2. General

The three-phase oil-immersed distributing transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.

As high-tech product that promoted by the country, the product has many advantages such as high efficiency, low loss. Its social benefits are remarkable that it will save much of electricity consumption and operating cost.

Q:How do I select a transformer connection group?
Both transformers are center-point direct-to-ground transformers. Dyn11 wiring group of the transformer because of its high-voltage winding is triangular wiring, so when the user produces three and three times the harmonic, can be formed in the triangular winding circulation, resulting in magnetic flux to eliminate this harmonic pollution for the grid. The Yyn0 transformer because there is no triangular winding, without this function. If only an independent power supply of small capacity transformer, you can use Yyn0 transformer, such a transformer everywhere, good production. If there is a transformer that may be supplied in parallel with other transformers, or as a backup power source for other power supplies, the same wiring group as other transformers should be selected. If it is recommended for large-capacity industrial transformers Dyn11 transformers are recommended to reduce the contamination of the grid by three or three times the number of harmonics.
Q:Will the iPad 3 surpass the Transformer Prime?
I think you mean the iPad 2 HD. The rumour is that it will just be a refresh first, then iPad 3 at the end of next year. But who knows iPhone 5 got released, right? ;)
Q:Transformers : theatrical music?
i detect that lots of the time I do savor the songs/albums I finally end up loving maximum on the commencing up pay attention, just to no longer the full quantity. those that should advance on me thoroughly are not as undemanding. The songs i'm maximum accustomed to are classic rock radio standards i've got been listening to because of the fact in the past i can submit to in suggestions. i've got listened to them maximum of cases without getting unwell of them. whether i'm previous the degree of being obsessed on those songs, I nevertheless discover those songs the main common to savor. Being very accustomed to a music makes it like a convenience nutrition and quite enables my appreciation of it. even although, i would not say I inevitably choose that familiarity to get exhilaration from some thing. Familiarity purely has a tendency to weed out the catchy songs that lack actual substance. i've got no longer at as quickly as theory approximately this in the past, so I make an apology for that jumble.

Q:Which is the best 220v to 110v transformer for a guitar amp?
Transformers are pretty much a commodity item. If your 220 supply is stable, just about any transformer will do. Get one in a case with a power switch and a fuse, which is really all the protection you need. If your electrical supply is erratic you'll have to think more carefully. A 100-watt transformer is more than enough for a 30-watt amp. You could probably get away with a 50-watt transformer, but the higher rating will ensure that it runs cool and lasts a long time.
Q:rheostat on DC transformer?
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:What is an electrical transformer, and how does it work?
I know this isn't what you asked for, but it gives a much better answer than I'm willing to type.
Q:Homework on transformers?
The turns ratio is 4:1 of the primary. The power supplied to the primary is 400W. So regardless of anything else, in a ideal transformer, 400W is available on the secondary. But voltage will be 4x higher, current 4x smaller, than the voltage and current in the primary. Disregarding all that, if there is 400W of power flowing in the primary, then 400W will be being dissipated in the 20 ohm resistor. Watts in watts out, but secondary load (resistance) controls the wattage. There is no way to tell the output voltage and current, without knowing the input voltage and current. But whatever they are, the product of voltage x current will be 400W, in this instance.

Q:Transformer turns around the number and how much V is calculated
3, seeking wire diameter What is the current required to output 8 volts? Here I assume 2 am. Transformer output capacity = 8 ╳ 2 = 16 volt Transformer input capacity = transformer output capacity / 0.8 = 20 VA Primary coil current I1 = 20/220 = 0.09A Wire diameter d = 0.8√I Primary coil wire diameter d1 = 0.8√I1 = 0.8√0.09 = 0.24 mm Secondary coil wire diameter d2 = 0.8√I2 = 0.8√2 = 1.13 mm The voltage after the bridge rectifier capacitor is 1.4 times the secondary voltage of the original transformer. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.).
