Abstract
The utility model discloses an earthing structure for GIS equipment earthing by the adoption of a single copper stranded wire. The earthing structure comprises a hard copper stranded wire, a copper wire end and an earth wire. The hard copper stranded wire contains a first end and a second end. The first end of the hard copper stranded wire is connected to a GIS equipment earth point through the cooper wire end. The second end of the hard cooper stranded wire is connected to the earth wire in an earthing hole. According to the utility model, on the basis of guaranteeing safe and reliable earthing, construction difficulty is reduced, earthing materials are saved, and the technological design is beautiful.
Description
Technical field:
The utility model belongs to the high voltage equipment field, and particularly the single copper stranded conductor of a kind of employing carries out the GIS(Cubicle Gas-Insulated Switchgear) ground structure of equipment ground.
Background technology:
Growth at full speed along with national economy, domestic a large amount of 330kV, 500kV, 750kV and 1000kV transformer station build successively and put into operation, it is also increasing that index is taken up an area in transformer station, and the soil becomes day by day valuable as non-renewable resources, therefore a lot of transformer stations all design and have adopted the GIS(Cubicle Gas-Insulated Switchgear) power distribution equipment, can save occupation of land with respect to unenclosed construction.Yet aspect GIS equipment ground, each producer and each engineering have adopted a variety of methods, if any earthing block is set on the ground, by band steel, equipment ground point is connected to the ground earthing block, have and adopt that the double joint copper stranded conductor draws down to the ground connection major network etc., all there are the problems such as technique is not attractive in appearance, construction inconvenience, earthing material waste in above method.Therefore, being necessary GIS equipment ground in transformer station is studied, is mainly to solve following problem: 1, how to save earthing material, cost saving; 2, how to make grounding construction convenience and technique attractive in appearance; The generation of the electrochemical corrosion reaction when 3, how to avoid copper and band steel to join guarantees that grounding safety is reliable.
The utility model content:
The purpose of this utility model is to provide a kind of ground structure that adopts single copper stranded conductor to carry out GIS equipment ground that can satisfy actual requirement of engineering, to solve the problems of the technologies described above.
For achieving the above object, the utility model takes following technical scheme to be achieved:
A kind of ground structure that adopts single copper stranded conductor to carry out GIS equipment ground comprises hard drawn copper strand wire, copper cash nose and earth connection; Hard drawn copper strand wire comprises the first end and the second end; The first end of hard drawn copper strand wire is connected to GIS equipment ground point by the copper cash nose; The second end of hard drawn copper strand wire is connected on earth connection in ground connection is cheated.
The utility model further improves and is: described ground connection is filled with plain concrete in the hole.
The utility model further improves and is: the second end of hard drawn copper strand wire is welded and fixed by heat release with earth connection and is connected.
The utility model further improves and is: described earth connection connects the ground connection major network.
The utility model further improves and is: described earth connection is grounding flat steel, grounding copper twisted wire or grounding copper bar.
The utility model further improves and is: the copper cash nose is bolted to connection GIS equipment ground point.
In the utility model, the cross section of hard drawn copper strand wire is determined by the thermally-stabilised verification of earth short circuit current.
With respect to prior art, the utility model advantage is:
1, adopt single copper stranded conductor to carry out GIS equipment ground, saved construction investment;
2, adopt single copper stranded conductor to carry out GIS equipment ground, need not to arrange the ground earthing block, lowered difficulty of construction, can make construction technology more attractive in appearance;
3, complete the heat release welding of copper stranded conductor and earth electrode in ground connection is cheated, avoid joint to expose, technique is attractive in appearance, avoids joint to be placed in the contingent electrochemical corrosion of soil.
4, complete the welding of copper stranded conductor and earth electrode after, cast plain concrete docking melt pit seals, and avoids cheating the internal water accumulation laying dust.
5, the copper cash nose is easy to disconnect, and facilitates grounded circuit to detect.
Description of drawings:
Fig. 1 is the front view of the utility model ground structure;
Fig. 2 is the end view of the utility model ground structure;
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1,2, a kind of ground structure that adopts single copper stranded conductor to carry out GIS equipment ground of the utility model comprises hard drawn copper strand wire 1, copper cash nose 2 and earth connection 3; Hard drawn copper strand wire 1 comprises the first end 11 and the second end 12.After GIS equipment installation in position, the copper cash nose 2 that employing is applicable to the GIS apparatus body is connected to GIS equipment ground point with the first end 11 of hard drawn copper strand wire 1, be soldered on earth connection 3 in ground connection hole 4 interior the second end 12 heat releases with hard drawn copper strand wire 1, earth connection 3 is grounding flat steel, grounding copper twisted wire or grounding copper bar, and it connects the ground connection major network.After completing welding, with plain concrete, that ground connection hole 4 cast are flat.
By adopting this ground structure, having guaranteed to have reduced difficulty of construction under the reliable prerequisite of grounding safety, saved earthing material, and technique is attractive in appearance, for GIS equipment ground provides a new optimal solution.
Above content is in conjunction with concrete preferred implementation further description made for the present invention; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of submitting to.
