Description

The application of the 360MVA/242kV three phase water cooling main transformer for hydro power station.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 360MVA/242kV three phase water cooling main transformer for hydro power station. 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 the360MVA/242kV three phase water cooling main transformer for hydro power station, 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:i have a transformer and i dont know anything about it. can someone help me with it.ps: i dont know how many turn the transformer have. dont the voltage either: You can tell roughly how much power it can handle by the size and weight. Old style power adapters (transformer types heavy), like you plug into the wall, provide 5-10 watts or so and weigh 4-10 ounces. If it is really small it would be a signal level transformer and be in the milliwatt range. The voltage is somewhat irrelevant except to the output. Most transformers will take hundreds of volts before the insulation breaks down. What you can do is find a current limited 10VAC (or so) power source and place it on one side of the transformer. Measure the other side and you will discover the ratio. 30VAC would be a 1:3, 3.3VAC would also be 1:3 but your source would be hooked to the large winding. If you don't know much about electronics, stay away from hooking anything to a wall outlet, the current there is a couple hundred times a lethal dose. Keep your mistakes to letting the smoke out a a few low cost devices. A small wall outlet transformer is a safe way to experiment as the line voltage is isolated and all the shock you can get is limited to the secondary or output of the transformer.

Q:If the primary circuit of a transformer is connected to a power source and the secondary circuit has a light bulb, will the light bulb turn on and stay on when the power source is turned on? Or will it turn on for a few seconds and then turn off?This question's been bugging me because I think because transformers are usually wired through AC that the bulb would only turn on for a few seconds and then turn off, but then shouldn't current be constantly flowing so it would stay on?Thanks for and clarifications.: Umm, is the power source AC or DC? You are right, transformers usually use AC. Is it not using AC in this example? You didn't say. If it's using AC, the light bulb will stay on. The current actually switches on and off, but so fast you don't see it. Well, normally, for household 60Hz AC power. But who knows with this mystery power source. It could be 1Hz AC. If it's using DC, then it will come on for a short time (a few seconds? I don't know). Yes, current is continually flowing through the primary circuit, but after a while no current will be flowing through the secondary circuit where the light bulb is connected. It takes change in current in the primary circuit to induce a current in the secondary circuit.

Q:Does the production transformer require 3C certification? Does the country have any specific requirements?: 1, depends on what you produce the transformer. If it is civil to three C certification. 2, industrial transformer is the most important to the ISO9001 quality management system certification. In addition, for different products, where sold, and another certification. 3, there are special users require certification, such as nuclear power plants with the transformer. 4, anyway, your business to have a special department, to deal with a variety of different certification.

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?: They are glued, or even sonically welded. They are made to be replaced not repaired. They can be open by sawing a knotch in the corner and prying open with a screwdriver.

Q:Actually both amplifies the input voltage. A step up transformer amplifies the input voltage and a transistor also amplifies. So what is the differece????: Transistor Transformer

Q:LED non-isolated drive transformer (two windings) calculation method: T cycle, f frequency D minimum duty cycle Vout output voltage Vin input voltage Ton magnetizing time

Q:630kva dry-type transformer rated current is how much: If it is a 10kV transformer, Then the rated current = 630 / 10.5 / √3 = 34.64A, which refers to a current, phase current

Q:Photovoltaic grid-connected system, with the inverter with the role of transformer. In the choice of inverter with a transformer and without a transformer, how should choose? That is the isolation, I do not quite understand. Who knows that high! Thank you!: Inverter with a transformer is played a role in isolation, it can provide you with pure sine wave current, so that the PV grid-connected system can provide a more secure and reliable isolation.

Q:Hey!I Love Shia Labeouf I Was Wondering If Transformers Was A Good Movie I Haven't Ever Got A Chance 2 Watch It. Is It Worth Watching? These Are Some Of The Films I Like.Pirates Of The Caribbeanthe Dark KnightSpider man 3 Home Alones Mean GirlsThnxxP.S. I Heard Theres Going 2 Be A Transformers 2! D: Transformer is honestly the sickest movie of all time. Are you kidding me. I watched it at least 7 times, and I had to buy the movie when it first came out. Only movie I have ever bought, and I didn't even like transformers that much growing up.

Q:i have this audio transformer (about the size of a bottle cap) with three prongs on one side and two on the other. i am completely mystified by this configuration. how would i (say for example) hook up this transformer to a 9v battery in order to increase voltage? thx: 9v battery has a D.C. and a transformer only work in A.C. circuits.
