Q:How to open a transformer?
Transformers are not usually made to be opened. There is usually no point. There is nothing inside but tightly packed bundles of copper wire coated with something. They are repairable easily in a shop that knows about the design of that particular transformer. They know how to open them, but there is usually no way for a user do it. Mayan
Q:G1 Transformers Series?
Even though the original Transformers series is brilliant in it's animation, voice acting, and overall robot-lazer battle-isciousness; it most definitely is not worth that much money. Even if the special features are epic. However, many websites have links to the episodes online, so you can watch the OG Transformers over the inter-tron. Or the gumple-tron, which is an entirely unexplored medium of wireless communication yet unknown to humans.
Q:Is there a fourth Transformers?
There MAY be a script in the works. I'm just guessing.
Q:Transformers and frequency question?
Your answer is correct. The frequency has no effect on the turns ratio. The frequency does effect the required primary inductance, however. More turns with 50Hz, about 20% more for same magnetizing current as with 60Hz. I am assuming your generator can change frequency.
Q:twilight vs transformers?
i like them both even though i like twilight. I still like to watch transformers. I like them both.
Q:Transformer copper row selection
Answer: no love language, all the text is boring.
Q:Transformer parameter interpretation
I, temperature rise and cooling: transformer winding or the upper oil temperature and the temperature difference between the ambient temperature of the transformer, known as the winding or the upper oil temperature rise. Oil-immersed transformer winding temperature rise limit of 65K, oil surface temperature rise 55K. There are a variety of cooling methods: oil from the cold, forced air-cooled, water-cooled, tube, chip and so on. J, Insulation level: Insulation class standard. Insulation level of the method for the following example: high voltage rated voltage of 35kV level, low voltage rated voltage of 10kV level transformer insulation level expressed as LI200AC85 / LI75AC35, which LI200 said the transformer high voltage lightning impulse withstand voltage of 200kV, power frequency withstand voltage For the 85kV, low voltage lightning impulse withstand voltage of 75kV, power frequency withstand voltage of 35kV. Oaks High Technology Co., Ltd. The current oil-immersed transformer product insulation level LI75AC35, said the transformer high voltage lightning impulse withstand voltage of 75kV, power frequency Withstand voltage of 35kV, because the low pressure is 400V, can not be considered. K, the connection group label: According to the transformer one. Secondary winding phase relationship, the transformer winding connected into a variety of different combinations, known as the winding group. In order to distinguish between different groups, often using the clock representation, that is, the high voltage side of the voltage phase of the clock as a long needle, fixed on 12, low voltage side of the phase voltage as the clock short needle, (A) is a (triangular) joint, and the secondary winding is a (star) junction with a center point, and the group number is (11).
Q:ok, i have a transformer and i need to know how high boost the electrical output.?
cule is totally wrong. Transformers only work with AC, not DC But even with AC, transformers do not boost power, they only boost voltage, with a lower current. Use more batteries, such as several 9 volt batteries
Q:Installing a 70-volt speaker transformer?
Briefly, the reason for the multiple wires is so that a given transformer provides the option to select any of a variety of output watts, depending on its application. In other words, instead of a system installer having 1/2W transformers for classrooms, 1/16W transformers for tiny study rooms, and 2W transformers for hallway speakers, they use mostly ONE type of transformer for the majority of the installation, and select appropriate “tap” settings for each speaker's application. These selection possibilities may or may not be marked on the transformer, however! I used to use transformers that had center-tapped dual primaries that could be connected either in various series or parallel combinations, providing a whole range of wattage possibilities. This was done by looking at the spec. sheet and using any of 8 or so different wattage hook-ups by interconnecting the appropriately colored wires. Not all were used, depending on the desired wattage. There were NO markings on the transformer itself, other than the part number! I don't know your situation (or your transformer), but in general: The 70-volt line output covers the distance to the transformer-plus-speaker location, the transformer wire taps are selected for the desired output wattage to the selected speaker, and the sum of all the speaker wattages must be less than that of the amplifier rating. However, knowing the matching transformer's capability and wattage selection scheme is a key element. With luck, the secondary is marked for the speaker impedance (“common”, 4-ohm, 8-ohm, etc.) and the primary is marked for wattage (“common”, 1/4W, 1/2W, 1W, 2W, 5W, etc.). With that type of transformer, the amplifier might connect between C and 5W, and the speaker between C and 8 for example but as I said, that's if you're lucky!
Q:single phase transformer?
you may get the comparable voltage out of one output as in case you had related all 3. the different 2 might have decrease voltages for the period of them. case in point, say the transformer replace into regularly a 240 to 480 3-section delta. in case you have been to place 240 for the period of legs A and B, you may get 480 for the period of A and B of the output. i've got self assurance the B/C and C/A outputs might have 240 each and each, because of the fact the unconnected C section might seem as a midsection-faucet to the A and B legs
