Description

The application of the 31.5MVA/220kV single phase 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 31.5MVA/220kV single phase 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 31.5MVA/220kV single phase 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:I have a transformer with serial number T.K.K EHT 66001 S-2. I confused with input (primary) wires. it has 5 wires (white red brown yellow and blue). which wires is used for 220 vac?? please help.: It looks like you MAY have an auto-transformer, ie only one winding. Off hand, I would say the white is supply live and blue the common return. If you measure the DC resistance of White to all the others and record reading. Then red to all others as above and same with brown, yellow and blue. The pair with highest reading Should be the primary, it doesn't really matter which is live or neutral, as long as you take the return of the secondary to the neutral. The other 3 wires will give you 3 different voltages with respect to neutral, however the EHT in the serial No. May indicate Extra High Voltage, which is not 220v. by any stretch of the imagination. Is there no information whatsoever on the transformer itself? Clear as MUD I know, but I'm not good at explaining things. Your meter should be at the lowest range, as this is DC resistance you are measuring, not AC.

Q:I got an Alien bees unit and in order to convert the power from 120v to 220v I have to get a true magnetic transformers according to their website, what does that mean?: All transformers are magnetic. Perhaps if you would provide a link to the product in question, maybe even to its user's manual, some more information could be gleaned that would allow a more helpful answer. I have no idea what an alien bees unit is. -------- Ok with that I was able to google some more info. So you have a unit that came with a 120V power cord, intended to be plugged into a north american AC power outlet (120V, 60 Hz), and you need it to run on your local current, which is 220. You don't have a power brick or wall wart, the AC goes right to the flash unit. Yes? And the specs say it draws up to 6 amps at 120 volts, 60 Hz. What they're talking about is that you need a true voltage conversion transformer (usually this is actually an autotransformer), NOT any other sort of voltage converter. Travel stores in this country (US) sell these small and cheap voltage converters, made to allow use of certain high wattage devices (up to 1500 watts) on 240 even though they're made to run on 120. But they don't use a transformer, they use a capacitor and a diode. They're ok for things like curling irons and space heaters. They're completely unsuitable for anything electronic. You can usually tell the difference between a true transformer voltage converter and the voltage converter by weight. The latter weigh just about nothing. Whereas even a 50 watt transformer will sit fairly heavily in your hand. For a device that pulls 6 amps at 120 volts, you need a transformer of at least 1000 watts capacity. I've linked one below. Of course that is a US seller, but this will give you an idea of what to look for. Note that it weighs 17 pounds (about 8 kg) and is about 5 x 7 x 8 inches (13 x 18 x 20 cm). There just isn't any way these get much smaller or lighter. .

Q:If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts?: There is actually a phasing to the transformer windings. If you connect them in series with the phases adding (both hit + 12 at the same instant) you get 24 volts out. If you connect with the phasing wrong (one hits +12 while the other hits -12) and put them in series the output will be zero volts (and they might overheat). If you connect them in parallel with the right phasing you will get 12 volts and the amperage will add to give you the sum of their amperage. If you connect in parallel with the phasing wrong you will get zero output voltage (and the danger of overheating). If the transformers do not make their phasing clear put a voltmeter on the output and briefly turn on the primary while seeing if you get zero or the voltage you want. If the phasing is wring swap the wires of one transformer around and check with the meter again.

Q:I need to find a transformer that will convert 480 input to 240 output for a motor controller. Where can I get this type of transformer? I've only been able to find 120/240 transformers.Thanks.: Out okorder

