The application of the 270MVA/525kV single phase 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 270MVA/525kV single phase 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 270MVA/525kV single phase 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:House near a polyphase transformer?
Poly-phase transformers which are merely 3-phase transformers don't really cause anymore interference than any other transformer. If the thing was up against your wall, then maybe it would mess with radio or cell phone communications, but really your main interference concerns would be if you were near high voltage transmission lines. Why not ask the previous owners or neighbors in the area if this transformer has interfered with their electronics.I doubt it.
Q:12 VAC 60W Transformer?
Transformer rating is 60 watts ~ don't use total wattage over that. So with your three 10 watt bulbs, that totals 30 watts. Will be okay. You can actually use up to six 10 watt bulbs, or a total of 60 watts max. Been using light bulbs for 65 years !
Q:Which Autobots and Decepticons r going to be in Transformer-2?? Any ideas?
Soundwave. Optimus Prime 3
Q:Old transformers tv show question?!? 10 points for best answer!!!?
There have been several small transformers. Soundwave had Lazerbeak, Rumble,and Ravage in the anime. There was also the autobot version Blaster who showed up in later seasons. You also might be talking about headmasters, Brainmaster(may have only been shown in Japan), or the minicons from Transformers: Armada. There was also an episode where 3 Autobots shrunk down and entered Megatron in order to retrieve the Heart of Cybertron.
Q:Wire sizes in the interior of transformers?
High-power transformers are often filled with a heat-conducting liquid. PCBs were originally used for this purpose.
Q:Power drawn by a transformer?
Hello Samantha, in case of ideal transformer the power at the out put would be the same as that in the input. To get the power we need voltage and current. Voltage at the out put is 8 V and current is 570 mA. Hence power consumed by the machine is 4.560 W. So the power drawn in case of ideal transformer will be the same as 4.560 W If the efficiency of the transformer is 86.5% (100-13.5) then the input power will be 5.27 W (approx) To get the number of turns in the secondary let us use Ns/Np Vs/Vp Hence Ns 600*8/120 40 turns.
Q:eee pad transformer or ipad 2?
i flow to attempt to make this record as clean as a danger with out growing to be use of too a lot words: reward of the iPad 2: - Intuitively simplistic (too simplistic to a pair peoples style) - Polished - eighty grams lighter (uncertain no remember if honestly anybody notices that :P) - extra helpful app shop (and stable now graphically some extra desirable ideal video games) reward of the Asus transformer: - swifter (not in many circumstances a substantial vast difference) - Flash help - - TIP: *DISABLE* flash each and each time you don't like it on the asus transformer, reason it improves velocity a lot (apple desperate for the guy that he's not allowed to prepare flash, asus/android believes the guy can take care of a few accountability) - not in straight away forward words a intake (examining/gaming) gadget, yet _can_ be used for production besides - extra helpful battery (because of the dock) - extra desirable ideal show - fairly various customization (you would be waiting to as appropriate run laptop OS's on it :D, yet it fairly is in simple terms for nerds) *My suggestion: in case you may carry your breath for some extra desirable months i ought to suggestion you to watch for the Asus Transformer 2, in any distinctive case the iPad 2 and Asus Transformer a million are fairly matched, yet i think of the Asus Transformer ought to nonetheless have the side*
Q:Why the provisions of the maximum temperature of the provisions of the transformer 65 °?
Most big oil temperature increased load, the transformer internal fault, there is lack of oil performance security risks. So we do need to limit oil temperature and protection tripping. Small capacity (630KVA less and outdoor) often do not have the oil temperature protection. I have the original table 800KVA overload (secondary current 1500A), top oil temperature to over 90 degrees ......
Q:Does anyone know what the movie was without a name on the transformer previews?
this is so funny because i was going to ask the same question on here. hahahahaha.
Q:A liter of transformer oil how much jin
According to the density of the transformer oil can know, a liter of transformer oil weight should be 0.895 kg, which is 1.79 kg. Transformer oil: is a kind of oil fractionation products, its main components are alkanes, cycloalkyl saturated hydrocarbons, aromatic unsaturated hydrocarbons and other compounds. Commonly known as Fangpeng oil, light yellow transparent liquid, the relative density of 0.895. Freezing point <-45 ℃.
