- 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.
- Because the voltage induced in the secondary winding depends on the *rate of change* of current in the primary winding: E M * di/dt. induced voltage mutual inductance * rate of change of current in other winding.
- Q:I just saw the movie and it has left me with a thirst for more on the story of transformersbut where can I turnComics, animated series?Thanks
- Transformers replaced right into a sketch coach an prolonged time in the past, and if the robots converted into something different than mechanical it might take out the feel. it could be like making Spider-guy into Cockaroach- guy. a million. If i replaced right into a Transformer, i might prefer to be a lip stick in basic terms for comedy, lol. 2. No it does no longer be handy, through fact each physique on the planet could be lifeless the 2d this occurs. 3. Gundam might win, through fact nicely, the destruction Gundams reason interior the anime is a few distance greater desirable than the wear and tear in Transformers a million/2. and that i think of that photograph is misguided, for Optimus best to punch Gundam, this is backwards. perfect solutions pelase ^__^ My arms injury from typing this xD
- Q:What are the technical parameters of the transformer?
- C, rated current (A): transformer in the rated capacity, allowing long-term through the current. D, no load loss (kW): when the rated frequency of the rated voltage applied to the end of a winding, the other winding open when the active power. And the core silicon steel sheet performance and manufacturing process, and the applied voltage. E, no-load current (%): When the transformer in the rated voltage under the secondary side of the load, the current through a winding, generally expressed as a percentage of the rated current. F, load loss (kW): the transformer secondary winding short circuit, in a winding rated tap position into the rated current, then the power consumption of the transformer. G, the impedance voltage (%): the secondary winding of the transformer short circuit, in a winding slowly increase the voltage, when the secondary winding short-circuit current equal to the rated value, then the voltage applied once the general. As a percentage. H, the number of phases and frequency: three-phase beginning to S said, single-phase start with D said. China's national standard frequency f is 50Hz. Foreign countries have 60Hz (such as the United States).
- Q:I have 13 lights with 12 volts 35 Watts on each light for each tree, the outlet is 120 volts current now. Should I buy 300Watt or 600Watt low volts transformer to supply all lights? Need your advise!
- The minimum transformer you need, with 80 percent safety factor, and internal inefficiency, is 500 W, so get the larger one.
- Q:i have been looking at transformers and i wanted to know a few things. will they do dc current? do they just add x amount of volts or do they multiply by x or just change to x? also there is a sort of container that goes around them is that carbon???? it goes all the way around and then through
- the average transformer you see on a power line, is takin a higher voltage and is distrubing down to what your house can handle which is usually 200amps. A transformer is nothing more than copper coils wrapped around carbon metal. And on the side of the transformer there is a voltage input and output tag. Transformer are huge and small. I work with them everyday.
- Q:I took apart a wall transformer before and soldered a single AA battery to the outputs and touched the what was before inputs and it gave me a shock. This is because it stepped up the power to something like 113v. Could I instead of a AA battery use 110 from the wall. Would it do the same thing. Or would it just overheat the transformer. And what would the amps be. I’m trying to make like a 20amp welder for just screwing around with.
- A standard transformer can step up the volts, sure. It's the basic isea behind things like a Tesla coil. It can also kill you. It's the volts that jolts, but its the mills (milli amps) that kills. A battery can't provide enough oomph to kill you. A 110v wall connection will do it without breaking a sweat. The small transformer might fizzle, buit that will be small comfort to those who find your corpse.
- Q:Usually the life of the transformer is called 20 years, is there any GB requirements? If there is a specific in that standard inside. Thank you for your thanks
- I can only give you in the transformer industry, we all agree that the argument: 1, before the transformer, the oil inside the transformer and air direct contact. As the transformer in the thermal expansion and contraction, the oil up and down fluctuations, we called the transformer in the breath, an increase of oil and air contact opportunities. The moisture enters the inside of the transformer. So that insulation is reduced. Under normal operation and maintenance, the transformer is guaranteed to have a life span of 20 years. 2, the current transformer, to take a fully sealed structure, oil pillow with sealed pocket, so that the transformer oil is not in direct contact with the air. Under normal operation and maintenance, the transformer life is 30 years
- 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:10 (6) What is the meaning of 10 and 6 in the KV transformer?
- One, 10 (6) KV transformer in the actual use of mostly oil-immersed transformers. It is also a distribution transformer, one of the important equipment in the industrial and mining enterprises and civil construction power supply and distribution system, it will 10 (6) kV or 35kV network voltage to the user to use the 230 / 400V bus voltage. 2, 10 (6) KV transformer 10 and 6 refers to the transformer primary side (input) voltage level is 10kV or 6kV. That is what we usually call the voltage of the high voltage line. It is mainly to 10 (6) kV network voltage down to the user to use the 230 / 400V bus voltage, which is commonly used in our 220 volts and 380 volts AC.
- Q:Here we go I have 4 transformers (230V to 12V) and 4 radio receivers. I have one transformer connected to one receiver. Similarly all transformers are connected in the same way. Now, I used a connection box (normal heavy duty ones bought at hardware shop-i think its made of some kinda fibre) to house 2 transformers and 2 receivers. This scenario is happening in my roof. I went to open one of the box the other and the transformer was hot. It wasn't hot to the point of not being able to hold it. But hot enough for me to hold it for for a while before letting go. So the basics here is that one transformer is only powering one receiver which is OK for the load. But I am a bit worried as to whether this can start a fire in the roof. Any advice please? Can this scenario lead to a fire? (Even though there is no overloading)
- Not knowing the rating of the transformer and the actual load on them, all I can do is give you generic answers: a) Transformers have a rating which is the continuous amount of load it can carry without overheating. b) Typically, a transformer can handle momentary loads at 125% of rating - but that is neither a good idea nor always accurate. And momentary means just that - a motor starting, for instance. With that in mind, if a transformer gets warm to the touch, it is probably working within its range. If it is hot to the touch, it is being overloaded. The generic rule-of-thumb is that if you can touch the transformer indefinitely, it is OK. If you have to remove your finger/hand in less than 3 seconds, you are far into the danger zone. If you have to let go after any period at all, you are in the danger zone. Check the rating of the transformer and the actual load of the receivers. Now, when transformers fail, they typically do so in a fairly spectacular manner. The coils get very hot, the insulation (varnish in most cases) fails, and they begin to short inside - getting hotter as they do so until they eventually either blow a fuse, open, or melt down. It is the last that absolutely *can* start a fire. But before that happens, they often toast whatever is connected to them as well.
