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: 50 What is the actual power of the transformer? Is 3 phase 50 or 3 together 50: If it is three-phase transformer, the power of the brand name is the sum of the power of three phases

Q: I'm a beginner in electronics ,I have a big , old transformer (I think it is AC) , only supplies + current. (36 Volts)I also need - current to drive an amplifier.So i think it's an AC to DC converter i need. (It's just a guess , i don't really know.)How can i achieve this ?Note : If you need additional details , please include how i can get that detail , just in case i don't know.: Transformers do NOT supply only + current, which I assume you mean as positive voltage, DC. So this is a power supply, not a transformer. Yes, you need an additional 36 volts DC power supply, and you would connect it as a negative supply, ie, connect the + output to your common or ground, and the – output would then be –36 volts for your amplifier. As to how, buy one or make one. Search google for 36 volt power supply. You will need to know the current requirements also.

Q: For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?: the adapter contains a Transformer to drop the voltage and a rectification circuit to convert from AC to DC to smooth the rectified voltage. the transformer has only a small amount of power consumption when the secondary coil has no load, Although the winding resistance of the primary coil is a constant the current flow through it is restricted by the magnetic field. the rectification/smoothing circuit is likely to cause some load even if there is nothing connected to the outlet of the transformer.

Q: if the transformer converts 240v ac to 8V ac, ratio 30:1 then it should step up the voltage by the same ratio, i.e, 15V ac to 450v ac.but it's not the case !!: It will, but you have to realize that the series resistance of the primary (which is now your secondary) is getting in the way. I am going to guess that this is a very small transformer, capable of one or two VA at most. The rating is a little tricky too. A 240V-8V transformer puts out a significantly higher voltage, maybe 20-30V, with no load. It's rated at 15V because under a load, with magnetic and resistance losses, the effective turns ratio is lower. Used in reverse, the opposite problem exists, because your actual turns ratio is much higher than 30:1. Edit: If it wasn't for silly ideas a lot of inventions wouldn't have been made. The secondary probably doesn't have enough turns to provide adequate self-inductance at 240 volts. It would just act like a short and burn out. There is also a possibility that there is not enough dielectric strength between adjacent windings or the frame to prevent arcing, but most transformers are designed to withstand thousands of volts so this is less likely. If possible, I'd recommend trying lower voltages (perhaps 8V from another transformer), and measuring the current with the primary (now the secondary) open. Put a load resistor in there to start just in case. If you're drawing more than a few milliamps, don't try hooking it up to the mains.

Q: This transformer outputs AC or DC: If you have 220V output voltage, then the peak voltage of the waveform is 220 * 1.414 = 311v, then your rectifier at least reverse voltage of not less than 400V, then the voltage is not more than 400V The Look at your transformer current, if the full load current is 7A, then your rectifier load capacity should not be less than 10A. So the main consideration is the rectifier voltage and current these two aspects.

Q: i rememeber when i was a lil kid i used to watch Beast Wars on friday nights. I think it was back in 2000 or so. It was pretty cool too; as opposed to transforming cars, etc, there were transforming animals. also there werent any humans.imo the new transformers animation sucks, though the movie was greatim sure Beast Wars and Transformers are related because they used names like Megatron and Octomus Prime (sp?)so yeah. what happened to Beast Wars?: What rely isn't what occurs on the tip of the day, this is what occurs on the tip of the universe. Scientists say the universe will fall down right into a chain of black holes, and because time does not transpire interior black holes, that could be the tip of the universe. yet another time, the Bible is shown by technology. Does that sound rather like, oh, i don't comprehend, HELL!?

Q: Hello,Recently, my air conditioner broke and I hired a man to come fix the machine. Unfortunately, he did not help my situation and possibly made it worst.Initially, he informed me that my transformer was broken and so said that it needed replacement. However, when he replaced the transformer, both the transformer and the circuit board blew out. Now, he's making me pay, not only pay for his services, but also for the two additional parts. My question is: Is is possible that the circuit board caused this issue? Or did he mess up on the wiring and blow both parts out, by mistake?I just need to know, so I don't pay for something, originally not of my cause.Thank-you.: It's possible that the circuit board developed a problem that caused the transformer to fail. So when he replaced the transformer, the defect on the board may have caused the new transformer to burn out. It's not too unusual for things like this to happen, so I wouldn't blame him right off the bat. The next step might be to have him (or perhaps another A/C service person if you're confidence in this first guy is shaken) replace both the board and the transformer prior to powering up the system.

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.: submit a schematic and a few concepts on the transformer. Circuits with transformers continuously have some inductive power that could desire to be dissipated whilst the transistor(s) turn off. this could reason extreme voltage spikes which could unquestionably injury a transistor (whether the case isn't warm). you may desire to guard in comparison. A 2N3055 is an quite sluggish gadget and not very proper for top velocity switching.

Q: Can a european power outlet handle a 5000 watt power transformer?: No. Most are on 16A circuits, which can practically handle 3KW or so. UK recepticals are limited to 13A, so will be less. You might be able to use an electric stove outlet, if you know how to use one safely.

Q: I have two-way transformer (120Vlt;240V) that has a surge capacity of 2000W and a continuous capacity of 1600W. The transformer is plugged into my wall socket and is, on its output side, attached to a power surge protector that leads to six separate sockets. There are periods where not all six sockets are in use - in this specific case, the only appliance is a 50W fan - and my question is, does the transformer still eat 1600W off my meter and waste most of it as heat, or is it nice and intakes maybe only 60W and inefficiently converts it to the required 50W? If the company/model comes into question, I can only say the transformer is of Taiwan origin - the company logo is a 'Z' with small D intersecting the two parallel lines of the former letter, all against a blue background - and has a model number of TC-2000. Many thanks.: the thought is sure and NO. sure, by way of fact a transformers considerable coil has a undeniable resistance. Wattage used is a function of voltage cases modern-day. on the grounds which you recognize the enter voltage is a hundred and twenty V, in case you are able to degree the coil resistance you are able to calculate the present used. Multiply modern-day cases voltage and you get wattage. although, the character of a transformer is extra desirable than basically a trouble-free function of Ohm's regulation which you would be able to seem up on the internet. there is yet another function of a transformer that could desire to be further into the equation, and that i'm not an authority on that. although, this extra ingredient is talked approximately as Inductance. that rather skill that reckoning on the burden of the output, the enter wattage will replace, however not heavily. Suffice is to assert that a transformer it is plugged into the wall yet isn't working something DOES proceed to apply power. you are able to tell this by way of fact the transformer would be warmer than if it weren't plugged in in any respect. this is going on on the grounds which you're changing electric powered modern-day into warmth - you're making use of electricity. on your case, making use of a decrease wattage bulb (this difficulty LED) you will use much less power, yet will in no way be saving a form of electricity. If going green is the objective, you would be extra valuable off making use of a hundred and twenty v LED lights OR a low voltage device it is designed around using LED. to easily set up LED will consequence in little or no decrease fee rates at an exceedingly huge fee. LED lights isn't decrease priced. solid success. :)
