Description

The application of 278MVA/500kV single-phase double winding OLTC converter transformer 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 278MVA/500kV single-phase double winding OLTC converter transformer. 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 278MVA/500kV single-phase double winding OLTC converter 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q:I heard that a transformer is like a ratio device for amps and volts, but I know there must be more to it. How exactly does it work, and what happens when it doesn't have enough current, but enough voltage?: A transformer is a pretty simple device, it consist of two or more windings around a iron or ferret core. First keep in mind only AC works in a transformer. Transformers work by the primary winding generating a magnetic flux in the core. The second winding will pick up this flux and convert it back to voltage. Note: Michael Faraday in 1831 discovered this interaction which made transformer, motors and generators possible. Basic rule: Power in Power out - some losses. The ratio of the turns on the primary to the secondary will determine the increase. ie 10 turn on a primary and 100 turn on a secondary will step the voltage up x 10. The turns ratio control the step up or step down of the transformer. More winding on the secondary than the primary will cause a step up of voltage, Less winding will step down. The current carrying capacity of the transformer is controlled by the size of the wire. If you exceed the current carrying capacity you will burn out the winding. Heaver wire can handle more current. I know you have been interested in High Voltage step up transformers. The most voltage a transformer can produce is about 12KV. Usually after that it become extremely difficult to isolate the wires in the secondary to keep the current from jumping from one winding to another and burning out the transformer. The way to step up the voltage after the transformer is to use a voltage multiplier cascade.

Q:I am an avid stop motion animator, and I have been looking for Transformers toys to buy and animate. I have one, Deluxe Class Cliffjumper, and he's really great, pretty much the same as Deluxe Class Bumblebee. He works very well for stop motion. He transforms great, he looks cool, he's got good feet, he has stiff joints, and is very flexible and poseable. But I've been looking for another Transformer toy that can do the same job. So far I've bought two, and they have not been the same quality. I bought Deluxe Classes Barricade and Bonecrusher, but Barricade was too flimsy and Bonecrusher is too top heavy with terrible feet for poseability. Anyone familiar with the Transformers toys that could give me any ideas for the better toys for animations? (Under $40, please.) Thanks!: Do you mean the monster will say rates as he kills, or do you mean the full soundtrack would be rates. So, if he have been to have a communication, all of his communication may be sampled from different video clips? If it is the later subject, then i might propose getting Jack Nicholson video clips. His voice is so creepy and he has made maximum of flicks, you have have been given to be waiting to come across something you will need. If it is the former (the place he's in basic terms quoting type video clips), i admire: Wait'll they get a load of me! Jack in Batman right this is Johnny! Jack interior the Shining you are able to not shield the fact! Jack in some reliable adult males How a pair of superb interest of chess? the pc in conflict video games hi, Clarise.

Q:1- the properties of electrical transformers . #92;2-their uses . #92;3-their applications.: Through magnetic induction, a transformer transfers electrical energy from one circuit to another. I think it is used to step up/down the number of volts. It also allows alternating current to transmit electrical power over long distances.

Q:Transformer winding maximum temperature at?: From the heat point of view, each part of the winding are the same, the maximum temperature of the transformer winding in the worst part of the heat dissipation, generally in the middle of the inner winding.

Q:What is the power transformer, what is the rectifier transformer: Rectifier transformer is isolated transformer, is often used in the power distribution cabinet to do the power.

Q:There are lighting transformers, tires and disassembling machine transformers, there is an electromagnetic starter, the tire changer transformer will always burn ah, are used 380V transformer, I have measured the next, when the transformer transformer measurement 391V, electromagnetic Starter average is 396V, nothing to have, has been used very well. But the tire disassembly machine transformer to die, the average voltage of 396V, installed up a few seconds to very hot, but why the other two no matter? Put away Tire disassembling machine Transformer I alone load the air switch voltage ah, 396V, only more than 10 V, the other transformers are not any problems If there is no problem with the secondary side, the voltage reaches the number of volts, the transformer will quickly become hot PS: 396V I was in the 380V where no-load test ah, more than 10 volts are not ah: It is possible that the transformer is small. Look at the transformer capacity, take a look at the voltage of the voltage overload. 380v transformer connected to the 396V power supply can be used normally! No problem with the occurrence of heat may be wrong wiring, or the rated voltage is wrong.

Q:do you think transformers is cool or not and why?: Yes, Well at least the graphics, special effects, action, and the cool tight cars were awesome but they could have made it a bit better by showing more of the new robots that came in the movie.

Q:I wa watching the films and was wondering how the transformers just spawn more and more. For example soundwave made the panther thing then it made the thin robot and all those construction guys too, then they made the huge robot with the balls.: It's all science fiction.

Q:Could someone please explain, in relatively simple words, how an electrical transformer works?: You need to understand how a magnetic field interacts with coils of wire. If you know how a generator works, then it is a simple step from there to transformers since the basis for a generator's magnetic field cutting through coils of wire is essentially the same thing as how a transformer works.

Q:I mean i want to watch transformers 3, do i have to watch 1 and 2 to enjoy the film ?: Yes, Transformers: Dark of the Moon follows Transformers and Transformers: Revenge of the Fallen. I don't think the story's so complex that you won't be able to follow it, but I would recommend watching the first two films if you have the time.
