Description

The application of the 370MVA/525kV single phase double winding generator transformer Power Plant.can 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 the 370MVA/525kV single phase double winding generator transformer Power Plant. 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 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 the 370MVA/525kV single phase double winding generator 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q:Power industry, Taiwan change, Taiwan, transformers in the concept of what is the difference? Also, what does the measurement point mean? First into this line, hope you brothers help.: Transformer refers to equipment; Taiwan change is installed in a place of the transformer, is specifically installed, running a transformer; Taiwan area refers to the regional range of variable power supply. Metering point is for the two sides to determine the installation of electric energy meter position, in general, the measurement point should be set at the demarcation point of property rights.

Q:I'm building a ark welder and i know they get very hot, iv seen some people in ''the internet'' submerging their transformers in transmission fluid to keep em cool under excessively heavy work loads.My question is what effects does oil have on wire insulation?And what about the transformer varnish and core insulation wads and paper?: Transformers can be submerged in oil like the oil cooled transformers.The transformer varnish, cfore and paper can withstand transformer oil. Just use a clean transformer oil.

Q:Can someone all the Transformers stuff? I mean, I see a lot of stuff about 'G1' and 'G2' and I think I heard something about their being TONS and TONS of different storylines for it.Will someone name each storyline, and what G1 and G2 is, and please tell me the official canon usage?: I'd like someone to explain these dumb Action movies to me too!!! :

Q:if the transformer converts 240v ac to 8V ac, ratio 30:1 then it should step up the voltage by the same ratio, i.e, 15V ac to 450v ac.but it's not the case !!: It will, but you have to realize that the series resistance of the primary (which is now your secondary) is getting in the way. I am going to guess that this is a very small transformer, capable of one or two VA at most. The rating is a little tricky too. A 240V-8V transformer puts out a significantly higher voltage, maybe 20-30V, with no load. It's rated at 15V because under a load, with magnetic and resistance losses, the effective turns ratio is lower. Used in reverse, the opposite problem exists, because your actual turns ratio is much higher than 30:1. Edit: If it wasn't for silly ideas a lot of inventions wouldn't have been made. The secondary probably doesn't have enough turns to provide adequate self-inductance at 240 volts. It would just act like a short and burn out. There is also a possibility that there is not enough dielectric strength between adjacent windings or the frame to prevent arcing, but most transformers are designed to withstand thousands of volts so this is less likely. If possible, I'd recommend trying lower voltages (perhaps 8V from another transformer), and measuring the current with the primary (now the secondary) open. Put a load resistor in there to start just in case. If you're drawing more than a few milliamps, don't try hooking it up to the mains.

Q:I have a nice little 120VAC to 7.5KV transformer that used to call an air purifier its home, but I'm not sure how to wire it. I have some guesses, but I want to make sure I don't burn down my house so I am hoping to verify them with the help of the yahoo answers community.: Do you have a volt/ohm meter? If you do, with the transformer unplugged from any AC source, take the ohm meter and measure the amount of resistance in the black/white AC input leads; then see if there's continuity between those wires and the long white wire coming off the same side of the transformer as the AC input leads. Then take the ohm meter and measure the resistance between the single output lead and the green wire. Also check to see if there is a meter reading between the output lead and the AC input wires. If there's readings between all transformer wires, you probable have what is called an Auto-transformer. The output is tapped from one secondary winding common to both AC input and HV output. Did you take the manufacture name and model number off the transformer and do an Internet search to see if there might be an online circuit diagram? ------------------ If all else fails, make sure that all the wires from the transformer are not accidentally touching or anything and that they are situated well apart from one another, then hook up AC voltage into the transformer. Don't attempt to measure any voltages with your meter. Most likely it will not read voltage that high. Be very careful, the voltages on that transformer can HURT YOU seriously. Do not fool with the transformer leads with AC voltage applied to it. Plug in the AC voltage and observe the transformer. If nothing starts popping and smoking, it probably functining alright. Unplug the AC from the transformer. Even if the transformer was defective and shorted out internally, all it would do is cause a circuit breaker in your house to kick off. Simple matter of disconnecting the AC from the transformer and then reseting the circuit breaker. Be careful. That thing isn't a toy, and if you don't understand what your doing, that thing will hurt you or worse.

Q:I want you guys to tell me if the movie transformers its a good movie or not? Why?Thanks, See Ya!: If you watched it as a kid, it was a great movie, it had all the elements from the cartoon, and stayed true to almost everything(they had to change Megatron, he turned into a gun) And if you never saw it before it is still a great movie, great story, great acting(with a hot Megan Fox) and tons of great action. The effects really make the scenes when they transform believable.

Q:What is the impedance voltage standard of a power transformer?: High-low 12-14%, medium-low 7-9%; buck: high - medium 12-14% High - low 22-24%, medium - low 7-9%

Q:Three-phase three-winding transformer high-pressure medium-pressure low pressure is what it means: Hello! Transformer high voltage, medium pressure, low voltage, respectively, refers to the three groups of winding (rated) voltage level. For example: 220kV voltage level of the transformer: the 220kV high voltage side, 110kV pressure side, 10kV low voltage side of the three groups of voltage levels of the composition. Depending on the needs of the manufacturer, manufacturers may also be required to produce windings for other voltage classes. Such as: by the 220kV high voltage side, 35kV in the pressure side, 10kV low voltage side of the three groups of voltage levels of the composition. 500kV voltage level of the transformer: generally by the 500kV high voltage side, 220kV medium voltage side, 35kV low voltage side of the three groups of the composition of the voltage level winding.

Q:I need to find a transformer that will convert 480 input to 240 output for a motor controller. Where can I get this type of transformer? I've only been able to find 120/240 transformers.Thanks.: This configurable from a standard NEMA transformer. Of course it needs to be rated for the power you need. The transformer will have terminals H1, H2, H3 and H4 primary and X1, X2, X3 and X4 secondary. Connect the 480v to H1 - H4 and interconnect H2 to H3. Connect the load to X1 - X4 and interconnect X2 to X3.

Q:I'm 13 and I love the Transformers movie, TF Animated and TF Armadaactually, those are the only ones I HAVE seen so farI'm just wondering where to start with attempting to watch them all? And in what order? Or, doesn't it matter? I suppose it does with G1 and 2Where on the internet can I watch them? Any recommendations?Please answer! I really want to have seen every one!: not okorder
