Description

The application of 500MVA/765kV substation auto-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 application of 500MVA/765kV substation auto-transformer. In order to make the products applicable to any substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity 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 500MVA/765kV substation auto-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:High school physics, according to the transformer U1 / U2 = N1 / N2 Can make a large voltage into a small voltage, but the small voltage can become a large voltage? Need no conditions? Can the transformer be used only for alternating current? I am now only high school physical level, answer not too esoteric or too professional! Thank you !!: Transformers, by name, can change the voltage. Change is certainly not directional, and if you can put the voltage higher, then you can also make the voltage smaller. As long as the input and output side of the exchange, you can make the voltage larger or smaller. But some of the voltage is specified, only buck or boost. Because it has a one-way circuit. transformer:

Q:I am an avid stop motion animator, and I have been looking for Transformers toys to buy and animate. I have one, Deluxe Class Cliffjumper, and he's really great, pretty much the same as Deluxe Class Bumblebee. He works very well for stop motion. He transforms great, he looks cool, he's got good feet, he has stiff joints, and is very flexible and poseable. But I've been looking for another Transformer toy that can do the same job. So far I've bought two, and they have not been the same quality. I bought Deluxe Classes Barricade and Bonecrusher, but Barricade was too flimsy and Bonecrusher is too top heavy with terrible feet for poseability. Anyone familiar with the Transformers toys that could give me any ideas for the better toys for animations? (Under $40, please.) Thanks!: Do you mean the monster will say rates as he kills, or do you mean the full soundtrack would be rates. So, if he have been to have a communication, all of his communication may be sampled from different video clips? If it is the later subject, then i might propose getting Jack Nicholson video clips. His voice is so creepy and he has made maximum of flicks, you have have been given to be waiting to come across something you will need. If it is the former (the place he's in basic terms quoting type video clips), i admire: Wait'll they get a load of me! Jack in Batman right this is Johnny!

Q:I I am looking to buy a 208 to 480 transformer, would I simply buy a 480 to 208 and reverse the input and outputs? it's a 3 phase system and it is being supplied by an 80kW generator, then straight to an ATS to switch power from normal to emergency.: Yes. Just don't put much over 208 v to the 208 side. I wouldn't try using it at rated capacity though.

Q:I want to run a electric motor at 6v from a wall outlet. I need to know what wall plug transformer rating I should use to run it. Here is what I have.: It okorder

Q:2500KVA transformer rated current 3608A, how much can be overloaded current?: 2500kva is the transformer capacity, P is active, COSφ = active / capacity. 0.8 = active / 2500 that active = 2000KW and because of active = 1.732 * UICOSφ and u = 0.4V, COSφ = 0.8 into the equation of current = 3608.5A.

Q:Hey!I Love Shia Labeouf I Was Wondering If Transformers Was A Good Movie I Haven't Ever Got A Chance 2 Watch It. Is It Worth Watching? These Are Some Of The Films I Like.Pirates Of The Caribbeanthe Dark KnightSpider man 3 Home Alones Mean GirlsThnxxP.S. I Heard Theres Going 2 Be A Transformers 2! D: Transformers is one of my favorite movies. I loved it. It is action packed and Shia Labeauf is brilliant in it. You will love it. Transformers 2: Revenge of the Fallen will be out next year, so Rent Transformers!!!! It's out June 26, 2009!!!

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!: i love transformers also, i have borderlands one and the first transformers, get border lands because it is harder to beat and you can make as many charecters as you want and it has a longer story, youll get more for qwhat you pay for if you buy borderlands 2

Q:can the amps rate be increased by using transformer from 10amps to 120amps.: If you mean a 10 amp transformer, I hope you like the smell of burning insulation. However, you could re-wind the transformer to use one twelfth the number of secondary turns, using wire with twelve times the cross sectional area.

Q:I am looking for a 220v transformer with these secondary voltages: 2x13v, 1x9v, 1x3vIt has to be at least 20va.I cant find this anywhere :/: Transformers with odd voltages, specially with 4 windings are not really available. You need to find a different way to do whatever it is you need. Or get one custom made, expensive. One alternative is to get a 220v 100 VA transformer to, perhaps 12v, and remove the existing secondary, counting the turns. Say you count 20 turns. Then using smaller wire, wind two windings of 22 turns each, for 13 volts, one of 7 turns for 9v, one of 5 turns for 3v.

Q:I have a 120v X 24v step down transformer that is capable of supplying 30 amperes. I need to convert the output to dc to supply a project I am working on. I have a bridge rectifier capable of handling 10 amps continuously, but nothing that could handle the 30 amp output. What would occur if I put the rectifier on the input side (with no filter capacitors) and fed the xfmr the DC voltage with 120hz ripple? I suspect the xfmr wont like the 120hz input and generate excessive heat. Anybody know for sure? The xfmr has a laminated iron core and copper windings.: You are asking some strange questions. You do not have a very good understanding of transformers. A transformer ONLY works with AC. This is why Tesla argued for AC being supplied to houses. With a simple transformer, the voltage could be increased for less loss on transmission lines and then with a step down transformer, the AC could be brought into homes. Edison, on the other hand, loved DC and wanted all houses to be supplied with DC. Edison, in an attempt to prove Tesla wrong, invented the electric chair to show how dangerous the larger voltages would be. Edison even electrocuted animals in his electric chair to demonstrate the effects of higher voltages. Fortunately, Tesla won the argument, or we would not be able to transmit electricity over high power lines from generators to homes. Now, a rectifier in the strict sense, does not change AC to DC (with ripple) but simply reflects the negative wave to make it positive. Thus adding a DC component and doubling the frequency. The DC component will simply pass through the transformer (no heating) and the higher frequency will work just great with the transformer. In fact, you can make smaller transformers by using higher frequencies. This was a technique that Sony used many years ago to make great amplifiers and Fisher and Paykel use to make better appliances. (Other companies might also, but I am not aware of them.) So, your transformer will only see an input of 60 V AC and step that down to 12 V. Thus, you will not have the 24 v you need. Why don't you get a better bridge??
