Description

The application of the 840MVA/550kV three 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 840MVA/550kV three 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 840MVA/550kV three 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:I am making a small Tesla Coil, but have a question regarding the transformer. Would it work to simply wind one myself with the correct winding ratio to get the voltage I want (around 7-10kv) or is it better to stick with a commercially available transformer? (I would rather not have to buy one) Any advice for winding a transformer?: you okorder

Q:advantages of power transformers: Another advantage can be, depending on the application, isolation between primary and secondary circuits.

Q:I have an an iPod touch with 3.0 and I installed a jailbroken app called Transformer. It makes thr iPod look like an iPhone. But when it resprings, nothing changes. Please Help!: I feel your pain, but Transformer only works on itouches with the firmware 2.2 or under. If your still want a iphone look-a-like this is what I did and I works great Maybe even better than tranfromer!: 1. Download iCall, textPlus, and Flicket off app store. 2. Download CompassF app off cydia. 3. Download theme iPhoney theme off Cydia 4. Download Better 3G WiFi (turns wifi bars into 3g) 5. turn on the 2 themes ATT bars will be added w/ iPhoney automadiclly 6. Download SBSettings, extras, and turn on the numeric battery. (like 3Gs) 7. Lastly, if you want to go that extra mile Im working on a Theme that changes the iTouch settings to iPhone ones with wallpaper on main page. And thats it, the Icons and names of the 3 app store apps should change to camera, messages, and phone. The spotlight should say, Seach iPhone and thats pretty much it. Not only does the phone work with wifi now looking just like the iphone dialpad, and so does messages. So I think this is better than Transformer and wont mess up ur touch like transformer would. Hav fun messing with your friends minds lol! :)

Q:How to understand the secondary side of the transformer: The side of the step-up transformer voltage is called the secondary side Buck side of the transformer voltage is called the secondary side In fact, by the power through the winding to stimulate the magnetic field called the primary side by the magnetic field induced by the energy called the secondary side If the three-winding step-down transformer voltage is the highest side of the second side of the winding is the second side

Q:I really want a better transformers than 4 1 was great 2 was crap 3 good 4 worst of them all: Yes, there will be a Transformers 5. When we don't know. Many people are thinking 2016 or 2017, but i have a friend that works in the movie theater and she knows the next movies for the next 2 years and Transformers 5 was not on the list. Is that because Transformers 5 has no name yet? Maybe. So Im assuming its coming out in 2017 or 2018. As for Paramount pictures they are not even thinking about Transformers 5 yet. As they stated once its one movie at a time.

Q:I took apart a wall transformer before and soldered a single AA battery to the outputs and touched the what was before inputs and it gave me a shock. This is because it stepped up the power to something like 113v. Could I instead of a AA battery use 110 from the wall. Would it do the same thing. Or would it just overheat the transformer. And what would the amps be. I’m trying to make like a 20amp welder for just screwing around with.: A battery will not work with a transformer. Transformers rely on alternating current (AC), whereas a battery provides only direct current (DC). The voltage at the output terminals will be zero, except for the instant at which you connect/disconnect the battery. Be very careful working with transformers, as they can create deadly voltages. Also, connecting/disconnecting an inductor can create enormous transient voltages across the terminals (especially if a DC current was applied), causing a spark. The step-up equation for a transformer is V1/V2 N1/N2 For example, if you connect the 110VAC wall outlet to a 10,000-turn solenoid, and the output terminals are connected to a 200,000-turn solenoid, the output terminals will be 2200VAC. Alternatively, due to conservation of energy, the current will be inversely proportional to the winding ratio.

Q:I use transformers in my circuitry all the time but when a transformer is say a secondary 12v 1a transformer than what does it mean by 1 ampis it that the secondary winding wire will pop after 1 amp doo to the simple thinness of the wire? or that the ohms of the secondary coil, when using iv/r, 112/12so does this tell you that the coil is 12 ohms?please don't give me other information about the transformer just answer the question please.: It means the transformer secondary voltage is 12 volts and the current rating is 1 amp. If you put a higher current load on the transformer it won't pop, but it will overheat and the insulation will degrade faster than if the current was kept below 1 amp. If the current is allowed to go too high, the transformer will fail in a short time.

Q:New on the transformer reported to stop, how to do,: First, if it is the implementation of non-industrial nature of electricity, there is no need to apply for stop procedures, directly out of the transformer on it.

Q:hi guys can any of you give me advice on wot i need 2do on removing and replacing a faulty line output transformer on a rear veiw projection tv as i have the part and the local tv shop wont fix it 4 me.wot would be the best way to discharge the power from it first and could i jus cut the 2 wires on the old 1 and use connector blocks to connect the new 1 in would this be ok to do or do it need to soilder connected on?. and is there any adjustments that would need to be done to the set when i have it installed be4 i turn it on any help much appreicated: Solder the joints!!!!It is OK to use the old connectors!!!! Be sure that the power of the new transformer it is the same with the power of the old one.

Q:I will be living in Germany for a while and I'm trying to plug my TV in, as well as one or two other things. The 1000 transformer I have works, but whenever I plug in the power strip to plug in more things than just the tv, it will automatically blow the power in the house and I have to go flip the switch again. Other Americans I know here in Germany do not have this same problem. I need help!: Hi, The 1000 transformer the is mentioned is not too clear. However, since transformers are rated in power like watts in small designs and volt/amps as they are larger, I will tend to feel that the transformer you are using is a 1000 watt unit. If it is so, then that 1000 watts is the total power it can transform. A thousand watts is not a large quantity when it comes to televisions and other modern electronic equipment. Depending on the size of the television, that alone can use up the power of the transformer. The transformer would have been protected with a suitable fuse or breaker to prevent overloading by the users. Hence the breaker will trip on overload to protect the transformer. Check the power consumption of the appliances that you want to use.
