Abstract
The utility model discloses a kind of GIL structure, this structure comprises conductor, shell, supporting insulator, spiral contact, particle capture device and Site Welding place, described supporting insulator is fixed on described shell, be concentric structure with described conductor, hollow parts radius is consistent with described conductor radius, and described spiral contact overcoat has described particle capture device.The utility model can realize being completely fixed of GIL power transfer conduit conductor, and ensures that the conductor contact of two segment pipes is good.
Description
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, plug-in type contact can not ensure that conductor contact is good, may cause loose contact, affect transmission reliability;
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 1, shell 2 and supporting insulator 3, described conductor 1 is arranged in described shell 2, described conductor (1) is connected by supporting insulator described in several (3) with described shell (2), the cross sectional shape of described supporting insulator (3) is consistent with described shell (2) cross sectional shape, described supporting insulator (3) cross section the best part is connected with described shell (2), and its core offers for the through hole through conductor (1).
Outside described conductor 1 one end, offer screw thread, inside the other end, offer screw thread, the two in correspondence with each other.
Described shell (2) is cylinder blanket, and described supporting insulator (3) is cone insulator or spool insulator.
The through hole radius of described supporting insulator 3 is consistent with described conductor radius.
Each GIL structure has two described supporting insulators 3, is arranged on the part end to end of GIL structure.
Compared with prior art, the beneficial effects of the utility model are: the supporting insulator that the utility model adopts, and can be completely fixed conductor, make 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.Particle capture device is installed in GIL structure two ends end to end, and the particulate entering GIL structure in installation process can be captured in time, ensure that in conductor transmission of electricity process and does not produce the faults such as electric arc that the particulate that enters GIL structure because of installation causes.Improve inner supporting structure, make GIL power transfer conduit more firm, improve the reliability of transmission of electricity.
