Description

The application of 32MVA/220kV 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 32MVA/220kV 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 32MVA/220kV 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: What is the meaning of the transformer capacity unit KVA?: KVA for apparent power, its size and power factor! For example: power factor cosΦ = 0.8 active power P = 1Kw Then tgΦ = 0.75, so the square of the apparent power S = the square of P + the square of P * tgΦ When the power factor is 1, 1KVA = 1KW

Q: b)Describe an important industrial application of one of the above devices (apart from transformers)C)Explain how this device works-that is ,what the electricity actually does: A transformer is a device that allows you to easily and efficiently convert an AC voltage to a different voltage. When you do this, the current is converted in the opposite ratio. For example, if you have a 100 volt 1 amp source and you convert it to a 1000 volt source, it will have capability of 0.1 amp. It is made by winding wires on iron cores. See the reference for details. It is very important for the transmission of AC power, as it can be changed to a very high voltage for efficient distance transmission, and back to low voltage for use in homes. .

Q: I love the movie transformers and cant wait till part 2.Anyone know anything about it specifically???: The combat scenes have been much extra extraordinary in this one than in the 1st movie plus that they had some extraordinary new characters. i'm unable to %. only considered one of my admired areas from the recent Transformers so i visit %. my precise 3, all of them are from the combat scenes. a million. while Optimus top rips that significant robotic's face aside together with his hooks precise in the previous he gets killed himself. 2. while Optimus top tells the Fallen that he needs his face and rips off a million/2 his face in the previous stabbing him with that sick weapon. 3. while the very previous Deceptagon who became to the Autobot facet includes help in the extensive conflict scene and slices one guy in a million/2 in the previous getting attacked via the robotic panther. He then yells i'm getting too previous for this crap precise as he squashes the panther under his fist. classic. there have been many different great moments and scenes and it became into quite this summer season's blockbuster and became into quite nicely well worth the money for the value ticket. Megan Fox became into warm in it too yet she became into quite not the only relaxing area of this movie.

Q: If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts? Please help, thanks so much!lt;3: If you connect them in series, you will get 24 volts. It's not a real good idea to connect them in parallel.

Q: S11-1250kVA transformer oil capacity how much: The total amount of oil in the transformer: the amount of oil supplied by the transformer body transport + (the amount of oil required to be added to the main body) + (the amount of oil added to the oil conservator) + (transformer accessories - such as the amount of oil required for the radiator )Wait. The amount of oil added in parentheses is the transformer factory, and the oil drum is installed and delivered to the customer. So customers receive the transformer, the transformer should be the total amount of oil is acceptable enough

Q: How is the transformer sorted?: Commonly used transformer classification can be summarized as follows: 1, according to the number of points: 1) single-phase transformer: for single-phase load and three-phase transformer group. 2) three-phase transformer: for three-phase system of the rise and fall voltage.

Q: how to ground transformers at substations??: copper rod pounded into the ground with a wire going to the terminal that is ground on the transformer.

Q: KW how to know how much transformer?: Transformer is rated by the kilovolt, is the apparent power, know the kilowatts, with the kilowatts divided by 0.8 is KVA, should stay a certain margin, preferably 20% of the amount. for your reference.

Q: 1. If the input voltage is 100V and output voltage is 200V, which side of the transformer winding will be primary?(a) 100V side (c) winding with loss turns(b) 200V side (d) winding with more turns2. Which of the following statement about humming of transformer is true?(a) The frequency of humming tone is 100Hz(b) The frequency of humming tone is 50 Hz(c) The humming is caused by a vibration of the low voltage winding through which the high current flows(d) The humming is caused by the private force of attraction between the lamination of the core3. In a 10 KVA, 230/1000V 1-? transformer, the no load current will be around(a) 3 A(c) 10 A(b) 0.5 A (d) 0.9 A: A transformer can be used as step-up or step-down, but normally use is as step-down so b. for the first question. Second question, the humming is caused by d. and will be at the frequency of the supply. Third question would be b. or d. since the only current drawn on no-load is the magnetising current for the core.

Q: 1.) What is the function of a transformer?a.) It is a device that can change the voltage of an AC supply.b.) It can change a low voltage supply into a high voltage supply or vice versa.c.) It is a device used mainly to change AC into DC.d.) A and B are correct.2.) What is the function of a transformer at a power station?a.) To convert DC into ACb.) To produce very high voltagesc.) To produce the currents in the power linesd.) None of the above.: A transformer either steps-up or steps-down the voltage of an AC circuit at the cost or gain of current (PIV). They are used to enable electricity to travel very far distances. While a high current will also come with a reduction of power due to the resistance of the miles of wire, a low current with a high voltage will be affected very little (VIR). A transformer will convert the high current power from the power plant to low current and high voltage so that the electricity can reach further. When this high voltage reaches neighborhoods, it goes through multiple transformers to step it down to the conventional 120V power supply. Since transformers only work with alternating current, they have nothing to do with direct current. Therefore, question 1 is D and 2 is B.
