Description

The application of the 63MVA/220KV startup/standby 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 63MVA/220KV startup/standby 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 63MVA/220KV startup/standby 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:1.Is there going to be a Season 4?2.If there isn't,then is there going to be a new Transformers series?: Transformers animated ended last Saturday with Endgame part II. It was ended because of the movie coming out and Hasbro wanted to focus on movie merchandise. There's been some talk of maybe it starting up again after the movie or even a new cartoon.

Q:How do I choose a transformer? The: Select the transformer, you can not choose too large, can not choose too small According to the following method to select the transformer capacity. ???There is a very important data is not provided, is the load at the same time coefficient. Transformer with the actual load and equipment rated power ratio is called the transformer load factor. The concept of the load factor for the load is the probability that the load is used at the same time, also called the coefficient or the simultaneous coefficient, which is the probability of simultaneous use of the device. The total load is 300kw, but they are used at the same time there is a probability that the probability is the load factor. It is impossible to always use at the same time. Of course, you can according to the actual situation to calculate their own, power factor selected 0.80. ??With this formula, s = p * kX / cosφ Transformer capacity s = device rated power p × transformer load rate kx / power factor cosφ = (300 × kX) × 0.80 This is the transformer capacity. ???Do not know what the motor is used under the circumstances, so it can not be calculated, and only calculate the same time after the generation of the formula into the above formula. If the coefficient is 0.9, then the results of about 340 kVA, are used at the same time, that is, 375KVA, consider a certain margin and spare capacity, that can choose 400KVA. In addition to the above considerations, in particular, consider the motor starting current factor, select the transformer more reliable. As far as possible by the big do not rely on small. And the standard capacity of the transformer level 315,400,500,630KVA, 315KVA a little small, 500KVA big and no need. So choose 400kvA it

Q:Want to use in the air compressor, I do not know it?: Can not. Because the main role of transformer oil insulation is not lubrication. Its water absorption is strong.

Q:Hello. I am setting up a 70 volt sound system. It is primarily outdoors, so I have weatherproof horn speakers. I have a 120 watt 70v amp. I also have a 70v 15 watt step down transformer. Now, I want to run 2 horns running at 15 watts rms at 8 ohms on one 15 watt step down transformer. I was wondering, is this safe? I know it works, because I have tried it. But, can it run long term and can this hurt the amp?: I don't think the person doing the first answer understands the open voltage PA type system that you are describing (and I just barely do) but the intention is that you basically can plug in the correctly equipped speakers just like we plug in appliances on a 120 volt line. I don't think what you are describing with the step down transformers works quite the way you say either unless you want lower volume in a specific area.

Q:I have scavenge many transformer, but how do I know its VA rating (in order to utilize it without damage it)For voltage rating, we can measure using Multimeter, but what about maximum capable ampere ? Or we can only estimate by judging size of it ? Would be glad if there is a way to measure other values too !: Do a load test to determine its approximately current rate. You need an AC voltmeter and AC current-meter and a high wattage variable resistor as its load. Suppose its secondary voltage at no load is 5 volts. Now apply the loading until it drops to about 4.8V ,read the current rate.

Q:What are the malfunctions and abnormal operation of the transformer? What is the difference between them and the line?: Transformer failure: can be divided into the tank failure and tank failure. Fuel tank failure: a short circuit between the windings, short-circuit between the turns, direct grounding system side winding short circuit. Outside the tank failure: There is a short circuit between the casing and the lead wire and the ground short circuit (direct grounding system side). Transformer is not working properly: there are external faults caused by over-current, overload, oil level and due to over-voltage or frequency caused by over-excitation and so on. Line fault: phase short circuit (including three-phase short circuit, two-phase short circuit), two-phase ground short circuit, single-phase ground short circuit, transmission line disconnection.

Q:LED non-isolated drive transformer (two windings) calculation method: General non-isolated auxiliary windings according to chip drop VCC operating range. T = 1 / f Dmin = Vout / Vin (max) Ton = T * Dmin Id = Io * 0.3 (0.3 for the ripple current coefficient) Inductor voltage V = Vinmin-Vout-0.6 (Schottky voltage drop) Lmin = V * dt / di If there are problems please go to the big bit of the forum electronic transformer plate

Q:What is the transformer capacity ratio? Capacity than 100%.: Transformer capacity is the power of the transformer, the capacity ratio is the power ratio, such as 1000KA transformer and 200KVA transformer is not suitable for parallel use. Capacity ratio = 5: 1 greater than 3: 1 Capacity than 100% -------- is the meaning of 1: 1 (such as 500KVA and 500KVA, 200KVA and 200KVA and so on. Transformer side by side conditions: ① to participate in parallel operation of the transformer must be the same wiring group. ② the primary voltage of each transformer should be equal, the secondary voltage are equal. Otherwise the secondary side of the circulation caused by overload, heat, affecting the load, and increase the power loss, reduce efficiency; ③ the transformer impedance voltage (short circuit voltage) percentage should be equal, or with load after the load distribution unreasonable. Because the large capacity of the transformer short circuit voltage percentage, small capacity of the transformer short circuit voltage percentage is small, and the load distribution and short circuit voltage percentage is inversely proportional to this will cause large transformer distribution load is small, the equipment is not fully utilized; and small transformer distribution of the load Large, easy to overload, limiting the parallel operation of the transformer with load operation.

Q:I think the power supply to my external hard drive has failed. Is there anyway I could replace the transformer. There is no way to contact the manufacturers as they have the worst customer services ever (Formac). I have emailed them 5 days ago without a reply.: If it's a regular power block type unit with a standard connector, then it should state clearly on it what the voltage and current output is. If you take it to somewhere like Radio Shack, they should be able to find an equivalent for you.

Q:1. 6volts going in a 12:220v transformeris the output 220v or less, formulas, computations 2. 12v going in 12:220v transformer (1 amp 220VA)core loss, copper loss, eddy current loss etc etc3. 24v going in a 12:220v transformer. is the 220v, lost of power in the input,: If the enter is 24 volts, the output would be 440 volts, yet do no longer try this via fact which you will likely dissipate the transformer. you could word any voltage below the rated enter and the output would be proportionately decrease. in case you word 6 volts, you will get a hundred and ten volts out. i wish this enables.
