Description

The application of 300MVA/ 230kV export America phase-shifting 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 300MVA/ 230kV phase-shifting 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 300MVA/ 230kV phase-shifting 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:if i take a small transformer meant to be used at 120v:9v 60hz, and discharge a 360v 100uf capacitor (or similar) into the 9v winding, will i get a high voltage pulse on the 120v winding?: You just described a frequently-used principle. Don't tase me, bro!

Q:does anybody know what Transformers 2: Revenge of the Fallen is going to be about? Like what is the whole plot, or storyline?: The battle for Earth has ended but the battle for the universe has just begun. After returning to Cybertron, Starscream assumes command of the Decepticons, and has decided to return to Earth with force. The Autobots believing that peace was possible finds out that Megatron's dead body has been stolen from the US Military by Skorpinox and revives him using his own spark. Now Megatron is back seeking revenge and with Starscream and more Decepticon reinforcements on the way, the Autobots with reinforcements of their own, may have more to deal with then meets the eye. I'd take that with a pinch of salt though as it's probably fan invented.

Q:I am doing a school project of a Wind Turbine; and I need to show a transformer or what a transformer is in a wind turbine. I have just 1 question. WHY DO PEOPLE USE TRANSFORMERS?: Kiran okorder

Q:I LOVE TRANSFORMERS. From the box car days to beast wars. I played ROTF when it came out, it was pretty cool. Then WFC, epic. Now I'm wondering if I should get Dark of the Moon. I don't wanna get it and find out that people don't even play online. Or come to find out that this game is super weak and such. I just like the feeling of attacking then transforming into a jet (Starscream) and flying away. For you transformer fans, is this game a buy or Spend that money on another game situation? Tips and suggestions would be nice. Thanks!: Transformers Dark of the Moon is supposedly like Transformers WFC, it has the same concept, like the transformations, the guns and driving around, so I guess I can say is, if you really liked/loved Transformers WFC, then you should pick up Transformers Dark of the Moon, but watch out. it might be a little bad

Q:First of all, try not to be bias ;). My birthday is on December 19th, exactly the release date of the Transformer Prime, which is a great tablet, one I think surpasses even the iPad 2. With Steve Jobs gone and the new quad core installed in the Prime, would the iPad 3 be likely to be better than the Prime? Should I just wait for an iPad 3 if so? Thanks :)!: no

Q:I need a (step-down) Transformer of the following specifications:240VAC to 24VAC 10A or 240VAC to 24VDC.(Output as 24VDC would be better/easier).I live in Victoria, Australia and need one ASAP (next 3 days or sooner)Plz tell me any store or so Also, if u wanna know the VA Rating, its 240VA.If 10A is not available then anything closest to it. say 9 or 8.5 or 8 or 6.5.Cheers!: Transformers only work with AC, so the second choice is not possible. But you can buy power supplies that have a DC output. Reference has one possibility. Search google for buy supply 24v 10a and you will find lots more. .

Q:Hi there.I have purchased a Stepdown Transformer so i can use a Record Cleaning Machine I am buying from the U.S.It uses a powered suction unit to clean the record.All transformers for use with American equipment have 110v output, but i think your equipment is usually 120v.in I have been told that there is nothing to worry about as 110v out on the transformer is enough to power the equipment connected to it .Our AC output in Australia is 240v but we can use any voltage from 220 to 250. Therefore 110v should be enough.can anyone clarify and tell me it should be ok.Thanks a lot in advance.: Electrical appliances are designed to tolerate the range of voltage. Here in the USA the terms 110 and 120 are used interchangeably as are 220 and 240. Good luck mate!

Q:hi can anyone tell me when installing/replacing a door bell transformer when switching off power supply at main source will that make it safe to work with the connections, it keeps telling us to turn fuses off well it dont have fuses its a circuit breaker. so do we turn circuit breaker off asweel as main supply into house. may be a silly question to ask but dont wnat any trips to A nad E lol thanks guys xxx: Friedland Transformer

Q:Here I am building prototype transformers for testing, using 1 ft length aluminum conductors of 1/2 by 1/2 inch width square conductors. I am structuring the (aluminum square tube)windings(connected at corners by ordinary round copper wire) in return layer diagonals, ( the pattern set by odd magic square sequences) to establish maximum internal capacity in the windings. If the current in the windings is opposite between every internal lateral square facing, most of the external field around the windings is cancelled, but internally between the windings the magnetic loops will be in unison. I therefore wish to put insulated steel tube sleeves around the internal aluminum loops of the wiring array, for a very unconventional honeycomb type core transformer. I should be able to measure for eddy current output on any steel sleeve by shorting the ends of the outside steel segment with an amperage meter. A conv. secondary will also need copper loops wound lengthwise around the steel.: An AC transformer connects AmpereTurns in the Primary to AmpereTurns in the Secondary using the time varying magnetic field in the core. The maths for the size of the core is well established. If you double back on turns they do not count as part of your ampereturns - unless you shield the doubled bit. Such methods are used in shaded pole motors. The only way to lighten the Tx is to use higher frequencies in the core. This 'dumps' the magnetic energy into the secondary more often so you can use a smaller core (bucket of energy!) The magnetic field is always perpendicular to the current and hence so are the core loops (in a Vector Notation sense - not necessarily physically) If you introduce Iron windings in the windings space you will get bigger Ohmic Losses. I hope this helps - you obviously have a plan to make hyper-efficient Tx but they are already near 0.999 efficiency.

Q:I have a DC current transformer and it is a 2500:1. I do not know what this means but I have a rectifier hooked up to it and am measuring the output DC voltage. I have hooked up resistors in values of 20Ω, 2kΩ, 10kΩ, and 20kΩ. I do not know how to convert to amperes though the resulting DC volts. How can this be done?: Your current transformer at 2500:1 means, 2500 amp flowing through bar primary, (Which passes through the centre of the coil) will produce 1 amp in the coil, but it will not be DC. The CT will have a VA rating. You would have to put 2500 amps through bar primary to achieve 1 amp on secondary winding. This is in the power generation/distribution sector. It's what is says on the tin, A current transformer. The voltage output would be minimal. To find this, you would need to measure the AC voltage at 2500 amp through bar primary, or find the number of turns on the coil and/or the voltage drop on the primary bar as it passes through the coil. Primary volts per turn Sec volts per turn.
