Description
Technical field
The present invention relates to the combined electrical apparatus arrangement that a kind of electric power system is used.
Background technology
The high pressure combined electrical apparatus has become the main flow form of the above electric pressure of 72.5kV transformer station.The high pressure combined electrical apparatus is divided into full combined electrical apparatus (GIS) and half combined electrical apparatus (HGIS), and the GIS bus is enclosed in SF
6In the gas, the HGIS bus exposes, and this is the main difference of the two.HGIS is lower than GIS cost, but owing to be bare bus bar, so HGIS takes up an area of greatly.HGIS is not suitable for being used in and requires no high pressure exposed point, the little transformer station of occupation of land, in the logical common GIS of this transformer station.Transformer station develops to the unattended operation direction, drops to minimum GIS to the high pressure exposed point and more has superiority than HGIS.Replace short-range overhead wire, high-tension cable and SF with the capacitor type isolated bus
6The gas enclosed busbar can expedite the emergence of out the New Combined Switchgear arrangement, and New Combined Switchgear arrangement cost is low, and is simple in structure, SF
6Gas usage reduces a lot, has reduced the high pressure exposed point to greatest extent, meets transformer station and develops to the unattended operation direction.
Summary of the invention
The purpose of this invention is to provide that a kind of cost is low, simple in structure, SF
6The novel annular close-coupled combined electrical apparatus arrangement that gas usage is few, can reduce the high pressure exposed point to greatest extent.
The objective of the invention is to realize like this: the novel annular close-coupled combined electrical apparatus arrangement of the present invention comprises some inlet wires interval, some outlets interval, some inlet wire capacitor type insulating buses, some outlet capacitor type insulating buses, SF
6Gas bus distributor, said SF
6Gas bus distributor is positioned at the centre position and connects all inlet wires intervals and outlet interval, and all annular compact Layout in all inlet wires intervals and outlet interval is in said SF
6Around the gas bus distributor.
Have at least a said inlet wire to adopt inlet wire capacitor type insulating bus to be connected to said inlet wire inlet wire loop at interval at interval, or have at least a said outlet to adopt outlet capacitor type insulating bus to be connected to the line loop that at said outlet interval at interval.
Said inlet wire interval and outlet are three-phase combined type at interval, also can be the three-phase branch mailboxes.
Said SF6 gas bus distributor side has several docking ports to be connected at interval with outlet at interval with some said inlet wires.
Above the said SF6 gas bus distributor, below have docking port and voltage transformer and lightning arrester to connect and compose bus distribute to measure protection at interval.
The beneficial effect of the novel annular close-coupled combined electrical apparatus arrangement of the present invention is: each inlet wire adopts inlet wire capacitor type insulating bus, outlet capacitor type insulating bus to be connected respectively with going out line loop with inlet wire loop, outlet at interval at interval, and uses SF
6Gas bus distributor substitutes main bus bar, without the bus expansion appliance, reduces SF in a large number
6Gas usage; Combined electrical apparatus manufacturer need not to consider on-the-spot and carries out the standard modular design and reduce production costs and design cost, reduce on-the-spot Installation and Debugging workload simultaneously, so the outfit of equipment cost reduces a lot.The present invention has reduced the sapce charge usefulness of HGIS because of adopting bare bus bar to increase, and is that a kind of cost is low, simple in structure, SF
6The novel annular close-coupled combined electrical apparatus arrangement that gas usage is few, can reduce the high pressure exposed point to greatest extent.
