Description

The application of the 40MVA/110KV generator startup/standby transformer, 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 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 40MVA/110KV generator startup/standby transformer. 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 OLTC 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 OLTCTransformer’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 40MVA/110KV generator 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 OLTC Transformer products.

Q: Transformer voltage ratio and current ratio.: On the transformer voltage ratio and current ratio formula Turn left to turn right E1 is the original coil in the electromotive force, want to U1 is the back electromotive force. E2 is the electromotive force in the secondary coil, relative to U2 is the power supply. △ Φ1 is the magnetic flux through the original coil, is through the secondary coil in the magnetic flux. R1, r2 are the primary secondary coil resistance. Turn left to turn right If not the magnetic loss △ Φ1 = △ Φ2 There is Turn left to turn right According to Ohm's Law Turn left to turn right If the wire resistance is not counted, there are Turn left to turn right If the eddy current loss of the core is not counted, the input power of the transformer is equal to the output power This is available

Q: hey Guys. I'm a big fan of Transformer movies. can't wait to see the Transformers-2. Not a real trailer has been released? :( . I would like to know which robots r going to b in the next epic battle?? :): Soundwave. Optimus Prime 3

Q: 800kw motor how much transformer: Power supply voltage is how much, the motor rated voltage is how much, 0.4KV or 6KV, or 10KV. It is the starting mode is the frequency or other, consider more factors, it is recommended to consult the motor manufacturers more reliable.

Q: i have the 240V AC to 12V AC step down transformerwhen i connecting directly to 240V line the output is higher at about 16Vi need only 12V for my circuithow to get the exact amount of output voltage?: you have a 1/20 step down transformer that is broken,you should try another trans and see what happens or try 220 witch is the reel voltage/20 maybe you get 10v if your lucky at the end

Q: Did anyone actually buy Go-bots once Transformers came out?: dude gobots sucked. they were a poor mans transfromer

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!: The odds are fairly good that the black wires are primary, the red wires are one secondary, the yellow wires are another, and the striped wire is a center-tap on one of the secondaries. There is a standard ritual for identifying the characteristics of an unknown transformer: first, use an ohmmeter to identify which wires to a single winding, and which winding has the highest resistance. Next, apply power; the safest way is to use a 40-watt (or thereabouts) light bulb in series with a 120 volt source, and connect this to the highest-resistance winding. Now measure the voltages across each winding. That will give you the turns ratios, and you can get an indication from the physical size of the device as to how much power it can handle.

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?: You have 2 problems there. 1. Voltage; 2. Frequency. In this case, both are against you. NZ has 50Hz mains frequency at 240V. If you are really lucky, the transformer will have dual windings on the primary, or a 220/240V. tap. If you don't know what you are doing, consult an electrician or electronics tech. to have them check whether it is dual voltage, and change it. The frequency difference can mean a little less efficiency, the transformer may get a little warmer in operation. But it should be fine. You only other options are to replace the transformer (get one for dual voltages?), or use a 240/110V stepdown transformer ahead of it. The stepdown transformer must have a sufficient power rating for the job.

Q: Hey!I Love Shia Labeouf I Was Wondering If Transformers Was A Good Movie I Haven't Ever Got A Chance 2 Watch It. Is It Worth Watching? These Are Some Of The Films I Like.Pirates Of The Caribbeanthe Dark KnightSpider man 3 Home Alones Mean GirlsThnxxP.S. I Heard Theres Going 2 Be A Transformers 2! D: Transformer is honestly the sickest movie of all time. Are you kidding me. I watched it at least 7 times, and I had to buy the movie when it first came out. Only movie I have ever bought, and I didn't even like transformers that much growing up.

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: Rumble and Laserbeak

Q: Photovoltaic grid-connected system, with the inverter with the role of transformer. In the choice of inverter with a transformer and without a transformer, how should choose? That is the isolation, I do not quite understand. Who knows that high! Thank you!: Inverter with a transformer is played a role in isolation, it can provide you with pure sine wave current, so that the PV grid-connected system can provide a more secure and reliable isolation.
