The structural representation of a kind of electric wire overhead device that Fig. 1 provides for the embodiment of the present invention;
The structural representation of the another kind of electric wire overhead device that Fig. 2 provides for the embodiment of the present invention.
Detailed description of the invention
Core of the present invention is to provide a kind of electric wire overhead device, ensures the minimum range in the place that street is narrower, to improve safety.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As depicted in figs. 1 and 2, the invention discloses a kind of electric wire overhead device, comprise tower bar 1 and cross-arm 2, wherein, this cross-arm 2 is at least two, and is distributed in tower bar 1 one end in the axial direction and in the side of tower bar 1.The homonymy that cross-arm is positioned at tower bar 1 is arranged so that by above-mentioned, in use, the lateral dimension of this electric wire overhead device can be reduced, thus reduce the horizontal floor space of this electric wire overhead device, thus indirectly increase the lateral separation in narrow street, therefore, this electric wire overhead device can be met to the requirement of minimum range, improve safety.
In specific embodiment, cross-arm 2 being set to two, in order to improve the bonding strength of cross-arm 2, these two cross-arms 2 being connected by connecting rod 4.The double-circuit line that the overhead device of electric wire disclosed in the application adopts.
On the basis of such scheme, the porcelain vase 3 on two cross-arms 2 in the application is arranged in triangular form, and the mode adopting triangular form cabling is conventional mode, and two cross-arms 2 provided in the application, can realize double loop cabling.
For the concrete mode that triangular form is arranged, two upper porcelain vases (being top away from the one end on ground when the top in the application is and normally uses with tower bar 1) will be provided with on the cross-arm 2 at top in the application, on the cross-arm of bottom, be provided with four lower porcelain vases, and each upper porcelain vase and two lower porcelain vases are that isoceles triangle type is arranged.Particularly, the cross-arm 2 near top is shorter than the length of the cross-arm 2 of close bottom.
In addition, in another embodiment cross-arm 2 is set to three, and these three cross-arms 2 are linked together by connecting rod 4, to ensure the intensity of whole electric wire overhead device.Shape and size for connecting rod 4 can be selected according to different needs, and all in protection domain.
By using the mode of three cross-arms 2, realizing two circuit cabling can arrange the porcelain vase 3 on cross-arm 2 in ellipse, and namely all porcelain vases connect into ellipse in turn.
Particularly, on the cross-arm 2 at top, be provided with two the first porcelain vases, on the cross-arm 2 of bottom, be provided with two the 3rd porcelain vases, middle cross-arm 2 is provided with two the second porcelain vases.Wherein in the first porcelain vase, the second porcelain vase and the 3rd porcelain vase all near the line of the porcelain vase of tower bar 1 be arc, line all away from the porcelain vase of tower bar 1 in first porcelain vase, the second porcelain vase and the 3rd porcelain vase is also arc, but the bending direction of these two arcs is contrary, thus form oval structure.
On the basis of technique scheme, in order to improve the intensity of cross-arm 2, the cross-arm 2 near bottom in cross-arm 2 is connected by floor 5 with tower bar 1, particularly, the bottom related in the application be tower bar 1 when normally placing in the one end on the close ground in vertical space, top is the one end away from ground.The bonding strength of tower bar 1 and cross-arm 2 can be improved by arranging floor 5.
