Description

The application of the 68MVA/500kV standby transformer power plant, and matches well with the transmission capacity of UHV lines, which has wide prospect of application. Because of its large capacity and large volume, the whole transportation weight with nitrogen is about 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 68MVA/500kV standby transformer power plant. In order to make the products applicable to any UHV substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity UHV 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 UHV 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 UHV transformer 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 UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of the 68MVA/500kV standby 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 UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.

Q: Can a electrical transformer have more the 1 input, while only having 1 output so that the power is combined into the 1 output,or would multiple inputs make the power feed back onto the other inputs and overload them.: Rocky has the correct answers. Edit - since more contradictions have come in. Number 5 is definitely FALSE. The power out of a transformer is effectively the same as the power into it. If the 2ndary voltage is lower than the primary then the secondary current must be larger than the primary current ( since power voltage x current ) Check out old school power supplies - fused at 3 amp on the primary side ( input ) and 8 or amps on the output side.

Q: A small transformer used in a foundry has 550 primary turns and 20 secondary turns. Initially, the switch on the secondary side of the transformer is open, so there is no connection between the two ends of secondary coil.(a) What is the voltage difference between the two ends of the secondary coil, Vs, if a direct current potential of Vp 120 V is placed across the primary coil? (That is, the frequency of oscillation on the primary is zero.) (b) What is the voltage difference between the two ends of the secondary coil, Vs if Vp is 120 V and the frequency of oscillation on the primary is 60Hz? (c) Now equipment powered by the transformer is put into use and the switch is closed. A resistance of 14 Ω is placed between the two ends of the secondary coils. What is the current through the secondary coil? (d) What is the current through the primary side of the coil with the switch closed? Thanks so much!!: A. Zero, since dc current does not have a varying magnetis field. B. 550/120 20/ X 4.3636volts Ne /E p Ns / E s C.4.3636v / 14 .311 a. Es / R t A s D. .011 amp if the transformer is 100% efficient

Q: Can dry transformers and distribution cabinets be placed in the same room?: Yes. Dry-type transformers are usually placed in the room with a shell, low-voltage cabinet is with the dry-type transformers together. The general practice is to flush the cabinet. And then connect the transformer with the low voltage cabinet directly in the cabinet to go. Outside can not see the connection of copper.

Q: i am recently watching transformers prime and i am a big fan of all transformers but now i am confused.i generation 1 and 2 was good then they ended.does transformers cybortron trilogy a sequel to g2 or new start and then is tranformers prime a sequel to transformers fall of cybortrons?: 1) In the G1 timeline we have a sequel series made exclusively for Japanese audiences. They completely ignore the events in the American ending and go in a completely different direction. 1) Transformers: Headmasters 2) Transformers: Super-God Masterforce 3) Transformers: Victory 4) Transformers: Zone Then there's Beast Wars and Beast Machines is a sequel/prequel to the G1 series. ___________________________ 2) Transformers: Robots in Disguise (RiD) aka Transfomers: Car Robots in Japan is a complete standalone series, no relation to any other existing TF series ____________________________ 3) The Unicron Trilogy is it's own timeline that has 3 series. US - JP Armada - Micron Legend Energon - Superlink Cybertron - Galaxy Force but the 3rd series, Cybertron, was originally a self-contained series, the American version edits the dialogue to make it appear as a sequel to Armada and Energon. Also, the character Override, who is female in the US version, is male in the Japanese. In other words in Japan the first 2 are in the same continuity and the 3rd is a another reboot.

Q: i have an epcos 565-2 transformer and i want to know how much it will raise the electrical output of a standard 1.5 volt battery. i really do not know much about transformers, but i bought a motor, assuming that i would be able to do fun things with it, and i hooked it up to all the power i could(solar batteries, and numerous amounts of AA batteries) but it wouldn't spin anything that i attached to it more than probably 60 rpm. i bought a transformer to boost the power, and spin the motor much faster. the motor is graded for 3000 rpm maximum, but i just want it to be above 250. any help would be appreciated.: Transformers will only work with AC, not the DC from a battery. You will have to buy/build an inverter circuit to convert the 1.5 V to anything higher with a transformer (the transformer may become part of the inverter if it is the right kind). The other thing to think about is the power level. A 1.5 v AA battery is good for this much power: 1.5 volts * 1 Amp 1.5 Watts You might get 2 Watts out of it for a few minutes, but it can only sustain 1.5 to 2 Watts for about an hour. How much power is the motor rated for? If the motor is rated for 10 Watts, then 1, 2, 3, or even 4 AA batteries will not be enough to power the motor much above 250 RPM. There is still alot you need to know. Just for fun try a bunch of D cells in series (about 10 of them) The extra current provided by the D cells may spin the motor faster. .

