Description

The application of the 370MVA/535kV main 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 370MVA/535kV main 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 370MVA/535kV main 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: How to test a Current Transformer (CT) ? thanks in advance: k

Q: I have a question can someone explain why transformers get hot in use and why must they not be allowed to get too hot: Simple explanation: a transformer can actually be modeled as an LRC circuit where the L is in series with the R and are both in parallel with the C. L is the inductance R represents the lossyness of the inductor and C represents the capcaitance between the turns. The heat comes from the loss of power through the resistance of the coil. and this lossyness can be described by the Q (quality factor) of the inductor. Q can be described as w(Total Stored Energy/Avg power dissipated) here w is the operating frequency.

Q: About a month ago, i studied Ohm's law which said voltage is directly proportional to electric current. But today when i was studying about transformer, it said that if number of turns of the secondary coil is more than that of primary, then the induced voltage is higher than the primary voltage which was supplied and the current throught the secondary coil is less. How can this be? If voltage increases, current should also increase right? And what is the difference between emf and current?: Power stays constant on both sides. As P U*I, that means if one of either voltage or current increases, the other one must decrease. emf is basically voltage. The U R*I is also valid, but if the two coils have different number of turns, they also have different R values.

Q: Transformer is not the main and vice two coils? Resistance into which ah?: Transformer calculates power factor If the capacity of the power transformer is denoted by S, the output active power is expressed by P, then the power factor cosa = P / S.

Q: I am build a band pass filter but I am wondering if one of the inductors in my filter can act as a transformer at the same time. I'm assuming not since it would be sending all its magnetic energy into the secondary rather than back into the primary. Can someone confirm this for me please? Also, if it DOESN'T act as an inductor than would it be okay to put it in parallel into my filter? Or do I put it in series? Where do I put it lol?Thanks: The primary of a transformer has a fairly large inductance called the magnetizing inductance. This inductance could be used as a filter, but it is not a good idea. First of all, it will not support any appreciable DC current, because it will saturate. In addition it is usually very nonlinear. If you want to filter the input voltage use a separate filter.

Q: Power industry, Taiwan change, Taiwan, transformers in the concept of what is the difference? Also, what does the measurement point mean? First into this line, hope you brothers help.: Transformer refers to equipment; Taiwan change is installed in a place of the transformer, is specifically installed, running a transformer; Taiwan area refers to the regional range of variable power supply. Metering point is for the two sides to determine the installation of electric energy meter position, in general, the measurement point should be set at the demarcation point of property rights.

Q: 1. 6volts going in a 12:220v transformeris the output 220v or less, formulas, computations 2. 12v going in 12:220v transformer (1 amp 220VA)core loss, copper loss, eddy current loss etc etc3. 24v going in a 12:220v transformer. is the 220v, lost of power in the input,: If the enter is 24 volts, the output would be 440 volts, yet do no longer try this via fact which you will likely dissipate the transformer. you could word any voltage below the rated enter and the output would be proportionately decrease. in case you word 6 volts, you will get a hundred and ten volts out. i wish this enables.

Q: can any one give me a fast time line of transformers history: The gods Primus and Unicron nearly destroy the universe fighting until Primus tricks Unicron by imprisoning them both in metal planetoids. Unicron becomes giant transforming world devourer and Primus becomes Cybertron, bringing to life the transformer race that will fight Unicron in his stead. The robots of Cybertron eventually begin civil war which go on for millions of years, the evil Decepticons vs the heroic Autobots. Unicron finds Cybertron, the Autobot leader destroys him with the Matrix, the transformers fulfill their destiny. Their war continues until Cybertron is nearly depleted so the planet is reformatted and the race adopt Maximal and Predacon castes. New wars begin until balance is struck and Cybertron becomes technorganic paradise

Q: i need a transformers costume that can transform into a car, truck, etc i need to buy it for this kid for his birthday. medium size please. and he wants it as optimus prime.he wants it to look good and if he doesn't like it, well hes gonna be sad: wrap urself in tin-foil. lol

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.
