Description

The application of 240MVA/345kV three-phase OLTC auto-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 240MVA/345kV three-phase OLTC auto-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 240MVA/345kV auto-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:I am build a band pass filter but I am wondering if one of the inductors in my filter can act as a transformer at the same time. I'm assuming not since it would be sending all its magnetic energy into the secondary rather than back into the primary. Can someone confirm this for me please? Also, if it DOESN'T act as an inductor than would it be okay to put it in parallel into my filter? Or do I put it in series? Where do I put it lol?Thanks: The primary of a transformer has a fairly large inductance called the magnetizing inductance. This inductance could be used as a filter, but it is not a good idea. First of all, it will not support any appreciable DC current, because it will saturate. In addition it is usually very nonlinear. If you want to filter the input voltage use a separate filter.

Q:I am seeing the TRANSFORMERS series now for the 1st time, unfortunately I do not have all the EPISODES. Megatron turns to Galvatron, What Happens to OPTIMUS PRIME?? Does he change too?? Who is GALAXY CONVOY???What is the Final Episode of the Series, Who will be Alive at the End and Who is Defeated?? Please explain me in Detail,,,In Depth.Thanks in Advance.: wow, I so sorry I tried asking my kids but they don't remember, I do remember that megatron turns into galvatron and yes optimus does change to something, but my son says optimus dies and optimus says before he dies he takes the all spark out of his chest and he says take care of it he hands it to hot rod and then hot rod hands it to the old truck guy the old truck guy give it to RC and RC gives it to a transformer that is red a blue and resembles optimus the optimus turns black. that was part of the movie. the televison series ( I am typing this as they are arguing over what happened ) perhaps the cartoon network website or even wikkipedia could help with recaps type into your web browser, wikkipedia transformers animated, or if you want info about the recent movie shown at the theaters, type in wikkipedia transformer.sorry my boys and I couldn't be of more help, I don't understand why they couldn't remember we used to watched this show together all the time before school.

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:how are opyimy and megatron ( or w/e the f their names are)bros and hoes if they cant have roboet sex!!! if so wheres their mother and is the creator sexist about girls there is no girl robots and for that matter has some1 made a transformers porn yet.: Females - Arcee, Nightbird, etc (and that is just from the 80s) Porn - Yes, see Rule 34

Q:Sichuan transformer manufacturer that a best?: Sichuan Meishan New Transformer Co., Ltd.'s products have the strongest load capacity, up to 200%

Q:I need to find out.I am a huge Transformers fan.: You can't be a real fan if you haven't watched the original animated series. The movies are crap, they just have nice special effects.

Q:500KW load should be installed how much transformer?: Mainly to see what the load, if it is home lighting electricity, according to the 0.9 power factor and 20% of the margin, you need to be equipped with 500 / 0.9 / 0.8 = 694.4, you can take 750 kilovolt capacity can be. (Consider the future expansion of another operator), if it is with the motor and other load-based, due to power factor and start the current reasons, at least 900 kVA more appropriate. If the drive is more than 200 kilowatts, the starting current is very large, you need to put a larger margin or the motor using the buck mode (increase the investment cost).

Q:I can't remember the funny scenes from any the Transformers movies, especially 1 and 2.It's driving me nuts.I saw the third one just last week so I remember a couple of funny scenes, but other than that, no luck.If you can, could you please include a link to a video clip of the scene?Thanks so much! (:: I'll give you scene by scene from each movie that I can recall. I apologize for the lack of videolinks but I'll describe them as best as I can. Transformers: Bobby Bolivia (Bernie Mac) talks about his mom. Oh l love that woman if I had a rock I'd crack you in the head, b***h. Sam gets arrested and interrogated by the cops when Bumblebee runs off to communicate with the rest of the Autobots. What's this new thing they're on? Mojo? Ratchet sniffs the air when introduced to Sam and Mikaela. The boy's phermone levels suggest he wants to mate with the female. Mikaela makes Simmons take off his clothes. He has a Sector Seven t-shirt on underneath. Sam, Mikaela, Maggie, and Glen are flying to Hoover Dam. Rachel: So what did they get you for? Sam: I bought a car, and it turned out to be a giant alien robot. Who knew? Revenge of the Fallen Sam's mom and dad fooling around before their trip in front of Sam. Dad, this is not a rap video. Leo doing his funny dance while Burning Down the House is playing. Anything involving the Twins and Wheelie. Sam's mom. Oh, professor, I'd do anything for an A after eating a hash brownie (LOL! Funniest part of the movie). Simmons strips off his pants and shows he's wearing a Sector Seven cup underneath. Lennox tricks Director Galloway into parachuting off the airplane.

Q:I have a 34kv/380/500KVA transformer and it loads a pump of 450HP/2200V. Starting current reaches up to 1700 amps for around 3-4 seconds using a soft starter. The rated capacity of the transformer is 700amps and the pump running current is 689 amps.Any calculations to prove that the transformer is enough to provide the application would be a help.thanks.: Damn, had to read the question before I realized it has NOTHING to do with Optimus Prime or Megatron. (*laughing*)

Q:What is the main purpose of the transformer?: If the secondary connected to the load, the secondary coil to generate current I2, and thus produce magnetic flux ф2, ф2 and ф1 opposite the direction, played a mutual offset effect, so that the total magnetic flux in the core has been reduced, so that the primary Self-induced voltage E1 reduced, the result is I1 increase, showing the primary current and secondary load are closely related. When the secondary load current increases when I1 increases, ф1 also increases, and ф1 increase part of the part is just to be replaced by ф2 that part of the magnetic flux to keep the total magnetic flux in the core unchanged. If you do not consider the loss of the transformer, you can think of an ideal transformer secondary load power consumption is the primary power from the power supply. The transformer can change the secondary voltage by changing the number of turns of the secondary coil as needed, but can not change the power that allows the load to be consumed.
