Description

The application of 1140MVA/500kV Three-phase integrated transformer can significantly improve the economy of the UHV substation, 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 470-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 1140MVA/500kV Three-phase integrated 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 1140MVA/500kV Three-phase integrated 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:A lot of people have been discussing the new transformers film transformers dark of the moon-but how does transformers dark of the moon compare to transformers the movie 1986?For those who have seen all three of michal bays transformers films- and Transformers the movie 1986-which do prefer the new transformers movies or transformers the movie 1986?and more Important why?: The 1986 version has better acting on the part of the voice actors, more caring tragedy, more likable Transformers, very atmospheric, and one of the most tragic death's in the history of robot-kind. The first Transformers movie was stupid but fun. The acting in it was okay, the story was incompetent in the fact that they did not explain as much as they could have, bitchy lead actors, and a pretty epic final battle scene. The second Transformers movie is god awful. It is racist, the story is copied from the first movie, the acting is horrid, the characters are bloated bitches that yell all the time, a horrid villain(s), an overactively preachy Optimus Prime, a horrid Optimus death by unknown Decepticon, Transformer balls, bad dirty jokes, Shi Labeouf in robot heaven, Shi Labeouf having a near seizure, Shi Labeouf's mom gets high, and one of the longest unneeded battle scenes in movie history. The third Transformers movie is a step above god awful, racist towards Asians, the story is copied from the first two, the acting is still horrid, Shi Labeouf is self obsessed, Shi Labeouf is mean (he kicked Bumblebee), the Decepticons are cooler but the Autobots are the same, Optimus is still overactively preachy, a blinking camera during the final fight, a horrid Megatron death, a decent twist with Sentinel Prime, bad dirty jokes, Bumblebee getting tickled, a better and prettier actress than Megan Fox, and one of the worst guest appearances in movie history (Leonard Nimoy). C Y I like the old one better. Which do you like better? Also the new Harry Potter has a 100% from all critics.

Q:1000KVA transformer no-load loss is how much?: No-load loss is 1% of the rated capacity of the transformer, then 10KVA per hour. A year down about the loss is 87600KVA.

Q:What is the use of the lower part of the transformer made of rail?: This approach facilitates the handling and installation of the transformer, but due to the large and larger transformers, the use of wheels is already less. Transformer The lower part of the box has two structures: (1) Set the wheels, which requires the installation of the track on the basis of the transformer, and then the wheels fixed on the I-beam track, this way to facilitate the maintenance and installation of the transformer handling, but because of the large and larger transformers, the use of wheels Has been less; (2) set I-beam or channel as a load-bearing beam. This transformer does not need to set the track, on the basis of the transformer relative to the location of the beam weighing embedded flat steel, the transformer in place after the load-bearing beam fixed fixed on the base embedded parts. Need to move the transformer, the chisel spot welding, with the hoist and other machinery will slowly drag the transformer.

Q:630 kilovolt transformer secondary side of the current is how much: Secondary side rated current: I = 630000 ÷ 400 ÷ 1.732 = 909A Primary side rated current: I = 630000 ÷ 10000 ÷ 1.732 = 36.37A Maximum output power P = 630 * 0.95 = 599KW (COS ? by 0.95) The maximum output power P = 630 * 0.9 = 567KW (COS ? by 0.9) 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.). The circuit symbol is commonly used as the beginning of the number.

Q:Hi, there is a utility pole in my lot and there is also a cylindrical shaped transformer hanging off of it. I did some research on it and it is used to step down the voltage from 7000 volts to 120 volts. Does the EMF (electromagnetic field) it generates pose any health threat to the household? Thanks-jj: This Site Might Help You. RE: is pole mounted transformer emf harmful? Hi, there is a utility pole in my lot and there is also a cylindrical shaped transformer hanging off of it. I did some research on it and it is used to step down the voltage from 7000 volts to 120 volts. Does the EMF (electromagnetic field) it generates pose any health threat to the household?

Q:I need to know the details of TRANSFORMER OUTEGE, if possible an equations related ,or any sources for getting idea on this .Pls help.THank u.: Means that someones going without any electicity tonight. A Transformer changes voltage. As in, The Thermostat in most homes workes off 24 volts. A Transformer will take 120 volts and drop it down to 24.

Q:I know that in a step-down transformer if I have 10 turns on the primary coil and 5 turns on the secondary coil that the voltage gets reduced by half and the current gets doubled, but is there any other significance?: Often wondered this myself. There must be a reason why you get transformers with 1000 turns on the primary, and 500 turns on the secondary. If there wasn't a good reason why would manufactures bother putting more than 2 turns on the primary and a single turn on the secondary? The ratio remains the same! Think it could be something to do with the impedance the transformer offers to the input, and output circuits. impedance is kind the AC equivalent of resistance. If it's high then there'll be a fair impedance(resistance to the instantaneous flow of current for a given instantaneous voltage. More turnslonger wirehigher impedance? Matching of impedance between circuits can be important to ensure maximum efficiency/preventing echos etc.

Q:If on the secondary coil we tapped the center to ground, why is it that the top to middle is opposite in polarity when compared to the middle to bottom of the inductor? Also does this only happen if their is a change in current and not constant current going through the transformer?: the first question think of it as a single coil, 24 V transformer when you measure from bottom wire to the top wire you will measure 24V if you measure from bottom to center it will be 12 V the same from the center to the top maybe it is easier to understand if it were 2 batteries in series images.google.ca/images?hlfrsou at the moment in time that the top is +12, the bottom is -12 therefore giving the 24V this is always like that regardless of the nature of the load Anita

Q:I need a flyback transformer for some plasmatastic experiments. I know a place where someone dumped a bunch of broken TVs and computer monitors. Where should I be looking for a flyback transformer in this stuff and what can it look like?thanks: The frequency of an ac power supply is only 60 hz. That's way too low for a flyback. The resistance of a transformer depends on the frequency. At 60Hz a flyback transformer acts like a short circuit. It would draw a lot of power, might damage the power supply and nearly nothing would come out the other side of the transformer.

Q:Hello everyoneMy last question may be a little misleading and I couldn't respond to my own question so please forgive me when I rephrase it again.I have a 65w stepdown Input230/240 AC, Out: 115V AC. 65VA transformer and I wanted to know if I should be concerned about how much electricity the transformer draws just by the fact that it is plugged into the wall socket even when the hardware connected to it is not on.I don't need an exact figure. Just a layman's terms as what your typical transformer would draw. An absolute average idea of the average transformer.If I turn the transformer off, all my appliances will need to be reset when I turn the transformer back on again.So does an average one consume as much as a light bulb, or say something much more. like a computer etc.I just need a general idea. Thank you.: As jack w correctly says, transformers are among the most efficient machines around; more than 99% efficient. The slight warmth you feel when you touch a transformer is the energy wasted as heat. So a 65 watt transformer wastes less than a watt of power when it isn't putting out any power. At the price we pay for power here in NZ, that's not much more than 1/100 of a cent an hour. So the money you waste per day by leaving it plugged in wouldn't even buy you a dog turd.
