Description

The application of the 50MVA/220KV SF6 Bushing startup/standby transformer, 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 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 50MVA/220KV SF6 Bushing startup/standby 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 the 50MVA/220KV SF6 Bushing startup/standby 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: I have halogen lights in my basement. When i mean contact i am talking about this little hanging jack where by you plug in the light bulb into. For some reason, one of my lights are not working properly but I have already tested the light bulbs out. I have a feeling that the contact/transformer (hanging jack slot) is ineffective. Does anybody have an idea how to change these things?: Pull a light from one that you know is working and try that, also if your not using sealed bulbs don't touch the lamp. It depends on the type transformer if that is your problem, turn off the power, remove it and order the replacement part

Q: I can get 1 game and i think ive narrowed it down to bully and transformers. I need you to tell me which one i should get and why. Also you could suggest another game that is light m or teen and lower. thanks: transformer!!!

Q: can anyone pls explain to me about electronics .I mean in simple words to let me know,what does a transformer an i.c. and all that we see on an electronic board ??: TRANSFORMER: transformer is a device that transfers electrical energy from one circuit to another through inductively coupled electrical conductors. A changing current in the first circuit (the primary) creates a changing magnetic field; in turn, this magnetic field induces a changing voltage in the second circuit (the secondary). By adding a load to the secondary circuit, one can make current flow in the transformer, thus transferring energy from one circuit to the other. for details:

Q: Do stores that sells computers, printers, etc. also sell transformers: Transformers as in the action figures? You can find them at Toys R Us, Wal*Mart, or Target.

Q: Is the transformer a power supply?: Narrow power supply: refers to the other forms of energy can be converted into electrical energy devices, such as: generators, a variety of batteries; where the transformer does not belong to the power supply. Generalized power supply: refers to the ability to output electrical devices. It includes generators, various batteries; transformers; regulators; etc.; where transformers are power supplies.

Q: What is the transformer capacity ratio? Capacity than 100%.: Have not heard, you say is not the main transformer parallel run between the main transformer and the capacity and capacity of the ratio, or the meaning of such I made a change, you say is not: the transformer once measured capacity can be transferred to the secondary side or three times, such as three winding 50000KVA main transformer, 100/100/100, is the primary capacity can be all to the two Secondary use, you can also use all the three times, which is mainly and the main transformer winding, clip and so on factors

Q: I watch Terminator Salvation first, it was really good I thought. The best part of the movie, I thought, was when T-800 turns evil again and attacks John. It took both John and Kyle to beat T-800.But other than that, I didn't really enjoy Transformers 2. Neither did I make plans to watch it, and I thought they should've dropped Megatron as one of the villains again. I thought it was average.But which is the better sci-fi movie of the year? (I think Star Trek is, but that's out of the question.): Terminator Salvation

Q: I bought a Neon Sign Transformer over OKorder and for a while it worked great. I used it to power a Jacobs Ladder (I wired the transformer straight to the Jacobs ladder). However, now the transformer will turn on the jacobs ladder but after a couple of seconds it will shut off and sometimes make a buzzing noise. What is wrong with it and how can I fix it?: It sounds like your transformer is shot and your chances of repairing it are pretty low. You may have been overloading it and burnt an internal connection. Do you have access to a good ohmmeter? Check the resistance, L1 to L2 and H1 to H2, preferably when it's warm like right after it's stopped working. The high side should be several times higher than the line side. Unless you are really sure you know what you are doing don't even try to repair it. The high side is putting out 8 to 10 KV and if your repair isn't up to it you can bet it will leave a mark.

Q: What is the meaning of the transformer 'turns ratio'? what's the effect?: The number of turns of the primary coil (that is, the number of turns around the coil) and the number of secondary turns. Turns ratio and voltage ratio is proportional. For example, 220 volts to 10 volts voltage ratio is 220: 10, turns ratio should also be 220: 10, such as the primary is 2200 laps, the secondary should be 100 laps. Multi-turn ratio is the number of turns of the secondary output and the primary correspondence. A variety of turns ratio is to allow a sensor device is used for a variety of heat treatment process. I remember answering your question? how? Do not believe? 'U1 / U2 = n1 / n2' "/" Or ":" read here as "than", the size of the ratio is that you say the size of the divisor, you put it when the division can also be seen. U1 / U2 = n1 / n2 'U1 denotes the primary voltage of the transformer, U2 denotes the secondary voltage of the transformer, n1 denotes the number of primary turns of the transformer, that is, the number of turns, n2 denotes the secondary turns of the transformer, The number of turns, n1 / n2 is the turns ratio. The meaning of this formula is: transformer primary and secondary voltage ratio = its primary and secondary turns ratio (turns ratio) I do not know you can not understand, do not understand I can do nothing

Q: From the following transformer, how would I calculate:a) the equivalent impedance on the low-voltage sideb) Converting the impedance found in (a) to it's per-unit quantities: a) the turns ratio of the transformer is 20 to1 so to refer an HV side impedance to the LV side you divide it by the square of the turns ratio which in this case is 400 which gives: 0.001+j0.00025 ohms. b) There's a certain amount of freedom in doing this for you may define the per-unit impedance base however you want. It is however rather usual to define it as VA / I^2. Here I 5000/2400 2.083 amps So base impedance HV side 5000/2.83? 624 ohms making the given impedance (0.4+j0.1)/624 p.u. This p.u. value should be the same on either side of the transformer. Nice to see you around again but do I notice you haven't improved at saying please when you want someone to do something for you for nothing. If you can't learn that there's not much use in learning all these technical skills. You're going to remain a clumsy oaf!
