Description

The application of the 260MVA/800kV single phase water cooling main transformer for the hydro power station.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 260MVA/800kV single phase water cooling main transformer for the hydro power station. 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 260MVA/800kV single phase water cooling main transformer for the hydro power station, 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 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. Transformers don't usually have plugs on them. 2. The word you want is solder. Tape will work, but it is sloppy.

Q: What is the meaning of the transformer capacity unit KVA?: KV.A is the capacity in the transformer KVA for apparent power, its size and power factor! For example: power factor cosΦ = 0.8 active power P = 1Kw Then tgΦ = 0.75, so the square of the apparent power S = the square of P + the square of P * tgΦ When the power factor is 1, 1KVA = 1KW

Q: i bought transformers a few months ago, and i finally watched it last night.my nephew watched it and i guess got something on the dvd.i was at the ending where they rolled bumblee in on the truck and the cube was destroyed and all that and optimus prime was saying they lost a great ----- i can't remember extactly what he said.anyway, right after that, the cd skipped and went do directly to the credits.what did i miss?: Optimus is saying they lost a great warrior (or something like that, refering to Jazz). Bumblebee askes if he can stay with the boy, and he does. The end shoes Shia and the chick laying on Bumblebees hood and the other main Autobots around and Optimus is giving some speech (I can't remember).

Q: What is the SN on the transformer? What is the difference between it and the actual power of the transformer?: Corresponding to the line of fire and the zero line, there is a L is the ground

Q: Transformer 1KVA can load how much security, how to calculate the formula: This is based on the voltage count, such as three-phase 380V. 1KVA current is basically 1.5A

Q: I have an RCA 46 inch projection Tv model p46924 that doesn't turn on. Someone said I probably need a new transformer. What is it? What does it do? Where is it located?: Unless the someone was an experienced TV Tech you can take his ( or her ) diagnosis with a very large pinch of salt ! To answer your basic question though what is a Tv transformer ? I will list a few transformers that can be found in a TV set.! Mains AC transformer already described by TV Guy ! Sound IF transformers ( 2 or 3 ) Vision IF transformers Power supply switching transformer ! Line drive transformer . Flyback Transformer A couple or so in the tuner unit. No doubt I have missed a couple and will be picked up on it by the other TV Techs who may decide to answer this question but you get the idea don`t you !! Cheers Pete To be fair Adrian he did say with other circuitry . Cheers Pete

Q: Transformer secondary side is high pressure or primary side is high pressure: Step-down transformer primary side is high pressure, secondary side is low pressure. The step-up transformer is just the opposite. Step-down transformer reverse use is the step-up transformer.

Q: I know there has been plenty of Transformers anime over the years, but is there any Transformers manga?: Have you tried googling it? Good luck! I remember seeing Transformers in JPN since I was little I think they've been around since the 80s. At least I've seen the toys in JPN since then.

Q: I read something somewhere once about using small mains transformers as substitute speaker transformers in valve circuits.Suppose I have a 6-0-6V transformer with a 240V primary. That gives a 20:1 turns ratio. So if the secondary is putting out Vs volts at Is amps into 8 ohms, then (neglecting losses) the primary will have 20*Vs volts across it and Is/20 amps through it. But we know that Is Vs / 8; so the primary will appear to have an impedance of (20 * Vs) / (Vs / 160) 3200 3.2k ohms.Am I thinking right? Or will the presence of DC in the primary ruin everything?I'm thinking of using an ECL82 (aka 6BM8) for my first project, as that has both a triode and a pentode with separate cathodes and seems to be available still. Is this a good choice?: Mains Transformers

Q: i just got back from seeing transformers and the special effects were awesome but the storyline could have been better. I thought the girl meghan fox was so prettywho thought the same?: Well, you can call me nuts! It was so goood, I watched it FOUR times. So good, I'm thinking of going for a 5th! (4 is bad luck!). To me, Transformers just broke the barrier when it comes to making robots that interact well with humans. The awesomely human-like behaviour of the Autobots, the cool action scenes, fast but cool transformations and the god-like Optimus Prime took my breathe away! Absolutely the best movie this year. No one could ask for a better live adaptation of a cartoon, especially one that we used to love.
