Specific implementation mode
According to requiring, the specific implementation mode of the present invention will be disclosed here.It is to be understood, however, that described herein
Embodiment be only the present invention exemplary, can be presented as various forms.Therefore, what is disclosed here is specific thin
Section is not to be considered as limiting, and is merely possible to the basis of claim and as instructing those skilled in the art
By in practice it is any it is appropriate in a manner of differently apply the representative basis of the present invention, include using described herein various
Feature simultaneously combines the feature that may do not disclose clearly here.
Embodiment one：
It includes that tower body 5 and setting exist that Fig. 2, which show the angle tower 110 at circuit corner and uses schematic diagram, angle tower 110,
The conducting wire 7 of cross-arm 6 on tower body 5, corner is articulated in respectively on cross-arm 6.In the present embodiment, 7 crank degree of conducting wire is 120 °.
In the present embodiment, cross-arm 6 is the compound cross-arm of V-type, and the open end of V-shape connects tower body 5, and apex is freely
End is used for connecting wire 7.Cross-arm 6 include two cross arm insulators 8 and free end, two cross arm insulators 8 freely bring out it is logical
Cross the fixation of end metal fitting 9.
The partial enlarged view of cross-arm free end as shown in figure 3, cross-arm free end include end metal fitting 9, extension device 10 and
Bridle wire apparatus 11.Specifically, extension device 10, one end connecting pin of each extension device 10 is respectively set in the both sides of end metal fitting 9
The conducting wire 7 of portion's gold utensil 9, the other end and homonymy connects.Bridle wire apparatus 11 is fixed on end metal fitting 9, is used to support wire jumper.
In the present embodiment, conducting wire 7 and the angle of 6 center line of cross-arm are 60 °, and extension device 10 is horizontally set on free end, and
Extension device 10 and the angle of 6 center line of cross-arm are 90 °.The setting of extension device 10, which is equivalent to, extends 5 homonymy of tower body, two corner conducting wire 7
Virtual point of intersection, therefore distance of the conducting wire 7 apart from tower body increases, and conducting wire 7 can be met in the case where not changing 6 length of cross-arm
With the electric clearance between tower body 5.
For the ease of intuitively illustrating, Fig. 2 and Fig. 1 can be compared, Fig. 1 is the angle tower 100 that extension device is not arranged, and Fig. 2 is
The angle tower 110 of extension device 10 is provided in the present embodiment, the two crank degree is identical, and cross-arm length is identical, conducting wire 7 in Fig. 2
To tower body 5 distance L2 be more than Fig. 1 in conducting wire 3 arrive tower body distance L1.
Or using any point on end metal fitting 9 as starting point, the parallel lines of conducting wire 7 are drawn, it is evident that drawn flat
The distance of line to tower body 5 is less than the distance that conducting wire 7 arrives tower body 5, i.e., the cross-arm for being provided with extension device 10 is used on angle tower
The electric clearance between conducting wire and tower body is more easily satisfied.
In the present embodiment, extension device 10 is to be horizontally set on free end, therefore can directly use in extension device 10 and cross-arm 6
Wire clamp angle is made comparisons, it is apparent that extension device can not also be fully located in horizontal plane, extension device can deviate one in vertical plane
Angle, as long as in the projection of horizontal plane, extension device is more than the angle of homonymy conducting wire and cross-arm center line with the angle of cross-arm center line
.
In addition, being additionally provided with two reinforcements in the free end of cross-arm 6, this two reinforcements includes oblique part 12 and auxiliary
Part 13, oblique part 12 form a V-structure with extension device 10, i.e., the end of oblique part 12 and extension device 10 is fixed on a company
V-shaped vertex is formed on fishplate bar 14, the other end of oblique part 12 is fixed on end metal fitting 9.The setting of oblique part 12 increases
The rigidity and intensity of extension device 10.Auxiliary member 13 connects oblique part 12 and extension device 10, further strengthens oblique part 12 and prolongs
The V-shape structure that long part 10 is formed, that is, further increase the rigidity and intensity of extension device 10.
Due to the use of extension device 10, avoid that cross-arm 6 is long, so the angle tower for being provided with cross-arm 6 is avoided that and leads
The ungratified situation of electric clearance between line, and light weight, line corridor are narrow.
The quantity of corner conducting wire is not the inventive point of the present invention, so corner conducting wire can also be split conductor.In this reality
It applies in example, 110 outer corner of angle tower is provided with extension device 10, naturally it is also possible to which in inside lock, extension device 10 is set.Due to outside
Corner, the conducting wire of corner is first close to further away from tower body, and in interior corner, the conducting wire of corner is directly away from tower body, so relatively
In inside lock, outer corner is with greater need for setting extension device.
Embodiment two：
As shown in Figure 4 and Figure 5, in the present embodiment, extension device 15 is fixed on as a whole on end metal fitting 16, is turned
Angle conducting wire 17 is connected to the both ends of extension device 15.Different from embodiment one, the extension device 15 of the present embodiment is by five segment length
Uneven holder 18 is formed by connecting.It can select the bracket assembled of respective numbers at the extension device of required length as needed, meet
Electric clearance between conducting wire and tower body.In addition, when extension device needs longer, the form using multistage bracket assembled is cleverer
It is living.In this implementation, reinforcer and auxiliary member are also provided in the free end of cross-arm, effect and structure and phase in embodiment one
Together, details are not described herein.
Embodiment three：
Cross-arm structure, material and the conducting wire that the extension device of the present invention is not intended to limit its application deliver angle etc..Such as Fig. 6 institutes
Show, in the present embodiment, the cross-arm 19 on angle tower 120 is "-" type cross-arm, and it is 100 ° that conducting wire 20, which delivers angle, and corner is led
Line 20 and 19 center line angle of cross-arm are 50 °.In the present embodiment, inside and outside corner is both provided with extension device.
Specifically, cross-arm 19 includes cross arm insulator 21 and the free end far from tower body 22, and free end includes end metal fitting
23 and the extension device 24 that is connect with end metal fitting 23.Extension device 24 is a rectangular slab, and the inclination angle in vertical plane is
60 °, and two angles between 19 center line of cross-arm are respectively 70 ° and 110 °.Due between 19 center line of extension device 24 and cross-arm
Any one angle is both greater than conducting wire 20 and 19 center line angle of cross-arm, thus the cross-arm 19 in the present embodiment can meet conducting wire 20 with
Electric clearance between tower body 22.
In the present embodiment, 23 one end of end metal fitting is sleeve, is glued with cross arm insulator 21；One end is connecting plate, with
Extension device 24 is fixed.End metal fitting is not the inventive point of the present invention, as long as end metal fitting satisfaction can be fixed with extension device.
In addition the connection type of extension device and conducting wire nor invention inventive point, be generally in the art mounted by wire clamp, as long as
It can realize that conducting wire is connect with extension device.
The technology contents and technical characterstic of the present invention have revealed that as above, it being understood, however, that in the creative ideas of the present invention
Under, those skilled in the art can make various changes and improve to above structure and material, including individually discloses or want here
Ask the combination of the technical characteristic of protection, it will be apparent that other combinations including these features.These deformations and/or combination each fall within this
In the involved technical field of invention, and fall into the protection domain of the claims in the present invention.
