Description
Technical field
The utility model is related to power equipment arrangement and framework, specifically a kind of back-to-back cloth of brace type busbar
Set structure.
Background technology
The low-pressure side of currently running 500kV main transformers, using single bus scheme mode；Consider the reliable of busbar mounting means
Property, busbar generally uses horizontal arranging mode.To improve the reliability of main transformer low-pressure side wiring, runs and repeatedly require setting total disconnected
Road device.
If main breaker is arranged in main transformer low-pressure side, the mode of connection is changed into bus rod and master from single bus scheme
Busbar combines wiring.Safety net distance and busbar when in view of bus rod and main bus-bar difference when interruption maintenance is horizontally disposed
Phase spacing, using it is conventional it is horizontally disposed substation's area can be made to increase, cannot be satisfied the limitation of the place in universal design and want
It asks, is also runed counter to the theory of saving the area.
Currently, the common form of bus bars of open type distribution device has following three kinds outside room：Soft busbar, hanging tubular bus and
Brace type pipe busbar.Soft busbar anti-seismic performance is good, but busbar arc sag and windage yaw displacement are larger, larger to framework level pulling force,
And floor space is larger；Pipe busbar arc 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 height is low, convenient for construction, safeguards, but antidetonation and wind resistance are poor；And suspension type busbar is anti-
Shock stability is good, but busbar framework is high, and construction, maintenance difficulties are larger.
It is arranged vertically according to busbar, change plane is space, then shortens the horizontal distance of busbar arrangement, and can be in main transformer
Main breaker is arranged in low-pressure side, and the place limitation for meeting universal design requires, but in the case where busbar is arranged vertically, each mutually in same
One vertical plane is easy, in adjacent alternate formation water column, to cause phase fault, cause network system failure in rain and snow.
It is arranged according to busbar horizontal steps, in same busbar, 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 distance of busbar arrangement；But it is arranged in busbar horizontal steps
Under, busbar is larger to the active force of insulator or framework, be easy to cause that busbar framework is unstable, influences the safety fortune of substation
Row, need to take consolidation process to framework.
Utility model content
Technical problem to be solved in the utility model is to overcome the problems of the above-mentioned prior art, provides a kind of support
The back-to-back arrangement of formula busbar, plane is changed with space, and conventional levels arrangement or vertically arranged busbar are optimized for leaning against
The busbar of lower supporting type step arrangement in back reduces active force of the busbar to insulator or framework, while making same mother
In line it is adjacent it is alternate be staggeredly arranged, to avoid phase fault occurs under sleety weather；In addition, the arrangement makes existing
Main transformer and idle place can arrange two busbares of bus rod and main bus-bar, power distribution equipment is arranged to more compact, reach saving
The mesh of occupation of land.
For this purpose, the utility model adopts the following technical scheme：The back-to-back arrangement of brace type busbar, including vertically set
Steel pipe pole, horizontally disposed horizontal cross-arm, horizontal bus rod and the main bus-bar set,
The both sides of the steel pipe pole use is arranged three layers of horizontal cross-arm different in size in back-to-back fashion, and horizontal horizontal
The support insulator of busbar is respectively set in load end；
The support insulator arranges that the bus rod is arranged by support insulator ladder perpendicular to horizontal cross-arm
In the side of steel pipe pole, main bus-bar is arranged in the other side of steel pipe pole by support insulator ladder.
As further improving and supplementing to above-mentioned technical proposal, the utility model takes following technical measures：
In same busbar, adjacent alternate horizontal distance is 0.4-0.6 meters, and vertical range is 1.7-2.0 meters, from top to bottom rank
Ladder arrangement, ensures alternate safe distance, meets the minimum electrical distance of Insulation Coordination requirement.
Breaker is equipped between disconnecting switch and current transformer.The reliability of wiring is improved by breaker, it is maximum
Degree avoids the problem in large-engineering transformation and lectotype selection specification standards, consequently facilitating operational safety and operation are maked an inspection tour, inspection
It repaiies and simple to install, saves three material costs and cost.
The bus rod is connect using copper bar with disconnecting switch, between disconnecting switch and breaker and breaker with electricity
It is connected using flexible circuit conductor between current transformer.
The highly preferred of the support insulator is 0.5-0.7 meters.
The length of the horizontal cross-arm is respectively 2.3-2.5 meters, 1.9-2.1 meters, 1.5-1.7 meters from top to bottom.
The bus rod and main bus-bar are all made of tube type bus, and the two is respectively 4.0- from top to down with the spacing of phase
4.2 meters, 3.2-3.4 meters, 2.4-2.6 meters.
The utility model arranges conventional levels or vertically arranged busbar is optimized for back-to-back upper, middle and lower brace type ladder
The busbar of arrangement reduces active force of the conventional levels ladder arrangement Down Highway to insulator or framework, improves framework stabilization
Property；The phase fault of sleety weather is avoided, reliability is improved, it is convenient that operational safety is maked an inspection tour with operation, easy access and installation,
Reduction personnel put into, and improve operational safety benefit；Enable and arranges bus rod and main mother in existing main transformer and idle place
Line two busbares, power distribution equipment are arranged to more compact, have been reached the mesh saved and taken up an area, three materials input have been saved, to substantially
Reduce cost.
