Description

The application of the 370MVA/535kV main transformer power plant.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 370MVA/535kV main transformer power plant. 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 370MVA/535kV main transformer power plant, 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 have an old xray machine with a large step down transformer.Its not shorted but the paper insulation looks to dry. Is there a special oil for this? Thanks.: there is no oil for transformers. they are kept dry by all the heat they generate. it cooks the moisture out. if there is a specific reason you are worried, please do tell. is it going to be stored or go unused for a while? is there a lot of moisture in the area of operation? if not, i would not worry about it. it sounds as if it might be near the end of its life cycle as is. on the bright side transformers dont just burn out. there must be a reason for the failure. moisture is not too bad, but water is.

Q:Transformers of the three transformations are the three?: Transformer's three transformations are: The transformer can change the voltage. Transformers can change current. Such as current transformers. Transformers can change the impedance. Such as impedance converter. 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. Transformers can be divided into: power transformers and special transformers (electric furnace variable, rectifier, power frequency test transformers, voltage regulators, mine transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, Transformers, reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q:I LOVE TRANSFORMERS. From the box car days to beast wars. I played ROTF when it came out, it was pretty cool. Then WFC, epic. Now I'm wondering if I should get Dark of the Moon. I don't wanna get it and find out that people don't even play online. Or come to find out that this game is super weak and such. I just like the feeling of attacking then transforming into a jet (Starscream) and flying away. For you transformer fans, is this game a buy or Spend that money on another game situation? Tips and suggestions would be nice. Thanks!: I say don't do it. Too many times, I've played a movie/TV-based game and it sucked even when the movie was awesome. (Spiderman 3, Avatar, Avatar: The Last Airbender, Star Wars: The Force Unleashed, etc) Just don't do it

Q:about transformers: Your logic is valid but a careful look will tell what is happening. This strange behaviour is not that uncommon, it has analogy in other areas also. For example when you push a large stone, it is pushing you back (famous third law), then how does it move at all, if it cancels the supply force? On the other hand when you push a strong wall, it reacts with equal and opposite reaction. The thing is if the wall did not exert this reaction it would have allowed itself to be pushed back without any resistance!! These action / reaction like, supply voltage and induced emf (other examples are terminal volt of a d c motor and back emf, generator output and its reaction on prime mover etc etc) are all must be conceptually understood. I can dare say that they do not exist as such! They are merely way of understanding the concepts. When you supply ac volt to a coil (transformer without secondary load is just a coil) because of energy transformations taking place we see that the coil offers resistance much different from pure resistance, which is called impedance. But the same can be viewed as reduction of available voltage due to induced emf. I repeat this is a conceptual understanding of the phenomenon.

Q:I need a (step-down) Transformer of the following specifications:240VAC to 24VAC 10A or 240VAC to 24VDC.(Output as 24VDC would be better/easier).I live in Victoria, Australia and need one ASAP (next 3 days or sooner)Plz tell me any store or so Also, if u wanna know the VA Rating, its 240VA.If 10A is not available then anything closest to it. say 9 or 8.5 or 8 or 6.5.Cheers!: Transformers only work with AC, so the second choice is not possible. But you can buy power supplies that have a DC output. Reference has one possibility. Search google for buy supply 24v 10a and you will find lots more. .

Q:Hi,Should i wait for the Asus Transformer Pad Infinity, or should i buy the New iPad ?Thanks,Patrick: Hardware is negligible without software. The Google.play site (Formerly the Android Market) has plenty of apps to choose from. Basically, your investment is in the simplistic ease of the New iPad or the flexibility of Android 4.x. It's really a matter of which O/S you wish to support. I calculate the iPad IPS display has 25.7% more pixels than the new Asus model. Will you even notice the difference? Not at those screen sizes. Besides, the Asus has a 16:10 Ratio for a better movie experience. Personally, I have already seen that even the new iPad can't match wits with a Tegra 3 tablet when running certain games. Comes close, though. I'm waiting with baited breath for the Asus Transformer Pad Infinity. In my opinion, so should you.

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:around the house. Im looking for a step up transformer to handle 1.5VAC-18VAC with a ratio of 1:10 or 1:20. Which household objects would contain this??: well if you use a step down transformer in reverse, it might work. most power blocks will have it, the big heavy cube things you plug into a wall then into some device. a 12 volt power supply should in theory have a 10:1 step down take that in reverse and you'll have 1:10 step up 6-12 volt output block transformer is what you should look for (assuming your wall power is 115-120 AC).

Q:I was very disappointed with Transformers 2, there was no acting way too much action. Does anyone else feel the same way?: Same way, but for different reasons. There WAS acting, but it was over-acting. About a thousand times more than the first one. And now it's not just the pitiful human actors (namely Sam's new roommate, and again his parents) doing the over-acting, but the Transformers themselves: little former radio-controlled truck, Wheelie, somehow inherently born a Decepticon for no reason at all who talks smack at every chance. The Autobot twins, Skidz and Mudflap, no explanation needed. And the story was ridiculous. It was as if they had three or four plots and screenplays in front of them, then diced them up, tossed 'em in a hat and shook 'em vigorously, then glued it all back together in one heaping mess. As for action, that's what I showed up for. And ironically didn't feel there was enough of. They advertised an action-packed summer thriller with suspense and destruction, and instead they crapped out a comedy. Nice job, Bay. Now go away.

Q:How does a transformer effect amplitude modulation in an am transmitter. i would really love this to be explained from the basics as i am not so advanced in electronics. but i would really like to comprehend how this happens form the basics. thank you: The collector of the output transistor or plate of the output vacuum tube in a high power AM transmitter has DC voltage and an audio signal applied to it. The audio signal causes the the transistor/ tube to create AM. The AM radio frequency is shunted off to a tank circuit and then coupled to the antenna. A transformer is used to couple the audio signal to the transistor's collector/ tube's plate. A high power audio signal is applied to the primary side of a transformer and the secondary of the transformer is connected in series to the DC power source to the output device. This creates a varying DC voltage to the output device which creates Amplitude Modulation.
