Description

The application of 334MVA/500kV single-phase OLTC auto-transformercan 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 application of the334MVA/500kV single-phase OLTC auto-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 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 334MVA/500kV single-phase OLTC auto-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: hello Im trying to ride my jet ski but the battery keeps dieing I tested my rectifier and it is getting no current at all but my stator is kicking out power so could I use a transformer to change the current from AC to DC or 20v AC to 13.5 volts DC: No. Transformers and rectifiers are completely different things. A transformer converts high voltage AC current to low voltage AC and vice versa. A rectifier converts AC current to DC at the same voltage. In your case, you need 4 new rectifiers to convert 20V AC from the alternator to 20V DC and a voltage regulator to fix the output voltage to around 13.5V DC

Q: What is the M of the transformer capacity MVA?: MVA with a table of his capacity, read: trillion volts in which M with a sign The conversion unit is 1MVA = 1000KVA = 1000000VA

Q: Does anyone have any knowledge or experience with what happens if you try to run two different power supply transformers from the same AC line input. Can you do that? I have one transformer with a primary DC resistance of 28 ohms. I have a second transformer with a primary DC resistance of 265 ohms. I want to run these two transformers from the same AC power cord input. I tried connecting their primaries in series across the AC cord input, and the resulting secondary outputs from both transformers were lower than expected for a no-load condition. I am a little concerned about trying to connect the two transformer primaries in parallel.Any ideas?: Transformers don't work with DC inputs. Transformer physics require an input that changes with respect to time. That's why they work with AC. When you apply a DC input to a transformer, it looks basically like a low resistance, depending on the size and mass of the wiring. In order to provide DC as an input to this thing you have, you need a circuit to chop the DC and turn it into AC before it is input to the transformer.

Q: As we switch off an appliance at home, the power supply is cut off.when we switch it on , the power is on.How does the transformer regulate /manage as per our requirement: A transformer simply changes one voltage to different voltage. There is some voltage change due to I*R in the transformer, but the transformer doesn't regulate the voltage.

Q: What are the technical parameters of the transformer?: C, rated current (A): transformer in the rated capacity, allowing long-term through the current. D, no load loss (kW): when the rated frequency of the rated voltage applied to the end of a winding, the other winding open when the active power. And the core silicon steel sheet performance and manufacturing process, and the applied voltage. E, no-load current (%): When the transformer in the rated voltage under the secondary side of the load, the current through a winding, generally expressed as a percentage of the rated current. F, load loss (kW): the transformer secondary winding short circuit, in a winding rated tap position into the rated current, then the power consumption of the transformer. G, the impedance voltage (%): the secondary winding of the transformer short circuit, in a winding slowly increase the voltage, when the secondary winding short-circuit current equal to the rated value, then the voltage applied once the general. As a percentage. H, the number of phases and frequency: three-phase beginning to S said, single-phase start with D said. China's national standard frequency f is 50Hz. Foreign countries have 60Hz (such as the United States).

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 was animated by an American company whom employed Japanese animators, Thundercats was made by Toei who is a Anime company but it was made for Americans.

Q: What are the ways of protecting the transformer?: First, the gas protection: to protect the transformer internal short circuit and oil surface failure. Second, differential protection, current quick-break protection: to protect the transformer winding or lead-out phase of the phase-to-phase short circuit, large ground current system grounding short circuit and winding turn short circuit. Third, over-current protection: to protect the external phase short circuit, and as a gas protection and differential protection (or current quick-break protection) backup protection. Four, zero sequence current protection: protection of large ground current system external single-phase ground short circuit. 5, overload protection: to protect the symmetrical overload, only acting on the signal. Six, over-excitation protection: to protect the transformer over-excitation does not exceed the allowable limit.

Q: Here's photos of the transformer in question. My dad pulled it put of some electronic he can't remember what and has had it sitting on the garage. Recently I've been working with high voltage and he pulled this out for me to work with just having trouble figuring it out: First of all, never assume anything! There are some standard colour codes for transformer wiring, but not all transformers conform to the standards. In practice, a manufacturer can use any colour wire for any purpose, leaving you and me and a lot of other people wondering for all time, which wire is which? The measured DC resistance does not tell you anything about the AC voltage rating of any winding. With most power transformers, if there are two solid-black wires, they are the primary. If it is tapped, or there are two primaries (such as in dual-voltage units), there will be three or more primary wires (and possibly as many as 8!). I think the side with 115V on it is probably -- mind you, this is not for certain -- nothing more than the side on which that number happened to be stamped. So of course you want to know what to do next. Considering the number of wires and the ways in which they are connected, it would seem that an experimental method will be required. The 2006 ARRL Amateur Radio Handbook (and possibly other editions) tells how to figure out what's what with transformers. I strongly recommend using the procedures described therein.

Q: First of all, try not to be bias ;). My birthday is on December 19th, exactly the release date of the Transformer Prime, which is a great tablet, one I think surpasses even the iPad 2. With Steve Jobs gone and the new quad core installed in the Prime, would the iPad 3 be likely to be better than the Prime? Should I just wait for an iPad 3 if so? Thanks :)!: First of all, don't forget that the iPad 3 hasn't been announced and it will probably be a few months, at least, before it comes out. Secondly, there are sure to be spec improvements and additional features in the iPad 3. Whether they match up to the Transformer Prime, however, is anybody's guess. Third, I think the real decision should come down to if you want the Apple environment or the Google environment. Last I checked there are more iOS apps than Android apps, and if you have a Mac, iCloud is a nice thing to keep everything in sync across devices. I personally like iOS, its interface, and the way updates are delivered (as opposed to with an Android device, updates Google produces may not coincide with a new product release or may not be available right away for your device). On the other hand Android is more open, the integration with Google Calendar and all is great, there are less restrictions on what apps are allowed in the Android store, and if you are happy with Android then there's no real reason to wait for the iPad 3.

Q: Will the 250KVA, 500KVA, 630KVA Van transformer size,: 250KVA, 500KVA, 630KVA Van transformer size, size: length 4.6m, width 2.5m, 2.4m high. 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).
