The application of 1140MVA/500kV Three-phase integrated 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 1140MVA/500kV Three-phase integrated 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 the 1140MVA/500kV Three-phase integrated 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:Transformer question electrical machine?
The transformer is connected delta-wye (mesh-star), so the secondary voltage is: Vs400V x sqrt(3) 692.82V (line-to-line) Current in each resistor is: IrE/R692.82V/20ohm34.64A Line current on secondary is: Ils34.64A x sqrt(3) 60.00A Current in each secondary winding: Isw Ils 60.00A Current in each primary winding: Ipw Isw 60.00A (because windings are 1:1) Primary line current: Ilp Ipw x sqrt(3) 60.00A x sqrt(3) 103.92A Check: Primary and secondary kVA should be the same: kVAp400Vx103.92Axsqrt(3)/100072.0kVA kVAs692.82Vx60.00Axsqrt(3)/100072.0k It checks Since load is purely resistive, kVAkW. Total power: 72.0kW Power per resistor: 72.0kW/3 24kW
Q:Are He-Man, Transformers and G.I. Joe still popular?
Yes. Transformers and G.I Joe is Still running through the Veins of this Generation, But He-Man is Kind of Not So Popular They Don't even Show He-man TV Show in channels, He-Mans drop was his costume that Gave him a Gay look. Transformers and G.I.Joe is still being watched, So there are more than 4k Fans
Q:friedland d753 door bell transformer?
Although, I have not tested a unit like you mention, I would get the 1.5a unit because that is the maximum it puts out in amperage. If your bell uses less its OK
Q:What are the transformer capacity?
The size of the transformer capacity, usually based on the required power supply unit to determine the size of the power supply, with the voltage level is different, the voltage level product capacity is not the same. Voltage levels from 10KV ~ 1000KV range. The conventional capacity starts at 10KVA, and as the voltage level increases, the capacity increases accordingly. For example: 10KVA / 10KV, 500 / 10,2000 / 35,31500 / 66,40000 / 110,100000 / 220,240000 / 330,400000 / 500 and so on (due to too many types, but also the unconventional capacity of the transformer so Can not be simple summary).
Q:Looking for a transformer?
If you don't find it you have got to make it. This is a common transformer. Probably you are finding difficulty with it's current rating.
Q:Funny scenes from Transformers?
When the car turns into bumblebee and the guy says to the girl its probably japanese
Q:Transformer in Consumer Electronics?
You are right. The value of a coil is measured in Henries and is determined by number of turns, size of wire, type of wire (commonly copper or aluminum). That is the reason you should not leave adapters and chargers plugged in. When not in use they should always be un plugged from power source.
Q:Auto Tapping Transformer?
Thank okorder
Q:How do transformers work, no not the robots.?
Transformers can e used only for A.C the fluctuating current in the primary coil produces a magmetic field.this magnetic field by mutual induction makes a current in secondary coil The no:of turns in primary and secon determines thr rating of transformers more the no:of turns more magnetic field will be produced in primary and less the no:of turns in the secon lesser will be the current induced and vice versa For more details visit
Q:who loves transformers??????
YEAP! i do. haha. Cause i love movies with cool things like Journey to the Center of the Earth --LOVE THIS MOVIE!
