Description

The application of 1500MVA/1000kV AC UHV Transformer can significantly improve the economy of the UHV substation, 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 470-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 1500MVA/1000kV UHV AC 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 1500MVA/1000k 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:Hi - I have some questions for any electrically minded people out there!I have a low-voltage 12v transformer, as pictured here:: That 'transformer` creates a 'separately derived system`. There should be no potential to ground. You can 'safe` the wires in the attic temporarily with 'wire-nuts`. (Conical plastic splice fittings.) If you're having trouble with the transformer look for: * Is the unit overloaded. (Any shorts/grounds in the L.V. wire.) * Is the unit adequately cooled. (There must be air flow at those vents.) * Is the 'high pot.` side connected properly?

Q:hi can anyone tell me when installing/replacing a door bell transformer when switching off power supply at main source will that make it safe to work with the connections, it keeps telling us to turn fuses off well it dont have fuses its a circuit breaker. so do we turn circuit breaker off asweel as main supply into house. may be a silly question to ask but dont wnat any trips to A nad E lol thanks guys xxx: Years ago 25+ Friedland bell transformers had two glass fuses 0.5amp,these very small glass fuses protected the transformer windings.These could be the fuses they are referring to,the main supply,as you have pointed out is fed from your circuit board. Isolate that breaker and remove the cover on your transformer and have a look for your fuses,these glass fuses are about half an inch long.Hope you are successful.

Q:Transformer is the transmission of electrical equipment: The transformer is an electrical device that converts the AC voltage level to achieve the purpose of power transmission.

Q:What is a transformer paused?: In accordance with the provisions of Article 24 of the Power Supply Business Rules: The user is suspended and must apply to the power supply company five days ago. The power supply enterprise shall handle the following provisions: 1. In each calendar year, the user may apply for all the temporary (including the high voltage motor that does not pass the receiving transformer) or part of the electricity capacity of the temporary stop power twice, each time not less than fifteen days, one year cumulative pause Not more than six months. Seasonal electricity or other users of the country, the cumulative pause time can be negotiated; 2. According to the transformer capacity of the user to charge the basic electricity, the suspension of electricity must be the whole or the whole group of capacitors to stop running. After receiving the application for suspension, the power supply enterprise shall pay the suspension of the equipment according to the date when the user applies for the suspension. From the date of the seal, according to the original billing method to reduce the corresponding capacity of the basic electricity;

Q:50KVA transformer each phase current maximum band: Hello there: - ★ 1, three-phase transformer rated output current = transformer rated capacity ÷ (voltage × follower 3). This current is apparent current, marked on the transformer nameplate. - ★ 2,50KVA transformer, each rated output current = 50KVA ÷ (400V × 1.732), equal to about 72A. Note that the secondary voltage of the power transformer is 400V instead of 380V. - ★ 3,50 KVA transformer rated current per phase is about 72A, "the maximum energy can be large" according to the ambient temperature, cooling conditions may be. Generally below the rated current, can be long-term operation.

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 know that the ratio of primary turns to secondary turns is the multiplying factor in voltage. So if you wanted 100,000 volts from a 10 volt source could you potentially do this:4 transformerseach transformer has 10 coils in primary and 100 in secondaryThe output of each transformer's secondary is connected to the primary of the next transformer so that you get 10*10*10*10 or 10,000 as your multiplying factor.Would this work?or do you have to do it the hard way and wind 10 coils in the primary of a single transformer and wind 100,000 times in the secondary?: 4 transformers would work in theory. 10v ?100v ? 1000v ? 10000v There is something called volts per turn. in the first transformer, that is 1, but in the fourth it is 1000, and that high a number will never work. wikipedia: The turns per volt figure typically varies from 1 to about 4, with around 4 turns per volt common for small appliance transformers, and around 1 turn per volt used for intermittent duty fan cooled microwave oven transformers. Volts per turn is commonly used for larger transformers, distribution transformers are often limited by excessive insulation required between each turn. .

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:Hi,Should i wait for the Asus Transformer Pad Infinity, or should i buy the New iPad ?Thanks,Patrick: Transformer Pad Infinity. The new iPAD is exactally like the iPAD 2. Dont let them fool you with the X after the A5 on the processor. Technically its the same. The Transformer Pad Infinity is the first Quadcore tablet in the market with the targea 3 and quite frankly thats reason enough to bypass the New iPAD anyday.

Q:What is the transformer absorption ratio (R60 / R15): ransformer absorption ratio (R60 / R15) is essentially the same as that of the shaking generator. It is a megger to measure the insulation between the transformer coil and the ground. In the measurement start time, 15 seconds to observe the insulation resistance value, 60 seconds and then observe the insulation resistance value, the observed 60 seconds of insulation resistance value in addition to 30 seconds of insulation resistance value is the transformer Absorption ratio.
