, the technical solution that the present invention takes is：
A kind of cable for built single time anchor support draws lower special pole, including shaft, lower layer's cross-arm, upper layer cross-arm, seat
Formula cable termination and A seating arrester, the upper layer cross-arm are placed in the top of shaft, and both sides cross-arm, institute are arranged in parallel circuit direction
The lower section that lower layer's cross-arm is placed in upper layer cross-arm is stated, arranges four side cross-arms in 60 degree of angles with built circuit, four side cross-arms are in X-type point
Cloth, the upper layer cross-arm ending are separately installed with A seating cable eventually with A seating arrester, and lower layer's cross-arm is towards a side phase
The cross-arm ending of conducting wire fixes A seating cable termination and A seating arrester respectively.
Further, it is connected with conducting wire or copper coin between the upper layer cross-arm A seating cable termination and A seating arrester.
Further, lower layer's cross-arm is located at available wire between the A seating cable termination and A seating arrester of the same side
Or copper coin connection.
Compared with prior art, beneficial effects of the present invention：1) cable draws lower special pole and is suitble to be close to anchor support construction；2)
Realize that single loop T connects, cut-offs and the multiple functions such as reconfiguration；3) do not change and draw downside anchor support stress, avoid the dismounting of old tower
It rebuilds；4) compared with newly-built straight line, anchor support, construction cost is greatly reduced, reduces floor space；5) dry cable terminal is used
Structure is compared, and it is more extensive to be applicable in voltage class.
【Description of the drawings】
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is that the present invention coordinates wiring schematic diagram with built single loop strain insulator steel tower.
【Specific implementation mode】
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
A kind of cable for built single time anchor support as shown in Figs. 1-2 draws lower special pole, including shaft 1, lower layer's cross
Load 2, upper layer cross-arm 3, A seating cable termination 5 and A seating arrester 4.
The upper layer cross-arm 3 is placed in the top of shaft 1, and both sides cross-arm is arranged in parallel circuit direction；Lower layer's cross-arm 2 is set
In the lower section of upper layer cross-arm 3, arranges that four side cross-arms, four side cross-arms are distributed in X-type in 60 degree of angles with built circuit, be conducive to cross-arm
Fixation is easily installed on shaft 1, it is advantageously ensured that between cross-arm ending A seating cable termination 5, A seating arrester 4, shaft 1
Electrical distance is conducive to that upper layer cross-arm 3 is coordinated to fix A seating cable termination 5, A seating arrester 4, is effectively compressed whole height.
3 ending of upper layer cross-arm installs A seating cable termination 5 and A seating arrester 4, A seating cable termination 5 and seat respectively
Available wire or copper coin connect between formula arrester 4, under the drawing for middle phase conductor.
2 taper of the lower layer's cross-arm installation A seating cable termination 5 and A seating arrester 4, the cross towards a side phase conductor
It carries on a shoulder pole ending and fixes A seating cable termination 5 and A seating arrester 4 respectively, A seating cable termination 5 and the A seating for being located at the same side are lightning-arrest
Available wire or copper coin connect between device 4, under the drawing for side phase conductor.
1 height of shaft of the present invention, cross-arm length are by electrical distance, cross-arm between A seating cable termination 5 and A seating arrester 4
Parameter that electrical distance, A seating cable termination 5 and A seating arrester 4 between built single loop tension tower conducting wire are arranged etc. is certainly
It is fixed.
When built single loop strain insulator steel tower T connects, reconfiguration scheme when, as shown in Fig. 2, in built single loop circuit anchor support one
A base cable is created between the phase line of side and draws lower special pole, and middle phase conductor, which is connected to cable, to be drawn at the cross-arm of lower special pole upper layer
At cable termination, side phase conductor is connected at the cable termination of cable Yin Xia special poles lower layer cross-arm.
When built single loop strain insulator steel tower cut-offs scheme, between the phase line of built single loop circuit anchor support two sides
A base cable is created respectively and draws lower special pole, and middle phase conductor, which is connected to cable, draws cable termination at the cross-arm of lower special pole upper layer
Place, side phase conductor is connected at the cable termination of cable Yin Xia special poles lower layer cross-arm, while by built single loop line tension
Tower wire jumper is unlocked.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should be included within the scope of the present invention.
