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 am doing a school project of a Wind Turbine; and I need to show a transformer or what a transformer is in a wind turbine. I have just 1 question. WHY DO PEOPLE USE TRANSFORMERS?: Kiran okorder

Q: i heard a new was coming out ,i hope so ,the first two rocked!!!: Transformers 3 is estimated for a July 1, 2011 release.

Q: A transformer is a two coil component that uses electromagnetic induction to pass an AC signal from its input to its output.?How and why are transformers used on electric wires? What would be their purpose??Why do we hear that these transformers break at times?: Transformers are mainly used to step up or down of a voltage. For example, generators output are normally in the magnitude of 100 volts per phase or so for a 3 phase system. When the output is to be delivered to the users, sometimes, it could mean 100's of miles away. We all know loss will naturally occurs during the travel of the power. So it would be necessary to jack the voltage up to thousands of volt at the source and then at the substations local to the users return to the normal main voltage, such as 240 volt in UK and 110 voltages in USA. The process is done by transformers and can only be done by AC (not DC) system by making use of the turns ratio of the Input/Output of the transformers. Transformers carry power and sometimes the insulations between wires in the coils breakdown which in turn causes transformers to breakdown.

Q: describe a stabilised transformer: I'm only guessing that you may be reffering to a transformer that is equipped with taps on the windings that allow for +/- 10% votage changes on the secondary to maintain a fixed voltage when the input voltage (primary) varies or the load on the secondary varies. Thus stabilizing the voltage to the load. These are called TCUL (tap changeing under load) or LTC (load tap changing)-the more common term-transformers.

Q: how are opyimy and megatron ( or w/e the f their names are)bros and hoes if they cant have roboet sex!!! if so wheres their mother and is the creator sexist about girls there is no girl robots and for that matter has some1 made a transformers porn yet.: I'm going to answer your question with a question: Did your parents drop you on your head when you were a kid?

Q: How to tune to 14V? Why I tune the value of the above voltage meter has been always beating.: The above two parameters can also be extended or reduced by the ratio. Other parameters can be considered, as shown below.

Q: I have an old xray machine with a large step down transformer.Its not shorted but the paper insulation looks to dry. Is there a special oil for this? Thanks.: there is no oil for transformers. they are kept dry by all the heat they generate. it cooks the moisture out. if there is a specific reason you are worried, please do tell. is it going to be stored or go unused for a while? is there a lot of moisture in the area of operation? if not, i would not worry about it. it sounds as if it might be near the end of its life cycle as is. on the bright side transformers dont just burn out. there must be a reason for the failure. moisture is not too bad, but water is.

Q: I will vote for the best answer based on the use of simple vocabulary, I don't know much about transformers so try to keep it as understandable as possible. I know it's not a simple subject, thanks!: As you may know, transformers only work with varying current: AC, of whatever frequency. The varying magnetic field produced by one coil will induce a proportional current in the other coil. That's how they work. But the varying magnetic field will also induce currents in the metal core of the transformer. These are called eddy currents, are a waste of energy, and will result in excess heat. By using thin laminations for the core, and insulating the laminations from each other, transformer designers can minimize these eddy currents, and keep the transformer efficient. Don't forget my best answer.

Q: i have a flyback transformer that i want to make a tesla coil out of and i need a diagram for the wiring configuration.: The modern flyback transformer is also used to generate the DC operating voltage for the TV set. You have a lot more wires than you need to use. You need to get a copy of the wiring from someplace like a Sears repair shop and hope you don't have a built-in high speed diode and filter cap in the same package. The last thing you need is to try to run your Tesla coil from a DC source on the primary. I believe Ramsey electronics makes a package Tesla kit that runs off a flyback. Your coil will not produce a very large brush discharge but it should be a good demonstrater which will have a safe, low current spark.

Q: Is the transformer a power adapter?: It depends on the transformer voltage, current, power and other data can be suitable for your job requirements of a machine. Such as computers
