Abstract
The invention relates to a busbar three-dimensional layout structure of single busbar segmented power distribution unit, comprising at least two same loops set with GIS power distribution unit as well as continuous upper and lower busbars passing through the segmented unit. The upper outlet loop of the same loop is set in the upper busbar, the lower outlet loop of the same loop is set in the lower busbar and respective upper/ lower outlet loops of the same loops are located in the same section of upper/lower busbars. The busbar three-dimensional layout structure of single busbar segmented power distribution unit in the invention enables the reasonable distribution of same overhead circuit, power source and load loop in the different segments. Non-mutual junction and crossing of circuit make the safety and reliability of power supply improve largely for the convenience of maintenance and construction of extension project, and the arrangement of busbars in different segments by upper layer and lower layer saves half afield-occupation area and greatly reduces the investment cost.
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 single
The bus solid arrangement of bus section 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 floor space little, and security reliability is high, the advantages such as maintenance workload is little, gradually extensively should
With.
At the GIS high voltage distribution installation of traditional single busbar list step-by-step arrangement, 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, connection type is single busbar list step-by-step arrangement, its
The single busbar of GIS power distribution equipment, for be axially arranged side by side along bus, is included in the left section of bus 1M being divided axially into and the right side of bus
Section bus 2M, uses sectioning 6 to connect between the bus of two sections, left and right.Two sections, left and right bus is connected to main transformer connect
Device 7 and bus equipment 8.Wherein connecting on left section of bus 1M and have two loops 1,2 of the same name, loop 1 of the same name includes GIS and joins
The loop 1A and loop 1B in electric installation loop of the same name 1, loop 2 of the same name also includes being provided with GIS power distribution equipment loop 2A and loop
2B, right section of bus 2M is identical with the set-up mode of left section of bus 1M, repeats no more.
Now the line arrangement on left section of bus 1M is described in detail, two transmission line circuit 1A, 1B phases in loop 1 of the same name
Adjacent layout, two transmission line circuits 2A, the 2B in loop 2 of the same name are adjacently positioned.Although this arrangement form disclosure satisfy that general confession
Electricity reliability requirement, but still there is the shortcoming reducing power supply reliability under special circumstances: (1) is when high voltage distribution installation outlet
When power supply, power load distributing inequality, if bus 1M is load, bus 2M is power supply, then its bus running manner is the most dumb；(2)
Owing to loop of the same name is mounted on same bus, two transmission line circuits 1A, 1B such as the loop of the same name 1 in Fig. 1 are both connected to
On left section of bus 1M, when the bus-bar fault of same section or maintenance or the new loop of interval enlarging, two outlets in loop of the same name are returned
Road must have a power failure simultaneously, reduces system power supply reliability.The reason causing the problems referred to above is as will be by the two of loop of the same name
Transmission line circuit is arranged on different two section bus, as being connected to by transmission line circuit 1A on left section of bus 1M, another outlet is returned
Road 1B is connected on right section of bus 2M, just will necessarily form overhead transmission line scissors crossing, causes constructional difficulties and runs the most hidden
Suffer from, and add construction investment.
Summary of the invention
The invention provides the bus solid arrangement of a kind of sectionalized single busbar connection power distribution equipment, make overhead transmission line of the same name,
Power supply in different sections, can make again circuit not intersect leap from load loop reasonable distribution, it is simple to maintenance and extension project
Construction.
The bus solid arrangement of sectionalized single busbar connection power distribution equipment of the present invention, is provided with GIS distribution including at least two
The loop of the same name of device, also has the upper strata bus and lower floor's bus connected by sectioning, and upper strata bus is provided with of the same name
The upper strata transmission line circuit in loop, lower floor's bus is provided with lower floor's transmission line circuit in loop of the same name, and the respective up/down in loop of the same name
Layer transmission line circuit is positioned on the same section of up/down layer bus.By above-mentioned arrangement, aerial line of the same name not only can be made
Road, power supply in different sections, make circuit not intersect leap from load loop reasonable distribution, meet industry regulation, thus make
The safety and reliability that must power greatly improves, and the bus arranged by upper and lower two-layer, makes to account for that scene is long-pending saves one
Half, drastically reduce the area cost of investment, and be also easily accessible for service the construction with extension project.
The arrangement that one of which is concrete is, lower floor's transmission line circuit that lower floor's bus is arranged is with the supporting of upper strata bus
Structure is lower outlet framework, and lower floor's transmission line circuit is connected with the lower outlet of lower outlet framework；Arrange on the bus of upper strata is upper
Layer transmission line circuit is upper outlet framework with frame structure post, and upper strata transmission line circuit is connected with the upper outlet of upper outlet framework.
The fixed frame that so can utilize up/down layer bus itself to greatest extent carries out outlet connection, need not arrange extra or single
Only 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 different actual demands, it is also possible to lightning arrester is arranged in GIS.
The bus solid arrangement of the sectionalized single busbar connection power distribution equipment of the present invention, it is possible to make overhead transmission line of the same name, power supply
From load loop reasonable distribution in different sections, circuit does not intersect leap, makes the safety and reliability of power supply obtain greatly
The raising of amplitude, it is simple to maintenance and the construction of extension project, and the bus of different sections is arranged in the way of upper and lower two-layer,
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
