The application of the 150MVA/345kV three phases self coupling generator interconnection 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 the 150MVA/345kV three phases self coupling generator interconnection transformer. 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 150MVA/345kV three phases self coupling generator interconnection 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q:Transformer issues?
500 kVA ÷ 0.380 kV ÷ √3 760 amps The nameplate rating (kVA) of a transformer is designed for 50% insulation life after being loaded to nameplate kVA and running with a top oil temperature of 110 °C for 20.55 years. (180,000 hours) Since your ambient temperature is not constant, and the equipment does not run continuously, the transformer's insulation will last far longer. In most real world applications, if a transformer is not loaded to nameplate, it will theoretically last for more than 100 years. Many electric utilities load their transformers beyond nameplate to take advantage of this overly long life. Motor Inrush: As for the motor starting inrush, the missing factor is how often the motor starts. If it is only seeing an inrush once an hour, the transformer can handle an inrush of 4x nameplate. Your motor's inrush of 1700 amps is 1700 ÷ 760 2.2 times nameplate. According to a transformer manufacturer's table, a transformer can handle an inrush of 2.2 times nameplate more than twenty times an hour. I highly doubt this 450 HP motor is starting and stopping every three minutes. You are good to go with the 500 kVA transformer.
Q:physics transformer output and input question. help?
just read your text book. lets say we have a transformer with a turns ratio of 10:1 If we apply 20 V on the high voltage side, (the side with the higher turns ratio aka 10:1), on the other side it will have 2 V. This is because of the turns ratio. Lets say that the power input on the high V side is 100W. So the current on the high V side is 100W/20V5 A Assuming ideal transformer with no losses, power in is power out. So on the other side, you will also get 100W. So the current on the low V side is 100W/250 A Basically, going from one side to the other, the V increases and the I decreases to keep the same power on both sides, as according to the turns ratio. I hope that you can figure out how the turns ratio of 10:1 made sense here. I better get best answer for this, lol. But seriously, read the text book, see how the turns are wound see how the electric field makes a magnetic field, which makes the electric field, etc.
Q:Transformers 2: Revenge of the Fallen?
I think its again about the cube
Q:buck-boost transformer question?
A set-down transformer
Q:What kind of transformer is required to convert a 110 v microscope with a 6v, 10w bulb to a 220 v instrument?
What do you accomplish by converting a 110v appliance to a 220v appliance.
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:150KVA transformer can withstand much power, how to calculate
150KVA is the capacity of the transformer, it can output the maximum power is 150KW. KVA = KW capacity number is the number of power without calculation
Q:Why is Transformers Fall of Cybertron full of kids?
Kids like to play games about robots maybe? If this is bugging you then stop playing for a bit then try again another time to see if its not just kids anymore, I mean they grow up right? :)
Q:Help with a Toroidal Transformer. best answer will get max points!!!!?
DC power into most transformers will result in smoke output. All transformers operate on AC. Your description leads me to believe that this is a power transformer with two outputs (not a Toroidal). 26.2 vac ORanGe 0 v (ground) BLacK 26.2vac YELlow and the other output 14.0vac BLU 0v (ground) BLacK/BLUe Your info does not indicate how many amps you can draw from the outputs, but I would suspect that it would be small (1 amp). The 26.2 vac outputs can be used without the ground to produce 52.4 vac output. It is normal for these two outputs to be out of phase.
Q:question about a transformer?
There are four shoe transformers. I am assuming you are talking about the ones that look like Nike Free 7.0 Running shoes made by Takara and available in Japan. There is Convoy ( Red White and Blue), Megatron (Black and Grey), Starscream ( Maroon and Black), and Marine Convoy ( White, Blue). These are exclusive to japan. However since there is no picture, I can also assume you may have a Kids meal shoe Transformer from Subway. Good luck!
