The invention relates to a bus three-dimensional arraignment structure for a dual-bus dual-segment power distribution device. The bus three-dimensional arrangement structure comprises at least two same-name loops provided with GIS (Gas Insulated Switchgear) power distribution devices, and an upper-layer bus and a lower-layer bus which are connected in parallel in four columns through a segmenting device, wherein upper-layer outgoing loops of the same-name loops are arranged on the upper-layer bus; lower-layer outgoing loops of the same-name loops are arranged on the lower-layer bus; the upper/lower-layer outgoing loops of the same-name loops are positioned on the same section of the upper/lower-layer buses. By adopting the bus three-dimensional arraignment structure for the dual-bus dual-segment power distribution device, same-name overhead lines, a power supply and a load loop are reasonably allocated to different segments, line intersection and crossing are avoided, the power supply safety and reliability are enhanced greatly, and convenience is brought to construction of repair and extension projects; moreover, buses on different segments are arranged in upper and lower layers, so that the floor area is saved by a half, and the investment cost is lowered greatly.
Description
Technical field
The present invention relates to the arrangement in the overhead outlet loop of the same name in gis high voltage distribution installation, it is concretely double
The bus solid arrangement of the double segmentation power distribution equipment of bus.
Background technology
In high voltage distribution installation, gas-insulating and fully-enclosed power distribution equipment (gis) and in the past conventional air-insulated routine
Power distribution equipment (ais) is compared, and has the advantages that floor space is little, safety reliability is high, maintenance workload is little, gradually extensive
Application.
For the gis high voltage distribution installation of the double single-row arrangement of segmentation of double-bus, 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 in interval enlarging, busbar overhaul and bus-bar fault
Loop must have a power failure simultaneously, reduces power supply reliability.
As shown in Fig. 1 existing gis power distribution equipment wiring schematic diagram, connection type is the double segmentation of double-bus, and its gis joins
The double-bus of electric installation is bus dually arrayed side by side, including in left section of double-bus 3m, 4m being divided axially into of bus and right section
Double-bus 1m, 2m, is connected using sectioning 6 between two sections of left and right.Main transformer is connected on the double-bus of two sections of left and right even
Connection device 7 and bus equipment 8.Two loops 1,2 of the same name are wherein connected with left section of double-bus 3m, 4m, loop 1 of the same name includes
It is provided with the loop 1a and loop 1b in gis power distribution equipment loop of the same name 1, loop 2 of the same name also includes being provided with gis power distribution equipment together
Name loop 2a and loop 2b, right section of double-bus 1m, 2m is identical with the set-up mode of left section of double-bus 3m, 4m, repeats no more.
Now the line arrangement in left section of double-bus 3m, 4m is described in detail, two transmission line circuits in loop 1 of the same name
1a, 1b's is adjacently positioned, and two transmission line circuits 2a, the 2b in loop 2 of the same name are also adjacently positioned.Although this arrangement form can be expired
The general power supply reliability of foot requires, but still haves the shortcomings that under special circumstances to reduce power supply reliability: (1) is press-fitted when height
When electric installation outlet power supply, power load distributing are uneven, such as bus 1m, 2m is load entirely, and bus 3m, 4m are power supply entirely, then its bus
The method of operation is extremely dumb；(2) because loop of the same name is mounted in same double-bus, such as two of the loop of the same name 1 in Fig. 1
Transmission line circuit 1a, 1b are both connected in left section of double-bus 3m, 4m, when bus-bar fault or maintenance or new the returning of interval enlarging of same section
Lu Shi, two transmission line circuits in loop of the same name must have a power failure simultaneously, reduces system power supply reliability.The reason cause the problems referred to above
It is and as two transmission line circuits in loop of the same name are arranged on different two section bus, such as transmission line circuit 1a is connected to
In left section of double-bus 3m, 4m, another transmission line circuit 1b is connected in right section of double-bus 1m, 2m, just necessarily forms overhead transmission line
Scissors crossing, causes constructional difficulties and brings potential safety hazard to operation, and increased construction investment.
