Product Description:

1.Product description
SC(B)10 resin-insulated dry-type transformer is designed basing on the Dupont(the USA) NOMEX paper insulation system. the other key components are made from imported materials (such as german MKM copper foil). with advanced manufacturing equipment and technology, the product enjoys high performance, low energy loss, safety and reliability, its especially suitable for high buildings, airports, substations and commercial centers, and any other anti-fire, anti-explode, anti-moisture places etc.

Q:is a dc transformer practically possible?
What you need is a DC to DC converter, not a transformer. Vicor make the best ones. They will accept a range of input voltges, some of them will accept quite a wide range.
Q:submerging transformers in oil?
Only impurities will have an effect on insulation. Best if boiled first to remove any condensation, then seal the container.
Q:10 (6) What is the meaning of 10 and 6 in the KV transformer?
Are the high voltage side of the input voltage were 10KV and 6KV units of kilovolt
Q:Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
1, no excitation adjustment or no taps. 2, with taps. Their advantages and disadvantages are as follows: 1, no taps: taps when the transformer must be shut down after the power, the advantages of safe and reliable, but the disadvantage is to adjust inconvenient, and often because the tap position can not meet the needs of less. 2, with taps Advantages: easy to adjust, do not have to turn off the transformer power can be adjusted, and the general tap position more easily meet the requirements. Disadvantages: due to load adjustment prone to problems, high cost, compared with the same capacity transformer volume, taps device maintenance needs a long time to blackout.
Q:What is the other species of transformers?
i think ur talkin abt unicron, When Primus first created Cybertron, he created a crew of thirteen living robotic beings to man him. These beings, in imitation of Unicron's transformation abilities, were able to change their forms into the likeness of vehicles, weapons, and machinery. They were the first Transformers, and seven were Primes. Many of the thirteen died in a cataclysmic first battle with Unicron, where he was sucked down into a black hole and trapped along with his acolyte known as The Fallen, one of the thirteen who had turned against his brothers and joined Unicron. Of those that survived, many abandoned their original functions and were lost to time. Only Vector Prime was known to still be following the path he was set upon by Primus. The ThirteenEdit Prima, the first Matrix-bearer and first Transformer born from Cybertron, leader of the 13. The Fallen (originally Megatronus Prime), the guardian of entropy Alpha Trion who can see the past, present, and future, and who holds the Covenant of Primus and the Quill Vector Prime, the guardian of space and time Nexus Prime, the guardian of the multiverse's Rarified Energon, capable of splitting into 5 smaller robots: Skyfall Landquake Breakaway Topspin Heatwave The Liege Maximo, the ultimate evil counterforce of good An unnamed female warrior Logos Prime (possibly) The Last Autobot (possibly) Maccadam (possibly)
Q:Is there a step up transformer that can produce 10 volts froms a 1/2 volt variation in the primary winding?
This is a voltage step up transformer. What is needed is winding turns ratio of 1 to 20. This means that for every turn of wire in the primary, the corresponding number of turn in the secondary is 20 thus if a voltage of one volt is applied in the primary, the output will be 20 volts. It should follow that if the input is 1/2 volt, the ouitput will be 10 volt.
Q:A question about Transformers URGENT?
A transformer simply changes one voltage to different voltage. There is some voltage change due to I*R in the transformer, but the transformer doesn't regulate the voltage.
Q:Microwave transformer wires?
The bottom coil with the 2 tabs is the primary. The 2 red wires leading off to the right is a low voltage secondary with high voltage insulation so that they remain isolated from the other windings. It powers the filament of the microwave tube. The other red wire leading off to the left is one end of the high voltage secondary. It normally connects to a high voltage rectifier and capacitor and then to the cathode of the tube via one of the filament connections. You can expect to see negative pulses in the 2000-3000 volt range at that connection with an available current that is several times the lethal level. The other end of the high voltage secondary is grounded to the frame of the transformer at the rivet at the top center. The anode (plate) of the tube is also grounded through its mounting hardware. Most microwave transformers run hot even when lightly loaded since they are run fairly close to saturation on the B-H magnetization curve. You'll need a fan if you are using it for extended periods. If you carefully remove both secondaries and the steel magnetic shunts wedged in between the primary and secondary windings, you'll have the foundation for winding your own transformer good for about 400-600 watts. First add about 10 more turns to the primary which will cut the core losses significantly by running it lower on the curve. Expect to see about 1 volt per turn on any new secondaries you wind. Don
Q:Transformers and its operations?
Assuming perfect transformer. turns ratio 1600/80 20:1 secondary voltage is 220/20 11 volts primary current is 44/220 0.2 amps secondary current is 0.2 x 20 4 amps drop across wires is 4 x 2.5 10 volts. This assumes the 2.5 ohm number is for both leads, not each. voltage across lamp is 11v – 10v 1 volt power in lamp is 1 v x 4 a 4 watts. .
Q:Physics: Transformers Help?
The ratio of voltages in the windings of a transformer is the same as the ratio of turns of wire in the windings, so in this case the voltage ratio is 1 to 10. If you connect the primary to a source of 120 volts, the voltage induced in the secondary winding is 10 times as much, or 1200. If a (pure) resistance of 1000 ohms is connected to the secondary winding, the current (I) that flows is found by Ohm's Law: I E/R. Since E is 1200 volts and R is 1000 ohms, I 1200 / 1000, or 1.2 amperes. The power P in the secondary coil is found by multiplying the voltage by the current, so P 1200 times 1.2, or 1440 watts. Transformers are very efficient, and the power in the primary coil is essentially the same as that in the secondary, or 1440 watts. The current drawn by the primary coil is found by dividing the power by the voltage: 1440 divided by 120 12 amperes. Hope this answers all parts of your question.
