Description

The application of the 380MVA/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 380MVA/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 380MVA/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: Transformer voltage ratio and current ratio.: On the transformer voltage ratio and current ratio formula Turn left to turn right E1 is the original coil in the electromotive force, want to U1 is the back electromotive force. E2 is the electromotive force in the secondary coil, relative to U2 is the power supply. △ Φ1 is the magnetic flux through the original coil, is through the secondary coil in the magnetic flux. R1, r2 are the primary secondary coil resistance. Turn left to turn right If not the magnetic loss △ Φ1 = △ Φ2 There is Turn left to turn right According to Ohm's Law Turn left to turn right If the wire resistance is not counted, there are Turn left to turn right If the eddy current loss of the core is not counted, the input power of the transformer is equal to the output power This is available

Q: Transformers have any way of cooling: Selection of strong air-cooled cooling mode, when the pump and fan lose power supply, the transformer can not run for a long time. Even if no load can not run for a long time. Therefore, two separate power supplies should be selected for use by the cooler. ????When the oil-water cooling method is selected, it can not be operated when the pump cooling water loses power. The power supply should select two independent power supplies.

Q: hello. I've been thinking about this long and hard. you see ever since I was 2 years old I've been collecting transformers figures and other items. now that I'm getting older I know I must let go. but its kind of hard when for the first 8 years of m life my transformers were all I had. and I know when we die we will leave these things behind. but it seems so hard to let go. so what would you do if you were in my sitiuationcause this is very hard for me and i'm lost. I know in heaven we will all be happy but it seems weird to me will I not remeber transformers?if anyone has any ideas that would be great thanks.: WHY DO YOU HAVE TO LET GO OF WHAT YOU LIKE? YOU CAN BECOME A PROFESSIONAL TRANSFORMERS COLLECTOR, AND TURN YOUR INTEREST INTO A MONEY MAKING CAREER. YOU MIGHT MAKE YOUR FIRST MILLION BY THE AGE OF 16, WHO KNOWS?! THESE PEOPLE IN HOLLYWOOD ALREADY MADE TRANSFORMERS INTO A MUITI-BILLIONS BUSINESS, SO CAN YOU! LETS HAVE FUN GET DOWN TO THE BUSINESS.

Q: I live in Market Weighton and I need to know why my local electricity transformer is. Where will I need to look?: For residential, the step down transformer for home electricity use is typically a pole top mounted transformer. It may be at the top of a power pole near your residence. Sometimes there may be a pad mount transformer (square metal box) near your home that is used. You may want to look outside your home, and see where the wires coming into your electrical service are coming from. That should tell you where the transformer is. If you live in a newer neighborhood, you may have underground service ( thus no power poles) and the transformer may not be visible. It would likely be close by in an underground electrical vault. There is a picture of a pole top transformer in the attached article below:

Q: Is the upper oil temperature of the transformer high or lower?: Of course, the upper oil temperature is high ah, the liquid convection effect ah.

Q: do you know when the knew transformers film is coming out ( the year as well): 6/24/09 in the US

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: KW how to know how much transformer?: Know the number of KW, how to calculate how much transformer is needed. In general, our calculation is based on the nature of the equipment, the production process, the development prospects of the production enterprises to analyze the size of the transformer, some companies, how many kilowatts to choose the number of KVA, and some enterprises have all the equipment must boot Run, then, on the choice of a little bigger, the machinery industry enterprises, generally in accordance with the installed capacity of 4-5 fold to select the transformer capacity. For reference only.

Q: Anyone know the name of this shoe like transformer.: There are four shoe transformers. I am assuming you are talking about the ones that look like Nike Free 7.0 Running shoes made by Takara and available in Japan. There is Convoy ( Red White and Blue), Megatron (Black and Grey), Starscream ( Maroon and Black), and Marine Convoy ( White, Blue). These are exclusive to japan. However since there is no picture, I can also assume you may have a Kids meal shoe Transformer from Subway. Good luck!
