Description

The application of the 150MVA/345kV three phases self coupling generator interconnection transformer.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 150MVA/345kV three phases self coupling generator interconnection 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 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 150MVA/345kV three phases self coupling generator interconnection 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q:I know there was Transformers the animated series, Transformers cybertron, and Transformers energon, but were there any more?: Transformers Generation 1 (G1) Transformers Generation 2 (G2) Transformers: The Headmasters (made in Japan) Transformers Super God Masterforce (made in Japan) Transformers: Victory (made in Japan) Transformers: Zone (made in Japan as one-shot OVA) Beast Wars: Transformers* Beast Machines* Beast Wars II (Japan only) Beast Wars Neo (Japan only) Transformers Robots in Disguise (Car Robots in Japanese version)** Transformers Armada (Micron Legend in Japanese version)* Transformers Energon (Superlink in Japanese version)** Transformers Cybertron (Galaxy Force in Japanese version)* Transformers Animated** Transformers Prime * Ones I've seen and completed in English version (though I saw Beast Wars/Machines in another language). **I've seen them in English version, but dropped them after a few episodes. All others I've only heard of them. I think these are it. Hope I didn't miss anythough I think there are some old Transformers movies (I don't mean live action ones), but I don't know how many are there, as I never seen the old Transformers series.

Q:How do I choose a transformer? The: Select the transformer, you can not choose too large, can not choose too small According to the following method to select the transformer capacity. ???There is a very important data is not provided, is the load at the same time coefficient. Transformer with the actual load and equipment rated power ratio is called the transformer load factor. The concept of the load factor for the load is the probability that the load is used at the same time, also called the coefficient or the simultaneous coefficient, which is the probability of simultaneous use of the device. The total load is 300kw, but they are used at the same time there is a probability that the probability is the load factor. It is impossible to always use at the same time. Of course, you can according to the actual situation to calculate their own, power factor selected 0.80. ??With this formula, s = p * kX / cosφ Transformer capacity s = device rated power p × transformer load rate kx / power factor cosφ = (300 × kX) × 0.80 This is the transformer capacity. ???Do not know what the motor is used under the circumstances, so it can not be calculated, and only calculate the same time after the generation of the formula into the above formula. If the coefficient is 0.9, then the results of about 340 kVA, are used at the same time, that is, 375KVA, consider a certain margin and spare capacity, that can choose 400KVA. In addition to the above considerations, in particular, consider the motor starting current factor, select the transformer more reliable. As far as possible by the big do not rely on small. And the standard capacity of the transformer level 315,400,500,630KVA, 315KVA a little small, 500KVA big and no need. So choose 400kvA it

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?: Get the newer one if your looking for better gameplay, the older one is cheaper, but not as good gameplay. Hope this helps :P

Q:A transformer consists of 250 primary windings and 838 secondary windings. If the potential difference across the primary coil is 25.5V , what is the voltage across the secondary coil ? If the potential difference across the primary coil is 25.5V , what is the effective load resistance of the secondary coil if it is connected across a 135Ω resistor?: Transformer equation, N_pV_pN_sV_s V_s (N_p V_p)/N_s, plug in the numbers and calculate. N_p/N_s sqrt(Z_p/Zs)

Q:I think it will. Michael Bay who doing the movie has a history of messing up classics. Godzilla is my prime example. So, what do you think? Transformers the movie: Good or Bad?: My ONLY issue with the movie is Bernie Mac. I can't stand him. I wanted/knew Ghost Rider was gonna rock but then it turned out that it was the worst movie I've seen in 2007. I watched the trailer after seeing it realized the montage in the trailer were just boring and empty scenes but in the trailer for Transformers, it looks like they have too little time to squeeze so much (good) stuff into the movie. If you've seen the Island and liked it than you'll like Transformers as well. Trust me, Transformers won't be a dissapoint ment but it maybe considered the best summer blockbuster to the majority of Americans. (Since Pirates sucked and Spider-Man could've been better)

Q:Hello. I am setting up a 70 volt sound system. It is primarily outdoors, so I have weatherproof horn speakers. I have a 120 watt 70v amp. I also have a 70v 15 watt step down transformer. Now, I want to run 2 horns running at 15 watts rms at 8 ohms on one 15 watt step down transformer. I was wondering, is this safe? I know it works, because I have tried it. But, can it run long term and can this hurt the amp?: You should run 8 each 15 watt speakers on a 120 watt amplifier, but the system is reasonably flexible, and probably self protected, so you can connect several speakers to one of the 8 transformers. The volume on these speakers will be much reduced, but negligible effect on the other 7 transformers. Possibly the transformer with multiple speakers will over heat, but that is unlikely for ordinary music and speech. I'll guess 5 transformers with two speakers each will be ok, and all ten speakers will be the same volume. You can also connect 9 speakers in series to the 70 volt output, without using any transformers, but I understand this lowers the sound quality a little, and means no sound if there is an open circuit anywhere.

Q:I was testing a transformer I had bought, and I tested the voltage at 30v, then i proceeded to test the current, I connected both of the outputs from the secondary to a 1 ohm 25watt resistor, that is one on each side, then I connected my meter to it. I got a reading of 3.2 amps, but then it just kept falling, when I disconnected it, it had gone down to 2.75 and was still going. Does that mean I connected it wrong, I dont see how it could be wrong, but I dont understand why the current was falling. Any help?: Are you doing this all at AC? 60Hz? AC meter? With 2 ohms in the load (which is what I interpret you as doing, 2 - 1ohm resistors in series) and 30 volts that is 15 amps or 450 watts. But if you are reading only 3 amps, you are grossly overloading the transformer. And your resistors. Is the transformer rated for that much power? 450 watts? get some load resistors better suited to the rating of the transformer. Also, I note a lot of people mislabeling power supplies as transformers which they are not. .

Q:i am going to the mall and getting a target transformers pc game!anyone want to tell me about it?or anything i need to know or any cheats you can give me: i heard that game is really good on some consoles, but i didn't know that it was coming out for the PC too. any way, you get to pick which side you want to be on. its pretty cool, because when you are a transformer, you get to adventure around the city and blow things up! how much better could it get! um, so yeah,it's sopost to be an action packed game that you would probably really enjoy playing.hope you like it!

Q:What is the unit of the transformer?: Power transformer capacity unit with KVA, that is, as the power. Most of the power load is inductive load, its apparent power is equal to the sum of active power and reactive power vector. Therefore, the apparent power of the inductive load is greater than the active power. If the active power transformer, the apparent power of the inductive load is greater than the power transformer capacity, the load current to exceed the allowable value of the transformer, so the inductive load must use the apparent power transformer. If the transformer load is all the resistance load, the total power can be equal to the transformer KVA value.

Q:If a typical class 2 transformer is rated at 40 va.what is its true power rating(purely resistive load)and how is it calculated? Thx: Lots of people don't understand this rating, but it is not that difficult. The power rating of a transformer is limited by the losses in the transformer; these are core losses and wire losses. Core losses are a function of voltage and more or less fixed. Wire losses are I^2 R where I is the RMS current. Obviously, these are a function of the current squared. Now the bad news is that the VA rating of the transformer is not the same as the power rating except when the current is purely sinusoidal. This means that in case where there are rectifiers, the RMS current will be much greater than the average current, so the output power will be much less that the VA rating.
