Description

The application of the 360MVA/63kV 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/63kV 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 the 360MVA/63kV 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: Transformer ratio and transformer ratio: Transformer ratio K and transformer voltage on both sides U1 U2 winding turns N1 N2 current I1 Ⅰ2 have a relationship! In the ideal case, the ratio K = U1 / U2 = N1 / N2 = I2 / I1

Q: How do transformers work detailed descriptions please. Also how are the voltages stepped up or down?: A transformer is a device that can be used to increase voltage and decrease current (or vice versa). It uses AC power and is based on Faraday's law of induction (mutual induction). A transformer is made up of two coils, each with a different number of turns, linked magnetically through a soft iron core. The magnetic flux from one coil links the other through the core. When the flux in one coil changes, the flux passing through the other will change, inducing a voltage (emf) in the second coil. The coil connected to the AC power source is known as the primary coil (number of turns Np), while the coil in which voltage is induced is known as the secondary coil (number of turns Ns). If the primary coil sets up a changing flux, the voltage in the secondary coil depends on the number of turns in the secondary. The transformer is assumed to be ideal in which the resistance of the coils is negligible and all the flux in the core links both primary and secondary windings. There will be no energy loss in an ideal transformer.

Q: how do i work out the voltage output of the second winding on a transformer if i know the Primary voltage is 35v and the first winding has 355 windings and the second winding has 4500 how do you do this ?thanks: Assuming that the transformer is designed for a primary voltage of 35 or more, then you can simply multiply the applied primary voltage (up to the design limit) by the turns ratio and this will give you the output voltage. In this case: output voltage 35 x 4500/355 444.

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: An AC generator, originally designed to provide a peak output voltage of ± 155 V at a frequency of 60 Hz, is required to provide a peak output of ± 340 V at 50 Hz. If the generator is connected to a transformer with 200 loops in its primary coil, how many loops should there be in the secondary coil in order to provide the required output?Using the formula Np/VpNs/Vs I get 439 coils, but this is too easy for a 6 mark question and doesn't include the change of frequency. I have no idea what to do and need some help :(: Your answer is correct. The frequency has no effect on the turns ratio. The frequency does effect the required primary inductance, however. More turns with 50Hz, about 20% more for same magnetizing current as with 60Hz. I am assuming your generator can change frequency.

Q: Transformers of the three transformations are the three?: Take a 10kV / 0.4kV, d / yn11, 100kVA transformer rated voltage full load operation: 1, the high side of the 10kV into the low side of the 400V; 2, the high pressure of 5.77A into low pressure side of 144.4A;

Q: Can a transformer alone be used for amplifying audio signals ? If yes how ?: Technically No. The transformer will not amplify a signal, however it can be used to make sure you use any signal you actually do have to your best advantage. A transformer is generally used to achieve an impedance match between the signal source and load. For instance if you were to connect an 8 ohm speaker directly to a 1 kilohm signal source, most of the available signal would be dissipated in the source resistance and less than 1% of the signal would produce movement in the speaker. If however a 1k to 8 ohm transformer is used to match the source to the load,up to just under 50% of the signal will make it into useful energy in the speaker. This is a substantial gain in performance of the overall system but is not actually amplification.

Q: Do you know what that show is called where there are these dinasaurs, and there are good oens, and bad ones, very similar to transformers.The dinasaurs transform into robots. Whats it called?: I don't know. Are you sure you aren't combining Extreme dinosaurs with the dinobots from Transformers? The only other cartoons I can think of staring good and bad dinosaurs are Dinosaucers and Dino-riders. Is it any of these? Around what time is it from? Edit looking at the other answers Beast wars had Dinobot on the Good side and Megatron as a dinosaur on the bad side

Q: A liter of transformer oil how much jin: According to the density of the transformer oil can know, a liter of transformer oil weight should be 0.895 kg, which is 1.79 kg. Transformer oil: is a kind of oil fractionation products, its main components are alkanes, cycloalkyl saturated hydrocarbons, aromatic unsaturated hydrocarbons and other compounds. Commonly known as Fangpeng oil, light yellow transparent liquid, the relative density of 0.895. Freezing point <-45 ℃.
