Description

The application of the 360MVA/63kV main transformer for Hydro power station.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 the 360MVA/63kV main transformer for Hydro power station. 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 the 360MVA/63kV main transformer for Hydro power station, 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: I have a 120v-36v transformer hooked up to a bridge rectifier composed of 4x IN4004 diodes, 2 filter capacitors and a 100k resistor paralleling them as a bleeder resistor. The rectifier puts out the full 50v DC I expect it to, but at the same time the transformer faintly vibrates (you can only really tell if you touch it), and over time it gets quite hot. Why is this? I have checked over my connections quite a few times and I am 99.9% sure its all connected properly.: Since you are getting the correct voltage from the transformer+rectifier+filter, the most likely reason the transformer is heating is that it is has been designed with the least amount of wire that can possibly do the job, and thus the resistive losses are fairly high in the primary winding (the winding connected to 120 V). If you will be drawing a lot of power from the supply, you should ensure adequate ventilation for the transformer for cooling. Most transformers have a strap that can be mounted to a metal case to help dissipate some of the waste heat. If the excess heat is a problem, you might consider upgrading to a higher wattage transformer. Be sure to check the output voltage under load - it won't be nearly as high as when there is no load connected. The vibration may be due to low quality lamination in the metal transformer core, or loose windings, or both. (The transformer core is made up of thin strips of iron that are insulated from each other, usually with a thin lacquer coating. Quality transformer cores will be very tightly laminated.) The vibration/noise is consistent with the apparent low quality of the transformer, but should not be a problem.

Q: Transformer Amorphous Alloy and Silicon Steel Sheet Advantages and Disadvantages: (5) from electrical performance. In order to reduce the shearing amount of the core piece, the core of the whole product is composed of four separate core frames, and each phase winding is set on the two separate walls of the magnetic circuit. The magnetic flux in each box in addition to the fundamental flux, there are three harmonic flux exists, a winding in the two volumes of the core frame, the third harmonic flux in the opposite phase, the value of equal , So that the third harmonic flux vector in each set of windings is zero. Such as the primary side of the D connection, there are three harmonic current loop, when the induced secondary side of the voltage waveform, there will be no third harmonic voltage components

Q: I would like to input DC9V voltage into 12V, 15V multi-channel, how to do the details of the master: DC-DC converter can be used, its working principle is: the input DC voltage through the oscillator into high-frequency AC, and then by the high-frequency transformer boost, and then rectification to get the required DC voltage.

Q: I'll be going to Peru for 2 weeks and I was wondering if I could plug in my electronics over there. I read that they have both North American and European outlets and the voltage is 220 V and 60 Hz. My iPod wall charger and phone charger say 100~240 V (and my laptop charger says 100-240 V) and 50/60 Hz. Would I need to buy a transformer while I'm there so my stuff doesn't get all burnt out?: If the charger/adapter says 100~240V it means you can plug it directly to the wall. Otherwise, you will have to buy a step-down transformer (240V to 120V). While you could buy a transformer at Walmart, Radioshack or BestBuy, I'd recommend buying it at any hardware store in Peru. They tend to be cheaper in Peru by some reason (less than $10). I would also recommend buying one of those plug adapters, since power outlets in Peru don't have a hole for the ground pin (they use 2-pin connectors).

Q: I have a nice little 120VAC to 7.5KV transformer that used to call an air purifier its home, but I'm not sure how to wire it. I have some guesses, but I want to make sure I don't burn down my house so I am hoping to verify them with the help of the yahoo answers community.: Transformers consist of a primary and secondary winding. If you are certain of the AC input side (and the fact that they are black and white suggest you are) then the green and red wires are the secondary and would produce the 7.5kv AC output. Neither of these wires can be connected to ground as that would short the transformer and more than likely fry it,trip a circuit breaker , cause a fire or all three. Secondary windings with more than two connecting wires would indicate a transformer that can be tapped, which means that various voltages can be obtained depending on the combination of the output wires. 7.5 KV is a very dangerous output and if you are using the transformer outside of it's intended device, a fuse on one of the AC leads would be an absolute necessity.

Q: Can a transformer alone be used for amplifying audio signals ? If yes how ?: Transformers are AC (alternate current) devices and if 60 Hz is supplied to the primary windings 60 Hz will be produced at the secondary terminal. The transformers transform voltage and current at the primary to voltage and current at the secondary by magnetizing a mass of iron in their cores. The magnetic cores may not respond efficiently to very high frequencies (transmission frequencies) but might respond to audio frequencies (loud speakers employ magnets and coils of wire). If a suitable audio signal was applied to the primary coil a transformer might be used to step up or step down the voltage of the supplied signal while reversing its phase, however power (P EI) would remain nearly constant.

Q: Hi there.I have purchased a Stepdown Transformer so i can use a Record Cleaning Machine I am buying from the U.S.It uses a powered suction unit to clean the record.All transformers for use with American equipment have 110v output, but i think your equipment is usually 120v.in I have been told that there is nothing to worry about as 110v out on the transformer is enough to power the equipment connected to it .Our AC output in Australia is 240v but we can use any voltage from 220 to 250. Therefore 110v should be enough.can anyone clarify and tell me it should be ok.Thanks a lot in advance.: Electrical appliances are designed to tolerate the range of voltage. Here in the USA the terms 110 and 120 are used interchangeably as are 220 and 240. Good luck mate!

Q: I was just curious if they ever had an episode or something where somebody manipulated a captured transformer and was able to control it or something, or something that turned someone into a transformer. far fetched ya but god knows the stuff that's out there these days, so I was just wondering.: Transformers original series, season 3, Only Human - Criminals get their hands on four Autobots and remove their minds, turning the bodies into piloted mecha. Transformers IDW Comic - Sunstreaker is captured and bootlegged, copies of his body being controlled by humans while they use his original mind as a sort of coordinating system. Transformers Animated - The villain Headmaster's whole schtick is to cut the heads off Transformers and take over their bodies.

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.: If you plug in a 50W fan into your 1600W transformer, it will only draw what it needs + a little more for losses. You are right about the losses that you feel/see with this transformer. Some of the voltage conversion is lost as heat as a transformer is not 100% efficient. (As a matter of fact, no energy conversion system is 100% efficient as stated in the 2nd law of thermodynamics). A transformer typically is pretty efficient; usually above 95%. So you would be drawing maybe an extra 1 or 2 watts, not 10, with your fan. When nothing is plugged into it, it should draw some minuscule power due to losses, but not very much and definitely not 1600W. I personally would not let it be plugged in all the time. If it of a cheap or poor design and not UL (Underwriters Laboratory) or other agency rated, it could short out and cause a fire. But that is just my anal-retentive nature
