Description
Technical field
The present invention relates to power equipment arrangement and framework, specifically single-column double-bus is arranged vertically knot back-to-back
Structure.
Background technology
With the development of power network, substation equipment quantity is being continuously increased, land reserved resources wretched insufficiency, site sign
Ground, removal expense increasingly increase, and especially rise situation, substation location in obvious in some urban central zones, land expropriation cost
Selection is more and more difficult, and it is current urgent problem to be solved that substation equipment, which is saved the area,.
The low-pressure side of the 500kV main transformers currently run, using single bus scheme mode, retain its wiring it is simple it is clear,
Equipment is few, easy to operate, be easy to extend and using the advantages that complete power distribution equipment on the basis of, to improve main transformer low-pressure side wiring
Reliability, run and repeatedly require to set main breaker, but because the place by universal design is limited, main transformer low pressure can not be set
The main breaker of side.
In main transformer low-pressure side busbar arrangement mode, consider the reliability of bus mounting means, typically adopt both at home and abroad at present
With bus horizontal arranging mode.Bus is divided to soft two kinds of bus and pipe bus again.The conventional bus shape of open type distribution device outside room
Formula has following three kinds：Soft bus, hanging tubular bus and brace type pipe bus.
Soft bus：It is characterized in that anti-seismic performance is good, but wire is larger to the horizontal pull of framework, and bus sag is larger, wind
Bias placement is big, and floor space is larger, at present less application in design.
Brace type pipe bus：Compared with soft bus, the sag of brace type pipe bus is small, phase spacing is small, insulator chain pair
The horizontal pull of framework is smaller, and in the presence of wind-force and short-circuit electromotive force, pipe bus lateral displacement is small, and arranges clear, frame
Structure simplifies, and floor space is relatively fewer, because bus structure is highly low, saves steel, is advantageous to construct, run and safeguard, but
Antidetonation and wind resistance are poor, thus the arrangement be now often applied to non-high yield, more people are few, earthquake intensity is low（7 degree and with
Under）, the small area of wind speed.
Hanging tubular bus：With bus sag is small, phase spacing is small, insulator chain is smaller to the horizontal pull of framework,
The advantages that in the presence of wind-force and short-circuit electromotive force, pipe bus lateral displacement is small, and arrangement is neat, clear, occupation of land is relatively fewer.
Because hanging tubular bus is by insulator chain suspended fixing by tubular bus, insulator chain is suspended on bus gate framework
On, typically by the way of V types are tiltedly hung and V types are directly hung, compared with brace type pipe bus, suspension type bus has preferably anti-
Shock stability, but bus framework is high, and more using insulator chain quantity, cost is high, and construction, operation, maintenance difficulties and workload are larger,
Therefore the form is generally used for earthquake intensity height（8 degree and more than）, the big area of wind speed.
At present state net the optional mode of connection of 500kV main transformer low-pressure side buses, the complicated and simple degree of wiring, equipment using investment,
Floor space and enlarging compatibility etc. all respectively have advantage and disadvantage, are meeting reliability, flexibility and economy etc. also
It is in urgent need to be improved.
The content of the invention
The technical problems to be solved by the invention are the defects of overcoming above-mentioned prior art to exist, there is provided a kind of single-column is double female
Line is arranged vertically structure back-to-back, and it changes plane with space, and the bus that conventional levels are arranged is optimized for into back-to-back upper, middle and lower arranges
The bus of row so that two buses of bus rod and main bus-bar can be arranged in existing main transformer and idle place, by power distribution equipment
It is arranged to more compact, reaches the mesh saved and taken up an area.
Therefore, the present invention adopts the following technical scheme that：Single-column double-bus is arranged vertically structure back-to-back, including vertically sets
Steel pipe pole, bus rod and the main bus-bar put,
Using the support insulator for setting bus in back-to-back fashion, the support insulator is in horizontal cloth for the both sides of the steel pipe pole
Put, described bus rod is arranged vertically on the side of steel pipe pole by support insulator, and main bus-bar is hung down by support insulator
The straight opposite side for being arranged in steel pipe pole.
As further improving and supplementing to above-mentioned technical proposal, the present invention takes following technical measures：
In same bus, adjacent phase spacing is 2-2.5 rice, is arranged from top to bottom, ensures alternate safe distance, meets insulation
Coordinate desired minimum electrical distance.
Breaker is provided between disconnecting switch and current transformer.The reliability of wiring is improved by breaker, it is maximum
The problem of degree is avoided in large-engineering transformation and lectotype selection specification standards, consequently facilitating safe for operation and operation is maked an inspection tour, inspection
Repair and simple to install, save three material costs and cost.
Described bus rod is connected using copper bar with xegregating unit, between xegregating unit and breaker and breaker with electricity
Connected between current transformer using flexible circuit conductor.
The width of the support insulator is preferably 1.4-1.6 rice.
The bus rod and main bus-bar use tube type bus, and both spacing are 2.9-3.1 rice.
The bus of conventional levels arrangement is optimized for the bus of back-to-back upper, middle and lower arrangement by the present invention so that in existing master
Become and idle place can arrange two buses of bus rod and main bus-bar, power distribution equipment is arranged to more compact, has reached saving
The mesh of occupation of land, three materials input is saved, so as to which cost be greatly reduced；Reliability is improved, it is safe for operation to be maked an inspection tour conveniently, just with operation
In maintenance and installation, personnel's input is reduced, improves benefit safe for operation.
