Description

The application of the 260MVA/800kV single phase water cooling main transformer for the 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 260MVA/800kV single phase water cooling main transformer for the 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 260MVA/800kV single phase water cooling main transformer for the 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:How to test the transformer capacity: If the temperature rise of a transformer is less than 55 degrees, it can be considered to achieve the design capacity. ? As the temperature rise test time is long, the customer can not track the whole process, some bad transformer manufacturers in which mischief, cut corners, made the transformer can not reach the design capacity.

Q:Can a electrical transformer have more the 1 input, while only having 1 output so that the power is combined into the 1 output,or would multiple inputs make the power feed back onto the other inputs and overload them.: Yes they can. There are two and three phase input transformers in common use that do this all the time. What is important though, is that the power sources for each phase are properly synchronized. Essentially this type of transformer Has three input windings and singl eoutput winding, that provides a single phase output that takes its power form the other two or three phases. Again, having the right phasing is critical when hooking up a transformer like this.

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:I would like to input DC9V voltage into 12V, 15V multi-channel, how to do the details of the master: DC circuit using the transformer, first of all to DC into AC (switch conversion), that is, with switching power supply. On the switching power supply is more complex than the proposed purchase of finished DC-DC module. Select the appropriate DC-DC module according to the required voltage and current.

Q:A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil.A How many turns of wire does the secondary coil have?B When the transformer is running at full power, what is the current in the secondary coil?C The current in the primary coil?I know what equations I would use, but I don't have enough information to use them. Can someone at least set these up and show me how to plug the numbers I have into the correct equations?: A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil. Power output Power input Power Volts * Amps 350 13,000 * amps Amps 0.0269 amps current in the primary coil? House voltage 120 volts 350 120 * amps Amps ≈ 2.92 current in the secondary coil? Amp Ratio 2.92 ÷ 0.0292 100 : 1 Wire ratio 100 : 1 A How many turns of wire does the secondary coil have? 50,000

Q:A 120-V, 60-H air conductor is to be operated in a remote area where the voltage drop in the long transmission line results in a utilization voltage of 102-V. Determine:A) the required step-up voltage ratio for the satisfactory performance.B) The voltage ratio of a standard buck-boost transformer that most closely meets the requirements of the loadC) The voltage at the load with the buck-boost transformer installedD) Sketch the appropriate connection diagram and show the NEWM standard terminal markings: A set-down transformer

Q:I really want a better transformers than 4 1 was great 2 was crap 3 good 4 worst of them all: Unfortunately, there probably will be

Q:1.) What is the function of a transformer?a.) It is a device that can change the voltage of an AC supply.b.) It can change a low voltage supply into a high voltage supply or vice versa.c.) It is a device used mainly to change AC into DC.d.) A and B are correct.2.) What is the function of a transformer at a power station?a.) To convert DC into ACb.) To produce very high voltagesc.) To produce the currents in the power linesd.) None of the above.: Sorry but I don't know about this

Q:What is the meaning of the high voltage side and the low side of the transformer?: High voltage side called high side of the low voltage side called low side

Q:I need a flyback transformer for some plasmatastic experiments. I know a place where someone dumped a bunch of broken TVs and computer monitors. Where should I be looking for a flyback transformer in this stuff and what can it look like?thanks: The frequency of an ac power supply is only 60 hz. That's way too low for a flyback. The resistance of a transformer depends on the frequency. At 60Hz a flyback transformer acts like a short circuit. It would draw a lot of power, might damage the power supply and nearly nothing would come out the other side of the transformer.
