Description

The application of the 360MVA/500kV three-phase self coupling OLTC interconnecting 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 360MVA/500kV three-phase self coupling OLTC interconnecting 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 360MVA/500kV three-phase self coupling OLTC interconnecting 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: A CD player uses two 1.5 v batteries. If you want to plug it into a 120 v outlet, what kind of transformer will you need (Step up or Step down)? What must be the ratio of the number of turns in the primary to the number of turns in the secondary?: Do nopt worry about transformer.just buy a charger for the CD player, it's much more than a transformer and is necessary and sufficient.

Q: i have been looking at transformers and i wanted to know a few things. will they do dc current? do they just add x amount of volts or do they multiply by x or just change to x? also there is a sort of container that goes around them is that carbon???? it goes all the way around and then through: the average transformer you see on a power line, is takin a higher voltage and is distrubing down to what your house can handle which is usually 200amps. A transformer is nothing more than copper coils wrapped around carbon metal. And on the side of the transformer there is a voltage input and output tag. Transformer are huge and small. I work with them everyday.

Q: i just obtained a transformer from a small ac-dc converter. usually, it converts the 240v ac (let's call it terminals a and c) to 4.5v dc (terminals d and c).what if i connect a 4.5 dc supply to the terminals d and c? meaning that where i would usually obtain the converted electricty, instead, i connect a 4.5 to it, leaving the terminals where i would usually connect to the wall empty. wouldn't the magnetic field step up to 240v?: Nope. Not at all. (Note: this only applies to transformers, not to modern DC-DC switch-mode converters that are used in power bricks and cell-phone chargers -- those usually won't work in reverse either, but that's another story) Transformers only work for AC. When you put DC into a transformer, you get nothing out on the other end. Assuming your converter uses a transformer, it probably consists of the transformer and a diode rectifier. If you try to put DC through the rectifier in reverse, it will block it. If you rip out the rectifier and put DC through the transformer, it will get very hot, but you won't get any voltage out on the other end. The reason transformers only take AC is that you need a a changing current to create a changing magnetic field to induce a current in the secondary winding. No change no induction.

Q: I am a transformer factory salesman, the company let go to the field to run business, if you go to a strange city, where the main starting from where the few places, and which units to contact? If the local sales in the transformer factory, then work well to carry out? What are the sales channels?: 1. Power supply company tender 2. Cabinet manufacturers 3, the installation company 4, direct customers, to the planning bureau to find, in advance to know which new project 5, design institute, know some late 6. Power supply company front desk, people come to install more late

Q: Do you really think Transformer 2 is any better than Paul Zart Mall Cop? Not that Mall Cop was a good movie. Transformer 2 just went on and on, boring, boring.: Transformers 2 plot, action, comedy Mall Cop comedy What do I like better: Transformers You just like pure comedy, that's all. Don't compare it to Transformers.

Q: The total power of 590kw, this transformer can bear it? It is best to give a formula, do not copy the.: 630KVA transformer generally according to the efficiency of 0.8, about 504KW load, the capacitance compensation will increase the power factor to 0.95, the load power also increased with about 590KW near the existing total power 590kw should be installed capacity, the actual load should Less than 90% can load. 630KVA Transformer rated current: I = P / 1.732 / U = 630 / 1.732 / 0.38 ≈ 957 (A) The total installed power of 590kw, load rate or full load rate of about 0.9, the capacitance compensation to the power factor increased to 0.95 when the average power factor of about 0.9, the load current: I = P × 0.9 / 1.732 / U / COSφ = 590 × 0.9 / 1.732 / 0.38 / 0.9 ≈ 896 (A) 300kw load current (when COSφ is 0.8): I = P / 1.732 / U / COSφ = 300 / 1.732 / 0.38 / 0.8 ≈ 570 (A) Large cross-section copper wire per square safe current carrying about 2.5 ~ 3A, need to wire cross-section: S = 570/3 = 190 (square)

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: 1. No Jetfire isn't that old. although his age might be a little higher than others. 2. Omega Prime is a fusion of Optimus Prime and Ultra Magnus. So technically the answer is yes and no because it's actually Optimus Prime fused with another transformer. 6. Not really. It was just extremely stereotypical and a little annoying. But if you think that all stereotypical representations in movies are racist, then you'll have a problem watching any movie. Take asian stereotypes for example. 8. Pretenders (what the human changing robot is called) were first conceived in 1988, I think by Marvel Comics not sure about that. And yes it was in the Marvel Comics production of Transformers cartoons. 9. Yes, in the cartoon series they were able to merge into a larger Transformer called Devastator. 10. No, Starscream always tried to take control of the Decepticons behind Megatron's back or when Megatron is injured (eventually he is killed by Megatron-turned Galvatron). Jetfire is the Transformer that switched sides from the Decepticons to the Autobots. 11. The Decepticon's name is Soundwave.

Q: i have an epcos 565-2 transformer and i want to know how much it will raise the electrical output of a standard 1.5 volt battery. i really do not know much about transformers, but i bought a motor, assuming that i would be able to do fun things with it, and i hooked it up to all the power i could(solar batteries, and numerous amounts of AA batteries) but it wouldn't spin anything that i attached to it more than probably 60 rpm. i bought a transformer to boost the power, and spin the motor much faster. the motor is graded for 3000 rpm maximum, but i just want it to be above 250. any help would be appreciated.: Transformers will only work with AC, not the DC from a battery. You will have to buy/build an inverter circuit to convert the 1.5 V to anything higher with a transformer (the transformer may become part of the inverter if it is the right kind). The other thing to think about is the power level. A 1.5 v AA battery is good for this much power: 1.5 volts * 1 Amp 1.5 Watts You might get 2 Watts out of it for a few minutes, but it can only sustain 1.5 to 2 Watts for about an hour. How much power is the motor rated for? If the motor is rated for 10 Watts, then 1, 2, 3, or even 4 AA batteries will not be enough to power the motor much above 250 RPM. There is still alot you need to know. Just for fun try a bunch of D cells in series (about 10 of them) The extra current provided by the D cells may spin the motor faster. .

Q: I am very dissapointed because i lovvvve transformers but how can the movie go on without her? I know i know. the show must go on. but cmon. i hope they pull it off., does anybody know why megan fox isn't going to be in it.: Cus she said in interviews how much she hates the director and the transformer movies.
