Description

The application of the 150MVA/345kV three phases self coupling generator interconnection transformer.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 150MVA/345kV three phases self coupling generator interconnection transformer. 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 150MVA/345kV three phases self coupling generator interconnection 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q: Transformers, broken, how to repair: Some of the transformer buried inside an insurance, first look at the said

Q: If I have a primary coil and secondary coil each with 400 turns that acts as a transformer, and the primary potential difference is 2.988 V, and the secondary potential difference is 0.0551 V.I need to find the efficiency. Ideally, it would be 100%, but this is the real world. So I did N(turns) and Volts and used the equation [N(p)V(s)/N(s)V(p) ] *100%p primarys secondaryNturns of coilV potential differenceI had an answer of 1.84% which seems awfully low. Help please. Thanks!: You are right. The efficiency is that low. Take a look at it another way: Pin Pout if 100% efficient. Since we know a 1:1 turns ratio will produce the same voltage from one side of the transformer to the other, the current produced on the secondary is extremely low to pull the voltage down to .0551V. It makes this transformer extremely inefficient! I can't even think of how you would design a transformer that was this inefficient. I think even a large OD iron nail with a lot of eddy currents at 7.5k Hz I believe would be more efficient. The next worst way I can think of how to produce an isolated output is with a TEC using the Seabeck effect that is about 6% efficient.

Q: i am planing to get the eee pad transformer, can it download anything from the internet browser just like a computer does or it can only download apps from its own app store like ipad does. should i get the transformer or ipad 2 ?: Well, it does really depend on what you are searching for! If I am not wrong, the transformer can be put into a dock? and also includes android 3.0 the newest software made by google now, which offers you some custom roms and more freedom in your tablet while the iPad 2 is made by apple. Well, I have tested it my self and have noticed that it is just perfect! Processor (A5) Memory and more components. Although I recommend you take a look at the motorola xoom or wait for the next models of samsung galaxy tabs which will be thiner and will contain a bigger screen of 10.1. Just wait for the moment because the technology is really changing. Nvidia tegra 2 is included in the transformer_! Keep that in mind, one of the best gpu's available right now!

Q: I am build a band pass filter but I am wondering if one of the inductors in my filter can act as a transformer at the same time. I'm assuming not since it would be sending all its magnetic energy into the secondary rather than back into the primary. Can someone confirm this for me please? Also, if it DOESN'T act as an inductor than would it be okay to put it in parallel into my filter? Or do I put it in series? Where do I put it lol?Thanks: The primary of a transformer has a fairly large inductance called the magnetizing inductance. This inductance could be used as a filter, but it is not a good idea. First of all, it will not support any appreciable DC current, because it will saturate. In addition it is usually very nonlinear. If you want to filter the input voltage use a separate filter.

Q: 10 (6) What is the meaning of 10 and 6 in the KV transformer?: One, 10 (6) KV transformer in the actual use of mostly oil-immersed transformers. It is also a distribution transformer, one of the important equipment in the industrial and mining enterprises and civil construction power supply and distribution system, it will 10 (6) kV or 35kV network voltage to the user to use the 230 / 400V bus voltage. 2, 10 (6) KV transformer 10 and 6 refers to the transformer primary side (input) voltage level is 10kV or 6kV. That is what we usually call the voltage of the high voltage line. It is mainly to 10 (6) kV network voltage down to the user to use the 230 / 400V bus voltage, which is commonly used in our 220 volts and 380 volts AC.

Q: Hi there, I live in the Dallas, Texas area and we recently had a lot of storms come through. During one of the storms I was looking out a window to my backyard when I heard some thunder and saw some lightning hit the transformer right outside my backyard, which sent sparks everywhere. The power went out, but came on about a minute later.Ever since then (it's been about 24 hours) all the lights in the house have been dimmering every few minutes, some lights dimmer when you turn on appliances and one outlet went out randomly.: Hi, You should check out first with your neighbours and then with the power house. In case if the problem is with your lighting then you will need to get it fixed. You can opt for LED light bars as they are easy to install, consume less power and are long lasting. They are cost effective and reduce the cost of maintenance.They provide equal amount of light like the traditional sources of light while consuming less energy. So you can save on the electricity costsas well. Cheers

Q: Do stores that sells computers, printers, etc. also sell transformers: Transformers as in the action figures? You can find them at Toys R Us, Wal*Mart, or Target.

Q: Can the transformer be replaced with a component?: If you say the transformer is a small power frequency transformer, then you can use switching power supply instead. If the substation with high-power transformers, there is no thing to replace.

Q: Why the computer water does not use transformer oil: What is the cooling method used in electrical appliances and what cooling medium is used by the use of the environment and conditions of the impact

Q: Why can autotransformers be used as safety transformers? Isolation transformer is a variable ratio of 1 transformer, why has a security role?: The high and low voltage side of the autotransformer is realized by tapping in a coil, and there is no magnetic connection between the two times and there is an electrical connection, so it can not be used as a safety transformer. Isolation transformer high and low voltage coil is separated, the only magnetic connection between the two there is no electrical contact, so the role of security protection.
