2. General

SG10 type-this series dry-type distributing transformer has strong withstanding of thermal shock, overload capability. Beside, it has many good points such as flame-retardant, low-loss, and low partial discharge capacity, low noise, no harmful gas and no pollution. It is insensitive of humidity and dust, compacted, no crack and so it is easy to be maintained. Therefore, it is suitable for the using in the adverse circumstances of high requirement for fire protection, high degree of load fluctuation and dirty, moist, such as airport , power plant, metallurgy, hospital, skyscraper, shopping center, and residential areas and other special environments like oil, chemical industry, nuclear plant, nuke, etc.

Q: even in a dc transformer, the cause varying current though not in polarity, can cause a change in the magnetic flux linked with a coil.: Transformers okorder

Q: I want you guys to tell me if the movie transformers its a good movie or not? Why?Thanks, See Ya!: I think it is the BEST film i ever watched i have watched it 3 times in the cineam (sad i no) twice up romford and once in america!!!! I think it is so good because i wernt expecting muchu out of it as i thoguht it was gonna be a bit childish btu its really not juts an all round brilliant film - it never stops havin action init just non stop blood pumping film hope this helped :D

Q: How many times does a copper wire have to go around the input side of a transformer to get the necessary amount of magnetism from 110 volts?How thick does the wire around the transformer have to be if the input it 110 volts? Can it be one wire as thin as a garbage bag tie, or does it need to be as thick as the original wire, but stripped and coiled around the transformer core?: The number of turns required is NErms/(1.414 pi f B Ac) where Erms is the primary RMS voltage, f is the frequency, B is the peak flux density which is a function of the material, and Ac is the cross sectional area of the core. The current density in the wire and the physical size of the transformer determine the temperature rise due to I^2 R (and core losses). It should be less than 400 amps/cm^2.

Q: hey Guys. I'm a big fan of Transformer movies. can't wait to see the Transformers-2. Not a real trailer has been released? :( . I would like to know which robots r going to b in the next epic battle?? :): Soundwave. Optimus Prime 3

Q: How can you tell. Is it because (3) wires come off of a single phase transformer? And (4) off of a three phase transformer? Thanks!: That would be a clue. If the transformers are mounted on power poles they will be exposed. For three phase you would see three separate transformers wired together.

Q: A transformer consists of 250 primary windings and 838 secondary windings. If the potential difference across the primary coil is 25.5V , what is the voltage across the secondary coil ? If the potential difference across the primary coil is 25.5V , what is the effective load resistance of the secondary coil if it is connected across a 135Ω resistor?: Transformer equation, N_pV_pN_sV_s V_s (N_p V_p)/N_s, plug in the numbers and calculate. N_p/N_s sqrt(Z_p/Zs)

Q: Hope to engage in the transformer predecessors to answer. I hope you help me introduce a little more recommended information better: Oil-immersed power transformer is one of the company's leading products, the original Ministry of Machinery Industry planning in Shandong Province, 220kV and below the production of the only key power transformers. Product voltage level 6 ~ 220kV, capacity 30 ~ 360000kVA, including 23 series, more than 200 varieties, more than 1,400 kinds of specifications, the technical performance indicators all meet the national standards and the International Electrotechnical Commission standards. The company has designed and manufactured the first domestic 110-kilovolt 31500 kVA three-coil aluminum transformer. Since the 1982 production of 220kV transformer, the product has been used in sunshine, Taizhou, Jiangxi and many other national key projects

Q: i am recently watching transformers prime and i am a big fan of all transformers but now i am confused.i generation 1 and 2 was good then they ended.does transformers cybortron trilogy a sequel to g2 or new start and then is tranformers prime a sequel to transformers fall of cybortrons?: 1) In the G1 timeline we have a sequel series made exclusively for Japanese audiences. They completely ignore the events in the American ending and go in a completely different direction. 1) Transformers: Headmasters 2) Transformers: Super-God Masterforce 3) Transformers: Victory 4) Transformers: Zone Then there's Beast Wars and Beast Machines is a sequel/prequel to the G1 series. ___________________________ 2) Transformers: Robots in Disguise (RiD) aka Transfomers: Car Robots in Japan is a complete standalone series, no relation to any other existing TF series ____________________________ 3) The Unicron Trilogy is it's own timeline that has 3 series. US - JP Armada - Micron Legend Energon - Superlink Cybertron - Galaxy Force but the 3rd series, Cybertron, was originally a self-contained series, the American version edits the dialogue to make it appear as a sequel to Armada and Energon. Also, the character Override, who is female in the US version, is male in the Japanese. In other words in Japan the first 2 are in the same continuity and the 3rd is a another reboot.

Q: Transformer Uk = 4.5% What does it mean?: Transformer short-circuit impedance, that is, his own impedance. The impedance is large, the transformer needs to resist the short circuit current multiplier is small, relatively speaking, anti-short circuit capability, but the transformer's external characteristics (volt-ampere characteristics) soft (with the transformer output current increases, the output voltage - transformer Voltage drop is very powerful). On the contrary, short-circuit impedance is small, the transformer needs to resist the short-circuit current multiplier, requiring a strong anti-short circuit transformer capacity. Of course, the external characteristics of the transformer better. Another short-circuit impedance will also affect the transformer manufacturing costs. He is not the bigger the better, nor the smaller the better. To be considered, so there are strict rules in the national standard.

Q: I live at an apartment complex and I was just returning from work when the entire complex went completely dark. All 12 buildings went offline at the same time, along with the outside lights and the covered parking lights. Since each building has its own transformer, shouldn't they be independent of the others? Why did all 12 buildings and the outside lighting go out together? Are they all on one line or something?: Failure of feeding line from the station. The transformers are independent.
