Description

The application of 32MVA/220kV main 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 32MVA/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 32MVA/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: What is the maximum current of the 800KVA transformer? What is the current? Is how to calculate, ask you master: This type of capacity of the transformer for the distribution transformer, that is, step-down transformer. Voltage combination to 10 / 0.4 for multi-purpose. Transformer high side current 46.19A, low side current 1154.73A. Rated capacity = 1.732 * rated voltage * rated current

Q: If load loss of a transformer at full load is 100kW, the load loss at 50% load will be a) 50kW b) 75kW c) 25kW d) 100kW. i think its 25kW because load loss is inversely proportional to the square of loading percent. kindly explain . is it right.: I'm guessing load loss is the same as copper loss, which is due to the resistance of the wire in the transformer. This loss is (I^2)(R wire) so the answer is c) 25 KW The current is 50% at 50% load, I^2 0.25

Q: As we switch off an appliance at home, the power supply is cut off.when we switch it on , the power is on.How does the transformer regulate /manage as per our requirement: A transformer simply changes one voltage to different voltage. There is some voltage change due to I*R in the transformer, but the transformer doesn't regulate the voltage.

Q: i need a little help with my homework. if you bank three single phase dual voltage transformers in a delta connection for the primary and do the same for the secondary, do the kva of primary add together or do the kva stay the same because it is connected in delta.it's a 2:1 480v - 240v each transformer is 5 kvais the total kva when connected in delta 15 kva or 5 kva and do you use the formula Pa line current times line voltage times 1.73 to find the rated load current.thanks in advance: Delta connection it's mean you give 480 V 3 phase, and output 240 V 3 phase. So the total KVA in delta is 5 KVA and the formula like you said. Pa I (current) x Volt x 1.73 (three phase) x cos Q (Cos Phi).

Q: How much W?: 1. And your material related. If the good material, high frequency loss is relatively small. You can do 15W. For example, 200KHZ switching frequency. 2. If you are on the general market, the maximum control in the following 10W. Switching frequency 50KHZ.

Q: This transformer outputs AC or DC: The transformer on your diagram is the power frequency isolation transformer. Input communication, the output is also communication. If you encounter a transformer with DC output, it can only say that it has pre-installed rectifier components rectified and then output, but this situation is almost no, mainly practical and electrical safety.

Q: I am in a verge of purchasing a house that is located very adjacent to a polyphase transformer. I hear of the stories that say about the adverse effects that are caused by these transformers to various electronic goods that are there in the house. Please clarify.: Poly-phase transformers which are merely 3-phase transformers don't really cause anymore interference than any other transformer. If the thing was up against your wall, then maybe it would mess with radio or cell phone communications, but really your main interference concerns would be if you were near high voltage transmission lines. Why not ask the previous owners or neighbors in the area if this transformer has interfered with their electronics.I doubt it.

Q: I know that someone made a transformer movie. But wouldn't DBZ the movie be a lot better!?!?!?: If DBZ is Dragon Ball Z, the answer to your question is no. I say this not out of opinion but out of America's taste in entertainment. America as a whole doesn't tend to enjoy Japanese style entertainment. Transformers is a movie based on aliens and robots. DBZ is mostly based on magic and such. America likes stuff that they can grasp and make sense of.

Q: Rated capacity of three-phase transformer S = √3 * U * I: So, when calculating the three-phase load, U is the line voltage, and I is the line current. S = 1.732 (root 3) UI. S = 3UI. Where U is the phase voltage and I is the phase current. S = 1.732UI where U is the line voltage and I is the line current. Two methods, the same result.

Q: Hello, I'm new to electronics and I would like to know how is the current affected by a step-up or step down transformer. EX: Lets say you have a pure AC wave (60Hz , 25vac, 5A) hooked up to a 1:4 power transformer with a current rating of 10A, What will the voltage and current be and why? Thank you!: ok, so if you use the equation Fma you can isolate the force on the circuit by the power transformer. !st) F60*2pi3456 2nd) you plug it into the charge formula and get 32.086C, which is your answer.
