Now the line arrangement on left section of bus 1M is described in detail, two transmission line circuit 1A, 1B phases in loop of the same name 1
Adjacent arrangement, two transmission line circuits 2A, the 2B in loop of the same name 2 are adjacently positioned.Although this arrangement form disclosure satisfy that general confession
Electric reliability requirement, but still have the shortcomings that under special circumstances to reduce power supply reliability：(1) when high voltage distribution installation outlet
When power supply, power load distributing are uneven, such as bus 1M is load, and bus 2M is power supply, then its bus running manner is extremely dumb；(2)
As loop of the same name is mounted on same bus, two transmission line circuits 1A, the 1B in the loop of the same name 1 in such as Fig. 1 are both connected to
On left section of bus 1M, when bus-bar fault or the maintenance or when being spaced the new loop of enlarging of same section, two outlets in loop of the same name are returned
Road must have a power failure simultaneously, reduce system power supply reliability.The reason for causing the problems referred to above is such as two by loop of the same name
Transmission line circuit is arranged on two sections of different buses, and such as transmission line circuit 1A is connected on left section of bus 1M, and another outlet is returned
Road 1B is connected on right section of bus 2M, will necessarily just form overhead transmission line scissors crossing, causes constructional difficulties and operation safety hidden
Suffer from, and increased construction investment.
Utility model content
This utility model provides a kind of bus solid arrangement of sectionalized single busbar connection power distribution equipment, makes aerial line of the same name

The construction of journey.
The bus solid arrangement of this utility model sectionalized single busbar connection power distribution equipment, including at least two be provided with GIS
The loop of the same name of power distribution equipment, also with the upper strata bus and lower floor's bus connected by sectioning, upper strata bus is provided with
The upper strata transmission line circuit in loop of the same name, lower floor's bus are provided with lower floor's transmission line circuit in loop of the same name, and loop of the same name is respective
Up/down layer transmission line circuit is located on the same section of up/down layer bus.By above-mentioned arrangement, frame of the same name can be not only made
Ceases to be busy road, power supply make circuit not intersect leap from load loop reasonable distribution in different sections, meet industry regulation, by
This causes the safety and reliability powered to greatly improve, and the bus arranged by upper and lower two-layer, makes to account for scene product saving
Half, drastically reduce the area cost of investment, and is also easily accessible for service the construction with extension project.
The specific arrangement of one of which is the lower floor's transmission line circuit arranged on lower floor's bus 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；What is arranged on the bus of upper strata is upper
Layer transmission line circuit is with frame structure post as upper outlet framework, and upper strata transmission line circuit is connected with the upper outlet of upper outlet framework.
So outlet connection can be carried out using the fixed frame of up/down layer bus itself to greatest extent, it is extra or single without arranging
Only outlet structure.
Further, in order to prevent thunder intrusion, one of upper strata transmission line circuit and lower floor's transmission line circuit
