1) the indoor GIS bilayer "-" type overhead outlet compact arrangement scheme of 220kV, this scheme hereinafter referred to as " bilayer one
Font outlet compact scheme ".The electrical scale of this programme still uses 4 times 220kV inlet wires, 14 times 220kV outlets, main equipment
Gas-insulated switchgear GIS is selected, line side arrester selects conventional pillar Zinc-Oxide Arrester, line side voltage transformer
Select conventional column type capacitor formula voltage transformer.
This programme 220kV main equipment gas-insulated switchgear GIS is arranged in single layer power distribution equipment building, is only used for wiring
GIS bushing be arranged in ground outside building, specific arrangement is as follows: entrance bushing is arranged side by side with upper layer high position outlet casing tube
Close to main transformer place, casing height is 5.5 meters~6.5 meters.Lower layer's low level outlet casing tube is disposed adjacent to route outlet place,
Casing height is 7.0 meters~8.0 meters.Consider high-tension apparatus electrical safety distance, 220kV GIS bushing centre distance
220kV power distribution equipment building building axis line center is 3.50 meters.GIS entrance bushing accesses main transformer cross-line through flexible circuit conductor wire jumper, most
Transformer side is become owner of in terminating.The upper layer GIS high position outlet casing tube bounces through flexible circuit conductor and accesses the outlet of a upper layer high position, upper layer high position outlet
Across 220kV power distribution equipment roof, roof is disposed with leakage conductor and CVT, and equipment mounting height is 14~15 meters, equipment
Top is connected in the high position outlet of upper layer by flexible circuit conductor.GIS lower layer low level outlet casing tube is low through flexible circuit conductor wire jumper access lower layer
Position outlet, while drawing lower access ground line arrester and CVT.
This programme makes full use of the space of 220kV power distribution equipment roof, and the plane formula electrical equipment of script is arranged upgrading
For multiple field, rectilinear arrangement, at the same by horizontal direction, ground configuration electrical equipment between distance optimize, further compress
The longitudinal size in 220 kilovolts of places.The electrical horizontal layout of scheme after optimization is detailed in Fig. 2.
2) determination of the double-deck outlet hanging point height: 14.0~15.0 meters of designs of lower layer's low level outlet hanging point routinely, on
The electrification clear distance of interruption maintenance, the hanging point of upper layer high position outlet are pressed when the high-order outlet hanging point of layer needs to meet upper and lower level outlet difference
22.0~23.0 meters of designs.
3) solution the problems such as roof arrester, the carrying of CVT, maintenance, maintenance, enlarging: the branch of roof arrester and CVT
Frame height can meet operation maintenance personnel and closely make an inspection tour equipment, roof arrester and CVT are arranged in the same of roof by 2.5 meters of considerations
Side, the other side set 2.5 meters of wide access paths.
4) bounce outlet hanging point height determination: when roof plant maintenance, need to consider top electrification cross-line safety away from
From.Roof height adds equipment conveying by 4.0 meters of considerations by 11.0~12.0 meters of considerations, device height (containing travelling bogie)
When, equipment gabarit is to without blocking 2.55 meters of the distance between live part, and arc sag considers 1.5 meters, that is, framework hanging point must not
Less than 19.05~20.05 meters.
5) saved land occupation, reduced construction investment: this arrangement significantly reduces civilwork engineering quantity, and 220 kilovolts
Distribution place occupied area is 4824 square metres, close with outdoor single layer "-" type outlet scheme land requisition index, than indoor single layer
The land requisition index of "-" type outlet scheme has dropped about 20.4%；Construction area is 1440 square metres, than indoor single layer "-" type
The building land requisition index of outlet scheme has dropped about 22.6%.GIS main bus-bar length is had compressed simultaneously, than indoor single layer "-" type
The bus investment of outlet scheme can reduce about 23%, reduce the equipment investment of GIS.
This arrangement improves the running environment of GIS, can greatly improve the index that saves land when the indoor GIS of 220kV is arranged,
It can be widely applied to 220 KV distribution device sides of 500 kv substations；Have an advantage in that the running environment for 1) improving GIS,
The failure rate for reducing GIS, improves system reliability.2) meet O&M it is convenient under the premise of, by GIS outgoing line interval biserial
Arrangement, is cleverly utilized the room 220kVGIS roofing space, has saved land occupation.3) construction area of 220 kilovolts of rooms GIS is effectively pressed
Contracting, reduces civilwork engineering quantity.4) 220 kilovolts of GIS bus lengths are shortened, equipment investment is reduced.
Particular embodiments described above has carried out further the purpose of the present invention, technical scheme and beneficial effects
