Description

The application of the 430MVA/242kV main 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 430MVA/242kV main transformer OLTC auto-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 430MVA/242kV main 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:Hi, I need a High Frequency( example~200khz) High voltage(200 000v) power supply at low microcurrent, I know that a Tesla coil fits the bill very easily . But I need to manually VARY the frequency(say from 100khz to 200khz ) while keeping the High voltage the same? Is this possible, Can some one guide me where I can buy or build this? Can I just for instance connect just a van de graaf or a rectified Tesla Coil to a function generator? If not what do I need to do to achieve what I want? I have been searching without help so your support is much appreciatedThanks: The Tesla coil needs to operate at the same resonant frequency on both the primary and secondary sides of the loosely coupled transformer. The resonant frequency is set by the inductance and capacitance of each side. The problem is there are no high voltage solid state capacitors (varactor diodes like you see in r.f. receivers that adjust the tank circuit frequency) on the primary side, and no way to adjust the top hat toroid capacitor on the secondary side (unless maybe it was a mylar covered balloon with vacuum deposited aluminum that could be remotely inflated or deflated). So you are stuck with whatever high voltage capacitor and toroid top hat you have on hand, and the inductance of the coils you wind that ends up being the resonant frequency. Even then it takes a lot of fiddling to get both in tune to give the maximum voltage output. The input frequency to the primary coil (the 555 circuit used in the step up with the flyback transformer- its frequency was chosen solely due to the flyback's frequency design) has little to do with the primary's resonant frequency; again that is set by the capacitor used and the size and number of turns of the primary coil.

Q:i just bought transformers Infiltration and Stormbringer graphic novels of idwi know that they are continuing and continue like this1.Infiltration.2.Stormbringer.3.Escalation.4.Devastation.5.Revelation.i wanna know what graphic novels come after these and what is the name of all of these mini series together?: Megatron Origin is the first story, then Infiltration, Stormbringer, Transformers/New Avengers, Escalation, Devastation, followed by Maximum Dinobots. The Spotlight (Revelation) stories interweave into the main plot as well (4 volumes all together). All Hail Megatron is next, with more Spotlight stories collected in All Hail Megatron vol. 3 4. Then Last Stand of the Wreckers, Transformers Bumblebee, Transformers Ironhide, and Transformers Drift. The ongoing monthly title follows, as of this typing only two paperbacks collecting it are out. Here's the chronological reading order when you get your hands on every paperback: Megatron Origin Spotlight: Blurr Spotlight: Shockwave Spotlight: Cliffjumper Spotlight: Wheelie Spotlight: Hot Rod Spotlight: Sixshot Spotlight: Ultra Magnus Spotlight: Soundwave Infiltration ch.0-3 Stormbringer ch.1-3 Infiltration ch.4-5 Stormbringer ch.4 Spotlight: Kup New Avengers/Transformers Escalation ch.1-2 Spotlight: Ramjet Escalation ch.3-6 Spotlight: Galvatron Spotlight: Optimus Prime Devastation ch.1-4 Spotlight: Blaster Spotlight: Arcee Devastation ch.5-6 Spotlight: Mirage Spotlight: Grimlock Spotlight: Cyclonus Spotlight: Hardhead Spotlight: Doubledealer Spotlight: Sideswipe Maximum Dinobots Spotlight: Drift All Hail Megatron ch.15 Spotlight: Metroplex Spotlight: Jazz All Hail Megatron ch.1-14 16 Spotlight: Prowl Last Stand of the Wreckers ch.1 Transformers ch.1 Last Stand of the Wreckers ch.2-3 Transformers ch.2 Last Stand of the Wreckers ch.4 Transformers ch.3-4 Transformers Bumblebee Transformers ch.5-6 Last Stand of the Wreckers ch.5 Transformers Ironhide Transformers Drift Heart of Darkness The rest following aren't in paperback form yet

