Description

The application of 500MVA/765kV substation auto-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 application of 500MVA/765kV substation auto-transformer. In order to make the products applicable to any substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity 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 500MVA/765kV substation auto-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 OLTC Transformer products.

Q: I am doing a school project of a Wind Turbine; and I need to show a transformer or what a transformer is in a wind turbine. I have just 1 question. WHY DO PEOPLE USE TRANSFORMERS?: Kiran okorder

Q: 1.Is there going to be a Season 4?2.If there isn't,then is there going to be a new Transformers series?: Transformers animated ended last Saturday with Endgame part II. It was ended because of the movie coming out and Hasbro wanted to focus on movie merchandise. There's been some talk of maybe it starting up again after the movie or even a new cartoon.

Q: Calling all fans of Transformers! I am looking for anyone to tell me if Transformers Animated is coming back for a third season on Cartoon Network. The reason why I am asking this question is because I recently bought the second season of the show and noticed that they have a lot of information on new characters as a special feature and I am wondering if those characters will be in the third season of the show.: That would suck sooooo bad if it is cancelled. All that build up in the first season with super villains and no Megatron and like, 3 Decepticons till the end of season 2 for what! To take it all away just as its getting good and finally setting up a full on Autobot Decepticon war There better be a season 4 or this series will go in the forgotten bin with Robots in Disguise as another series that took forever to set just for 1 big battle then that's the end. But if it is the end then that will teach the writers for holding out on what fans really want. I can not sit through season 1 or 2 again, except the season 2 finale.

Q: Transformer Lightning: Transformer lightning strikes may result in damage to the transformer winding insulation due to overvoltages

Q: I'll be going to Peru for 2 weeks and I was wondering if I could plug in my electronics over there. I read that they have both North American and European outlets and the voltage is 220 V and 60 Hz. My iPod wall charger and phone charger say 100~240 V (and my laptop charger says 100-240 V) and 50/60 Hz. Would I need to buy a transformer while I'm there so my stuff doesn't get all burnt out?: most south american and north american countries are the same plug sockets and voltage. also you can but anything there

Q: i heard that there is an electric transformer used in single phase electric furnace and other applications , its benefit is to get more balanced current load from the three phase system to feed a single phase load.i need to know how its can transform three phase supply into single phase supply, and if it can be used in reverse matter i.e can it deliver a three phase power from single phase supplythank you in advance: You would get the same voltage out of one output as if you had connected all 3. The other 2 would have lower voltages across them. For example, say the transformer was normally a 240 to 480 3-phase delta. If you were to put 240 across legs A and B, you would get 480 across A and B of the output. I believe the B/C and C/A outputs would have 240 each, since the unconnected C phase would appear as a center-tap to the A and B legs

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 would like to know if its possible to create my own transformer- preferably by producing my own windings. My goal is to make an open-air transformer encased in an acrylic box. I would like it be able to withstand a 15A load at 120V. I want the windings to be 1:1 so that the power is just transferred through the magnetic field, not stepped up or stepped down.The purpose would be to power my PC through it, just because I think it would be cool to look at the box and imagine the energy transferring through the air to my screen. Obviously, it's doing that out in the street, and a thousand other places before it gets to me, but I don't get to see any of it!Any one have any suggestions? If it's way to difficult or expensive to make my own inductors, what kind of inducts would I need to buy, and how close would the need to be to each other?: a 15a load is way more than you need for a PC, which probably needs 1 or 2 amps at the most. If you really want to make a 15*120 1800 watt transformer go ahead, but it's a lot more work than a 1*120 120 watt one. You will need a transformer core, which you can buy, or salvage out of an old transformer of the proper power level, and a lot of wire. You need to calculate the proper wire size and number of turns, and get enough enameled wire to do that. Transformers are not made of inductors or inducts, but of turns wound on a laminated iron core. Make sure the box has ventilation holes in it, as this may get hot. You do realize that a mistake may result in lots of smoke and perhaps a fire? And you could get burned, or electrocuted? And your terminology leads me to believe your knowledge in this area is close to zero. Be sure to use fuses as part of your design. Use the buddy system, have someone within hearing distance at all times with a fire extinguisher, and that person should have knowledge of what to do to cut the power. .

Q: I want to multiply current 10times for a second or two. So, is there any easy way to do that without using a high power transformer?Thanx.!: If your output is 8V ac, then a transformer is unfortunately your best bet. You can get real fancy and do a switching power converter/inverter (sort of like the inverters that convert 12V dc in vehicles to 120V ac), but that solution is outside the ability of most designers. You would lose a lot of hair and if you're lucky, it MIGHT be cheaper. ************************************** I'm assuming you want to conserve power and increase I by a factor of 10 while decreasing V by a factor of 10? Remember; P V*I A switching regulator will allow you to transform power from one form to another very efficiently (often 90% or better). It uses an inductor switched cleverly between the source and load. This is used in most modern power supplies instead of a transformer (like laptop supplies, cell phone chargers etc.) Your question is a little vague you can increase current 10 times by reducing the load impedance (resistance) by a facto of 10. Ohms law VI*R or IV/R. Reduce R by 10, increase I by a factor of 10. Hope this helps, Dave

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.
