Description

The application of the 370MVA/525kV single phase double winding generator 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 the 370MVA/525kV single phase double winding generator 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 the 370MVA/525kV single phase double winding generator 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: A transformer is a two coil component that uses electromagnetic induction to pass an AC signal from its input to its output.?How and why are transformers used on electric wires? What would be their purpose??Why do we hear that these transformers break at times?: Transformers are mainly used to step up or down of a voltage. For example, generators output are normally in the magnitude of 100 volts per phase or so for a 3 phase system. When the output is to be delivered to the users, sometimes, it could mean 100's of miles away. We all know loss will naturally occurs during the travel of the power. So it would be necessary to jack the voltage up to thousands of volt at the source and then at the substations local to the users return to the normal main voltage, such as 240 volt in UK and 110 voltages in USA. The process is done by transformers and can only be done by AC (not DC) system by making use of the turns ratio of the Input/Output of the transformers. Transformers carry power and sometimes the insulations between wires in the coils breakdown which in turn causes transformers to breakdown.

Q: can someone please give me transformers war for cybertron ps3 controlls: Don't know

Q: I have halogen lights in my basement. When i mean contact i am talking about this little hanging jack where by you plug in the light bulb into. For some reason, one of my lights are not working properly but I have already tested the light bulbs out. I have a feeling that the contact/transformer (hanging jack slot) is ineffective. Does anybody have an idea how to change these things?: You are putting too much energy into the transformer. You need a circuit breaker in your circuit in order to reduce the amount of power that goes through the transformer. Because so much power is going through the transformer, it can only put out so much, so fast, and, therefore, your halogen lights are not turning it on. You can google circuit breakers or resistors, or take the lights in to any hardware store to see if they can fix them.

Q: How to tune to 14V? Why I tune the value of the above voltage meter has been always beating.: 2, in the Proteus simulation diagram, double-click the transformer symbol, open the transformer parameter settings dialog box, which ??????????????? Primary Inductance 1H (set: can be fixed) ??????????????? Secondary Inductance 0.00406H (set by press)

Q: I went to go see transformers yesterday and one of the previews shows a bunch of people at a party with someone videotaping the party. Then there are explosions in the distance and at the end the head of the statue of liberty lands in the street. They don't say what the name of the movie is but it has a january of 2008 release date. Does anyone know the name of this movie?: This okorder

Q: I own a 1973 house and want to do a little remodeling. It has a 25foot hallway with 3 (old fashioned) ceiling lights that I want to replace with recessed lights. I went into the attic to look over things - looks like each e-box is made of bakelite which makes sense due to its age, attached to a rafter. However, there appears to be a transformer with what looks like low voltage wires -redwhite- on top of the box.Can a qualified electrician please tell me what this is and do I need to worry about it when I retrofit to recessed cans?: I'm not an electrician, but I have a few ideas. First, Do these lights use standard incandescent bulbs, or something else? If they are plain ole incandescent bulbs, I'm left wondering what is going on. If I understand you correctly, each of the three lights has an old bakelite electrical box with its own transformer, with regular wiring coming into it, and low voltage coming out of it feeding one light fixture below. If thats the case, then you are going to remove the transformers along with the fixture. However, if its one transformer that feeds the three fixtures, then you have a low voltage light system and will want to remove the fixtures and transformer and run new electrical wire (Romex) to each of the three new fixtures. The previous answer was correct in that most houses only have one low voltage transformer that powers the doorbell buttons and chime(s). Some homes back then had intercom systems and/or security systems that would require a transformer. Another point: check the smoke detectors. If they are over ten years old, replace them. They only work for about 10 years (even the new ones).

Q: I am re-winding transformers, and I was wondering if braided copper wire can be used for the secondary winding. I will be using large gauge wire (4-8 ga.) and I just need to know if the performance will be terrible if I do use it.: I assume that you are talking about stranded wire with plastic insulation. The strands are not actually braided, but only twisted together. There is such a thing as braided wire, but it is a special product for high frequency. The plastic insulation, usually polyvinyl chloride (PVC) will likely get too hot in a transformer. The stranded wire with PVC insulation is also much thicker than magnet wire of equal copper size. The number of turns that will fit will be greatly reduced. You can probably not successfully strip of the PVC and put on a varnish type insulation. If you wind the transformer with PVC insulated wire, the number of turns that will fit will limit the available volt-amperes to some extent and you may need to limit the load even more because the safe temperature of the PVC insulated wire is much lower than the safe temperature of magnet wire. Edit 1 Duty cycle is certainly an important factor affecting operating temperature. That could allow PVC wire to work. There still might be a problem with getting enough turns in the space available. You might consider going to a motor rewind shop to see if they will sell a small amount of magnet wire of the proper size. If you have cheap PVC, try that first and estimate how many turns you need if you need more. Magnet wire can safely run hotter, so smaller gage wire can be used. You could also see if recycle places will sell recycled magnet wire. If you can get magnet wire somewhere near large enough, you could use two or three strands in parallel.

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: Since they are both 100 VA units, capacity seems to be OK. The voltage however should be checked further. For example, you say the unit you removed was 230 volts in and 100 volts out. This is a ratio of 230/100 2.3 to 1. Thus if you have 230 volts on the high side of the transformer, you will get 100 volts on the low side of the transformer. If the new unit you purchased is 230 volts in and 110 volts out then the ratio is 230/110 2.09 to one. So if you have 230 volts on the high side you get 110 volts on the low side. However, I suspect the new transformer is rated as 240 volts high side and 110 volts low side for a ratio of 240/110 2.18 to one. So f the input is 230 volts you will get 105.4 volts on the output. Thus the increase of the output may only be 5 volts, not 10 volts. Bottom line is that the new transformer will work just fine either way. Over-voltages due to switching surges may be ignored as most designs have already taken that into account with voltage variations of +/- 10% normally. Hope this helps, Newton1Law

Q: And what are the prospects for Transformers 3? I mean, should i just skip it?I forced myself to watch Transformers Twice. Didnt care for it much, either time. Barely, BARELY passable.: I agree! I loved the first Transformers. But the second oneugh! The only thing I liked in that movie were the amazing special effects on the robots. Anyway, here are the reasons, it sucked: 1) Michael Bay did not follow the original script/story that screenwriters Orci and Kurtzman laid out. Here's what they said in an interview: We were very surprised when we saw it, too, and it’s a choice that was made. If anything, it just shows you that we don’t control every aspect of the movie. 2) Production was rushed to meet the premiere deadline. 3) Autobots got shoved to the side for more extended human drama military action. 4) Too much attention spent on CGI at the cost of crafting a good story or character development. 5) I really think Steven Spielberg (exec producer) had a hand creatively in Transformers 1. I guess he was really distracted by other things during the making of the sequel. Shia Labeouf sums it up perfect: We got lost. We tried to get bigger. It's what happens to sequels. It's like, how do you top the first one? You've got to go bigger. Michael Bay went so big that it became too big, and I think you lost the anchor of the movie. I suggest viewing Transformers 3 with very low expectations.

Q: HI I recently heard a linkin park song and I forgot the title of it. My friend said this song is a theme song or something that's in the transformer movie I want to know the title of the song please help: It's called New Divide, and yes it was the theme song for the newest Transformers movie.