Q:how many primes are there in transformers?: G1 (comic cartoon) Prima - first Transformer w/Matrix The Fallen (formerly Megatronus Prime) Primon - unofficial Matrix holder Prime Nova Sentinel Prime Optimus Prime Rodimus Prime Beast Wars (not Primes per se, but variants of) Optimus Primal Lio Primal Big Convoy Robots in Disguise Alpha Trion Optimus Prime Unicron Trilogy Vector Prime Optimus Prime Animated Ultra Magnus (formerly Ultra Prime) Longarm Prime Sentinel Prime Optimus Prime War For Cybertron/Transformers Prime Zeta Prime Optimus Prime Movie Dynasty of Primes (names unknown) The Fallen (formerly Megatronus Prime) Sentinel Prime Optimus Prime IDW Nova Prime Zeta Prime/Sentinel Prime Optimus Prime Edit: technically there are more but to mention them all would be a mess, Prime in Transformers typically means Matrix holding Autobot Leader, or original child of their god Primus, and I only bothered to mention them. Omega Prime is a temporary transformation, not a full-on character, and Nemesis Prime was once Optimus Prime from another reality which is why I didn't list him. Shattered Glass and Primal Prime are fan creations. Generation 2 Optimus btw is the Same character from G1. I know what I'm doing (It was only fair to mention the Beast War Primals because they were Maximal leaders, not Prime elects)

Q:I know my user name indicates that I looooove X-Men but I loooove Transformers too. I was wondering if anyone knew who the transformer that comes out of the pool is. I have looked at the concept art and can't figure it out.: Looks like Megatron to me, but this movie is going to suck ***. It has shia lebouef in it and he is such a crappy actor.

Q:how to ground transformers at substations??: The steel body of the transformer and the neutral (wye point) should be bonded to a suitably installed and tested rod or mat by a cable capable of carrying the fault current that could occur. The wye point, in some cases, may be connected through a fault limiting resistor but this involves extra protection equipment and proper coordination. The actual type of ground depends on local conditions. A simple rod may be used in conditions where the ground has low resistance, a mat or multiple rods may be used in others. The resistance of the ground should be tested to meet local codes (usually 5 or 10 Ω). Since the design involves engineering and knowledge of national and local codes, it is best to have this done by a reputable engineering company.

Q:A 2300/230 V step down transformer is rated at 70 kVA and 60 Hz. Its windings have the following resistances and inductances : Rp 0.093 ohms, Xp0.280 ohms, Rs 0.00093 ohms and Xs 0.00280 ohms. The transformer's rated current at the secondary is 3261 A. Assume that a10 from 2300/230 V and calculate the no load voltage for unity 0.7 lagging and 0.7 leading power factor.: this is quite a typical question. there will be many examples similar to it

Q:I have been telling everyone that I would never get the IPad because it doesn't do anything. A tablet is a great idea, but the IPad has way better potential. The IPad is currently useless. You could have music, movies, web on the go, books and games with an ITunes App store. Those are pretty much the highlights.The Asus Eee Pad Transformer on the other hand is a tablet that has music, movies, web only with wi-fi, books games, Android App market, and what i'm really looking for in a tablet, the ability to view and modify microsoft office documents (word, excell, power point). The advantage that the Transformer has is a detatchable keyboard, so it can be used as a type of netbook or tablet. The plus about the keyboard dock is that when your tablet needs charging and you connect it to the dock, it will recharge your tablet. Total battery life of the tablet plus dock is 16 hours(8 hrs/e).So now, is ther anything out there similar to this Eee Pad Transformer worth considering? Should I get it or not?: ASUS Eee Pad Transformer Tablet is very responsive and has lots of apps that provide me with convenience and entertainment. The keyboard layout is better when you rotate it upright than when it is in landscape mode. There is a nice bezel area to hold the tablet without getting your fingers onto the screen. Says on the website you can sync it with your home computer, but I haven't done that yet. I think I might buy the keyboard dock because typing on a touchscreen is very slow. PROS: Fully customizable Tons of apps(honeycomb apps are growing) Great price Gorilla Glass Cons: Short charger cable no usb port besides the one that is for charging and connecting to computer

Q:hi guys can any of you give me advice on wot i need 2do on removing and replacing a faulty line output transformer on a rear veiw projection tv as i have the part and the local tv shop wont fix it 4 me.wot would be the best way to discharge the power from it first and could i jus cut the 2 wires on the old 1 and use connector blocks to connect the new 1 in would this be ok to do or do it need to soilder connected on?. and is there any adjustments that would need to be done to the set when i have it installed be4 i turn it on any help much appreicated: Solder the joints!!!!It is OK to use the old connectors!!!! Be sure that the power of the new transformer it is the same with the power of the old one.

Q:Transformer total circuit breaker rated current 380v, rated current 1000a, the rated capacity and output power how to calculate, I did not learn more points: Kva is apparent power, KW is active power. inspecting power: S = 1.732UI = 1.732 × 0.38 × 100 ≈ 65.8 (Kva) Active power: P = 1.732UI cosφ = 1.732 × 0.38 × 100 × cosφ
