Description

The application of the 400MVA/230kV power 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 400MVA/230kV power 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 400MVA/230kV power 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:1000KVA transformer power loss is how much: Transformer no-load plus stray loss is fixed, usually 6% of the total capacity, load loss that is copper loss, according to the load power, and power factor calculation

Q:I have a few power tools, none of which are natively wired for 110-240v. In particular, a portable table saw, a router, and a mitre saw, all at 220v. Since the resale value of them are so low on auction sites, I was thinking of taking them with me when I shift home to the states. Would it be safe using those tools, for extended periods, whilst running them on a transformer?: You can do that. Just make sure the transformer is rated for the power they will draw. Keep this in mind: American homes are wired with 220 volts. Only, they split the voltage into two 110 volt legs. Each leg to ground (or neutral) is 110 volts (also commonly referred to as 120 volts). But from one leg to the other is where you get the 220 (or 240) volts. My garage is wired with two legs of 110, which means I have 220 out there. I also have an outlet for 220 volts. Because some of the power tools I run demand more current, and run them simultaneously, the standard 110 outlets struggle to meet the demand. So what I did was to take a dryer cord and wire it into a pony panel where I can draw 110 volts from one leg to ground to power a table saw while the other leg powers the dust collection system. To try and run both those pieces of equipment on a single 110 line means a trip to the breaker to reset it because each draws enough power that when used together they draw more current than the circuit is safely rated for. YOU can do something similar. Just make sure you use a 20 amp outlet meant for use with 220 volts and wire into the panel (if not already wired) and set up a 220 volt plug where you will be using these power tools. Using a transformer will work, but the more you couple the power magnetically the more inefficient your system becomes, and you waste power. Also consider just buying tools rated at 110 volts. They're plentiful and cheap enough that the cost may offset the cost of shipping these 220 v tools. Throw in the cost of a transformer and you're probably spending more money in the long run. Hope this helps. '')

Q:I live in Market Weighton and I need to know why my local electricity transformer is. Where will I need to look?: For residential, the step down transformer for home electricity use is typically a pole top mounted transformer. It may be at the top of a power pole near your residence. Sometimes there may be a pad mount transformer (square metal box) near your home that is used. You may want to look outside your home, and see where the wires coming into your electrical service are coming from. That should tell you where the transformer is. If you live in a newer neighborhood, you may have underground service ( thus no power poles) and the transformer may not be visible. It would likely be close by in an underground electrical vault. There is a picture of a pole top transformer in the attached article below:

Q:can i use 12VAC 60w transformer for 12VAC 30w (3 10W) light?: Yes. 60 watts is the MAXIMUM you can use with that transformer.

Q:Usually the life of the transformer is called 20 years, is there any GB requirements? If there is a specific in that standard inside. Thank you for your thanks: 3, this life is in the case of rated operation (rated capacity to run). How much time is the transformer running? So in normal circumstances, this 20 or 30 years is fully able to do. 4, now, how many transformers are life and scrapped? Often the life cycle has not arrived, the transformer is eliminated. The reason is: 1) economic development is too fast, the transformer to increase the capacity, and to replace the transformer. 2) Transformer technology development fast, power transformer almost every 3-5 years out of a new product, the loss is also constantly in the drop. For these reasons, the transformer is less than 20-30 years to be updated. So no one is very concerned about this life. Guidance of the national standard for you - Guidance on the load of oil - immersed power transformers GBT 15164-1994. Transformer machinery industry standard GB / T 17468-1998 "power transformer selection guide" in Article 8 transformer thermal aging rate and life of the "transformer life is generally 20 years."

Q:I love the movie transformers and cant wait till part 2.Anyone know anything about it specifically???: I cannot STAND that movie. The live action version sucks so much c0ck and balls. The original 80s Transformers Movie animated version had WAY more robots and WAY more action. Mike Bay's piece of cinematic fecal matter had only a small group of robots who look NOTHING like the Transformers from the cartoon series, and it was all about that idiot Shia LeBeouf running around whining and acting like beyotch. Correct me if I'm wrong, but I paid to see a Transformers movie and got ripped off. The movie wasted my time with those stupid human characters, and the robots really didn't do much of anything. The story sucked and who actually gives a crap for Shia's character romantic life? Ugghh! What a turd of a movie painted and glamed up to look better than it actually was. Which is why I don't undertsand why people like this movie so much? It is an insult to the true Transformers fans.

Q:i want what does a transformer exactly do and not how it works: A okorder

Q:Does anyone have any knowledge or experience with what happens if you try to run two different power supply transformers from the same AC line input. Can you do that? I have one transformer with a primary DC resistance of 28 ohms. I have a second transformer with a primary DC resistance of 265 ohms. I want to run these two transformers from the same AC power cord input. I tried connecting their primaries in series across the AC cord input, and the resulting secondary outputs from both transformers were lower than expected for a no-load condition. I am a little concerned about trying to connect the two transformer primaries in parallel.Any ideas?: I do not see any problem in having them parallel,provided the input power is sufficient.

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?: Cloverfield, which revolves around a monster attack in New York as told from the point of view of a small group of people, is being produced by J.J. Abrams. It is being directed by Matt Reeves, who co-created Felicity with Abrams, and is written by Drew Goddard, who has worked with Abrams on Lost and Alias. The movie, which is believed to have a relatively modest budget of about $30 million, began shooting in mid-June in New York. With Transformers generating huge tracking numbers in the weeks before its release, the studio decided to put footage from Cloverfield in a teaser in front of Transformers to build buzz. Cloverfield might just be a working title though. It is still being shot in New York.

Q:Transformer Uk = 4.5% What does it mean?: The short circuit impedance of the transformer is related to many factors of the transformer. Such as transformer capacity, loss, internal coil structure and so on. But once the transformer is manufactured, it is the same. Short-circuit impedance is a very important technical indicator for the user. Such as the stability of the power supply system, the quality of the power supply, the transformer in parallel after the safety and reliability, and so have a relationship.
