Model designation

Performance characteristics
1.A multilayer cylinder structure is used for all high voltage windings in order to improve the voltage impulse distribution of windings.
2.For the capacity range of low voltage windings is from 30kVA to 2000kVA,the cylinder type or spiral structure is used to ensure the high mechanical strength,ampere lure distribution,and excellent short-circuits proof performance.
3.The securing structure is set in the transformer body,which is used for ensuring that no displacement will occur during the transportation;meanwhile,the turnbuckles are mounted in fasteners,which is for assuring that fasteners will not be loose during the long term operation.
4.Corrugated tanks are used in transformer for replacing the conservator.The tank enclosure and rim are completety sealed by welding or bolting up,which prolongs the service life of transformer oil.
5.The transformer surface are painted with primer and finish coats after derusting,and phosphorizing;which can meet the special operation requirements in metallurgic and petrochemical industries,as well as,in moist and dirty places.
6.The press relief valves,signal thermometers,and gas relays are equipped in the oil tank of hermetically sealed transformer in order to the standard requirements for safe operation.The transformers are attractive and competitive due to the compact shape,excellent design,and maintenance-free.

Q:old transformers cartoons.what did you think of them?
I loved the original Transformers' cartoon. Optimus Prime was the ultimate good guy and Megatron the paramount bad guy. No matter the odds the Autobots never gave up. Some of the coolest characters were Autobots and Decepticons. The Dinobots were just freaking cool and I always like Soundwave. The only reason the movies even had a chance of success was that they brought back the original voice of Optimus Prime. Optimus dying was a shock to be sure, but they still did a good job without him for awhile. I have happily introduced my son and daughter to the original series and they both liked it more than the new movies. It is okay you don't like the original cartoons. They aren't everyone's cup of tea.
Q:What do I need to consider or what formula I can use to calculate Z (Impedance) in a Transformer?
It's pretty difficult to calculate the impedances (there's more than one) entirely from the transformer's design data. It's easier and more usual to decide on an equivalent circuit (there are plenty available depending on how well you want to model the transformer) and then to determine the parameters by a mix of calculation and measurement. A pretty basic equivalent circuit which refers all impedances to the primary side, has the primary terminals connected first by Xm and Rc in parallel (the magnetising reactance and core loss resistance) and then by a third parallel branch containg a series connection of leakage reactance Xl, winding resistance Rw and an ideal transformer of turns ratio Np/Ns. Xm is best obtained from an open circuit test but could be calculated as the inductance of the primary winding. For the latter you'd need to know core dimensions, number of winding turns and the magnetising characteristic of the core iron. If you have conductor sizes and conductivities you can calculate the winding resistance Rw, referring the secondary part to the primary by multiplying it by (Np/Ns)². You can deduce Rc from the losses measured on open circuit at nominal voltage and Rw from dc resistance measurements on the windings. If you know the specific hysteresis and eddy current losses of the core material, you can also have a good stab at calculating Rc. The leakage reactance is quite difficult to calculate from first principles - even designers usually resort to some empirical factors. Basically it's determined from the short circiut test which is at nominal secondary current. The ratio of primary volts to secondary surrent (referred of course) on secondary short circuit will get you close to Xl - you can adjust for Rw which can be determined from the losses on short circuit (core losses are absent here!) or by the two methods indicated above. It's normally Xl that's referred to as the transformer reactance and together with Rc and Rw, the impedance.
Q:doesn't the working of a transformer violate the ohm's law ?
Transformers don't need electricity to run!
Q:What is Transformer: UNiverse?
Transformers universe is a hasbro line Its not a company
Q:Transformers Animated Series?
It comes on after Ben 10 AF so i desperate to computer screen Transformers lively sequence, just to furnish it a attempt, and the 1st factor I had a concern grow to be with the animation It grow to be all uneven, and it did not look that great i'm not into the paintings form the two, and the villians are poor!! i would be trustworthy and say the teach seems low-budget, and wasn't theory out nicely I recommend, you have this impressive Transformers action picture, and you will possibly anticipate the lively sequence may well be great impressive (rather with all of the money they have) yet no, it purely sucks. it would be cancelled, heavily. it quite is purely horribly lively, and poorly made.
Q:Ipad 2 or asus eepad transformer what should i get?
Q:380V transformer always burn, how is it going
And voltage has nothing to do with a few seconds to install very hot, the secondary side must have a short circuit fault!
Q:1000KVA transformer no-load loss is how much?
I am in the "China Electromechanical Product Catalog" found a data, 10KV, S9-1000KVA no-load loss is 1.7KW, so the annual loss of power: 1.7 * 8760 = 14892KWH (degrees).
Q:Transformers Fall of Cybertron or Borderlands 2?
i love transformers also, i have borderlands one and the first transformers, get border lands because it is harder to beat and you can make as many charecters as you want and it has a longer story, youll get more for qwhat you pay for if you buy borderlands 2
Q:How come Transformers has made more money than Star Trek, Wolverine, Terminator, etc movies that have been mad?
the guys go crazy for megan fox.
