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:A transformer has a 100-turn primary coil and 1000-turn secondary coil. The primary is connected to a 120-V AC source and the secondary os connected to an electrical devic with a resistance of 1000 ohms.what will the voltage output of the secondary be?what current flows in the secondary circuit?what is the power in the seconday coil?what is the power in the primary coil ?what is the current drawn by the primary coil?: The ratio of teh secondary to primary turns gives you the voltage multiplication on the secondary. Thus N 1000/100 10 So the secondary voltage is Vs Vp*N 120V *10 1200V The secondary current Is Vs/Rs 1200V/1000 Ohms 1.2 A Power in secondary Ps Vs*Is 1440 W Power in Primary has to be the same as secondary (or less due to losses) 1440 W Ip Pp/Vp 1440/120 12 Amps

Q:I enjoyed both of these titles' first games very much. I am a big Transformers fan but I also love the first person shooting action Borderlands has to offer. I only have enough money to pre-order one and get it on its release date but I can't decide. What are your opinions? What will I get better gameplay value out of? Which do you think has a better pre-order bonus? I welcome any and all opinions and answers!: If you are a fan of Transformers, get Fall of Cybertron because you'll be able to play as Grimlock (Dinobot) or as the Constructicons.

Q:Can transformer be used to change direct current e.m.f? If not , why?: The normal one with coils can't do DC, but in college we build one that used magneto-hydrodynamic energy that did DC to DC. A closed circuit pipe filled with mercury. A large magnet on one side, an electric current passed through the mercury. The mercury is thus pumped around the circuit. At another magnet, electrodes take current out of the moving conductor (the mercury). Its DC to DC. Only useful in a college lab to prove a point, but the physics works.

Q:I want to get the asus transformer, and on the web, there is stuff like asus transformer prime, and i want to know the differences between both and the negatives and positives of each. Asus transformer prime is $100 more than the asus transformer, so I want to know if it's worth it or not. Thanks!: Yes the transformer is different and older than the transformer prime. It has NVIDIA Tegra 2 processor vs the tegra 3 in the prime. Tegra 3 is a quad core 1.3 ghz processor and the tegra 2 is a 1ghz dual core. You should definitely get the prime but dont buy it yet. ASUS sold out the first batch which had a few issues, and they are releasing the bugs fixed second batch soon with Android 4.0 Ice Cream Sandwich pre installed (I could be wrong here), so wait till then and buy it with the keyboard dock which doubles the battery! I'm waiting for the prime to come out soon too! It is very thin and thinner than the galaxy if not the same. Hope this helped.

Q:Transformer voltage ratio and current ratio.: High voltage side voltage / low voltage = low voltage current / high side current = variable ratio

Q:I'm a beginner in electronics ,I have a big , old transformer (I think it is AC) , only supplies + current. (36 Volts)I also need - current to drive an amplifier.So i think it's an AC to DC converter i need. (It's just a guess , i don't really know.)How can i achieve this ?Note : If you need additional details , please include how i can get that detail , just in case i don't know.: Transformers do NOT supply only + current, which I assume you mean as positive voltage, DC. So this is a power supply, not a transformer. Yes, you need an additional 36 volts DC power supply, and you would connect it as a negative supply, ie, connect the + output to your common or ground, and the – output would then be –36 volts for your amplifier. As to how, buy one or make one. Search google for 36 volt power supply. You will need to know the current requirements also.

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: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.: Thanks everyone for your answers. (I am using another acconunt) What I am asking in a nutshell, is basically will I be drawing so much power that I will get a $1000 + bill a month if I simply leave the transformer plugged in the wall. And I think I get it now, but there is still some tech talk I don't really understand. By the way, it is a 110V hardware, and I am living in a 220V country. So what you guys are saying is that there is still a NO LOAD loss, which means that the transformer is still using power even though my DVD player is not on. Is there any concern that the transformer would fry and malfunction if I leave it on say for 2 weeks plugged in. Note I am not leaving the DVD ON for 2 weeks, just the transformer. The DVD is off. I mean, there is still a red light next to the power sign on the player, as with most electronics, it is actually on stand by. Thanks.

Q:I have 12 x 12V 10W lamps in series would I be correct in saying I need a 230-12V 120W transformer to suit?: If 12 x 12V 10W lamps in parallel then it correct in saying that you need a 230-12V 120W transformer to suit

Q:Transformers are hot like boiled water. Will this be bad for a long time? How should i let it cool. The: Laptop Transformer Professional term is called power adapter. Power adapter heat is normal. Power adapter power conversion efficiency can only reach 75-85 or so, in the voltage conversion, a part of the energy loss, which in addition to a small part of the loss in the form of waves, the majority of the way out of the heat The The greater the power of the power adapter, the more energy is lost, the greater the heat of the power supply. The current power adapter on the market are using fire-resistant high-temperature plastic sealed package, the internal heat generated by the plastic shell mainly distributed out. Therefore, the power adapter surface temperature is still quite high, the maximum temperature and even up to about 70 degrees. The following are the same as the " Power adapter heat solution The power adapter heat is unavoidable, but it can speed up its heat to prevent its temperature from rising continuously. 1, the choice of small pressure drop, low loss of switching components, cooling area to be as large as possible, more than 100W switching power supply should generally have a metal perforated shell, or with cooling fan. 2, as far as possible to put the power adapter in a better place to ventilated heat, do not put things like books on the power above. 3, in a higher temperature environment, the use of notebooks, notebook power adapter should be placed in a place not exposed to direct sunlight and ventilation; do not put the power adapter in the notebook near the cooling outlet, or not only the power adapter heat dissipation is not Go out, but also absorb part of the heat.
