4. Reference Picture:
- Q: I am curious. These were popular '80s kids' cartoons. Referencing these cartoons in shows like Family Guy and Robot Chicken doesn't mean they are still popular. Are they still popular? In '03 they tried revamping He-Man in a new series but that didn't last long. They still show the classic Transformers and G. I. Joe cartoons on the Hub. They had some new toons based on G.I. Joe and Transformers and a few movies.
- Yes. Transformers and G.I Joe is Still running through the Veins of this Generation, But He-Man is Kind of Not So Popular They Don't even Show He-man TV Show in channels, He-Mans drop was his costume that Gave him a Gay look. Transformers and G.I.Joe is still being watched, So there are more than 4k Fans
- Q: What are the technical parameters of the transformer?
- I, temperature rise and cooling: transformer winding or the upper oil temperature and the temperature difference between the ambient temperature of the transformer, known as the winding or the upper oil temperature rise. Oil-immersed transformer winding temperature rise limit of 65K, oil surface temperature rise 55K. There are a variety of cooling methods: oil from the cold, forced air-cooled, water-cooled, tube, chip and so on. J, Insulation level: Insulation class standard. Insulation level of the method for the following example: high voltage rated voltage of 35kV level, low voltage rated voltage of 10kV level transformer insulation level expressed as LI200AC85 / LI75AC35, which LI200 said the transformer high voltage lightning impulse withstand voltage of 200kV, power frequency withstand voltage For the 85kV, low voltage lightning impulse withstand voltage of 75kV, power frequency withstand voltage of 35kV. Oaks High Technology Co., Ltd. The current oil-immersed transformer product insulation level LI75AC35, said the transformer high voltage lightning impulse withstand voltage of 75kV, power frequency Withstand voltage of 35kV, because the low pressure is 400V, can not be considered. K, the connection group label: According to the transformer one. Secondary winding phase relationship, the transformer winding connected into a variety of different combinations, known as the winding group. In order to distinguish between different groups, often using the clock representation, that is, the high voltage side of the voltage phase of the clock as a long needle, fixed on 12, low voltage side of the phase voltage as the clock short needle, (A) is a (triangular) joint, and the secondary winding is a (star) junction with a center point, and the group number is (11).
- Q: I know that if I needed 600 watts at 120 volts that I would need at least 5 amps, but does the step down create a difference in amperage when using a transformer converting the 120v. to 12v?
- 600 watts at 120 volts is, as you have calculated, equals 5 amperes. Yes, if the transformer were 100% efficient, the secondary would be able to supply 600 watts at 12 volts, or 50 amps. Let's assume it's 70% efficient; that would still allow it to deliver 35 amps.
- Q: Do stores that sells computers, printers, etc. also sell transformers
- Transformers as in the action figures? You can find them at Toys R Us, Wal*Mart, or Target.
- Q: anyone have any pictures ideas on how to do a transformers cake???? i need one for this sunday any help would be appreciated
- Transformers (cake) more than meets the eye! Go to the movie website. I think you will have better luck having a bakery do this for you.
- Q: If you have two 12 volt transformers and if we connect their hot wires together 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: Rated capacity of three-phase transformer S = √3 * U * I
- S is the total capacity of the three phases, is the apparent power, the unit is KVA. The sum of the three phases is equal to the sum of the three single-phase capacities, ie S = 3UI where U is the phase voltage and I is the phase current. If the line voltage line current, then S = √3UI This is because when the winding is triangular connected, the line voltage is equal to the phase voltage, the phase current is equal to 1 / √3 times the line current, 3 / √3 = Similarly, when the star is connected, the phase current is equal to the line current, the phase voltage is equal to 1 / √3 times the line voltage, the same 3 / √3 =
- Q: about transformers
- Your logic is valid but a careful look will tell what is happening. This strange behaviour is not that uncommon, it has analogy in other areas also. For example when you push a large stone, it is pushing you back (famous third law), then how does it move at all, if it cancels the supply force? On the other hand when you push a strong wall, it reacts with equal and opposite reaction. The thing is if the wall did not exert this reaction it would have allowed itself to be pushed back without any resistance!! These action / reaction like, supply voltage and induced emf (other examples are terminal volt of a d c motor and back emf, generator output and its reaction on prime mover etc etc) are all must be conceptually understood. I can dare say that they do not exist as such! They are merely way of understanding the concepts. When you supply ac volt to a coil (transformer without secondary load is just a coil) because of energy transformations taking place we see that the coil offers resistance much different from pure resistance, which is called impedance. But the same can be viewed as reduction of available voltage due to induced emf. I repeat this is a conceptual understanding of the phenomenon.
- Q: If a power surge from a house shot back towards a transformer, would it ground the charge or bypass the transformer and harm the surrounding wires?
- No, the transformer itself wouldn't ground it. I don't know if they have some kind of surge protector, by the transformer would just 'pass it on' (most likely blow a fuse if the trannie survived
- Q: a house's two furnaces are not working. the pilot lights are on. The lady's brother said there is no voltage at the thermostat. where does the 24 v come from? a transformer ? where?
- should be on the furnace. however the pilot light doesn't need the voltage to light. the solenoid does need the voltage to open.
