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:10 (6) What is the meaning of 10 and 6 in the KV transformer?: These numbers refer to the voltage, 10 (6) KV transformer 10 and 6 refers to the primary side of the transformer voltage level is 10kV or 6kV. 10 / 0.4 (0.22) KV substation in the number of "/" refers to the transformer primary side of the voltage level 10kV, followed by the transformer secondary side of the voltage level is 0.4kV and 0.22kV, that is, 400V And 220V The primary voltage is the voltage of the transformer line, the secondary voltage is the voltage after the transformer transformer.

Q:I need to find out.I am a huge Transformers fan.: I have seen both Transformers movies as they are both real good movies you should see both of them

Q:Branch circuit cables are rated for 75?C and feeder cables are rated for90°C. This will be a 3-phase, 575-volt system with four induction motors, specified asfollows:Motor 1: 60 hp 0.90 p.f. squirrel cage motorMotor 2: 60 hp 0.90 p.f. squirrel cage motorMotor 3: 40 hp 0.85 p.f. wound rotor motorMotor 4: 7-1/2 hp 0.80 p.f. wound rotor motorA) Assuming no line losses, find the capacity of the transformer required to supplypower to this system.B) Assume that it is desired to improve the overall power factor for this system to 0.95lagging. Determine, in kVAR, the required capacitance for this power factorcorrection.C) Assume these motors have their windings connected in a delta configuration. Whatwould be the line voltage if they were connected in wye?: I would look in the NEC for the full load amperes of these motor sizes. These are: 7.5 HP9 amps 40 HP.41 amps 60 HP.62 amps The 7.5 HP motor KVA will be KVA 575 * 9 * 1.732 8.9631 The 7.5 HP motor KW will be KW 575 * 9 * 1.732 * 0.8 7.17048 The KVAR of this motor is Sqrt(8.9631^2 - 7.1705^2) 5.3778 The 40 HP motor KVA will be KVA 575 * 41 * 1.732 40.8319 The 40 HP motor KW will be KW 575 *41 * 1.732 * 0.8 5 34.707115 The KVAR for this motor is Sqrt(40.8319^2 - 34.7071^2) 21.5095 The 60 HP motor KVA will be KVA 575 * 62 * 1.732 61.7458 The 60 HP motor KW will be KW 575 *62 * 1.732 * 0.8 5 55.5712 The KVAR for this motor is Sqrt(61.7458^2 - 55.5712^2) 26.9141 The total KVA requirement for all motors running at once is 8.9631 + 40.8319 + 61.7458 + 61.7458, which is 173.2866 KVA (note this is the requirement from a transformer, not the size of the transformer The total KW of all the motors is 7.1701 + 34.7071 + 55.5712 + 55.5712 153.0196 KW The total KVAR of all the motors is 5.3778 + 21,5095 + 26,9141 + 26.9141 80.7145 KVAR The power factor for all the motor is KW / KVA 153.0196 / 173.2866 0.883 I took a short cut at this point and used an application i wrote to calculate the required capacitor KVAR. The results follows: At 0.95 power factor, the motors' KVA will be 161.065 The motors' KW will be the same. The motors' KVAR will be 50.2926 The required capacitor's KVAR will be 53.988 The reactance of the capacitor will be 10.65 ohms The capacitance will be 3.49059248 E -4 Farads You can calculate these values as I did above, if you want to. EDIT Forgot the last answer. The line voltage is the same for both delta and wye. The leg voltage for the wye motor will be 575 / 1.732 331.98 volts TexMav

Q:I am in 10th grade now, taking the IB next year, and I would like to know if a Transformer is good for things like taking notes in class, and working on projects that we might be allowed to work on in class. I would still have a full computer at home for more serious editing, but I would just like to know if the Transformer TF300 will be good enough for school. Also, I am not only talking about this year, but also the IB, which - if you know it, and I hope you do - will be more work and I would like to know, again, if the Transformer is up to that task.: (warning : poor English) Yes, Transformer Pad TF300 good for school. 1. It have a keyboard (optional), you can take notes faster. 2. Likes all others (pads), there have camera, you can take a photo of the board (if teacher allowed). 3. TF300 battery life quit good, with the keyboard even better. 4. We will work in cloud computing in the near future (or now) mostly. Google drive meet your needs for word processing, drawing, creating simple spreadsheet. you can share your works, or finish your project collaboratively with your group members via internet. 5. the chips: Tegra 3 is responsive, the screen: 10 (1280x800) is comfortable, the OS: Android 4.0 is more suited for tablets and it's a better os overall, the brand: ASUS, manufacture the best Android tablet (imo).

Q:I feel that Transformers was because that sh*t was hot! And Shia LaBeouf was pretty HOTT too!: Out of the two, I preferred Transformers as it wasn't quite so silly; the dance club scene in Fantastic 4 - where rubber guy shows off - was pretty stupid.

Q:How much W?: 1. And your material related. If the good material, high frequency loss is relatively small. You can do 15W. For example, 200KHZ switching frequency. 2. If you are on the general market, the maximum control in the following 10W. Switching frequency 50KHZ.

Q:Single-phase and three-phase transformer is what it means: Input and output are single-phase AC is the single-phase transformer. Input and output are three-phase symmetrical AC is the three-phase transformer.

Q:i went to see transformers on july 3rd. they had about 5 or 6 previews before the actual movie started. the very last preview showed and party to someone called bob. he was leaving, going to japan. then the lights went out and a big groan was let out and a earthquake happened. they all went out to the roof, and in the distance, a big orange ball was exploding, shooting out fireballs and lava. they only said it was coming out on january 18 2008, and they didn't give the name.please help, i need the name of this movie: Yeah I have the same question. I went to see Transformers and I was like what the hell? That is a movie made by the no-name brand. I do not think it is I Am Legend, thought that looks like a good movie. That name of the movie was sort of obvious. ^^

Q:I wanted to watch the transformers cartoons but because there is so many I don't know which to watch first, seconds etc.Can you please tell me in order which to watch?I'm watching Transformers Season 1 episode 1 atm.THANKS: Transformers G1 Episode 1

Q:I just heard from a guy who works with either the electric company or construction that the transformer behind sams club(where i work) caught on fire and its going to be a long term job. The power is out for them, walmart, kohls, and like 10 other large businesses nearby. Anyone have any idea what kinda time frame that would be to fix that? I wanna know if I'm going to be out of a job for a few days or not. Its too late to call and ask. So how long does a transformer take to repair/replace?: As long as the power company has transformers and all other damaged equipment in stock, they should be able to have everything repaired soon. It is hard for me to predict how long because there may be other things involved, not just the transformer. Is this transformer on a platform, or pad-mount? Could it actually be the feeder wires that caught fire in addition to or instead of the transformer? Is it possible that the fire damaged feeder wires from the transformer to the stores? If so, the store owner(s) may be responsible for making those repairs. The best way to get an answer as to how long this repair will take is to ask your store manager or owner, for the power company should be willing to give time estimates to them.
