Area about 2500m2DC de-icing device, cause huge waste, very very grave impact caused to the economy of engineering.
Content of the invention
In the presence of solving the problems, such as above-mentioned existing background technology, this utility model provides a kind of saving equipment and joins
The transformer station's exchange outlet line direct-current ice-melting bus structure put, save floor space, saved construction costs.
For achieving the above object, the transformer station's exchange outlet line direct-current ice-melting bus structure designed by this utility model,
Ice-melt bus B including transformer station B and DC ice melting complexes, the ice-melt of described DC ice melting complexes and transformer station B
Bus B is connected by ice-melt conductor, and it is characterized in that, also includes the ice-melt bus A of transformer station A, described ice-melt bus B and
Ice-melt bus A is connected by DC ice-melting, and the two ends of described DC ice-melting are respectively arranged with ice-melt and connect disconnecting switch.
Further, described ice-melt bus A connects disconnecting switch by ice-melt respectively has the friendship of ice-melt demand with several
Flow out line transmission line of electricity to connect, the offside transformer station of each described exchange outgoing-feeder circuit is provided with ice-melt short circuit and keeps apart
Close.
Further, described DC ice-melting is the transmission line of electricity between transformer station B and transformer station A, using existing transmission of electricity
Circuit, as ice-melt passage, saves equipment.
Principle of the present utility model is that setting ice-melt bus and ice-melt connect disconnecting switch, using power transformation in transformer station A
Stand built DC de-icing device in B, by the alternating current interconnection road between transformer station B and transformer station A, by DC de-icing device
The DC current producing sends into the ice-melt bus in transformer station A, realizes exchanging outlet ice-melt to other in transformer station A.
This utility model is realized the exchange of transformer station A is gone out using closing on built DC de-icing device in transformer station B
Line ice-melt, from saving device configuration, the angle saved floor space, save construction costs, improves the economy of engineering.
Brief description
Fig. 1 exchanges the structural representation of outlet line direct-current ice-melting bus structure for this utility model transformer station；
In figure：Transformer station B1, DC ice melting complexes 2, ice-melt bus B3, ice-melt conductor 4, transformer station A5, ice-melt is female
Line A6, DC ice-melting 7, ice-melt connects disconnecting switch 8, offside transformer station 9, ice-melt short circuit disconnecting switch 10, has ice-melt demand
Transmission line of electricity 11.
Specific embodiment
Below in conjunction with drawings and Examples, this utility model is described in further detail.
This utility model transformer station exchange outlet line direct-current ice-melting bus structure as shown in Figure 1, including transformer station A5
Ice-melt bus A6, the ice-melt bus B3 of transformer station B1, the DC ice melting complexes 2 of transformer station B1.DC de-icing device 2 one
As be made up of complete set of equipments such as converter power transformer, converter valve, reactor, switch tool and measurement apparatus, configure valve group capacity
200MW, DC voltage 45kV.The ice-melt bus B3 of DC ice melting complexes 2 and transformer station B1 is connected by ice-melt conductor 4.
Ice-melt bus B3 and ice-melt bus A6 is connected by DC ice-melting 7.DC ice-melting 7 can be between transformer station B1 and transformer station A5
Transmission line of electricity.The two ends of DC ice-melting 7 are respectively arranged with ice-melt and connect disconnecting switch 8.Ice-melt bus A6 passes through ice-melt respectively
The transmission line of electricity 11 that connecting disconnecting switch 8 has ice-melt demand with several is connected, and each has the transmission line of electricity 11 of ice-melt demand
It is provided with ice-melt short circuit disconnecting switch 10 in offside transformer station 9.
The 500kV exchange outlet 7 times of transformer station A5, outlet at a specified future date 11 times, except the exchange outlet 7 being connected with transformer station B1
Outward, other exchange outlets all have ice-melt demand, need to configure ice-melt bus A6 in station, in the configuration ice-melt of exchange outlet exit even
Connect disconnecting switch 8, to realize alternating current circuit ice-melt function.
It is configured with DC de-icing device 2 with transformer station A5 in more than ten kilometers of transformer station B1, valve group capacity 200MW,
DC voltage 45kV, is computed checking, and this DC de-icing device 2 major parameter meets 500kV exchange outlet in A5 transformer station and melts
Ice demand.
DC de-icing device 2 using configuration in transformer station B1 accesses in transformer station A5 through exchange outlet, transformer station A5
Interior installing ice-melt connects disconnecting switch 8 and ice-melt bus A6, realizes transformer station's alternating current circuit ice-melt.Transformer station A5 is respectively being exchanged
During any one ice-melt back into row in circuit, need one loop line road between transformer station B1 and transformer station A5 of simultaneously stopping transport, and changed
For the DC ice-melting method of operation.In view of ice-melt is typically scheduled at, low ebb load period in winter is carried out and deicing processes only maintain number little
When, now system loading is less, and the requirement to grid transmission ability is relatively low, and the therefore impact to system operation for the ice-melt scheme is can
The safe and reliable operation of ice-melt period electrical network in the range of control, can be ensured by the appropriate arrangements method of operation.
Other unspecified parts are prior art.
