Description

The application of the 400MVA/230kV power 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 400MVA/230kV power 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 the 400MVA/230kV power 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: I think it will. Michael Bay who doing the movie has a history of messing up classics. Godzilla is my prime example. So, what do you think? Transformers the movie: Good or Bad?: Well, unfortunately you have some facts wrong, so chances are you may not like the movie you are going to see, because you are not sure what movie you are talking about. Godzilla was directed by Roland Emmerich of Independence Day fame. Michael Bay did not direct that movie. MIchael Bay has been associated with much better movies such as Armageddon, The Rock, Bad Boys and Pearl Harbor. Okay, maybe Pearl Harbor wasnt that good, but the rest of them are a hell of a lot better than Godzilla. About Transformers, no, it will not suck. See, there is someone else involved in the movie who wont let it suck. Steven Spielberg. With those two involved, and yes I realize that Spielberg is only Executive Producer but he is still very involved, this movie is going to be great.

Q: SGB10 transformer and SC (B) 10 transformer What is the difference between the two series where the difference, specifically to the 10 type and where the hope that the knowledge of a detailed explanation Thank you: The first is a three-phase isolation low-pressure foil around the second is a three-phase dry low-pressure foil around the 10 type is the same as the performance code level is the loss level is almost. The first of the matrix is dry or oil immersion is necessary to see the kind.

Q: I have a friend who lives in a place that she converted to a liveable space at a movie studio complex; however, the space is right above the transformer used by the studios for power. At night we can sometimes hear some buzzing sounds. How dangerous is this? We've heard things like it causes cancer in the long run, and that it is simply not safe. Does she have to worry about it? She's been there about two years.: Transformers can produce powerful electromagnetic fields, but there is no definitive answer on the safety of living next to transformers. Some people believe the electromagnetic fields cause health problems, and others do not. Bona fide research on health risks has produced sometimes contradictory results. One thing is for sure, high capacity transformers occasionally explode if they get overloaded, but these types of transformers are not allowed inside of buildings.

Q: b)Describe an important industrial application of one of the above devices (apart from transformers)C)Explain how this device works-that is ,what the electricity actually does: A transformer is a device that allows you to easily and efficiently convert an AC voltage to a different voltage. When you do this, the current is converted in the opposite ratio. For example, if you have a 100 volt 1 amp source and you convert it to a 1000 volt source, it will have capability of 0.1 amp. It is made by winding wires on iron cores. See the reference for details. It is very important for the transmission of AC power, as it can be changed to a very high voltage for efficient distance transmission, and back to low voltage for use in homes. .

Q: does anyone know how big the transformers are in the movie or have an online reference?: lol to tell you the truth, I've been to the L.A. Transformer's movie premiere, I've seen a life-size BumbleBee model with my own eyes and it's about 2 stories tall (I also took some pictures but not clear though)? Optimus Prime, about 3~4stories tall? And if you use search engines, you might find some funny insider stuffs from fansites, have fun!

Q: I just finish watching Transformers Revenge of the Fallen for the third time. IT was awesome I 'm getting it on DVD and hoping for it to come out as another transformers.: It looks like it's set for July 1st, 2011.

Q: come on.the battle scenes and all the transformers were totally awesomebut.all the small jokes that sam and his parents and other various characters madejust killed itlike they were actually trying to add a comic element to it.and what is with the transformers cussing? it doesnt feel righttransformers dont cuss.lol: I concur. Transformers 2 had some really awesome cinematography, most notably the battle sequences, but it really wasn't worth the praise. The jokes felt too forced, the film felt rushed, and the acting was terrible. It wasn't awful like critics are saying, but I wouldn't really watch it again. The first Transformers was better because the jokes didn't feel too forced and the film didn't feel really corny like its follow-up.

Q: Transformer is the transmission of electrical equipment: Transformer is the power of the transmission of electrical equipment, it is the primary energy transformer through the electromagnetic coupling, to the secondary side, we need to become the voltage and current, the frequency does not change the power supply.

Q: chemical transformer.: to transform WHAT into WHAT?

Q: A 630 kVA, 11kV/400V transformer. Rp, Xp, Rs, Xs, Rc, and Xm are given. How to find secondary and primary? Do I need to calculate the total impedance referred to the primary and secondary or can I calculate currents without it?: Given its capacity this is almost bound to be a three phase transformer. You need to know the connection of the primary and secondary windings (Y or Δ) to determine the windings' currents. You can basically calculate the rated currents from the kVA rating and voltage without using the impedances, eg. Ip primary rated current 630/(11 x 3 x √3) which assumes a 3 phase transformer with a Y-connected primary. Edit: If the capacity value is totally unreliable then there's no way you can find the rated current with only the other values you give. You need the load impedance as well.! This applies whether it's a single or a three phase unit I'm afraid. Why do you bother me with useless data? If you do this kind of thing to your employer in later life you'll rightfully get scalded!! On top of that you don't even initially say please or later apologise for such a gaffe.
