Description

The application of 334MVA/500kV single-phase OLTC auto-transformercan 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 application of the334MVA/500kV single-phase OLTC auto-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 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 334MVA/500kV single-phase OLTC auto-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 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:Which transformers belong to special transformers: Transformers are generally used for AC voltage conversion if used for other purposes such as changing the frequency of the power supply, rectifying the power supply of the equipment, the power supply of the welding equipment, the electric power of the furnace or the voltage transformer, the current transformer. These special-purpose transformers are known as special transformers. Because of the working conditions and load conditions of these transformers, they can not be calculated by the general transformer calculation method.

Q:50KVA transformer each phase current maximum band: Normal current does not exceed 72A per phase current. Of course, in the event of an accident or to strengthen the transformer cooling can be short-term overload operation.

Q:Audio output transformer: If you don't want to buy one then rent it. There are a lot of electrical and electronics shops online that offer such service.

Q:I enjoyed both of these titles' first games very much. I am a big Transformers fan but I also love the first person shooting action Borderlands has to offer. I only have enough money to pre-order one and get it on its release date but I can't decide. What are your opinions? What will I get better gameplay value out of? Which do you think has a better pre-order bonus? I welcome any and all opinions and answers!: i love transformers also, i have borderlands one and the first transformers, get border lands because it is harder to beat and you can make as many charecters as you want and it has a longer story, youll get more for qwhat you pay for if you buy borderlands 2

Q:even though the output voltage of a transformer can be much larger than the input voltage, the power output is nearly the same as the power input.Determine the relationship between the input and output current and the number of turns in the input and output coils.help!!!!!!!!thank you: just read your text book. lets say we have a transformer with a turns ratio of 10:1 If we apply 20 V on the high voltage side, (the side with the higher turns ratio aka 10:1), on the other side it will have 2 V. This is because of the turns ratio. Lets say that the power input on the high V side is 100W. So the current on the high V side is 100W/20V5 A Assuming ideal transformer with no losses, power in is power out. So on the other side, you will also get 100W. So the current on the low V side is 100W/250 A Basically, going from one side to the other, the V increases and the I decreases to keep the same power on both sides, as according to the turns ratio. I hope that you can figure out how the turns ratio of 10:1 made sense here. I better get best answer for this, lol. But seriously, read the text book, see how the turns are wound see how the electric field makes a magnetic field, which makes the electric field, etc.

Q:A single phase transformer operates from a 230V supply. The primary and secondary resistances are 0.03 Ω and 1.12Ω respectively while the corresponding leakage reactances are 0.1Ω and 6.4Ω; the magnetising branch can be neglected. The secondary winding has four times as many turns as the primary. Calculate :i) The equivalent impedance referred to the primary circuitii) The secondary terminal voltage when the load has a resistance of 200Ω and an inductive reactance of 100Ω.iii) The secondary terminal voltage when the load has a resistance of 200Ω and a capacitive reactance of 100Ω.Can someone show me how to tackle this question please?: i) the secondary transformer impedance is 1.12 + j6.4Ω. Since Ns/Np 4, this impedance reflected to the input is (1.12 +j6.4Ω)/(Np/Ns)? 007 + j0.4Ω ii) Reflect the primary transformer voltage and impedance to the secondary side. 230(Ns/Np) (1.12Ω + j6.4Ω + (Ns/Np)?(0.03Ω + j0.1Ω ) +200Ω + j100Ω )I 920 (1.6 +200 + j8 +j100)I (201.6 + j108)I |Z| 228.7Ω √(201.6? + 108?) at angle of inverse tan (108/201.6) 28.18° I 4.02 amps at -28.18° 3.54 - j1.90 amps The terminal voltage is 920 - (1.6Ω +j8Ω)(3.54 - j1.90 amps) iii) solve 920 (1.6Ω +200Ω + j8Ω - j100Ω)I (201.6Ω - j92Ω)I The terminal voltage is 920 - (1.6Ω + j8Ω)I

Q:Rectifier and rectifier transformer: 1) rectifier transformer is the rectifier device power transformer. Rectifier equipment is characterized by the original input current, and vice president through the rectifier output after the original DC. Converter is rectifier, countercurrent and frequency conversion of the three working methods in general, rectification is one of the most widely used. Transformer used as rectifier power supply is called rectifier transformer. Industrial rectifier DC power supply is mostly by the AC power grid through the rectifier transformer and rectifier equipment and get. The application of rectification change the most chemical industry. Simply talk about the industrial high-power DC power supply. Civil rectifier transformers are commonly referred to as power adapters, transformers, power converters. 2) rectifier (English: rectifier) ??is the exchange of alternating current into direct current devices, can be used for power supply devices and detect radio signals. Rectifier can be vacuum tube, ignition tube, semiconductor diodes, SCR, mercury arc and so on. Generally do not contain voltage transformers. Refers to a wider range. Basically most of the electronic products are in use. 3) folk often put the ballast as "rectifier", inductance ballast is a core inductance coil, rectifier is a rectifier device.

Q:I am curious. These were popular '80s kids' cartoons. Referencing these cartoons in shows like Family Guy and Robot Chicken doesn't mean they are still popular. Are they still popular? In '03 they tried revamping He-Man in a new series but that didn't last long. They still show the classic Transformers and G. I. Joe cartoons on the Hub. They had some new toons based on G.I. Joe and Transformers and a few movies.: Yes. Transformers and G.I Joe is Still running through the Veins of this Generation, But He-Man is Kind of Not So Popular They Don't even Show He-man TV Show in channels, He-Mans drop was his costume that Gave him a Gay look. Transformers and G.I.Joe is still being watched, So there are more than 4k Fans

Q:How does a transformer effect amplitude modulation in an am transmitter. i would really love this to be explained from the basics as i am not so advanced in electronics. but i would really like to comprehend how this happens form the basics. thank you: The collector of the output transistor or plate of the output vacuum tube in a high power AM transmitter has DC voltage and an audio signal applied to it. The audio signal causes the the transistor/ tube to create AM. The AM radio frequency is shunted off to a tank circuit and then coupled to the antenna. A transformer is used to couple the audio signal to the transistor's collector/ tube's plate. A high power audio signal is applied to the primary side of a transformer and the secondary of the transformer is connected in series to the DC power source to the output device. This creates a varying DC voltage to the output device which creates Amplitude Modulation.
