Description
Technical field
The present invention relates to a kind of flexible direct current converter station transformer valve side bus collector-shoe gear and method, it is suitable for becoming
Power station and converter station converter transformer valve-side confluence；Belong to project of transmitting and converting electricity design and construction technical field.
Background technique
Converter power transformer is one of key equipment of converter station, it connects net side and valve side.The change of current of high voltage large capcity
It is independently installed that transformer generally presses three-phase phase-sequence split-phase, and using Y/ △ type connection, therefore valve side needs just to can enter by confluence
Valve hall；Arrangement of the above design scheme in converting plant or Inverter Station is consistent.
Traditional valve side bus converges method, be all it is female in ground installation three-phase collecting pipe, as shown in Figure 1, phase and phase it
Between keep certain insulating safety distances, near a phase pipe mother of transformer and transformer keep certain insulation safety away from
From, therefore occupied area is very big, the high construction cost of converter station.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, provide it is a kind of it is improved, soil can be greatly improved
Ground utilization rate has flexible direct current converter station transformer valve side bus collector-shoe gear and method compared with high universalizable and flexibility.
The purpose of the present invention is what is completed by following technical solution, a kind of flexible direct current converter station transformer valve side bus
Collector-shoe gear, it mainly includes converter power transformer, collecting pipe is female and overcast, the converter power transformer are that split-phase is independently pacified
Converter power transformer fill, using Y/ △ type, the converter power transformer carry out three-phase confluence and are simultaneously connected to valve hall, the remittance
Flow tube mother is suspended in midair in the sky using overcast；The bus rod is built on stilts installation；By transformer equipment and bus rod
Layered arrangement can make full use of space, greatly save converter station occupied area, and save the cost improves economy.
A kind of bus confluence method using the flexible direct current converter station transformer valve side bus collector-shoe gear, it is described
Bus confluence method includes: to set up an overcast, collecting pipe mother is fixedly mounted on bracket, transformer value side bushing goes out
It is female that line according to phase number is connected to wherein two root canals, every phase pipe mother stock not Hui Liu after draw by arrester, mutual inductor and be connected to valve hall.
Compared with traditional scheme, the present invention is conducive to greatly save occupied area, effectively improves land utilization ratio, and saving is changed
Stream station construction cost, improves the economy of design scheme.
Detailed description of the invention
Fig. 1 is traditional collecting pipe mother's installation method schematic diagram.
Fig. 2 is the floor map of collecting pipe mother installation method of the present invention.
Fig. 3 is the sectional schematic diagram of collecting pipe mother installation method of the present invention.
Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings: shown in Fig. 2, a kind of flexible direct current converter station transformer valve
Side bus collector-shoe gear, it is mainly concerned with converter power transformer 1 and collecting pipe mother 2 and overcast 3, the converter power transformer
1 is that split-phase is independently installed, using Y/ △ type wiring, it is therefore desirable to carry out three-phase confluence and be connected to valve hall, the confluence again
Pipe mother 2 sees side on the transformer using the installation of overcast 3 in the sky, in cross-section diagram, sees have with transformer equipment on plan view
It is overlapped.
The bus converges (see Fig. 2, by taking A phase as an example), and converter transformer valve-side sleeve has 2 outlets a, x, is respectively connected to
The A phase of A, C phase of collecting pipe mother, collecting pipe mother accesses valve hall using equipment such as arrester, mutual inductors.The aerial peace
Dress, is shown in Fig. 2, Fig. 3, the space installation site of three-phase collecting pipe mother completely on the transformer just, near transformer a phase from
Plan view sees the surface in transformer, different from conventional mounting location (see figure 1).
A kind of to utilize above-mentioned flexible direct current converter station transformer valve side bus confluence method, bus rod installation method is such as
Under:
A) overcast is set up, collecting pipe mother is fixedly mounted on bracket；
B) it is female according to phase number to be connected to wherein two root canals for the outlet of transformer value side bushing, then every phase pipe mother stock not Hui Liu after by keeping away
The devices such as thunder device, mutual inductor, which draw, is connected to valve hall.
Embodiment:
This bus rod of the invention uses built on stilts installation method, can be sufficiently sharp by transformer equipment and bus rod layered arrangement
With space, converter station occupied area is greatlyd save, is reducingd the construction costs, improves economy.
The present invention refers mainly to the optimization of valve side bus rod installation site.
The valve side bus rod installation site optimization refers to the surface-mounted collecting pipe mother of tradition, integrally moves to sky
In, using overcast, the horizontal relative position in vertical direction is determined by the safe distance of bracket and transformer, as far as possible cloth
It sets compact.From construction angle, as soon as more installation overcasts are only needed, it can be mobile by the biggish bus rod of script occupied area
To aerial, project amount is smaller, occupied area can be greatly saved while not influencing to converge effect.
Compared with traditional scheme, such as Fig. 1,6.5 meters of three-phase bus rod phase and phase interval, near a phase pipe of transformer
Female and transformer bay is every 6.5, then about 19.5 meters of total distance；Flexible direct current converter station transformer valve side bus confluence of the present invention
Method, such as Fig. 2, total distance only have 8.5 meters, and lateral distance saves ten meters or more, are conducive to greatly save occupied area, improve
Land utilization ratio saves converter station construction cost.
The present invention is expounded the principle of the present invention and embodiment by embodiments above, the above implementation
The explanation of example is merely used to help understand method and core concept of the invention；The contents of the section should not be construed as to of the invention
Limitation.
