Description
Technical field
This utility model relates to power equipment arrangement and framework, specifically single-column double-bus vertical cloth back-to-back
Put structure.
Background technology
Along with the development of electrical network, substation equipment quantity is being continuously increased, land reserved resources wretched insufficiency, and site is levied
Ground, removal expense increase day by day, and especially at some urban central zones, land expropriation cost is in substantially rising situation, substation location
Selecting more and more difficulty, it is current problem demanding prompt solution that substation equipment is saved the area.
The low-pressure side of the current 500kV main transformer run, uses single bus scheme mode, simply clear in its wiring of reservation,
Equipment is few, easy to operate, it is simple on the basis of extending and using the advantages such as complete power distribution equipment, for improving main transformer low-pressure side wiring
Reliability, runs and repeatedly requires to arrange main breaker, but owing to the place by universal design is limited, it is impossible to main transformer low pressure is set
The main breaker of side.
On main transformer low-pressure side bus arrangement, it is considered to the reliability of bus mounting means, typically adopt both at home and abroad at present
Use bus horizontal arranging mode.Bus divides again soft bus and pipe bus two kinds.The bus shape that outside room, open type distribution device is conventional
Formula has following three kinds: soft bus, hanging tubular bus and brace type pipe bus.
Soft bus: be characterized in that anti-seismic performance is good, but wire is relatively big to the horizontal pull of framework, and bus sag is relatively big, wind
Bias placement is big, and floor space is relatively big, the most less application.
Brace type pipe bus: compared with soft bus, the sag of brace type pipe bus is little, phase spacing is little, insulator chain pair
The horizontal pull of framework is less, and under the effect of wind-force and short-circuit electromotive force, pipe bus lateral displacement is little, and arranges clearly, frame
Structure simplifies, and floor space is relatively fewer, owing to bus structure height is low, saves steel, is conducive to constructing, run and safeguarding, but
Antidetonation and wind resistance are poor, thus this layout be the most often applied to non-high yield, many people is few, earthquake intensity is low (7 degree and with
Under), area that wind speed is little.
Hanging tubular bus: have that bus sag is little, phase spacing is little, insulator chain is less to the horizontal pull of framework,
Under the effect of wind-force and short-circuit electromotive force, pipe bus lateral displacement is little, and layout is neat, clear, take up an area the advantages such as relatively fewer.
Owing to hanging tubular bus is that insulator chain is suspended on bus gate framework by insulator chain suspended fixing by tubular bus
On, general employing V type tiltedly hangs the mode directly hung with V type, and compared with brace type pipe bus, suspension bus has the most anti-
Shock stability, but bus framework is high, uses insulator chain quantity many, and cost is high, construct, run, maintenance difficulties and workload relatively big,
Therefore the area that this form is generally used for earthquake intensity high (8 degree and more than), wind speed is big.
At present state's net 500kV optional mode of connection of main transformer low-pressure side bus, the complicated and simple degree of wiring, equipment use investment,
The aspects such as floor space and enlarging compatibility are all respectively arranged with pluses and minuses, are meeting the aspects such as reliability, motility and economy also
In urgent need to be improved.
Utility model content
Technical problem to be solved in the utility model is the defect overcoming above-mentioned prior art to exist, it is provided that a kind of single-column
Double-bus is arranged vertically structure back-to-back, and it changes plane with space, in being optimized for the most above by the bus that conventional levels is arranged
The bus of lower arrangement so that bus rod and two buses of main bus-bar can be arranged at existing main transformer and idle place, by distribution
Device is arranged to more compact, reaches to save the mesh ground taken up an area.
To this end, this utility model adopts the following technical scheme that: single-column double-bus is arranged vertically structure back-to-back, including hanging down
Straight steel pipe pole, bus rod and the main bus-bar arranged,
The both sides of described steel pipe pole use in back-to-back fashion to arrange the support insulator of bus, and this support insulator is water
Plain cloth is put, and described bus rod is arranged vertically on the side of steel pipe pole by support insulator, and main bus-bar passes through post insulator
Son is arranged vertically on the opposite side of steel pipe pole.
As improving further and supplementing technique scheme, this utility model takes techniques below measure:
In same bus, adjacent phase spacing is 2-2.5 rice, arranges from top to bottom, it is ensured that alternate safe distance, meets
The minimum electrical distance that Insulation Coordination requires.
Chopper it is provided with between disconnecting switch and current transformer.The reliability of wiring is improved by chopper, maximum
Degree avoids the problem in large-engineering transformation and lectotype selection specification standards, makes an inspection tour consequently facilitating run safety with operation, inspection
Repair and install simple, save three material cost and costs.
Described bus rod uses copper bar to be connected with xegregating unit, between xegregating unit and chopper and chopper and electric
Flexible circuit conductor is used to connect between current transformer.
The width of described support insulator is preferably 1.4-1.6 rice.
Described bus rod and main bus-bar all use tube type bus, and both spacing are 2.9-3.1 rice.
The bus that conventional levels is arranged is optimized for the bus of back-to-back upper, middle and lower arrangement by this utility model so that existing
Main transformer and idle place can arrange bus rod and two buses of main bus-bar, power distribution equipment is arranged to more compact, reaches
Save the mesh ground taken up an area, save three materials and put into, thus cost is greatly reduced；Improve reliability, run safety and operation tour side
Just, it is simple to overhaul and install, reduce personnel and put into, improve and run safety benefit.
