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:anyone else see the trailor for this movielooks kinda goodthough, it may be were the transformers are bad guys, i dunno: I saw the preview when I saw the new Pirates of the Caribbean movie. It looks pretty good!

Q:I know that Cartoon Network showed a couple of commercials for season two of Transformers Animated,but when?To add,the stopped showing those commercials.like,one week after the first time the commercial aired.Did the have second thoughts and decided to cancel it?: Transformers Animated has been cancelled after the end of Season 3. This was announced at BotCon approximately two weeks ago. Currently, there has been no announcement as to what will follow it in the Transformers TV line, other than that there will be something.

Q:A step up transformer has 5,000 turns in the secondary coil and 200 turns in the primary coil. The primary is supplied with alternating current with an effective voltage of 900V. (A) What is the voltage in the secondary coil? (B) If the current in the secondary coil is 20A, what current flows in the primary coil? (C) What power is developed in the primary coil? (D) What power is developed in the secondary coil?: a) (5,000/200) x 900V 22,500V. (5,000/200) 25:1. b) (20 x 25) 500A. c) (900 x 500) 450,000W. (22,500 x 20) 450,000W. (450KW). Both must be the same, if no losses.

Q:come on.the battle scenes and all the transformers were totally awesomebut.all the small jokes that sam and his parents and other various characters madejust killed itlike they were actually trying to add a comic element to it.and what is with the transformers cussing? it doesnt feel righttransformers dont cuss.lol: I haven't seen it, but I heard it was worse than the first one.

Q:Hi. I love the music from the movie Transformers, but none of its in the soundtrack I like the theatrical music played throughout the movie. Its all instrumental and there are no words, very good stuff. I thought it might be Hanz Zimmer who did it but I cant find out if it is him or not and how to get the music. The soundtrack bellow is not the one im looking for.1. What I've Done - Linkin Park2. Doomsday Clock - Smashing Pumpkins3. This Moment - Disturbed4. Before It's Too Late (Sam And Mikaela's Theme) - Goo Goo Dolls5. Pretty Handsome Alukward - The Used6. Passion's Killing Floor - HIM7. What's It Feel Like To Be A Ghost? - Taking Back Sunday8. Second To None - Styles Of Beyond Featuring Mike Shinoda9. End Of The World - Armor For Sleep10. Retina And The Sky - Idiot Pilot11. Technical Difficulties - Julien-K12. Transformers Theme - MuteMath Just the instrumental work done in the movie. If u know who or where I can or might get it, I greatly appreciate it.: i detect that lots of the time I do savor the songs/albums I finally end up loving maximum on the commencing up pay attention, just to no longer the full quantity. those that should advance on me thoroughly are not as undemanding. The songs i'm maximum accustomed to are classic rock radio standards i've got been listening to because of the fact in the past i can submit to in suggestions. i've got listened to them maximum of cases without getting unwell of them. whether i'm previous the degree of being obsessed on those songs, I nevertheless discover those songs the main common to savor. Being very accustomed to a music makes it like a convenience nutrition and quite enables my appreciation of it. even although, i would not say I inevitably choose that familiarity to get exhilaration from some thing. Familiarity purely has a tendency to weed out the catchy songs that lack actual substance. i've got no longer at as quickly as theory approximately this in the past, so I make an apology for that jumble. BQ: Coda- Led Zeppelin BQ2: scent the Magic- L7

Q:I have 13 lights with 12 volts 35 Watts on each light for each tree, the outlet is 120 volts current now. Should I buy 300Watt or 600Watt low volts transformer to supply all lights? Need your advise!: 600 W.

Q:Power transformer parameters: First, the transformer technical parameters The main technical parameters of the power transformer are: rated power, rated voltage and voltage ratio, rated frequency, operating temperature class, temperature rise, voltage adjustment Rate, insulation performance and moisture resistance, the main technical parameters for the general low-frequency transformer parameters are: transformer ratio, frequency characteristics, nonlinear distortion, magnetic shielding and electrostatic shielding, efficiency and so on. A. Voltage ratio: Transformer two sets of coil turns are N1 and N2, N1 for the primary, N2 for the secondary. In the primary coil plus an AC voltage, the secondary coil will produce both ends of the induced electromotive force. When N2> N1, its induction The electromotive force is higher than the primary voltage. This transformer is called a step-up transformer: when N2 <N1, its induced electromotive force is lower than the primary voltage, which is called a descending transformer. Primary secondary voltage and coil The number of the following relationship: where n is called the voltage ratio (turns ratio). When n <1, then N1> N2, V1> V2, the transformer is a step-down transformer.

Q:If load loss of a transformer at full load is 100kW, the load loss at 50% load will be a) 50kW b) 75kW c) 25kW d) 100kW. i think its 25kW because load loss is inversely proportional to the square of loading percent. kindly explain . is it right.: I'm guessing load loss is the same as copper loss, which is due to the resistance of the wire in the transformer. This loss is (I^2)(R wire) so the answer is c) 25 KW The current is 50% at 50% load, I^2 0.25

Q:10 (6) /0.4kv three-phase transformer what does it mean: Three-phase five-column core transformer must be used YN, yn0, yn0 connection, in the transformer must be connected into the angular connection of the fourth winding, it is not out of the beginning (the structure to do the electrical test when the lead is not This case). 5). When the transformer of different connection group is running in parallel, the general rule is that the connection group label must be the same. 6). When the distribution transformer is used in the multi-mine area, the Yzn11 connection method can be used. When the z-connection method is adopted, the impedance voltage algorithm is different from the Yyn0 connection method, and the copper consumption of the z-way winding is more. Yzn11 connection distribution transformer lightning protection performance is better. 7). Three-phase transformer with four volumes when the core frame can not be used YNy0 connection. 8). These are used for the domestic transformer connection, such as the export should be required to supply the appropriate connection and connection group label. 9). Generally in the high-voltage winding are connected with the tap-changer. Therefore, when selecting the on-load tap-changer (including the on-load tap-changer and the off-circuit tap-changer), it must be noted that the transformer connection and the on-load tap-changer (including connection, test voltage, rated current, Level voltage, voltage range, etc.). YN connected to the on-load tap-changer used on-load tap-changer, it is also important to note that the midpoint must be able to lead. ?The answer is recommended by the questioner

Q:Power transformer primary current and secondary current: Do not know what the specific content of the question you ask? If the relationship between the variable and the ratio, then the secondary current and primary current ratio of the transformer for a second and second turns ratio, the need for specific problems.
