Description

The application of the 63MVA/220KV startup/standby transformer, and matches well with the transmission capacity of UHV 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 63MVA/220KV startup/standby 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 UHV 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 UHV 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 UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of the 63MVA/220KV 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 UHV Transformer products.

Q:I am build a band pass filter but I am wondering if one of the inductors in my filter can act as a transformer at the same time. I'm assuming not since it would be sending all its magnetic energy into the secondary rather than back into the primary. Can someone confirm this for me please? Also, if it DOESN'T act as an inductor than would it be okay to put it in parallel into my filter? Or do I put it in series? Where do I put it lol?Thanks: A transformer *is* a pair of coupled inductors. A power transformer is designed to have a very high inductance on both sides and a very strong mutual inductance. A linear transformer is not designed to have high inductance, but rather to have a relatively normal value of inductance (milli-henries to micro-henries) and a similar mutual inductance. Linear transformers are often used in mixers. As to your question, usually to get inductors to act as transformers you have to get them close together, usually having the coils either intertwined or line up the cores with each other. Putting the inductors in parallel (that is, no series capacitor between them) won't make them act as a transformer, but it will lower the equivalent inductance: L' 1/(1/L1 + 1/L2)

Q:How do I choose a transformer? The: Select the transformer, you can not choose too large, can not choose too small According to the following method to select the transformer capacity. ???There is a very important data is not provided, is the load at the same time coefficient. Transformer with the actual load and equipment rated power ratio is called the transformer load factor. The concept of the load factor for the load is the probability that the load is used at the same time, also called the coefficient or the simultaneous coefficient, which is the probability of simultaneous use of the device. The total load is 300kw, but they are used at the same time there is a probability that the probability is the load factor. It is impossible to always use at the same time. Of course, you can according to the actual situation to calculate their own, power factor selected 0.80. ??With this formula, s = p * kX / cosφ Transformer capacity s = device rated power p × transformer load rate kx / power factor cosφ = (300 × kX) × 0.80 This is the transformer capacity. ???Do not know what the motor is used under the circumstances, so it can not be calculated, and only calculate the same time after the generation of the formula into the above formula. If the coefficient is 0.9, then the results of about 340 kVA, are used at the same time, that is, 375KVA, consider a certain margin and spare capacity, that can choose 400KVA. In addition to the above considerations, in particular, consider the motor starting current factor, select the transformer more reliable. As far as possible by the big do not rely on small. And the standard capacity of the transformer level 315,400,500,630KVA, 315KVA a little small, 500KVA big and no need. So choose 400kvA it

Q:If a transformer is rated for a maximum winding current of 10A, would it be permissible to operate it with 10A of input current when the secondary voltage to the load is 40V? Can you explain to me why?The information on the auto transformer plate wasInput 240V/ 50/60 cy 3HPoutput 0-240/280V 20 ampsThe parallel load resistance is 34.5 ohms: At 40 V and 10 A the VA is 400 on the secondary side. At 240 V on the primary side the current is 400/240 which is 1.66 A. If the load on the secondary side is 34.5 ohms at 40 V then the secondary current is 40/34.5 1.16 A and the the VA on the secondary side is 40 x 1.16 46.4. T he VA on the primary side then is 46.4 and the primary current is then 46.4/240 0.19 A. 3 hp is 746 x 3 Watts 2238 W and its rated current on the primary side is 2238/240 9.325 A. In other words the VA loaded on to the secondary side is the same VA (more or less) as that on the primary side.

Q:I read comments on youtube saying avatar cg looks like computer games.I liked avatar cg. transformers cg looks more real but I don't think movies always have to look more real.: AVATAR FTW!!!!!

