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 been telling everyone that I would never get the IPad because it doesn't do anything. A tablet is a great idea, but the IPad has way better potential. The IPad is currently useless. You could have music, movies, web on the go, books and games with an ITunes App store. Those are pretty much the highlights.The Asus Eee Pad Transformer on the other hand is a tablet that has music, movies, web only with wi-fi, books games, Android App market, and what i'm really looking for in a tablet, the ability to view and modify microsoft office documents (word, excell, power point). The advantage that the Transformer has is a detatchable keyboard, so it can be used as a type of netbook or tablet. The plus about the keyboard dock is that when your tablet needs charging and you connect it to the dock, it will recharge your tablet. Total battery life of the tablet plus dock is 16 hours(8 hrs/e).So now, is ther anything out there similar to this Eee Pad Transformer worth considering? Should I get it or not?: asus transformer is definately better than the ipad2. so far ipad 2 is nothing more than a fancy toy to glare at other than design cant give it any props. it makes even less sense to buy if you already have an iphone cause the only difference between the two is the size of the screen.

Q:The specific steps and procedures for installing the transformer: Hello, you said it should be the frequency transformer installation steps it. Steps are as follows: first equipped with skeleton Oh, and then use the winding machine around the enameled wire, and then add the fuse (if the customer specified to), then dip tin, dip tin is the dressing, the package is finished shake the film, shake the film is Plus shell, such a transformer to do a good job. I hope I can help you.

Q:How does the core material affect a transformer? Such as if you use steel vs. air. Or wood vs. magnet.: A transformer is a gadget that converts an alternating (A/C) modern of a definite voltage to an alternating modern of diverse voltage, without substitute of frequency, via electromagnetic induction. A 'step up' transformer gets a low voltage and converts right into a miles better voltage, and a 'step down' transformer does in basic terms the opposite.

Q:How to distinguish between large, medium and small transformers: 3, according to the use of points: 1) power transformers: for power transmission and distribution system of the rise and fall voltage. 2) instrument with transformers: such as voltage transformers, current transformers, for measuring instruments and relay protection devices. 3) test transformer: to produce high pressure, the electrical equipment for high pressure test. 4) special transformers: such as electric furnace transformers, rectifier transformers, adjust the transformer, capacitive transformers, phase-shifting transformers. 4, according to the winding form points: 1) Double winding transformer: Used to connect two voltage levels in the power system. 2) Three-winding transformer: generally used in power system area substation, connect three voltage levels. 3) Autotransformer: Power system for connecting different voltages. Can also be used as a normal step-up or down transformer. 5, according to the core form points: 1) core transformer: for high voltage power transformers. 2) Amorphous alloy transformer: Amorphous alloy core transformer is a new type of magnetic materials, no-load current drop of about 80%, is the energy-saving effect of the ideal distribution transformer, especially for rural power grids and developing regions such as load rate Lower place. 3) shell transformers: special transformers for high current, such as electric furnace transformers, welding transformers; or for electronic equipment and television, radio and other power transformers.

Q:What is the SN on the transformer? What is the difference between it and the actual power of the transformer?: What you say SN is the rated capacity of the transformer, the capacity is also called the apparent power. It represents the maximum power that the transformer can transmit in the rated state, that is, the maximum power that the transformer can transmit when the power factor is 1 is SN kW. Transformers are only used to transmit power, in addition to their own no-load loss and load loss, the power does not consume. The actual power it delivers depends on the load.

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:I have a power transformer and i forget where it came from. It has two leads from a wall outlet plug and then goes to the main (square) casing. there are three wires that come out the other side. They are from left to right, red,white and red. I assume its a 9v ac to dc transformer but am not positive. Can someone help me? I suspect that the white wire is ground. Any help would be great.: There's no reason to assume anything, except that the primary side (with the line cord and plug) is probably intended for 115 Volts, AC. If it's a transformer (rather than a power supply) it's not AC to DC at any voltage. Transformers convert AC to AC. With those colors on the secondary, there's a pretty good chance it's center-tapped. Red-to-red will be twice the voltage of either red-to-white. Nothing should be grounded to the transformer case.

Q:I was wondering what year is transformer 2 cuz the first 1 was freakin awesome!!!!!!!!! and i wanted to see a second 1 but dont know which year and i heard there was going to be another one transformers 2.: Their okorder

Q:Hello everyoneA 240-110 stepdown transformer is used with quite a lot of equipement in my home and I have recently become a bit concerned about the effects that they have on the equipement.Thanks to some web page I stumbled across saying that transformers can 'overheat' your equipement etc.And since most transformers aren't made by any big name brands, there really isn't a way to tell if the one in posession is a 'high quality' one or not.So my question is, do transformers actually damage your equipement?Anyone have expertise in this area?Thank you very much.: The only problem I have seen or heard of with transformers is. A Delta transformer has a wild leg, meaning one leg has more or less current that the other legs. Were as with a ( Y) transformer all legs are equal. The only time you will have trouble with a transformer is when it does not supply enough power for the equipment it is supplying. This causes low voltage and high ampage which burns out equipment. Most all power company's are now using (Y) transformers. If you have any question, call your power company, or have an Electrician check your power.

Q:i need a little help with my homework. if you bank three single phase dual voltage transformers in a delta connection for the primary and do the same for the secondary, do the kva of primary add together or do the kva stay the same because it is connected in delta.it's a 2:1 480v - 240v each transformer is 5 kvais the total kva when connected in delta 15 kva or 5 kva and do you use the formula Pa line current times line voltage times 1.73 to find the rated load current.thanks in advance: Delta connection it's mean you give 480 V 3 phase, and output 240 V 3 phase. So the total KVA in delta is 5 KVA and the formula like you said. Pa I (current) x Volt x 1.73 (three phase) x cos Q (Cos Phi).
