Description

The application of the 720MVA/550kV main 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 the 720MVA/550kV 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 the 720MVA/550kV 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:Transformer ONAN?: This is the transformer cooling mode of the sign, meaning that the internal insulating oil natural circulation, with the external air natural heat transfer.

Q:everyone's been fighting about if jazz from transformers is white or black i think he's just white pretending to be black what do you guys think: Jazz is always voiced by an African American actor, Scatman Crothers, Darius McCrary, Phil Lamaar, but even though Transformers have varying ethnic voice actors, or for some reason, a human foreign accent, they're one race and not considered white or black, or foreign no matter what part of Cybertron they come from. They're either Autobot or Decepticon, and they're allegences, not races. They're Cybertronian by birth, Decepticon is a faction name created by Megatron, and Autobot is the governing force later changed to the title of the good guys amidst the war. I think it's just tradition for Jazz to have a African American voice and sound cool on acount of his name

Q:Transformers are divided into several. What is the role of each? To be specific!: Transformer is the instrument that regulates voltage! Transformers can be classified according to their operating frequency, use and core shape. (1) Classification by operating frequency Transformers according to the operating frequency can be divided into high-frequency transformers, IF transformers and low-frequency transformers.

Q:A transformer consists of 250 primary windings and 838 secondary windings. If the potential difference across the primary coil is 25.5V , what is the voltage across the secondary coil ? If the potential difference across the primary coil is 25.5V , what is the effective load resistance of the secondary coil if it is connected across a 135Ω resistor?: Transformer equation, N_pV_pN_sV_s V_s (N_p V_p)/N_s, plug in the numbers and calculate. N_p/N_s sqrt(Z_p/Zs)

Q:I'd recommend a big Transformers fan for this please. So I have a Transformers series that I'm working on for fun, and I want an awesome name for it. It has Unicron in it and the Autobots and Decepticons team up to take him down. A name for that part is Cybertron Alliance. But I also need a name for story with events that take place before that, when the Bots and Cons were at war. Please help!: You can't do that, you didn't make Transformers. Michael Bay would have asked could he add some of the characters into his movie. Like they would have asked J.K Rowling could they do Harry Potter Movies.

Q:How does a step down transformer decrease the output voltage but increases the output current? And how does the step up transformer does the opposite thing?: that one you have to ask the energy saver I think they have the solution.

Q:I bought my first ever Transformers toys which are the movie line, Ironhide and Barricade. However it is noted on the side of the box classes name; Voyager and Deluxe. What is the difference between both? I've search around the internet but none has given definitive description about it. All I know is that there is Deluxe, Voyager, and Leader class, and some more lower grades.Does the classes defines scale, size and complexity of the transformation?: For the best answers, search on this site

Q:I need a transformer that can produce 10 volts from a 1/2 volt change in the primary winding, but don't know how they are classified. The transformers I've seen on the internet give no clue of the winding ratio, just a serial number. Thanks.: Your question makes little sense as listed. Transformers are not usually used to amplify 1/2 volt variation. We need more detail.

Q:I need to find a transformer that will convert 480 input to 240 output for a motor controller. Where can I get this type of transformer? I've only been able to find 120/240 transformers.Thanks.: Check with a supplier who sells industrial/commercial transformers and other electrical equipment. There should be one in your local yellow pages, or online. You will need to know what kVA rating is required for your motor as well.

Q:Transformers are hot like boiled water. Will this be bad for a long time? How should i let it cool. The: I bet, your power certainly no my hot ,,, my power is my friend's hottest, But you do not have to, but it is normal ah ,,,, different brands, the temperature is not the same .. Generally good power are temperature control, to a certain temperature to turn off the power, I was like this, do not worry But do not plug in the socket for a long time, and will burn the power, and there is easy to thunder in the summer ,,, will burn out ...
