Description
Technical field
220kV double space modular HGIS electric wiring device of the present invention, belongs to project of transmitting and converting electricity design and construction
Technical field.
Background technique
In China, 220kV power grid belongs to the bulk transmission grid of sharing of load, systematic affinity at the generally presentation of 220kV power distribution equipment
Important, the sweeping feature of inlet-outlet line, main electrical scheme generallys use double-bus or double-bus section wiring.Common 220kV is opened
Close equipment: 1. air insulation switchs (air insulated switchgear, AIS) type；2. potting breaker type；③HGIS
Type；Gas-insulated switch 4. (gas insulated switchgear, GIS) type.2. 1. generally incorporate into as open type equipment,
And it 3. and 4. then incorporates into as compact device.With socio-economic development, environment etc. is being economized on resources and protected for substation
The requirement of aspect is continuously improved, and compact device relies on highly integrated, characteristics of compact layout, outer dimension is small, place is adaptable etc.
Technical characterstic is widely applied, and especially GIS device application is more extensive.
In recent years, with the expansion of domestic GIS device application range, people have found that GIS power distribution equipment is deposited more and more
In problems.First is that enlarging power failure coverage is big, or even cause bus full cut-off；Second is that bus gas leakage risk is big, have a power failure inspection
Repair risk height；Third is that foundation of civil work project amount amount is big, and difficulty of construction is high；Fourth is that when to reduce power failure when enlarging as far as possible
Between, lead to the first stage of investment increased costs.Especially in the 220kV of power distribution equipment open air arrangement and the above substation, work as 220kV
It is more that number is returned in outlet, and mostly uses overhead outlet, according to GIS device, then generally requires to extend bus, not only increases investment but also be difficult to
Efficiently use the advantage of GIS characteristics of compact layout.
The device integration that HGIS has as GIS is high, technologically advanced, characteristics of compact layout, maintenance less, the service life it is long etc. excellent
Point, and also have many advantages, such as that enlarging is convenient and power off time is short, coverage is small, but when also existing simultaneously double bus scheme
The problems such as casing quantity is multiplied, especially occupied area increase excessively compared to GIS, its application is caused to be restricted.And
How to realize that land occupation is saved, investment is saved and the balance of the convenient three of O&M, this just needs the equipment to existing conventional H GIS
Pattern is studied.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide one kind can adapt to completely double-bus with
And the power distribution equipment of double bus scheme arranges demand, while realizing that land occupation is saved, investment is saved and the convenient three's demand of O&M
The 220kV double space modular HGIS electric wiring device of balance.
The object of the present invention is achieved by the following technical solutions, and a kind of 220kV double space modular HGIS is electrical
Termination, it includes: the 220kV HGIS power distribution equipment of double-bus and double-bus section wiring towards outdoor arrangement, normal
On the basis of advising HGIS dually arrayed, two interval groups are combined by a set of HGIS module using GIL pipeline, and share one group of bus sheath
Pipe, using the double-fracture bus isolating switch connection bus casing.
As preferred: described one group of bus casing that shares is two SF6- for being spaced shared one group of connection open type bus
Casing air, and configured using double-fracture bus isolating switch.
As preferred: the double-fracture bus isolating switch is arranged respectively at outlet and into the double-bus of (out) line, and
Configured with outlet casing tube and inlet-outlet sleeve, it is respectively set on GIL pipeline between the outlet and double-bus into (out) line
The IM bus casing and IIM bus casing for having double space shared.
As preferred: the double-fracture bus isolating switch is arranged respectively in the double-bus of outlet and mother, and is configured
There is outlet casing tube, is respectively arranged with the shared IM bus of double space on GIL pipeline between the outlet and the double-bus of mother
Casing and IIM bus casing.
As preferred: the double-fracture bus isolating switch is arranged respectively in female double-bus set, is set in segmentation and mother
Double-bus between double space shared IM bus casing and IIM bus casing are respectively arranged on GIL pipeline, and in the IM
Double-fracture bus isolating switch is each provided in segmentation on GIL pipeline between bus casing and IIM bus casing.
The present invention is primarily introduced into modular design concept, and conventional H GIS dually arrayed mode is integrated and optimized, and leads to
It crosses and is configured using " bus casing " sharing mode and double-fracture bus isolating switch, i.e., two are spaced shared one group of connection open type
The SF6- casing air of bus, shared bus casing rated current can carry out flexible choice according to different interval combined situation,
Double-fracture bus isolating switch connects the configuration of bus casing, in enlarging since the double-fracture bus isolating switch that will be reserved is beaten
It opens, one fracture gas chamber leakage will not influence another fracture gas chamber when docking operation, and fracture plays normal insulation buffer action,
Original part operation is not influenced.Any two interval Combination Design is a set of by the flexibility characteristics for efficiently using GIL pipeline
HGIS module.The present invention avoid interval influence each other and meet bus casing through-flow requirement under the premise of, realize single main transformer,
Route, mother, segmentation and female independent assortment for setting interval.
Scheme compared to the prior art, the beneficial effects of the present invention are:
1) on the basis of retaining conventional H GIS dually arrayed advantage, two spaced design groups are combined into a set of HGIS module, are led to
Common bus casing is crossed, equipment investment is not only saved, but also has compressed interval longitudinal size 5.5m, occupied area can be bis- compared with conventional H GIS
Column arrangement reduces 40% or more.
2) by using double-fracture bus isolating switch configure, either operation regulation or a certain interval extend or
Breaker overhaul can avoid influencing each other under the two various operating conditions in interval.
3) using equipment combination of sets at optimization reduces the interval HGIS quantity, such as will be between bus equipment interval and bus section
Every equipment combination of sets at, by mother interval and section gap equipment combination of sets at etc..
4) double space modular 220kV HGIS design scheme is technologically advanced, is particularly suitable for modularization construction, not to basis
Uniform settlement requires low, foundation engineering amount saving, and extends flexibly, and power failure coverage is small, is particularly suitable for the junction 500kV
The more occasion of 220kV overhead outlet.
