Abstract
The utility model discloses a kind of gas insulation electric power line, comprise some line units, described line unit comprises housing and the conductor of coaxial setting, insulating supporting dish is set between described housing and described conductor, described housing two ends arrange mounting flange, the structure of the similar concavees lens that the little peripheral thickness of thickness is large centered by described insulating supporting dish.Described housing is provided with stockbridge damper, and described stockbridge damper comprises two hollow hammer bodies, is provided with the air bag be communicated with described housing communicating pipe in described hammer body.By arranging insulating supporting dish between the housing and conductor of coaxial setting, thus improve the warping resistance ability of body tube with imitating, be convenient to long distance erection, effectively can reduce the erection quantity of support, simultaneously, described insulating supporting dish adopts the structure of the similar concavees lens that the little peripheral thickness of center thickness is large, thus effectively form the biomimetic features of similar ring, and bend resistance ability is greatly improved.
Description
Technical field
The utility model relates to gas-insulated transmission line technical field, is specifically related to a kind of cellular construction of gas insulation electric power line.
Background technology
At present, traditional transmission & distribution power delivery mode mainly contains overhead transmission line conveying and cable line dispensing, and overhead transmission line loss is large, and cable line one side line loss is comparatively large, and current-carrying is limited on the other hand, needs to be equipped with reactive power compensator.Therefore, create gas-insulated transmission line in recent years, by filling insulating gas between conductor and shell body, realize the electric power conveying of high voltage, big current, loss is low, and safety is good, is convenient to realize Large Copacity long distance transmission & distribution power transmission.But due to fed distance large, although shell body diameter is relatively large, for open air erection its anti-seismic performance of safety with to do bending limited in one's ability, often need comparatively dense ground erection bracket.As publication No. gas-insulated transmission line disclosed in the patent of invention of CN 103795017A that on May 14th, 2014 announces, namely there are the problems referred to above.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides that a kind of structure is simple, bend resistance ability strong, makes in long distance erection, the gas insulation electric power line effectively reducing erection bracket.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of gas insulation electric power line, comprise some line units, described line unit comprises housing and the conductor of coaxial setting, insulating supporting dish is set between described housing and described conductor, described housing two ends arrange mounting flange, the structure of the similar concavees lens that the little peripheral thickness of thickness is large centered by described insulating supporting dish.
The conductor perforations that described insulating supporting dish comprises center and the air-vent be laid in around described conductor perforations.
The ring flange of described shell one end is laid with multiple through hole, the ring flange of the other end is laid the set bolt that multiple and described through hole is corresponding.
Described housing two ends are all sealed by insulating panel, and wherein the conductor of one end exposes described insulating panel, and the conductor of the other end is recessed into described insulating panel, are formed and the groove exposing insulating panel end conductor and match.
Described housing is provided with stockbridge damper.
Described stockbridge damper comprises two hollow hammer bodies, is provided with the air bag be communicated with described housing communicating pipe in described hammer body.
Gas insulation electric power line of the present utility model, by arranging insulating supporting dish between the housing and conductor of coaxial setting, thus improve the warping resistance ability of body tube with imitating, be convenient to long distance erection, effectively can reduce the erection quantity of support, meanwhile, described insulating supporting dish adopts the structure of the similar concavees lens that the little peripheral thickness of center thickness is large, thus effectively form the biomimetic features of similar ring, bend resistance ability is greatly improved.Described housing two ends arrange mounting flange, are connected by ring flange, by sealing gasket on pad between ring flange, be not only tightly connected reliable, and structure are simple, easy and simple to handle.By arranging conductor perforations at the center of insulating supporting dish, can effectively power line conductor be placed through wherein, and then realize effectively spacing to conductor, lay air-vent simultaneously, the insulating gas in power transmission line is facilitated to circulate, make the gas pressure distribution of same section even, and be convenient to regulate the insulating gas of whole power transmission line to distribute.By laying corresponding through hole and set bolt respectively on the ring flange at housing two ends, the incorrect link that can effectively avoid housing mutual, thus effectively realize the exact connect ion between two sections of power transmission lines.By arranging stockbridge damper on housing, can effective guarantee erection power transmission line undermined when running into the sharp poundings such as earthquake, improve the shock resistance of power transmission line.By stockbridge damper is being set to hollow-core construction, and the air bag be communicated with described housing is set in described hollow-core construction, effectively can realize the cushioning effect to insulating gas in power transmission line, avoid too high or too low for temperature cause housing internal gas pressure change excessive, be damaged to power transmission line, thus safe, stable, the reliability service of effective guarantee power transmission line.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model insulating supporting dish;
Fig. 3 is that the a-a of the utility model insulating supporting dish is to sectional structure schematic diagram.
Embodiment
