The application of the 50MVA/220KV SF6 Bushing startup/standby transformer, 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 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 50MVA/220KV SF6 Bushing startup/standby 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 50MVA/220KV SF6 Bushing startup/standby 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:Gundam Seed vs. Transformers?
What, in a battle or as in an anime? If it's anime, I pick Gundam. If it's a battle. Well Transformers got someone called Unicorn who's the size of a Planet. So you can imagine how powerful he is.
Q:Transformers 2: Revenge of the Fallen?
I think its again about the cube
Q:What is the difference between transformer and a coil?
A transformer is two or more coils that share the same magnetic flux path. In an ideal transformer (every bit of flux caused by current through one coil circles every turn of that coil and also circles every turn of all other coils in the transformer), every turn of all coils shares a similar induced voltage that is proportional to the rate of change of that common flux. Two coil transformers have the property that the power going into one coil will exit the other (except for copper and iron losses). Since power equals voltage times current, and volts per turn are all the same, a transformer with half as many turns on the output winding (secondary) as there are in the inlet winding (primary), will output half as much voltage as is applied to the primary, but will output twice as much current as goes through the primary. That way, the product of voltage times current going in equals the product of voltage times current going out. -- Regards, John Popelish
Q:What is the transformer capacity ratio? Capacity than 100%.
Have not heard, you say is not the main transformer parallel run between the main transformer and the capacity and capacity of the ratio, or the meaning of such I made a change, you say is not: the transformer once measured capacity can be transferred to the secondary side or three times, such as three winding 50000KVA main transformer, 100/100/100, is the primary capacity can be all to the two Secondary use, you can also use all the three times, which is mainly and the main transformer winding, clip and so on factors
Q:Why do people use transformers?
A okorder
Q:Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:is pole mounted transformer emf harmful?
No. The level of EMF is dependent on the current flowing through the wires. The higher the current, the higher the magnetic field. The strength of the EMF also decreases with distance. The pole is at the edge of your lot and the transformer is probably 20' in the air. In reality, high load appliances in your home are much closer to you and your family. The EMF fields measured next to a toaster, microwave oven, electric range, or electric blanket are far higher than you'll likely measure standing below the transformer. In October 2000, Discover magazine published a list of the 20 Greatest Engineering Blunders of the past twenty years. EMF made the list -- Below is the text and a link to the official article. Currents That Don't Kill: The Clinton administration estimates that American taxpayers have paid $25 billion to determine that power lines don't do anything more deadly than deliver power. In 1989, Paul Brodeur published a series of articles in The New Yorker raising the possibility of a link between electromagnetic fields and cancer. Eight years later, after several enormous epidemiological studies in Canada, Britain, and the United States, the danger was completely discounted. All known cancer-inducing agents act by breaking chemical bonds in DNA, says Robert Park. The amount of photon energy it takes is an ultraviolet wavelength. So any wavelength that is longer cannot break chemical bonds. Visible light does not cause cancer. Infrared light is still longer, radio waves longer still. Power-line fields are preposterous. The wavelength is in miles.
Q:Asus Transformer Pad TF300 good for school?
(warning : poor English) Yes, Transformer Pad TF300 good for school. 1. It have a keyboard (optional), you can take notes faster. 2. Likes all others (pads), there have camera, you can take a photo of the board (if teacher allowed). 3. TF300 battery life quit good, with the keyboard even better. 4. We will work in cloud computing in the near future (or now) mostly. Google drive meet your needs for word processing, drawing, creating simple spreadsheet. you can share your works, or finish your project collaboratively with your group members via internet. 5. the chips: Tegra 3 is responsive, the screen: 10 (1280x800) is comfortable, the OS: Android 4.0 is more suited for tablets and it's a better os overall, the brand: ASUS, manufacture the best Android tablet (imo).
Q:Transformer copper row selection
Selection principle of transformer copper Meet the load requirements; Transformer corresponding to the rated current in accordance with 1.1 times the overload factor to consider; To meet the safety distance, and components aligned; Satisfy the dynamic stability. Transformer copper selection considerations The choice of copper can not just consider the current carrying capacity it also consider the maximum short-circuit current size, that is, consider the choice of a copper after the most short-circuit when the short-circuit current short-circuit the size of the current matching the size of the protection (that is, Relay protection value size).
Q:How much can you increase current with a transformer?
this is not a contradiction. the skill keeps to be an analogous (minus some inefficiency). If the skill in is a million Volt at 1Amp, that's a million Watt (Volts situations Amps equals Watts). After dealing with a 2:a million step up transformer, the output would be 2 Volts at a million/2 Amp a million Watt. it may be mind-blowing to get extra skill out, yet that's only not the way issues artwork.
