Description

The application of the 250MVA/220kV standby transformer power station, 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 250MVA/220kV standby transformer power station. 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 250MVA/220kV standby transformer 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 UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in te

Q:I have 3 transformers that for some reason burned-out . I say burned- out because that's what it smelled like when they stopped working. If you have a reason why this is happening please include with your instructions on how to repair them if it's possible. These transformers are 120v input ,12v output. Thank You RE: Halogen Lamp Repair

Q:I have just receive a gift from friends aboard. it is a transformer Universe Cyclonus with Nightstick. A Deluxe sized toy with Targetmaster partner.I have never heard about that. what is Transformer Universe? Is it a company similar as Takara Tomy?: Transformers: Universe is a Transformers comic series and toy line that introduced repainted versions of past figures. The Transformers: Universe toy line traces its origins back to when Hasbro imported the Transformers: Car Robots toy line from Takara and called it Transformers: Robots in Disguise. Although they made most Hasbro versions of the Car Robots characters, they also released a number of repainted molds from previous toy lines and released them as part of the Robots in Disguise line. When the Robots in Disguise line ended and Transformers: Armada started, the repainted product line was given its own title: Transformers: Universe. If you want to see more informations in detail, strongly recommend you to visit its official site or Yahobby online store for product list.

Q:I am looking into purchasing a counter top coffee roaster that requires a 30 Amp 120 outlet; manufacturer says it uses about 21A.The only plug/circuit that can handle this load at this time is a 240 V outlet. We have a gas stove and we are not currently using the circuit.Does anyone know of a manufacturer that makes a external/freestanding step down (240 to 120) voltage transformer / regulator that I can plug into a grounded (North American) 220V outlet ? Note: a) I don't need it to be variable, just a fixed 240V to 120V is perfect. b)It would also need some sort of internal voltage regulation/ stabilization as erratic voltages would affect the (coffee) roast.: If each leg of the 240v circuit is 30 amps, you won't need a transformer at all. There are travel kits for going to foreign countries that have a variety of adapters for plugging into 240V outlets that only use one leg of the circuit, which is 120v. Find the adapter that fits your outlet, and you will be up and running! DO NOT TRY TO MAKE SUCH AN ADAPTER YOURSELF UNLESS YOU HAVE A DEGREE IN ELECTRICTY/ELECTRONICS! Using a transformer involves balancing the load, getting a transformer that is rated for the current, a lot of worms in that can. There are also adapters available to stabilize the current, they are available wherever compurers are sold.

Q:does anyone have the trailer for transformers: No there is no trailer yet because there is no footage yet. The film is currently 'in production' and will hit cinemas next year. Look for a teaser soon enough.

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:I have a small question concerning flyback transformers. I have run into some confusing problems when i tried testing the flyback using the High voltage power supply project: You might find whether your transformer is broken with an ohmmeter between the ultor cap and a pin by trying each with the meter set to a high ohms range, with (I think) the black meter lead connected to the ultor. If you don't see a result 1st. time around, try swapping the meter leads. If you get a result, try the 24V test there. If you don't, and using his method also fails, I think you have a dud. So far as the 9V test, I think that has a fatal flaw. A digital multimeter, or usually also an analogue one, cannot respond fast enough to a single pulse. A digital meter only samples at a certain rate, and if the voltage does not align with the sampling, you see nothing. Even if it does, I think you would only see an instantaneous reading before next sample sees nothing. Apart from that, the voltage spike will be well over 200V! The object is to sort out input direction in the primary. I would suggest you sort out the primary connections, and build the circuit. I have not looked at it, but I think if you fire it up, you will either have + HV coming from the ultor cap, or nothing. If nothing, reverse the primary. DON'T TEST IT WITH YOUR FINGERS!!!

Q:50KVA transformer maximum load is how much?: 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.). The circuit symbol is commonly used as the beginning of the number.

Q:I have a transformer of 12060 Volts and a transformer of 15000 Volts, both neon-sign types; if I wired them together, would it amplify the output voltage or have a catastrophic effect that would end the world as we know it?But really, can I wire them together for an added effect of some kind?Thanks.: If you connect the output of one to the input of the other, you will have a catastrophic effect immediately. You could connect the inputs in parallel and two outputs in series but you need to know how to get the phasing right. You will get 27000 volts. PS The series connection will work poorly or not at all if the transformer conains a switch mode power supply. PS2 You also need to deal with the effects of an internal connection between the output and the transformer case.
