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:I just saw the movie and im still trying to take in all that just happened. It was pretty awesome, and for me being a transformers fan since i was little (im 17) i got really connected to the characters. other viewers just familiar with the movie might not feel the same way. like when ironhide was killed, i was like hellll no wtf just happened. i was so mad. And when sam killed my all time favorite character starscream. I was so upset that he died that way. Just curious of your thoughts on the movie and if you think there will be a 4th. (i think so but not for maybe 4 or 5 years). Even though they killed off starscream,ironhide, megatron, etc. They can always come back as galvatron and all that, plus theres still unicron thoughts?: Michael Bay already said he wasn't going to make a 4th one (I think) Anyway, I was definitely pissed when Ironhide died. I've been writing fanfiction on Fanfiction for years, and you get connected so easily with the characters, and right now, Transformers is my main thing to write about. I thought the movie was awesome. Truly epic. It was so sad when Wheeljack (Known as Que in the movie) died. He was so innocent. Just your typical engineer/scientist who was doing his job and how he died was really heart wrenching. I did cry when Ironhide died. Like I said, you get so connected to the characters when you spend years writing about them. I hope Bay changes his mind and makes more Transformers movies. I'd definitely watch them!

Q:!!! I took a cardboard cylinder from a used firework, dug out all the crap, wrapped 160 turns of tinned copper wire on the outside tight and evenly so it is a beautiful solenoid, held it in place with 2 rubber bands. That was the secondary. Then I wrapped an insulated steel wire around a screwdriver shaft 10 times, stretched it out a little inserted a chopstick into this primary and inserted the chopstick into the firework. I then held it all in place with tissue paper and tape and wired the primary up to a pulsed DC circuit which was made of 3.0 volts wired to a steel file which I rubbed the electrode across. The secondary was wired to a current detector but I got no signal! Why is there zero inductance in my transformer and why is there no current at all? It can't even light up a small lightbulb!!: I think your current detector was not good enough. Was it a bulb? It wouldn't supply enough current for one. I'd suggest you need a more sensitive indicator. What you should see is about 48V. AC on the secondary, plus some more due to the inductance of the primary. Your electrode you rub on the file must be very small, such as the end of a wire, to give an interruption. You could probably get an indication on a digital multimeter on an AC range. Just don't expect it to be an accurate reading. If you're game, you could hold one end of your secondary in your fingers, and touch the other end to your tongue, then do the file thing. But you might only want to try once! I often use my tongue for low voltage indications. But 48V. would be a bit much for me. Ouch!

Q:I would like to input DC9V voltage into 12V, 15V multi-channel, how to do the details of the master: DC-DC converter can be used, its working principle is: the input DC voltage through the oscillator into high-frequency AC, and then by the high-frequency transformer boost, and then rectification to get the required DC voltage.

Q:does anyone know what the songs are in transformers???????: Linkin Park - What I've done

Q:A transformer is a two coil component that uses electromagnetic induction to pass an AC signal from its input to its output.?How and why are transformers used on electric wires? What would be their purpose??Why do we hear that these transformers break at times?: 1. Transformers are used to step up (or step down) AC voltage/current. Further, they can provide electrical isolation from two circuits (There is no physical connection between the two sides of a transformer). 2. Transformers can break for a lot of reasons, i.e. excessive heat, too large of a load, environmental breakdown, faulty manufacturing, etc

Q:800KVA transformer itself is the loss of how much?: S9 type oil change 800kVA Calculation results: no-load loss 1400 watts load load loss of 7500 watts. Calculation formula of transformer loss (1) active loss: ΔP = P0 + KTβ2PK ------- (1) (2) Reactive power loss: ΔQ = Q0 + KTβ2QK ------- (2) (3) Integrated power loss: ΔPZ = ΔP + KQΔQ ---- (3) Q0 ≈ I0% SN, QK ≈UK% SN Where: Q0 - no load reactive power loss (kvar) P0 - No load loss (kW) PK - rated load loss (kW) SN - transformer rated capacity (kVA) I0% - transformer no-load current percentage. UK% - short circuit voltage percentage Β - average load factor KT - load fluctuation loss coefficient QK - rated load leakage power (kvar) KQ - Reactive power equivalent (kW / kvar) Selection of the parameters of the above formula: (1) take KT = 1.05; (2) The reactive power equivalent KQ = 0.1kW / kvar when the 6kV ~ 10kV step-down transformer of the urban power grid and industrial enterprise power grid adopts the minimum load, (3) the average load factor of the transformer, for agricultural transformer desirable β = 20%; for industrial enterprises, the implementation of three shifts, desirable β = 75%; (4) transformer operating hours T = 8760h, the maximum load loss hours: t = 5500h. (5) transformer no-load loss P0, rated load loss PK, I0%, UK%, see the transformer signs shown.

Q:I fried a transformer in my lathe. I went to the electrical supply near my house and the got me a new transformer and said it will work. The old transformer is 3 times bigger. they are both 100VA. the voltage on the original is 230v in and 100v out. It powers the on/off switches for the forward/ reverse micro switches. from the micro switch it powers the magnetic puill in for the contactors. The contactor say 100V.will using a 110v transformer cause and problems or issues?Should I return the one I purchased and order a 100V ?I have work piled up and waiting and really need this lathe operational ASAP.Thank You in advance for any information.Earle: No, contactors and other electromechanical switches should be rated for at least twice the supply voltage, because of inductive voltage spikes during circuit opening.