Q:I have some questions about some of the transformer toys1)Why is it that the stores never put out some of the action figures I'm looking for like Ironhide and Starscream2) Why am I seeing a bunch of voyager class Ratchets and deluxe class autobot wheelie on shelves in every store i go to that sells transformers stuff3) Why do stores put on there shelves either a bunch of leader class optimus primes, or a bunch of leader class megatron and there's barely any jetfires 4)where do you think is the best place to buy transformer figures, toy R us, walmart, target, ETC, but don't say internet5) this last one is just your opinion and its what do u think is the worst figure you have or is in your collection and tell me why, for me its voyager class the fallen, because getting him was really hard and he's not even worth being that rare.So those are my questions, i hope you can answer them all and thanks: Sorry Koda you're incorrect! they do no longer remodel into robotic, regrettably. the only one that combine and have a robotic and alt mode are the legend figures as for now and overload will join the mixture interior the legend mixture. desire it enables. P.S.- the image of the hyperlink is the ideally suited classification that fee $a hundred

Q:During the trailers before the movie transformers, there was a trailer for a movie that looked like it was done by an amateur video.It didnt have a name but it had the statue of liberty flying through the streets.Anybody know the movie or wat the movie is about?: Search okorder

Q:I want to step down a 240Vpeak signal to 24. Anyone know where I can get a transformer to do this? Also does frequency have a dependence on a transformer? The signal I am looking at has around 55Khz frequency. Thanks for your help: You won't be able to find a transformer for that frequency, unless you are lucky. You will have to wind your own. Probably a ferrite core is best, depending on your power level, which you did not mention, and is an important design factor. If this is a very low power signal (you do use the word signal), perhaps a capacitive or resistive voltage divider will be enough. Or search for an audio signal transformer. .

Q:I think they can, especially since there has been a series of some sort in the US and/or Japan series on going since 1996. Here is the track record:The Transformers (1984-1987 season 1-4 in the US)Japan's cotinuation of G1:Transformers: Headmasters (1987)Masterforce (1988)Victory (1989)Zone (1990)Beast Wars: Transformers (1996-1998)Japan's continuation of Beast Wars:Beast Wars Second (1998)Beats Wars Neo (1999)Beast Machines (1999-2000)Transformers: Robots In Disguise (2001)Armada (2002-2003)Energon (2004-2005)Cybertron (2005-2006)Animated (2007-present)This also includes two movies with a third on the way:Transformers: The Movie (1986)Transformers (2007)Transformers: Revenge Of The Fallen (2009)They might not as long running and continuous as the Simpson but to me the franchise has a good case for being one of longest running series with all of its incarnations.: Not to downplay Transformers or their cultural impact on the world- but I'm going to disagree. Certainly Transformers is a world renown series, and has stayed active for an exceptionaly long time in a variety of different itterations- but I wouldn't QUITE go so far as to say it is one of the longest running although it is certainly more than most). I am assuming we are just talking about animated series too (since well, this is the animated section) because in the broad scope of ALL TV, then Transformers can't even light a candle to stuff like the Today Show or Sports Center which have both been going on for decades and have tens of thousands of episodes. But even if we are just looking at animated features, I would point to Sazae-san. That same series has been running since the 1960s and has thousands of episodes- and is still ongoing If we are looking at number of variations and types of shows, I'd say Mickey Mouse. He has countless movies and short films, and more than a few lengthy series that have been showing up for decades and decades still to come. And even if we are talking about animated series about robots- Gundam still has Transformers beat. It's been going on since ths 70s and has around twelve 25+ episode series, with dozens of specials and movies, and more than a handful of OAVs that range from a few episode on up to 13 or more. (absurd Gundam graph: anidb /perl-bin/animedb.pl?sho ) So yes, Transformers is quite exceptional- but there are just too many giants out there for me to consider it to be one of the longest.

Q:I have a 120v X 24v step down transformer that is capable of supplying 30 amperes. I need to convert the output to dc to supply a project I am working on. I have a bridge rectifier capable of handling 10 amps continuously, but nothing that could handle the 30 amp output. What would occur if I put the rectifier on the input side (with no filter capacitors) and fed the xfmr the DC voltage with 120hz ripple? I suspect the xfmr wont like the 120hz input and generate excessive heat. Anybody know for sure? The xfmr has a laminated iron core and copper windings.: The transformer will not work correctly with pulsating DC. It will overheat.
