Abstract
The utility model discloses a jumper wire over-wind type Z-shaped side slope power transmission line strain tower, and relates to the technical field of high-voltage power transmission lines. The jumper wire over-wind type Z-shaped side slope power transmission line strain tower comprises a tower body, a ground wire frame, an upper side slope guide wire cross arm and a lower side slope guide wire cross arm, wherein the top of the tower body is provided with the ground wire frame; one side of the lower part of the ground wire frame is provided with the upper side slope guide wire cross arm, and the other side of the lower part of the ground wire frame is provided with the lower side slope guide wire cross arm; the upper side slope guide wire cross arm, the tower body and the lower side slope guide wire cross arm form a Z-shaped structure; two sides of the ground wire frame are connected with jumper wire strings respectively. Through the jumper wire over-wind type Z-shaped side slope power transmission line strain tower, the shortcomings of high altitude and low utilization rate of the slope section line towers in the mountainous areas, increase of the overall length of the towers, the corresponding increase of the steel consumption and the basic work amount, great work amount for harvesting forests and poor economy in the local topography-restricted areas are solved.
Description
Technical field:
The utility model relates to ultra-high-tension power transmission line technical field, relate in particular to a kind of adopt on wire jumper around Z-shaped side slope strain tower of transmission line.
Background technology:
Conventional ultra-high-tension power transmission line single loop tension tower conducting wire adopts rounded projections arranged more, and dual-side phase cross-arm is contour, and structural shape is simple, and when along mountain area side slope section cabling, this kind of tower mainly exists following shortcoming:
1) this tower dual-side phase cross-arm height is identical, and during along mountain area side slope section cabling, upper side slope side cross-arm distance to the ground is short compared with slope side cross-arm distance to the ground, in local restricted section, needs to improve shaft tower and exhales the high safe distance requirement over the ground that meets.
2) on this tower, side slope side wire jumper string adopts the conventional mode of connection, and charged some distance to the ground of wire jumper is near, in local restricted section, needs to improve shaft tower and exhales the high safe distance requirement over the ground that meets.Utility model content:
The purpose of this utility model be to provide a kind of adopt on wire jumper around Z-shaped side slope strain tower of transmission line, its adopt on wire jumper around Z-shaped side slope anchor support, meeting under the condition of the stressed and electric clearance of shaft tower, solved that mountain area side slope section overhead line structures exhale that high usage is low, shaft tower overall height increases, the increase corresponding to Foundation Design amount of steel consumption, at local landform confined area, the shortcoming that forest felling engineering quantity is large, economy is poor.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises tower body, earth wire support, upper side slope side wire cross-arm, slope side wire cross-arm, described tower body top is provided with earth wire support, earth wire support below is provided with side slope side wire cross-arm on one side, another side is provided with slope side wire cross-arm, upper side slope side wire cross-arm and tower body, slope side wire cross-arm form " Z " font, and earth wire support both sides are connected with respectively jumper string.
Between tower body earth wire support and slope side wire cross-arm, be provided with middle conducting wire hanging point, middle conducting wire hanging point and on side slope side wire cross-arm, slope side wire cross-arm hitch point place be provided with wire insulation substring.
The utility model is compared with conventional single loop anchor support, has the following advantages:
1) mode that adopts wire oblique arrangement, three-phase conducting wire ladder to arrange, makes full use of the arrangements of conductors advantage parallel with landform, the distance to the ground of side slope opposite side phase conductor and exhale high usage in raising.
2) on upper side slope side phase wire jumper around, improved charged some distance to the ground of wire, in some areas, reduce trees felling.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, a kind of adopt on wire jumper around Z-shaped side slope strain tower of transmission line, it comprises tower body 1, earth wire support 2, upper side slope side wire cross-arm 3, slope side wire cross-arm 4, described tower body top is provided with earth wire support 2, earth wire support below is provided with side slope side wire cross-arm 3 on one side, another side is provided with slope side wire cross-arm 4, upper side slope side wire cross-arm 3 and tower body, slope side wire cross-arm 4 forms " Z " font, earth wire support 2 both sides are connected with respectively jumper string 7, between tower body 1 earth wire support 2 and slope side wire cross-arm 4, be provided with middle conducting wire hanging point 5, middle conducting wire hanging point 5 and on side slope side wire cross-arm 3, slope side wire cross-arm 4 hitch point places are provided with wire insulation substring 6, the utility model is horizontally adjusted into oblique arrangement by dual-side phase conductor, three-phase conducting wire ladder is arranged, upper side slope side cross-arm height is higher than slope side cross-arm, make full use of the arrangements of conductors advantage parallel with landform, the distance to the ground of side slope opposite side phase conductor and exhale high usage in raising, meeting under electric clearance condition simultaneously, by on upper side slope side phase wire jumper around, jumper string hangs on homonymy earth wire support, improved charged some distance to the ground of wire, middle phase conductor also by middle phase jumping wire around, jumper string also hangs on homonymy earth wire support, in some areas, can reduce trees felling, reduce tower material use amount.
The utility model tower adopt on wire jumper around Z-shaped side slope anchor support, meeting under the condition of the stressed and electric clearance of shaft tower, solved that mountain area side slope section overhead line structures exhale that high usage is low, shaft tower overall height increases, the increase corresponding to Foundation Design amount of steel consumption, at local landform confined area, the shortcoming that forest felling engineering quantity is large, economy is poor.
