Description

The application of 370MVA/236kV main 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 370MVA/236kV 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 370MVA/236kV 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: 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: Transformers have any way of cooling: Selection of strong air-cooled cooling mode, when the pump and fan lose power supply, the transformer can not run for a long time. Even if no load can not run for a long time. Therefore, two separate power supplies should be selected for use by the cooler. ????When the oil-water cooling method is selected, it can not be operated when the pump cooling water loses power. The power supply should select two independent power supplies.

Q: I am looking for a transformer with an output of 6 volts, and 1.8 amps, or any transformer that can run that cycle. Please, let me know. I've been looking for months now, and cannot find anything. Please help. Where would I buy it? Lowes?: If you don't find it you have got to make it. This is a common transformer. Probably you are finding difficulty with it's current rating.

Q: What is the reactive power compensation of the transformer?: The use of capacitors to compensate for reactive power, improve the transformer's active power output capability.

Q: How to make a current transformer more linear? Except change the core.Thank you!: Ideal linearity is reached when B and H are linear. Use air as medium. It may give less output but linearity will be perfect!

Q: If a transformer is rated for a maximum winding current of 10A, would it be permissible to operate it with 10A of input current when the secondary voltage to the load is 40V? Can you explain to me why?The information on the auto transformer plate wasInput 240V/ 50/60 cy 3HPoutput 0-240/280V 20 ampsThe parallel load resistance is 34.5 ohms: fr76ftfyt

Q: 1. 6volts going in a 12:220v transformeris the output 220v or less, formulas, computations 2. 12v going in 12:220v transformer (1 amp 220VA)core loss, copper loss, eddy current loss etc etc3. 24v going in a 12:220v transformer. is the 220v, lost of power in the input,: #1 - 107.8, assuming 6.0V into a 12.0V:220V transformer, with 98% efficiency. You can find the efficiency of the transformer, by looking at it's specifications. Most range from 98 to 99%. All this depends on the load as well, as a lightly loaded transformer has less loss that a fully loaded one. #2 - 215.6V. In order to get 1A@220V, you will need to supply #3 - 431.2V. 100% over spec, and bound to fail. I do not understand what you mean by is the 220V, lost of power in the inupt,

Q: I just purchased a little halogen spotlight lamp with an Class II transformer that converts 110v-120V to 11.5V. When I put my ears about a 12 inches from the transformer near the wall outlet, I hear a little buzzing or humming noise. Is this normal or is there something wrong?: electric powered Engineers call the vibration of a transformer sixty-cycle hum, and is popular. All electrical energy interior the country is generated at 60 cycles in line with 2d, and because transformers have windings, they'll buzz or hum. different countries generate at 50 cycles in line with 2d. the better the transformer, often the louder they'll hum. i admire music, and the overtones or harmonics of 60-cycle hum will continuously supply a hum it is between a B-flat and B-organic. The B-flat it is two octaves under midsection-C on a piano vibrates at fifty 8.27 cycles in line with 2d. The B-organic 2 octaves under midsection-C on a piano vibrates at sixty one.72 cycles in line with 2d. The hum of the transformer you pay attention maximum in all probability will dominate at a bigger overtone, or harmonic. 60 cycle hum x 2 a hundred and twenty cps B-flat 116.fifty 4 cps (that's the B-flat on the 2d line from the backside of the bass clef). B-organic 123.40 seven cps 60 cycle hum x 4 240 cps B-flat 233.08 cps (that's the B-flat slightly below midsection-C on the piano). B-organic 246.ninety 4 cps I actually have a pal who's has been blind all his existence, and is a lot extra conscious and mushy to sounds. He tells me that he can stay in some shops like Wal-mart for purely see you later using fact the hum from the lights (that have ballasts or transformers) will at last get on his nerves. I even have been conventional to harmonize or sing a song with the transformers in super substations, that are a lot louder.

Q: Do you know what that show is called where there are these dinasaurs, and there are good oens, and bad ones, very similar to transformers.The dinasaurs transform into robots. Whats it called?: I remember a purple dinosaur too. I'm pretty sure it's called Beast Wars, and it is a version of Transformers. If I remember correctly, the Autobots and the Predacons landed on Earth and in order to survive they took form of existing life forms on Earth. The Autobots took the form of mostly animals, but the Predacons landed near some dinosaur fossils so some took the dinosaur shapes. Megatron was a purple-ish T-Rex, and I think there was a pterodactyl one too. Optimus Primal was a gorilla and they had a cheetah and a rat in the Autobots.

Q: I am going to see Transformers 3 today with some friends. Can someone give a detailed summary of what happens in Transformers 1 and 2 because i haven't seen them. Thanks to whoever helps.: here okorder
