Abstract

The invention relates to the technical field of high-tension transmission lines, in particular to a novel V-combination serial type transmission line tower comprising a tower body. V-combination strings are hung on cross arms of the tower body, wire jumper brackets are additionally mounted on heads of each cross arm, a wire jumper string is hung under each wire jumper bracket, the V-combination strings are butted via two strain insulator strings horizontally arranged along the line direction, and a V-shaped link fitting is connected at the butt joint of the two strain insulator strings in the direction perpendicular to the line. Width of the tower head is reduced effectively, weight of the tower is reduced, occupation on line corridors is reduced, and elevation utilization rate of the tower is increased.

Description

A kind of Novel power transmission overhead line structures that adopt V-type combination serial type

Technical field:

The present invention relates to ultra-high-tension power transmission line technical field, relate in particular to a kind of Novel power transmission overhead line structures that adopt V-type combination serial type.

Background technology:

For the comparatively nervous section in corridor, path, conventional I string drum type is arranged double loop tangent tower and drum type 3V string double loop tangent tower, because of its tower head width larger, in the time running into compare Zhai location, corridor, need to be by falling trees in a large number, the mode in dismounting house etc., widen width of corridor, at present domestic for this problem, some novel shaft towers have been proposed, comprise 3I string split tower, 3V string split tower and three layers of cross-arm compact type tower etc., these novel shaft towers can compress the tower head width of shaft tower, but often increase in a large number shaft tower tower weight, improve the project cost of shaft tower, therefore, consider that existing shaft tower exists the shortcoming that the compression of tower head width is limited or shaft tower weight increases, be necessary to propose that one can effectively be compressed circuit corridor and tower weight changes unconspicuous insulator string form.

Summary of the invention:

The object of this invention is to provide a kind of Novel power transmission overhead line structures that adopt V-type combination serial type, this shaft tower is by reasonable Arrangement tower head, and the effective and reasonable V-type combination string that utilizes, has reduced taking of corridor, has avoided increasing the shortcoming of shaft tower weight.

In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises tower body, on tower body cross-arm, be hung with V-type combination string, add wire jumper support at cross-arm head, wire jumper support below is hung with jumper string, described V-type combination string is docked by two strain insulator-strings along line direction horizontal arrangement, is connected with and adopts V-type to connect gold utensil in two strain insulator-string joint horizontal path directions simultaneously.

The present invention has effectively compressed tower head width, has reduced shaft tower weight, has reduced circuit corridor and has taken, and has improved shaft tower and has exhaled high usage.

Brief description of the drawings:

Fig. 1 is the structural representation of invention;

Fig. 2 is the structural representation of V-type combination string;

Fig. 3 is the left view that in Fig. 2, V-type connects gold utensil.

Embodiment:

With reference to Fig. 1-3, a kind of Novel power transmission overhead line structures that adopt V-type combination serial type, it comprises tower body 1, on tower body 1 cross-arm, be hung with V-type combination string 2, add wire jumper support 3 at cross-arm head, wire jumper support 3 belows are hung with jumper string 4, described V-type combination string 2 is docked by two strain insulator-strings 5 along line direction horizontal arrangement, in two strain insulator-strings, 5 joint horizontal path directions, adopt V-type to connect gold utensil 6 and connect strain insulator-string 5 and cross-arm simultaneously, it is that the yoke plate 7 being equipped with by lower end is connected with strain insulator-string 5 joints that described V-type connects gold utensil 6, owing to adopting strain insulator-string, so just can realize near tower body without live components, between circuit and tower body, distance is no longer subject to clearance distance control, only need meet under strong wind operating mode strain insulator-string and tower body contactless, and V-type connects gold utensil and no longer needs to install insulator, adopting in addition V-type to connect gold utensil can control circuit windage yaw amount, further reduce wire spaced apart, reduce conducting wire hanging point to ground level, because using strain insulator-string need to adopt wire jumper conducting, as adopt conventional wire jumper, wire jumper is positioned at strain insulator-string below, wire jumper is originally as electrified body, for meeting the electric clearance of wire and tower body, hitch point position is subject to wire jumper clearance control, and the present invention is by increasing wire jumper support, the jumper string that adopts wire jumper support below to hang makes wire jumper realize wire conducting function and meet electric clearance requirement away from tower body, in the case of not changing the mechanical characteristic of insulator string, shaft tower compared with conventional needle to corridor compression, effectively reduce tower head width, reduce shaft tower weight, reducing circuit corridor takies.
