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: A transformer rises the voltage in proportion of 1 to 10. If the power in the primary coil is 100 watts, we should expect a power of ____ watts in the secondary coil. a) 10b) 100c) 1,000: As that of primary:100.

Q: I really want a better transformers than 4 1 was great 2 was crap 3 good 4 worst of them all: Yes there will be a Transformers 5. Michael Bay said that they are certain that there will be a 5th. Sorry to the haters. Just saw the 4th, so something tells me 5 should be good.

Q: How many transformers games are for the xbox360 and what ones are based on the old tv show? And what ones are based on the movies? Please give complete names and in order! Thank you (:: Movie: Transformers: The Game (2007) Transformers: Revenge of the Fallen (2009) Transformers: Dark of the Moon (2011) Non-Movie: Transformers: War for Cybertron (2010)

Q: i just obtained a transformer from a small ac-dc converter. usually, it converts the 240v ac (let's call it terminals a and c) to 4.5v dc (terminals d and c).what if i connect a 4.5 dc supply to the terminals d and c? meaning that where i would usually obtain the converted electricty, instead, i connect a 4.5 to it, leaving the terminals where i would usually connect to the wall empty. wouldn't the magnetic field step up to 240v?: Short answer, NO. Your power converter is not a reciprocal device. While a transformer is part of the circuitry, it is most likely a switching converter. If you're talking about the transformer only, then you need to feed an AC signal in to it. Feeding 4.5VDC in to the transformer will short out your 4.5VDC supply, or cause it to supply lots of current which will be converted to heat.

Q: I have been reading wikipedia and have gotten confused.Va.Number of Coils on side a---- ._________________Vb.Number of Coils on side bwikipedia mentioned how power companys use transformers for converting to high voltage power li nes then use transformers to bring the voltage back down.Focusing on the transformer that jacks the voltage upwirea-[side a-Transformerxyz- side b]-wirebso assum wireb is the high voltage power line.--Which side of transformerxyz would have more coils ? My guess is that side b has more coils then side a--Is it safe to say that the wattage of side a is equal to side b?--they said something about magnetic flux, does this just mean that the material connecting side a to side b has to be magnetic?--they said that the insulation wears down in transformers over time due to heat. what is causing this heat?--they said something about leakage and spacing of coils, what does this mean?tyVVVVVVVm: The previous answer is correct, but the following may be helpful. A transformer works by the linking of changing magnetic flux produced by one loop or coil (the primary winding) with another coil (the secondary). That is why transformers only work with alternating current or pulses. Magnetic iron has the ability to increase the magnetic flux produced by a coil. This is called its magnetic permeability and can increase the flux produced by factors of several thousand or more. Leakage flux in a real transformer is the amount of flux produced by the primary that does not link the secondary. This flux is wasted and reduces the efficiency of the transformer. Heating of the wire insulaltion not only comes from the resistive heat of the windings, but also the heat produced in the magnetic material (core) of the transformer. These losses are called eddy current and hysteresis losses and can be quite substantial. The reason that cores of transformers are laminated (stacked thin sheets of magnetic iron) is to reduce the eddy current losses.

Q: S11-1250kVA transformer oil capacity how much: S11-1250kVA transformer oil capacity is 550kg, the pressure of the relevant information will be marked on the nameplate, the nameplate has the relevant parameters.

Q: 10 (6) /0.4kv three-phase transformer what does it mean: Three-phase five-column core transformer must be used YN, yn0, yn0 connection, in the transformer must be connected into the angular connection of the fourth winding, it is not out of the beginning (the structure to do the electrical test when the lead is not This case). 5). When the transformer of different connection group is running in parallel, the general rule is that the connection group label must be the same. 6). When the distribution transformer is used in the multi-mine area, the Yzn11 connection method can be used. When the z-connection method is adopted, the impedance voltage algorithm is different from the Yyn0 connection method, and the copper consumption of the z-way winding is more. Yzn11 connection distribution transformer lightning protection performance is better. 7). Three-phase transformer with four volumes when the core frame can not be used YNy0 connection. 8). These are used for the domestic transformer connection, such as the export should be required to supply the appropriate connection and connection group label. 9). Generally in the high-voltage winding are connected with the tap-changer. Therefore, when selecting the on-load tap-changer (including the on-load tap-changer and the off-circuit tap-changer), it must be noted that the transformer connection and the on-load tap-changer (including connection, test voltage, rated current, Level voltage, voltage range, etc.). YN connected to the on-load tap-changer used on-load tap-changer, it is also important to note that the midpoint must be able to lead. ?The answer is recommended by the questioner

Q: i wanted to know what the new transformers movie about?: its about transformers.

Q: Is the transformer a power adapter?: Power adapter is a transformer, it should be said that the power adapter is a transformer, rather than that the transformer is a power adapter. Like Baidu is the site, the site is not Baidu ah.

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.
