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: I didn't. I even watched it at I-Max with my boyfriend and a few friendslets just say I wasn't the only one falling asleep. It was long, too long. They could have cut it down by at least 30 minutes.: I didn't like the first or the second part. They both really, really sucked. I also grew up with Transformers. I remember watching the cartoon everyday and really liking it. Maybe I'm wrong or uninformed about everything, but didn't the Transformers used to fight other robots in the original cartoon? Why are they fighting people now? I don't understand. On a side note, maybe my taste has changed since then, but the idea of robots undercover as cars and trucks seems really pathetic. I don't know why I watched this movie. I guess all the hype drove me to the theatre. So in closing, no I did not like Transformers 2. The end.

Q: i went to see transformers on july 3rd. they had about 5 or 6 previews before the actual movie started. the very last preview showed and party to someone called bob. he was leaving, going to japan. then the lights went out and a big groan was let out and a earthquake happened. they all went out to the roof, and in the distance, a big orange ball was exploding, shooting out fireballs and lava. they only said it was coming out on january 18 2008, and they didn't give the name.please help, i need the name of this movie: Yeah I have the same question. I went to see Transformers and I was like what the hell? That is a movie made by the no-name brand. I do not think it is I Am Legend, thought that looks like a good movie. That name of the movie was sort of obvious. ^^

Q: Calling all fans of Transformers! I am looking for anyone to tell me if Transformers Animated is coming back for a third season on Cartoon Network. The reason why I am asking this question is because I recently bought the second season of the show and noticed that they have a lot of information on new characters as a special feature and I am wondering if those characters will be in the third season of the show.: unlikely they will not

Q: How do step up transformers obey the law of conservation of energy?: I often end up submitting the same question on other sites

Q: Hello, I am using a spark transmitting system that will throw about 40KV at about 5MA. I need to step this way down. What rating should I look for? If a current transformer isn't the way to go, please tell me what I should doThanks in advance: Current transformer coupling the 40kv line then produce about a few hundred volts depending on how many turns existed in the current transmitter. It needs many such transformers to do different step down. If you require over 5kv per step,current transformer coupling might not be the best way. The better way is control the high voltage 40kv source.Vary the supply source shall do.

Q: i have plenty of 3 phase 220 in my shop, but one of my machines requires 440 3 phase. i was going to use a 75 kva transformer with 440 primary 220 secondary in reverse to supply the machine. it is a 15 hp motor 40 amps. i figured my minimum kva requirment to be 37.5 but more cant hurt for the potential high cutting rates i may need to achieve. i simply wanted to buy the transformer, hook the 220 3 phase supply to the primary, and the output to my machine. I think this will provide me with 440 output. the motor plate says 7-1/2 hp/15- hp. 40/20 amps. Any help is welcome, i hate to buy the transformer and not have this unit work. i would change the motor wiring, but the diagram is gone, and the wires are not numbered, also i believe id have to change all the heaters, which are hard to come by, as well as various other parts in the panel. just seems the transformer is the easiest way to get this machine up and going in prouction.: The main disadvantage of using a transformer with a motor is the high starting current in the neighborhood of 600% of rated full load current. The transformer impedance will cause a significant voltage dip on the secondary of the transformer when the motor is coming up to speed. Using an oversized transformer will probably take care of that. If this is some type of cutting tool, I assume that it is never started with the cutting head in contact with the load. That will also help. Edit 1 You should also consider provisions for grounding the load side. The secondary should be wye connected so that you can ground the neutral. That means that you should buy a wye-wye transformer so that you can use the low low vlotage side as the primary and still have a wye secondary.

Q: I need to run 12 amps through a 5-ohm electromagnet which means 60 volts must fall across it. I am building a power supply bridge rectifier circuit to fit my needs. I have a transformer capable of handling the wattage requirements but I am having trouble figuring out the amount of turns on the transformer to have on both the primary and secondary. The primary will be connected to an American outlet and I just don't understand how to get 60 volts DC out since the AC RMS voltage will be different than the rectified DC voltage.: OK If you want to use a transformer, you need to step down from 120V to 60V this is a turns ratio of 2:1 the AC RMS voltage will be different than the rectified DC voltage you are getting mixed up with rms and peak voltages. the input is 120V rms. (RMS tells you the work the electricity can do) if you take 60V and full wave rectify it you get a double hump - the shape is different but the rms is the same. skillbank .uk/psu/trfrec.ht I dont know why you are worrying about the turns ratio if you already have a transformer? Alternatively: use two electromagnets in series, so the will run directly from the rectified 120V supply; OR just use a single diode to half-wave rectify the mains supply, which will give you an output of 120RMS / 2 60V RMS. The electromagnet will get hot and buzz a bit but will work fine. LG, have you tried to source 1 FARAD capacitors with a rating of 60V and ripple current of 30 AMPS? skillbank .uk/psu/ripple.ht

Q: Hello,Recently, my air conditioner broke and I hired a man to come fix the machine. Unfortunately, he did not help my situation and possibly made it worst.Initially, he informed me that my transformer was broken and so said that it needed replacement. However, when he replaced the transformer, both the transformer and the circuit board blew out. Now, he's making me pay, not only pay for his services, but also for the two additional parts. My question is: Is is possible that the circuit board caused this issue? Or did he mess up on the wiring and blow both parts out, by mistake?I just need to know, so I don't pay for something, originally not of my cause.Thank-you.: Transformers don't normally fail for no reason. In most cases, something caused the transformer to fail, so it is incumbent upon the person servicing the unit to figure that out first before installing another transformer and powering it up. If it can't be determined what caused the failure, it is best to install an in-line fuse so, if there is an issue, the fuse will blow before taking out the transformer and the circuit board. Having said that, in a lot of cases, the circuit board has its own built-in fuse to protect the board from cases such as yours, so the board fuse should have blown before the board became damaged. I don't have much confidence in what your man did, so I'm more likely to blame him for blowing out your circuit board and the new transformer, unless he can prove otherwise.

Q: I would like to get my grandchild all the transformer movie dvds but don't know the names of all of them. please help and thanks: Transformers, Transformers: Revenge of The Fallen, and Transformers: Dark of the Moon(comes out September 30). Hope I helped.

Q: Can someone tell me what the tiny transformers are. I remember that they are somehow activated using some green energy device. I'm not even sure if that is it: There have been several small transformers. Soundwave had Lazerbeak, Rumble,and Ravage in the anime. There was also the autobot version Blaster who showed up in later seasons. You also might be talking about headmasters, Brainmaster(may have only been shown in Japan), or the minicons from Transformers: Armada. There was also an episode where 3 Autobots shrunk down and entered Megatron in order to retrieve the Heart of Cybertron.
