Description
Technical field
The utility model relates to electric power pylon technical field, and a kind of wire is the compound cross-arm tangent tower that inverted triangle is arranged specifically.
Background technology
Current wire is that the straight line pole arranged of equilateral triangle adopts the arrangement of three layers of cross-arm (or support), i.e. two layer conductor cross-arms and one deck earth wire support, as shown in Figure 1, topping wire cross-arm arranges a phase conductor, and lower layer conductor cross-arm arranges two phase conductors.This shaft tower feature is: shaft tower overall height and width of corridor moderate, be applicable to width of corridor less demanding and shaft tower height is had to the region of special restriction.But also there is following shortcoming in it:
1, owing to needing to keep certain electrical safety distance between topping wire cross-arm layout wire and lower layer conductor cross-arm, upper and lower layer conductor cross-arm vertical distance is larger, shaft tower overall height is slightly large, is difficult to meet specific region (as airport) to the requirement of shaft tower height;
2, lower layer conductor cross-arm arranges two phase conductors, combines in equilateral triangle with a phase conductor of topping wire cross-arm, causes over the ground that electromagnetic environment index is poor, therefore needs to raise shaft tower further and exhales height.
How to develop a kind of can reduce shaft tower height and exhale high tangent tower become be badly in need of solve technical problem.
Utility model content
To be that the shaft tower in order to solve prior art cathetus tower is too high cannot meet specific region and use the defect of needs the purpose of this utility model, provides a kind of wire to be that the compound cross-arm tangent tower of inverted triangle layout solves the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of wire is the compound cross-arm tangent tower that inverted triangle is arranged, comprise tower body, the top of tower body is provided with topping wire cross-arm, and the top of topping wire cross-arm is provided with two earth wire supports and two earth wire supports are that mirror image is corresponding, described earth wire support is all provided with ground wire overhanging golden tool string
The both sides that the bottom of described topping wire cross-arm is positioned at tower body are all provided with two V-arrangement suspension insulators, the below described tower body being positioned at topping wire cross-arm is provided with lower floor's compound cross-arm, both sides lower floor's compound cross-arm being positioned at tower body are all provided with overhanging golden tool string, and two the V-arrangement suspension insulators and the overhanging golden tool string three that are positioned at tower body homonymy are del.
The material of described lower floor's compound cross-arm is resin.
The angle of described V-arrangement suspension insulator is 85o-110o.
beneficial effect
A kind of wire of the present utility model is the compound cross-arm tangent tower that inverted triangle is arranged, compared with prior art have compressed levels wire cross-arm vertical distance, shorten lower wire suspension string length, reduce shaft tower overall height, decrease comprehensive cost, improve electromagnetic environment index over the ground.Because lower layer conductor cross-arm is compound cross-arm (insulation materials), topping wire cross-arm is arranged and is not substantially considered electric clearance requirement between wire and lower layer conductor cross-arm, thus have compressed tower head size further; The wire suspension string of compound cross-arm is only hardware string simultaneously, naked, and suspension string length significantly reduces, and reduces shaft tower and exhales height.Due to three-phase conducting wire be del arrange, two phase conductors upper, a phase conductor under, electromagnetic environment index is more excellent over the ground, improves electromagnetic environment index over the ground.

Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present utility model and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in Figure 2, a kind of wire described in the utility model is the compound cross-arm tangent tower that inverted triangle is arranged, comprises tower body 1, tower body 1 adopts two-layer cross-arm design, for hanging two three-phase conducting wires.The upper end of tower body 1 is provided with topping wire cross-arm 3, and it is that mirror image is corresponding that the top of topping wire cross-arm 3 is provided with the both sides that two earth wire supports, 2, two earth wire supports 2 are positioned at tower body 1.Earth wire support 2 is all provided with ground wire overhanging golden tool string 5, for arranging that ground wire uses.The both sides that the bottom of topping wire cross-arm 3 is positioned at tower body 1 are all provided with two V-arrangement suspension insulators 6, and two V-arrangement suspension insulators 6 of tower body 1 homonymy are for arranging that two phase conductors use.The quantity of V-arrangement suspension insulator 6 is total up to four, the angle of V-arrangement suspension insulator 6 can be 85o-110o, be distributed in the both sides of tower body 1 respectively between two, namely the bottom of topping wire cross-arm 3 is positioned on the left of tower body 1 and is provided with two V-arrangement suspension insulators 6, and the bottom of topping wire cross-arm 3 is positioned on the right side of tower body 1 and is provided with two V-arrangement suspension insulators 6 equally.
Below tower body 1 being positioned at topping wire cross-arm 3 is provided with lower floor's compound cross-arm 4, and lower floor's compound cross-arm 4 is arranged on tower body 1, and is positioned at the below of topping wire cross-arm 3, jointly forms the design of two-layer cross-arm with topping wire cross-arm 3.Lower floor's compound cross-arm 4 is insulation materials characteristic, and its material is resin.Because lower floor's compound cross-arm 4 is insulation materials, the vertical distance between itself and topping wire cross-arm 3 can be compressed further, thus reduces tower head size, reduces shaft tower overall height, meets the requirement of specific region to shaft tower height.Both sides lower floor's compound cross-arm 4 being positioned at tower body 1 are all provided with overhanging golden tool string 7, and overhanging golden tool string 7 is directly installed on lower floor's compound cross-arm 4.Because lower floor's compound cross-arm 4 is the characteristic of insulation materials, it can directly install overhanging golden tool string 7 without the need to insulator, thus significantly reduces suspension string length, reduces shaft tower and exhales height.Equally, because lower floor is the design of compound cross-arm, decrease shaft tower steel material and lower phase insulator, reduce comprehensive cost.There is an overhanging golden tool string 7 in the left side being positioned at tower body 1, and the right side being positioned at tower body 1 has an overhanging golden tool string 7 equally, and overhanging golden tool string 7 is for arranging a phase conductor.Be positioned at tower body 1 homonymy (left side or right side) and there is two V-arrangement suspension insulators 6 and an overhanging golden tool string 7 respectively, this three is del, namely because two V-arrangement suspension insulators 6 and an overhanging golden tool string 7 hang wire respectively, three-phase conducting wire, together in del, forms wire del and arranges.Its two phase conductor upper, a phase conductor under, electromagnetic environment index is more excellent over the ground, can meet the strict demand of specific region to electromagnetic environment index.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and manual; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
