Description

The application of ±800kV (HY14) of UHV converter 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: Parallel can provide the total capacity is not the sum of the capacity of the two transformers, or how to calculate? What is the principle of allocation of load load, that is, how to allocate two transformer load capacity?: The total capacity of the two transformers in parallel is not a simple addition of the capacity of the two transformers. Even if the rated capacity of the two transformers is exactly the same, the impedance of the two transformers can not be exactly the same due to the existence of design / manufacturing errors. Based on the principle of the parallel circuit, the transformer with a small impedance will share a larger current, A transformer has been overloaded and another transformer is not yet fully loaded. Can be based on the measured value of two transformer impedance (on the nameplate). Calculate the transformer with a small impedance to reach full load, the load of another transformer, the sum of the two is the total capacity of the two transformers in parallel. In fact, the transformer capacity selection is usually about 25% greater than the actual load, so the reality is usually not a full load, while the other has been a serious overload situation.

Q: What is the difference between transformer MVA and KVA?: They are megawatts and kVA Unit (power in the power of S units) Megawatts 1 MVA = 1 thousand KVA Megawatt and kVA KVA = 1000W, trillion volts = 10 of the 6th power W

Q: 315KVA transformer high-voltage side need to use the specifications of the high-voltage cable: 315KVA transformer high-voltage cable 50 square how much, but in accordance with the local power supply from the power supply program to set, not how much is their own

Q: Transformers, broken, how to repair: You can first check the insurance, if only insurance problems, you can short-term insurance; the other can buy a replacement of the same specifications, the coil can also be broken coil rewind.

Q: High power transformers are very common, for obvious reasons. Much unlike homemade transformers that I've ever built, only out of tiny enameled #26 wire, that wouldn't power anything practical.I've tried using wire as large as #6 wire to wrap a homemade transformer, as what would be needed to connect externally to 10 kVA transformers, but that simply isn't practical. The wire is simply too stiff to wrap it in tight windings.Consider the example of a 225 kVA three phase transformer, that carries about 300 Amps of current on each of its secondaries that are 277 Volts. Externally, I'd need to connect with 400 kcmil wire, that is almost an inch in total diameter. What exactly do they do in order to build transformers at this high power?Do they parallel a whole bunch of tiny windings?Do they use a cooling fluid, so that tiny wire can have a much greater ampacity?Or do they also use big wire, but the way it is constructed somehow relieves the strain resulting from wrapping it? Heat treating the metal, perhaps.: The transformers are wound using machinery that can bend the heavy wire as required. Parallel wires are used, but they are not usually tiny, but smaller that what would be needed for single wires. Transformers are wound with flat strap-like conductors rather than round wires. Liquid cooling allows the maximum current in a given size wire. PS Not everything described is used for every large transformer. Construction techniques vary. There may be other techniques and designs used also.

Q: I have been reading about pulse transformers and i am curious if there exists a pulse transformer that would take 1 pulse/second or even less and convert to very low voltage high current. If not, would it be possible to make one? Any info is very appreciated! Thx!: Pulse transformers can be wound to any turns ratio that is desired. That being said pulse transformers have small cores and therefore handle small amounts of power. You can find cores on those old mother boards that are no longer in service and junk computer power supplies also have a couple of cores. These toroids were normally used as filter inductors to remove spikes from DC or low frequency lines. You can easily rewind them for pulse transformers.

Q: As the title reads, Simply put: How did the original transformers series end? Aswell, how did some of the others, such as armada, energon, and cybertron end?: G1 never really ended it was a cliff hanger that they wanted to expand into a series called Head Masters (only aired in japan) where Armada, Energon, and Cyberton (aka the Unicron trilogy) all played into each other Armada ending with the aurobots returning to cybertron, Energon the death of Unicron, and Cybertron the closing of the black hole Unicrons death created.

Q: I am a young electrical engineer and need to review the basics of transformer saturation: conceptually as well as the mathematics and theory behind it.: Transformer Saturation

Q: even though the output voltage of a transformer can be much larger than the input voltage, the power output is nearly the same as the power input.Determine the relationship between the input and output current and the number of turns in the input and output coils.help!!!!!!!!thank you: If turns ratio is N, output turns divided by intput turns, then voltage ratio is also N, and current ratio is 1/N For example, a 120 VAC transformer with a 12 volt 10 amp secondary will have a turns ratio of 1/10, a voltage ration of 1/10 (12/120) and a current ratio of 10 (1 amp in primary, 10 amps in secondary) .

Q: I want to start watching Transformers Prime on TV, but I want all the backstory of just THAT universe, because i know there are MANY Transformer universes from Bay to Generation 1 to this. I just want to know what to read and watch before watching this series. Thanks!: I'm not sure but I think all of the latest series are connected but here are a few sites that should be able to help you
