Description

The application of 1500MVA/1000kV AC UHV Transformer can significantly improve the economy of the UHV substation, 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 1500MVA/1000kV UHV AC transformer. 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 1500MVA/1000k 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 UHV Transformer products.

Q:Hi, thanks for reading my question. I'm an electrician with some basic knowledge of electricity but this is puzzling me. In the USA, a single transformer on a pole means split phase. Three transformers on a pole means 3 phase. What does two transformers mean? Is it split phase with a high leg?Thanks: That is an excellent question. A single phase transformer is referred to as a split phase because it is center tapped. What that means is that the transformer as a whole is 240V with a wire tapping the coil in the center and grounded to create two separate 120V legs. The single phase transformer is essentially split into two pieces which is where the split phase terminology is derived. Three phase banks are three separate transformers working 120 degrees out of phase which is an ideal balanced setting for three phase commercial load. You can almost create true three phase using two transformers. The phase separation isn't ideal, but it does work when three phase service isn't available or a single phase service is needed in addition to a three phase service off the same bank of transformers. The term high leg is derived from the non-ideal phase orientation which creates a higher single phase voltage on one leg. BTW am I the only one tired of seeing one or two know it all people answer all the engineering questions even when they obviously haven't got a clue?

Q:A buddy of mine has some new old stock DVDs at his store. He has the G1 Transformers Seasons 1-4 boxsets by Rhino. They are in mint condition and factory sealed. He said if I want them he will throw in the G1 Transformers movie(Rhino version) and the 20th anniversary version both factory sealed. He will sell me this DVD collection for $300.00Is it worth it? Are these DVDs worth that much money? I would like to own the G1 series I just want to know if this is a fair price.: Even though the original Transformers series is brilliant in it's animation, voice acting, and overall robot-lazer battle-isciousness; it most definitely is not worth that much money. Even if the special features are epic. However, many websites have links to the episodes online, so you can watch the OG Transformers over the inter-tron. Or the gumple-tron, which is an entirely unexplored medium of wireless communication yet unknown to humans.

Q:even in a dc transformer, the cause varying current though not in polarity, can cause a change in the magnetic flux linked with a coil.: Transformers are used for obtaining a voltage which is different from available supply voltage. The supply voltage on the primary induces a magnetic field in the primary coil. This magnetic field is shared by the secondary coil, in which depending on the number of turns ( coils), a voltage is induced. To induce magnetic field, we need a relative movement of supply source and the medium where it is induced. In AC, since the voltage is varying in magnitude and direction, a stationary primary coil can get induced to produce a magnetic field. In DC, since there is no change in direction, voltage will not get induced in a stationary primary coil ( except during the switching transient conditions. i.e On and off times). Note that the fundamental requirement for induction is rate of change of flux.

Q:hello. I've been thinking about this long and hard. you see ever since I was 2 years old I've been collecting transformers figures and other items. now that I'm getting older I know I must let go. but its kind of hard when for the first 8 years of m life my transformers were all I had. and I know when we die we will leave these things behind. but it seems so hard to let go. so what would you do if you were in my sitiuationcause this is very hard for me and i'm lost. I know in heaven we will all be happy but it seems weird to me will I not remeber transformers?if anyone has any ideas that would be great thanks.: WHY DO YOU HAVE TO LET GO OF WHAT YOU LIKE? YOU CAN BECOME A PROFESSIONAL TRANSFORMERS COLLECTOR, AND TURN YOUR INTEREST INTO A MONEY MAKING CAREER. YOU MIGHT MAKE YOUR FIRST MILLION BY THE AGE OF 16, WHO KNOWS?! THESE PEOPLE IN HOLLYWOOD ALREADY MADE TRANSFORMERS INTO A MUITI-BILLIONS BUSINESS, SO CAN YOU! LETS HAVE FUN GET DOWN TO THE BUSINESS.

Q:how could I describe the physics of transformer?: A Step up transformer is outdoors a skill station and will enhance the voltage for the skill lines so it may bypass swifter and better parts. A step down transformer is after the skill lines to shrink the voltage and making it secure for domicile use.

Q:I didn't. I even watched it at I-Max with my boyfriend and a few friendslets just say I wasn't the only one falling asleep. It was long, too long. They could have cut it down by at least 30 minutes.: i liked it, but not nearly as much as the first one. the robot fight scenes were WAY too long and there were a lot of lame one liners

Q:Devices that convert the car battery's 12 V DC into 110 V AC are easily available. The conversion from 12 V DC into 110 V AC is done in 2 steps. One circuit in the device changes DC into AC and transformer changes the voltage. Does it matter which step is done first and why?Any help would be awesome! Thanks!: a device which converts Direct current into Alternating current is called an INVERTER - - - a TRansformer NEEDS Alternating or ( in this case PULSATING Direct current ) in order to work -- so an INVERTER has a circuit which makes PULSATING Direct current - - - There are several designs -- and If this circuit puts a current in L one TRansformer primary winding to ground Stops theninto L two TRansformer primary to ground - on and off over and over -- - - the secondary will have a REAL Alternating current output - google INVERTER Design / INVERTER / Silicon Controlled Rectifier INVERTER Design --- the Voltage Step up done last ( second Step ) -- because the TRansformer NEEDS the first Step ( a circuit to make an REAL ac or PULSATING dc in order to function )

Q:If a power surge from a house shot back towards a transformer, would it ground the charge or bypass the transformer and harm the surrounding wires?: No, the transformer itself wouldn't ground it. I don't know if they have some kind of surge protector, by the transformer would just 'pass it on' (most likely blow a fuse if the trannie survived

Q:I use a 1000 watt transformer for my tv, dvd player, cd player, game cube and nintendo (only 2 can be plugged in at a time or it is a fire hazard). The transformer is very strong and flips the circuit breaker if anything else in the house is plugged in and I try to plug that in. I'd rather not have to unplug everything to plug it in but I am worried I am wasting electricity if I keep it plugged in. So my question is does transformers use energy if they are plugged in and the appliances plugged into it aren't turned on? Also, do you think I can use a smaller transformer for those items listed above if it does use energy? The boxes that I buy them in don't say, they just say what watt they are.I've tried to look it up but I can't understand any of it so thank you in advance for helping me.: I can't say that I fully understand your situation but, transformers do use energy even when the load is in an off state. The transformers job is to convert and provide power. It does this if the device is either on or off.

Q:How do step up transformers obey the law of conservation of energy?: The regulation of conservation of capability is that capability won't be able to be created or destroyed. A transformer does not make extra capability,yet rather it takes the voltage and will boost it , this might seem to push aside the regulation yet rather in basic terms making extra it reduces the the present. As voltage will boost by using say 10 circumstances the amperage a million/10 of the orginal.
