Description

The application of the 40MVA/20kV split auxiliary 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 40MVA/20kV split auxiliary 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 40MVA/20kV split auxiliary 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: Transformer ratio and transformer ratio: Transformer ratio K and transformer voltage on both sides U1 U2 winding turns N1 N2 current I1 Ⅰ2 have a relationship! In the ideal case, the ratio K = U1 / U2 = N1 / N2 = I2 / I1

Q: I love the Transformers movies and games to death, but I've never ever been able to like the cartoons.I know they were somewhat popular, especially as the first Transformers game was a huge successplease add why you like/dislike it.thanks in advance: I hated the old transformers cartoon movie with a passion. Mainly cause my ex used to watch it over and over and over again, and Cry at the optimus part every freakin time. By the time we broke up, I wanted all transformers things to die. I'm recovering slowly.

Q: A single phase transformer operates from a 230V supply. The primary and secondary resistances are 0.03 Ω and 1.12Ω respectively while the corresponding leakage reactances are 0.1Ω and 6.4Ω; the magnetising branch can be neglected. The secondary winding has four times as many turns as the primary. Calculate :i) The equivalent impedance referred to the primary circuitii) The secondary terminal voltage when the load has a resistance of 200Ω and an inductive reactance of 100Ω.iii) The secondary terminal voltage when the load has a resistance of 200Ω and a capacitive reactance of 100Ω.Can someone show me how to tackle this question please?: i) the secondary transformer impedance is 1.12 + j6.4Ω. Since Ns/Np 4, this impedance reflected to the input is (1.12 +j6.4Ω)/(Np/Ns)? 007 + j0.4Ω ii) Reflect the primary transformer voltage and impedance to the secondary side. 230(Ns/Np) (1.12Ω + j6.4Ω + (Ns/Np)?(0.03Ω + j0.1Ω ) +200Ω + j100Ω )I 920 (1.6 +200 + j8 +j100)I (201.6 + j108)I |Z| 228.7Ω √(201.6? + 108?) at angle of inverse tan (108/201.6) 28.18° I 4.02 amps at -28.18° 3.54 - j1.90 amps The terminal voltage is 920 - (1.6Ω +j8Ω)(3.54 - j1.90 amps) iii) solve 920 (1.6Ω +200Ω + j8Ω - j100Ω)I (201.6Ω - j92Ω)I The terminal voltage is 920 - (1.6Ω + j8Ω)I

Q: I was wondering what year is transformer 2 cuz the first 1 was freakin awesome!!!!!!!!! and i wanted to see a second 1 but dont know which year and i heard there was going to be another one transformers 2.: they are still making the sequel :) but I love the first one too!!! :)

Q: How many transformers games are for the xbox360 and what ones are based on the old tv show? And what ones are based on the movies? Please give complete names and in order! Thank you (:: Hmm 'Play O' took my answer :(

Q: Transformer Uk = 4.5% What does it mean?: Transformer short-circuit impedance, that is, his own impedance. The impedance is large, the transformer needs to resist the short circuit current multiplier is small, relatively speaking, anti-short circuit capability, but the transformer's external characteristics (volt-ampere characteristics) soft (with the transformer output current increases, the output voltage - transformer Voltage drop is very powerful). On the contrary, short-circuit impedance is small, the transformer needs to resist the short-circuit current multiplier, requiring a strong anti-short circuit transformer capacity. Of course, the external characteristics of the transformer better. Another short-circuit impedance will also affect the transformer manufacturing costs. He is not the bigger the better, nor the smaller the better. To be considered, so there are strict rules in the national standard.

Q: I am building a simple circuit and was wondering what is the difference between a coil and a transformer? Also, in my circuit I have a generator. My generator is made up of a coil and magnets. I would like to know do the amount of turns my coil is determine the power of the generator? When I select the gage wire I am going to use we that determine the amount of volts and current I can gain from my generator?: A transformer is nothing but a magnetic core on which two isolated coils are wound. Power of generator depends on many factors 1. Size and strength of magnet 2. Size and magnetic properties of iron parts 3. Rotating coils, speed, diameter, length. Gage wire is chosen based on volt / ampere considerations, not the other way.(gage does not decide voltage and ampere of the generator)

Q: A topic that: a three-phase transformer wiring is YN, Y, a0, d11, all mean what? Three-phase transformer how four ways to connect it?: If the three-phase transformer has four windings can not have four kinds of wiring way?

Q: I hate feeling the need to justify myself, but I've seen a lot of answers telling askers to do their own homework. I'm trying to do so, but can't find any equations in the book relating power to voltage as well as turn number. Is it PviN? I've just seen Pvi, but that wouldn't apply to multiple loops. This is for ideal transformers by the way, so power for the secondary and primary coils is the same right? But are their vi's equal, or their viN's?The primary coil of a transformer has 200 turns and the secondary coil has 800 turns. The power supplied to the primary coil is 400 watts. What is the power generated in the secondary coil if it is terminated by a 20-ohm resistor?: The turns ratio is 4:1 of the primary. The power supplied to the primary is 400W. So regardless of anything else, in a ideal transformer, 400W is available on the secondary. But voltage will be 4x higher, current 4x smaller, than the voltage and current in the primary. Disregarding all that, if there is 400W of power flowing in the primary, then 400W will be being dissipated in the 20 ohm resistor. Watts in watts out, but secondary load (resistance) controls the wattage. There is no way to tell the output voltage and current, without knowing the input voltage and current. But whatever they are, the product of voltage x current will be 400W, in this instance.
