Description

The application of the 370MVA/535kV 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 the 370MVA/535kV 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 the 370MVA/535kV 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: A CD player uses two 1.5 v batteries. If you want to plug it into a 120 v outlet, what kind of transformer will you need (Step up or Step down)? What must be the ratio of the number of turns in the primary to the number of turns in the secondary?: there is not any longer something incorrect with the turns ratio; the topic is that the sq. wave has severe frequency harmonics that are no longer nicely taken care of by technique of the ferrite. extra importantly, you're turning out to be to be magnetic saturation of the ferrite. you should do a calculation, based on the meant familiar contemporary, of the magnetization of the ferrite (a wisdom sheet on the middle will help), and from which you will calculate a suitable style of familiar turns.

Q: Actually both amplifies the input voltage. A step up transformer amplifies the input voltage and a transistor also amplifies. So what is the differece????: Easy. A transistor is a semi conductor that can essentially function as an on-ff switch. On certain configurations, you can use a transistor circuit with the right driving voltages to function as an amplifier/ Where as a transformer, is an active lumped circuit element which composed of wound coils, and ferromagnetic elements as a core which steps up or down the voltage of an electrical current by mutual induction. The principles behind both are VERY different, both in function, understanding and operation. Hope I helped some :)

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: I want to know how much the current will increase. But the transformers i'm looking at VCT VT10000 - 10,000 Watts Heavy Duty Continuous Use 110V / 220V / 240V Step Up / Step Down Voltage Transformer or 15,000 Watt Step Up and Step Down Voltage TransformerI figure the whats is the total possible power and if you divide the power by the intial voltage you get the current and if you divide by the out put voltage you get the final current? but what if you input doesn't equal 15000 watts or whatever the power is?: Bascally you are right. Watts is the maximum power, and dividing that by voltage provides amps. The transformer will pass what its load is consuming. If there is not enogh source eupply for the load, the source will burn out or blow its fuse/breaker.

Q: How is the transformer sorted?: Commonly used transformer classification can be summarized as follows: 1, according to the number of points: 1) single-phase transformer: for single-phase load and three-phase transformer group. 2) three-phase transformer: for three-phase system of the rise and fall voltage.

Q: I will be living in Germany for a while and I'm trying to plug my TV in, as well as one or two other things. The 1000 transformer I have works, but whenever I plug in the power strip to plug in more things than just the tv, it will automatically blow the power in the house and I have to go flip the switch again. Other Americans I know here in Germany do not have this same problem. I need help!: Only if the power strip is also rated at 3000 volts or higher. Otherwise, definitely not.

Q: I want to make presentation about transformers, I need to know suitable definition.I also want to know the Major Components, and Protection devices.Thanks a lot: A transformer is 2 or more coupled inductors. Usually the coupling coefficient is near 1. Protection devices like fuses and breakers open the circuit when the load current is excessive. Other protection devices include thermal sensors, phase rotation sensors, loss of phase sensors, voltage monitors, etc.

Q: I have 12 x 12V 10W lamps in series would I be correct in saying I need a 230-12V 120W transformer to suit?: If 12 x 12V 10W lamps in parallel then it correct in saying that you need a 230-12V 120W transformer to suit

Q: Hi! Anything you wanna say about transformers, leave here!: Transformers are cool!!!!!!! Transformers movie freaken awesome!!!!!! Transformers Animated its OK could be better, but still OK. Also can't wait until the next Transformers movie to come out!!!!!!!!!!!

Q: How do I select a transformer connection group?: Connection group can not be arbitrarily selected, depending on the primary transformer connection group. If the higher-level transformer for the star angle, the next level on the election star angle
