The application of the 370MVA/535kV 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 370MVA/535kV 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 370MVA/535kV 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:Why do I want Masterpiece Transformers so badly?!?
As long as it doesn't interfere with the important things in life, I don't see anything wrong with recapturing some of your youth with the toys you once loved. I mean, you (and I) *are* the target audience for the Masterpiece Transformers--at $100-$200 a pop, with fairly complicated transformations, and specifically designed to look like the G1 cartoon versions of the characters, these Transformers aren't for today's kids, they're for us '80s kids who now have disposable income and will spend the money for the definitive version of the G1 characters we grew up with. That's why we want them--they're made for us to want. :D Every guy has a hobby (and probably more than just one). Collecting fancy Transformers really isn't that different from, say, souping up cars, or putting together a home theater, or collecting Blu-rays, or whatever else guys our age are into. And besides, if you get over your Transformers bug, you can always sell or pass on your collection to someone else. Over the years I've picked up the Masterpiece versions of Optimus Prime, Megatron, Starscream, and Grimlock, and more recently I've sold off all of them except Optimus (yeah, I'm going to hang on to him); even though they were all loose, I actually wound up selling them for more than I paid for them new (that's how prized some of these Masterpieces are).
Q:About the transformer?
A 5% tap means that on the secondary coil there is a tap (a connection that leads out) 5% of the way up (or down) the coil.
Q:Please could someone assist on electrical transformers?
To improve the performance of a transformer, you have to:- [1] Reduce the copper losses, and [2] reduce the iron losses. Copper losses can be reduced by using copper wire of the highest purity; and by using copper wire that has the thinnest possible layer of insulating material on it. These measures, taken together, reduce the length of the wire and therefore its resistance. Iron losses are reduced by using magnetically soft iron in the laminations. This is the type of iron that has a tall and narrow hysteresis loop. Using copper wire with thin insulation (as mentioned above), keeps the windings close to the iron and so reduces magnetic leakage. A third measure is to use very thin laminations and to insulate them with very thin material as this will reduce eddy currents. It is very expensive to build a 99% efficient 250 MVA transformer. The losses in a 94% efficient version, are often cheaper to manage than the extra cost of making the 99% version.
Q:transformers or simpsons?
Transformers was pretty good. But it was kinda cheesy. Anything simpsons is good. SO i would say simpsons.
Q:transformers movie?
I agree, although a lot of people thought the movie was amazing, the real thing I liked abut it was the special effects, fight scenes, and Bumblebee! Who doesn't want a car that can turn into a robot? But yeah the storyline/acting wasn't that great, although there were a few times where i laughed.
Q:Should I get Transformers: Fall of Cybertron or Just Cause 2?
^^^ I disagree, Just cause 2 is just a bunch of flying around with your unrealistic/infinate parachute while shooting people. (Not that transformers is realistic) but still. Just cause 2 will bore you to tears i kid you not.
Q:Why can autotransformers be used as safety transformers?
The high and low voltage side of the autotransformer is realized by tapping in a coil, and there is no magnetic connection between the two times and there is an electrical connection, so it can not be used as a safety transformer. Isolation transformer high and low voltage coil is separated, the only magnetic connection between the two there is no electrical contact, so the role of security protection.
Q:On the transformer problem
When the primary voltage of the transformer is rated voltage, the secondary voltage does not decrease with the load current, but this is only the case where its rated power is not exceeded, and the magnetization will increase when the secondary current increases Paul its current output, a power beyond its maximum, the secondary current increases the voltage will drop until the fever burned. Inrush Current 1 Overview Transformer is based on the principle of electromagnetic induction made of a static electrical appliances, for the low voltage into a high voltage or high voltage into a low voltage, AC transmission and distribution system is an important electrical equipment. When the transformer is closed, it may produce a large current, this paper mainly discusses the current generation and influence.
Q:Who Loves Transformers??? and when is PART 2?
Transformers actually exceeded my expectations. IT WAS AWESOME! :) The second one has so far been scheduled for June 26, 2009
