Description

The application of 1140MVA/500kV Three-phase integrated 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 1140MVA/500kV Three-phase integrated 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 1140MVA/500kV Three-phase integrated 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 really want a better transformers than 4 1 was great 2 was crap 3 good 4 worst of them all: Yes, there will be a Transformers 5. When we don't know. Many people are thinking 2016 or 2017, but i have a friend that works in the movie theater and she knows the next movies for the next 2 years and Transformers 5 was not on the list. Is that because Transformers 5 has no name yet? Maybe. So Im assuming its coming out in 2017 or 2018. As for Paramount pictures they are not even thinking about Transformers 5 yet. As they stated once its one movie at a time.

Q: A transformer is used to step down a voltage of 11KV to 220V. Given that the transformer has 3200 turns in the primary, calculate the number of turns in the secondary coil.Another transformer is used to further to step down 220V to 110V. its input current is 3A and the output current is 5.6A. Calculate its efficiency: you have fifteen watts moving into, and in basic terms 5 going out, so the customary gadget performance is merely 33%. yet dissimilar the loss arises from themes different than the transformer; specifically, the rectifier gadget will chew up approximately 10% all by ability of itself.

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 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: Is the transformer a power supply?: Narrow power supply: refers to the other forms of energy can be converted into electrical energy devices, such as: generators, a variety of batteries; where the transformer does not belong to the power supply. Generalized power supply: refers to the ability to output electrical devices. It includes generators, various batteries; transformers; regulators; etc.; where transformers are power supplies.

Q: Hello,Recently, my air conditioner broke and I hired a man to come fix the machine. Unfortunately, he did not help my situation and possibly made it worst.Initially, he informed me that my transformer was broken and so said that it needed replacement. However, when he replaced the transformer, both the transformer and the circuit board blew out. Now, he's making me pay, not only pay for his services, but also for the two additional parts. My question is: Is is possible that the circuit board caused this issue? Or did he mess up on the wiring and blow both parts out, by mistake?I just need to know, so I don't pay for something, originally not of my cause.Thank-you.: Transformers don't normally fail for no reason. In most cases, something caused the transformer to fail, so it is incumbent upon the person servicing the unit to figure that out first before installing another transformer and powering it up. If it can't be determined what caused the failure, it is best to install an in-line fuse so, if there is an issue, the fuse will blow before taking out the transformer and the circuit board. Having said that, in a lot of cases, the circuit board has its own built-in fuse to protect the board from cases such as yours, so the board fuse should have blown before the board became damaged. I don't have much confidence in what your man did, so I'm more likely to blame him for blowing out your circuit board and the new transformer, unless he can prove otherwise.

Q: I need to find out.I am a huge Transformers fan.: I have seen both Transformers movies as they are both real good movies you should see both of them

Q: I check the voltage between x1 and x2 I got 120v but between x1 and ground on primary I got 40v and between x2 and ground on Primary I have 50v, if I connect x2 to ground won't it short the transformer? Thank you: NO IT WILL NOT SHORT THE XFORMERCONNECT X2 TO GROUND. PREFERABLE AN EARTH GROUND, BUT AT LEAST THE ELECTRICAL GROUND.

Q: i think transformers, iron man is like just a man made siut transformers are the real deal.: transformers fer shure! x

Q: I need a specific transformer to make 5V go up to 170V. It can be a little high and I can just use a potentiometer to lower it if needed. Where can I find such a specific transformer?: Since okorder
