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:I watch Terminator Salvation first, it was really good I thought. The best part of the movie, I thought, was when T-800 turns evil again and attacks John. It took both John and Kyle to beat T-800.But other than that, I didn't really enjoy Transformers 2. Neither did I make plans to watch it, and I thought they should've dropped Megatron as one of the villains again. I thought it was average.But which is the better sci-fi movie of the year? (I think Star Trek is, but that's out of the question.): I thought Transformers was the better movie. There's a lot of history and storyline involved, but even if you don't know all of it, the movie is still very good.

Q:What is an isolated ring transformer?: Isolated ring-type transformer is mainly focused on its insulation performance, between the primary and secondary must have a double insulation, so that the isolation of its own high efficiency, effective protection of equipment safety.

Q:I want you guys to tell me if the movie transformers its a good movie or not? Why?Thanks, See Ya!: First off, I did NOT want to see it. I'm not really into cars and all that kind of stuff. But my husband rented it last night and we watched it. And I will say I was surprised. I actually REALLY enjoyed it. It has a really good storyline and some pretty good acting as well! The effects are incredible too! Overall, it was a very good and entertaining movie! You should definately watch it. You won't be disappointed

Q:Power transformer primary current and secondary current: Once refers to the power side, the second refers to the load side

Q:Before engaging any technician i want to gather some knowledge about planer transformer. It will be good if u have any suggestions.: In the planar transformers, the winding is done on flat conductive guide line of printed-circuit board printed circuit board or directly the copper mooring. Flat geometry reduce loss of skin effect when switching frequency is high, that is the eddy current loss. Therefore, effectively use the surface conductivity of copper conductor, much higher efficiency than conventional transformers. A profile map of flat transformer, and make use of the different distance between two windings, to obtained leakage inductance and impedance values under the different gap 5vdc 1a adapter.

Q:i have one transformer, but i don't know what wattage does he haveso can someone help me with that: If the transformer has both the voltage and the current or amps listed on it just multiply the two to get wattage. A 110 volt transformer at 5 amps will be 550 watts. If the transformer doesn't list both of these specs, try looking up the brand and part number to see if you can find them. That would be the only way. A bigger transformer will generally have a higher wattage rating but you won't know exactly what the rating is.

Q:I have been reading about pulse transformers and i am curious if there exists a pulse transformer that would take 1 pulse/second or even less and convert to very low voltage high current. If not, would it be possible to make one? Any info is very appreciated! Thx!: Pulse transformers can be wound to any turns ratio that is desired. That being said pulse transformers have small cores and therefore handle small amounts of power. You can find cores on those old mother boards that are no longer in service and junk computer power supplies also have a couple of cores. These toroids were normally used as filter inductors to remove spikes from DC or low frequency lines. You can easily rewind them for pulse transformers.

Q:What are the serious consequences of transformer circulation?: Two parallel transformer transformer ratio is not equal, the two transformers due to the same phase between the phase difference generated by the circulation, the size of the flow of two transformers to determine the size of the difference, according to the magnetic potential balance, although the two transformers Side of the same power supply, but due to the secondary side of the pressure cycle, two transformers will also produce a circulation at the same time.

Q:current of the battery , but not through the output of the transformer but between the input and the battery, why is that?: The input winding coil is acting like an inductor. You will get a momentary surge that can show a high voltage. Without AC nothing exciting will happen on the transformer secondary.

Q:im building a step up transformer and im wondering if a 10:130 turn ratio would give me the same results a 100:1300 turn ratio. my specific questions are:1) Would i get the same power boost?2) If not, would it be similar or close to it?3) If not, why not?: They are the same at a superficial level. But they differ in the volts per turn (I don't know what the voltages are, so I can't comment further), and transformers work best with the correct value for that parameter. It depends on the core, the material, the wire size, lots of factors, and usually involves some trial and error. wikipedia:
