Description

The application of the 150MVA/345kV three phases self coupling generator interconnection transformer.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 150MVA/345kV three phases self coupling generator interconnection transformer. 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 150MVA/345kV three phases self coupling generator interconnection 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q: Hello everyoneI have a 110V hardware plugged in at home (we use 220V) by way of a step down transformer and I was wondering if transformers 'use' more power than usual. I don't want a nasty electircal bill.Because even when the hardware is 'off', the transformer itself is still on. It still hums. I am wondering if the transformer is constantly pulling power out of the wall socket 24/7 if I leave it on.Any help will be greatly appreciated. Thanks all.: Mike, here is an easy approximation with no tech talk you can perform. Leave the power on to the transformer but remove the load and let temp stabilize. Feel how hot or better yet put a thermometer on the transformer. This heat is a direct result of transformer losses while idle. Next remove power to the transformer and devise a metal box to put a lamp in to heat the transformer overnight. Try to capture all of the lamp heat into the transformer to heat the core. Try this using various lamp wattages. When the temperature rise from the lamp equals the temperature rise from running the transformer idle the lamp wattage will be a close estimate of the power wasted by the transformer at idle. A wattmeter will also tell you this but they can be expensive. A good meter and an oscilloscope will be necessary otherwise but that is another story. Heat is always wasted energy the more produced the more it costs you to run. Regarding if you should let it run the answer is sure why not. You probably already have transformers running in your house all of the time. Door bell, Furnace, hot water tank, may be a few.

Q: I want you guys to tell me if the movie transformers its a good movie or not? Why?Thanks, See Ya!: If you watched it as a kid, it was a great movie, it had all the elements from the cartoon, and stayed true to almost everything(they had to change Megatron, he turned into a gun) And if you never saw it before it is still a great movie, great story, great acting(with a hot Megan Fox) and tons of great action. The effects really make the scenes when they transform believable.

Q: how do i work out the voltage output of the second winding on a transformer if i know the Primary voltage is 35v and the first winding has 355 windings and the second winding has 4500 how do you do this ?thanks: Assuming that the transformer is designed for a primary voltage of 35 or more, then you can simply multiply the applied primary voltage (up to the design limit) by the turns ratio and this will give you the output voltage. In this case: output voltage 35 x 4500/355 444.

Q: What is the principle of the conversion of the transformer? How to restore the secondary side to the primary side?: 1. The principle of the return is the balance of the magnetic potential before and after the countdown. The various energy relations should remain unchanged. 2. Potential and voltage of the count: the transformer once the number of turns W1, the number of turns on the secondary side W2, W1 / W2 = k ??? There is a return after: E2 '= k * E2 ????????????????????????????? U2 '= k * U2

Q: I went to go see transformers yesterday and one of the previews shows a bunch of people at a party with someone videotaping the party. Then there are explosions in the distance and at the end the head of the statue of liberty lands in the street. They don't say what the name of the movie is but it has a january of 2008 release date. Does anyone know the name of this movie?: I thought I saw, in quotes, that it was called Bad Robot. Maybe it is/was a working title.

Q: I know there has been plenty of Transformers anime over the years, but is there any Transformers manga?: Have you tried googling it? Good luck! I remember seeing Transformers in JPN since I was little I think they've been around since the 80s. At least I've seen the toys in JPN since then.

Q: A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil.A How many turns of wire does the secondary coil have?B When the transformer is running at full power, what is the current in the secondary coil?C The current in the primary coil?I know what equations I would use, but I don't have enough information to use them. Can someone at least set these up and show me how to plug the numbers I have into the correct equations?: A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil. Power output Power input Power Volts * Amps 350 13,000 * amps Amps 0.0269 amps current in the primary coil? House voltage 120 volts 350 120 * amps Amps ≈ 2.92 current in the secondary coil? Amp Ratio 2.92 ÷ 0.0292 100 : 1 Wire ratio 100 : 1 A How many turns of wire does the secondary coil have? 50,000

Q: how to calculate the secondary current of the transformer for example 1200 amps in primary ,primary voltage is 220kv and the secondary voltage is 34.5 kv of the transformer .: For an ideal transformer, the voltage ratio is set by the turns ratio, so the transformer is a stepdown with the ratio of 220/34.5. The current ratio is also set by the turns ratio, but current goes up as voltage goes down, so the secondary voltage is 1200 x (220/34.5). Again, for an ideal transformer only.

Q: i need a transformers costume that can transform into a car, truck, etc i need to buy it for this kid for his birthday. medium size please. and he wants it as optimus prime.he wants it to look good and if he doesn't like it, well hes gonna be sad: wrap urself in tin-foil. lol

Q: I would like to get my grandchild all the transformer movie dvds but don't know the names of all of them. please help and thanks: Wow that's the best gift you could give ! I would be thrilled to get that ( and I'm a teenager, LOL ). Someone already took my answer. :( But yeah I'll repeat it anyways: Transformers, Transformers: Revenge of the Fallen, and Transformers: Dark of the Moon ( BTW I heard it comes out November 15th, not September 30th, I'd get that checked out ). What a lucky grandchild, I'm buying them all on blue-ray when the third one comes out : If he has a game station (xbox 360 or ps3) why not get him the games? :p too much? okay nvm.hope I helped
