Description

The application of 400MVA/220kVmain transformer power plant 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 400MVA/220kV main transformer power plant. 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 400MVA/220kV main transformer power plant, 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: could i connect a flyback transformer directly to an ac power supply instead of a 555?: A flyback transformer is designed to work about 15 KHz with a lower primary voltage. If you connect it directly to the AC line, it will either burn up or pop a circuit breaker. Let us hope for the latter.

Q: I am using an audio transformer in a schematic, but I don't understand why. Can someone explain how a 1000 ohm to 8 ohm audio transformer works? (Radio Shack #273-1380): Audio transformers are rarely used today, as their function can be eliminated by direct coupled transistors. Transformers add distortion, and frequency problems, and should be eliminated where ever possible. I'd have to see the schematic, but I'd advise not using the transformer unless absolutely necessary. Radio shack provides zero in specifications for this, which also doesn't help. In so far as the pinout, from the photo, it appears the wires are labeled. .

Q: I was wondering what year is transformer 2 cuz the first 1 was freakin awesome!!!!!!!!! and i wanted to see a second 1 but dont know which year and i heard there was going to be another one transformers 2.: 100% yes, i believe it will be out in august 2009, but not sure. they are making it as we speak.

Q: 440 volts should be as dangerous as 11,000 volts because a transformer does not dissipates power it just converts voltage into current, my question is if the power at the secondary region is the same why it is said that it is not as dangerous.: volts give jolts amps gives cramps

Q: If you're a transformers fan, who do you think were top 10 strongest Autobots in the whole transformers universe? I mean strongest of the strongest, most brutal and powerful?lol.: BOYS: 1. James Lachlan 2. Charlie Atticus 3. Darcy Fletcher 4. Henry Oliver 5. William Avery 6. Hamish Callum 7. Angus Rafferty 8. Hugh Calloway 9. Eamon Lucas 10. Stellan Rafferty (A GP name) GIRLS: 1. Charlotte Isobel 2. Annabel Clara 3. Lucy Matilda 4. Eliza Grace 5. Laura Imogen 6. Freya Rosie 7. Madeleine Isla 8. Bronte Sienna - Ella :)

Q: I need to know how and auto transformer works and how i can get 240 with it thanks in advance and if theres a website thats explains transformers that would be great (: thnx again !!: An okorder

Q: I remember a Transformers cartoon and there was like a gas in it and if the Autobots were in a place that the gas was in there, they would turn red and turn evil and fight each other. And also Optimus Prime was dead fist and then some Autobots bring him back to life And I think Rodimus has the matrix. What was that movie called?: Yup, that was the episode in season three where Optimus Prime is brought back to life (after his death in the movie). The episode is called Return of Optimus Prime and is a two parter. The red stuff is rage and can pass if you get touched a la 28 days later. This is the episode that had Optimus return to life and get back the matrix from Rodimus (turning again back to Hot Rod). He unleashed the matrix to defeat the rage, but it empties the matrix of all it contained.

Q: What is the normal color of the transformer oil?: transformer oil are produced using the appropriate refining process, the color is shallow, generally light yellow, according to GB / T 6540 method to measure the color are below 1, and some oil color close to the water white. Oil in the use of the process, due to oxidation will produce acidic substances or sludge (sediment),

Q: Guys can you tell me that how can I calculate transformer winding?Example:- I need (12volts, 4Amps, 50Hz on Secondary's side of transformer and give 230volts 50Hz on Primary's side of transformer) how I calculate the wire's number of turns? In this case I can give different values of current like 1Amp, 2Amps, 3Amps etc on Primary's side of transformer. But I need constant 12volts, 4Amps, 50Hz on secondary. So how can I calculate.Please give an answer with an example basis on (0-12) transformer.: Basically, the ratio of voltages is the same as the ratio of turns. The currents are the inverse ratio but that kind of takes care of itself if you just deal with the voltage ratio.

Q: I need a (step-down) Transformer of the following specifications:240VAC to 24VAC 10A or 240VAC to 24VDC.(Output as 24VDC would be better/easier).I live in Victoria, Australia and need one ASAP (next 3 days or sooner)Plz tell me any store or so Also, if u wanna know the VA Rating, its 240VA.If 10A is not available then anything closest to it. say 9 or 8.5 or 8 or 6.5.Cheers!: Transformers only work with AC, so the second choice is not possible. But you can buy power supplies that have a DC output. Reference has one possibility. Search google for buy supply 24v 10a and you will find lots more. .
