Description

The application of the 40MVA/110KV generator startup/standby transformer, 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 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 40MVA/110KV generator startup/standby 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 OLTC 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 OLTCTransformer’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 40MVA/110KV generator startup/standby 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 OLTC Transformer products.

Q:I want you guys to tell me if the movie transformers its a good movie or not? Why?Thanks, See Ya!: The Transformers was a marriage of two of the biggest Blockbuster Producers in the business today.Speilberg and Michael Bay (Bad Boys, Armageddon, The Rock)So expect Mind Blowing effects thanks to what Bay Brings to the table and Speilberg brings to the table a relentless perfectionist approach to all of his films.Having said this. If you are a die hard Transformers fan, you'll revel in homages paid to the original animated movie and TV series Optimus Prime's Voice is done by the same man who did the voice for the original character If your not a fan, you'll get a believeable display of vehicles shifting into 15-30 foot robots. The robot effects are stellarthe action sequences are dizzying they happen in rapid succession. The quirks in the characters are really what make the movie shine. From the military personel to Anthony Anderson's portrayal of a high strung, know-it-all hacker the characters really sell the drama. Shai plays his character to the hiltreally no suprise why he's Speilberg's next it boy. The chemistry between Him and Fox is realnot forced and contrived (see Affleck Tyler in Armageddon) There were scenes in which they made the Autobots (the good robots) Less than menacing trying to communicate with todays lingo/slang learned from the world wide webOne of the cleverist twists I think was the way they had Bumblebee communicate through song lyric via the radio Great Soundtrack.great acting (for the most part) If I were to rate Transformers on a scale from 1-10, I would give it 8.5. It does what it was meant to do very well.entertain. Worth the $20 to buy it or the $5 to rent it.watch it a couple time to catch all the little hidden twists and hits in the movie

Q:I need x-mas gifts for transformer toys! Please help thank you!: I need x-mas gifts for transformer toys! U R giving gifts to Transformers toys?, Just go to any Wal*Mart, Target, KB Toys store they have lots of Transformers toys. They have a lot of selection @ Toys R Us(2007 movie, Beast Wars, classic, Energon and more)

Q:I just saw the movie and im still trying to take in all that just happened. It was pretty awesome, and for me being a transformers fan since i was little (im 17) i got really connected to the characters. other viewers just familiar with the movie might not feel the same way. like when ironhide was killed, i was like hellll no wtf just happened. i was so mad. And when sam killed my all time favorite character starscream. I was so upset that he died that way. Just curious of your thoughts on the movie and if you think there will be a 4th. (i think so but not for maybe 4 or 5 years). Even though they killed off starscream,ironhide, megatron, etc. They can always come back as galvatron and all that, plus theres still unicron thoughts?: Michael Bay already said he wasn't going to make a 4th one (I think) Anyway, I was definitely pissed when Ironhide died. I've been writing fanfiction on Fanfiction for years, and you get connected so easily with the characters, and right now, Transformers is my main thing to write about. I thought the movie was awesome. Truly epic. It was so sad when Wheeljack (Known as Que in the movie) died. He was so innocent. Just your typical engineer/scientist who was doing his job and how he died was really heart wrenching. I did cry when Ironhide died. Like I said, you get so connected to the characters when you spend years writing about them. I hope Bay changes his mind and makes more Transformers movies. I'd definitely watch them!

Q:i have this audio transformer (about the size of a bottle cap) with three prongs on one side and two on the other. i am completely mystified by this configuration. how would i (say for example) hook up this transformer to a 9v battery in order to increase voltage? thx: 9v battery has a D.C. and a transformer only work in A.C. circuits.

Q:If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts? Please help, thanks so much!lt;3: You asked the same question before. Here is the only correct answer again. There is actually a phasing to the transformer windings. If you connect them in series with the phases adding (both hit + 12 at the same instant) you get 24 volts out. If you connect with the phasing wrong (one hits +12 while the other hits -12) and put them in series the output will be zero volts (and they might overheat). If you connect them in parallel with the right phasing you will get 12 volts and the amperage will add to give you the sum of their amperage. If you connect in parallel with the phasing wrong you will get zero output voltage (and the danger of overheating). If the transformers do not make their phasing clear put a voltmeter on the output and briefly turn on the primary while seeing if you get zero or the voltage you want. If the phasing is wring swap the wires of one transformer around and check with the meter again. As long as the phasing is correct there is no problem with either series or parallel. A lot of commercial equipment is made with two low power transformers because two smaller ones are often cheaper commodities to buy than one special-order larger one.

Q:the use of autotransformers is strictly prohibited.: Double-winding type safety isolation transformer load side and the power supply side is not electrically connected, is safe, and autotransformer primary shared a winding, it has a direct electrical connection with the power supply, unsafe.

Q:I want to step down a 240Vpeak signal to 24. Anyone know where I can get a transformer to do this? Also does frequency have a dependence on a transformer? The signal I am looking at has around 55Khz frequency. Thanks for your help: You won't be able to find a transformer for that frequency, unless you are lucky. You will have to wind your own. Probably a ferrite core is best, depending on your power level, which you did not mention, and is an important design factor. If this is a very low power signal (you do use the word signal), perhaps a capacitive or resistive voltage divider will be enough. Or search for an audio signal transformer. .

Q:Why the provisions of the maximum temperature of the provisions of the transformer 65 °?: Transformers and other electrical equipment temperature limit is determined by the level of insulation materials. Insulation grade refers to the heat resistance of the insulation material used, divided into A, E, B, F, H grade. Allowable temperature rise is the limit of the temperature of the electrical equipment compared to the ambient temperature. Insulation temperature class A grade E grade B grade F grade H grade Maximum permissible temperature (° C) 105 120 130 155 180 Winding temperature limit (K) 60 75 80 100 125 Performance reference temperature (° C) 80 95 100 120 145 In the electrical equipment such as transformers, the insulating material is the weakest link. Insulation material is particularly susceptible to high temperature and accelerated aging and damage. Different insulation materials have different heat resistance, the use of different insulation materials, electrical equipment, the ability to withstand high temperatures are different. So the general electrical equipment is specified in the maximum temperature of its work. You ask the question, the top of the oil temperature does not exceed 65 ℃, is in the case of rated load manufacturers consider a variety of factors to ensure that the insulation material is not damaged by the temperature limit. Under normal circumstances the top of the transformer oil temperature is the highest.

Q:I realize this may be super simple but i cant for the life of me figure out how to open a wall mount transformer it seems like they are snapped shut with no way to open?: They are glued, or even sonically welded. They are made to be replaced not repaired. They can be open by sawing a knotch in the corner and prying open with a screwdriver.

Q:I fried a transformer in my lathe. I went to the electrical supply near my house and the got me a new transformer and said it will work. The old transformer is 3 times bigger. they are both 100VA. the voltage on the original is 230v in and 100v out. It powers the on/off switches for the forward/ reverse micro switches. from the micro switch it powers the magnetic puill in for the contactors. The contactor say 100V.will using a 110v transformer cause and problems or issues?Should I return the one I purchased and order a 100V ?I have work piled up and waiting and really need this lathe operational ASAP.Thank You in advance for any information.Earle: You ALSO need to be concerned with the POWER RATING. The bigger transformer is capable of handling more power (current) than the smaller one. Therefore, even though the VOLTAGES are correct, the smaller transformer will over heat and burn out, POSSIBLY CAUSING A FIRE! There should be a CURRENT RATING on the old transformer (like 5 amps or 10 watts), and you need to get a new transformer that has BOTH the same VOLTAGE AND CURRENT capabilities.
