Description
Technical field
The utility model relates to the technical field of gas-insulated transmission line, particularly relates to 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 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:
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, described supporting insulator 3 one end is vertically fixed on described shell 2, and the other end 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 is mutually corresponding.
The through hole radius of described supporting insulator 3 is identical with described conductor 1 radius.
Described 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, screw contacts has rotated and has ensured that insulating supporting is perpendicular to the ground, conductor can be completely fixed, conductor is made not to 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.
