Abstract

The utility model discloses a 220-kilovolt all-angle single-circuit drilling cross tower. The 220-kilovolt all-angle single-circuit drilling cross tower comprises a tower body and a straight arm connected with the tower body, wherein a ground wire cross arm is arranged at the top end of the straight arm, an upper wire cross arm is fixed under the ground wire cross arm, a lower wire cross arm is fixed under the upper wire cross arm, overhanging strings are connected between the ground wire cross arm and the lower wire cross arm, and wire hanging points of the overhanging strings are connected with the upper wire cross arm. On the premise of meeting the requirement of electric clearance, lightning protection and other respects, the height of a tower head is compressed to the greatest extent, and therefore drilling cross points are easy to choose, a wire route is optimized, and construction cost is lowered.

Description

The 220kv kilovolt full-angle single circuit drilling tower
Technical field
The utility model relates to the steel tower that erects power transmission lines, and is specially a kind of 220kv kilovolt full-angle single circuit drilling tower.
Background technology
At present, newly-built 220kv circuit is mostly with common-tower double-return Lu Weizhu, this steel tower comprises body of the tower, straight-arm and cross-arm, and the both sides, front and back of every layer of cross arm end bottom surface all are provided with the traction insulator string of traction wire, and wire is to arrange with the overhang of wire self below cross-arm.Because the wire of this steel tower is vertical arrangement, the tower head height of steel tower is higher, thus be difficult to select to bore more point, and also the technical scheme complexity that operates, difficulty of construction are large, sometimes may need to stop work, and have affected normal operation, so that construction cost is high.
The utility model content
The technical problem that the utility model solves is to provide a kind of 220kv kilovolt full-angle single circuit drilling tower, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The 220kv kilovolt full-angle single circuit drilling tower, comprise body of the tower, be connected in the straight-arm of body of the tower, the top of described straight-arm is provided with the ground wire cross-arm, the upper conductor cross-arm be fixed on described ground wire cross-arm below, be fixed with the lower wire cross-arm below the described upper conductor cross-arm, be connected with suspension string between described ground wire cross-arm and the lower wire cross-arm, the hanging wire point of described suspension string links to each other with described upper conductor cross-arm.
In the utility model, the end of described lower wire cross-arm links to each other with described ground wire cross-arm by insulator string.
Beneficial effect
The utility model compresses the tower head height as far as possible under the prerequisite that satisfies the aspects requirements such as electric clearance, lightning protection, more point is very easy so select to bore, and has optimized thus line route, has reduced construction costs.
Description of drawings
Fig. 1 is the structure chart of 220kv kilovolt full-angle single circuit drilling tower.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the structure chart of 220kv kilovolt full-angle single circuit drilling tower, the 220kv kilovolt full-angle single circuit drilling tower, comprise body of the tower 1, be connected in the straight-arm 4 of body of the tower, the top of described straight-arm 4 is provided with ground wire cross-arm 5, upper conductor cross-arm 6 be fixed on described ground wire cross-arm 5 below, be fixed with horizontal 7 loads of lower wire below the described upper conductor cross-arm 6, be connected with suspension string 3 between described ground wire cross-arm 5 and the lower wire cross-arm 7, the hanging wire point of described suspension string 3 links to each other with described upper conductor cross-arm 6.
In the utility model, the end of described lower wire cross-arm 7 links to each other with described ground wire cross-arm 5 by insulator string 2.
More than show and described basic principle of the present utility model and 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; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
