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

The purpose of the utility model is to overcome the shortcomings of the prior art, and double mothers can be adapted to completely by providing one kind The power distribution equipment of line and double bus scheme arranges demand, while realizing that land occupation is saved, investment is saved and the convenient three of O&M The 220kV double space modular HGIS electric wiring device of demand balance.

The purpose of this utility model is completed by following technical solution, a kind of 220kV double space modular HGIS Electric wiring device, it includes: the 220kV HGIS power distribution equipment of double-bus and double-bus section wiring towards outdoor arrangement, On the basis of conventional H GIS dually arrayed, two interval groups are combined by a set of HGIS module, and shared one group of mother using GIL pipeline Thread casing, using the double-fracture bus isolating switch connection bus casing.

As preferred: shared one group of bus casing is two and is spaced the SF for sharing one group of connection open type bus₆ Casing air, and configured using double-fracture bus isolating switch.

As preferred: the double-fracture bus isolating switch is arranged respectively in the double-bus of outlet and inlet-outlet line, and is matched It is equipped with outlet casing tube and inlet-outlet sleeve, is respectively arranged on GIL pipeline between the outlet and the double-bus of inlet-outlet line double Interval shared IM bus casing and IIM bus casing.

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 utility model is primarily introduced into modular design concept, conventional H GIS dually arrayed mode integrate excellent Change, configured by using " bus casing " sharing mode and double-fracture bus isolating switch, i.e., two are spaced shared one group of connection The SF of open type bus₆Casing air, shared bus casing rated current can carry out flexible according to different interval combined situation Selection, double-fracture bus isolating switch connect the configuration of bus casing, the double-fracture bus isolation in enlarging due to will reserve Switch is opened, and one fracture gas chamber leakage will not influence another fracture gas chamber when docking operation, fracture play normal insulation every From effect, original part operation is not influenced.The flexibility characteristics for efficiently using GIL pipeline, by any two interval Combination Design For a set of HGIS module.The utility model avoid interval influence each other and meet bus casing through-flow requirement under the premise of, it is real Now single main transformer, route, mother, segmentation and female independent assortment for setting interval.

Scheme compared to the prior art, the beneficial effects of the utility model are:

1) on the basis of retaining conventional H GIS dually arrayed advantage, two spaced design groups are combined into a set of HGIS mould Block not only saves equipment investment by common bus casing, but also has compressed interval longitudinal size 5.5m, and occupied area can be relatively conventional HGIS dually arrayed scheme 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.
