Description

A kind of coordinated transposition tower
Technical field:
Patent of the present invention is related to ultra-high-tension power transmission line technical field, more particularly to a kind of coordinated transposition tower.
Background technology:
The conventional system scheme cut-off of list back transmission line is at present:Single loop is cut-off to form double-circuit line access one Access and be located therein in the transformer station of a loop line road the same side after transformer station or altogether one section of tower, due to by actual power transformation station location Influence, the double-circuit line formed after cut-offfing need to be accessed in institute's hanging wire road not transformer station of homonymy, and this is accomplished by circuit Coordinated transposition is realized after cut-offfing.
Conventional line coordinated transposition mode after existing single loop cut-offs mainly has following two:
1) the branch of a circuit tower of a base four is used, one side and lower three layers of cross-arm using upper three layers of cross-arm of branch tower Another side, is respectively connected to be located at the circuit of cross-arm not homonymy, realize single back line cut-off after coordinated transposition, but four loop angles Head tower tower head is higher, and can not make full use of all cross-arms of four branch of a circuit towers, there is a situation where to waste tower material, and cross-arm is not Symmetrically, tower resistance to overturning is poor.
2) made using a base single loop anchor support behind another loop line road of a loop line road scissors crossing, access one base double loop point Branch tower, realizes the coordinated transposition after line disconnection, this mode adds the material of a Ji Ta, and floor space is big, does not apply to In the limited area of vertical tower position.
Patent of invention content:
The purpose of patent of the present invention is to propose a kind of coordinated transposition tower, and the new shaft tower can be solved after single back line cut-offs Coordinated transposition problem;Two Ji Ta need not be used again, and tower head is relatively low, tower material consumption is low.
In order to solve problem present in background technology, the technical scheme is that:It includes tower body, and tower body top is set Be equipped with " T " font ground wire cross-arm, be provided with below ground wire cross-arm it is anti-" under " font topping wire cross-arm, it is anti-" under " font upper strata leads Be provided with below line cross-arm " on " layer conductor cross-arm under font, it is described it is anti-" under " font topping wire cross-arm is upper by tower body both sides Lower cross-arm composition on the left of cross-arm and tower body, it is described " on " under font layer conductor cross-arm by the upper cross-arm and tower body two on the right side of tower body The lower cross-arm composition of side.
It is described it is anti-" under " the upper cross-arm of font topping wire cross-arm, lower cross-arm and " on " it is upper on layer conductor cross-arm under font Cross-arm, lower cross-arm end can install wire jumper support and strain insulator-string.
" T " the font ground wire cross-arm is one layer of three side cross-arm structure, wherein while towards breaking point, another both sides perpendicular to Ground wire direction of advance.
Jumper string is hung with below each wire jumper support.
Coordinated transposition tower of the present invention has advantages below:
(1) compared with routinely cut-offfing scheme one, the present invention takes into full account shaft tower stress, using " on " layer conductor is horizontal under font Load and it is anti-" under " font topping wire cross-arm tower head arrangement, rationally utilize wire cross-arm, reduce the use condition of shaft tower, The tower head of reduction about 25% highly, reduces 6 unilateral wire cross-arms, has saved construction investment, cross-arm is more symmetrical, overall structure It is more stable.
(2) compared with routinely cut-offfing scheme two, The present invention reduces the input of a base shaft tower, floor space is reduced, by Vertical tower position influence is small.
(3) design of " T " font ground wire cross-arm, while lightning protection is ensured, it is to avoid ground wire intersects, further It has compressed tower head size.
Brief description of the drawings:
Fig. 1 is structural representation of the invention;
Fig. 2 is Fig. 1 top view;
Fig. 3 is wiring schematic diagram of the invention.
Embodiment:
Reference picture 1-2, a kind of coordinated transposition tower, it includes tower body 1, and the top of tower body 1 is provided with " T " font ground wire cross-arm 4, The lower section of ground wire cross-arm 4 be provided with it is anti-" under " font topping wire cross-arm 2, it is anti-" under " lower section of font topping wire cross-arm 2 is provided with " on " layer conductor cross-arm 3 under font, it is described it is anti-" under " font topping wire cross-arm 2 by the upper cross-arm and tower body of tower body both sides on the left of Lower cross-arm composition, it is described " on " under font layer conductor cross-arm 3 by the upper cross-arm on the right side of tower body and the lower cross-arm group of tower body both sides Into, it is anti-" under " the upper cross-arm of font topping wire cross-arm 2, lower cross-arm and " on " upper cross-arm under font on layer conductor cross-arm 3, under Cross-arm end can install wire jumper support 5 and strain insulator-string, and each lower section of wire jumper support 5 hangs with jumper string 6, " T " font Ground wire cross-arm 4 is one layer of three side cross-arm structure, wherein while towards breaking point, another both sides are perpendicular to ground wire direction of advance.
Reference picture 3, Fig. 3 for the present invention wiring schematic diagram, the present invention using it is anti-" under " on font topping wire cross-arm 2 The access of strain insulator-string 7 right side single back line, forms the left lead of double-circuit line after cut-offfing, utilize " on " layer conductor is horizontal under font The access of strain insulator-string 7 left side single back line in load 3, forms the right side wire of double-circuit line after cut-offfing, and it is double to access next base Loop tower, the left and right sides wire that the present invention is formed after single back line is cut-off is adjusted to opposite side from side, so as to realize two The coordinated transposition of side wire.
The present invention by set by it is anti-" under " the lower cross-arm of font topping wire cross-arm 2 is arranged on the left of tower body, will " on " word The upper cross-arm of layer conductor cross-arm 3 is arranged on the right side of tower body under type, make above and below keep between layer conductor cross-arm enough electric equipment compartment away from, And can install wire jumper support 5 and jumper string 6 additional with reference to being actually needed, it is ensured that both sides wire meets the need of wire and shaft tower electric clearance Will, so under conditions of shaft tower stress and electric clearance is met, leading after single back line cut-offs only is solved by a Ji Ta The coordinated transposition problem of line, reduces tower head size, while reducing the tower material consumption in conventional cross transposition tower, solves The poor shortcoming of economy, it is anti-in addition " under " the upper cross-arm of font topping wire cross-arm and " on " under font under layer conductor cross-arm The equal both sides of cross-arm are symmetrical, and it is anti-" under " the lower cross-arm of font topping wire cross-arm and " on " the upper cross-arm of layer conductor cross-arm under font Position is nearer, smaller to the stability influence of tower body after both active forces to tower body are cancelled out each other so that the overall knot of tower body Structure is more stable.
The present invention is respectively connected to ground wire using the side cross-arm of " T " font ground wire cross-arm 4 three of coordinated transposition tower, wherein towards opening The cross-arm of breakpoint connects the single-circuit inner side ground wire in both sides, and another both sides connect both sides single time respectively perpendicular to the cross-arm of ground wire direction of advance The outside ground wire on road, and the lightning protection of wire is ensured by the length for adjusting " T " font ground wire cross-arm, it is to avoid ground wire intersects, It further have compressed tower head size.
