Description

The application of the 360MVA/242kV three phase water cooling main transformer for hydro power station.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 360MVA/242kV three phase water cooling main transformer for hydro power station. 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 the360MVA/242kV three phase water cooling main transformer for hydro power station, 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: Does anyone know the storyline to Transformers 2? A release date would also be great.: Sam Witwicky discovers something about the origins of the Transformers and their history on Earth. The evil Decepticons need to capture him for information. The climactic battle takes place at the Giza pyramid complex, where a temple is located within. Lorenzo di Bonaventura explained the film will show the Transformers who visited Egypt before the pyramids were built, and all our heroes end up here because of the Decepticons' masterplan. Furthermore, Egyptian hieroglyphs resembling helicopters and other present day vehicles in real life will be explained in the film as being depictions of those ancient Cybertronians who visited Earth. The release is set to be June 26, 2009

Q: High power transformers are very common, for obvious reasons. Much unlike homemade transformers that I've ever built, only out of tiny enameled #26 wire, that wouldn't power anything practical.I've tried using wire as large as #6 wire to wrap a homemade transformer, as what would be needed to connect externally to 10 kVA transformers, but that simply isn't practical. The wire is simply too stiff to wrap it in tight windings.Consider the example of a 225 kVA three phase transformer, that carries about 300 Amps of current on each of its secondaries that are 277 Volts. Externally, I'd need to connect with 400 kcmil wire, that is almost an inch in total diameter. What exactly do they do in order to build transformers at this high power?Do they parallel a whole bunch of tiny windings?Do they use a cooling fluid, so that tiny wire can have a much greater ampacity?Or do they also use big wire, but the way it is constructed somehow relieves the strain resulting from wrapping it? Heat treating the metal, perhaps.: Wire must be chosen to that the current density does not cause them to overheat.

Q: Want to use in the air compressor, I do not know it?: Can not! Two kinds of oil indicators out of the thousands of miles out! According to you say with the line also do more money to prepare for the machine! Oh! Looking for compressor oil, general 13 # compressor oil and 19 # Compressor oil! 13 with dilute words on the 19 # must be no problem!

Q: I have a 150 watt bank of photovoltaic cells that run at 12 volts (PWM mode non-mppt charge controller). My question is, by substituting a dc transformer (one that boosts current and steps down to 12v) for a current boosting mppt, can I run the solar panels at their full rating even though they are connected to a 12 volt battery bank? The 12v batteries, when directly connected to the solar panels, drop the output because the panels output their full current at a higher voltage.I am also wanting to apply this logic to a wind turbine that outputs a maximum of 30 volts dc. I am thinking that if the switching transformer works for the solar panels, it would also work to step down the wind turbine's harsh dc voltage to a current boosted 12v state. Would this theoretically work?: Transformers don't work on DC. You need a DC to DC converter.

Q: What are the technical parameters of the transformer?: I, temperature rise and cooling: transformer winding or the upper oil temperature and the temperature difference between the ambient temperature of the transformer, known as the winding or the upper oil temperature rise. Oil-immersed transformer winding temperature rise limit of 65K, oil surface temperature rise 55K. There are a variety of cooling methods: oil from the cold, forced air-cooled, water-cooled, tube, chip and so on. J, Insulation level: Insulation class standard. Insulation level of the method for the following example: high voltage rated voltage of 35kV level, low voltage rated voltage of 10kV level transformer insulation level expressed as LI200AC85 / LI75AC35, which LI200 said the transformer high voltage lightning impulse withstand voltage of 200kV, power frequency withstand voltage For the 85kV, low voltage lightning impulse withstand voltage of 75kV, power frequency withstand voltage of 35kV. Oaks High Technology Co., Ltd. The current oil-immersed transformer product insulation level LI75AC35, said the transformer high voltage lightning impulse withstand voltage of 75kV, power frequency Withstand voltage of 35kV, because the low pressure is 400V, can not be considered. K, the connection group label: According to the transformer one. Secondary winding phase relationship, the transformer winding connected into a variety of different combinations, known as the winding group. In order to distinguish between different groups, often using the clock representation, that is, the high voltage side of the voltage phase of the clock as a long needle, fixed on 12, low voltage side of the phase voltage as the clock short needle, (A) is a (triangular) joint, and the secondary winding is a (star) junction with a center point, and the group number is (11).

Q: What is the reactive power compensation of the transformer?: The use of capacitors to compensate for reactive power, improve the transformer's active power output capability.

Q: I'm a student in high school in a basic physics class. My teacher assigned a report and presentation about electric transformers(because its not in our textbooks), but the information i get from websites is too complicated for me to understand.(ie wikipedia) Is there a website where i can get thorough info that is easy to understand?: $20 at most big electronics retailers, within 500 watts larger transformers can be up to $100 to 2000 watts.

Q: Can anyone explain what each wire does in this spicific microwave transformer: I believe the two tabs on the lower part of the transformer on your first photo, is where the mains voltage is applied ( 120 or 240 volts AC depending on country used ). If you use an ohmmeter and measure for resistance, there should be a low resistance between the two tabs, and infinite resistance to the other wires and infinite resistance to the frame of the transformer. On the second photo: The two wires will have a high voltage AC output on them when measured from either wire to the frame of the transformer. One end of the high voltage winding is attached to the frame of the transformer as a ground return. You can see the attachment near the top of the transformer. There is also a voltage superimposed between the two wires on the second photo. This is used to heat the filament of the magnetron tube. If you measure the resistance between the two wires you should get a very low resistance. If you measure from one wire and the frame of the transformer, you should get a higher (but not infinite) resistance.

Q: How many different types of transformers are there if anyone can remember from the cartoons?: There's quite a lot

Q: I'm a good Transformers fan, but i've only really watched the more recent shows like armada, energon, etc. so i'm confused with some things in the new movie:1. Is Jetfire really supposed to be that old?2. Jetfire mentioned the Optimus must be the last decendent of the Primes? is Omega Prime one or no?3. When the Fallen appeared in the comic where he first showed up, did he have the same power over Megatron4. Did anyone else notice that Ratchet just showed up during the forest battle scene?5. Did Megatron transform into both the cybertronian tank and plane in the movie?6. Anyone else find the Twins insainly rascist?7. Is Wheelie supposed to be a small toy in the universe?8. Is the human changing robot really in the series or just the movie?9. Can Constructicons really morph with each other to make a giant?10. Is Starscream the one that eventually switches to the Autobots?11. Does the Decepticon attaching itself to the sattlelite have a name?Thank You for clearing things up: 1. No Jetfire isn't that old. although his age might be a little higher than others. 2. Omega Prime is a fusion of Optimus Prime and Ultra Magnus. So technically the answer is yes and no because it's actually Optimus Prime fused with another transformer. 6. Not really. It was just extremely stereotypical and a little annoying. But if you think that all stereotypical representations in movies are racist, then you'll have a problem watching any movie. Take asian stereotypes for example. 8. Pretenders (what the human changing robot is called) were first conceived in 1988, I think by Marvel Comics not sure about that. And yes it was in the Marvel Comics production of Transformers cartoons. 9. Yes, in the cartoon series they were able to merge into a larger Transformer called Devastator. 10. No, Starscream always tried to take control of the Decepticons behind Megatron's back or when Megatron is injured (eventually he is killed by Megatron-turned Galvatron). Jetfire is the Transformer that switched sides from the Decepticons to the Autobots. 11. The Decepticon's name is Soundwave.
