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.

Q:Can you put dolar energy through a step-up transformer to create more energy?: CAN YOU CONNECT A SOLAR PANEL TO A STEP DOWN TRANSFORMER?

Q:10KV distribution transformer how to calculate the tap voltage: 10kV distribution transformer tap voltage can be Ue ± Ue X% (X is the percentage of each range of adjustment). General distribution transformer tap adjustment range of Ue ± 2 × 2.5%; tap for 1 - 5, the tap voltage is calculated as follows: 1 ----- 10+ (10 x (2 x 2.5%)) = 10.5 kV 2 ----- = 10 + (10 x 2.5%) = 10.25 kV 3 ----- 10kV rated voltage, 4 ----- = 10- (10 x 2.5%) = 9.75 kV 5 ------ 10- (10 x (2 x 2.5%)) = 9.5 kV Transformer tap on the high side, according to the needs of the low side to adjust the high pressure side of the tap position. If the low voltage side of the low pressure should be raised to 4 or 5, and vice versa to 2 or 1 up. Because the adjustment tap is used to change the transformer ratio. In the case of a transformer with a rated voltage of 10 / 0.4kV, its change ratio K = U1 / U2 = 10 / 0.4 = 25; when the secondary voltage is low, if the split is set to 4, the position K4 = U1 / U2 = 9.75 / 0.4 = 24.375, the primary voltage is still 10kV secondary voltage = 10 / 24.375 = 410V. Increased secondary voltage. In fact the adjustment of the split is adjusted by the number of turns of the coil, the change in the ratio and the number of turns of the secondary coil is constant. To reduce the secondary voltage, increase the number of turns of the coil.

Q:I want to make a simple flyback transformer driver. I have a flyback transformer of samsung CRT monitor. Can anyone give me a complete design of flyback transformer's pin. What are the required components. Please give answer in detail.: These transformers are designed for TV or monitor line frequency. They use a square wave drive at the line frequency (15625Hz or more for a monitor) The on time is around half the duration of a cycle or more, so 32us for 15625Hz. The driver is a switch, it is on for this time. The current builds as a sawtooth (ramping) current in the inductance of the winding during this time. The design of the driver switch needs to take into account ratings are in the safe operating area (SOA). This means the rate of change of voltage and current, as well as the instantaneous V * I must always be within ratings. It means that the switch should be rapid, so there is minimal time spent in the transition off to on and on to off. There usually needs to be a snubber network to control voltages across the transistor. The pin connections of the transformer? The links below show how to do it basically. It also shows how to check out and identify the windings you need, and also to verify them, using the schematic of the original device if possible. Tracing wires on the circuit board can help too, to identify the primary. You only need to identify 4 pins usually. There are some safety issues here. Some have small internal capacitors that store energy. This can give an unpleasant shock. It could be around 0.2 joules or more because of the high voltage. I am not sure what sort of a hazard this might be, but I wouldn't take it too lightly or use it to shock yourself or others. I assume you are using a 12V DC supply @ a few amps current to power this.

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:How to make a current transformer more linear? Except change the core.Thank you!: Ideal linearity is reached when B and H are linear. Use air as medium. It may give less output but linearity will be perfect!

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 from what kind of source, into what kind of load? Does the load take AC or DC?? What voltage does it need?? Why do you have to multiply the current? You can get clever with things like bucking switcher supplies to take 120 volts in and get 12 volts out at about 10x the current, but if your load isn't DC it doesn't help you. Edit:? 30 A @ 8 V isn't much, just 240 watts.? You can probably get this out of an old computer power supply; just re-wind (or add an extra winding in series with) the 5 volt winding on the toroid transformer to get 8 volts.? You may have to get fancy to get it to stay on (lots of the newer supplies want to be loaded, and want special signals to run) but with common supplies putting out 400 watts and more you should have no trouble.? The only issue is that you won't get 50 or 60 Hz, but since you didn't say your load has any particular frequency requirement I'll offer this as a possibility.

Q:If calculating the efficiency of a transformer with different frequencies,how can the frequency be altered? For the experiment the voltage applied will have to be constant, is this still possible? or what quantities will be kept constant? and which will be measured to calculate the efficiency? using PVI to then use %(Pout/Pin)*100 would mean measuring current and voltage, is this the best way?: properly no rely what engineering considerable you elect, you may desire to take Calculus a million 2, Matrices, Differential Equations, Chemistry a million 2 with labs, Physics a million 2 (Electromagnetism). you do not easily declare your engineeing considerable till the top of Sophmore 300 and sixty 5 days in college. Junior 300 and sixty 5 days is once you would be formally enrolled in a considerable. once you word for college and choose a considerable, you at the instant are not easily enrolled in that considerable and you will nevertheless choose any considerable you prefer. they merely ask what considerable you have an interest in to verify you're taking the mandatory situations on your first 2 years earlier stepping into your considerable in Junior 300 and sixty 5 days. interior the 1st 2 years of taking chemistry, math, and physics, you may additionally take Intro to engineering(CAD), and a brilliant form of engineering classes and electives like Statics, Dynamics, power of fabric, Thermodynamics, Into to electric powered Engineering(Circuits), C++, or Fluids. those classes will help you make certain what direction to circulate in direction of. based on your description, you desire Mechanical or business Engineering. the two deal in convalescing performance of goods, machines, and approaches. the two have numerous math. the two prefer expertise of Physics and the two require you to be good in difficulty fixing.

Q:im doing a power point and i want to know all i have is that it got started in 84', but who owned it at first and who ownes it now and is it a product? but basically i need a site or a person to tell me how it got to now and i need a site that has nice pics of the first transformers to 2009: Yep, it replace into an 80's comic strip placed out with the help of way of the Hasbro company company company,(who additionally advertised the everyday GI Joe toys and cartoons). The exhibits have been long working commercials for the ever evolving line of toys. The Transformers have been the form till Hasbro have been given right here out with the previous Transformers action image (anime) which pissed each and all the fams off by using fact of certainty they killed off Optimus precise and then dwindled the numerous characters into obscurity with the objective to sell their new line of robots. you will are available the process most of the previous episodes on youtube.