Q: I can't remember the funny scenes from any the Transformers movies, especially 1 and 2.It's driving me nuts.I saw the third one just last week so I remember a couple of funny scenes, but other than that, no luck.If you can, could you please include a link to a video clip of the scene?Thanks so much! (:: I'll give you scene by scene from each movie that I can recall. I apologize for the lack of videolinks but I'll describe them as best as I can. Transformers: Bobby Bolivia (Bernie Mac) talks about his mom. Oh l love that woman if I had a rock I'd crack you in the head, b***h. Sam gets arrested and interrogated by the cops when Bumblebee runs off to communicate with the rest of the Autobots. What's this new thing they're on? Mojo? Ratchet sniffs the air when introduced to Sam and Mikaela. The boy's phermone levels suggest he wants to mate with the female. Mikaela makes Simmons take off his clothes. He has a Sector Seven t-shirt on underneath. Sam, Mikaela, Maggie, and Glen are flying to Hoover Dam. Rachel: So what did they get you for? Sam: I bought a car, and it turned out to be a giant alien robot. Who knew? Revenge of the Fallen Sam's mom and dad fooling around before their trip in front of Sam. Dad, this is not a rap video. Leo doing his funny dance while Burning Down the House is playing. Anything involving the Twins and Wheelie. Sam's mom. Oh, professor, I'd do anything for an A after eating a hash brownie (LOL! Funniest part of the movie). Simmons strips off his pants and shows he's wearing a Sector Seven cup underneath. Lennox tricks Director Galloway into parachuting off the airplane.

Q: How to build inverters using ferrite core transformers, details assemblies.: Transformers are only tangentially related to inverters. You don't need a transformer to make an inverter. At its most basic level, an inverter is just a couple of switches. This kind of simple inverter will only output a square wave with amplitude equal to the dc voltage input. To get a sine wave, you would filter the output with a capacitor and an inductor, and to change the amplitude of the wave, you would use a transformer (or alternately place a boost/buck converter before the inverter). If you're going to use both an LC filter and a transformer, you can save on parts by using the magnetizing inductance of the transformer as the inductance of the LC. This is all well and good, but it takes a lot of math and analysis to actually size all of the components. If you're really serious about this, you should find a good textbook and read up on everything.

Q: What is the role of the pebbles in the transformer base: Transformers base need a pool around the pool inside the pebbles, the role of the pool called the reservoir, that is, when there are accidents, transformer oil leakage, the pool can store oil to prevent the oil flow everywhere, the pool filled with pebbles, in order to Safe, on the one hand is to prevent oil burning. As well as for the convenience of the transformer body above, the following is better than a deep pit convenient? Transformer oil pit volume is calculated in accordance with the transformer oil, there is a certain depth.

Q: I have a transformer scavenge from a VCD player, written 25W on VCD player, so that should be the transformer's VA rating ?I also measured the transformer, it has 2 secondary. It have 11.1VAC on 1st output winding and 13.1VAC on 2nd output winding.So if I were to use into DC (rectification) and calculate for other maths, should I use the value of 11.1VAC / 13.1VAC, or their average which is roughly 12VAC ?: yes, 25VA would be the sum of the two outputs. IF they are balanced, that would be about 1 amp current output. That assumes any motors operate off the transformer. you can use either secondary separately to get two voltages (about 14v and 17v DC), or you can put then in series to get 24.2 VAC (32 VDC). You CANNOT put them in parallel without the transformer smoking. The DC voltages listed above assume a FW bridge and large capacitor filter. You can probably get about 0.7 amps DC out of the supplies. Again, that assumes the two windings have about the same current rating, ie, they use the same size wire.

Q: I have a small question concerning flyback transformers. I have run into some confusing problems when i tried testing the flyback using the High voltage power supply project: You might find whether your transformer is broken with an ohmmeter between the ultor cap and a pin by trying each with the meter set to a high ohms range, with (I think) the black meter lead connected to the ultor. If you don't see a result 1st. time around, try swapping the meter leads. If you get a result, try the 24V test there. If you don't, and using his method also fails, I think you have a dud. So far as the 9V test, I think that has a fatal flaw. A digital multimeter, or usually also an analogue one, cannot respond fast enough to a single pulse. A digital meter only samples at a certain rate, and if the voltage does not align with the sampling, you see nothing. Even if it does, I think you would only see an instantaneous reading before next sample sees nothing. Apart from that, the voltage spike will be well over 200V! The object is to sort out input direction in the primary. I would suggest you sort out the primary connections, and build the circuit. I have not looked at it, but I think if you fire it up, you will either have + HV coming from the ultor cap, or nothing. If nothing, reverse the primary. DON'T TEST IT WITH YOUR FINGERS!!!
