The application of the 360MVA/63kV main transformer for Hydro power station.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 360MVA/63kV main transformer for Hydro power station. 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 360MVA/63kV main transformer for Hydro power station, 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:Do transformers (110V-220V) drain much power?
No okorder
Q:How do you choose the public transformer capacity?
In the actual choice, should adhere to the "small capacity, dense point" principle Distribution transformer location should be located in the load center, and the power supply radius of not more than 0.5 km. Distribution transformer load rate between 0.5 to 0.6 the highest efficiency, At this time the capacity of the transformer is called the economic capacity. But if the load is relatively stable, then the continuous production of the situation can be selected according to economic capacity transformer capacity.
Q:What is Transformer: UNiverse?
Transformers: Universe is a Transformers comic series and toy line that introduced repainted versions of past figures. The Transformers: Universe toy line traces its origins back to when Hasbro imported the Transformers: Car Robots toy line from Takara and called it Transformers: Robots in Disguise. Although they made most Hasbro versions of the Car Robots characters, they also released a number of repainted molds from previous toy lines and released them as part of the Robots in Disguise line. When the Robots in Disguise line ended and Transformers: Armada started, the repainted product line was given its own title: Transformers: Universe. If you want to see more informations in detail, strongly recommend you to visit its official site or Yahobby online store for product list.
Q:Transformers, where to start?
Q:Pulse Transformer timing?
Pulse transformers can be wound to any turns ratio that is desired. That being said pulse transformers have small cores and therefore handle small amounts of power. You can find cores on those old mother boards that are no longer in service and junk computer power supplies also have a couple of cores. These toroids were normally used as filter inductors to remove spikes from DC or low frequency lines. You can easily rewind them for pulse transformers.
a) (5,000/200) x 900V 22,500V. (5,000/200) 25:1. b) (20 x 25) 500A. c) (900 x 500) 450,000W. (22,500 x 20) 450,000W. (450KW). Both must be the same, if no losses.
Q:Transformer Efficiency Question?
Transformer efficiency (usually between 85 to 98 percent) is more of a function of transferring power, I x E or I^2 x R. Usually with the transformer's secondary looking into some kind of Load. So, you would say that transformer efficiency is a function of (Ps / Pp) x 100, or [I x Es (rms) / I x Ep (rms)] x 100 effiiciency of the transformer. Efficiency factor affects both votlage and current (power) in exactly the same way.
Q:why isnt megan fox going to be on Transformers 3?
lets all be honest Transformers 3 is going to blow balls they are over doing this whole series way to much. Can anyone say cash cow. The quality is gone.
Q:Parallel Operation of Transformers?
I don't recognize your transformer designations in a) and b). Perhaps they are industrial transformers that I am not familiar with. My background is electronics, not power distribution. That being said, I'm not sure why you would want to connect transformers in parallel. Possibly to handle a load that exceeds the capacity of one transformer. If this is the reason, it would be better to split the load between two transformers if at all possible. If it is a single load that can't be split, the turns ratios for the two transformers would have to be exactly the same. For that matter, the transformers should be exactly alike, to make sure that they carry the load equally. (A higher source impedance in one transformer would cause the other transformer to carry more than its share of current.) Then it is very simple: connect like terminals together, taking special care to line up the phases. If for some reason you are unable to identify the phase (commonly marked with a dot next to the winding on a schematic diagram), do the following: 1. Connect the primary windings together, wire 1 to wire 1, wire 2 to wire 2. 2. Connect one wire in the secondary of one transformer to a wire in the secondary of the other transformer. 3. Carefully apply power. 4. Measure the voltage between the two loose secondary wires. It should be zero. If not, change one of the wires in step 2 above.
Q:Transformer Transformer Principle
The transformer is a high-pressure water (electricity); outlet is a low-pressure water (electricity)! Transform pressure is buck! Reverse can also! Pool to increase the pump Change the high pressure water! Transformers to replace the iron! Like low-pressure water sealed water tank at the bottom of the high-pressure water! Understand it! Haha! I as a lecturer?
