Description

The application of 32MVA/220kV 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 32MVA/220kV 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 32MVA/220kV 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 a 150 watt bank of photovoltaic cells that run at 12 volts (PWM mode non-mppt charge controller). My question is, by substituting a dc transformer (one that boosts current and steps down to 12v) for a current boosting mppt, can I run the solar panels at their full rating even though they are connected to a 12 volt battery bank? The 12v batteries, when directly connected to the solar panels, drop the output because the panels output their full current at a higher voltage.I am also wanting to apply this logic to a wind turbine that outputs a maximum of 30 volts dc. I am thinking that if the switching transformer works for the solar panels, it would also work to step down the wind turbine's harsh dc voltage to a current boosted 12v state. Would this theoretically work?: Transformers don't work on DC. You need a DC to DC converter.

Q: I need a flyback transformer for some plasmatastic experiments. I know a place where someone dumped a bunch of broken TVs and computer monitors. Where should I be looking for a flyback transformer in this stuff and what can it look like?thanks: Whatever okorder

Q: I want to know how much the current will increase. But the transformers i'm looking at VCT VT10000 - 10,000 Watts Heavy Duty Continuous Use 110V / 220V / 240V Step Up / Step Down Voltage Transformer or 15,000 Watt Step Up and Step Down Voltage TransformerI figure the whats is the total possible power and if you divide the power by the intial voltage you get the current and if you divide by the out put voltage you get the final current? but what if you input doesn't equal 15000 watts or whatever the power is?: the power output of the transformer depends upon transformer ratio. transformer ratiosecondary voltage/primary voltageOR no. of secondary turns/no. of primary turns in this case, transformer ratio220/1102. and transformer's capacity is denoted in KVA or VA. also, a transformer can only transform power(increasing voltage levels while decreasing current level and, vice versa), but it can't change the amount of power. the power of a transformer will remain constant for any input. hence, if the input voltage decreases, the input current increases, making the power a constant. for a step up, output or secondary voltage will increase, magnitude depending upon the transformer ratio.

Q: everyone's been fighting about if jazz from transformers is white or black i think he's just white pretending to be black what do you guys think: Jazz is always voiced by an African American actor, Scatman Crothers, Darius McCrary, Phil Lamaar, but even though Transformers have varying ethnic voice actors, or for some reason, a human foreign accent, they're one race and not considered white or black, or foreign no matter what part of Cybertron they come from. They're either Autobot or Decepticon, and they're allegences, not races. They're Cybertronian by birth, Decepticon is a faction name created by Megatron, and Autobot is the governing force later changed to the title of the good guys amidst the war. I think it's just tradition for Jazz to have a African American voice and sound cool on acount of his name

Q: I want to get all the DVD'S for the transformers animated series and i was wondering how man series there are and what all they are called. if you could just give me the names of the series and tell me if they are on DVD or not. thanks for the help!!!: Transformers G1: On DVD Beast Wars: On DVD Transformers Armada: On DVD Transformers Energon: On DVD Transformers Cybertron: On DVD Transformers Animated: Season 1 is on DVD. I'm not sure if there were any other seasons made. Transformers Prime: Not on DVD I think this animated series is pretty new. There may be a DVD release in the future, not sure. I hope this helps!

Q: I know that in a step-down transformer if I have 10 turns on the primary coil and 5 turns on the secondary coil that the voltage gets reduced by half and the current gets doubled, but is there any other significance?: The magnetic flux generated by the current is proportional to the number of turns of the coil.

Q: Here I am building prototype transformers for testing, using 1 ft length aluminum conductors of 1/2 by 1/2 inch width square conductors. I am structuring the (aluminum square tube)windings(connected at corners by ordinary round copper wire) in return layer diagonals, ( the pattern set by odd magic square sequences) to establish maximum internal capacity in the windings. If the current in the windings is opposite between every internal lateral square facing, most of the external field around the windings is cancelled, but internally between the windings the magnetic loops will be in unison. I therefore wish to put insulated steel tube sleeves around the internal aluminum loops of the wiring array, for a very unconventional honeycomb type core transformer. I should be able to measure for eddy current output on any steel sleeve by shorting the ends of the outside steel segment with an amperage meter. A conv. secondary will also need copper loops wound lengthwise around the steel.: An AC transformer connects AmpereTurns in the Primary to AmpereTurns in the Secondary using the time varying magnetic field in the core. The maths for the size of the core is well established. If you double back on turns they do not count as part of your ampereturns - unless you shield the doubled bit. Such methods are used in shaded pole motors. The only way to lighten the Tx is to use higher frequencies in the core. This 'dumps' the magnetic energy into the secondary more often so you can use a smaller core (bucket of energy!) The magnetic field is always perpendicular to the current and hence so are the core loops (in a Vector Notation sense - not necessarily physically) If you introduce Iron windings in the windings space you will get bigger Ohmic Losses. I hope this helps - you obviously have a plan to make hyper-efficient Tx but they are already near 0.999 efficiency.

Q: advantages of power transformers: it is used to step-up or step-down the voltage when used to transfer electrical energy over long distances. to put it in simple terms - the voltage is stepped up from the power generation plant so that there is a minimal loss of electrical energy when it is being transferred through wires. and it is stepped down when it reaches the destination for usage.

Q: I broke a small transformer that I found inside of my DVD player, and I would like to have one (not for the DVD player, just separately) I would like the transformer to take in low voltage, such as a few AA or AAA batteries, and I want it to scale that up. Does anyone know where I can get one? If not are there any instructions on how to make an effective yet inexpensive one?Thanks in advance!: A transformer cannot step up or step down DC power. (All batteries are DC). That is part of their nature. A basic transformer is nothing more than two (or more) inductor coils in close proximity, often with a steel core to help with the magnetic fields. All inductor coils are basically a coil of conducting wire, most often copper.

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
