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 have a friend who lives in a place that she converted to a liveable space at a movie studio complex; however, the space is right above the transformer used by the studios for power. At night we can sometimes hear some buzzing sounds. How dangerous is this? We've heard things like it causes cancer in the long run, and that it is simply not safe. Does she have to worry about it? She's been there about two years.: Transformers can produce powerful electromagnetic fields, but there is no definitive answer on the safety of living next to transformers. Some people believe the electromagnetic fields cause health problems, and others do not. Bona fide research on health risks has produced sometimes contradictory results. One thing is for sure, high capacity transformers occasionally explode if they get overloaded, but these types of transformers are not allowed inside of buildings.

Q: I was wondering what year is transformer 2 cuz the first 1 was freakin awesome!!!!!!!!! and i wanted to see a second 1 but dont know which year and i heard there was going to be another one transformers 2.: 100% yes, i believe it will be out in august 2009, but not sure. they are making it as we speak.

Q: I have two questions:1. Can somebody please explain to me how transformer coupling is so good for maximum power transfer? Please be thorough. Is it because of the primary ac resistance and bjt output impedance being equal? I mean this should work because the power on the primary coil is the same as the power on the secondary coil so the power delivered to the primary coil which is the maximum power in this case, would ideally be delivered to the secondary coil, right? 2. And how can transformers be used to increase the overall voltage gain of a two stage common emitter based amplifier, something like: 1) Its basically impedance matching: the relatively high output impedance of the first stage can be matched to the much lower Hie input impedance of the second stage. Also any attenuation caused by the shunt resistance of the bias resistors working against the output impedance of the first stage (as shown in the R-C C coupled figure for question 2) can be eliminated by applying the bias network voltage at the low side of the transformer secondary, with that point bypassed with a capacitor to provide a good ac ground 2) Replace the 4K collector resistor with the transformer primary winding, eliminate the capacitor C3, connect the high side of the secondary directly to the base of Q2, connect the junction of R1 R2 to the low side of the secondary and add a capacitor from that point to ground to provide adequate low impedance at the lowest frequency of interest. Transformer coupling is efficient, but bandwidth is limited by the transformer, and the overall gain will vary with individual transistors. Both of these warts can be improved by applying negative feedback from the output back to the input stage.

Q: Is the upper oil temperature of the transformer high or lower?: Of course, is the upper high, thermocouple generally installed in the top.

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: I am throwing my sons 7th birthday party, and again this year it is Transformers. He is asking to have some unique foods as oppose to traditional party pizza. We, of course will still have a cake but I am drawing blanks to food ideas. Does anyone have any suggestions? Thanks in advance!!: Robot Party Food

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 hate feeling the need to justify myself, but I've seen a lot of answers telling askers to do their own homework. I'm trying to do so, but can't find any equations in the book relating power to voltage as well as turn number. Is it PviN? I've just seen Pvi, but that wouldn't apply to multiple loops. This is for ideal transformers by the way, so power for the secondary and primary coils is the same right? But are their vi's equal, or their viN's?The primary coil of a transformer has 200 turns and the secondary coil has 800 turns. The power supplied to the primary coil is 400 watts. What is the power generated in the secondary coil if it is terminated by a 20-ohm resistor?: The turns ratio is 4:1 of the primary. The power supplied to the primary is 400W. So regardless of anything else, in a ideal transformer, 400W is available on the secondary. But voltage will be 4x higher, current 4x smaller, than the voltage and current in the primary. Disregarding all that, if there is 400W of power flowing in the primary, then 400W will be being dissipated in the 20 ohm resistor. Watts in watts out, but secondary load (resistance) controls the wattage. There is no way to tell the output voltage and current, without knowing the input voltage and current. But whatever they are, the product of voltage x current will be 400W, in this instance.

Q: I think the power supply to my external hard drive has failed. Is there anyway I could replace the transformer. There is no way to contact the manufacturers as they have the worst customer services ever (Formac). I have emailed them 5 days ago without a reply.: Im assuming you are just talking about a plug in adapter with the transformer built in. If you look on the face of the transformer pack it should give you a VA rating and a voltage rating. You can buy a new one as long as you match the numbers. Hope this helps.

Q: how transformer came to know that it has to draw lagging current during summers: The transformer itself is inductive, as others have said, so it will always appear as a lagging load. Now, in the summer, most people are using their air conditioning systems, which are quite inductive because they're essentially just motors. So, the load attached to the transformer could be a good bit more inductive than in other seasons.
