Q: i went to see transformers on july 3rd. they had about 5 or 6 previews before the actual movie started. the very last preview showed and party to someone called bob. he was leaving, going to japan. then the lights went out and a big groan was let out and a earthquake happened. they all went out to the roof, and in the distance, a big orange ball was exploding, shooting out fireballs and lava. they only said it was coming out on january 18 2008, and they didn't give the name.please help, i need the name of this movie: It's okorder

Q: I am a transformer factory salesman, the company let go to the field to run business, if you go to a strange city, where the main starting from where the few places, and which units to contact? If the local sales in the transformer factory, then work well to carry out? What are the sales channels?: 1. Power supply company tender 2. Cabinet manufacturers 3, the installation company 4, direct customers, to the planning bureau to find, in advance to know which new project 5, design institute, know some late 6. Power supply company front desk, people come to install more late

Q: Three-phase three-winding transformer high-pressure medium-pressure low pressure is what it means: Hello! Transformer high voltage, medium pressure, low voltage, respectively, refers to the three groups of winding (rated) voltage level. For example: 220kV voltage level of the transformer: the 220kV high voltage side, 110kV pressure side, 10kV low voltage side of the three groups of voltage levels of the composition. Depending on the needs of the manufacturer, manufacturers may also be required to produce windings for other voltage classes. Such as: by the 220kV high voltage side, 35kV in the pressure side, 10kV low voltage side of the three groups of voltage levels of the composition. 500kV voltage level of the transformer: generally by the 500kV high voltage side, 220kV medium voltage side, 35kV low voltage side of the three groups of the composition of the voltage level winding.

Q: I wa watching the films and was wondering how the transformers just spawn more and more. For example soundwave made the panther thing then it made the thin robot and all those construction guys too, then they made the huge robot with the balls.: It's all science fiction.

Q: I thought the movie was great, but the death of Megatron seems really rushed and just unsatisfying? Agree?: I like the new Transformers but if he and the future bad guys lives, then they will stretch out the series and from story to characters, things will get crappy and I don't think anyone would want that.

Q: 630kva dry-type transformer rated current is how much: If it is a 10kV transformer, Then the rated current = 630 / 10.5 / √3 = 34.64A, which refers to a current, phase current

Q: I have a few questions about flyback transformers: How high of a frequency can they go without alot of losses?Can I get a negative High voltage by reversing the polarity of the primary?How can I make the flyback safe from the capacitive charge that it holds?: The flyback transformers used in TV's work at about 15000 hertz (the horizontal scan frequency). The transformers used in switching power supplies are smaller and work at a higher frequency, but they normally have a low voltage output. The transformer produces a high AC voltage, and a rectifier diode changes it to DC. Reversing the diode gives you a negative output. The picture tube provides capacitance to smooth out the voltage and holds the voltage for a while after the power is turned off. If you don't use a picture tube, you might need a capacitor if you want a steady output voltage. Shorting out the capacitor will remove the voltage.

Q: i just got back from seeing transformers and the special effects were awesome but the storyline could have been better. I thought the girl meghan fox was so prettywho thought the same?: Well, you can call me nuts! It was so goood, I watched it FOUR times. So good, I'm thinking of going for a 5th! (4 is bad luck!). To me, Transformers just broke the barrier when it comes to making robots that interact well with humans. The awesomely human-like behaviour of the Autobots, the cool action scenes, fast but cool transformations and the god-like Optimus Prime took my breathe away! Absolutely the best movie this year. No one could ask for a better live adaptation of a cartoon, especially one that we used to love.

Q: Transformer stop power operation, the neutral point must be grounded: A measure taken to prevent overvoltage damage from being turned off the transformer. For the high voltage side of the power supply of the power transformer, when the circuit breaker is not full phase pull, if the neutral point is not grounded the following hazards: 1 transformer power side of the neutral point to ground voltage up to phase voltage, which may be damaged Transformer Insulation 2 Transformer between the high and low voltage winding capacitor, this capacitor will cause the high voltage to the low voltage "overvoltage" 3 When the transformer between the high and low voltage winding capacitive coupling, the low side voltage will reach the resonance conditions, may There is resonance over voltage, damage insulation.

Q: explain the role of both types of transformers in getting electric energy from an electric power plant (coal-fired, natural gas or nuclear) to our homes.: A step UP transformer is used to boost the VOLTAGE, as by doing so the CURRENT is reduced by the same factor, e.g. boost voltage by 100 x, reduces current to 1/100th. By reducing current, power losses due to the transmission line RESISTANCE is very significantly reduced, especially in long run distances between consumers and the generating plant. The formula I^2*R is power, and the square of (say) 100A is 10,000, whereas if the current were reduced by 100 fold as above, the current becomes 1A., so you can see the difference! 1^2 1, versus 100^2 10,000. But the voltage is too high for consumer use, So a step DOWN transformer is used to change the voltage down to the required domestic voltage. The ratio of this transformer can easily be adjusted to allow for the minute power lost in the high voltage lines. The overall effect is very much less power lost in heating the connecting wires in the transmission lines, so much more power available to consumers.
