Abstract

The utility model discloses a kind of GIL structure, this structure comprises conductor, shell, supporting insulator and integrated particle capture device, described shell is triangular prism, all be connected with three at described conductor head and the tail two ends and be parallel to triangular prism cross section, extended line converges, and be mutually the described supporting insulator of 120 degree, the described supporting insulator other end is fixed on three drift angles of described shell section triangle.The utility model can realize GIL power transfer conduit well and transport stably and mounting and installation, and ensures the fixing impact not being subject to bad weather and geological condition of conductor.

Description

A kind of GIL structure
Technical field
The utility model relates to the technical field of gas-insulated transmission line, particularly relates to a kind of GIL structure.
Background technology
Gas-insulated transmission of electricity bus is at present for the outgoing line part of GIS gas-insulated switchgear, be connected with overhead wire and use, consider that in transformer station, substitute overhead wire from now on uses, and for the long distance join between transformer station, and the deadweight of GIL power transfer conduit is heavier, current GIL power transfer conduit has following deficiency:
1, circular power transfer conduit need have steelframe to support, and need arrange a steelframe every fixed range, need a large amount of use, and floor space is large during long distance powedr transmission;
2, a pair supporting insulator is firm not under adverse circumstances and geological conditions, may break down, affect operation power safety.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of GIL structure, can directly lay on the ground, and strengthens the supporting role to conductor.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of GIL structure, comprise conductor, shell, supporting insulator and integrated particle capture device, described shell is triangular prism, all triangular prism cross section is parallel to three at described conductor head and the tail two ends, extended line converges, and the described supporting insulator one end being mutually 120 degree connects, and the described supporting insulator other end is fixed on three drift angles of described shell section triangle.
The triangle of the cross sectional shape of described shell is equilateral triangle.
Described supporting insulator one end is fixed on each bisector of angle position of described shell section triangle.
When three-phase outlet, when described structure is placed, two pipeline fronts are placed on the ground, and another root pipeline is inverted and is placed in the middle of two pipelines, stacking installation.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts triangular prism-shaped shell, during laying installation more than ground, without the need to supporting steel frame, can be directly installed on horizontal plane, also can transport the pipeline of larger quantity during transport.The utility model adopts three supporting insulators, makes conductor not be subject to the impact of any adverse circumstances and geological condition, ensure that the firm of conductor, improve stability and the fail safe of transmission of electricity.Change the shape of GIL power transfer conduit, improve inner supporting structure, make GIL power transfer conduit more firm, improve the reliability of transmission of electricity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is three-phase outlet structure schematic diagram of the present utility model;
Wherein, 1 is conductor, and 2 is shell, and 3 is supporting insulator, and 4 is integrated particle capture device.
Embodiment
For making content of the present utility model more become apparent, be described further below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.As shown in Figure 1, a kind of GIL structure of the present utility model, comprises conductor 1, shell 2, supporting insulator 3 and integrated particle capture device 4; The shape of shell 2 is triangular prism, and namely the cross sectional shape of shell 2 is triangle, and in the utility model specific embodiment, the triangle of the cross sectional shape of shell 2 is equilateral triangle.One group of supporting insulator 3 is all connected with at conductor 1 head and the tail two ends, in the utility model, on cylindrical conductor 1, first weld two groups of supporting insulators 3 of a monic tail, often organize supporting insulator 3 and comprise three supporting insulators 3, supporting insulator 3 is parallel to triangular prism cross section, and extended line concentrates on the center of circle, and becomes 120 degree.In the shell 2 of triangular prism-shaped, the supporting insulator 3 of GIL structure head and the tail is welded and fixed with on three of the section triangle of shell 2 drift angles.When fixing, one end of supporting insulator 3 is fixed on each bisector of angle position of shell 2 section triangle.Namely conductor 1 is fixed on the center of described shell 2 inside.
Fig. 2 is three-phase outlet structure schematic diagram of the present utility model.As shown in Figure 2, when three-phase outlet, the shell of GIL structure can mutually embedding installation, namely can mutual stacking installation.When three pipelines are placed, two pipeline fronts are placed on the ground, and another root pipeline is inverted and is placed in the middle of two pipelines, is stacked up; Dramatically saves on floor space like this.
The utility model adopts triangular prism-shaped shell, during laying installation more than ground, without the need to supporting steel frame, can be directly installed on horizontal plane, also can transport the pipeline of larger quantity during transport.The utility model adopts three supporting insulators, makes conductor not be subject to the impact of any adverse circumstances and geological condition, ensure that the firm of conductor, improve stability and the fail safe of transmission of electricity.
Described in the utility model, concrete case study on implementation is only better case study on implementation of the present utility model, is not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, all should as technology category of the present utility model.
