The configuration system that multiple outgoing line intervals are extended for old-fashioned substation of power and power supply reliability.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of configuration system for extending multiple outgoing line intervals for old-fashioned substation, it is by bus framework, aerial main bus-bar
Device, HGIS outgoing line interval equipment, outlet downlead, outlet structure are constituted, it is characterised in that: and bus framework is provided with two groups,
Aerial main bus device is erected between two groups of bus frameworks, is maked somebody a mere figurehead main bus device and is passed through between outlet downlead and HGIS outlet
It is connected every equipment, the other end of HGIS outgoing line interval equipment connects outlet structure by outlet downlead；The HGIS outlet
Spacing devices are by breaker, terminal box, current transformer, disconnecting switch, high speed grounding switch, connection busbar and interior fill SF6
The metal sealing tank of gas forms；The aerial main bus device is by steel-cored aluminium strand, strain insulator string and is coupled gold
Tool composition；The outlet downlead includes steel-cored aluminium strand, T-type wire clamp and device clamp.
The distance H1 on the bus framework apogee distance ground is 7.3m.
Lightning conducter is installed on the outlet structure most vertex, and the distance H2 apart from ground is 12.5m.
The distance H3 on the outlet downlead apogee distance ground is 10m.
The settable one or more of HGIS outgoing line interval equipment.
The beneficial effect of the utility model compared with prior art is:
A kind of configuration system for extending multiple outgoing line intervals for old-fashioned substation is realized in existing old-fashioned AIS power transformation
It stands in the case where can not extending electricity consumption outward, using limited existing vacant area, increases outgoing line interval newly, make previously extend
The power distribution equipment of outgoing line interval has the condition for extending multiple outgoing line intervals, effectively improves the work effect of old-fashioned AIS substation
Energy and power supply reliability, have saved land resource, solving existing old-fashioned AIS substation can not rise in the case where limited space
The problem of grade promotes accessing user's quantity and power supply reliability.
Detailed description of the invention
Fig. 1 is a kind of overlooking structure diagram of configuration system that multiple outgoing line intervals are extended for old-fashioned substation；
Fig. 2 uses structural schematic diagram for a kind of configuration system for extending multiple outgoing line intervals for old-fashioned substation.
In figure: 1, HGIS outgoing line interval equipment, 2, aerial main bus device, 3, bus framework, 4, outlet structure, 5, outlet
Downlead.
Specific embodiment
This extends the configuration system of multiple outgoing line intervals for old-fashioned substation, it is filled by bus framework 3, aerial main bus-bar
It sets 2, HGIS outgoing line interval equipment 1, outlet downlead 5, outlet structure 4 to constitute, it is characterised in that: bus framework 3 is provided with two
Group, aerial main bus device 2 are erected between two groups of bus frameworks 3, the distance on the 3 apogee distance ground of bus framework
H1 is 7.3m.Aerial main bus device 2 is connect by outlet downlead 5 with HGIS outgoing line interval equipment 1, and HGIS outgoing line interval is set
Standby 1 other end connects outlet structure 4 by outlet downlead 5；The most vertex of outlet structure 4 is installed by lightning conducter, distance
The distance H2 on ground is 12.5m.The distance H3 on the 5 apogee distance ground of outlet downlead is 10m.The HGIS goes out
Line spacing devices 1 are by breaker, terminal box, current transformer, disconnecting switch, high speed grounding switch, connection busbar and interior fill
The metal sealing tank of SF6 gas forms；The settable one or more of HGIS outgoing line interval equipment 1.The aerial master
