Description
Technical field
The present invention relates to power equipment arrangement and framework, specifically a kind of brace type bus arranges knot back-to-back
Structure.
Background technology
The low-pressure side of the 500kV main transformers currently run, using single bus scheme mode；Consider the reliable of bus mounting means
Property, bus typically uses horizontal arranging mode.To improve the reliability of main transformer low-pressure side wiring, run and repeatedly require that setting is total disconnected
Road device.
If main transformer low-pressure side sets main breaker, its mode of connection is changed into bus rod and master from single bus scheme
Bus combines wiring.It is horizontally disposed in view of bus rod and safety net distance during main bus-bar difference during interruption maintenance, and bus
Phase spacing, horizontally disposed using routine can make the increase of transformer station area, can not meet that the place limitation in universal design will
Ask, also runed counter to the theory of saving the area.
At present, the conventional form of bus bars of open type distribution device has following three kinds outside room：Soft bus, hanging tubular bus and
Brace type pipe bus.Soft bus anti-seismic performance is good, but bus sag and windage yaw displacement are larger, larger to framework level pulling force,
And floor space is larger；Pipe bus sag is small, and phase spacing is small, smaller to the horizontal pull of framework, and floor space is relatively fewer,
Wherein brace type pipe bus structure is highly low, is easy to construct, safeguards, but antidetonation and wind resistance are poor；And suspension type bus resists
Shock stability is good, but bus framework is high, and construction, maintenance difficulties are larger.
It is arranged vertically according to bus, change plane is space, then shortens the horizontal range of busbar arrangement, and can be in main transformer
Low-pressure side sets main breaker, and meets that the place limitation of universal design requires, but in the case where bus is arranged vertically, it is each mutually in same
One vertical plane, in sleety weather, easily in adjacent alternate formation water column, cause phase fault, cause network system failure.
Arranged according to bus horizontal steps, in same bus, adjacent level is alternate to be staggeredly arranged, then can solve sleet
Weather phase fault problem, and it is space to change plane, shortens the horizontal range of busbar arrangement；But arranged in bus horizontal steps
Under, bus is larger to the active force of insulator or framework, easily causes that bus framework is unstable, influences the safety fortune of transformer station
OK, consolidation process need to be taken to framework.
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 brace type is female
The back-to-back arrangement of line, it changes plane with space, and conventional levels arrangement or vertically arranged bus are optimized on back-to-back
The bus of middle lower supporting type step arrangement, bus is reduced to insulator or the active force of framework, while cause in same bus
It is adjacent it is alternate be staggeredly arranged, to avoid that phase fault occurs under sleety weather；In addition, the arrangement causes in existing main transformer
And idle place can arrange two buses of bus rod and main bus-bar, power distribution equipment is arranged to it is more compact, reach saving take up an area
Mesh.
Therefore, the present invention adopts the following technical scheme that：The back-to-back arrangement of brace type bus, including it is vertically disposed
Steel pipe pole, horizontally disposed horizontal cross-arm, horizontal bus rod and main bus-bar,
The both sides of the steel pipe pole are using three layers of horizontal cross-arm different in size of setting, and in horizontal cross-arm-end in back-to-back fashion
Portion sets the support insulator of bus respectively；
The support insulator arranges that described bus rod is arranged in steel by support insulator ladder perpendicular to horizontal cross-arm
The side of tube rod, main bus-bar are arranged in the opposite side of steel pipe pole by support insulator ladder.
As further improving and supplementing to above-mentioned technical proposal, the present invention takes following technical measures：
In same bus, adjacent alternate horizontal range is 0.4-0.6 rice, and vertical range is 1.7-2.0 rice, and ladder is arranged from top to bottom
Row, ensure alternate safe distance, meet the minimum electrical distance of Insulation Coordination requirement.
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 highly preferred of the support insulator is 0.5-0.7 rice.
The length of the horizontal cross-arm is respectively 2.3-2.5 rice, 1.9-2.1 rice, 1.5-1.7 rice from top to bottom.
The bus rod and main bus-bar use tube type bus, and both are respectively 4.0- from top to down with the spacing of phase
4.2 meters, 3.2-3.4 rice, 2.4-2.6 rice.
Conventional levels arrangement or vertically arranged bus are optimized for back-to-back upper, middle and lower brace type step arrangement by the present invention
Bus, reduce conventional levels ladder arrange Down Highway to insulator or the active force of framework, improve shelf stability；Keep away
Exempt from the phase fault of sleety weather, improve reliability, it is safe for operation to be maked an inspection tour conveniently with operation, easy access and installation, reduce
Personnel put into, and improve benefit safe for operation；Enable and arrange bus rod and main bus-bar two in existing main transformer and idle place
Bar bus, power distribution equipment is arranged to more compact, has been reached the mesh saved and taken up an area, three materials input has been saved, so as to being greatly reduced
Cost.
