Description
Technical field
This utility model relates to a kind of wire rounded projections arranged two circuit tower, belongs to ultra-high-tension power transmission line technical field.
Background technology
Along with national economy development, the rapid expansion of city size, establish the quantity of ultra-high-tension power transmission line also not
Disconnected increase, the external environmental factor that engineering construction relates to is the most complicated.Complicated for some regions, the situation that passage is short, for
Smooth cabling, typically uses the cabling mode taken a devious route at present, or use the mode of high steel tower to carry out cabling, no matter which kind of
The problems such as mode, all exists circuit floor space big, and construction costs is high.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of wire rounded projections arranged two circuit tower, its structure letter
Single, more conventional steel tower is low, in the case of ensureing safety, can realize the cabling in short space, can overcome prior art not
Foot.
The technical solution of the utility model is: a kind of wire rounded projections arranged two circuit tower, including tower body, interior angle side loop
Wire and exterior angle side loop wire, be sequentially installed with interior angle side ground wire cross-arm, interior angle from top to bottom in the interior angle side of described tower body
On side, lower phase cross-arm in phase cross-arm, interior angle side, is sequentially installed with side, exterior angle ground wire from top to bottom horizontal in the side, exterior angle of described tower body
Lower phase cross-arm in phase cross-arm, side, exterior angle on load, side, exterior angle；Described interior angle side loop wire includes on interior angle side ground wire, interior angle side
Phase conductor under phase conductor and interior angle side in phase conductor, interior angle side, is sequentially arranged at interior angle side ground wire by interior angle side strain insulator-string horizontal
On load, interior angle side, in phase cross-arm, interior angle side, in the lower outer end of phase cross-arm, interior angle side the inside of lower phase cross-arm；Side, described exterior angle is returned
Line conductor includes on side, exterior angle ground wire, side, exterior angle in phase conductor, side, exterior angle phase conductor under phase conductor and side, exterior angle, by side, exterior angle
Strain insulator-string is sequentially arranged on side, exterior angle ground wire cross-arm, side, exterior angle to descend in the inside of phase cross-arm, side, exterior angle in phase cross-arm, side, exterior angle
The outer end of lower phase cross-arm.
Described interior angle side loop wire is parallel with exterior angle side loop wire, and is deviated to the right 30 degree the most in the horizontal direction.
So interior angle side loop wire can be gradually distance from tower body, and exterior angle side loop wire can move closer to tower body, is ensureing circuit peace
Entirely, do not discharge, leak electricity in the case of, can effectively take into account the manufacturing cost of steel tower.
Ground wire cross-arm phase cross-arm length lower with side, exterior angle in side, described exterior angle is equal.
Ground wire cross-arm phase cross-arm length lower with interior angle side in described interior angle side is equal.
The beneficial effects of the utility model are: this utility model by by lower phase conductor be installed in same cross-arm
On, compared with existing four cross-arm steel towers, not only can effectively reduce the height of steel tower, and steel tower system can be effectively reduced
Cause this.This utility model simple in construction, in the case of ensureing safety, can realize the cabling in short space.This utility model
It is particularly suitable for the conveying electricity in short space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and utility model is described further by specific embodiment: this utility model wire triangle
Shape arrangement two circuit tower, including tower body 1, interior angle side loop wire and exterior angle side loop wire, in the interior angle side of described tower body from
It is sequentially installed with down on interior angle side ground wire cross-arm 2, interior angle side and phase cross-arm 3, interior angle side are descended phase cross-arm 4, at described tower body 1
Side, exterior angle be sequentially installed with on side, exterior angle ground wire cross-arm 5, side, exterior angle in phase cross-arm 6, side, exterior angle lower phase cross-arm 7 from top to bottom；
Described interior angle side loop wire includes that on interior angle side ground wire, interior angle side, in phase conductor, interior angle side, phase conductor is led under interior angle side mutually
Line, is sequentially arranged on interior angle side ground wire cross-arm 2, interior angle side by interior angle side strain insulator-string and descends phase cross-arm in phase cross-arm 3, interior angle side
The inside of lower phase cross-arm 4 in the outer end of 4, interior angle side；Described exterior angle side loop wire includes that side, exterior angle ground wire, exterior angle are led on side mutually
Phase conductor under phase conductor and side, exterior angle in line, side, exterior angle, by side, exterior angle strain insulator-string be sequentially arranged at side, exterior angle ground wire cross-arm 5,
