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:Why is the transformer coil insulation?
Because the transformer is used in different environments, according to different insulation level selection, can extend the life of the 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.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:transformers movie?
Well, I thought the movie was great. And yes, I think she was very pretty. I didn't see that her acting was as awful as everyone is saying. I think people were expecting it to be an Oscar winner, when really all you could expect was to have a good time watching the special effects and the robots beat the crap out of each other. Like, the first scene where Bubblebee and the cop-car battled that was thrilling people overlook that. I think, at least. Anyway, you already know my answer from a previous question about the movie. I thought it was great. I even saw it twice, and I see NO movie twice.
Q:When hot wiring two 12 volt transformers does the voltage become 24 or 12 volts?
There is actually a phasing to the transformer windings. If you connect them in series with the phases adding (both hit + 12 at the same instant) you get 24 volts out. If you connect with the phasing wrong (one hits +12 while the other hits -12) and put them in series the output will be zero volts (and they might overheat). If you connect them in parallel with the right phasing you will get 12 volts and the amperage will add to give you the sum of their amperage. If you connect in parallel with the phasing wrong you will get zero output voltage (and the danger of overheating). If the transformers do not make their phasing clear put a voltmeter on the output and briefly turn on the primary while seeing if you get zero or the voltage you want. If the phasing is wring swap the wires of one transformer around and check with the meter again.
Q:Replaced halogen by LED, how to prevent transformer shutdown?
Low Voltage transformers (ELV or MLV) are tricky. Just because you have the voltages the same doesn't mean you have the right current being drawn by the LED's.It could be too low or too high. Were the original halogens MR16 form factor as well? I'm guessing the xfmr was specifically designed for a set voltage/current/power. Consider this: Two 20W halogens 40W. PowerVoltage*Current 2012*I I 1.67 amps through each bulb, 3.33 amps total drawn from the xfmr Transformers operate on the principle of Power in Power Out. The xfmr is probably designed to provide 40W, regardless of whatever current draw you put on the transformer. The LED's only need 6W from the xfmr. However, the xfmr probably doesn't care. It's still spitting out 40W at 3.33A. 0.5A (2*3W/12V) is all the LED's need. If the xfmr is still trying to provide 40W at 0.5 amps, the output voltage is compensated up to 80V coming from the xfmr. Most LED bulbs have protection for this in the engine, (the regulator/stabilizer as you call it), called over-voltage protection. This is probably whats causing the bulbs/transformer to fail. The problem is, especially with transformers, is that you must match the load. If the transformer is expecting a specific load and you give it something it can't handle, it'll either destroy the load or damage the transformer. The easiest way to avoid this is to always match the power of the original load to the load you intend to put in. 40W of halogens should be matched with 40W of LED. This is the gimmick with retrofit bulbs like the MR-16. You're not really saving any energy when you use retrofit bulbs. You just get a longer bulb life and a lot more light from the same power draw. LED lighting is a niche market. If you can't figure it out, wait a few months and LED lighting fixtures will decrease as the market is flooded with new product and becomes more competitive. I'd recommend investing in something like that instead of retrofitting.
Q:Does a transformer act as an inductor at the same time while in use?
Yes - a transformer is an inductor with a second winding that is coupled to the first via the magnetic field they share. But using the transformer as an inductor will reflect whatever load is on the secondary winding into the primary to diminish the Q and possibly alter the inductance of the primary, and this will affect the bandpass and slope of your filter. Best to get the filter section working right and follow that with a buffer amplifier to isolate it from downstream loading.
Q:How to open a transformer?
Never attempt to prise apart sealed units.There is a risk of explosion.
Q:Transformer 1KVA can load how much security, how to calculate the formula
This is based on the voltage count, such as three-phase 380V. 1KVA current is basically 1.5A
Q:Electric transformer?
dont worry .you cannot get a shock from 12 volt dc low wayyage transformer.as long as you touch the output wires .DONT FOOL WITH THE IMPUT WIRES you cant do much damage whatever you do with the output
Q:Transformer voltage ratio and current ratio.
In theory, the transformer voltage ratio is equal to the turns ratio, the current ratio is equal to the number of turns inversely proportional. There is actually a slight difference.
Q:Your opinion on Transformers: Dark of the Moon (video game)?
Transformers: Dark of the Moon is still an enjoyable game, but I don't think it's worth $60. I usually buy games at $20 and even then I was very glad that I just spend $2.15 to have rented this and even able to finish it and played some multiplayer in 2 days.
