Description

The application of the 360MVA/63kV main transformer for 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 360MVA/63kV main transformer for 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 360MVA/63kV main transformer for 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:Which transformers belong to special transformers: Transformers are generally used for AC voltage conversion if used for other purposes such as changing the frequency of the power supply, rectifying the power supply of the equipment, the power supply of the welding equipment, the electric power of the furnace or the voltage transformer, the current transformer. These special-purpose transformers are known as special transformers. Because of the working conditions and load conditions of these transformers, they can not be calculated by the general transformer calculation method.

Q:Transformer rated capacity 500 / 750KVA (AN / AF) What does it mean?: Transformer under natural cooling conditions, the maximum capacity of 500kVA, air-cooled conditions, the maximum 750kVA A refers to air, N refers to the natural cycle, F refers to forced circulation

Q:i have plenty of 3 phase 220 in my shop, but one of my machines requires 440 3 phase. i was going to use a 75 kva transformer with 440 primary 220 secondary in reverse to supply the machine. it is a 15 hp motor 40 amps. i figured my minimum kva requirment to be 37.5 but more cant hurt for the potential high cutting rates i may need to achieve. i simply wanted to buy the transformer, hook the 220 3 phase supply to the primary, and the output to my machine. I think this will provide me with 440 output. the motor plate says 7-1/2 hp/15- hp. 40/20 amps. Any help is welcome, i hate to buy the transformer and not have this unit work. i would change the motor wiring, but the diagram is gone, and the wires are not numbered, also i believe id have to change all the heaters, which are hard to come by, as well as various other parts in the panel. just seems the transformer is the easiest way to get this machine up and going in prouction.: Welll yes and no. The voltage ratio reversal is OK but one must remember that when going from 220 to 440 the amperage is cut in half in availability and when going from 440 to 220 the amperage is doubled in availability. Now here comes the NO partyou specified three phase.make sure that's what your input and output are and a 220 is generally wired star with a center tapped ground or delta with a corner ground. Look at the x-former before wiring it up it should have a schematic showing the connection details. Also in transformer reverse hookup with existing equipment make sure the secondary (440 side is large enough to do the work) . Like i said before you will get a loss in ampacity from 220 to 440 .here's is how to calculate it.P(watts) I(amps) x E(volts) x 1.732(sq rt of 3) just substitute in 220 and 440 in for the same wattage you stated (75,000) and solve for Ior you can look it up there are lots of transformer handbooks which explain ratios and transformer wiring out there.One of my favorites which you must purchase is called the Ugly's book of electrical facts. Sounds odd , has lots of good stuff in it for electriciansFrom the E.

Q:I use transformers in my circuitry all the time but when a transformer is say a secondary 12v 1a transformer than what does it mean by 1 ampis it that the secondary winding wire will pop after 1 amp doo to the simple thinness of the wire? or that the ohms of the secondary coil, when using iv/r, 112/12so does this tell you that the coil is 12 ohms?please don't give me other information about the transformer just answer the question please.: It simply means that the maximum safe operating load on the transformer's secondary is 12VA. The maximum safe operating power this transformer can furnish (12 V)*(1A)*(power factor of load's impedance). Power factor is always equal to or less than 1. Power factor cos [arc tan (XL - XC)/(R)]

Q:A step up transformer increases 17.7v to 120v. what is the ratio of the current in the secondary compared to primary? Assume 92% efficiency.HELP PLEASE: Sec Curren Ratiot 17.7/(120*0.92) 0.136

Q:If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts? Please help, thanks so much!lt;3: If you connect them in series, you will get 24 volts. It's not a real good idea to connect them in parallel.

Q:I have a bulb that currently uses a 120V primary to 6V secondary transformer. The load is a 30Watts. I would like to know what transformer I could use to power 8 bulbs (6v 30W each) ? Thanks. How can I calculate that?: Assuming you wire the bulbs in parallel. You need a similar transformer (6v secondary) but one that is rated at 240 watts (or a bit more), 40 amps. Note that the current will be 40 amps and will need quite a heavy wire, #4 or 5. You could also put the bulbs in series, and would need a 48 volt secondary, still at 240 watts. You would have problems of any series string, if one bulb goes out, they all go out. You can also use parallel series combos, 3 pairs, or 2 strings of 3 each as a compromise. edit. Later thought of another alternative that may help. Get a transformer with a 12vCT 240W secondary. Wire like you would 2 phase house wiring, 3 bulbs to each outside terminal, and all 6 to the CT. This means the wire only has to handle 20 amps and can be smaller, and you will not have the series string problem. 12VCT transformers are fairly common. Or if you can find it, and the wiring is still a problem, get a transformer with 2 secondaries each of 12VCT at 10 amps.

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: Hey, well if it's light M or teen or lower, Bully is not for you. THis is way too. influential especially for minors. Transformers on the other hand is a kid's game, and way too easy but way fun especially when you're controlling the Decepticons! It's surprisingly short though. In summary, if bad words, beating up kids. doesn't bother you, puzzle solving, and if you're patient in looking for those collectible like any GTA type of game, I'd go for Bully! If you're up to a fast-pace gaming, transforming mid air or while driving, jumping over buildings and wrecking half the city is your thing, go for Transformers! I finished both games and I give both two thumbs up. Buy both if you could. :) Enjoy!!

Q:can the amps rate be increased by using transformer from 10amps to 120amps.: Transformers can increase or decrease the current, they can also do the same to the voltage. So yes transformers can increase the current but it will decrease the voltage at the same time. Hope this helps!

Q:I need a specific transformer to make 5V go up to 170V. It can be a little high and I can just use a potentiometer to lower it if needed. Where can I find such a specific transformer?: Since okorder
