Description

The application of the 25MVA/110kV railway balance traction transformer, 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 25MVA/110kV railway balance traction 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 25MVA/110kV railway balance traction 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: An AC generator, originally designed to provide a peak output voltage of ± 155 V at a frequency of 60 Hz, is required to provide a peak output of ± 340 V at 50 Hz. If the generator is connected to a transformer with 200 loops in its primary coil, how many loops should there be in the secondary coil in order to provide the required output?Using the formula Np/VpNs/Vs I get 439 coils, but this is too easy for a 6 mark question and doesn't include the change of frequency. I have no idea what to do and need some help :(: A transformer cannot change frequency. You can change the voltage from 155 v peak to 340 volts peak, but you cannot change the frequency. But you can change the speed of the generator and therefore change the frequency, but I don't know if that is part of the question. usually, I find that if you list the entire question with all the details, then it probably could be answered. But only part of the question will lead to incorrect answers. .

Q: Transformer Transformer Principle: Summary of words: Electrosagnetism. Magnetic electricity. Its basic principle is: a coil and the secondary coil around the same core, when a coil power, the alternating magnetic flux in the core, (magnetism) the alternating magnetic flux through the secondary Coil, according to the law of electromagnetic induction, will produce alternating electric potential in the secondary coil, (magnetic power) due to a secondary side of the coil turns, therefore, the secondary side of the voltage will not wait.

Q: I know that if I needed 600 watts at 120 volts that I would need at least 5 amps, but does the step down create a difference in amperage when using a transformer converting the 120v. to 12v?: A circular saw is an AC circuit. If you were using a DC circuit, you would be using a 1200 watt tool since all of the electricity (subtracting heat loss of course) is used to run the tool. In an AC circuit, the AC is 'alternating current', a sine wave. Only a portion of the sine wave is used for real work. The rest is used to establish and collapse magnetic fields. This term is known as 'Root Mean Square' or RMS and has to be taken into account for the problem. The value of RMS in a typical 120 volt, 60 Hz circuit is .707 or 70.7% of usable energy in the sine wave. So this leads us to the question, how many watts? Answer(120V * 10A).707 848.4W. The next one is easy, they are already watt rated so there's no conversion. 1000 Watts * 8 hrs 8KWH. 8 cents * 8 KWH 64 cents. Hope this helps.

Q: i am planing to get the eee pad transformer, can it download anything from the internet browser just like a computer does or it can only download apps from its own app store like ipad does. should i get the transformer or ipad 2 ?: i flow to attempt to make this record as clean as a danger with out growing to be use of too a lot words: reward of the iPad 2: - Intuitively simplistic (too simplistic to a pair peoples style) - Polished - eighty grams lighter (uncertain no remember if honestly anybody notices that :P) - extra helpful app shop (and stable now graphically some extra desirable ideal video games) reward of the Asus transformer: - swifter (not in many circumstances a substantial vast difference) - Flash help - - TIP: *DISABLE* flash each and each time you don't like it on the asus transformer, reason it improves velocity a lot (apple desperate for the guy that he's not allowed to prepare flash, asus/android believes the guy can take care of a few accountability) - not in straight away forward words a intake (examining/gaming) gadget, yet _can_ be used for production besides - extra helpful battery (because of the dock) - extra desirable ideal show - fairly various customization (you would be waiting to as appropriate run laptop OS's on it :D, yet it fairly is in simple terms for nerds) *My suggestion: in case you may carry your breath for some extra desirable months i ought to suggestion you to watch for the Asus Transformer 2, in any distinctive case the iPad 2 and Asus Transformer a million are fairly matched, yet i think of the Asus Transformer ought to nonetheless have the side*

Q: i am going to the mall and getting a target transformers pc game!anyone want to tell me about it?or anything i need to know or any cheats you can give me: i heard that game is really good on some consoles, but i didn't know that it was coming out for the PC too. any way, you get to pick which side you want to be on. its pretty cool, because when you are a transformer, you get to adventure around the city and blow things up! how much better could it get! um, so yeah,it's sopost to be an action packed game that you would probably really enjoy playing.hope you like it!

Q: Do stores that sells computers, printers, etc. also sell transformers: Transformers as in the action figures? You can find them at Toys R Us, Wal*Mart, or Target.

Q: i wann no wat type (kind, year, color) each transformer is, plz add the transformers name (i'd like them from BOTH the 1st and 2nd movie) plz and thank u!!!: Transformers Autobots Cars

Q: I have a standard transformer with 7 wires:2 black2 red2 yellow1 red/yellow stripedWhat connections do these wires correspond to?That is, which should connect internally to the primary coil, the secondary coil, and coil-taps (based on the number of wires, I assume that the secondary coil is tapped).I must determine this in order to connect the wires (externally) appropriately.Any help is greatly appreciated!: Transformer Wire Colors

Q: can any one give me a fast time line of transformers history: The gods Primus and Unicron nearly destroy the universe fighting until Primus tricks Unicron by imprisoning them both in metal planetoids. Unicron becomes giant transforming world devourer and Primus becomes Cybertron, bringing to life the transformer race that will fight Unicron in his stead. The robots of Cybertron eventually begin civil war which go on for millions of years, the evil Decepticons vs the heroic Autobots. Unicron finds Cybertron, the Autobot leader destroys him with the Matrix, the transformers fulfill their destiny. Their war continues until Cybertron is nearly depleted so the planet is reformatted and the race adopt Maximal and Predacon castes. New wars begin until balance is struck and Cybertron becomes technorganic paradise

Q: What is the role of the pebbles in the transformer base: Transformers base need a pool around the pool inside the pebbles, the role of the pool called the reservoir, that is, when there are accidents, transformer oil leakage, the pool can store oil to prevent the oil flow everywhere, the pool filled with pebbles, in order to Safe, on the one hand is to prevent oil burning. As well as for the convenience of the transformer body above, the following is better than a deep pit convenient? Transformer oil pit volume is calculated in accordance with the transformer oil, there is a certain depth.
