Description

The application of the 68MVA/500kV standby transformer power plant, 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 68MVA/500kV standby transformer power plant. 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 68MVA/500kV standby 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 UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.

Q: how do i work out the voltage output of the second winding on a transformer if i know the Primary voltage is 35v and the first winding has 355 windings and the second winding has 4500 how do you do this ?thanks: Assuming that the transformer is designed for a primary voltage of 35 or more, then you can simply multiply the applied primary voltage (up to the design limit) by the turns ratio and this will give you the output voltage. In this case: output voltage 35 x 4500/355 444.

Q: I'm getting a transformers game and idk which one to get. Should I get Transfermors: WFC (War for cybertron) or Transfermors Dark of the moon? Which one is better?: Out of all the transformers.WAR of CYB was the best!! Because it had no restriction to the movie But I think you should get The New one!! Looks Awesome though but will be expensive.

Q: I I am looking to buy a 208 to 480 transformer, would I simply buy a 480 to 208 and reverse the input and outputs? it's a 3 phase system and it is being supplied by an 80kW generator, then straight to an ATS to switch power from normal to emergency.: Yes, a transformer can be used to either step up or step down the voltage. The rating of a transformer is in KVA, so you can load it to the nameplate rating either way. One thing to consider though is your system ground. When you tie your generator feed back through your step up transformer and then to the ATS . The normal power source feeding your ATS is probably a 3 phase 4 wire grounded WYE system, and your step up transformer will probably have a 3 wire Delta primary. You need to be careful, especially if your ATS feeds any single phase loads. In that case, get a transformer with a WYE - WYE winding configuration. Make sure you follow the NEC code recommendations for a separately derived source.

Q: i need a 120VAC to 160VAC step-up transformer; like, not an already built converter, but a just bulk single transformer. where can i buy one?and don't say go look in OKorder, coz i've already looked and there isn't any: Need to know the current rating, or the wattage rating. also look for a 40 volt step down, as you can use the isolated 40 volts to add to the 120 volts from a simple isolation transformer to get 160 volts keep searching. One alternative is to get a 120 to 240 transformer, and remove some of the secondary turns to drop it down to 160 volts secondary. This size transformer is very common and comes in all sizes, for all current levels. another alternative is to get the 450 volts DC that I think you want in a different way. Use a tripler on a 110/110 volt isolation transformer, which gets you about 460-470 volts. Or be elaborate and use a doubler on a 110/220 transformer with a regulator to drop down the voltage. .

Q: I'm a good Transformers fan, but i've only really watched the more recent shows like armada, energon, etc. so i'm confused with some things in the new movie:1. Is Jetfire really supposed to be that old?2. Jetfire mentioned the Optimus must be the last decendent of the Primes? is Omega Prime one or no?3. When the Fallen appeared in the comic where he first showed up, did he have the same power over Megatron4. Did anyone else notice that Ratchet just showed up during the forest battle scene?5. Did Megatron transform into both the cybertronian tank and plane in the movie?6. Anyone else find the Twins insainly rascist?7. Is Wheelie supposed to be a small toy in the universe?8. Is the human changing robot really in the series or just the movie?9. Can Constructicons really morph with each other to make a giant?10. Is Starscream the one that eventually switches to the Autobots?11. Does the Decepticon attaching itself to the sattlelite have a name?Thank You for clearing things up: 4. yeah 6. no 9. apparently 10. no, it's jetfire, i think 11. his name is soundwave, and he IS the sattelite. he's the decep. communications officer.

Q: I have a standard transformer with 7 wires:2 black2 red2 yellow1 red/yellow stripedWhat connections do these wires correspond to?That is, which should connect internally to the primary coil, the secondary coil, and coil-taps (based on the number of wires, I assume that the secondary coil is tapped).I must determine this in order to connect the wires (externally) appropriately.Any help is greatly appreciated!: Pin Number Wire Color Function 1 Not Used Not Used 2 Black Ground 3 Grey Right Positive 4 Grey/Black Right Negative 5 Blue/White Amplifier Remote 6 Red 12 Volt Switched 7 Yellow 12 Volt Constant 8 White Left Positive 9 White/Black Left Negative

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?: It was pretty cool, nice trip down memory lane. Autobots and Bumble Bee and the bit when he blasts who's gonna drive you home cheesy and funny!!!

Q: I am going to see Transformers 3 today with some friends. Can someone give a detailed summary of what happens in Transformers 1 and 2 because i haven't seen them. Thanks to whoever helps.: here okorder

Q: If a power surge from a house shot back towards a transformer, would it ground the charge or bypass the transformer and harm the surrounding wires?: No, the transformer itself wouldn't ground it. I don't know if they have some kind of surge protector, by the transformer would just 'pass it on' (most likely blow a fuse if the trannie survived

Q: a lamp is connected to a secondary coil ( 80 turns) of a transformer by long leads which have a resistance of 2.5 ohms. Primary coil( 1600 turns voltage is 220v). the power input to the primary coil is 44w. 1) what is the voltage across the secondary coil2) what is the current across the secondary coil3) what is the electrical power dissipated in the lamp: Assuming perfect transformer. turns ratio 1600/80 20:1 secondary voltage is 220/20 11 volts primary current is 44/220 0.2 amps secondary current is 0.2 x 20 4 amps drop across wires is 4 x 2.5 10 volts. This assumes the 2.5 ohm number is for both leads, not each. voltage across lamp is 11v – 10v 1 volt power in lamp is 1 v x 4 a 4 watts. .
