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: What is the SN on the transformer? What is the difference between it and the actual power of the transformer?: SN is the rated capacity of the transformer, the capacity is also called the apparent power. It represents the maximum power that the transformer can transmit in the rated state, that is, the maximum power that the transformer can transmit when the power factor is 1 is SN kW. Transformers are only used to transmit power, in addition to their own no-load loss and load loss, the power does not consume. The actual power it delivers depends on the load. Transformer: Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric transformers, rectifier transformers.

Q: I have some questions about some of the transformer toys1)Why is it that the stores never put out some of the action figures I'm looking for like Ironhide and Starscream2) Why am I seeing a bunch of voyager class Ratchets and deluxe class autobot wheelie on shelves in every store i go to that sells transformers stuff3) Why do stores put on there shelves either a bunch of leader class optimus primes, or a bunch of leader class megatron and there's barely any jetfires 4)where do you think is the best place to buy transformer figures, toy R us, walmart, target, ETC, but don't say internet5) this last one is just your opinion and its what do u think is the worst figure you have or is in your collection and tell me why, for me its voyager class the fallen, because getting him was really hard and he's not even worth being that rare.So those are my questions, i hope you can answer them all and thanks: Sorry Koda you're incorrect! they do no longer remodel into robotic, regrettably. the only one that combine and have a robotic and alt mode are the legend figures as for now and overload will join the mixture interior the legend mixture. desire it enables. P.S.- the image of the hyperlink is the ideally suited classification that fee $a hundred

Q: I have a doorbell that quit working. I don't know how to tell if it is the bell or the transformer: Take the cover off the bell and see if it runs on batteries. If it runs off a transformer you can touch the transformer it should be warm. If it is take the button off the outside and touch the 2 wires together if the bell works its the button. Its only 24 volts you won't get hurt.

Q: hi guys can any of you give me advice on wot i need 2do on removing and replacing a faulty line output transformer on a rear veiw projection tv as i have the part and the local tv shop wont fix it 4 me.wot would be the best way to discharge the power from it first and could i jus cut the 2 wires on the old 1 and use connector blocks to connect the new 1 in would this be ok to do or do it need to soilder connected on?. and is there any adjustments that would need to be done to the set when i have it installed be4 i turn it on any help much appreicated: Solder the joints!!!!It is OK to use the old connectors!!!! Be sure that the power of the new transformer it is the same with the power of the old one.

Q: I heard that a transformer is like a ratio device for amps and volts, but I know there must be more to it. How exactly does it work, and what happens when it doesn't have enough current, but enough voltage?: reliable question. to respond to your question, no it wouldnt paintings like that. Transformers substitute AC voltage not DC present day. the way it truly works is that the AC enter creates a magnetic container in the different edge, coming up present day and voltage. in spite of the shown fact that it truly is proportional to the windings on each and each coil. in case you wind one coil on the enter to each 5 on the output, you have created a a million:5 transformer. you put in x voltage and get out 5x. before everything this appears like unfastened means. yet you're actually not elevating present day and voltage. certainly means would desire to stay the comparable. means volts * amps. hence, in case you enhance the voltage, you shrink the present. The strobe mild circuits interior cameras substitute a a million.5V AA battery into approximately 1000V. the present in spite of the shown fact that, is plenty smaller.

Q: KW how to know how much transformer?: You said KW, it should be refers to the active power of the. Select the transformer depends on the nature of your load, and what type of load, such as emotional load, or resistive load? If it is purely resistive load (very little), then the transformer capacity to choose the same as your load can be, if it is emotional load, then according to the formula S × cosφ ≥ P can be. Calculated after the election can be selected transformer, the general will leave a margin of more than 5%.

Q: Transformer and the middle of what is the difference: Often referred to as the transformer is the frequency transformer, is used to change the size of the AC voltage electrical equipment. It is based on the principle of electromagnetic induction, with the same frequency, between two or more windings, the exchange of AC voltage and current to transmit electrical energy of the static electrical equipment.

Q: In the transformer load calculation to be calculated when the fire pump: And then calculate the capacity of fire, this time part of the commonly used load fire exit, all the fire load plus fire when the important load, is the fire state capacity. In accordance with these two states, the larger capacity to select the transformer capacity! Phone typing is not easy, please adopt ~

Q: 1. a district 800 + a layer of 500mm2 shopping malls should choose how much capacity? 2. A 315kva transformer has been for a district 600 households electricity, ask there is a 70 households can access the transformer?: In the actual choice, should adhere to the "small capacity, dense point" principle Distribution transformer location should be located in the load center, and the power supply radius of not more than 0.5 km. Distribution transformer load rate between 0.5 to 0.6 the highest efficiency, At this time the capacity of the transformer is called the economic capacity. But if the load is relatively stable, then the continuous production of the situation can be selected according to economic capacity transformer capacity.

Q: Who knows the density of the transformer oil is how much?: 25 # transformer oil: 895kg / m3 877.6kg / m3 45 # transformer oil: 895kg / m3 879.0kg / m3