Q:Will the installation of transformers, power supply bureau is how the charges? What basic price, and then what is the plane fee? And then the transformer capacity is not the same as the unit price is how much? How much is agriculture and business? Chengdu area: Peak valley price, one day divided into several periods. Each local price is different, the specific local electricity price can call 95598 advice

Q:When the transformer voltage is a rated voltage, the secondary voltage in the end is how to change with the load, what is the basis for the theory of the way you ask you about the inrush: When the primary voltage of the transformer is rated voltage, the secondary voltage does not decrease with the load current, but this is only the case where its rated power is not exceeded, and the magnetization will increase when the secondary current increases Paul its current output, a power beyond its maximum, the secondary current increases the voltage will drop until the fever burned. Inrush Current 1 Overview Transformer is based on the principle of electromagnetic induction made of a static electrical appliances, for the low voltage into a high voltage or high voltage into a low voltage, AC transmission and distribution system is an important electrical equipment. When the transformer is closed, it may produce a large current, this paper mainly discusses the current generation and influence.

Q:i think transformers, iron man is like just a man made siut transformers are the real deal.: If you're asking me what I think is the better filmit's Iron Manhands down! Jon Favreau did an outstanding job! What made Iron Man such a good film were the performances of all the actors involved in the production, the direction, the special FX, etc. (has there ever been a more perfect comic book adaptation?). Also, the film was more grounded in reality than Transformers. I grew up reading the comics and Favreau did an excellent job of taking the abundant source material and making a credible but wholly entertaining movie that appeals to a wide audience. The live-action Transformers moviesuwell, let's just say it disappointed. The animated film from the 80s is superior. Besides, Michael Bay is a pathetic excuse for a movie director. I can't believe he was tabbed to do Transformers in the first place and I'm not happy he's directing the sequel (Lord, why are they putting so many people in this filmI thought it was supposed to be about the Transformersthe robotswho cares about the people?!). If you grew up a Transformers fan like I didand I mean from the beginning back in the early 80s, then you would understand that Bay totally upset the Transformers mythos for his own ends. Yeah, the movie was successful, blah, blah, blahbut it failed to measure up in the minds of many old-school fansand the sequel will likely disappoint, too. As for what would win in a battle, yeah, the Transformers would likely win, though given Tony Stark's resourcefulness, I'm sure he could design something that would negatively effect them. He designed a Hulk-busting Iron Man armor in the comics. Still, we're talking different universes here and never the twain should meet. Iron Man will likely surpass Transformers in total box office receipts and given its critical endorsements (93% positive on Rotten Tomatoes) as compared to Transformers lack of positive reviews (57% Tomato meter rating -- certified rotten!), that makes Iron Man THE winner in my book.

Q:Power transformer parameters: B. Transformer efficiency: In the rated power, the transformer output power and input power ratio, called the efficiency of the transformer, that η = (P2 ÷ P1) x100% where η is the efficiency of the transformer; P1 is the input power, P2 is the output power. When the transformer output power P2 is equal to the input power P1, the efficiency η is equal to 100%, the transformer will not produce any loss, but in fact this transformer is not the transformer transmission power always produce loss, this loss is mainly copper Loss and iron loss. Copper loss is the loss caused by the transformer coil resistance.When the current through the coil resistance heat, part of the energy into heat and loss.As the coil is generally wrapped with insulated copper wire, so called copper loss. The iron loss of the transformer includes two aspects: First, the hysteresis loss, when the AC current through the transformer, through the transformer silicon steel wire magnetic field its direction and size changes, making the silicon steel sheet internal friction, release heat, Part of the energy, which is the hysteresis loss. The other is the eddy current loss, when the transformer work, the magnetic core lines through the line, and the magnetic lines perpendicular to the plane will produce induced current, because the current self-closed loop Circulation, and into a spiral, so called vortex. The presence of eddy current heat, energy consumption, this loss is called eddy current loss. Transformer efficiency and transformer power levels are closely related, usually the greater the power, loss and output power is smaller, the higher the efficiency, otherwise, the smaller the power, the lower the efficiency.

Q:Electrical Machinery, Electric Machines, 3-phase transformers: If by 3-phase bank you mean an array of two or three separate single-phase transformers, wired to handle 3-phase voltage changes, the 3-phase transformer will require less iron and copper to handle the same power.

Q:i think transformers: The simpsons by far! Transformers had too many effects,it got old after a while.
