Description

The application of the 250MVA/242kV three phase combined shell type transformer for hydro power station.can significantly improve the economy of the OLTC substation, and matches well with the transmission capacity of OLTC 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 the 250MVA/242kV three phase combined shell type transformer for hydro power station. In order to make the products applicable to any OLTC substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity OLTC 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 OLTC 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 OLTCtransformer 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 OLTC Transformer’s right at the first time once again filled the gap in the field of OLTC transformer research after Chinese transformer industry overcame the difficulty of integral transport of the 250MVA/242kV three phase combined shell type transformer for hydro power station, 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q: if i take a small transformer meant to be used at 120v:9v 60hz, and discharge a 360v 100uf capacitor (or similar) into the 9v winding, will i get a high voltage pulse on the 120v winding?: Yes.roughly 4.8kV .for about a millisecond at about 10 microampsThe only problem with the design is the secondary insulation on the transformer may not be of the correct insulation class to provide the shielding required. It takes quite a bit of modification to the 90degreeC insulation for a 600volt class to get that up to the 4.8kV classAlso since your going for this type of system might i recommend you avoid holding this in the palm of you hand as well.Well I knew you wouldn't do that ,i was just kidding around.you could always rob the igniter off an outdoor grille ,the capacitive discharge from them is about the same.From the E

Q: If the primary circuit of a transformer is connected to a power source and the secondary circuit has a light bulb, will the light bulb turn on and stay on when the power source is turned on? Or will it turn on for a few seconds and then turn off?This question's been bugging me because I think because transformers are usually wired through AC that the bulb would only turn on for a few seconds and then turn off, but then shouldn't current be constantly flowing so it would stay on?Thanks for and clarifications.: Umm, is the power source AC or DC? You are right, transformers usually use AC. Is it not using AC in this example? You didn't say. If it's using AC, the light bulb will stay on. The current actually switches on and off, but so fast you don't see it. Well, normally, for household 60Hz AC power. But who knows with this mystery power source. It could be 1Hz AC. If it's using DC, then it will come on for a short time (a few seconds? I don't know). Yes, current is continually flowing through the primary circuit, but after a while no current will be flowing through the secondary circuit where the light bulb is connected. It takes change in current in the primary circuit to induce a current in the secondary circuit.

Q: I am looking for a transformer with an output of 6 volts, and 1.8 amps, or any transformer that can run that cycle. Please, let me know. I've been looking for months now, and cannot find anything. Please help. Where would I buy it? Lowes?: If you don't find it you have got to make it. This is a common transformer. Probably you are finding difficulty with it's current rating.

Q: As we switch off an appliance at home, the power supply is cut off.when we switch it on , the power is on.How does the transformer regulate /manage as per our requirement: go ask Optimus Prime

Q: I have to build a transformer which are the main formulas or some source that explains this: You need to specify what the transformer is to be used for. (why do you have to build a transformer ?) (the characteristics of the core are critical to the design) Until you specify that, only the simplest of basics relating to turns ratios can be stated: 1 - Power in primary Power in secondary 2 - Voltage ratio turns ratio 3 - Current ratio 1 / (turns ratio) [from #1 #2] 4 - Impedance ratio Turns ratio squared. [ from #2 #3] **IF** it is a power transformer, I suggest getting a transformer with the same, or slightly higher POWER rating, then simply re-wind the secondary using #2 above. (I did) or Google: how to design transformer windings then pick the one that suits your needs best.

Q: What are the technical parameters of the transformer?: Transformers in the provisions of the use of the environment and operating conditions, the main technical data are generally marked on the transformer nameplate. Mainly include: rated capacity, rated voltage and its tap, rated frequency, winding connection group and rated performance data (impedance voltage, no load current, no load loss and load loss) and total weight. A, rated capacity (kVA): rated voltage. Rated current under continuous operation, can deliver capacity. B, rated voltage (kV): the transformer can withstand long hours of operation can withstand the voltage to meet the needs of the grid voltage changes, the transformer has a high voltage side tap, by adjusting the number of high voltage winding to adjust the low voltage side of the output voltage.

Q: I am an avid stop motion animator, and I have been looking for Transformers toys to buy and animate. I have one, Deluxe Class Cliffjumper, and he's really great, pretty much the same as Deluxe Class Bumblebee. He works very well for stop motion. He transforms great, he looks cool, he's got good feet, he has stiff joints, and is very flexible and poseable. But I've been looking for another Transformer toy that can do the same job. So far I've bought two, and they have not been the same quality. I bought Deluxe Classes Barricade and Bonecrusher, but Barricade was too flimsy and Bonecrusher is too top heavy with terrible feet for poseability. Anyone familiar with the Transformers toys that could give me any ideas for the better toys for animations? (Under $40, please.) Thanks!: Do you mean the monster will say rates as he kills, or do you mean the full soundtrack would be rates. So, if he have been to have a communication, all of his communication may be sampled from different video clips? If it is the later subject, then i might propose getting Jack Nicholson video clips. His voice is so creepy and he has made maximum of flicks, you have have been given to be waiting to come across something you will need. If it is the former (the place he's in basic terms quoting type video clips), i admire: Wait'll they get a load of me! Jack in Batman right this is Johnny! Jack interior the Shining you are able to not shield the fact! Jack in some reliable adult males How a pair of superb interest of chess? the pc in conflict video games hi, Clarise. Anthony Hopkins in Silence of the Lambs Hoorah! Al Pacino in fragrance of a woman Attica! Al Pacino in canine Day Afternoon

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: I broke a small transformer that I found inside of my DVD player, and I would like to have one (not for the DVD player, just separately) I would like the transformer to take in low voltage, such as a few AA or AAA batteries, and I want it to scale that up. Does anyone know where I can get one? If not are there any instructions on how to make an effective yet inexpensive one?Thanks in advance!: A transformer cannot step up or step down DC power. (All batteries are DC). That is part of their nature. A basic transformer is nothing more than two (or more) inductor coils in close proximity, often with a steel core to help with the magnetic fields. All inductor coils are basically a coil of conducting wire, most often copper.

Q: do you think transformers is cool or not and why?: In the hands of a better director, Transformers could have been great. Unfortunately, Michael Bay just made it a loud special effects extravaganza and I lost interest about half way through. Bay's movie still might have been better if it had been 30-45 minutes shorter.
