Description

The application of the 68MVA/500kV standby transformer power plant, 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 68MVA/500kV standby transformer power plant. 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 68MVA/500kV standby 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 UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.

Q: What is the transformer through the full and half through the problem, the definition of a little more, the best reference, or sent to my literature.: (4) Splitting coefficient: The ratio of split impedance to crossing impedance. The description of the method of the standard method shows that the commutation reactance measurement of the rectifier transformer is similar to that of the transformer short-circuit impedance measurement. The difference is that the measurement of the short-circuit impedance is usually made by connecting the low-voltage side of the transformer and the high-voltage side to the rated current, And the commutation reactance measurement of the rectifier transformer is to short-circuit the high-voltage side and to measure the voltage between the terminals at the low-voltage side with the rated single-phase current. It can be seen that the commutation reactance of the split transformer is a half-crossing impedance.

Q: During the trailers before the movie transformers, there was a trailer for a movie that looked like it was done by an amateur video.It didnt have a name but it had the statue of liberty flying through the streets.Anybody know the movie or wat the movie is about?: From today's Variety: Paramount and J.J. Abrams are playing coy about a mystery-shrouded trailer running before Transformers'' in theaters around the country. The trailer is apparently for a Bad Robot monster movie code-named Cloverfield,'' which Paramount will bow Jan. 18. Shot Blair Witch''-style with handheld cameras, it shows revelers sounding off at a Gotham birthday party until mayhem strikes. The trailer carries no title, but at the end, it flashes From producer J.J. Abrams,'' then the release date and a quickie credit block. Pic is being directed by Felicity'' co-creator Matt Reeves and written by Lost'' and Alias'' cohort Drew Goddard. Within days of the Transformers'' opening Monday, clips of the trailer had been removed from YouTube at Par's request. Yet a Bad Robot staffer close to Abrams feigned ignorance about the trailer - which bears the company's logo - Thursday afternoon. This isn't the first time Abrams has been involved in mysterious schemes to promote his projects. Last year, Hyperion published a tie-in tome to Lost,'' the series he co-created, supposedly penned by a character on the plane that set the skein into motion. And the series aired mock ads for the Hanso Foundation that led viewers to various websites promoting a game tied to the program (Variety, May 22-28, 2006).

Q: Calling all fans of Transformers! I am looking for anyone to tell me if Transformers Animated is coming back for a third season on Cartoon Network. The reason why I am asking this question is because I recently bought the second season of the show and noticed that they have a lot of information on new characters as a special feature and I am wondering if those characters will be in the third season of the show.: That would suck sooooo bad if it is cancelled. All that build up in the first season with super villains and no Megatron and like, 3 Decepticons till the end of season 2 for what! To take it all away just as its getting good and finally setting up a full on Autobot Decepticon war There better be a season 4 or this series will go in the forgotten bin with Robots in Disguise as another series that took forever to set just for 1 big battle then that's the end. But if it is the end then that will teach the writers for holding out on what fans really want. I can not sit through season 1 or 2 again, except the season 2 finale.

Q: A buddy of mine has some new old stock DVDs at his store. He has the G1 Transformers Seasons 1-4 boxsets by Rhino. They are in mint condition and factory sealed. He said if I want them he will throw in the G1 Transformers movie(Rhino version) and the 20th anniversary version both factory sealed. He will sell me this DVD collection for $300.00Is it worth it? Are these DVDs worth that much money? I would like to own the G1 series I just want to know if this is a fair price.: Even though the original Transformers series is brilliant in it's animation, voice acting, and overall robot-lazer battle-isciousness; it most definitely is not worth that much money. Even if the special features are epic. However, many websites have links to the episodes online, so you can watch the OG Transformers over the inter-tron. Or the gumple-tron, which is an entirely unexplored medium of wireless communication yet unknown to humans.

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: Whatever okorder

Q: hi can anyone tell me when installing/replacing a door bell transformer when switching off power supply at main source will that make it safe to work with the connections, it keeps telling us to turn fuses off well it dont have fuses its a circuit breaker. so do we turn circuit breaker off asweel as main supply into house. may be a silly question to ask but dont wnat any trips to A nad E lol thanks guys xxx: Although, I have not tested a unit like you mention, I would get the 1.5a unit because that is the maximum it puts out in amperage. If your bell uses less its OK

Q: I want to make a simple flyback transformer driver. I have a flyback transformer of samsung CRT monitor. Can anyone give me a complete design of flyback transformer's pin. What are the required components. Please give answer in detail.: submit a schematic and a few concepts on the transformer. Circuits with transformers continuously have some inductive power that could desire to be dissipated whilst the transistor(s) turn off. this could reason extreme voltage spikes which could unquestionably injury a transistor (whether the case isn't warm). you may desire to guard in comparison. A 2N3055 is an quite sluggish gadget and not very proper for top velocity switching.

Q: I use a 1000 watt transformer for my tv, dvd player, cd player, game cube and nintendo (only 2 can be plugged in at a time or it is a fire hazard). The transformer is very strong and flips the circuit breaker if anything else in the house is plugged in and I try to plug that in. I'd rather not have to unplug everything to plug it in but I am worried I am wasting electricity if I keep it plugged in. So my question is does transformers use energy if they are plugged in and the appliances plugged into it aren't turned on? Also, do you think I can use a smaller transformer for those items listed above if it does use energy? The boxes that I buy them in don't say, they just say what watt they are.I've tried to look it up but I can't understand any of it so thank you in advance for helping me.: Yes they use electricity

Q: From the following transformer, how would I calculate:a) the equivalent impedance on the low-voltage sideb) Converting the impedance found in (a) to it's per-unit quantities: a) the turns ratio of the transformer is 20 to1 so to refer an HV side impedance to the LV side you divide it by the square of the turns ratio which in this case is 400 which gives: 0.001+j0.00025 ohms. b) There's a certain amount of freedom in doing this for you may define the per-unit impedance base however you want. It is however rather usual to define it as VA / I^2. Here I 5000/2400 2.083 amps So base impedance HV side 5000/2.83? 624 ohms making the given impedance (0.4+j0.1)/624 p.u. This p.u. value should be the same on either side of the transformer. Nice to see you around again but do I notice you haven't improved at saying please when you want someone to do something for you for nothing. If you can't learn that there's not much use in learning all these technical skills. You're going to remain a clumsy oaf!
