Amorphous Alloy Oil-immersed Transformer
Introduction of Products
Amorphous alloy isderived from iron, boron and other elements which rapid cooling down to mouldin order to arrange its atoms disordered. Compared with silicon sheets, the permeabilityof amorphous alloy is high, the no-load losses and current is lower, and moreoperation charges can be saved. Meanwhile, its heat is low,and it has good stability to make its working lifelonger.
Performance Characteristics
1. Saving power: The no-load losses reduce byabout 80% than that of S9 series.
2. Reliable: The capability of anti-shortcircuit is strong.
3. Protecting environment: Its noise is lowand it can decrease the discharging quantity of carbon.
Structure Characteristics
1. The core adopts three-phase five-limb and HV winding adopts D connection,which eliminates the three fluxes and three-harmonic electric potential anddecrease eddy current loss and temperature caused by leakage. Meanwhile, the steepnessof impulse voltage is reduced.
2. The coil takesthe shape of rectangular, and use conductor tensioning device to wind. Itadopts shaping, press mounting and other technique measures to make the outsidedimension of coil come to design requirement. And that HV coils wind outside LVcoils improve the strength of coil and the capability of anti-short circuit.
3. There is no oilstorage tank and moisture absorber on the oil tank. The transformer oil doesn’tcontact with the air and the expansion of oil depends on the elasticity of corrugatedplates to compensate. This can eliminate maintenance and improve working life.

- Q:I bought a 110 v AC transformer to run an item that requires 24.5 v DC. the transformer I bought is 110 v Ac to 30 v DC. can I put a rheostat inline (at the dc end before the unit to be powered) to adjust the voltage output ? and if so, Where do I find one?
- Not practical. Sure, you will get a small amount of output, but only as long as you keep moving the rheostat. The efficiency will be in the few percent range. Not counting the mechanical effort to move the rheostat. You have a lot of questions about this. I don't know your goal, but for a practical DC transformer, this will not work. It has zero chance of success. The only practical way is to use a transistor to chop the DC into AC at the proper frequency. This now begins to look like a DC-DC converter. .
- Q:I have a 240v-5v transformer for recharging, and it makes an annoying very high-pitched squeaking noise. What causes the noise?
- Normal transformers with iron laminated cores operate at 50-60Hz (50-60 times a second), but transformers in modern cell-phone chargers and PC power supplies require a higher power than would be possible for the given size restraints. A 240v to 5V @ 1A 50-60hz transformer would be the size of a deck of cards and would weigh several kilograms, but if you replace the core of the transformer with a ferrite material (powdered iron) and switch the primary winding at high frequency, say 20Khz or more (20 thousand times a second) the size of the transformer shrinks to the size of a small coin. The ringing sound you are hearing could be caused by several things: 1. It's operated at a near-audible frequency, like 19Khz (not very likely) 2. It's under very high load condition and it's struggling to meet the power requirements and as a consequence the duty cycle of the PWM has increased which can make a chirping sound. 3. It's defective or dying, and it's having a hard time regulating the output voltage and it's excessively modulating the PWM. 4. You are young and young people have better than normal hearing in the higher end of the frequency range and you might be hearing a harmonic of the higher than audible drive frequency. Hope that answers your question :)
- Q:describe a stabilised transformer
- I'm only guessing that you may be reffering to a transformer that is equipped with taps on the windings that allow for +/- 10% votage changes on the secondary to maintain a fixed voltage when the input voltage (primary) varies or the load on the secondary varies. Thus stabilizing the voltage to the load. These are called TCUL (tap changeing under load) or LTC (load tap changing)-the more common term-transformers.
- Q:Audio output transformer
- no. there is no such thing as a generic output transformer, each is sized according to power handling and specific tube/transistor characteristics. some even have additional windings to facilitate inverse feedback, gain leveling, or similar circuits. historically, tube power amps were designed according to the transformer selected because that affects many design parameters. considering the pervasiveness of transistor amp designs that do not use an output transformer, you would be hard pressed to find one in most toys or other electronics.
- Q:I know that before the 2007 release of transformers and this years sequel there were various animated tv series and comics. I just want to know what the live action movies are actually based on. Like are the movies just real life portrayls of the the animated story line? Or are they original plots just based on the ideas of autobots, decpticons and there home cybertron?If the plots for the movies are based off the comics of series (like the x men movies) what could be the possible plot for the 3rd installment of the film franchise?
- The Transformers film was based on the first film, The Transformers: The Movie (1986) which was based on the animated series. Transformers are alien robots of a popular Hasbro toy line and its spin-offs. The Transformers began with the 1970s Japanese toy lines Microman and Diaclone. The former utilized varying humanoid-type figures while the latter presented robots able to transform into everyday vehicles, electronic items or weapons. Hasbro, fresh from the success of the G.I. Joe: A Real American Hero toyline, which utilised the Microman technology to great success, bought the Diaclone toys, and partnered with Takara. Jim Shooter and Dennis O'Neil were hired by Hasbro to create the backstory, the latter of whom christened Optimus Prime. Afterwards, Bob Budiansky created most of the Transformers characters, giving names and personalities to many unnamed Diaclone figures. The primary concept of G1 is that the heroic Optimus Prime, the villainous Megatron, and their finest soldiers crash land on pre-historic Earth in the Ark and the Nemesis before awakening in 1984.
- Q:I am building a simple circuit and was wondering what is the difference between a coil and a transformer? Also, in my circuit I have a generator. My generator is made up of a coil and magnets. I would like to know do the amount of turns my coil is determine the power of the generator? When I select the gage wire I am going to use we that determine the amount of volts and current I can gain from my generator?
- A transformer is nothing but a magnetic core on which two isolated coils are wound. Power of generator depends on many factors 1. Size and strength of magnet 2. Size and magnetic properties of iron parts 3. Rotating coils, speed, diameter, length. Gage wire is chosen based on volt / ampere considerations, not the other way.(gage does not decide voltage and ampere of the generator)
- Q:I'd recommend a big Transformers fan for this please. So I have a Transformers series that I'm working on for fun, and I want an awesome name for it. It has Unicron in it and the Autobots and Decepticons team up to take him down. A name for that part is Cybertron Alliance. But I also need a name for story with events that take place before that, when the Bots and Cons were at war. Please help!
- You can't do that, you didn't make Transformers. Michael Bay would have asked could he add some of the characters into his movie. Like they would have asked J.K Rowling could they do Harry Potter Movies.
- 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.
- Q:440 kv(Primary side) and then at the receving station its step down from 440kv(primary side of the step down transformer) 33 kv.in the tranmission line,between both the primary side of the transformers the voltage is 440kv.then how the power flows in tranmission lines?
- I think you will find that the primary side of the transformer is not necessarly the input side. So the 33kv is the input voltage connected to the secondary. The 440kv is the output from the primary, and the input to the second transformer. In both cases it is connected to the primary of the transformer but one transformer is used in reverse.
- Q:Transformer 1KVA can load how much security, how to calculate the formula
- You only give a parameter, that is, KVA, you have to give two dollars to count
