Description

The application of the 150MVA/345kV three phases self coupling generator interconnection transformer.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 150MVA/345kV three phases self coupling generator interconnection transformer. 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 150MVA/345kV three phases self coupling generator interconnection 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q:I am an avid stop motion animator, and I have been looking for Transformers toys to buy and animate. I have one, Deluxe Class Cliffjumper, and he's really great, pretty much the same as Deluxe Class Bumblebee. He works very well for stop motion. He transforms great, he looks cool, he's got good feet, he has stiff joints, and is very flexible and poseable. But I've been looking for another Transformer toy that can do the same job. So far I've bought two, and they have not been the same quality. I bought Deluxe Classes Barricade and Bonecrusher, but Barricade was too flimsy and Bonecrusher is too top heavy with terrible feet for poseability. Anyone familiar with the Transformers toys that could give me any ideas for the better toys for animations? (Under $40, please.) Thanks!: Do you mean the monster will say rates as he kills, or do you mean the full soundtrack would be rates. So, if he have been to have a communication, all of his communication may be sampled from different video clips? If it is the later subject, then i might propose getting Jack Nicholson video clips. His voice is so creepy and he has made maximum of flicks, you have have been given to be waiting to come across something you will need. If it is the former (the place he's in basic terms quoting type video clips), i admire: Wait'll they get a load of me! Jack in Batman right this is Johnny! Jack interior the Shining you are able to not shield the fact! Jack in some reliable adult males How a pair of superb interest of chess? the pc in conflict video games hi, Clarise.

Q:A transformer has a 100-turn primary coil and 1000-turn secondary coil. The primary is connected to a 120-V AC source and the secondary os connected to an electrical devic with a resistance of 1000 ohms.what will the voltage output of the secondary be?what current flows in the secondary circuit?what is the power in the seconday coil?what is the power in the primary coil ?what is the current drawn by the primary coil?: If the secondary has 10 times as many turns, it will multiply the voltage by 10 times. 120 VAC x 10 1200 VAC Use Ohm's law, EIR for the current. Voltage Current times Resistance, Volts Amps x Ohms 1200 I x 1000 I 1.2 Amps Power in Watts E x R (Volts x Amps) 1200 V x 1.2 A 1440 Watts For a 100% efficient transformer, the input power matches the output power. In real life, a bit more power goes in than comes out. That's why the transformer gets warm. For this problem, with a perfect transformer, the input power will be 1440 Watts. That makes the input current 12 Amps. What they want you to see in this exercise is that the transformer, because it has a 1:10 ratio in the windings, is that the secondary will have 10x the voltage and 1/10th the current. The primary will have 1/10th the voltage and 10x the current. And they want to make sure you understand the power in matches the power out.

Q:Transformer voltage ratio and current ratio.: In theory, the transformer voltage ratio is equal to the turns ratio, the current ratio is equal to the number of turns inversely proportional. There is actually a slight difference.

Q:how the electronic transformer work?: Ballast Transformer

Q:Power transformer parameters: B. Transformer efficiency: In the rated power, the transformer output power and input power ratio, called the efficiency of the transformer, that η = (P2 ÷ P1) x100% where η is the efficiency of the transformer; P1 is the input power, P2 is the output power. When the transformer output power P2 is equal to the input power P1, the efficiency η is equal to 100%, the transformer will not produce any loss, but in fact this transformer is not the transformer transmission power always produce loss, this loss is mainly copper Loss and iron loss. Copper loss is the loss caused by the transformer coil resistance.When the current through the coil resistance heat, part of the energy into heat and loss.As the coil is generally wrapped with insulated copper wire, so called copper loss. The iron loss of the transformer includes two aspects: First, the hysteresis loss, when the AC current through the transformer, through the transformer silicon steel wire magnetic field its direction and size changes, making the silicon steel sheet internal friction, release heat, Part of the energy, which is the hysteresis loss. The other is the eddy current loss, when the transformer work, the magnetic core lines through the line, and the magnetic lines perpendicular to the plane will produce induced current, because the current self-closed loop Circulation, and into a spiral, so called vortex. The presence of eddy current heat, energy consumption, this loss is called eddy current loss. Transformer efficiency and transformer power levels are closely related, usually the greater the power, loss and output power is smaller, the higher the efficiency, otherwise, the smaller the power, the lower the efficiency.

Q:Does the production transformer require 3C certification? Does the country have any specific requirements?: In general, the production of power transformers do not require 3C certification. The state does not have specific requirements, but if you want to tender, is certainly qualified, the most important is: the state authority of the type of test report (often: National Transformer Quality Supervision and Testing Center (Shenyang)) and model registration Certificate, then ISO9001

Q:Hey!I Love Shia Labeouf I Was Wondering If Transformers Was A Good Movie I Haven't Ever Got A Chance 2 Watch It. Is It Worth Watching? These Are Some Of The Films I Like.Pirates Of The Caribbeanthe Dark KnightSpider man 3 Home Alones Mean GirlsThnxxP.S. I Heard Theres Going 2 Be A Transformers 2! D: Transformer is honestly the sickest movie of all time. Are you kidding me. I watched it at least 7 times, and I had to buy the movie when it first came out. Only movie I have ever bought, and I didn't even like transformers that much growing up.

Q:I want to multiply current 10times for a second or two. So, is there any easy way to do that without using a high power transformer?Thanx.!: Current can be multiplied 10 times when using a current transformer with a ratio of 10, such 50/5 amperes. Donut type CTwith a burden of 15 VA.

Q:I am looking for a 220v transformer with these secondary voltages: 2x13v, 1x9v, 1x3vIt has to be at least 20va.I cant find this anywhere :/: This is an unusual requirement. You may need 2 or more transformers. Do you really need the 2 voltages, or could you develop some of the lower voltage by using DC voltage regulators (if the lower voltages are used for DC)?

Q:500KW load should be installed how much transformer?: Mainly to see what the load, if it is home lighting electricity, according to the 0.9 power factor and 20% of the margin, you need to be equipped with 500 / 0.9 / 0.8 = 694.4, you can take 750 kilovolt capacity can be. (Consider the future expansion of another operator), if it is with the motor and other load-based, due to power factor and start the current reasons, at least 900 kVA more appropriate. If the drive is more than 200 kilowatts, the starting current is very large, you need to put a larger margin or the motor using the buck mode (increase the investment cost).
