Description
Technical field
This utility model is related to a kind of high voltage power transmission field, especially relates to a kind of elasticity double string part and elasticity double string pendency
Tower.
Background technology
In the Transmission Line Design of mountain area, tangent tower is generally according to the series planning of 4+1 tower.For meet electrical body and steel tower it
Between clearance requirement, each tower kvTypically between 0.5～0.8,1# tower takes large values value value, and 4# tower gets the small value.
Mountain area transmission line of electricity is complicated due to topographic features, and hypsography is larger, tangent tower vertical span often
Less, horizontal span is larger, kvValue is less than the condition setting when tower is planned.Now vertical load is less, its water to wire
Flat displacement constraint is not enough, and angle of wind deflection under each operating mode for the conventional drop insulator chain will be greater than initial planning limit value, occurs powered
The not enough situation in gap between body and steel tower.In conventional engineering experience, conventional solution installs weight additional, raises straight line
Tower, use k insteadvThe less tower of value and cut-offfing for anchor support etc..Wherein the first three processing method scope of application is fairly limited, and
And all can increase tower weight to a certain extent, although anchor support cut-offs the use demand that can meet in most cases, institute
The tower weight increase leading to is also most, and economic angle exists certain waste.
Utility model content
The purpose of this utility model is: the problem existing for prior art, provides a kind of elasticity double string part and elasticity
Double string pendency towers, solve mountain area transmission line of electricity and are commonly present drape plot tower kvValue is less than normal, and insulator chain windage yaw angle is big, electrical body
The problem that gap and steel tower between is unsatisfactory for requiring.
The purpose of this utility model is achieved through the following technical solutions:
A kind of elasticity double string part is it is characterised in that this pair of string part includes rigid insulation substring, elastic insulated substring and pendency
Wire clamp, described rigid insulator series winding is connected on one end of suspension clamp, and elastic insulated substring is connected to the other end of suspension clamp.
As further technical scheme, the two ends of described rigid insulation substring are connected to a u-shaped link, wherein
One u-shaped link is connected to one end of suspension clamp by right-angle hanging ring, and another u-shaped link is connected with eb link plate.
As further technical scheme, described elastic insulated substring includes rigid insulation substring and spring mechanism, and this is firm
Property insulator chain one end connect suspension clamp, other end connecting spring mechanism.
As further technical scheme, the two ends of rigid insulation substring are connected to a u-shaped link, one of
U-shaped link is connected to one end of suspension clamp by right-angle hanging ring, and another u-shaped link is connected to one end of spring mechanism, bullet
The other end of spring mechanism passes through a u-shaped link and connects eb link plate.
As further technical scheme, described suspension clamp is aluminum alloy suspension clamp.
It is characterised in that this tower includes tower body, this tower body is provided with least two cross-arms to a kind of double pendency tower of going here and there of elasticity,
Flexible double string part is connected between neighbouring cross-arm.
As further technical scheme, the rigid insulator series winding of elasticity double string part connects cross-arm, elastic insulated substring
Connect lower cross-arm.
Compared with prior art, this utility model has the advantage that
1st, solve drape plot tower k wellvBe worth insulator chain windage yaw angle less than normal big when, between electrical body and steel tower
Gap be unsatisfactory for require problem.
2nd, reduce steel tower consumptive material, reduce construction costs.
Brief description
Fig. 1 is the structural representation of elasticity double string part；
Fig. 2 is the structural representation of elasticity double string pendency tower.
Specific embodiment
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment
This utility model provides a kind of elasticity double string part, and this elasticity double string part adopts Conventional insulation substring and elastic insulated son
String combines, and both are connected into " i " type arrangement, and its elastic non-conductive substring is Conventional insulation substring and spring mechanism connects some gold
Tool transformation forms.
As shown in figure 1, this pair string part mainly by rigid insulation substring 3 (i.e. Conventional insulation substring), elastic insulated substring and
Suspension clamp 6 forms.Rigid insulation substring 3 is connected to one end of suspension clamp 6, and elastic insulated substring is connected to suspension clamp 6
The other end, suspension clamp is used for clamping wire.Suspension clamp is aluminum alloy suspension clamp.
In the present embodiment, the two ends of rigid insulation substring 3 are connected to a u-shaped link 2, one of u-shaped link
It is connected to one end of suspension clamp 6 by right-angle hanging ring 4, another u-shaped link is connected with eb link plate 1 (also has one on eb link plate
Individual u-shaped link, for being connected with the u-shaped link of rigid insulation substring 3).
The elastic insulated substring of the present embodiment includes rigid insulation substring 3 and spring mechanism 5, this rigid insulation substring 3
One end connects suspension clamp 6, other end connecting spring mechanism 5.Specifically, the two ends of rigid insulation substring 3 are connected to one
Individual u-shaped link 2, one of u-shaped link is connected to one end of suspension clamp 6 by right-angle hanging ring 4, and another u-shaped link is even
It is connected to one end of spring mechanism 5, the other end of spring mechanism 5 passes through a u-shaped link connection eb link plate (also has one on eb link plate
U-shaped link, for being connected with the u-shaped link of spring mechanism 5).
In addition, the present embodiment also provides a kind of elasticity double string pendency tower, as shown in Fig. 2 this tower includes tower body 201, this tower
Body 201 is provided with least two cross-arms 202, connects flexible double string part 203 between neighbouring cross-arm 202.The double string of elasticity
The rigid insulator series winding of part 303 connects cross-arm, and elastic insulated substring connects lower cross-arm.Because rigid insulation substring hangs over upper horizontal stroke
Load, elastic insulated substring is hung on lower cross-arm, therefore using elasticity double string parts steel tower more than common drape plot tower one layer of horizontal stroke
Load.
In the case of calm, upside rigid insulator provides holding power upwards for wire to this elasticity double string pendency tower, under
The elastic insulated son in side does not stress.And under having wind operating mode, wire is subject to wind action that sidesway occurs, and insulator is driven to offset.
Now upside rigid insulator will with cross-arm hanging point as axis rotation, and downside elastic insulated son except rotate in addition to, spring mechanism
Elastic deformation occurs simultaneously, and rotational angle is bigger, its deformation is bigger, and the pulling force being provided is also bigger.When upper and lower both sides are exhausted
When the pulling force of edge, wire and insulator wind load, vertical load reach balance, insulator stops continuing skew.
Spring mechanism using the cylinder stranded wire helical spring being rolled by cable wire, multi-strand spring have more preferable intensity and
Unique absorbing, effectiveness in vibration suppression, it is now widely used in vibratory equipment, high accuracy table top and require vehicle of smooth transport etc., its
Reliable for transmission line safety, tired and vibrationproof is functional.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model it should refer to
Go out, all any modification, equivalent and improvement made within spirit of the present utility model and principle etc., all should comprise
Within protection domain of the present utility model.
