Description

The application of the 25MVA/110kV railway balance traction 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 470-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 25MVA/110kV railway balance traction 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 25MVA/110kV railway balance traction 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: Transformer Transformer Principle: The transformer is a high-pressure water (electricity); outlet is a low-pressure water (electricity)! Transform pressure is buck! Reverse can also! Pool to increase the pump Change the high pressure water! Transformers to replace the iron! Like low-pressure water sealed water tank at the bottom of the high-pressure water! Understand it! Haha! I as a lecturer?

Q: What is the meaning of auxiliary transformer, sub-variable and box change What is the difference (in addition to the capacity difference), how to work with, thank you: Is a dual power supply, usually with a large transformer used as a common, small transformer used as a backup, when the circuit with the fault, cut off in use, put on the spare, the overall is a dual power supply!

Q: HELP!! My boyfriend wants to see transformers and he told me I had to study up first lol! He wants me to know who all of the characters are because apparantly its from a comic or cartoon or something? I dunno but can anyone tell me anything about the TRANSFORMERS? I need to know characters and storyline etc. basically just anything u knowThanks lol.: Transformers are from another planet. The bad guys are deceptacons, who are led by Megatron. The good guys are autobots (?) led by Optimus Prime. The movie has actually got good reviews

Q: If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts? Please help, thanks so much!lt;3: You asked the same question before. Here is the only correct answer again. There is actually a phasing to the transformer windings. If you connect them in series with the phases adding (both hit + 12 at the same instant) you get 24 volts out. If you connect with the phasing wrong (one hits +12 while the other hits -12) and put them in series the output will be zero volts (and they might overheat). If you connect them in parallel with the right phasing you will get 12 volts and the amperage will add to give you the sum of their amperage. If you connect in parallel with the phasing wrong you will get zero output voltage (and the danger of overheating). If the transformers do not make their phasing clear put a voltmeter on the output and briefly turn on the primary while seeing if you get zero or the voltage you want. If the phasing is wring swap the wires of one transformer around and check with the meter again. As long as the phasing is correct there is no problem with either series or parallel. A lot of commercial equipment is made with two low power transformers because two smaller ones are often cheaper commodities to buy than one special-order larger one.

Q: Sichuan transformer manufacturer that a best?: Personal point of view: Sichuan transformer manufacturers are the quality of the general! The scale of the larger Chengdu Double Star Transformer Co., Ltd., Chengdu, Xi'an Electric Electric Co., Ltd. to the limited liability company

Q: How to increase the transformer output current: Change the coil winding group, if possible. Otherwise can not change, change the voltage can be.

Q: Exactly what is the storyline of the Transformers. As far back as I know, there were two brother, Unicron and Primus who fought each other because Unicron wanted to suck up Universes. But where did these two come from? Does it even say?: I am a fan but I haven't been able to find that out myself, if you find out let me know.

Q: Can a transformer alone be used for amplifying audio signals ? If yes how ?: Technically No. The transformer will not amplify a signal, however it can be used to make sure you use any signal you actually do have to your best advantage. A transformer is generally used to achieve an impedance match between the signal source and load. For instance if you were to connect an 8 ohm speaker directly to a 1 kilohm signal source, most of the available signal would be dissipated in the source resistance and less than 1% of the signal would produce movement in the speaker. If however a 1k to 8 ohm transformer is used to match the source to the load,up to just under 50% of the signal will make it into useful energy in the speaker. This is a substantial gain in performance of the overall system but is not actually amplification.

Q: !!! I took a cardboard cylinder from a used firework, dug out all the crap, wrapped 160 turns of tinned copper wire on the outside tight and evenly so it is a beautiful solenoid, held it in place with 2 rubber bands. That was the secondary. Then I wrapped an insulated steel wire around a screwdriver shaft 10 times, stretched it out a little inserted a chopstick into this primary and inserted the chopstick into the firework. I then held it all in place with tissue paper and tape and wired the primary up to a pulsed DC circuit which was made of 3.0 volts wired to a steel file which I rubbed the electrode across. The secondary was wired to a current detector but I got no signal! Why is there zero inductance in my transformer and why is there no current at all? It can't even light up a small lightbulb!!: There is a little more to transformer design than this. Your secondary should have used insulated wire (varnished or enamel would do) as even one turn shorting will give problems. Also, you need to consider the magnetic circuit formed by the steel core. It is usual to use soft iron for this as otherwise the hysteresis will be too large. The entire magnetic flux needs to be concentrated into the secondary so you will need to consider the magnetic path. The transformer is essentially just two (or more) inductors, sharing a common magnetic path. Any two inductors placed reasonably close to each other will work as a transformer, and the more closely they are coupled magnetically, the more efficient they become.
