Description
Technical field
The present invention relates to transformer station's technical field, a kind of arrangement shape of power distribution equipment HGIS equipment is concretely related to
Formula.
Background technology
Power distribution equipment is exactly the general name for the electric device that can control, receive and distribute electric energy.Its effect is up
It is rapid in the case of the transmission and reallocation of Shi Jinhang electric energy, failure to cut off faulty component and resume operation.Due to it functionally
It is complete, so, there must be the electrical equipment of various functions in power distribution equipment.As bus rod, breaker, keep apart
The equipment such as pass, reactor, arrester, transformer, reactive power compensator, connection conductor and measurement protection communication.Power distribution equipment one
As can be classified according to voltage class, or according to the difference on arrangement form, indoor, outdoor power distribution unit can be divided into.
HGIS is the abbreviation of gas insulation composite electric appliance, by different user the need for breaker, disconnecting switch, ground connection are opened
Close and transformer etc. element is integrated is closed in gas-insulated metal cell.New height of the HGIS equipment between GIS and AIS
Voltage switching station.HGIS structure is similar to GIS, but it does not include bus equipment.Its advantage is that bus is not loaded on SF6 air chambers,
It is exposed, thus wiring is clear, succinct, compact, installs and Maintenance and Repair are convenient, operational reliability is high.
With the continuous expansion of power network scale, Ultra-high Voltage Substations roll up, in addition environment and the pressure taken up an area, China
The type selecting of the main equipment of super-pressure 500kV transformer stations is just extremely important.At present, China 500kV ultra-high pressure switchs mainly have two big
Class:Gas-insulated metal fully-closed switch equipment GIS and conventional open style switchgear AIS.GIS, which has, to be taken up an area less, and operation can
High by property, the features such as anti-pollution and strong shock resistance, but its is expensive, and the short time is difficult to repair and extends difficulty after failure.
AIS is more cheap than GIS, but floor space is very big and live part is exposed more, limits transformer station's area is narrow and small and ring
The place application of border inclement condition.Because HGIS can integrate GIS and AIS advantage, while avoiding in both deficiencies, native land
Through the application and research of carrying out HGIS successively.
Domestic transformer station 500kV and 330kV voltage class mostly use one-and-half breaker wiring, due to one and half open circuits
The characteristics of device wiring, although reliability is higher, but breaker quantity is more, economy is not good, therefore before reliability is met
Put, 4/3 breaker connection form can be used, so as to improve cost performance.Current 500kV and 330kV voltage class is broken from 4/3
Road device wiring is generally four-row arrangement, and every 1 string of 4/3 breaker connection has 3 back into outlet, takes current four-row to arrange,
The string that normally enters to inlet-outlet line is irrealizable, as using increasing framework, this problem solved using the mode of crossing, with Denso
Putting occupation of land can significantly increase, it is impossible to meet the requirement of Economization on land, and base concrete consumption, basement process and framework steel
Amount expense can be significantly increased, and engineering overall economy quality is not good, and can bring inconvenience for construction in later period, operation and maintenance etc.,
Need a kind of new arrangement form badly.
The content of the invention
In order to solve the above technical problems, the present invention is directed to 4/3 traditional breaker connection form power distribution equipment arrangement form
Improved, original " four-row " arrangement is changed to HGIS " Σ " type arrangement is based on 4/3 breaker connection there is provided one kind
Under, 500kV and 330kV voltage class power distribution equipment HGIS equipment " Σ " type arrangement.
A kind of arrangement form of power distribution equipment HGIS equipment, including breaker in breaker 2,2M in 1M sides breaker 1,1M
3rd, 2M sides breaker 4, arrester voltage transformer 0, wherein, breaker 3 in breaker 2,2M in 1M sides breaker 1,1M,
2M sides breaker 4 is in turn connected into class " Σ " type, and arrester and voltage transformer 0 are built in HGIS equipment.
Further, described " Σ " type arrangement form is double-deck inlet-outlet line.
Wherein, described double-deck inlet-outlet line includes:1M buses casing air 5,1M sides outlet casing air 6, middle outlet
Casing air 7,2M sides outlet casing air 8,2M buses casing air 9;1M buses casing air 5 and 1M suspention buses 1 connect
Connect;1M sides outlet casing air 6 is connected with left side framework outlet 11, realizes upper strata outlet;During middle outlet casing air 7 is passed through
Portion's framework is connected with upper strata outlet 1 by cross-line 1;2M sides outlet casing air 8 is connected with lower floor outlet 1, is realized
Lower floor's outlet;2M buses casing air 9 is connected with 2M suspention buses 1.
Further, described " Σ " type arrangement form is three layers of inlet-outlet line.
Wherein, three layers of described inlet-outlet line include:1M buses casing air 5,1M sides outlet casing air 6, middle outlet
Casing air 7,2M sides outlet casing air 8,2M buses casing air 9;1M buses casing air 5 and 1M suspention buses 2 16 connect
Connect;1M sides outlet casing air 6 is connected through left side knock-on line 17 by cross-line 2 18 with transition wire jumper 19, and transition wire jumper 19 leads to
Cross cross-line 3 20 to be connected with upper strata outlet 3 21, realize upper strata outlet;Middle outlet casing air 7 leads to through middle knock-on line 22
Cross cross-line 4 23 to be connected with middle level outlet 24, realize middle outlet;2M sides outlet casing air 8 is connected with lower floor outlet 3 25,
