Description

Double back becomes single time angle steel tower

Technical field

The utility model relates to ultra-high-tension power transmission line technical field, and particularly a kind of double back becomes single time angle steel tower.

Background technology

In power grid construction, sometimes need that a list is returned overhead wire and cut-off, π enters a newly-built transformer station respectively, to share electric load, optimizes mains supply system.

Wire is become to the transmission line of electricity of triangle arrangement, when carrying out π and connecing, existing scheme needs to transform the shaft tower of former circuit, and after changing triangle arrangement into vertical arrangement, then carry out π and connect, thus cause power off time long, cost is high.

Utility model content

The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, and the utility model provides a kind of double back to become single time angle steel tower.

The utility model solves the technical scheme that its technical problem adopts: a kind of double back becomes single time angle steel tower, comprise tower body, described tower body top is provided with ground wire cross-arm, described ground wire cross-arm is bilateral cross-arm, five groups of wire cross-arms are provided with below described ground wire cross-arm, bottom line cross-arm is all vertical with tower body with wire cross-arm, described five groups of wire cross-arms are followed successively by A group wire cross-arm from top to bottom, B group wire cross-arm, C group wire cross-arm, D group wire cross-arm and E group wire cross-arm, described B group wire cross-arm, C group wire cross-arm is all parallel with ground wire cross-arm with E group wire cross-arm, described A group wire cross-arm is all vertical with ground wire cross-arm with D group cross-arm.

Spacing between described B group wire cross-arm and ground wire cross-arm is 5 meters, and described C group wire cross-arm and the spacing between E group wire cross-arm and D group wire cross-arm are 3.5 meters.

The length of described C group wire cross-arm is greater than the length of A group wire cross-arm, B group wire cross-arm, D group wire cross-arm, E group wire cross-arm and ground wire cross-arm, and namely the length of C group wire cross-arm is the longest.

The beneficial effects of the utility model are, adopt double back of the present utility model to become single time angle steel tower, wire are become to the transmission line of electricity of triangle arrangement, can directly carry out π and connect, easy construction, save power off time, cheap.

Detailed description of the invention

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As Figure 1-3, a kind of double back of the present utility model becomes single time angle steel tower 10, comprise tower body 1, described tower body 1 top is provided with ground wire cross-arm 2, described ground wire cross-arm 2 is bilateral cross-arm, five groups of wire cross-arms are provided with below described ground wire cross-arm 2, bottom line cross-arm and wire cross-arm are all vertical with tower body 1, described five groups of wire cross-arms are followed successively by A group wire cross-arm 3 from top to bottom, B group wire cross-arm 4, C group wire cross-arm 5, D group wire cross-arm 6 and E group wire cross-arm 7, described B group wire cross-arm 4, C group wire cross-arm 5 is all parallel with ground wire cross-arm 2 with E group wire cross-arm 7, described A group wire cross-arm 3 is all vertical with ground wire cross-arm 2 with D group cross-arm.

Spacing between described B group wire cross-arm 4 and ground wire cross-arm 2 is 5 meters, and described C group wire cross-arm 5 and the spacing between E group wire cross-arm 7 and D group wire cross-arm 6 are 3.5 meters.

The length of described C group wire cross-arm 5 is greater than the length of A group wire cross-arm 3, B group wire cross-arm 4, D group wire cross-arm 6, E group wire cross-arm 7 and ground wire cross-arm 2, and namely the length of C group wire cross-arm 5 is the longest.

Primitive nail transformer station 100 returns overhead wire to the list of second transformer station 200 and cut-offs, and is connected to the third transformer station 300 respectively, to form first third, second the third two new line channels.Angle steel tower 10 of the present utility model is arranged at the wire center position of primitive nail second circuit.After single time overhead wire three-phase conducting wire is connected to D group wire cross-arm 6 and A group wire cross-arm 3 respectively, the mode connected by wire jumper is connected to B group wire cross-arm 4, C group wire cross-arm 5 and E group wire cross-arm 7.

With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
