Description

The application of 1500MVA/1000kV AC UHV 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 1500MVA/1000kV UHV AC 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 1500MVA/1000k 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: 80 kilowatts of electrical appliances need much transformer?: The selection of the transformer is based on the current. 80KW electrical current is 210A210 times (380 multiplied by 1.732) 138kva above the transformer can

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: A want to know what happens to transformer when it is overloaded. Where i can get information about this: Yes the transformer will burn and blast if overloaded.It results due to heating effect

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: Power transformer parameters: First, the transformer technical parameters The main technical parameters of the power transformer are: rated power, rated voltage and voltage ratio, rated frequency, operating temperature class, temperature rise, voltage adjustment Rate, insulation performance and moisture resistance, the main technical parameters for the general low-frequency transformer parameters are: transformer ratio, frequency characteristics, nonlinear distortion, magnetic shielding and electrostatic shielding, efficiency and so on. A. Voltage ratio: Transformer two sets of coil turns are N1 and N2, N1 for the primary, N2 for the secondary. In the primary coil plus an AC voltage, the secondary coil will produce both ends of the induced electromotive force. When N2> N1, its induction The electromotive force is higher than the primary voltage. This transformer is called a step-up transformer: when N2 <N1, its induced electromotive force is lower than the primary voltage, which is called a descending transformer. Primary secondary voltage and coil The number of the following relationship: where n is called the voltage ratio (turns ratio). When n <1, then N1> N2, V1> V2, the transformer is a step-down transformer.

Q: What is the main purpose of the transformer?: When a sinusoidal alternating voltage U1 is applied across the primary coil, there is an alternating current I1 in the conductor and an alternating magnetic flux ф1 is generated which forms a closed magnetic path along the core through the primary and secondary windings. The mutual inductance potential U2 is induced in the secondary coil, and ф1 also senses a self-inductance potential E1 on the primary coil. The direction of E1 is opposite to that of the applied voltage U1, which limits the size of I1. In order to maintain the existence of magnetic flux ф1 need to have a certain power consumption, and the transformer itself has a certain loss, although the secondary load is not conne

Q: I want to step down a 240Vpeak signal to 24. Anyone know where I can get a transformer to do this? Also does frequency have a dependence on a transformer? The signal I am looking at has around 55Khz frequency. Thanks for your help: You won't be able to find a transformer for that frequency, unless you are lucky. You will have to wind your own. Probably a ferrite core is best, depending on your power level, which you did not mention, and is an important design factor. If this is a very low power signal (you do use the word signal), perhaps a capacitive or resistive voltage divider will be enough. Or search for an audio signal transformer. .

Q: How to use the experimental method to determine the transformer iron consumption and copper consumption: No-load test for iron loss; short-circuit test copper loss. I suggest you read the book, see the information.

Q: How does the core material affect a transformer? Such as if you use steel vs. air. Or wood vs. magnet.: A transformer is a gadget that converts an alternating (A/C) modern of a definite voltage to an alternating modern of diverse voltage, without substitute of frequency, via electromagnetic induction. A 'step up' transformer gets a low voltage and converts right into a miles better voltage, and a 'step down' transformer does in basic terms the opposite.

Q: I have been telling everyone that I would never get the IPad because it doesn't do anything. A tablet is a great idea, but the IPad has way better potential. The IPad is currently useless. You could have music, movies, web on the go, books and games with an ITunes App store. Those are pretty much the highlights.The Asus Eee Pad Transformer on the other hand is a tablet that has music, movies, web only with wi-fi, books games, Android App market, and what i'm really looking for in a tablet, the ability to view and modify microsoft office documents (word, excell, power point). The advantage that the Transformer has is a detatchable keyboard, so it can be used as a type of netbook or tablet. The plus about the keyboard dock is that when your tablet needs charging and you connect it to the dock, it will recharge your tablet. Total battery life of the tablet plus dock is 16 hours(8 hrs/e).So now, is ther anything out there similar to this Eee Pad Transformer worth considering? Should I get it or not?: ASUS Eee Pad Transformer Tablet is very responsive and has lots of apps that provide me with convenience and entertainment. The keyboard layout is better when you rotate it upright than when it is in landscape mode. There is a nice bezel area to hold the tablet without getting your fingers onto the screen. Says on the website you can sync it with your home computer, but I haven't done that yet. I think I might buy the keyboard dock because typing on a touchscreen is very slow. PROS: Fully customizable Tons of apps(honeycomb apps are growing) Great price Gorilla Glass Cons: Short charger cable no usb port besides the one that is for charging and connecting to computer
