Performance characteristics
1.A multilayer cylinder structure is used for all high voltage windings in order to improve the voltage impulse distribution of windings.
2.For the capacity range of low voltage windings is from 30kVA to 2000kVA,the cylinder type or spiral structure is used to ensure the high mechanical strength,ampere lure distribution,and excellent short-circuits proof performance.
3.The securing structure is set in the transformer body,which is used for ensuring that no displacement will occur during the transportation;meanwhile,the turnbuckles are mounted in fasteners,which is for assuring that fasteners will not be loose during the long term operation.
4.Corrugated tanks are used in transformer for replacing the conservator.The tank enclosure and rim are completety sealed by welding or bolting up,which prolongs the service life of transformer oil.
5.The transformer surface are painted with primer and finish coats after derusting,and phosphorizing;which can meet the special operation requirements in metallurgic and petrochemical industries,as well as,in moist and dirty places.
6.The press relief valves,signal thermometers,and gas relays are equipped in the oil tank of hermetically sealed transformer in order to the standard requirements for safe operation.The transformers are attractive and competitive due to the compact shape,excellent design,and maintenance-free.

- Q:How to test the transformer capacity
- If the temperature rise of a transformer is less than 55 degrees, it can be considered to achieve the design capacity. ? As the temperature rise test time is long, the customer can not track the whole process, some bad transformer manufacturers in which mischief, cut corners, made the transformer can not reach the design capacity.
- 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.
- transformer is only chenge value of ac and dc does not flow through transformer. and transformer work on the principle of electomagntic induction only induced current from primary coil to secondray
- Q:What are the ways of protecting the transformer?
- Large transformer main protection is differential and gas, backup protection including temperature, quick overcurrent and so on!
- Q:I have a bulb that currently uses a 120V primary to 6V secondary transformer. The load is a 30Watts. I would like to know what transformer I could use to power 8 bulbs (6v 30W each) ? Thanks. How can I calculate that?
- Assuming you wire the bulbs in parallel. You need a similar transformer (6v secondary) but one that is rated at 240 watts (or a bit more), 40 amps. Note that the current will be 40 amps and will need quite a heavy wire, #4 or 5. You could also put the bulbs in series, and would need a 48 volt secondary, still at 240 watts. You would have problems of any series string, if one bulb goes out, they all go out. You can also use parallel series combos, 3 pairs, or 2 strings of 3 each as a compromise. edit. Later thought of another alternative that may help. Get a transformer with a 12vCT 240W secondary. Wire like you would 2 phase house wiring, 3 bulbs to each outside terminal, and all 6 to the CT. This means the wire only has to handle 20 amps and can be smaller, and you will not have the series string problem. 12VCT transformers are fairly common. Or if you can find it, and the wiring is still a problem, get a transformer with 2 secondaries each of 12VCT at 10 amps.
- 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
- During the main transformer failure or overhaul, the auxiliary transformer provides the substation's own electricity. Maintenance of substation lighting, high and low voltage switch action, with the cabinet switch operation, for instrumentation and automatic control system work, sub-change can be box change,
- Q:An AC adapter for a telephone answering machine uses a transformer to reduce the line voltage of 120 V to a voltage of 8.00 V. The RMS current delivered to the answering machine is 570 mA. If the primary (input) coil of the transformer has 600 turns, then how many turns are there on the secondary (output) coil?What is the power drawn from the electric outlet, if the transformer is assumed to be ideal?What is the power drawn by the transformer, if 13.5 percent of the input power is dissipated as heat in the coils and in the iron core of the transformer?
- Hello Samantha, in case of ideal transformer the power at the out put would be the same as that in the input. To get the power we need voltage and current. Voltage at the out put is 8 V and current is 570 mA. Hence power consumed by the machine is 4.560 W. So the power drawn in case of ideal transformer will be the same as 4.560 W If the efficiency of the transformer is 86.5% (100-13.5) then the input power will be 5.27 W (approx) To get the number of turns in the secondary let us use Ns/Np Vs/Vp Hence Ns 600*8/120 40 turns.
- Q:Transformer is the transmission of electrical equipment
- The transformer is an electrical device that converts the AC voltage level to achieve the purpose of power transmission.
- Q:I have a small question concerning flyback transformers. I have run into some confusing problems when i tried testing the flyback using the High voltage power supply project
- The frequency of an ac power supply is only 60 hz. That's way too low for a flyback. The resistance of a transformer depends on the frequency. At 60Hz a flyback transformer acts like a short circuit. It would draw a lot of power, might damage the power supply and nearly nothing would come out the other side of the transformer.
- Q:I have been told by multiple people variable transformers reduce amps and volts simultaneously, Since transformers reduce amps to increase volts, how is this possible?also, if i want to reduce amps while maintaining volts for a source of 10 amps at 120 volts could i connect a variable transformer and reduce the source to 60 volts and 5 amps, then run that output to a step up transformer at 120 volts and 2.5 amps and then connect this to a 1200 watt electromagnet, will it only draw the 300 watts provided at 120 volts and 2.5 amps? or will it draw as much current as it can?
- You were totally lost or you were misguided by someone whom gave you the wrong information on variable transformer compare to a standard transformer. A variable transformer ( we called it auto-transformer ) can raise voltage say from 1V till 145V for a standard 120V power source application. Its output current is limit by its VA rate due to its wire size and core size. Suppose it rated 500VA, then its maximum current limit is 4A. In another word, this transformer can support 4A maximum current from 1V till 145V at any voltage setting. If over 4A load at any voltage between 1V to 145V could burn the coil because it uses one size wire for one coil. Reduce voltage with a transformer does not reduce ampere from transformer. It is the load determine the amperage. You were so confuse again ! Here is an example. 100W lamp draws 0.83A at 120V By reduce the power source into 60V , 100w lamp draw 0.417A It is not the transformer limit its output current into 0.417A. It is the lamp resistance causing current comes down while voltage comes down. From Ohm's law. current E / R As E reduces into half, current passing lamp reduces into half. DO YOU UNDERSTAND NOW ! One more thing to remember.energy cannot be obtained from nowhere, transformer is a voltage exchange device which has no gain. You do not expect obtain extra energy by using transformer.
- Q:And what are the prospects for Transformers 3? I mean, should i just skip it?I forced myself to watch Transformers Twice. Didnt care for it much, either time. Barely, BARELY passable.
