Description

The application of the 40MVA/20kV split auxiliary transformer, and matches well with the transmission capacity of UHV 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/20kV split auxiliary transformer. In order to make the products applicable to any UHV substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity UHV 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 UHV 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 UHV 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 UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of the 40MVA/20kV split auxiliary 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 UHV Transformer products.

Q:I have a few power tools, none of which are natively wired for 110-240v. In particular, a portable table saw, a router, and a mitre saw, all at 220v. Since the resale value of them are so low on auction sites, I was thinking of taking them with me when I shift home to the states. Would it be safe using those tools, for extended periods, whilst running them on a transformer?: You can do that. Just make sure the transformer is rated for the power they will draw. Keep this in mind: American homes are wired with 220 volts. Only, they split the voltage into two 110 volt legs. Each leg to ground (or neutral) is 110 volts (also commonly referred to as 120 volts). But from one leg to the other is where you get the 220 (or 240) volts. My garage is wired with two legs of 110, which means I have 220 out there. I also have an outlet for 220 volts. Because some of the power tools I run demand more current, and run them simultaneously, the standard 110 outlets struggle to meet the demand. So what I did was to take a dryer cord and wire it into a pony panel where I can draw 110 volts from one leg to ground to power a table saw while the other leg powers the dust collection system. To try and run both those pieces of equipment on a single 110 line means a trip to the breaker to reset it because each draws enough power that when used together they draw more current than the circuit is safely rated for. YOU can do something similar. Just make sure you use a 20 amp outlet meant for use with 220 volts and wire into the panel (if not already wired) and set up a 220 volt plug where you will be using these power tools. Using a transformer will work, but the more you couple the power magnetically the more inefficient your system becomes, and you waste power. Also consider just buying tools rated at 110 volts. They're plentiful and cheap enough that the cost may offset the cost of shipping these 220 v tools. Throw in the cost of a transformer and you're probably spending more money in the long run. Hope this helps. '')

Q:i took it out. on one side of the transformer i have a black and a red im hooking those up to a battery on the other side i have five wires 2 red, 2 white, and 1 blue i dont know what these do or how to get current to them. does anyone know how to complete the circuit???: A battery puts out only DC, and a transformer needs AC, so this will not work. Do NOT try to build a shocking device, you are too young to spend years in jail. It's impossible to pick a voltage that is felt as a shock by some people without killing someone else. .

Q:800kw motor how much transformer: 800kw motor can generally choose 0.8 motor power in about 800KW with 1000KVA. Motor power in 1400KW or so with 1750KVA. If you are equipped with reactive power compensation (in general, the power company also requires you to match, if the power factor is less than 0.9 Is to be fine) Transformer can also choose a little smaller, like 1000KVA transformer power factor of 0.9 when you can take 900KW load. Can also be based on

Q:What is the primary side of the transformer: Introduction: Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.).

Q:Is the transformer a power adapter?: No, the transformer should be a device that performs impedance matching in order to achieve maximum power transmission. In turn, "power adapter is a transformer" is also unsatisfactory, at least the general power adapter contains a transformer. As a power adapter requires a common power supply into a device required power, voltage, current, impedance and other aspects of the match, of course, it needs a transformer. Since it has the function of changing the voltage, call it "transformer" is no harm. I would like to say that the power adapter is not only transformer, it needs to achieve in addition to the voltage other than the parameters of the match, for example, the most simple general-purpose DC adapter in addition to transformer that there is a "rectification" process. The transformer, narrow sense that it is just a component only, like resistors, capacitors, transistors and so on.

Q:I broke a small transformer that I found inside of my DVD player, and I would like to have one (not for the DVD player, just separately) I would like the transformer to take in low voltage, such as a few AA or AAA batteries, and I want it to scale that up. Does anyone know where I can get one? If not are there any instructions on how to make an effective yet inexpensive one?Thanks in advance!: A transformer cannot step up or step down DC power. (All batteries are DC). That is part of their nature. A basic transformer is nothing more than two (or more) inductor coils in close proximity, often with a steel core to help with the magnetic fields. All inductor coils are basically a coil of conducting wire, most often copper.

Q:I am building a simple circuit and was wondering what is the difference between a coil and a transformer? Also, in my circuit I have a generator. My generator is made up of a coil and magnets. I would like to know do the amount of turns my coil is determine the power of the generator? When I select the gage wire I am going to use we that determine the amount of volts and current I can gain from my generator?: A transformer is nothing but a magnetic core on which two isolated coils are wound. Power of generator depends on many factors 1. Size and strength of magnet 2. Size and magnetic properties of iron parts 3. Rotating coils, speed, diameter, length. Gage wire is chosen based on volt / ampere considerations, not the other way.(gage does not decide voltage and ampere of the generator)

Q:I am looking into purchasing a counter top coffee roaster that requires a 30 Amp 120 outlet; manufacturer says it uses about 21A.The only plug/circuit that can handle this load at this time is a 240 V outlet. We have a gas stove and we are not currently using the circuit.Does anyone know of a manufacturer that makes a external/freestanding step down (240 to 120) voltage transformer / regulator that I can plug into a grounded (North American) 220V outlet ? Note: a) I don't need it to be variable, just a fixed 240V to 120V is perfect. b)It would also need some sort of internal voltage regulation/ stabilization as erratic voltages would affect the (coffee) roast.: Install a 125 volt 30 amp receptacle where the oven outlet is and rewire for a neutral in the breaker panel.

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 just heard from a guy who works with either the electric company or construction that the transformer behind sams club(where i work) caught on fire and its going to be a long term job. The power is out for them, walmart, kohls, and like 10 other large businesses nearby. Anyone have any idea what kinda time frame that would be to fix that? I wanna know if I'm going to be out of a job for a few days or not. Its too late to call and ask. So how long does a transformer take to repair/replace?: If the transformer belongs to the utility company, then they usually have it replaced within 24 hours. If it is privately owned then it could take a week or more.
