Description

The application of 400MVA/220kVmain 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 400MVA/220kV 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 400MVA/220kV 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 know that Cartoon Network showed a couple of commercials for season two of Transformers Animated,but when?To add,the stopped showing those commercials.like,one week after the first time the commercial aired.Did the have second thoughts and decided to cancel it?: Transformers Animated has been cancelled after the end of Season 3. This was announced at BotCon approximately two weeks ago. Currently, there has been no announcement as to what will follow it in the Transformers TV line, other than that there will be something.

Q:Transformer turns around the number and how much V is calculated: 2, seeking coil turns Primary coil n1 = 220 ╳ 9.8 = 2156 turns Secondary coil n2 = 8 ╳9.8 ╳ 1.0 = 82.32 desirable for 82 turns 1.05 in the calculation of the secondary coil turns is the pressure drop when a load is considered

Q:1.) What is the function of a transformer?a.) It is a device that can change the voltage of an AC supply.b.) It can change a low voltage supply into a high voltage supply or vice versa.c.) It is a device used mainly to change AC into DC.d.) A and B are correct.2.) What is the function of a transformer at a power station?a.) To convert DC into ACb.) To produce very high voltagesc.) To produce the currents in the power linesd.) None of the above.: Sorry but I don't know about this

Q:Can someone tell me what happened to the primes in transformers. I know Sentinel,Optimus and the fallen but what happened to the others ?: Depends on the continuity. Traditionally, there were not seven, but thirteen original Primes. Neither Optimus or Sentinel were one of the originals, whether you want to say that there are thirteen or seven. Prime is simply a title given to the leaders of the Autobots, passed down from the original transformers. Since you said seven, I'm assuming you meant movie continuity. In that case, Megatronus Prime, later to be known as The Fallen betrayed the Primes' laws of peace, hence his name. The other six used their physical forms to create a vault in which to hide the Matrix of Leadership from The Fallen. The lore from other continuities is much more interesting however. The fate of those versions of the original Primes range from death, to splitting into smaller transformers and scattering across the galaxy, to living in their own pocket dimension in peace, or to chronicling the history of Cybertron, albeit with their true identity hidden.

Q:Which is good for the transformer?: JMBBZBJZ line lighting transformer, JBK machine control Transformer, SSG Servo Transformer, Low Voltage High Current Heating Transformer, SBW High Power Compensated Power Regulator, SBW-F Splitter Regulator, SVC High Precision Fully Automatic AC Voltage Regulator, Precision Clean Regulator, Microcomputer No Touch Point voltage regulator, UPS, EPS power supply, KSG mine transformers, DN resistance welding water-cooled transformers, reactors, contact-type automatic voltage regulator, column high-power electric voltage regulator,

Q:i heard that there is a new transformers out and i do not know if it is good,so can you help?: Its a hella good movie! I loved it so much! I could watch it again and again. I really don;t get why people thought it was so bad. It was amazing. Seriously you should see it, you would never expect some things that happen and it keeps you interested the whole movie. It is also funny. I loved the first one, but the second blew it away! Go see it! Its worth the money!!

Q:Devices that convert the car battery's 12 V DC into 110 V AC are easily available. The conversion from 12 V DC into 110 V AC is done in 2 steps. One circuit in the device changes DC into AC and transformer changes the voltage. Does it matter which step is done first and why?Any help would be awesome! Thanks!: transformers do not change DC values. Do not hook a transformer to DC. Depending on how the connections are made, it may be a short circuit.

Q:Transformers are hot like boiled water. Will this be bad for a long time? How should i let it cool. The: Laptop Transformer Professional term is called power adapter. Power adapter heat is normal. Power adapter power conversion efficiency can only reach 75-85 or so, in the voltage conversion, a part of the energy loss, which in addition to a small part of the loss in the form of waves, the majority of the way out of the heat The The greater the power of the power adapter, the more energy is lost, the greater the heat of the power supply. The current power adapter on the market are using fire-resistant high-temperature plastic sealed package, the internal heat generated by the plastic shell mainly distributed out. Therefore, the power adapter surface temperature is still quite high, the maximum temperature and even up to about 70 degrees. The following are the same as the " Power adapter heat solution The power adapter heat is unavoidable, but it can speed up its heat to prevent its temperature from rising continuously. 1, the choice of small pressure drop, low loss of switching components, cooling area to be as large as possible, more than 100W switching power supply should generally have a metal perforated shell, or with cooling fan. 2, as far as possible to put the power adapter in a better place to ventilated heat, do not put things like books on the power above. 3, in a higher temperature environment, the use of notebooks, notebook power adapter should be placed in a place not exposed to direct sunlight and ventilation; do not put the power adapter in the notebook near the cooling outlet, or not only the power adapter heat dissipation is not Go out, but also absorb part of the heat.

Q:Maintenance of a household table lamp, found inside the 220v AC to 12v DC, (with a 12v mirror headlight) Transformer has red, blue, black three into the line, plus or minus two output. Ask why is the three lines? In addition to the line of fire and the zero line, what is the remaining root?: Transformer 3 into the line in the red and blue for the line of fire and the zero line (do not have to distinguish), the black line for the ground, if there is no power cord, you can not (empty). General table lamp with a 2-wire power plug, does not introduce the ground. Because the lamp in the circuit, the human body can not touch, not ground is safe.

Q:e in the past with followings already??? I'm just curious I mean Transformers is at 700 mill where everything else is in the 300 mill range which isn't a bad thing but I'm just wonderin'thanksand please give like 5 or more sentences, not a because it rocks: Because most boys/men like toys and things that blow up, plus throw in a barely dressed skank and there you have it!
