Description

The application of the 50MVA/220KV SF6 Bushing startup/standby transformer, 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 50MVA/220KV SF6 Bushing startup/standby transformer. 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 50MVA/220KV SF6 Bushing startup/standby 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 UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.

Q:everyone's been fighting about if jazz from transformers is white or black i think he's just white pretending to be black what do you guys think: jazz was originaLy voiced at cartoon by Scatman Crothers and in 2007 and 20009 movie jazz was voiced by Darius McCrary allso a black guy ! but it doesnt mean that he is a black because he is a robot and in a robots world there is no black or white race! tfwiki /wiki/Jazz_(G1)

Q:80 kilowatts of electrical appliances need much transformer?: 80 kilowatts of electrical appliances need 100kVA transformer. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q:I know that both at some point were comics made by Marvel and that Thundercats was animated by a japanese studio and Transformers had an original series in japan but was here in america first. That's the info I have but what is what? And please no guessing if you don't know please don't play favorites between american and japanese cartoons, ok?: Transformers okorder

Q:Power transformer primary current and secondary current: For three-phase transformers: Transformer rated capacity = root number 3 X Transformer rated current X Transformer rated voltage So the rated current of the transformer = rated capacity of the transformer / (root 3 X transformer rated voltage) Such as a 100kVA three-phase transformer, the primary voltage of 10kV, the secondary voltage of 0.4kV, then: Its primary current: I1 = S / (1.732XU1) = 100 / (1.732X10) = 5.77 (A) Its secondary current: 2 = S / (1.732XU2) = 100 / (1.732X0.4) = 144 (A)

Q:I have 12 x 12V 10W lamps in series would I be correct in saying I need a 230-12V 120W transformer to suit?: If the lamps are in parallel, a 230 to 12 volt transformer rated 120 watts or more is what you need. If the bulbs are in series, adding 7 more 12 volt bulbs 19 total is perhaps the best fix or you need a 230 volt to 144 volt transformer, rated 120 watts. Both transformers are likely special order items expensive. You should set your 120 watt transformer on a thick metal plate with a fan blowing on it, to reduce the probability of early failure. Better use a 200 watt, or more transformer so it will run cool. Alternately you can get an 86 volt transformer rated about 100 watts, and wire it as an auto transformer. 230 volts - 86 volt 144 volts also likely a special order item, but possibly, about 80 volts center taped, or about 90 volts center taped is stocked by someone you won't make a connection to the center tap. 90 volts will give you about 11.7 volts per bulb slightly dim, but the bulbs will have long life. 80 volts will give you about 12.5 volts brighter, whiter light, but shorter life for the bulbs. Another way to lose about 86 volts is a 150 watt incandescent bulb designed for about 120 volts. This bulb will give a rather dim light with a hint of orange, but it will extend the life of your 12 volt bulbs even if they get 13 volts each, by reducing the starting surge. A 10 ohm, 10 watt resistor can be added in series to lose 8 or 9 additional volts for either the auto transformer or 150 watt light bulb circuit. The 150 watt bulb will likely last more than 2000 hours, with the help of the 10 watt resistor. An incadescent bulb rated about 250 watts at 230 volts will possibly be a good substitute for the 150 watt bulb, but it will give dim red to orange light. Neil

Q:Altium designer DXP transformer in the same name how to change?: You can re-draw one, you can also copy the source file in the transformer to change it. As for the PROPERTIES you said in the EDIT PINS NAME option, that is only your name to the pin, help to understand. For example, a transformer with only one primary edge and one secondary side, and the same name (two points of the graphics port) are located in the top, 1,2 pin on behalf of the original side, 3,4 pin on behalf of the secondary, Or 2,4) is the same name. 1,2 PIN (PIN) name (NAME) were Pri +, Pri-; 3,4 pin were Sec +, Sec-. Obviously here pri and sec are primary and second abbreviations, namely the primary and secondary, and +, - can be understood as positive and negative, can also be understood as the same as + (or -) at both ends of the same name. Transformer with the name of the most obvious label is the graphics on the two points. You in the schematic after the change and then on the line. I am also doing this, need to change the same name. You can exchange.

Q:I understand that a 70-volt transformer is used in a commercial environment, to connect several 70-volt speakers to a 70-volt amplifier. But why does a 70-volt transformer have all of those different colored wires coming from it? What do they connect to, and what are they for? How would I connect a 70-volt transformer to an amplifier, and where I connect the cable that goes to the speakers? Please explain this to me in an easy to understand way, because I was curious about this for a long time.: The okorder

Q:I read something somewhere once about using small mains transformers as substitute speaker transformers in valve circuits.Suppose I have a 6-0-6V transformer with a 240V primary. That gives a 20:1 turns ratio. So if the secondary is putting out Vs volts at Is amps into 8 ohms, then (neglecting losses) the primary will have 20*Vs volts across it and Is/20 amps through it. But we know that Is Vs / 8; so the primary will appear to have an impedance of (20 * Vs) / (Vs / 160) 3200 3.2k ohms.Am I thinking right? Or will the presence of DC in the primary ruin everything?I'm thinking of using an ECL82 (aka 6BM8) for my first project, as that has both a triode and a pentode with separate cathodes and seems to be available still. Is this a good choice?: The primary is the one that needs the split winding, not the secondary. So you would need a 240-0-240 transformer. Possibly a transformer designed for 120 or 240 volt operation, so you can connect it as a 120-0-120 volt primary. The secondary, where the speaker is connected, would be the 6v or 12v winding. I lost my tube manual (tossed it) long ago. But from memory, I'd use 6L6s for the drivers, they should still be available, and have a lot of power. How well will this work? Don't know. give it a try. .

Q:Do you know what that show is called where there are these dinasaurs, and there are good oens, and bad ones, very similar to transformers.The dinasaurs transform into robots. Whats it called?: I don't know. Are you sure you aren't combining Extreme dinosaurs with the dinobots from Transformers? The only other cartoons I can think of staring good and bad dinosaurs are Dinosaucers and Dino-riders. Is it any of these? Around what time is it from? Edit looking at the other answers Beast wars had Dinobot on the Good side and Megatron as a dinosaur on the bad side

Q:I need a flyback transformer for some plasmatastic experiments. I know a place where someone dumped a bunch of broken TVs and computer monitors. Where should I be looking for a flyback transformer in this stuff and what can it look like?thanks: Follow the high voltage wire (that plugs into the side of the cathode ray tube) back to its location on the circuit board chassis. That donut shaped device is the flyback x-former.
