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 have a 240 to 12 volt electronic transformer for each 50w halogen bulb. Trying to track down a fault, I tested the transformer with my multimeter - it showed 240v input but showed zero v output so I concluded that the transformer was faulty BUT when I plugged in a bulb it lit up normally. Can anyone explain ??
- Transformers have a generic winding and a secondary winding. they are wound with a ratio in recommendations. The ratio is the secondary divided by skill of the common. occasion: a generic winding of one hundred turns and a secondary with 10 and a hundred and twenty volts on the common : a hundred and twenty * (10/one hundred) 12. this might grant the needed output voltage needed. some transformers have distinctive faucets so which you would be able to get distinctive voltages from the a number of connections. in case you're desiring greater effective than 3.9 volts, you will be able to desire to purchase one which has the splendid voltage.
- Q:b)Describe an important industrial application of one of the above devices (apart from transformers)C)Explain how this device works-that is ,what the electricity actually does
- A transformer is a device that allows you to easily and efficiently convert an AC voltage to a different voltage. When you do this, the current is converted in the opposite ratio. For example, if you have a 100 volt 1 amp source and you convert it to a 1000 volt source, it will have capability of 0.1 amp. It is made by winding wires on iron cores. See the reference for details. It is very important for the transmission of AC power, as it can be changed to a very high voltage for efficient distance transmission, and back to low voltage for use in homes. .
- Q:I have a US Navy Plate and Filament Transformer Manufactured by Hudson American Corporation.This monster weighs 14.5lbs, and is in a sealed steel casing.There are 16 unlabeled terminals, and I'm working to identify those.It does however have the current and voltage labelings for the primary and secondaryPrimary : 110/115/120v AC (Since there are 16 taps, I'm guessing that these are separate primaries)Secondary 1:360-0-360 200MA DCSecondary 2: 6.6v 10A CTSecondary 3: 12.6V 3ASecondary 4: 5.25V 3AI'm set on using a solid state rectifier circuit so i don't need the 5.25V Line, or the 12.6V line.Could I somehow do something to get extra current on the B+ line (S1 windings) with these unused secondaries?I want 4x 6550/kt88, so the extra plate current would be great to have around.
- Get get right of entry to to an impedence meter and degree what the transformer relatively is (impedience clever). you will discover small transformers with an identical turns ratio and not additionally be near to what you like. If there's a marking on the transformer , you're waiting to seem it up. the different element is that utilising tubes at very low voltages would positioned you into very non linear tiers of operation. the entire thought of utilising a triode or a tetrode amp is for a tube sound and to get low distortion or controled distortion. beginning at 5 to ten% distortion isn't great. i assume you're speaking approximately utilising something like a 3V4 or in all possibility between the tubes designed for listening to aids. Neither replace into designed for finished constancy. Microphonics are a controversy. there are a number of integrated amplifiers that are very low distortion and could no longer require an output transformer.
- Q:I have a transformer 12v and 12v need to reduce these further to be able to grow or shrink the rotational speed electromotor.Which device or component would be used to reduce the speed of electromotor?I making a mini escalators
- A transformer has AC output, so first get DC, which needs a rectifier and capacitor. Following this is a voltage regulator using an LM317 (adjustable 3 terminal regulator). This can delivers ~1 amp. You should know what maximum current your motor draws under load. The first link is an example for 1.25V-15 V with an 18V transformer. Use a 12V transformer, and a 1000 ohm potentiometer as a variable resistor instead of 2000 ohms (R2). This will give voltages from 1.25V to 7.0V DC. Use the formula to calculate other resistors for a different voltage. Get the LM317 in a TO220 package, and you will need a heat sink, at least as big as in the picture. You can probably find a kit of parts for this in an electronics shop.
- Q:I have been telling everyone that I would never get the IPad because it doesn't do anything. A tablet is a great idea, but the IPad has way better potential. The IPad is currently useless. You could have music, movies, web on the go, books and games with an ITunes App store. Those are pretty much the highlights.The Asus Eee Pad Transformer on the other hand is a tablet that has music, movies, web only with wi-fi, books games, Android App market, and what i'm really looking for in a tablet, the ability to view and modify microsoft office documents (word, excell, power point). The advantage that the Transformer has is a detatchable keyboard, so it can be used as a type of netbook or tablet. The plus about the keyboard dock is that when your tablet needs charging and you connect it to the dock, it will recharge your tablet. Total battery life of the tablet plus dock is 16 hours(8 hrs/e).So now, is ther anything out there similar to this Eee Pad Transformer worth considering? Should I get it or not?
- asus transformer is definately better than the ipad2. so far ipad 2 is nothing more than a fancy toy to glare at other than design cant give it any props. it makes even less sense to buy if you already have an iphone cause the only difference between the two is the size of the screen.
- Q:I think the power supply to my external hard drive has failed. Is there anyway I could replace the transformer. There is no way to contact the manufacturers as they have the worst customer services ever (Formac). I have emailed them 5 days ago without a reply.
- The in the manual or on the device it should state what the voltage and current or power requirements are. It will state this in volts (in AC or DC) along with milliamps (mA) or watts (W). The wall wart should also state what it has on its output. Typically the outside is negative with the inside being positive. Make sure that any aftermarket or replacement transformer is exactly the same voltage. The amperage or wattage capacity should be the same or greater. (ie a 300 mA can be replaced by a 500 mA or 0.5 A but not a 100 mA) The obvious match of the connector should not be overlooked. If it is too big it will not fit, but if it is too loose it may cause excess current to be needed and may damage the device. An electronics store should be able to set you up with a multi-adapter, multivoltage charger / DC powersupply. Here are some examples of replacement supplies.
- Q:A 8000kva transformer can bring the maximum load
- A good transformer can work at full capacity. But affect the service life. It is best to 80% of the power of this transformer is the best.
- Q:given that volts x amps watts why dont they just rate a transformer by kilowatts. I havent been able to link the logic behind rating a transformer by KVA, but there must be a reason. If you think you can help me I am eager to learn and will appreciate your help.
- well from what my teacher told us kilowatts is reserved for real average power. As you know inductors and capacitors have no average power which means that the power in those elements are just being recycled over and over again. for sinusoidal steady state this power is imaginary (mathematically) and is giving the kVA. It's just terminology.
- Q:If it is powered by a DC source, will there be a Back EMF generated? Why/Why Not?Obviously, there will be a higher current flowing than that of a AC supplied transformer, but I don't know why.Thanks.
- A transformer uses magnetic flux changes in the primary coil for induce a voltage in the secondary coil, the relation between the voltages is given by: Vsec N2(dΨ1/dt) (Faraday's law of induction) Ψ1 k*N1*I1 Then Vsec N2(k*N1*dI1/dt) where: N1: number of turns in primary coil N2: number of turns in secondary coil Vsec: Voltage in secondary coil Ψ1: magnetic flux in primary coil I1: current in primary coil k: constant involving Reluctance and others parameters If the current in the primary coil is DC (a constant) then his derivative must be zero, then Vsec 0
- Q:does anyone know what the songs are in transformers???????
