Description

The application of the 380MVA/525kV single-phase double winding generator transformer Power Plant.can significantly improve the economy of the OLTC substation, and matches well with the transmission capacity of OLTC 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 the 380MVA/525kV single-phase double winding generator transformer Power Plant. In order to make the products applicable to any OLTC substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity OLTC 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 OLTC 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 OLTCtransformer 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 OLTC Transformer’s right at the first time once again filled the gap in the field of OLTC transformer research after Chinese transformer industry overcame the difficulty of integral transport of the 380MVA/525kV single-phase double winding generator 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q: I think it will. Michael Bay who doing the movie has a history of messing up classics. Godzilla is my prime example. So, what do you think? Transformers the movie: Good or Bad?: Yes, it will suck. As a scientists and former electrical engineer / super evil nerd, I'd have to say from the trailers this whole movie looks bad. I've been looking at the current graphics (i'm also into 3D design with BRL-CAD and Blender) and I would have to say the autobots and deceptacons were made all wrong. Also, something that has been bugging me about the trailers, is that too many humans are appearing in the film. The humans keep talking. They blab. The movie is called Transformers. It's about transformers. It's not like Terminator where the human race is greatly involved. No, in Transformers, a lot of the stuff revolved around Cybertron. A good amount of the time, humans talked little while the robots talked lots. I'd like to say I've watch a lot of Transformer's episodes through the time I've been alive. And as I looked at the trailers, I didn't really see any of the Transformers talk. I saw mostly people talking and yammering in awe and amazement at the fact that transformers are alive. Now, some people are saying the transformers are voiced by some people, and Optimus is going to be voiced by the a former voice person. However, I just don't think it's going to be as great as the cartoons one bit. I don't think the whole urban sprawl bit was a good design. I think the robots were made with too many shades of dark. I mean, look at megatron's design; it's all bad. Also, as I watched one of the actors on Jay Leno, I saw him talking about the movie. He only cited that Transformers is from the 80s. He didn't talk about Transformers in the 90s, 2000s, and other versions of the Transformers. In my opinion, nobody knew what they were doing when they were making this movie.

Q: What is the power transformer, what is the rectifier transformer: Rectifier transformer is isolated transformer, is often used in the power distribution cabinet to do the power.

Q: What is the M of the transformer capacity MVA?: MVA with a table of his capacity, read: trillion volts in which M with a sign The conversion unit is 1MVA = 1000KVA = 1000000VA

Q: Transformer oil filter method: 2, vacuum oil filter to ensure that there is a certain number of power, taking into account the size of your transformer, oil pillow position level, the oil filter is too small may not go oil cycle 3, the oil circulation from the oil pillow on the opening of the valve, where the best open after the bandaged, to prevent other debris in the filter oil fall into the transformer oil pillow. 4, filter oil after a certain time, take oil samples. Qualified to stop the oil filter, add the oil inside the oil can be closed after the oil pillow upper check valve. The transformer can be powered by one night after standing.

Q: does anyone know how big the transformers are in the movie or have an online reference?: lol to tell you the truth, I've been to the L.A. Transformer's movie premiere, I've seen a life-size BumbleBee model with my own eyes and it's about 2 stories tall (I also took some pictures but not clear though)? Optimus Prime, about 3~4stories tall? And if you use search engines, you might find some funny insider stuffs from fansites, have fun!

Q: I have been reading wikipedia and have gotten confused.Va.Number of Coils on side a---- ._________________Vb.Number of Coils on side bwikipedia mentioned how power companys use transformers for converting to high voltage power li nes then use transformers to bring the voltage back down.Focusing on the transformer that jacks the voltage upwirea-[side a-Transformerxyz- side b]-wirebso assum wireb is the high voltage power line.--Which side of transformerxyz would have more coils ? My guess is that side b has more coils then side a--Is it safe to say that the wattage of side a is equal to side b?--they said something about magnetic flux, does this just mean that the material connecting side a to side b has to be magnetic?--they said that the insulation wears down in transformers over time due to heat. what is causing this heat?--they said something about leakage and spacing of coils, what does this mean?tyVVVVVVVm: The previous answer is correct, but the following may be helpful. A transformer works by the linking of changing magnetic flux produced by one loop or coil (the primary winding) with another coil (the secondary). That is why transformers only work with alternating current or pulses. Magnetic iron has the ability to increase the magnetic flux produced by a coil. This is called its magnetic permeability and can increase the flux produced by factors of several thousand or more. Leakage flux in a real transformer is the amount of flux produced by the primary that does not link the secondary. This flux is wasted and reduces the efficiency of the transformer. Heating of the wire insulaltion not only comes from the resistive heat of the windings, but also the heat produced in the magnetic material (core) of the transformer. These losses are called eddy current and hysteresis losses and can be quite substantial. The reason that cores of transformers are laminated (stacked thin sheets of magnetic iron) is to reduce the eddy current losses.

Q: S11-1250kVA transformer oil capacity how much: The total amount of oil in the transformer: the amount of oil supplied by the transformer body transport + (the amount of oil required to be added to the main body) + (the amount of oil added to the oil conservator) + (transformer accessories - such as the amount of oil required for the radiator )Wait. The amount of oil added in parentheses is the transformer factory, and the oil drum is installed and delivered to the customer. So customers receive the transformer, the transformer should be the total amount of oil is acceptable enough

Q: Can somebody please help me understand this problem and help me do it? I'm having a hard time with it and help would be greatly appreciated.The following test data were obtained from short-circuit and open-circuit tests of a 50-kVA, 2400-600 V, 60Hz transformer.Voc600V Vsc76.4 VIoc3.34 A Isc 20.8 APoc 484 W Psc 754 WDetermine:A) the equivalent high-side parameters;B) RegulationC)efficiency at rated load and .92 power-factor for lagging.: read material regarding transformers Not just once but say 5 times, till you understand what is said. the transformer has copper loss due resistance of primary and secondary. It has additionally iron loss. The equivalent circuit is a sort of representation that brings in these losses. generally you can apply a low voltage to primary till shorted secondary has a current equal to less than rated current. These measurement details are given. Similarly open circuit measurement details are available. With understanding of how the rest can be calculated using worked examples in texts, you can solve it yourself. attempt this See Lee's book on transformers or schaums series on electrical engg.

Q: I have a standard transformer with 7 wires:2 black2 red2 yellow1 red/yellow stripedWhat connections do these wires correspond to?That is, which should connect internally to the primary coil, the secondary coil, and coil-taps (based on the number of wires, I assume that the secondary coil is tapped).I must determine this in order to connect the wires (externally) appropriately.Any help is greatly appreciated!: Raptor gave good info. I would add just a few points: 1. The high voltage winding usually has the smaller gauge wire. 2. The high voltage (primary) winding also usually has a higher DC resistance and fundamental frequency impedance than the secondary. 3. Be sure to scrape the insulation off the wires before checking the resistance. Many years ago, an idiot I was working with didn't recognize that the wires had enamel insulation on them, and connected the transformer backwards. It was a 480 V / 1 V (or so) instrument transformer. We lost a lot of good equipment and nearly lost people because of that screwup. The recorder saw 2 kV before it died.

Q: I really want the transformer but if i buy it i have to wait for shipping. But on the other hand if i buy either one i have to wait 2 weeks for the other.: killzone 2!!! Is the best FPS game rigth now
