Description

The application of the 40MVA/110KV generator startup/standby transformer, 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 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 40MVA/110KV generator startup/standby 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 OLTC 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 OLTCTransformer’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 40MVA/110KV generator 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 OLTC Transformer products.

Q: could i connect a flyback transformer directly to an ac power supply instead of a 555?: If you mean a line frequency supply, then no. Flyback transformers require high frequency to work properly, and they'll pass massive amounts of current if fed 50/60hz.

Q: Transformer voltage ratio and current ratio.: On the transformer voltage ratio and current ratio formula Turn left to turn right E1 is the original coil in the electromotive force, want to U1 is the back electromotive force. E2 is the electromotive force in the secondary coil, relative to U2 is the power supply. △ Φ1 is the magnetic flux through the original coil, is through the secondary coil in the magnetic flux. R1, r2 are the primary secondary coil resistance. Turn left to turn right If not the magnetic loss △ Φ1 = △ Φ2 There is Turn left to turn right According to Ohm's Law Turn left to turn right If the wire resistance is not counted, there are Turn left to turn right If the eddy current loss of the core is not counted, the input power of the transformer is equal to the output power This is available

Q: i took it out. on one side of the transformer i have a black and a red im hooking those up to a battery on the other side i have five wires 2 red, 2 white, and 1 blue i dont know what these do or how to get current to them. does anyone know how to complete the circuit???: The transformer you have is specifically a low voltage AC transformer. You will need an digital multimeter to measure the resistance off the wires - 1 white + 1 red resistance in ohms. If no resistance off to the next pair. Also do a product code search. Who makes the transformer? You could do a parts search online and find out who makes it and how it should be wired. Running an AC transformer can be done with DC current - but it cannot be done through just a battery cell. Remember that natural DC current has no flow or cycle rate. Therefore it is at 0 Hz. So if you applied a battery cell to the transformer with natural DC as soon as you touch the wires you'd get voltage but that would be it. Nothing after that unless. You had pulsed DC current. Pulsed current via 555 timer is usually in the kHz range. This causes the AC transformer windings work like they are suppose to To get this to happen you must special circuits to change frequency. You can look up these plans online and find great tutorials on building plasma globes and such. Look up 555 timer high voltage power supplies. Very cheap and easy to make. I'd be careful making any kind of shocking device. Know the laws of your country first before making something that is designed to shock.

Q: Does anyone know where I can buy Transformers in Bluray? I have looked for it everywhere and can't find it and I need it for a Christmas gift.Thanks!: im not sure but i believe dreamworks to be one of the companies not supporting blu ray

Q: I have a doorbell that quit working. I don't know how to tell if it is the bell or the transformer: Yes it could be a dangerous situation. A better arrangement would be to mount the transformer on the outside of the panel box through a knockout. Better yet, mount it on a separate octagon box on the wall near the panel. Most doorbell transformers have an option to mount through a knockout on a box so that the 110 volt wires are inside the box, which is then covered with a blank plate. The doorbell wires then connect to the transformer outside of the box so there is no danger of high voltage getting into the low voltage circuit.

Q: Transformer voltage range of 10.5 ± 2 * 2.5% kV and 10.5 ± 5% kV What is the difference: Two transformers of the same voltage range, but the tap is not the same, the previous one is 5-speed regulator, select the relatively small, more adaptable. The latter is the third gear regulator, sometimes with the actual time required to have the voltage difference, mainly to see that your load is stable and unstable. These two kinds of voltage regulator for the basic price of the transformer has no effect.

Q: Hello forum,I have a question pertaining to transformers. I understand the current oscillating in a coil of wires around a toroid-type metal induces a moving magnetic field in the metal, which induces current in another set of coils on the other side, right? If I'm slightly correct, yay1) Are transformers specifically AC? Can there be DC transformers or would I have to rectify it after it's been stepped-down?2) Is the output voltage independent of the current? Let's say I have 50W, 120V stepped-up to 240V. If I change the power supply to 100W, will the voltage still be stepped up the same, while current would be twice as high? (Ideally)Thanks!: Transformers can work on dc if you oscillate the pulse. a steady dc voltage will not produce the any inducement. a simple 555 timer will work on small dc voltages. for larger voltages you could actually use an on/off switch and switch it manually very fast. High voltage oscillators are available. But rectifying is not necessary

Q: 1. 6volts going in a 12:220v transformeris the output 220v or less, formulas, computations 2. 12v going in 12:220v transformer (1 amp 220VA)core loss, copper loss, eddy current loss etc etc3. 24v going in a 12:220v transformer. is the 220v, lost of power in the input,: #1 - 107.8, assuming 6.0V into a 12.0V:220V transformer, with 98% efficiency. You can find the efficiency of the transformer, by looking at it's specifications. Most range from 98 to 99%. All this depends on the load as well, as a lightly loaded transformer has less loss that a fully loaded one. #2 - 215.6V. In order to get 1A@220V, you will need to supply #3 - 431.2V. 100% over spec, and bound to fail. I do not understand what you mean by is the 220V, lost of power in the inupt,

Q: I would like to know if its possible to create my own transformer- preferably by producing my own windings. My goal is to make an open-air transformer encased in an acrylic box. I would like it be able to withstand a 15A load at 120V. I want the windings to be 1:1 so that the power is just transferred through the magnetic field, not stepped up or stepped down.The purpose would be to power my PC through it, just because I think it would be cool to look at the box and imagine the energy transferring through the air to my screen. Obviously, it's doing that out in the street, and a thousand other places before it gets to me, but I don't get to see any of it!Any one have any suggestions? If it's way to difficult or expensive to make my own inductors, what kind of inducts would I need to buy, and how close would the need to be to each other?: Listen to Mr. Hobart's advice.

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.
