Description

The application of the 380MVA/525kV single-phase double winding generator 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 the 380MVA/525kV single-phase double winding generator 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 the 380MVA/525kV single-phase double winding generator 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:(1) A Step Up transformer steps up voltage.(2) Voltage is directly proportional to Power.Conclusion: A Step Up transformer has the capacity to increase Power.Contradiction: By First Law of Thermodynamics, Energy can neither be created nor be destroyed. Hence No one can create energy out of thin air like, that of by just using a Step Up transformer to increase voltage and hence power.Where is the whole theory wrong?: P I*V A step up transformer DOES increase output voltage BUT it also lowers output current. So it's incorrect to say that Voltage is directly proportional to Power. Voltage is Power divided by the Current. If the output voltage doubles, output current drops by a factor of 2. This way, total output power stays the same as input power, and all laws of Thermodynamics are satisfied. P_in I_in * V_in I_out * V_out P_out

Q:Is the upper oil temperature of the transformer high or lower?: Of course, the upper oil temperature is high ah, the liquid convection effect ah.

Q:I need a transformer to use american electronics in Ireland, any websites that sell Type G transformers?: You need a step-down transformer to reduce the 230 VAC to 115 VAC for your American devices. The web site below is one good source. It has transformers to step voltages up or down. A transformer is the best way to go as opposed to a voltage converter that just uses a voltage drop. Make sure the transformer you get has enough power capacity to supply everything you want to connect to it.

Q:I have scavenge many transformer, but how do I know its VA rating (in order to utilize it without damage it)For voltage rating, we can measure using Multimeter, but what about maximum capable ampere ? Or we can only estimate by judging size of it ? Would be glad if there is a way to measure other values too !: Transformer Rating

Q:Transformer oil filter method: 2, vacuum oil filter to ensure that there is a certain number of power, taking into account the size of your transformer, oil pillow position level, the oil filter is too small may not go oil cycle 3, the oil circulation from the oil pillow on the opening of the valve, where the best open after the bandaged, to prevent other debris in the filter oil fall into the transformer oil pillow. 4, filter oil after a certain time, take oil samples. Qualified to stop the oil filter, add the oil inside the oil can be closed after the oil pillow upper check valve. The transformer can be powered by one night after standing.

Q:explain the role of both types of transformers in getting electric energy from an electric power plant (coal-fired, natural gas or nuclear) to our homes.: A step UP transformer is used to boost the VOLTAGE, as by doing so the CURRENT is reduced by the same factor, e.g. boost voltage by 100 x, reduces current to 1/100th. By reducing current, power losses due to the transmission line RESISTANCE is very significantly reduced, especially in long run distances between consumers and the generating plant. The formula I^2*R is power, and the square of (say) 100A is 10,000, whereas if the current were reduced by 100 fold as above, the current becomes 1A., so you can see the difference! 1^2 1, versus 100^2 10,000. But the voltage is too high for consumer use, So a step DOWN transformer is used to change the voltage down to the required domestic voltage. The ratio of this transformer can easily be adjusted to allow for the minute power lost in the high voltage lines. The overall effect is very much less power lost in heating the connecting wires in the transmission lines, so much more power available to consumers.

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:New on the transformer reported to stop, how to do,: Second, if it is a large industrial electricity price, in order to save the basic electricity costs, is the power supply enterprises can apply for disabling procedures, but the new transformer need to comply with the "power supply business rules" provisions, reported there are two procedures, Capacity, the second is suspended: Article 23 of the Power Supply Business Rules The user will be required to apply to the power supply company five days ago. The power supply enterprise shall handle the following provisions: 1. The reduction must be the whole or the whole group of the transformer to stop or replace the small capacity transformer power. The power supply company shall, upon the date of acceptance, seal the equipment according to the date on which the user applies for the reduction. From the date of the seal, according to the original billing method to reduce the corresponding capacity of the basic electricity. But the user stated that the permanent reduction or from the date of the expiry of the expiry of two years without the resumption of electricity procedures, and its capacity after the reduction has been less than the implementation of the two-tier price of capacity standards should be changed to Single system billing;

Q:Why the computer water does not use transformer oil: In terms of cooling medium, the cooling effect of water is very good, it is used in the weak is the most used to achieve the purpose of cooling and the lowest operating costs.

Q:e in the past with followings already??? I'm just curious I mean Transformers is at 700 mill where everything else is in the 300 mill range which isn't a bad thing but I'm just wonderin'thanksand please give like 5 or more sentences, not a because it rocks: Because most boys/men like toys and things that blow up, plus throw in a barely dressed skank and there you have it!
