Description

The application of the 25MVA/110kV railway balance traction transformer, 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 25MVA/110kV railway balance traction 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 the 25MVA/110kV railway balance traction 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:I need this Radio Shack transformer to provide power to a HO scale model train board lighting system. This transformer will be connected to a brightness control system and then the brightness control system will be connected to building lights and street lights. I have been told this issue is a safety and Electrical Code concern?: a acceptable web site. Face the construction south with residing house windows in basic terms in the south elevation. the north elevation could the two have a small variety of small residing house windows or be breamed with earth. For an present residing house, Geothermal is huge in case you have the money. the traditional forced warm air gadget that maximum US properties has is likely considered one of the main effective for the preliminary value and maintenance in comparison to the warmth is generates. A German business enterprise, called viessman (sp) creates very useful structures for this configuataion.

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 use a 1000 watt transformer for my tv, dvd player, cd player, game cube and nintendo (only 2 can be plugged in at a time or it is a fire hazard). The transformer is very strong and flips the circuit breaker if anything else in the house is plugged in and I try to plug that in. I'd rather not have to unplug everything to plug it in but I am worried I am wasting electricity if I keep it plugged in. So my question is does transformers use energy if they are plugged in and the appliances plugged into it aren't turned on? Also, do you think I can use a smaller transformer for those items listed above if it does use energy? The boxes that I buy them in don't say, they just say what watt they are.I've tried to look it up but I can't understand any of it so thank you in advance for helping me.: Any transformer will use electricity when the device is not turned oncell phone chargers are the most common. A transformer or is just a coil of wire going from one prong to the other in that plug.

Q:A step up transformer increases 17.7v to 120v. what is the ratio of the current in the secondary compared to primary? Assume 92% efficiency.HELP PLEASE: Sec Curren Ratiot 17.7/(120*0.92) 0.136

Q:First of all, try not to be bias ;). My birthday is on December 19th, exactly the release date of the Transformer Prime, which is a great tablet, one I think surpasses even the iPad 2. With Steve Jobs gone and the new quad core installed in the Prime, would the iPad 3 be likely to be better than the Prime? Should I just wait for an iPad 3 if so? Thanks :)!: First of all, don't forget that the iPad 3 hasn't been announced and it will probably be a few months, at least, before it comes out. Secondly, there are sure to be spec improvements and additional features in the iPad 3. Whether they match up to the Transformer Prime, however, is anybody's guess. Third, I think the real decision should come down to if you want the Apple environment or the Google environment. Last I checked there are more iOS apps than Android apps, and if you have a Mac, iCloud is a nice thing to keep everything in sync across devices. I personally like iOS, its interface, and the way updates are delivered (as opposed to with an Android device, updates Google produces may not coincide with a new product release or may not be available right away for your device). On the other hand Android is more open, the integration with Google Calendar and all is great, there are less restrictions on what apps are allowed in the Android store, and if you are happy with Android then there's no real reason to wait for the iPad 3.

Q:Power industry, Taiwan change, Taiwan, transformers in the concept of what is the difference? Also, what does the measurement point mean? First into this line, hope you brothers help.: Metering points are generally placed on the two sides of the equipment for property rights demarcation point. Some "real production boundaries" are not suitable for loading tables, the measurement points can be located in the substation, if the measurement point and production to the demarcation point is different, the asset owner should bear the loss of their own property equipment. For the substation of the various routes, the measurement point is located in the various routes on the outlet. Transformer two transformers run parallel to the situation is very common. Parallel operation can make the power quality better, and better play the potential of equipment and so on.

Q:Who knows the density of the transformer oil is how much?: Temperature at 20 ° C: Normal value typical 25 # transformer oil: 895kg / m3 877.6kg / m3 45 # transformer oil: 895kg / m3 879.0kg / m3

Q:Do any adults play that game online anymore? I am 19, big fan of transformers since I was a kid watched the G1 series, Transformers prime, seen the michael bayfail movies and played all the games. I love TFFOC its a gream game, with great unique multiplayer and its in cybertron! I love it and can't wait for the next game as that will be on Earth!.I have been playing this game for quite a while now and everytime I put my headset/mic on and play a match online I always come across kids that are like 13 years old and get friend requests from them lol.Should I stop playing this game?: Kids like to play games about robots maybe? If this is bugging you then stop playing for a bit then try again another time to see if its not just kids anymore, I mean they grow up right? :)

Q:How do you use transformer efficiency in problems? Is it just VsVp(Ns/Np)(efficiency) and IsIp(Np/Ns), or is it something more complicated? Does efficiency affect both Voltage and Current?: Transformer efficiency (usually between 85 to 98 percent) is more of a function of transferring power, I x E or I^2 x R. Usually with the transformer's secondary looking into some kind of Load. So, you would say that transformer efficiency is a function of (Ps / Pp) x 100, or [I x Es (rms) / I x Ep (rms)] x 100 effiiciency of the transformer. Efficiency factor affects both votlage and current (power) in exactly the same way.
