Description
Technical field
The present invention relates to a kind of ADSS optical cable installation auxiliary devices, more specifically, it relates to a kind of steel tower ADSS light
Cable unloads power device.
Background technique
Currently, ADSS optical cable is set up with electric power tower, optical cable is fixed by fitting and every level-one steel tower, and both ends steel tower is in
Between angle tower ADSS optical cable held to bear the running tension of optical cable using strain hardware fitting, the tangent tower of middle section is using outstanding
It hangs down fitting hanging ADSS optical cable and is not subject to the running tension of optical cable.For steel tower, ADSS optical cable gets over its horizontal pull
It is small better, the excessive stability that will affect steel tower of pulling force, and we can only pass through increasing by the degree for adjusting optical cable stringing now
Big arc sag reduces the pulling force to steel tower.But ADSS optical cable operations specification has strict demand, the excessive easy band of arc sag to optical cable arc sag
Carry out problems, such as: lower safe distance is reduced, optical cable windage yaw increases, optical cable abrasion aggravation etc..Therefore, up to the present,
At home and abroad there is no a kind of effective methods, to reduce ADSS optical cable to the pulling force of steel tower.
Chinese patent notification number CN204832624U discloses a kind of high voltage overhead power transmission sequence ADSS optical fiber cable fitting string
And its connection structure, the preformed armor rods wire clamp including at least ADSS optical cable and for fixing ADSS optical cable, further include be connected to it is pre-
The connector of hank knotting wire clamp, be connected to the hanging plate of connector with and be serially connected with hanging plate for the link fixed with shaft tower, link
It is embedded in hanging plate.Withouyt insulator in hardware string, the alternation charge of ADSS optical cable appearance induction can constantly flow at any time
Enter ground, avoid due to the alternation charge of accumulation is breakdown and the problem of scorification optical cable, improve the safety of optical cable operation,
Optical cable operating cost has been saved simultaneously.But it is not suitable for intermediate angle tower, arc easily occurs using rear ADSS optical cable for a long time
It hangs down excessive phenomenon.
Summary of the invention
The present invention overcomes both sides deficiencies, first is that, when ADSS optical cable is mounted on steel tower, to the horizontal pull of steel tower
It is larger, influence the stability of steel tower；Second is that easily there is the excessive phenomenon of arc sag using rear ADSS optical cable for a long time, one is provided
Kind steel tower unloads power device with ADSS optical cable, and ADSS optical cable is mounted on steel tower by unloading power device, substantially reduces the water to steel tower
Horizontal drawing power, reduces the influence to iron tower stability, and ADSS optical cable arc sag it is excessive when can adjust automatically unload power device
Length reduces ADSS optical cable arc sag, ADSS optical cable is made to be less prone to the excessive phenomenon of arc sag to tense ADSS optical cable.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme: a kind of steel tower unloads power dress with ADSS optical cable
It sets, including connecting rod, is connected to length-adjustable two adjusting rod in connecting rod both ends, the pulling ring being connected on adjusting rod,
Two pulling rings are all connected with the support ring for being mounted on steel tower, pull ring activity to be hooked in support ring, pull and connect on ring
Tension has preformed armor rods, and preformed armor rods connect ADSS optical cable, and two preformed armor rods tense connecting rod.
When ADSS optical cable is installed on steel tower, first support ring is installed on steel tower, preformed armor rods connection is fastened to ADSS
On optical cable, then preformed armor rods end is connected to and is pulled on ring, the length of adjusting rod is adjusted, makes connecting rod, adjusting rod, preformed armor rods
In tension, while ensuring that the arc sag of ADSS optical cable is met the requirements.It is subject to according to force analysis support ring preformed
Silk horizontal pull f=2sin(0.5a) * F, a be preformed armor rods and connecting rod extended line angle, F is preformed armor rods pulling force, that is, ADSS
The running tension of optical cable.As can be seen from the above equation, when preformed armor rods and connecting rod extended line angle are 0 degree, what support ring was subject to
Preformed armor rods horizontal pull f is 0, unloads power completely, steel tower is solely subjected to the gravity from ADSS optical cable vertical direction at this time；Work as preformed armor rods
When with connecting rod extended line angle less than 60 degree, f < F has the effect of unloading power, and steel tower bears vertical from ADSS optical cable at this time
The lesser pulling force of gravity and horizontal direction in direction；When preformed armor rods and connecting rod extended line angle are greater than 60 degree, f > F does not have
The effect of power is unloaded, steel tower bears gravity and the biggish pulling force of horizontal direction from ADSS optical cable vertical direction at this time.Therefore
ADSS optical cable ensures preformed armor rods and connecting rod extended line angle a less than 60 degree, when angle a is zero degree, i.e., in straight line iron when installing
When power device is unloaded in installation on tower, steel tower can use strain insulator gold not by the horizontal pull of ADSS optical cable on tangent suspension tower at this time
Tool production ADSS optical cable static side, advantageously reduces ADSS optic cable design, difficulty of construction, promotes ADSS optical cable project benefit.Steel tower
The gravity for the vertical direction being subject to will not influence the stability of steel tower.In conclusion ADSS optical cable is pacified by unloading power device
Mounted in steel tower, the horizontal pull to steel tower is substantially reduced, the influence to iron tower stability is reduced, is conducive to extend steel tower
