The application of 334MVA/500kV single-phase OLTC auto-transformercan 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 the334MVA/500kV single-phase OLTC auto-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 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 334MVA/500kV single-phase OLTC 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:Do electrical transformers protect the surrounding wires from power surges?
No, the transformer itself wouldn't ground it. I don't know if they have some kind of surge protector, by the transformer would just 'pass it on' (most likely blow a fuse if the trannie survived
Q:how to use a transformer (electrical)?
There is no reason why the higher output supply would draw more current. The input current to the supply is indeed proportional to the amount of power consumed on the other end. In addition, it is even possible that the new power supply might be more efficient, and use less power if you get a good one. Look for one that has a Green certification. One power supply can be more efficient than the other. No power supply is 100% efficient. For instance, if your PC needs 90 watts and your Power supply is 90% efficient, the supply will need to draw 100 watts from the AC mains. In any case, I don't think you will be using any more energy with the upgraded supply, perhaps even less, and your PC should even run cooler.
Q:Transformers 2 question.?
The movie is called Transformers: Revenge of the Fallen. It comes out June 26th. Decepticon forces return to Earth on a mission to take Sam Witwicky prisoner, after the young hero learns the truth about the ancient origins of the Transformers. Joining the mission to protect humankind is Optimus Prime, who forms an alliance with international armies for a second epic battle.
Q:transformer - install in electrical box only?
you are going to be able to desire to get the 24 volt administration transformers. they are type 2 (this skill that if the wires get shorted the capability output is going down and you are going to be able to't have a fire began by skill of the quick). they generally contain a installation it is made to pass interior a knockout with the line voltage wires protruding interior. The transformer itself stands proud and has screw terminals for the low voltage area. different styles of transfomers won't meet the code using fact they pose a fire possibility.
Q:What are the lyrics to the Transformers theme?
Whoa she just gave you the best answer!!
Q:Flyback transformer usage?
A 'flyback' transformer won't do anything but blow the breaker if you plug it into the wall. They're designed to run at 15,750 Hz. and yes, they do couple a 'sawtooth' waveform out to the horizontal deflection coils of the 'yoke' around the base of the CRT which deflect the electron beam to produce an image. If you want some -great- sparks, go out on the 'net and look ou plans for a 'Tesla Coil'. I've built a couple of those that would draw an arc several inches long. And since they're very low-current (on the secondary side) they're quite safe to play with. HTH, Doug
Q:help with transformer problem.?
this is quite a typical question. there will be many examples similar to it
Q:Does anyone know what the movie was without a name on the transformer previews?
Yes. okorder
Q:2 Electrical Transformer Questions?
1. Transformers don't usually have plugs on them. 2. The word you want is solder. Tape will work, but it is sloppy.
Q:How come Transformers has made more money than Star Trek, Wolverine, Terminator, etc movies that have been mad?
Transformers hits a large demographic. Since it is based on a toy from the 80's adults who grew up in the 80s want to go see it. In addition to that, the movie has Megan Fox in it. And as we all know she is attractive, and who wouldn't pay 15 bucks to watch her run around for 2 hours. Plus the movie rocks!
