Description

A kind of ultra-high-tension power transmission line steel tube tower terminal
Technical field
The utility model relates to a kind of power equipment, particularly a kind of steel tube tower.
Background technology
Along with Chinese society rapid development of economy, electricity need load progressively increases, and ultra-high-tension power transmission line enters city becomes development trend.Steel pipe pole has that structure is simple, intensity is high, handsome in appearance, the process-cycle is short, floor space is few, transport and the advantage such as to save time easy for installation, be applicable to the poles such as the different voltages of multiloop joint use, develop with modern city and coordinate mutually, be widely used in the construction of 10-220kv transmission line of electricity.But because the cross-arm that steel pipe pole is arranged directly is connected by welding manner with mobile jib, make troubles, and cross-arm generally adopts pipe to the installation of cross-arm, its application life is not long.
Utility model content
The purpose of this utility model is to provide a kind of ultra-high-tension power transmission line steel tube tower terminal, and its structural stability is better, longer service life, and reliably easier for installation.
The purpose of this utility model is achieved in that a kind of ultra-high-tension power transmission line steel tube tower terminal, comprise the mobile jib fixed on the ground by flange in the bottom, described mobile jib is formed by Flange joint by the above conical hollow bar of two joints, described mobile jib is from top to bottom provided with ground connection cross-arm successively in pairs, first cross-arm, second cross-arm and the 3rd cross-arm, between first cross arm end and the second cross arm end, all be connected through the cable set that insulate between second cross arm end with the 3rd cross arm end, described insulation cable group is made up of two insulators and a connection cable, the middle part of described second cross-arm and the 3rd cross-arm is provided with transition bracket, described transition bracket is provided with spool, the end of described spool connects switching insulator, the other end of switching insulator is connected with respective top connection cable through transition wire cable.
Compared with prior art, the beneficial effects of the utility model are, in the utility model, mobile jib is segmentation structure, handling ease, and easy construction is safe and reliable to operation, reduce labour intensity, safeguard that work amount is few; The features such as segmentation mobile jib is connected by abutted flange, and stable connection is not yielding, can bear larger load, easy to use; Cable enters spool by insulator, enters in the circuit of underground recently, and this structure makes the transmission of electric energy, and safe ready is reliable more.The utility model can be used in power system.
Mutually disturb between cable, improve the safety of delivery of electrical energy, described mobile jib is also provided with multiple guiding trestle, and described spool is arranged on guiding trestle.
In order to avoid mutually disturbing between cable further, described guiding trestle is arranged on side perpendicular with cross-arm installed surface on mobile jib.
In order to make maintenance convenient, the another side of mobile jib being installed guiding trestle is provided with cat ladder.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is mobile jib in the utility model, cross-arm, cat ladder, guiding trestle arrangement schematic diagram.
Wherein, 1 ground connection cross-arm, 2 first cross-arms, 3 insulators, 4 switching insulators, 5 second cross-arms, 6 spools, 7 transition cables, 8 connection cables, 9 the 3rd cross-arms, 10 guiding trestles, 11 mobile jibs, 12 cat ladders.
Detailed description of the invention
A kind of ultra-high-tension power transmission line steel tube tower terminal as shown in Figure 1-2, comprise the mobile jib 11 fixed on the ground by flange in the bottom, mobile jib 11 is formed by Flange joint by the above conical hollow bar of two joints, mobile jib 11 is from top to bottom provided with ground connection cross-arm 1 successively in pairs, first cross-arm 2, second cross-arm 5 and the 3rd cross-arm 9, between first cross-arm 2 end and the second cross-arm 5 end, all be connected through the cable set that insulate between second cross-arm 5 end with the 3rd cross-arm 9 end, insulation cable group is made up of two insulators 3 and a connection cable 8, the middle part of the second cross-arm 5 and the 3rd cross-arm 9 is provided with transition bracket 13, transition bracket 7 is provided with spool 6, the end of spool 6 connects switching insulator 4, the other end of switching insulator 4 is connected with respective top connection cable 8 through transition wire cable 7, mobile jib 11 is also provided with multiple guiding trestle 10, spool 6 is arranged on guiding trestle 10, guiding trestle 10 is arranged on side perpendicular with cross-arm installed surface on mobile jib 11, the another side of mobile jib 11 being installed guiding trestle 10 is provided with cat ladder 12.
In the utility model, mobile jib 11 is segmentation structure, handling ease, and easy construction is safe and reliable to operation, reduces labour intensity, safeguards that work amount is few; The features such as segmentation mobile jib 11 is connected by abutted flange, and stable connection is not yielding, can bear larger load, easy to use; Cable enters spool 6 by insulator 3, enters in the circuit of underground recently, and this structure makes the transmission of electric energy, and safe ready is reliable more.
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
