Abstract

The utility model discloses an F-shaped narrow-base triangular steel tube tower which relates to the technical field of high-voltage transmission lines. The F-shaped narrow-base triangular steel tube tower comprises a tower body, an upper lead cross arm, a middle lead cross arm and a lower lead cross arm, wherein the tower body mainly comprises three steel pipe main materials, the section of the tower is triangular, the upper lead cross arm, the middle lead cross arm and the lower lead cross arm are arranged on the same side of the tower body, and each lead cross arm and the tower body form an F shape. By adopting a narrow base, a triangular tower body section and an F-shaped tower body lead cross arm structure, the F-shaped narrow-base triangular steel tube tower has the advantages of small occupation, light weight, small self restraint stress, small tower body wind load, and land resource conservation, and is capable of greatly increasing the corridor utilization rate.

Description

The narrow base triangle of F shape steel tube tower
Technical field:
The utility model relates to ultra-high-tension power transmission line technical field, relates in particular to the narrow base triangle of a kind of F shape steel tube tower.
Background technology:
Today of electric power fast development, in crowded city or to open up high pressure corridor more and more difficult in outskirts of a town, as high by its cost of cable run, construction and installation, operation expense are high, and how to conflict with municipal piping lane, and conventional Steel Pipe Pole circuit cost being also higher, and high pressure corridor utilization rate, land occupation area is large, wastes a large amount of land resources.
Utility model content:
The utility model provides the narrow base triangle of a kind of F shape steel tube tower, and its adopts cross-arm and tower body to be the vertical arrangement of F shape, and its occupation of land is little, lightweight, self restraint stress is little, tower body wind carries littlely, can greatly improve corridor utilization rate, economizes the land resource.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises tower body, upper conductor cross-arm, middle wire cross-arm, lower wire cross-arm, described tower body is mainly comprised of three main materials of steel pipe, tower body section is triangular in shape, described upper conductor cross-arm, middle wire cross-arm, lower wire cross-arm, be all arranged on the same limit of tower body, each wire cross-arm and tower body form " F " shape.
The hitch point of described upper conductor cross-arm, middle wire cross-arm, lower wire cross-arm is provided with short suspension string.
The utility model is compared and is had following advantage with conventional shaft tower:
(1) triangle tower body section
1) profile succinct, save material, how much constant triangles of tower body section self-assembling formation, a main material, oblique material and a basis have simultaneously been saved, two main materials of steel pipe are arranged in to compression-side, another root steel pipe is at tension side, by case verification, the more conventional steel tube tower of the utility model reduces tower weight 17.3%.
2) steel tower self restraint stress is little, when foundation uneven settlement or variations in temperature, can produce restraint stress, and triangle tower can not produce foundation settlement restraint stress or thermal stresses in quadrangle tower.
3) tower body wind carries littlely, and because triangular section tower body windward side is little, the air resistance coefficient of steel tower is less, and therefore, tower body wind load is corresponding reducing also.
(2) narrow base
Narrow base tower is because root is opened less, can effectively economize the land resource, reduce circuit width of corridor, and processing, transportation, assembling, easy to maintenance, than conventional steel pipe pole saving steel, relatively common steel tower more can be coordinated mutually with civic landscape, uses on the outskirts of a town and the limited overhead transmission line in part corridor, and economic and social benefit is obvious.
(3) F shape cross-arm is arranged
Tower body and cross-arm are F shape and are arranged vertically, the more conventional single loop of circuit removal width of corridor significantly reduces, in City Regions, house, can reduce in a large number removal, effectively reduce construction costs, improve unit corridor transmission capacity, when old track remodelling, can, in conjunction with " reconstruction " and " reusing ", adopt the staggered tower scheme that increases of compliance wedge shape, make cross-arm all point to former central lines of track, realize the matched well with original circuit.
(4) short suspension string
Each wire cross-arm hitch point is provided with short suspension string, does not substantially have the risk of suspension insulator wind pendulum, can effectively dwindle passway for transmitting electricity width of corridor, thereby reduces the flashover jumping electrification risk that circuit produces because of wind pendulum, and reduces tower body height.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing 1, the narrow base triangle of a kind of F shape steel tube tower, it comprises tower body 1, upper conductor cross-arm 2, middle wire cross-arm 3, lower wire cross-arm 4, described tower body 1 is mainly comprised of three main materials of steel pipe, tower body 1 section is triangular in shape, described upper conductor cross-arm 2, middle wire cross-arm 3, lower wire cross-arm 4 is all arranged on the same limit of tower body 1, each wire cross-arm and tower body 1 form " F " shape, the insulator string that each wire cross-arm hitch point is installed is short suspension string 5, because tower body 1 and wire cross-arm are F type vertical arrangement, significantly reduce width of corridor, in City Regions, house, can reduce removal amount, reduce construction costs, improve unit corridor transmission capacity, at special sector, adopt the staggered tower scheme that increases of compliance wedge shape, can realize the matched well with original circuit, other three main materials of tower body make tower body section triangular in shape, two pressurizeds wherein, a tension, not only met stressed requirement but also reduced the quantity of the main material of tower body, save tower weight more than 15%, narrow base tower root is opened little, effectively economize the land resource, reduce circuit width of corridor, and processing, transportation, assembling, easy to maintenance, adopt short suspension string not have the risk of suspension insulator wind pendulum, can effectively dwindle passway for transmitting electricity width of corridor, and then reduce circuit because of the flashover jumping electrification risk of wind pendulum generation, tower body height is corresponding reducing also.
The utility model adopts narrow base, triangle tower body section and F shape tower body wire cross-arm structure, makes that its occupation of land is little, lightweight, self restraint stress is little, tower body wind carries littlely, can greatly improve corridor utilization rate, economizes the land resource.
