At present, state, inside and outside large-scale GIS substation equipment are all in accordance with the design principle of tradition substation bus arrangement.Example
The GIS device majority of large-scale load-center substation 110kV as, 220kV uses sectionalized single busbar connection or the wiring of double-bus segmentation
Mode.Single-trunk segmental wiring has feature simple, economic, convenient, it is adaptable to 110kV, 220kV feeder line is the power transformation of 4 times
Stand；Double-bus section wiring can overhaul bus in turn, and flexibly, enlarging is convenient in scheduling, it is simple to test, it is adaptable to 110kV,
220kV feeder line transformer station more than 6 times.
GIS device arrangement typically uses level outdoors to arrange, component voltage grade plane figure and indoor layering, point electricity
Pressure grade building body layout.
The major advantage of GIS has:
Floor space is little, floor space is conventional equipment the 37% of general 220kV GIS device；110kV GIS device accounts for
Ground area is about the 46% of conventional equipment, meets the fundamental state policy that China saves the area, decrease expropriation of land, remove, reparation etc. high
Expensive front-end fee is used.
Owing to the element of GIS device is fully closed, the impact of the environment such as the most contaminated, salt fog, humidity.GIS
The current-carrying part housing shroud of equipment, ground connection is good, and the noise that the radiation of electric conductor generation, electric jamming, chopper cut-off is equal
By housing shroud, and GIS device is fixedly mounted on the built-in fitting of basis, and Gravity Centre of Product is low, and intensity is high, has excellent
Good earthquake-proof function, is particluarly suitable for down town or residential block and uses.Compared with conventional equipment, GIS is easier to meet city
The requirement of environmental protection.
SF6 gas itself does not burns as dielectric, gas, and fire protecting performance is good, and has the insulating properties of excellence
And arc extinction performance, safe and reliable to operation, maintenance workload is few, and the time between overhauls(TBO) is long, is suitable for Unattended substation, reaches to subtract people
The purpose of potentiation.
Construction period is short.Each element highly versatile of GIS device, uses modular construction, is assembled in a transport single
In unit, transport to job site in place fixing.Field erected workload decreases about 80% than conventional equipment.
On existing GIS transformer station layout design basis, the most further reduce floor space, reduce staggered across
Line, preferably promotes GIS transformer station advantage so that it is be more suitable for a new band intelligent grid composition and management is that this area is the most thirsty
Prestige solves the technical problem that.

Floor space is 11988 square metres.After using ring radiation shape GIS layout design, annular diameter 75 meters, the annular calculated accounts for
Ground area is 4415 square metres.
2, increase into and out of line interval: as a example by somewhere 220kV Xin Li GIS transformer station: 220kV design and installation has 13 times
Electrical separation, 66kV design and installation has 27 times electrical separations.After using ring radiation shape GIS layout design, 220kV increases to
17 times electrical separations, 66kV increases to 44 times electrical separations.
3, inlet wire, outlet wiring are flexibly: along with electrical network economy ground is fast-developing, to various clean energy resourcies and regenerative resource
Be connected to the grid ground Requirement Increases, can comprehensive inlet wire, the load-center substation of outlet layout design, be more suitable for following intelligent grid
Build and need.After GIS transformer station 220kV and 66kV layering is circular layout, layering ring busbars all directions can be according to user
Demand adjusts the layout of inlet wire and outlet neatly.
4, avoid or reduce high tension overhead way interleave cross-line: it is known that 220kV GIS combination electric appliance outgoing line interval
It is greater than 66kVGIS combined electrical apparatus outgoing line interval.Postponing at the ring radiation shape hierarchal arrangement cloth that interlocks, 220KV GIS combines electricity
Device outlet and 66KV GIS combination electric appliance outlet are that staggered layering is installed, and this novel electric arrangement ensure that each voltage
The outlet of grade meets the safe distance of electrical design, has used ring radiation to disperse this characteristic to ensure that this set side just
The feasibility of case and novelty.
5, ring busbars part builds: being changed original straight line GIS bus into ring busbars by rectilinear generatrix, ring busbars are
It is made up of the polygon merogenesis rectilinear generatrix with fixed installation angle.220kV with 66kV is divided by ring busbars layout design
Layer is arranged, wherein 220kV equipment interval is arranged on upper strata bus, and 66kV equipment interval is arranged on lower floor's bus.
6, underground GIS Substation Design it is adapted for mount on: ring radiation shape GIS transformer station arranges and also is adapted for being arranged on underground
GIS transformer station full cable line is arranged.
