Description

The application of the 720MVA/550kV 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 720MVA/550kV 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 720MVA/550kV 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 role of the pebbles in the transformer base: Shandong Yi River Pebble Factory ---- Transformer dedicated pebble production suppliers.

Q:What is the transformer absorption ratio (R60 / R15): ransformer absorption ratio (R60 / R15) is essentially the same as that of the shaking generator. It is a megger to measure the insulation between the transformer coil and the ground. In the measurement start time, 15 seconds to observe the insulation resistance value, 60 seconds and then observe the insulation resistance value, the observed 60 seconds of insulation resistance value in addition to 30 seconds of insulation resistance value is the transformer Absorption ratio.

Q:How is the insulation of the transformer divided?: n the oil-immersed transformers, the main insulation to oil-paper barrier insulation structure is most commonly used. The longitudinal insulation is the insulation between the parts of the same winding, such as insulation between different windings, between layers and turns.

Q:A transformer is a two coil component that uses electromagnetic induction to pass an AC signal from its input to its output.?How and why are transformers used on electric wires? What would be their purpose??Why do we hear that these transformers break at times?: D size batteries are not strong enough. It would be so much easier to go buy a solar powered electric fence charger , it does'nt cost anything to run.

Q:100kVA transformer can withstand much of the current? What is its formula?: Three-phase transformer: rated capacity S = √3 * rated voltage U (line voltage) * rated current I (line current) On the subject: S = 100KVA High pressure U1 = 10 KV I1 = S / (√3 * U1) = 5.77 A Low pressure U2 = 0.4 KV I2 = S / (√3 * U2) = 144.34 A

Q:A I have a 230V/12V, 3A step-down transformer. What will happen at primary side of transformer if I attach a 12V/5A device at secondary side? Will primary side attributes (such as voltage or current) change?: I really am not sure what will happen on the primary side. But I can tell you that whatever you are powering on the secondary side won't get enough power to work properly for very long.

Q:i went to see transformers on july 3rd. they had about 5 or 6 previews before the actual movie started. the very last preview showed and party to someone called bob. he was leaving, going to japan. then the lights went out and a big groan was let out and a earthquake happened. they all went out to the roof, and in the distance, a big orange ball was exploding, shooting out fireballs and lava. they only said it was coming out on january 18 2008, and they didn't give the name.please help, i need the name of this movie: Yeah I have the same question. I went to see Transformers and I was like what the hell? That is a movie made by the no-name brand. I do not think it is I Am Legend, thought that looks like a good movie. That name of the movie was sort of obvious. ^^

Q:Find the transformer ratio of a transformer having 350 turns on the secondary winding and 7000 turns on the primary. What RMS voltage must be applied to the primary of the transformer to develop an open-circuit secondary voltage of 63 V? if a load of 100 ohms is connected to the secondary winding what is the primary current, ignoring resistive and reactive losses in the transformer?: Primary/secondary ratio 7000/350 20/1 For 63 V on secondary: Primary volts 20 * 63 1260 V.

Q:I realize this may be super simple but i cant for the life of me figure out how to open a wall mount transformer it seems like they are snapped shut with no way to open?: I would ask you why you want to open the transformer? Are you salvaging it or are you just curious? Inside the brick as these transformers are commonly referred to, is a small electrical transformer. If your brick has AC output, that's about all you will see. If it provides a DC output, you will probably find a full-wave, bridge rectifier module in addition to the transformer. By the way, there are no user-serviceable parts inside. These bricks are considered disposable and therefore, are snapped shut, and/or ultrasonically or heat-sealed at the factory.

Q:As the title reads, Simply put: How did the original transformers series end? Aswell, how did some of the others, such as armada, energon, and cybertron end?: I don't know
