The application of 1500MVA/1000kV AC UHV Transformer can significantly improve the economy of the UHV substation, and matches well with the transmission capacity of UHV lines, which has wide prospect of application. Because of its large capacity and large volume, the whole transportation weight with nitrogen is about 470-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 1500MVA/1000kV UHV AC transformer. In order to make the products applicable to any UHV substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity UHV Transformer” as a key scientific research projects, and entrusted BTW to carry out the research.
During the process of research and development, BTW adopted the advanced design technology and modular design, the transformer can be transported disassembly and with advantages of compact core and winding body, less transportation weight and low transportation cost, effectively solves the need of UHV construction in the transportation restricted areas. By using the most advanced 3D magnetic field calculation software, BTW performed detailed analysis and calculation for the magnetic flux leakage and eddy current loss of the transformer coil, iron core and oil tank steel structures. Besides, by using of the advanced electric field calculation software, BTW performed detailed analysis and calculation of main longitudinal insulation, and mastered the arrangement of the main longitudinal insulation of large capacity UHV transformer and the control of distribution of winding magnetic flux leakage. All of which make the products with low loss, low noise, small volume, strong anti short circuit ability, no local overheating and other significant advantages, and guarantee the long-term safe and stable operation.
The world's first on-site assembled large capacity UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of 1500MVA/1000k transformer, which marks BTW has fully occupied the world transformer industry technical peak. The successful development of the product filled the gaps in the domestic technology and met the urgent need of UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.
- Q:What is the meaning of the transformer without excitation?
- General power transformers are equipped with tap-changer, can be carried out in a small range of voltage regulation to meet the grid voltage fluctuations, as far as possible to the transformer output side of the voltage stability. There are two ways:
1, on-load regulation: it can be in the transformer with load, automatic or manual tap position switch. Because the switch is completed in an instant, so it will not affect the normal operation, that is, once, the second side are not power failure can be carried out under the circumstances.
2, no excitation voltage regulator (sometimes mistakenly said no load voltage regulator): is to be in the primary side and the secondary side are power outages, put the isolation switch to open the case, to ensure that the transformer in the absence of electricity, adjust the tap position , The regulator.
3, in the past, it is possible from the English No Load (no load) or On Load (contained) translated over, said to be no load regulator. This is not accurate, it is easy to be misinterpreted as: the transformer can be in the absence of load (current) when the regulator, without the need to control whether the power side. This is very dangerous, no excitation voltage regulator, it is very accurate, to the transformer side, the secondary side are power, in the absence of any excitation circumstances, to operate.
4, therefore, our professionals must change No - Load to Off - Eirecuit - Tap - Changing.
- Q:220V to 12V transformer L N + V + V on behalf of what? The more detailed the better! Thank you prawn
- LN represents the line of fire and zero line, + V is the input and output voltage
- Q:Will the installation of transformers, power supply bureau is how the charges?
- Electricity Bureau to receive construction, survey, design, equipment, measurement fees. The plane fee for the capacity of the general 250KVA above the transformer to charge capacity fee 1KVA a month generally 25 yuan. Industrial electricity is divided into peak and valley electricity price difference, agricultural electricity regardless. Details can call me
- Q:S11-1250kVA transformer oil capacity how much
- S11-1250kVA transformer oil capacity is 550kg, the pressure of the relevant information will be marked on the nameplate, the nameplate has the relevant parameters.
- Q:Transformer cooling method AN stands for what
- The cooling mode of the transformer is determined by the cooling medium and the circulation method. Since the oil-immersed transformer is also divided into the internal cooling mode of the tank and the external cooling mode of the tank, the cooling mode of the oil-immersed transformer is represented by four letters.
The first letter: the cooling medium in contact with the winding.
O -------- mineral oil or ignition of more than 300 ℃ of insulating liquid;
K -------- Insulation liquid with ignition point greater than 300 ℃;
L -------- ignition can not be measured insulation liquid;
The second letter: the way the internal cooling medium is circulated.
N -------- The oil flow flowing through the cooling equipment and the windings is a natural thermal convection cycle;
F -------- The oil flow in the cooling equipment is forced to circulate and the oil flow flowing through the windings is the thermal convection cycle;
D -------- The oil flow in the cooling equipment is forced to circulate, at least in the main winding oil flow is forced to guide the cycle;
Third letter: external cooling medium.
A -------- air;
W -------- water;
The fourth letter: the way the external cooling medium is circulated.
N -------- natural convection;
F -------- Forced circulation (fan, pump, etc.).
Therefore, the transformer cooling method AN represents the air convection cooling method.
- Q:How do I select a transformer connection group?
- Connection group can not be arbitrarily selected, depending on the primary transformer connection group. If the higher-level transformer for the star angle, the next level on the election star angle
- Q:Transformer rated capacity 500 / 750KVA (AN / AF) What does it mean?
- Air cooling can improve so much no sure no problem, and now a lot of transformer air cooling and self cooling ratio is 100: 80, 100: 70, there are 100: 60.
- Q:50KVA transformer maximum load is how much?
- 50KVA transformer can bring the maximum load is, 1.45 * 50 = 72.5A or so
- Q:From the variable ratio to determine whether the transformer is boost or buck
- High pressure to low pressure is the buck, and vice versa is boosted. That is, the input transformer is a high voltage, the output is a low voltage is a low voltage.
- Q:What is the meaning of auxiliary transformer, sub-variable and box change
- box change is box-type transformer, that is, transformers and supporting the protection system, , Metering system, remote control system integrated into a box, generally used for urban district power supply, field power supply field.
