Description

The application of 32MVA/220kV main 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 32MVA/220kV main 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 32MVA/220kV main 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:even in a dc transformer, the cause varying current though not in polarity, can cause a change in the magnetic flux linked with a coil.: Transformers are used for obtaining a voltage which is different from available supply voltage. The supply voltage on the primary induces a magnetic field in the primary coil. This magnetic field is shared by the secondary coil, in which depending on the number of turns ( coils), a voltage is induced. To induce magnetic field, we need a relative movement of supply source and the medium where it is induced. In AC, since the voltage is varying in magnitude and direction, a stationary primary coil can get induced to produce a magnetic field. In DC, since there is no change in direction, voltage will not get induced in a stationary primary coil ( except during the switching transient conditions. i.e On and off times). Note that the fundamental requirement for induction is rate of change of flux.

Q:I know that a step up transformer (stabilizer) increases/decreases the voltage that is received from the main electrical lines thus allowing gadgets to work properly. Keeping this in mind will the following idea work:1.You start a motor with the help of a battery,2.The motor then turns a dynamo using a strap (connected like a chain on a bicycle) 3.The dynamo produces electricity, this electricity is sent through a step up transformer, this then increases the output of power received from the dynamo.4.This increased power is then sent to a set of plugs, where devices can be plugged in to use the increased power. One permanent plug/use will be to recharge the battery or to run the motor by using a changeover switch (battery to motor ---- output from dynamo to motor): The dynamo produces electricity, this electricity is sent through a step up transformer, this then increases the output of power received from the dynamo. No dice. You are violating the first law of thermodynamics. If you step up voltage, you step down current. Example. You step up 10 volts AC to 100 volts AC. If you draw 1 amp of current on the 100 volt secondary, you will draw 10 amps of current on the 10 volt primary, assuming 100% efficiency.

Q:chemical transformer.: to transform WHAT into WHAT?

Q:What is the meaning of auxiliary transformer, sub-variable and box change What is the difference (in addition to the capacity difference), how to work with, thank you: During the main transformer failure or overhaul, the auxiliary transformer provides the substation's own electricity. Maintenance of substation lighting, high and low voltage switch action, with the cabinet switch operation, for instrumentation and automatic control system work, sub-change can be box change,

Q:A 120-V, 60-H air conductor is to be operated in a remote area where the voltage drop in the long transmission line results in a utilization voltage of 102-V. Determine:A) the required step-up voltage ratio for the satisfactory performance.B) The voltage ratio of a standard buck-boost transformer that most closely meets the requirements of the loadC) The voltage at the load with the buck-boost transformer installedD) Sketch the appropriate connection diagram and show the NEWM standard terminal markings: I already answered this. First, what is satisfactory performance? Is the 102 volts the lowest the voltage reaches? I asked you this last time, and I still don't see an answer. If 102 is the lowest, than adding 10 volts is all you need, as that gets you 112 volts, and any 120 volt appliance will operate fine at 110 volts. A 120 to 12 volt transformer is easy to find, and with 102 volts input you will get 10 volts output, and added to 102 that gives you 112 volts, plenty to operate the AC. Parts of this question read like a homework problem, but parts don't such as the undefined term satisfactory performance, so which is it?

Q:Where is the transformer used?: Transformers are suitable for applications where the voltage level is to be changed Need to change the impedance to match the front and rear impedance of the occasion It is necessary to increase the current supply as a booster

Q:I remember a Transformers cartoon and there was like a gas in it and if the Autobots were in a place that the gas was in there, they would turn red and turn evil and fight each other. And also Optimus Prime was dead fist and then some Autobots bring him back to life And I think Rodimus has the matrix. What was that movie called?: Actually no. No knowledge of the TV series should affect you watching the movie. The story of the Autobots and the Decepticons is clearly explained in the movie. It doesn't matter is you've seen the TV shows or not. This movie is for everyone. Not everyone because there are some inappropriate terms used that you would usually hear in a high school. There is also one scene where a mother asks her son if he has been mas*****ting. It's not really a kids movie. But, despite that one scene, it's one of the best movies I've seen this summer and once again, no, you don't need to watch the TV series.

Q:I need a transformer that can produce 10 volts from a 1/2 volt change in the primary winding, but don't know how they are classified. The transformers I've seen on the internet give no clue of the winding ratio, just a serial number. Thanks.: If okorder

Q:Hi, I need a High Frequency( example~200khz) High voltage(200 000v) power supply at low microcurrent, I know that a Tesla coil fits the bill very easily . But I need to manually VARY the frequency(say from 100khz to 200khz ) while keeping the High voltage the same? Is this possible, Can some one guide me where I can buy or build this? Can I just for instance connect just a van de graaf or a rectified Tesla Coil to a function generator? If not what do I need to do to achieve what I want? I have been searching without help so your support is much appreciatedThanks: The Tesla coil needs to operate at the same resonant frequency on both the primary and secondary sides of the loosely coupled transformer. The resonant frequency is set by the inductance and capacitance of each side. The problem is there are no high voltage solid state capacitors (varactor diodes like you see in r.f. receivers that adjust the tank circuit frequency) on the primary side, and no way to adjust the top hat toroid capacitor on the secondary side (unless maybe it was a mylar covered balloon with vacuum deposited aluminum that could be remotely inflated or deflated). So you are stuck with whatever high voltage capacitor and toroid top hat you have on hand, and the inductance of the coils you wind that ends up being the resonant frequency. Even then it takes a lot of fiddling to get both in tune to give the maximum voltage output. The input frequency to the primary coil (the 555 circuit used in the step up with the flyback transformer- its frequency was chosen solely due to the flyback's frequency design) has little to do with the primary's resonant frequency; again that is set by the capacitor used and the size and number of turns of the primary coil.

Q:"A transformer ratio is 110/11, then it is" "A transformer ratio of 110 / 10.5, it is" "A transformer ratio of 121 / 10.5, it is": 110 / 11KV is a step-down transformer. 110 / 10.5KV is a step-down transformer. 121 / 10.5KV is a step-up transformer. Consider the line pressure drop, the state provides a transformer primary winding rated voltage and secondary winding rated voltage.
