Description
Technical field
The present invention relates to the arrangement in overhead outlet loop of the same name in GIS high voltage distribution installation, be concretely double
The bus solid arrangement of bus list segmentation power distribution equipment.
Background technology
In high voltage distribution installation, gas-insulating and fully-enclosed power distribution equipment (GIS) and the most conventional air-insulated routine
Power distribution equipment (AIS) is compared, and has the advantages such as floor space is little, safety reliability high, maintenance workload is little, gradually by extensively
Application.
The GIS high voltage distribution installation of layout single-row for bus single-subsection, in order to avoid overhead transmission line intersects, need to be by electricity
Source is arranged on same section bus with the loop of the same name of load, therefore of the same name when interval enlarging, busbar overhaul and bus-bar fault
Loop must have a power failure simultaneously, reduces power supply reliability.
As shown in Figure 1 be existing GIS power distribution equipment wiring schematic diagram, use bus single-subsection wiring shape
Formula, its GIS bus is dually arrayed, is included in the left section of bus 3M being divided axially into and left section of bus 2M, the right section of bus of bus
1M and right section of bus 2M.Connected by sectioning 6 between right section of bus 1M and left section of bus 3M two sections, bus 2M and right section of mother
Bus bar connector is all used to connect between line 1M and left section of bus 3M.Between left section of bus 3M and bus 2M, and right section of bus
Main transformer attachment means 7, bus equipment 8, bus bar connector 16 it is connected between 1M and bus 2M, two loops of the same name, wherein
Being loop 1,2 of the same name on left section of bus 3M and left section of bus 2M, loop 1 of the same name includes two transmission line circuits 1A, 1B, of the same name time
Road 2 includes two transmission line circuits 2A, 2B.Right section of bus 2M and the set-up mode of right section of bus 1M and left section of above-mentioned bus 2M and a left side
The set-up mode of section bus 3M is identical, repeats no more.
Now the line arrangement being connected on left section of bus 3M and left section of bus 2M is described in detail, loop 1 of the same name
Article two, transmission line circuit 1A, 1B are adjacently positioned, and two transmission line circuits 2A, the 2B in loop 2 of the same name are the most adjacently positioned.Although this layout
Form disclosure satisfy that general power supply reliability requirement, but still there is the shortcoming reducing power supply reliability under special circumstances:
(1) when high voltage distribution installation outlet power supply, power load distributing inequality, if left section of bus 3M, left section of bus 2M are load entirely, bus
Right section, right section bus 1M of 2M is power supply entirely, then its bus running manner is the most dumb；(2) when bus-bar fault or the maintenance of same section
Or during the new loop of enlarging, interval, loop of the same name must have a power failure, reduce power supply reliability simultaneously.The reason causing the problems referred to above exists
In: loop of the same name is mounted in identical double-bus, as transmission line circuit 1A, the 1B in loop of the same name be all connected on right section of bus 1M and
On left section of bus 3M, and loop of the same name is arranged on different two section bus, as transmission line circuit 1A is connected on right section of bus 1M
With on left section of bus 3M, transmission line circuit 1B is connected on right section of bus 1M and bus 2M, the most necessarily causes overhead transmission line scissors crossing,
Cause constructional difficulties and bring potential safety hazard to operation, and adding construction investment.
Summary of the invention
The invention provides the bus solid arrangement of a kind of bus single-subsection power distribution equipment, make aerial line of the same name
Road, power supply in different sections, can make again circuit not intersect leap, it is simple to keep in repair and extend work from load loop reasonable distribution
The construction of journey.
The bus solid arrangement of bus single-subsection power distribution equipment of the present invention, is provided with GIS including at least two and joins
The loop of the same name of electric installation, by sectioning parallel join upper strata bus and lower floor's bus, median generatrix is divided by bus bar connector
Not and upper strata bus and lower floor's bus parallel join；The upper strata outlet being provided with loop of the same name between median generatrix and upper strata bus is returned
Road, is provided with lower floor's transmission line circuit in loop of the same name, and loop of the same name respective up/down layer outlet between median generatrix and lower floor's bus
Loop is positioned on the same section of up/down layer bus.By above-mentioned arrangement, overhead transmission line of the same name, power supply not only can be made
From load loop reasonable distribution in different sections, make circuit not intersect leap, meet industry regulation, so that power supply
Safety and reliability greatly improves, and the bus arranged by upper and lower two-layer, makes to account for that scene is long-pending saves half, significantly
Degree decreases cost of investment, and is also easily accessible for service the construction with extension project.
The arrangement that one of which is concrete is, between described median generatrix and lower floor's bus arrange lower floor's transmission line circuit with
The supporting structure of upper strata bus is lower outlet framework, and lower floor's transmission line circuit is connected with the lower outlet of lower outlet framework；Described
Upper strata transmission line circuit be upper outlet framework with frame structure post, and the upper outlet of upper strata transmission line circuit and upper outlet framework is even
Connect.The fixed frame that so can utilize up/down layer bus itself to greatest extent carries out outlet connection, need not arrange extra or
Individually outlet structure.
Further, in order to prevent thunder intrusion, upper strata transmission line circuit and lower floor's transmission line circuit one of them
Being provided with lightning arrester, preferably upper strata transmission line circuit and lower floor's transmission line circuit is equipped with lightning arrester, such as, can be that AIS takes shelter from the thunder
Device, can sufficiently ensure equipment safety.According to the actual requirements lightning arrester can also be arranged in GIS.
The bus solid arrangement of the bus single-subsection power distribution equipment of the present invention, it is possible to make overhead transmission line of the same name, electricity
Source is from load loop reasonable distribution in different sections, and circuit does not intersect leap, makes the safety and reliability of power supply obtain
It is greatly improved, it is simple to maintenance and the construction of extension project, and by bus cloth in the way of upper and lower two-layer of different sections
Put, make to account for that scene is long-pending saves half, drastically reduce the area cost of investment.
Below in conjunction with the detailed description of the invention of embodiment, the foregoing of the present invention is described in further detail again.
But this should not being interpreted as, the scope of the above-mentioned theme of the present invention is only limitted to Examples below.Thinking without departing from the above-mentioned technology of the present invention
