Description

Do the font strained angled tower with tower three back transmission lines
Technical field
The utility model relates to a kind of overhead transmission line iron tower, in particular, relate to a kind of same tower three back transmission line strained angled towers of dried font.
Background technology
The development of China's electric utility is at present advanced by leaps and bounds, and super-pressure, big capacity, multiloop are carried the inexorable trend that has become the electric power conveying, but ultra-high-tension power transmission line causes various contradictions more and more outstanding owing to taking too much, the wide problem in corridor.High pressure and extra high voltage network adopt the situation of multi-circuits transmission lines on single tower to be obvious ascendant trend in recent years.
Existing super-pressure with tower multiloop transmission line of electricity mainly based on the double loop, growing tension along with circuit corridor resource, also begin to apply to engineering design with tower four loops, their common feature is that feeder number is even number, left and right symmetrically is distributed in the body of the tower both sides, has greatly reduced the circuit corridor.
At the situation of 3 times supertension lines under needing to arrange in same corridor, the general practice is the scheme that adopts a common-tower double-return Lu Jiayi single loop parallel at present, needs to take very wide circuit corridor for this reason.If a common-tower double-return road and a single loop are made up on same iron tower, form one with tower three loops, will solve transmission line of electricity effectively and take too much, the wide problem in corridor.The utility model will be to studying with tower three loops series iron tower, and develop a kind of with tower three back transmission line strain insulator corner iron towers.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of same tower three back transmission lines that take up room of optimizing to do the font strained angled tower.
The purpose of this utility model is finished by following technical solution, and it mainly comprises tower leg 4, body of the tower 5, tower head and ground wire upper frame 7.Described tower head is up and down by single loop tower head 10 and double loop tower head 9 and rearranges, double loop tower head 9 places the lower end, wherein said single loop tower head 10 by about two limit phase conductor cross-arms 1 and the lead hanger 8 that is positioned at the tower head neck constitute, in single loop tower head 10 upper ends shared ground line bracket 7 is installed.
Described double loop tower head 9 is arranged vertically by three layer conductor cross-arms and constitutes, from fall down to be followed successively by upper conductor cross-arm 2, lead cross-arm 3 and lower wire cross-arm 6; Wherein six phase conductors are the drum type layout, and middle phase conductor cross-arm 3 slightly is longer than the lower wire cross-arm.
The single loop tower head 10 that is triangularly arranged and is constituted by three-phase conducting wire is being arranged on the top of described double loop tower head, and the limit phase conductor cross-arm 1 of this single loop tower head 10 is positioned at the middle part, and middle phase conductor cross-arm is positioned at leg-of-mutton top, and directly is hung on body of the tower.
The utility model is from iron tower structural configuration and stressed angle with rational, to having carried out economic technology with the multiple structure scheme of tower three back transmission line iron towers relatively, propose a kind of single loop last, double loop under " pyramid " formula layout.Compared with prior art, the beneficial effects of the utility model are: reduced the tower head size, thereby reduced circuit width of corridor, reduction tower material consumption effectively, improved the transmission power of unit corridor.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Label shown in Fig. 1 plants is: phase cross-arm, 9 double loop tower heads, 10 single loop tower heads in phase conductor cross-arm, 7 ground wire upper frames, the 8 single loops part under phase conductor cross-arm, 4 tower legs, 5 bodies of the tower, the 6 double loop parts in phase conductor cross-arm, the 3 double loop parts on 1 single loop part limit phase cross-arm, the 2 double loop parts.
The utility model is described in further detail below in conjunction with accompanying drawing.Shown in the accompanying drawing 1, the utility model mainly comprises tower leg 4, body of the tower 5, tower head and ground wire upper frame 7.Described tower head is up and down by single loop tower head 10 and double loop tower head 9 and rearranges, double loop tower head 9 places the lower end, wherein said single loop tower head 10 by about two limit phase conductor cross-arms 1 and the lead hanger 8 that is positioned at the tower head neck constitute, in single loop tower head 10 upper ends shared ground line bracket 7 is installed.
Described double loop tower head 9 is arranged vertically by three layer conductor cross-arms and constitutes, from fall down to be followed successively by upper conductor cross-arm 2, lead cross-arm 3 and lower wire cross-arm 6; Wherein six phase conductors are the drum type layout, and middle phase conductor cross-arm 3 slightly is longer than the lower wire cross-arm.
The single loop tower head 10 that is triangularly arranged and is constituted by three-phase conducting wire is being arranged on the top of described double loop tower head, and the limit phase conductor cross-arm 1 of this single loop tower head 10 is positioned at the middle part, and middle phase conductor cross-arm is positioned at leg-of-mutton top, and directly is hung on body of the tower.
Described single loop tower head 10 tops are provided with ground wire upper frame 7, because ground wire upper frame 7 presents the shape that Chinese character " is done " in conjunction with single loop road tower head 10, are called for this reason and do the font anchor support.
