 Description

 

The application of 278MVA/500kV single-phase double winding OLTC converter transformer 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 278MVA/500kV single-phase double winding OLTC converter transformer. 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 278MVA/500kV single-phase double winding OLTC converter transformer, 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:does anybody know what Transformers 2: Revenge of the Fallen is going to be about? Like what is the whole plot, or storyline?
I think its again about the cube
Q:I am installing a humidifier. It comes with a 120vac to 24vac transformer to be installed. The transformer has a label on it that says install in electrical box only. One side of the transformer is designed to screw into an electrical box knockout and has leads coming through the middle of this for connection to the 120VAC input.Is the transformer supposed to be screwed into the electrical box on the outside or the inside. At first, I assumed inside but this would result in my connection leads being on the outside. ThanksBill
Your furnace has a tranformer already and may be big enough to power the motor without installing a new one. If not install it next to the existing one behind the panel of the furnace. Or you can buy the proper size box with knock outs for everything to fit. Older homes have them screwed to floor joist and other ways. Be safe and turn the furnace power off before working or pulling the panel.
Q:I broke a small transformer that I found inside of my DVD player, and I would like to have one (not for the DVD player, just separately) I would like the transformer to take in low voltage, such as a few AA or AAA batteries, and I want it to scale that up. Does anyone know where I can get one? If not are there any instructions on how to make an effective yet inexpensive one?Thanks in advance!
A transformer cannot step up or step down DC power. (All batteries are DC). That is part of their nature. A basic transformer is nothing more than two (or more) inductor coils in close proximity, often with a steel core to help with the magnetic fields. All inductor coils are basically a coil of conducting wire, most often copper.
Q:If you use a power transformer (120VAC to 12VDC) past its secondary amperage, will it burn up or will it just not supply sufficient power?
If you are wiring the Transformer in parallel with a battery, this MAY work. Be careful to observe POLARITY (+) and (-) this is critical. First of allthe VOLTAGE of the battery and the Transformer must be the SAME.12VDC or thereabouts. If your load (device you are hooking up) draws more Amperes (AMPS) then the Transformer will supply, the battery WILL make up the difference. The problem will come.if you let the battery get too low and the transformer has to do provide more AMPS than it is capable. You could end up burning up the Transformer OR an internal component of the Transformer. To prevent this, place a FUSE in-line with the output (+) of the Transformer that is rated at the same AMPS that the output of the Transformer AMPS. Please put ANOTHER fuse in-line with the output of the Battery/Transformer combo line that is rated just above the AMPS of your Load device. This will protect both your equipment AND the battery AND your Wiring. This has all the earmarks of a learning adventure if done safely.
Q:If you're a transformers fan, who do you think were top 10 strongest Autobots in the whole transformers universe? I mean strongest of the strongest, most brutal and powerful?lol.

Q:I read comments on youtube saying avatar cg looks like computer games.I liked avatar cg. transformers cg looks more real but I don't think movies always have to look more real.
I disagree. I think the Avatar CGI was way more realistic than Transformers. I liked Transformers too tho. But if u know anything about CGI graphics, u will know that it's harder to realistically render an object with a complex exterior (such as hair, or excessive wrinkles), than it is a smooth surfaced object (such as a metallic robot).
Q:Transformers have any way of cooling
Transformers commonly used cooling methods are the following: ??1, oil immersion (ONAN); ??2, oil-immersed air-cooled (ONAF); ??3, forced oil circulation air cooling (OFAF); ??4, forced oil circulating water cooling (OFWF); ??5, forced to guide the oil circulation air cooling (ODAF); ??6, forced to guide the oil circulating water-cooled ODWF).
Q:I have a US microscope (110v) with a built-in transformer using a 6v, 10w lamp. I want to use this with a 220 v supply. What are the specifications for the cheapest (external) transformer I can use for this purpose?
What do you accomplish by converting a 110v appliance to a 220v appliance.
Q:can the amps rate be increased by using transformer from 10amps to 120amps.
If you mean a 10 amp transformer, I hope you like the smell of burning insulation. However, you could re-wind the transformer to use one twelfth the number of secondary turns, using wire with twelve times the cross sectional area.
Q:I really want a better transformers than 4 1 was great 2 was crap 3 good 4 worst of them all
Unfortunately, there probably will be
