Description

The application of the 270MVA/525kV single phase 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 270MVA/525kV single phase 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 270MVA/525kV single phase 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:I like to construct an autotransformer . Input voltage .240Vsingle phase. to use in a system whose operation voltage is 120v. 15 amps 1000 watts can some suggest me as to how i should proceed in calculating size of core ,winding turns, wire sizes etc , now i have 4 inches square E type transformer core . I removed all windings from it. It was used in a microwave .: You are very much over-complicating the problem. All you need is to get an 18-volt transformer and design a 15 volt voltage regulator circuit based on it. Radio Shack has lots of books, parts, and resources to get you going. Also, check your local public or college library for electronics books. Have fun!

Q:I have an old xray machine with a large step down transformer.Its not shorted but the paper insulation looks to dry. Is there a special oil for this? Thanks.: The manufacture of the transformer would have provided environmental protection. There are many ways to provide protection but most involve large pressure cookers that are designed to apply high pressure to the transformer will drying. Various waxes and epoxies are used and the pressure makes certain the sealer is driven into the transformers windings, then allowed to set. As far as I know, except for certain types of large transformers where the entire transformer is installed in a bath, oil is not used.

Q:80 kilowatts of electrical appliances need much transformer?: 80 kilowatts of electrical appliances need 100kVA transformer. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q:Transformer stop power operation, the neutral point must be grounded: A measure taken to prevent overvoltage damage from being turned off the transformer. For the high voltage side of the power supply of the power transformer, when the circuit breaker is not full phase pull, if the neutral point is not grounded the following hazards: 1 transformer power side of the neutral point to ground voltage up to phase voltage, which may be damaged Transformer Insulation 2 Transformer between the high and low voltage winding capacitor, this capacitor will cause the high voltage to the low voltage "overvoltage" 3 When the transformer between the high and low voltage winding capacitive coupling, the low side voltage will reach the resonance conditions, may There is resonance over voltage, damage insulation.

Q:I love the Transformers movies and games to death, but I've never ever been able to like the cartoons.I know they were somewhat popular, especially as the first Transformers game was a huge successplease add why you like/dislike it.thanks in advance: I loved the original Transformers' cartoon. Optimus Prime was the ultimate good guy and Megatron the paramount bad guy. No matter the odds the Autobots never gave up. Some of the coolest characters were Autobots and Decepticons. The Dinobots were just freaking cool and I always like Soundwave. The only reason the movies even had a chance of success was that they brought back the original voice of Optimus Prime. Optimus dying was a shock to be sure, but they still did a good job without him for awhile. I have happily introduced my son and daughter to the original series and they both liked it more than the new movies. It is okay you don't like the original cartoons. They aren't everyone's cup of tea.

Q:Sichuan transformer manufacturer that a best?: Personal point of view: Sichuan transformer manufacturers are the quality of the general! The scale of the larger Chengdu Double Star Transformer Co., Ltd., Chengdu, Xi'an Electric Electric Co., Ltd. to the limited liability company

Q:I know there was Transformers the animated series, Transformers cybertron, and Transformers energon, but were there any more?: Transformers Generation 1 (G1) Transformers Generation 2 (G2) Transformers: The Headmasters (made in Japan) Transformers Super God Masterforce (made in Japan) Transformers: Victory (made in Japan) Transformers: Zone (made in Japan as one-shot OVA) Beast Wars: Transformers* Beast Machines* Beast Wars II (Japan only) Beast Wars Neo (Japan only) Transformers Robots in Disguise (Car Robots in Japanese version)** Transformers Armada (Micron Legend in Japanese version)* Transformers Energon (Superlink in Japanese version)** Transformers Cybertron (Galaxy Force in Japanese version)* Transformers Animated** Transformers Prime * Ones I've seen and completed in English version (though I saw Beast Wars/Machines in another language). **I've seen them in English version, but dropped them after a few episodes. All others I've only heard of them. I think these are it. Hope I didn't miss anythough I think there are some old Transformers movies (I don't mean live action ones), but I don't know how many are there, as I never seen the old Transformers series.

Q:around the house. Im looking for a step up transformer to handle 1.5VAC-18VAC with a ratio of 1:10 or 1:20. Which household objects would contain this??: The voltage makes no difference to the transformer but only current the ratio. There are buck boost transfromers that can be bought with only a few dollars that will give you the AC voltage you want. The schemetic is difficult to read with a buck boost transformer but if you know basic electronics then it will be a snap after you sat and thought about it.

Q:Do you think transformers is a good movie?Whos your favourite team autobots or decepticons?Whos your favourite transformer?And whats the best scene in the film?: Not bad.My brother is intersted in it very much.

Q:If I have a step down transformer, the voltage in the second coil decreases. From conservation of energy (Power of firstpower of second coil) the powers are equal. But if PU*I and the voltage decreases, does the second coil have a higher current in order to maintain its power?: A transformer makes use of Faraday's law and the ferromagnetic properties of an iron core to efficiently raise or lower AC voltages. It of course cannot increase power so that if the voltage is raised, the current is proportionally lowered and vice versa. hyperphysics.phy-astr.gsu.edu/hba Goodbye
