Description

The application of 400MVA/220kVmain 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 400MVA/220kV main 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 400MVA/220kV main 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:1000KVA transformer power loss is how much: It depends on its kind of transformer oil-immersed transformer or dry, 1000KVA dry-type transformer no-load loss of about 1.5% to fill the load loss of 3%, oil-immersed transformer no-load loss of about 3% to fill the load loss of 5% The above is just for reference, because each manufacturer has a difference.

Q:how could I describe the physics of transformer?: A device by which you can increase or decrease the available AC mains voltage.

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:how transformer came to know that it has to draw lagging current during summers: it does not have a clue about seasons. transformers are inherently inductive devices and thisn means current lags any day of the year

Q:I want to get the asus transformer, and on the web, there is stuff like asus transformer prime, and i want to know the differences between both and the negatives and positives of each. Asus transformer prime is $100 more than the asus transformer, so I want to know if it's worth it or not. Thanks!: Yes the transformer is different and older than the transformer prime. It has NVIDIA Tegra 2 processor vs the tegra 3 in the prime. Tegra 3 is a quad core 1.3 ghz processor and the tegra 2 is a 1ghz dual core. You should definitely get the prime but dont buy it yet. ASUS sold out the first batch which had a few issues, and they are releasing the bugs fixed second batch soon with Android 4.0 Ice Cream Sandwich pre installed (I could be wrong here), so wait till then and buy it with the keyboard dock which doubles the battery! I'm waiting for the prime to come out soon too! It is very thin and thinner than the galaxy if not the same. Hope this helped.

Q:100kVA transformer can withstand much of the current? What is its formula?: For safety insurance, the current density is about 3.0, S = 144.34 / 3 = 50 (about) So take the 50 square cable can be.

Q:I'm 13 and I love the Transformers movie, TF Animated and TF Armadaactually, those are the only ones I HAVE seen so farI'm just wondering where to start with attempting to watch them all? And in what order? Or, doesn't it matter? I suppose it does with G1 and 2Where on the internet can I watch them? Any recommendations?Please answer! I really want to have seen every one!: not okorder

Q:I really want the transformer but if i buy it i have to wait for shipping. But on the other hand if i buy either one i have to wait 2 weeks for the other.: Killzone 2, hands down!

Q:I'd recommend a big Transformers fan for this please. So I have a Transformers series that I'm working on for fun, and I want an awesome name for it. It has Unicron in it and the Autobots and Decepticons team up to take him down. A name for that part is Cybertron Alliance. But I also need a name for story with events that take place before that, when the Bots and Cons were at war. Please help!: Huge transformers fan? you got me ;D Sounds pretty cool. can I read it when youre done? The Ultimate Alliance Rise of Unicron it would be great if you could add more details so I could think of more names : just give a rough outline perhaps?

Q:I have two questions about electrical transformers1.Do all transformers come with wires so I can hook it up and plug it into a wall? If not, where can I get those?2.If I don't have anything to sauter wires, could I use eletrical tape instead? Which sounds sloppy.: 1) okorder
