Description

The application of the 40MVA/220KV startup/standby OLTC transformer, 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 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 40MVA/220KV startup/standby OLTC 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 OLTC transformer 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 OLTCTransformer’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 40MVA/220KV startup/standby OLTC 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 UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q: I have a packaged heat pump w/ Emergency Heat that is not working and does not come on at all. No lights or anything even when I switch it to emergency heat. Someone said that it could be my low voltage transformer. What is that and how do I check it?: You need to check the breaker fist and the disconnect on the unit. Then after verifying with a Volt meter that you have power. Your going to need to remove the panel on the unit. There should be a circuit board with a LED light blinking (this is assuming you have power), Count the number of flashes the look on the back of the panel or the installer manual. This will give you the fault code of what has failed. To test the low voltage transformer, again you need to verify that the unit has power. You will need to use a volt meter. The other possibility is you have a failed contactor or failed capacitor. To veriy your thermostat is working try turning on the blower (fan) to ON. If the fan comes on then you have power to the unit, and your low voltage transformer is working. Also, if your thermostat has batteries in it and if they are dead this will cause a no heat issue. Heat pumps are not easy to trouble shoot via the internet. I highly recommend you call a professional out to properly fix the unit. Remember IF you decided to go fishing and try and fix it, your dealing with HIGH voltage and sensitive electronics. So, poking around really is not a good idea.

Q: hey Guys. I'm a big fan of Transformer movies. can't wait to see the Transformers-2. Not a real trailer has been released? :( . I would like to know which robots r going to b in the next epic battle?? :): Soundwave. Optimus Prime 3

Q: 2500KVA transformer bearing current how much calculation: Did not give the voltage data to transformer primary and secondary side rated voltage 10KV / 0.4KV as an example: Primary side rated current: I = P / 1.732 / U = 2500 / 1.732 / 10 ≈ 144 (A) Secondary side rated current: I = P / 1.732 / U = 2500 / 1.732 / 0.4 ≈ 3609 (A)

Q: I can get 1 game and i think ive narrowed it down to bully and transformers. I need you to tell me which one i should get and why. Also you could suggest another game that is light m or teen and lower. thanks: transformer!!!

Q: i am recently watching transformers prime and i am a big fan of all transformers but now i am confused.i generation 1 and 2 was good then they ended.does transformers cybortron trilogy a sequel to g2 or new start and then is tranformers prime a sequel to transformers fall of cybortrons?: 1) In the G1 timeline we have a sequel series made exclusively for Japanese audiences. They completely ignore the events in the American ending and go in a completely different direction. 1) Transformers: Headmasters 2) Transformers: Super-God Masterforce 3) Transformers: Victory 4) Transformers: Zone Then there's Beast Wars and Beast Machines is a sequel/prequel to the G1 series. ___________________________ 2) Transformers: Robots in Disguise (RiD) aka Transfomers: Car Robots in Japan is a complete standalone series, no relation to any other existing TF series ____________________________ 3) The Unicron Trilogy is it's own timeline that has 3 series. US - JP Armada - Micron Legend Energon - Superlink Cybertron - Galaxy Force but the 3rd series, Cybertron, was originally a self-contained series, the American version edits the dialogue to make it appear as a sequel to Armada and Energon. Also, the character Override, who is female in the US version, is male in the Japanese. In other words in Japan the first 2 are in the same continuity and the 3rd is a another reboot.

Q: design a quarter wave transformer to match a 73 ohms antenna to 300 ohms transmission line fed by a 100MHz FM radio station: Transformer impedance required: sqrt (73 x 300) 147.986 (say 148) ohms. The 1/4 wavelength in air is (75/100) 0.75 metres. You have not stated what you are using for the transformer, so you will need to allow for its velocity factor. But the transformer could be 0.75 metres of parallel rod spaced as required for the impedance. I am also assuming the antenna is balanced (sounds like a folded dipole).

Q: I got an Alien bees unit and in order to convert the power from 120v to 220v I have to get a true magnetic transformers according to their website, what does that mean?: All transformers are magnetic. Perhaps if you would provide a link to the product in question, maybe even to its user's manual, some more information could be gleaned that would allow a more helpful answer. I have no idea what an alien bees unit is. -------- Ok with that I was able to google some more info. So you have a unit that came with a 120V power cord, intended to be plugged into a north american AC power outlet (120V, 60 Hz), and you need it to run on your local current, which is 220. You don't have a power brick or wall wart, the AC goes right to the flash unit. Yes? And the specs say it draws up to 6 amps at 120 volts, 60 Hz. What they're talking about is that you need a true voltage conversion transformer (usually this is actually an autotransformer), NOT any other sort of voltage converter. Travel stores in this country (US) sell these small and cheap voltage converters, made to allow use of certain high wattage devices (up to 1500 watts) on 240 even though they're made to run on 120. But they don't use a transformer, they use a capacitor and a diode. They're ok for things like curling irons and space heaters. They're completely unsuitable for anything electronic. You can usually tell the difference between a true transformer voltage converter and the voltage converter by weight. The latter weigh just about nothing. Whereas even a 50 watt transformer will sit fairly heavily in your hand. For a device that pulls 6 amps at 120 volts, you need a transformer of at least 1000 watts capacity. I've linked one below. Of course that is a US seller, but this will give you an idea of what to look for. Note that it weighs 17 pounds (about 8 kg) and is about 5 x 7 x 8 inches (13 x 18 x 20 cm). There just isn't any way these get much smaller or lighter. .

Q: I fried a transformer in my lathe. I went to the electrical supply near my house and the got me a new transformer and said it will work. The old transformer is 3 times bigger. they are both 100VA. the voltage on the original is 230v in and 100v out. It powers the on/off switches for the forward/ reverse micro switches. from the micro switch it powers the magnetic puill in for the contactors. The contactor say 100V.will using a 110v transformer cause and problems or issues?Should I return the one I purchased and order a 100V ?I have work piled up and waiting and really need this lathe operational ASAP.Thank You in advance for any information.Earle: I assume the new transformer is 230/110v? If the contactor coil is rated 110v, it should be fine. Most contactor coils, as with most electrical equipment these days have a large voltage tolerance. However, you need to check that the contactor coil is rated for 110v. You may find it's rated for 100v to 120v.

Q: I just saw the mythbusters use a neon transformer to spark a methane explosion and the arch looked like a continuous irredecent light. So are neon transformers a part of neon lights? That and if you know, what is the inert gass inside the lights?: Neon transformers are used to step up ordinary low voltages (440V) to a very high value. Obviously the secondary currents are very low of order of a few mA. They have nothing to do with neon lights/signs. Neon lights are the lamps filled with neon gas.

Q: 1- the properties of electrical transformers . #92;2-their uses . #92;3-their applications.: 1 - Transformers step-up or step-down voltage in a closed electrical circuit. 2 - Power companies send electricity at over 500,000 volts through power lines. They use transformers to convert their power to this level and a second set which lower the voltage for home/office use. 3 - Allowing you to use electricity at different voltage levels for different applications.
