Q:Where can I buy transformers?
Transformers as in the action figures? You can find them at Toys R Us, Wal*Mart, or Target.
Q:Question about transformers?
The previous answer is correct, but the following may be helpful. A transformer works by the linking of changing magnetic flux produced by one loop or coil (the primary winding) with another coil (the secondary). That is why transformers only work with alternating current or pulses. Magnetic iron has the ability to increase the magnetic flux produced by a coil. This is called its magnetic permeability and can increase the flux produced by factors of several thousand or more. Leakage flux in a real transformer is the amount of flux produced by the primary that does not link the secondary. This flux is wasted and reduces the efficiency of the transformer. Heating of the wire insulaltion not only comes from the resistive heat of the windings, but also the heat produced in the magnetic material (core) of the transformer. These losses are called eddy current and hysteresis losses and can be quite substantial. The reason that cores of transformers are laminated (stacked thin sheets of magnetic iron) is to reduce the eddy current losses.
Q:New on the transformer reported to stop, how to do,
Second, if it is a large industrial electricity price, in order to save the basic electricity costs, is the power supply enterprises can apply for disabling procedures, but the new transformer need to comply with the "power supply business rules" provisions, reported there are two procedures, Capacity, the second is suspended: Article 23 of the Power Supply Business Rules The user will be required to apply to the power supply company five days ago. The power supply enterprise shall handle the following provisions: 1. The reduction must be the whole or the whole group of the transformer to stop or replace the small capacity transformer power. The power supply company shall, upon the date of acceptance, seal the equipment according to the date on which the user applies for the reduction. From the date of the seal, according to the original billing method to reduce the corresponding capacity of the basic electricity. But the user stated that the permanent reduction or from the date of the expiry of the expiry of two years without the resumption of electricity procedures, and its capacity after the reduction has been less than the implementation of the two-tier price of capacity standards should be changed to Single system billing;
Q:500KW load should be installed how much transformer?
According to the power factor of 0.9 and 20% of the margin, you need to be equipped with 500 / 0.9 / 0.8 = 694.4, you can take 750 kVA capacity can be. If it is with the motor and other load-based, due to power factor and start-up current reasons, at least 900 kVA more appropriate. If the drive of the motor more than 200 kilowatts, start a large current, you need to put a larger margin or the motor using step-down start mode.
Q:Why does the transformer have three lines
There are three lines is normal, because in addition to a line of fire a zero line, there is a ground wire (ground wire is directly connected to the Earth's line, it can be called a safe circuit, dangerous when it put high pressure directly To the earth, be a lifeline. 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 use can be divided into: power transformers and special transformers.
Q:220 kv transformer capacity range,
GB GB / T6451 made a detailed provision, the latest version of the 2008 revision. (Boost, buck), three laps without load (boost, buck), autotransformed (boost, buck), the two-lane, There are several types of auto-load (boost, buck) and so on, there are about 31.5,40,50,63,90,120,150,180,240,370,400 MVA several grades, but corresponding to different types of transformers, Capacity level is slightly different, do not know what type of capacity you ask the range?
Q:What is the End of TRANSFORMERS SERIES??
In the Transformers movie from the 80's, Optimus Prime is killed by Megatron. He gives the mantle of leadership to his 2nd in command (another large tractor trailer truck named Ultra Magnus) During his death though the mantle is handed to Hot Rod for a moment and the audience sees that he is the true leader it was meant for. At the end of the film he received the Mantle and becomes Rodimus Prime. Megatron however in fighting Optimus was gravely injured along with several other Decepticons. On the return flight to Cybertron, it is decided that they need to rid the ship of any unnecessary weight so as to make it possible to return (all the way) to Cybertron. Megatron is one of the last thrown over board and StarSCream becomes the new leader. As Megatron floats through space, he comes across the path of Unicron who is the largest transformer (Moon/planet size). He gives Megatron life again in the form of Galvetron. Only catch is he must serve Unicron. His first order of business of course is to kill Starscream (takes about 10 seconds). Convoy is Optimus Prime's name in Japan's version of the show. Additionally, in the series you are currently watching, Optimus is brought back to life twice and remains with them as leader through the end of the series. The series has had many lives so there is no definitive end to the characters yet. I could give you a ton of other info, but I think this is what you needed.
Q:can i make a transformer with the help of chemical?name the chemical pls or any books websites for it?pls help?
to transform WHAT into WHAT?
Q:Your opinion on Transformers: Dark of the Moon (video game)?
I didn't like it.
Q:short-circuit and open circuit transformer question?
read material regarding transformers Not just once but say 5 times, till you understand what is said. the transformer has copper loss due resistance of primary and secondary. It has additionally iron loss. The equivalent circuit is a sort of representation that brings in these losses. generally you can apply a low voltage to primary till shorted secondary has a current equal to less than rated current. These measurement details are given. Similarly open circuit measurement details are available. With understanding of how the rest can be calculated using worked examples in texts, you can solve it yourself. attempt this See Lee's book on transformers or schaums series on electrical engg.
