Description

A kind of elastic double string parts and elastic double string pendency tower
Technical field
The present invention relates to a kind of high voltage power transmission field, especially relate to a kind of elastic double string parts and elastic double string pendency tower.
Background technology
In the Transmission Line Design of mountain area, tangent tower is planned generally according to 4+1 tower series.For meet electrical body and steel tower it Between clearance requirement, each tower KVValue value is typically between 0.5~0.8, and 1# tower takes large values, and 4# tower gets the small value.
Mountain area transmission line of electricity is complicated due to topographic features, and hypsography is relatively big, tangent tower vertical span often occurs Less, horizontal span is relatively big, KVThe condition set when value is planned less than tower.Now vertical load is less, its water to wire Flat displacement constraint is not enough, and conventional drop insulator chain angle of wind deflection under each operating mode will be greater than initial planning limit value, occurs charged The situation that between body and steel tower, gap is not enough.In conventional engineering experience, conventional solution installs weight additional, raises straight line Tower, use K insteadVTower that value is less 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, but institute The tower weight increase caused is also most, and economic angle exists certain waste.
Summary of the invention
It is an object of the invention to: the problem existed for prior art, it is provided that a kind of elastic double string parts and elastic double string Pendency tower, solves mountain area transmission line of electricity and is commonly present drape plot tower KVBeing worth less than normal, insulator chain windage yaw angle is big, electrical body and ferrum The problem that gap between tower is unsatisfactory for requiring.
The goal of the invention of the present invention is achieved through the following technical solutions:
A kind of elastic double string parts, 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 connects 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, the other end connect spring mechanism.
As further technical scheme, the two ends of rigid insulation substring are connected to a U-shaped link, one of them 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 connects EB link plate by a U-shaped link.
As further technical scheme, described suspension clamp is aluminum alloy suspension clamp.
A kind of elastic double string pendency towers, it is characterised in that this tower includes tower body, and this tower body is provided with at least two cross-arm, Flexible double string part is connected between neighbouring cross-arm.
As further technical scheme, the rigid insulator series winding of elastic double string parts connects cross-arm, elastic insulated substring Connect lower cross-arm.
Compared with prior art, the invention have the advantages that
1, drape plot tower K is well solvedVBe worth insulator chain windage yaw angle less than normal big time, between electrical body and steel tower Gap be unsatisfactory for require problem.
2, reduce steel tower consumptive material, reduce construction costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of elastic double string part;
Fig. 2 is the structural representation of elastic double string pendency tower.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
The present invention provides a kind of elastic double string parts, and this elasticity double string part uses Conventional insulation substring to tie with elastic insulated substring Closing, both are connected into " I " type and arrange, its elastic non-conductive substring is Conventional insulation substring and spring mechanism connects some gold utensils and changes Make and form.
As it is shown in figure 1, this pair of 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 them U-shaped link Be connected to one end of suspension clamp 6 by right-angle hanging ring 4, another U-shaped link connects has EB link plate 1 (also to have 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, and the other end connects spring mechanism 5.Concrete, the two ends of rigid insulation substring 3 are connected to one Individual U-shaped link 2, one of them 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 Receiving one end of spring mechanism 5, the other end of spring mechanism 5 connects EB link plate by a U-shaped link (also has one on EB link plate U-shaped link, for being connected with the U-shaped link of spring mechanism 5).
It addition, the present embodiment also provides for a kind of elastic double string pendency towers, as in figure 2 it is shown, this tower includes tower body 201, this tower Body 201 is provided with at least two cross-arm 202, connects flexible double string part 203 between neighbouring cross-arm 202.Elastic double string The rigid insulator series winding of part 303 connects cross-arm, and elastic insulated substring connects lower cross-arm.Owing to rigid insulation substring hangs over upper horizontal stroke Load, elastic insulated substring is hung on lower cross-arm, therefore uses the steel tower one layer horizontal stroke more than common drape plot tower of elastic double string part Load.
This pendency tower is in the case of calm, and upside rigid insulator provides holding power upwards for wire, and downside is elastic absolutely Edge does not stresses.And under having wind operating mode, wire is by wind action generation sidesway, and insulator is driven to offset.Now upside Rigid insulator will with cross-arm hanging point as axis rotation, and the elastic insulated son in downside except rotate in addition to, spring mechanism occurs simultaneously Elastic deformation, and rotational angle is the biggest, and its deformation is the biggest, and the pulling force provided is the biggest.When drawing of upper and lower both sides insulator When power, wire and insulator wind load, vertical load reach balance, insulator i.e. stops continuing skew.
Spring mechanism uses the cylinder stranded wire helical spring that 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, in high precision table top and requires the vehicle etc. of smooth transport, its Safe and reliable for transmission line of electricity, fatigue and vibrationproof are functional.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, it is noted that all Any amendment, equivalent and the improvement etc. made within the spirit and principles in the present invention, should be included in the guarantor of the present invention Within the scope of protecting.
