Description

The application of the 430MVA/242kV main 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 430MVA/242kV main transformer 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 the 430MVA/242kV main 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: How to connect in parallel the following transformers:a) Dy1 Dy11b) Dd0 Dd6: I don't recognize your transformer designations in a) and b). Perhaps they are industrial transformers that I am not familiar with. My background is electronics, not power distribution. That being said, I'm not sure why you would want to connect transformers in parallel. Possibly to handle a load that exceeds the capacity of one transformer. If this is the reason, it would be better to split the load between two transformers if at all possible. If it is a single load that can't be split, the turns ratios for the two transformers would have to be exactly the same. For that matter, the transformers should be exactly alike, to make sure that they carry the load equally. (A higher source impedance in one transformer would cause the other transformer to carry more than its share of current.) Then it is very simple: connect like terminals together, taking special care to line up the phases. If for some reason you are unable to identify the phase (commonly marked with a dot next to the winding on a schematic diagram), do the following: 1. Connect the primary windings together, wire 1 to wire 1, wire 2 to wire 2. 2. Connect one wire in the secondary of one transformer to a wire in the secondary of the other transformer. 3. Carefully apply power. 4. Measure the voltage between the two loose secondary wires. It should be zero. If not, change one of the wires in step 2 above.

Q: I was wanting to buy my little brother a transformer toy, but not one of these cheap ones you buy today, but one you actual transform by yourself like when I was younger. So whats a good website where I can find some for him and me to play with, and I don't really want to spend to much on them, just enough.: Amazon

Q: What is the M of the transformer capacity MVA?: M on behalf of trillion. MVA represents the capacity of the transformer, read as: trillion volt. The conversion unit is 1MVA = 1000KVA = 1000000VA. 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.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q: I got stuck in a problem while solving the previous exam question for my courseTwo transformers with unequal turn ratio and unequal ratings are connected in parallel and have the same secondary voltage. How will the load be distributed between them? Hence find the circulating current.I know how to find the circulating current when the secondary voltages are different. But how can there be a circulating current if the secondary voltage is same?And I know about the load distribution being inversely proportional to the line impedance of the transformers, but what will be the change taking circulating current into account?: To me it is a typical circuit analysis problem. From an application engineers point of view , to analyse the problem, the following needs to be checked first 1) Open circuit Voltage of both the TRXs 2) Internal impedences of TRXs 3) Total Load to be catered to ( converted to in terms of Z) 4) Ratings of the TRXs ( Rather allowable current that can be drawn from each TRXs) Having known first three quantities , we can make the parallel circuts and calculate the current in each branch ( through TRX1, TRX2, and the load) andtheir directions The fourth quantity will tell us if loading is within limit or not.

Q: Does anyone know where I can buy Transformers in Bluray? I have looked for it everywhere and can't find it and I need it for a Christmas gift.Thanks!: im not sure but i believe dreamworks to be one of the companies not supporting blu ray

Q: I have a transformer with serial number T.K.K EHT 66001 S-2. I confused with input (primary) wires. it has 5 wires (white red brown yellow and blue). which wires is used for 220 vac?? please help.: It looks like you MAY have an auto-transformer, ie only one winding. Off hand, I would say the white is supply live and blue the common return. If you measure the DC resistance of White to all the others and record reading. Then red to all others as above and same with brown, yellow and blue. The pair with highest reading Should be the primary, it doesn't really matter which is live or neutral, as long as you take the return of the secondary to the neutral. The other 3 wires will give you 3 different voltages with respect to neutral, however the EHT in the serial No. May indicate Extra High Voltage, which is not 220v. by any stretch of the imagination. Is there no information whatsoever on the transformer itself? Clear as MUD I know, but I'm not good at explaining things. Your meter should be at the lowest range, as this is DC resistance you are measuring, not AC.

Q: does anywon kno if michael bay will bring back any robots that died from his previous movies? like jazz or bonecrusher or brawl anything like that. and i know that their making transformers 3 but does anyone know whats its going to be called or what are some new transformers? thank u for all ur answers. exept the crappy wons. il just delet thos. even tho u cant. ???: Okay let me start off by saying i'm not a nerd i just love transformers. lol. But from what I've heard the title is Transformers: Ascendents of Cybertron. The main villian is Shockwave. Megatron, Starscream and Soundwave are the only three that have been confirmed to be in the third one as of now. For the autobots Optimus, Bumblebee, Ironhide, Ratchet, Sideswipe, and the twins who Bay said weren't coming back are coming back. New characters for autobots include a robot named Silverbolt a red ferrari, a purple car, a blue car, and an autobot scientist. Also there introducing a new team of robots that will work with the autobots called the Wreckers, three nascars. There will also be two robot assasins ( decepticons ). And as for any returning unknown but i can tell you this they have comics that take place in between the movies and there coming out with a comic series called Transformers: Nefari or something like that which takes place after the second film and somehow Ravage the dog like decepticon who was killed by Bumblebee somehow comes back to life and Alice that robot chick from college somehow comes back and was captured by sideswipe after stealing an RV and was taking to NEST for tests. Oh and one more thing. The film is supposed to start of during the days where John F. Kennedy was president and something with a decepticon on the moon happens. But the film supposely says that the decepticons had something to do with the cold war and World War II. Hoped this helps

Q: 110kv level, the capacity of about 43MVA transformer models and detailed parameters: Now 110kV transformer capacity is generally 50MVA. Models are generally SZ9, SZ10.

Q: KW how to know how much transformer?: Transformer is rated by the kilovolt, is the apparent power, know the kilowatts, with the kilowatts divided by 0.8 is KVA, should stay a certain margin, preferably 20% of the amount. for your reference.

Q: I would like to attend a Transformers 2 Premiere where the cast will be present. Is that possible? Are these shows usually closed/private? Do I have to be in Hollywood? What should I do?: I think so.
